Error p0730 mazda

error p0730 mazda

Seems that the gear not shifting up gets locked. Scanner couldn't diagnose when model is entered but the equivalent Mazda throws the codes P and P . Took it to a mechanic, the car computer showed a gear ratio error (I dont know for sure, but I think it was - P Incorrect Gear Ratio). Error Code P means the automatic transmission is experiencing a problem, which is usually caused by dirty transmission fluid or problems.

What Transmission Do I Have?

What Does P Mean?

“Transmission Control System Malfunction” is the definition of OBD-II Trouble Code P

By automatically selecting different “speeds” or gear ratios to deliver power to the wheels, an automatic transmission’s goal is to match the optimal torque and power characteristics of the engine to the desired speed and rate of acceleration of the driver.

When the TCM (or transmission control module) sees an RPM difference (rotational speed) between the transmission output RPM sensor and input RPM sensor that is greater than a certain value, the P code is triggered. This can happen while shifting between gears or when driving at a steady speed in a particular gear.

Symptoms of P

  • Illumination of the Check Engine light
  • Fuel economy decreases
  • Shifting of the vehicle is delayed or goes into wrong gear
  • Transmission slipping
  • There may be misfire-like symptoms, dying when coming to a stop after freeway driving, or other performance issues in some cases
  • The driver may not notice any adverse conditions in some cases

Common Causes of P

  • Faulty torque converter clutch
  • Faulty shift solenoids
  • Blockage on the inside of the transmission main control
  • Internal mechanical failure of the transmission
  • Blockage in fluid lines
  • Clogged fluid filter or worn pump
  • Dirty or low transmission fluid

How to Diagnose the P Code?

The level of fluid in the transmission should be noted and checked for quality before doing any other diagnostic tests. You should replace any dirty or old fluid.

In the hands of a qualified mechanic, an OBD-II scanner diagnoses the P code. With this, they can view any needed info from the engine in real-time. The technician will take the vehicle for a test drive after clearing the code.

The code is due to an actual condition within the transmission if it comes back again. To determine if the engine stall speed fits factory specifications, the mechanic might perform a torque converter stall speed test.

Common Mistakes When Diagnosing

Common misdiagnoses include an internal transmission problem and engine misfire. The symptoms you are experiencing may simply be due to dirty or low transmission fluid. The transmission problems that are causing the trouble code may be resolved by simply replacing or topping off the fluid.

What Transmission Do I Have?

What Repairs Will Fix the P Code?

  • Wires connecting sensors to the transmission control module and other electrical connections should be inspected.
  • Any damaged or corroded wires in and near the transmission control module should be repaired or replaced.
  • Parts in the transmission might need to be repaired or replaced if the transmission wiring and fluid are all in working condition.
  • The transmission must be removed if there is a problem with the torque converter, shift solenoids, or pump.
  • To be sure that it operates without the P code or any other trouble codes, the transmission should be reinstalled and inspected once the needed repairs are completed and before testing.

P code definition

The P code identifies a problem within an automatic transmission. The P code is often associated with the P, P, P, P, P, P, and P trouble codes.

What the P code means

P is the OBD-II generic code for an incorrect gear ratio detected in an automatic transmission. The ratio of a combination of engine speed and throttle position and the speed of the transmission is used to determine what gear the transmission will use when driving. If there is a problem with any gear within the transmission, then the P code will appear once this ratio is calculated from the sensor data in the transmission.

What causes the P code?

The incorrect gear ratio code may have several causes:

  • Bad or dirty fluid in the transmission
  • Low fluid in the transmission
  • Broken mechanical components within transmission
  • Internal blockage in fluid lines
  • Bad transmission control module
  • Problem with the torque converter clutch
  • Problem with the shift solenoids

What are the symptoms of the P code?

Eventually, the P code will cause the Check Engine Light to illuminate on the dashboard. Along with this indicator, there may also be slipping within the transmission and poor overall transmission performance. The transmission may stay in a low gear for too long, or stay in a high gear until the engine stalls. Fuel economy may worsen as well.

How does a mechanic diagnose the P code?

Prior to further diagnostic tests, the fluid in the transmission should be checked for quality, and the level of fluid should be noted. Old or dirty fluid should be replaced.

The P code is diagnosed with an OBD-II scanner in the hands of a qualified technician. This will provide them with the necessary information from the engine that they can view in real-time. The code will be cleared and the mechanic will take the car for a test drive. If the code comes back, then the code was caused by an actual problem in the transmission.

Depending on the severity of the issue, the technician may perform a torque converter stall speed test to determine if the engine stall speed is within factory specifications. The engine speed must match the readings from the transmission sensor.

Common mistakes when diagnosing the P code

The biggest problem that pops up when diagnosing the P trouble code is that the symptoms may all be stemming from low or dirty transmission fluid. Topping off or replacing this fluid may solve all of the issues in the transmission triggering the trouble code.

How serious is the P code?

The severity of P code depends mostly on the application. In some cases, minor issues can trigger the code, due to the fact that any abnormality in the transmission speed will trigger it in any gear. It could also be triggered when there is a major problem with the transmission, rendering it unable to change gear, though it would likely be accompanied by other, more specific trouble codes.

When the P code appears it is best to have it diagnose by a qualified technician. In many cases, the problem goes away as soon as the code is reset once, especially in cases where the Check Engine light appeared immediately upon startup.

What repairs can fix the P code?

The most common repairs to address the P code are as follows:

  • Inspect electrical connections and wires connecting sensors to the transmission control module.
  • Repair or replace any corroded or damaged wires in and around the transmission control module.
  • If the transmission fluid and wiring is all in working condition, then components in the transmission itself may need to be repaired or replaced.
  • If there is a problem with the pump, shift solenoids, or torque converter, then the transmission will have to be removed for the repairs to take place.
  • Once the necessary repairs are made, the transmission must be replaced and inspected before being tested to ensure that it works without any trouble codes, including the P code.

If the Check Engine Light comes on because of the P trouble code right when the vehicle starts, then it can probably be fixed by simply resetting the code. Small problems with the wiring, common in aging vehicles, can easily trigger certain trouble codes without the presence of a serious problem. When the P code appears, it often does so alongside several other error codes.

p help tranny issue HELP!!!

hi i have a mazda protege which says incorrect gear ratio p help please!!! it starting giving me this code suddenly no warning signs etc the gears were not slipping or anything just one night while i was driving i felt the tranny downshift and upshift abnormally it was like the car was confused as to which gear to select!!
things i tried so far: flush out old tranny fluid was using redline d4, fluid was nasty btw. changed the filter under the valve body and put in fresh redline d4 around 3 and a half quarts anyways can anyone assist me with this problem thanks

update!!


Ok i checked the resistance between the terminals of the turbine input speedsensor got and according to the manual it should be between and ohms anyways what else can i try? or i tried it when the sensor was cold and outside the tranny btw.

changed the turbine speed sensor with a used still no good a I got a mech/tranny guy to drive it today he said it feels like one of the shift soleniods is gone but when im checking with my multimeter for resistance it seems ok can that really be a problem??


ok took out all the soleniods test them for resistance and current tested ok one note though soleniods d and e dosent click like the rest of the soleniods there shaped differently mabe they just work another way can anyone shed light on this?? becuz the manual said that all the soleniods sopposed to click when a 12v is applied to them thanks!!

The P error code sounds like &#;incorrect gear ratio&#;. Often, in programs working with an OBD-2 scanner, the name may have the English spelling &#;Incorrect Gear Ratio&#;.

Datasheet and explanation of the P code

This Diagnostic Trouble Code (DTC) is a generic transmission code. The P code is considered a generic code as it applies to all makes and models of vehicles. Although the specific repair steps may differ slightly depending on the model.

This code can appear on vehicles with an automatic transmission. When there is a problem with shifting or engaging any gear. The error code is generic and does not specifically indicate any gear ratio failure. The computer controlled automatic transmission uses multiple gear ratios. For increasing vehicle speed while maximizing engine power output.

Newer vehicles can have more than four gear ratios to improve fuel economy. The computer determines when to shift up or down, depending on the throttle position and vehicle speed.

The engine control module (ECM), powertrain control module (PCM), or (TCM) use input from various sensors. To check the correct operation of the transmission and its components. Engine speed is often calculated from a transmission speed sensor to determine gear ratio and torque converter slip.

If the calculation does not match the desired value, P OBD2 DTC sets and the check engine light comes on. Incorrect ratio codes usually require a mechanical as well as a diagnostic check with a scanner.

Malfunction symptoms

The main driver symptom of a P code is a MIL (Malfunction Indicator Light) illuminated. It is also called Check engine or simply &#;check is on&#;.

They can also manifest as:

  1. The control lamp &#;Check engine&#; in the control panel will come on (the code will be written in the ECM memory as a malfunction).
  2. Delay in shifting or not shifting to any gear.
  3. Automatic transmission slipping.
  4. Increased fuel consumption.
  5. Sometimes, drivers may not notice any signs of this error.

Reasons for the error

The P code could mean one or more of the following problems have occurred:

  • Low or dirty ATF.
  • Blockage of transmission fluid passages.
  • Mechanical failure of the box.
  • Locking inside the main transmission regulator.
  • Defective gear shift solenoid.
  • Damaged or defective PCM.

How to Repair or Reset DTC P

Some suggested steps to troubleshoot and fix the P code:

  1. Any damaged circuits and connectors in the system should be checked, repaired, or replaced.
  2. Any damaged or defective components inside the transmission should be replaced.
  3. Check and, if necessary, replace the defective PCM.
  4. If the problem is a low level or contaminated ATF, the fluid must be topped up or replaced.

You should also pay attention to other error codes. Which could appear along with the P code. They can help determine which parts need repair or replacement.

Diagnostics and problem solving

Be sure to check the ATF level and condition before proceeding with troubleshooting P Wrong fluid level or dirty fluid can cause shifting problems. Affecting the operation of multiple broadcasts.

Transmission clutches are usually controlled by a solenoid or fluid pressure. If there is an electrical problem with the shift solenoid. Then a code related to this malfunction should be displayed. Correct the electrical problem before proceeding.

Clogged passages interfere with the circulation of fluid inside the transmission, which can also cause the P code. If there are multiple gear ratio error codes, but the transmission is working properly. There may be a mechanical problem with the torque converter, main transmission control, or pressure problems.

It may be necessary to use a diagnostic scanner to determine which gear is being controlled by the transmission. And determine if the engine speed matches the calculated output speed from the transmission sensor.

Troubleshooting these types of faults often requires knowledge of transmission and overhaul. Check the factory service manual for specific diagnostic procedures on the vehicle.

On what cars does this problem occur more often?

The problem with the P code can occur on different cars, but there are always statistics on which brands this error is more common. Here is a list of some of them:

  • Acura (Acura MDX, TL)
  • Audi (Audi a4, Audi a6, Audi a8)
  • BMW (BMW E39)
  • Chery (Chery Tiggo)
  • Chevrolet (Chevrolet Malibu)
  • Chrysler (Chrysler )
  • Citroen (Citroen C4)
  • Dodge (Dodge Intrepid, Caliber, Charger)
  • Ford
  • Honda (Honda Accord, SRV, Civic)
  • Jeep (Jeep Compass)
  • Land Rover (Land Rover Range Rover)
  • Mazda (Mazda Demio, Capella, Premasi, Family)
  • Mercedes (Mercedes ml, ml, SLK, w, w, w)
  • Mitsubishi (Mitsubishi Outlander)
  • Opel (Opel Astra, Vectra, Corsa, Omega)
  • Peugeot (Peugeot )
  • Suzuki
  • Volkswagen (Volkswagen Passat)

Other errors can sometimes be found with DTC P The most common are the following: P, P, P, P, P, P, P, P, P, P, P, P, P, P, P, P, P, U, U

Mazda gear ratio problem

DefaultMazda gear ratio problem

Hi,

I have a Automatic Mazda Lantis and yesterday I have experienced a Gear problem. when hitting the gas, and the engine had gone to about ~4k RPM, the "hold" light came on, and the car shift into a limp mode, I believe it only uses the 2nd and 3rd gears.

I tried reseting the computer, It worked fine for meters, then I hit the hold button - still everything was ok, push the gas a bit more to a higher RPM, and it happened again, the hold light came on and back on limp mode.

Took it to a mechanic, the car computer showed a gear ratio error (I dont know for sure, but I think it was - P Incorrect Gear Ratio). the mechanic called another mechanic who's expertise is "Gear", and he sais we should try replacing the oil and all the fluids. if that doesn't work - it needs the replacement or rebuilding the whole gear system.

I would like to know, if there is a problem that wouldn't be solved by changing the fluids, couldn't be a simpler/cheaper solution???

 

P Engine Trouble Code

P Engine

When you check engine light came on code P the reason should be Engine Light ON (or Service Engine Soon Warning Light). However your vehicle's manufacturer may have a different definition for the P OBD-II Diagnostic Powertrain (P) Trouble Code. So you should chech it on our car models.

P if your catalytic convertor fails completely, you eventually won't be able to keep the car running its engine. Your gas mileage will also be not working properly, so you should try and fix it as soon as you can. Unfortunately, the average replacement cost is around $2, and you can't do it yourself unless you're an experienced mechanic service for your car.

P Code Meaning :

P
OBD-II Diagnostic Powertrain (P) Trouble Code For Engine

0
Intake Valve Control Solenoid Circuit Low

7
Throttle/Pedal Position Sensor/Switch A Circuit Intermittent

3
Cold Start Injector 1 Malfunction

0
Exhaust Gas Recirculation Sensor B Circuit High

The oxygen (02) sensors on your car measure the oxygen in the exhaust to determine how rich or lean the ratio of fuel and air are in the cylinders. Optimizing this mixture means better fuel economy and fewer exhaust emissions.

P OBD-II Diagnostic Powertrain (P) Trouble Code Description

P OBD-II Trouble Code This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by Transmission Control Module (TCM) as follows: P code. Throttle/Pedal Position Sensor/Switch A Circuit Intermittent and Cold Start Injector 1 Malfunction causes most of code P

Reason For P Code

The reason of P OBD-II Engine Trouble Code is Throttle/Pedal Position Sensor/Switch A Circuit Intermittent.

Your car parts or components should not be replaced with reference to only a P DTC. The vehicle service manual should be consulted for more information on possible causes of the error code, along with required testing.

How To Repair P Code

Before starting let's see P repairing process steps:

  • Qualified technicians will begin by using a scan tool to access P code stored in the ECU.
  • Technicians will note P code present and any freeze frame data associated with them.
  • After all, if you sure the engine trouble is finished, the code will be cleared.

When detecting a faulty oxygen sensor, your car will be working less efficiently, so it will periodically hold a defective idle, abnormal jerking at an accurate throttle, errors with hard starting, thus all of these symptoms will cause a high fuel consumption that induces you into detecting for an engine light to illuminate.

The computer installed in each fuel-injected vehicle has to be aware of two factors before it can solve the proper cold-start air/fuel compound: the engine coolant temperature and the exterior air temperature. Your symptoms are exactly the same to a faulty engine coolant temperature sensor (ECT). The computer is measuring an air/fuel compound that is excessively meager.

Sometimes P code comes with P code.

Diagnosis Of Engine Error OBD Code P

It's essential to diagnose this trouble code. Then are some way which a handyperson should follow for diagnosing the problem that started a P trouble code to be stored

The first step is introductory and is about reacquiring all the canons that have been set. For this, the individual scanner will have to be plugged into the individual harborage of your vehicle. Make sure you indurate frame the data. Any canons that were set previous to the P code will have to be sorted first, as they may have been the reason for the law to set in the first place. It's always good to rule that out.

The coming step is to run a introductory examination of all the electrical circuits, connectors, wiring etc for damages similar as becks, erosion, fraudulent legs etc. All of these will have to be repaired or replaced. After that's sorted, clear the canons and go on a test drive to see if it resets. In case it resets, you'll have to continue your opinion. Depending on your vehicle you may have a vacuum operated selector or a vacuum solenoid if it's electrically actuated. In the case of the former, a hand held vacuum pump will have to be used to sprers.eu purpose is to see if the internal stopcock is getting turned by the selector, motor or solenoid. In order to do this, a command can be transferred to the system with scanner or by driving the vehicle under the special conditions that will spark the system. While this is passing keep an eye on the checkup tool data for the result.

Error Code P Incorrect Gear Ratio

Error Code P is described as Incorrect Gear Ratio. This means the automatic transmission is experiencing a problem, which is usually caused by dirty transmission fluid or problems with shift solenoids.

This code is a generic trouble code, meaning it applies to all vehicles equipped with the OBD-II system, especially those vehicles made since up to present. Specifications on the definition, troubleshooting, and repairs of course, vary from one make and/or model to another.

Definition

Modern vehicles that come equipped with automatic transmission or tranaxles use a torque converter between the engine and transmission to improve the torque output of the engine and drive the rear wheels. The PCM (powertrain control module, also known as ECM or engine control module in other vehicle makes), controls automatic transmission by using multiple gear ratio and increase the vehicle speed to maximize the engine’s power output. Newer vehicle models are equipped with more than four gear ratios for fuel efficiency. The PCM decides when to shift up or down between gears, based on the vehicle speed vs. throttle position. It does so by using the input coming from various sensors to verify the correct operation of the transmission and all its components.

Thus, Error Code P happens in automatic transmission when there is a problem on the shifting or driving to any gear. As a generic trouble code, P also doesn’t pinpoint to any gear ratio failure.

Other related codes include:

Error codes P, P, P, P, P, P and P

If there are other transmission code problems, they should be fixed first before fixing the incorrect fear ratio code.

Common Symptoms

As with other error codes P triggers the Check Engine light. Common symptoms of this error code may include the following:

  • Delayed shifting or vehicle not shifting into the right gear
  • Slipping transmission
  • Decrease in fuel efficiency

Possible Causes

Error Code P can be caused by multiple factors, such as:

  • Insufficient or dirty transmission fluid
  • Clogged fluid filter or worn pump
  • Solenoid, torque converter clutch or internal blockage
  • Internal blockage in transmission main control
  • Mechanical failure inside transmission
  • Faulty shift wirings or solenoids
  • Faulty transmission control module
  • Defective torque converter clutch

How to Check

Before starting the diagnosis, mechanics would first check the transmission fluid’s level and quality. Old and dirty fluid must be replaced.

To diagnose this error code, technicians use their OBD-II scanner to view real-time information. To codes will then be cleared and the vehicle will be taken for a test drive. If the code comes back, then the problem is really caused by an actual failure in the transmission.

Depending on the severity of the problem, technicians may perform a torque converter stall speed test to determine whether the stall speed of the engine is within the factory specifications or not. The engine must be able to match the readings from the transmission sensor.

How to Fix

Depending on the result of the diagnosis, the repairs for this error code are as follows:

  • Check all electrical connections and wires that connects the sensors to the transmission control module
  • Repair or replace damaged or corroded wires in and around the transmission control module
  • If transmission fluid and wiring are both in good shape, transmission components must be checked for issues and repaired, or replaced if necessary
  • If there are problems with the shift solenoids, pump, or torque converter, the transmission must be removed for proper repairs of these components
  • After conducting the necessary repairs, the transmission must be replaced and checked before being tested to make sure everything works properly without the trouble codes, including P

Low or dirty transmission problem is probably the most common cause of this error code. Thus, by simply replacing the dirty fluid, the issue can be resolved.

The fact that any abnormality in the transmission speed will trigger problems to the gear, the severity of the problem can vary. In severe cases, the problem could trigger major transmission issue, rendering the vehicle unable to change gear. However, it could also be accompanied by other specific trouble codes.

Because of the complexity of the transmission problem, it is always best to have this code diagnosed and repaired by a qualified technician as soon as possible.

P Mazda Clef Diagnostic Trouble Code

P Mazda Clef code definition:
P is a kind of OBD-II Diagnostic P-Powertrain Diagnostic Trouble Code for Mazda Clef, error p0730 mazda.

P Mazda Clef is described as Oxygen Sensor Circuit No Activity Detected Bank 2 Sensor 1. This code appears when the Internal control module rom error p0605 (powertrain control module, also known as ECM or engine control module in other brands) remains at or close the set voltage point. So if the problem persists despite of your diagnosis, then you should never hesitate to take your vehicle to your error p0730 mazda or to a qualified mechanic.

Symptoms

Symptoms of a P Mazda Clef diagnostic error p0730 mazda code may include:
  • The light may stay on or light intermittently as the DPF regenerates. The engine will be sluggish on acceleration.
  • Faulty PCM
  • If the DPF is not cleared the ECU will revert to the "Limp Home Mode" until the situation is corrected
  • Diminished fuel efficiency
Place of P in engine

Possible Causes :

  • Faulty IMRC actuator/sensor
  • A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture.
  • An air leak forward of the DPF will change the sensor readings resulting in the code

Common Misdiagnoses

  1. TP Sensor Learn Not Complete Problem
  2. Low Coolant Circuit Problem
  3. Cruise Control System - Vehicle Accel Too High Problem
  4. TFP Valve Position Switch-Drive Without Drive Ratio Problem
  5. Problem

Repair Processes :

If the scan tool has that capability, and the scan tool can operate the IMRC valves, then the problem is either resolved and a simple code clearing is all that's left or a new PCM would be called for. If the engine displays a miss and there wasn't a code, determine which cylinder is misfiring. If the exhaust manifold is visible, spay or pour a small amount of water on each cylinder exhaust port. Water will evaporate immediately on good cylinders and slowly on the missing cylinder. If this can't be accomplished pull the plugs and check the condition. Find out what kind of system you have and verify that voltage to the fuel level sensor is present at the fuel pump wiring harness.

Process Tips

Diagnostic trouble code P Mazda Clef is not difficult to diagnose and repair. Thus, it always pays to have a qualified technician to look after your vehicle should this error code arise.

Diagnosing this code requires the engine to be in good running shape, without unmetered air entering the engine. If other codes that relates to misfiring condition, lean running or air entering the engine is present, then you must first fix those error codes before P Mazda Clef.

Fortunately, error p0730 mazda, P Mazda Clef is a fairly common OBD code, meaning that it applies to all makes and models of vehicles made after

error p0730 mazda Mazda OBD2 Code P Incorrect Gear Ratio

What Does P Code Mean?

OBD-II Code P is defined as a Transmission Control System Malfunction

The purpose of the automatic transmission is to match the engine's optimum power and torque characteristics to the driver's desired rate of acceleration and speed by auto-selecting different gear ratios or 'speeds' to power the wheels.

Code P means that the Powertrain Computer or PCM is seeing greater than a specified RPM difference between the rotational speed of the Input RPM Sensor and the Transmission Output RPM Sensor. This can occur during shifting or when driving at steady speeds in the same gear. It often implies that error p0730 mazda transmission is slipping.

P Symptoms

  • Check Engine Light will illuminate
  • Vehicle will not shift properly
  • Decrease in fuel economy
  • In unusual cases, there are no adverse conditions error p0730 mazda by the driver
  • In some cases, there may be performance problems, such as dying when coming to a stop after driving on the freeway and/or misfire-like symptoms

Common Problems That Trigger the P Code

  • Defective Shift Solenoids
  • Defective Engine Coolant Temperature Sensor
  • Defective Valve Body
  • Dirty transmission fluid that restricts the hydraulic passages

Common Misdiagnoses

  • Engine Misfire problem
  • Internal Transmission problem
  • Driveline problem

Polluting Gases Expelled

  • HCs (Hydrocarbons): Unburned droplets of raw fuel that smell, affect breathing, and contribute to smog
  • CO (Carbon Monoxide): Partially burned fuel that is an odorless and deadly poisonous gas
  • NOX (Oxides of Nitrogen): One of the two ingredients that, error p0730 mazda, when exposed to sunlight, cause smog

P Diagnostic Theory for Shops and Technicians

When diagnosing a P code, it is important to record the freeze frame information and then to duplicate the code setting conditions with error p0730 mazda test drive. Pay close attention to the engine load, throttle position, error p0730 mazda, RPM, and road speed and compare the Output RPM Speed Sensor signal to the Input RPM Speed Sensor signal, error p0730 mazda. If the input RPM signal varies a lot when your're traveling at a steady road speed and throttle error p0730 mazda, then you may have verified the P code setting condition.

I also like to drive the vehicle at a steady freeway speed, say 60 mph, so the transmission can shift into its highest gear. Then I watch the Input and Output RPM Speed Sensor signal. If there is more than a Bios error 501 difference at a steady speed and throttle position, I know the transmission is slipping and may need internal repairs.

Mazda gear ratio problem

DefaultMazda gear ratio problem

Hi,

I have a Automatic Mazda Lantis and yesterday I have experienced a Gear problem. when hitting the gas, and the engine had gone to about ~4k RPM, the "hold" light came on, and the car shift into a limp mode, I believe it only uses the 2nd and 3rd gears.

I tried reseting the computer, It worked fine for meters, then I hit the hold button - still everything was ok, push the gas a bit more to a higher RPM, and it happened again, the hold light came on and back on limp mode.

Took it to a mechanic, the warning mysql error computer showed a gear ratio error (I dont know for sure, error p0730 mazda, but I think it was - P Incorrect Gear Ratio). the mechanic called another mechanic who's expertise is "Gear", and he sais we should try replacing the oil and all the fluids. if that error p0730 mazda work - it needs the replacement or rebuilding the whole gear system.

I would like to know, if there is a problem that wouldn't be solved by changing the fluids, couldn't be a simpler/cheaper solution???

 

P code definition

The P code identifies a problem error p0730 mazda an automatic transmission. The P code is often associated with the P, P, P, P, P, P, and P trouble codes, error p0730 mazda.

What the P code means

P error p0730 mazda the OBD-II generic code for an incorrect gear ratio detected in an automatic transmission. The ratio of a combination of engine speed and throttle position and the speed 1075 mysql error the transmission is used to determine what gear the transmission will use when driving. If there is error p0730 mazda problem with any gear within the transmission, then the P code will appear once this ratio is calculated from the sensor data in the transmission.

What causes the P code?

The incorrect gear ratio code may have several causes:

  • Bad or dirty fluid in the transmission
  • Low fluid in the transmission
  • Broken mechanical components within transmission
  • Internal blockage in fluid lines
  • Bad transmission control module
  • Problem with the torque converter clutch
  • Problem with the shift solenoids

What are the symptoms of the P code?

Eventually, the P code will cause the Check Engine Light to illuminate on the dashboard. Along with this indicator, there may also be slipping within the transmission and poor overall transmission performance. The transmission may stay in a low gear for too long, or stay in a high gear until the engine stalls. Fuel economy may worsen as well.

How does a mechanic diagnose the P code?

Prior to further diagnostic tests, the fluid in the transmission should be checked for quality, and the level of fluid should be noted. Old or dirty fluid should be replaced.

The P code is diagnosed with an OBD-II scanner in the hands of a qualified technician. This will provide them with the necessary information from the engine that they can view in real-time. The code will be cleared and the mechanic will error p0730 mazda the car for a test drive. If the code comes back, then the code was caused by an actual problem in the transmission.

Depending on the severity of the issue, the technician may perform a torque converter stall speed test to determine if the engine stall speed is within factory specifications. The engine speed must match the readings from the transmission sensor.

Common mistakes when diagnosing the P code

The biggest problem that pops up when diagnosing the P trouble code is that the symptoms may all be stemming from low or dirty transmission fluid. Topping off or replacing this fluid may solve all of the issues in the transmission triggering the trouble code.

How serious is the P code?

The severity of P code depends mostly on the application. In some cases, minor issues can trigger the code, due to the fact that any abnormality in the transmission speed will trigger it in any gear. It could also be triggered when there iphone 4g error 14 a major problem with the transmission, rendering it unable to change gear, though it would likely be accompanied by other, more specific trouble codes.

When the P code appears it is best to have it diagnose by a qualified technician. In many cases, the problem goes away as soon as the code is reset once, especially in cases where the Check Engine light appeared immediately upon startup.

What repairs can fix the P code?

The error p0730 mazda common repairs to address the P code are as follows:

  • Inspect electrical connections and wires connecting sensors to the transmission control module.
  • Repair or replace any corroded or damaged wires in and around the transmission control module.
  • If the transmission fluid and wiring is all in working condition, then components in the transmission itself may need to be repaired or replaced.
  • If there is a problem with the pump, error p0730 mazda, shift solenoids, or torque converter, error p0730 mazda, then the transmission will have to be removed for the repairs to take place.
  • Once the necessary repairs are made, the transmission must be replaced and inspected before being tested to ensure that it works without any trouble codes, including the P code.

If the Check Engine Light comes on because of the P trouble code right when the vehicle starts, then it can probably be fixed by simply resetting the code. Small problems with the wiring, common in aging vehicles, can easily trigger certain trouble codes without the presence of a serious problem. When the P code appears, it often does so alongside several other error codes.
