Error Code P0A31: What It Means & What To Do?

<<See All OBD Codes

The trouble code P0A31 can be explained as Drive Motor “B” Temperature Sensor 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 make 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 P0A31 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 Drive Motor "B" Temperature Sensor Circuit Range/Performance?

• Large vacuum leakage causing a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture
• IMRC actuator/sensor faulty
• A large air leak at or near the number one oxygen sensor would also cause a lean mixture

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0A31 code to be stored:

• The error code P0A31 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 P0A31 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 P0A31 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
