<<See All OBD Codes

The trouble code P0A2F can be explicated as Drive Motor "A" Over Temperature. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model. The particular code which is triggered depends upon the specific fault which the PCM has detected. If there is some issue with the automobile’s Drive Motor "A" Over Temperature, then the P0A2F fault code would start flashing up.

Do you want to gain some more knowledge about the P0A2F trouble code? This code is a generic trouble code, meaning it applies to all vehicles equipped with the OBD-II system, especially those made from 1996 up to present. It’s also more common among Audi, Citroen, Chevrolet, Ford, Hyundai, Nissan, Peugeot, and Volkswagen vehicles. Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model, powertrain configuration type, to another.

What causes this problem with the Drive Motor "A" Over Temperature?

• An air leak further of the DPF may variate the sensor readings
• Faulty exhaust systems, cranny exhaust manifolds or quirky gaskets might give rise to air leaks.
• Fuel with a huge percentage of sulfur might jam the DPF fastly

1. Automatic Transmission Sensor - The P0A2F code can also arise due to some issues in Automatic Transmission Sensor. So, it is advised to replace them as soon as possible.
2. Engine Coolant Temperature Sensor - Do you remember when was the last time you got your car Engine Coolant Temperature Sensor checked up? A damaged Engine Coolant Temperature Sensor can cause a lot of issues like displaying P0A2F code.
3. Electronic Control Unit - Electronic Control Unit is an important car part which should never be neglected. May be there is some fault in it due to which P0A2F code may start flashing.
4. Powertrain Control Module - Is your Powertrain Control Module damaged or broken? Don’t worry as we have solutions for all your problems.
5. Engine Control Module - Defective car Engine Control Module can be a major reason why P0A2F code depicts. So, make sure to replace it online so that you don’t have to face any further issues.
6. Body Control Module Component - Everything is okay with the ECM and still OBD code P0A2F triggering? Then there must be some defects in Body Control Module Component. Replace them as soon as possible.
7. Auto Transmission Control Module - P0A2F code flashing? Get your Auto Transmission Control Module inspected from a mechanic.

It is vital to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P0A2F here:

Common Symptoms

• The light might stay ON or may light intermittently as the DPF revives. The engine will be stagnant on acceleration
• Malfunctioning PCM
• If there is no clearance of the DPF, then the electronic control unit will return to the "Limp Home Mode" until the situation is altered
• There might be a drop off in the fuel efficiency

The repairs which you will have to do to correct this fault code are simply straightforward; you can surely pinpoint the necessary repairs on the basis of your diagnosis. Have a look at some common fixes:

• It is essential to restore the quirky gasket
• Repair or replace the flawed electronic control unit
• Rehabilitate the faults in the engine control module
• Carefully adjust the defaults in the sensor
• Recondition the non-functioning exhaust system parts
• It is necessary to perform proper service of the unsound exhaust manifold

Here are some steps which you should follow in order to diagnose this fault code:

As an initial step the mechanic will carefully inspect the vehicle with the help of a scanner. After this, the technician will connect a scanner to the diagnostic code so that he can recover all the codes and freeze frame data. Note down this information as it can clearly help for further diagnosis. The mechanic will also inspect the shift solenoid to find if it is disconnected or if any other faults persist. After careful inspection, he will reset the code and test drive your vehicle to check for reappearance of the codes. He will know that an intermittent condition persists, if the code does not return instantly. But if the error code returns quickly, the vehicle is test driven, and then he has to inspect the transmission fluid. If any of the constituent is damaged, the mechanic will replace them quickly. Most often, whenever the mechanic carries out any repair work, he will reset the code and test drive your car, to check if the codes return immediately. This can preferably help the mechanic to know what caused this error code in the vehicle.

Common Mistakes When Diagnosing The P0A2F Code

• Problems related to the high voltage water pump
• High voltage coolant level might be less
• Failure in the inverter/converter assembly
