P0AF3 - OBD Trouble Code

<<See All OBD Codes

The trouble code P0AF3 can be explained as Drive Motor Inverter Temperature Sensor “B” Circuit Range/Performance Issue. This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle to another. The generator torque sensor is being monitored by the engine control module. This trouble code would be set by the ECM when the generator torque sensor would not be as per the specifications set by the manufacturer.

Do you want to know more about the P0AF3 fault code? Don’t worry! Parts Avatar Canada is here at your service. 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.

What causes this problem with the P0AF3 Drive Motor Inverter Temperature Sensor 'B' Circuit Range/Performance?

• Failed Inverter with Converter Assembly
• Open or short in the Inverter with Converter Assembly harness
• Poor electrical connections to Inverter with Converter Assembly circuit
• Faulty HV Control ECU

1. Engine Control Module - Dead cells in batteries can cause a failure in the engine control module. Many times, a battery is left in the rig long after a cell has died. This would affect the grounding in the car battery.
2. Powertrain Control Module - If there are some faults in the PCM, then it may throw off the timing and fuel settings of the engine, which can negatively affect the performance. A flawed PCM may cause the vehicle to experience a reduction in fuel efficiency, power as well as acceleration.
3. Electronic Control Unit - Do you know that the poor performance or unexplained drops in fuel economy or efficiency are often associated to onboard car computer problems, or defective ECU issues?
4. Diagnostic Tools - Use factory grade diagnostic tools to resolve OBD code P0AF3 error. Buy new diagnostic tools and equipment for us.
5. Motor Assembly - Faulty motor assembly can lead to erratic performance output and strange noises coming from under the hood. Thus, replace it immediately.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0AF3 code to be stored:

• The error code P0AF3 can be diagnosed using an OBD-II trouble code scanner.
• This scanner should be utilized in order to store the freeze frame data to collect the details of this error code P0AF3 by a certified mechanic.
• The mechanic should also check and confirm the presence of any additional codes.
• Now, if there are a number of codes, they should be aligned in order. It is essential to treat the codes in the order they have been stored in.
• After all the repairs have been performed, it is recommended to clear the codes and reset the system to observe if the code persists.
• Check for leakages in the intake manifold that may be leading to lean engine condition and thus hampering the performance.
• Also check for the motor temperature sensor circuit issue that might need replacement.
• If the code fails to reappear, it was likely due to an intermittent issue or was triggered falsely.

Common Mistakes When Diagnosing the P0AF3 Code

• Quirks in the powertrain control module
• Hybrid motor assembly or temperature sensor might start failing
• Fault in the oxygen sensor
• Problematic intake manifold system
• Wiring and connector related issues
