P0C17 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P0C17 can be explained as Drive Motor "A" Position Sensor Not Learned. 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. This would also give rise to the illumination of the check engine light.

We believe that an investment in knowledge pays the best interest. So why not learn more about the P0C17 error code? The power inverter module is also known as the drive motor generator power inverter module. It has two motor control modules and the hybrid powertrain control module. Every motor control module works in its respective drive motor generator depending upon hybrid powertrain control module commands. The speed, direction and output torque of its respective drive motor generator is controlled by the motor control modules through the sequencing actuation of high current switching transistors called insulated gate bipolar transistors. Every drive motor generator work utilizing 3 phase AC. The insulated gate bipolar transistor works a single phase of the drive motor generator. Each and every phase is specifically identified as U, V and W.

What causes this problem with the Drive Motor "A" Position Sensor Not Learned?

• Some flaws in the drive motor
• Drive motor assembly harness is unlocked
• Drive motor assembly circuit might have inadequate electrical connection

1. Engine Control Module - ECM faults are rare but can be a big problem as faulty ECM will cause wrong vehicle operations and can also result in wrong OBD codes getting stored in the system which can also cause misdiagnosis. Thus, replace faulty ECM components now!
2. Powertrain Control Module - Check for PCM error which might be due to circuit faults that might require complete replacement and reprogramming. Replace it now!
3. Generator Assembly - If the generator assembly is faulty, it can cause many starting and charging issues. Any unresponsive generator assembly component can lead to inefficient functioning of drive motor and thus the motor performance. Replace faulty components today!
4. Motor Assembly - Are you experiencing a lot of vibrations while driving your car? In that case there are definitely some faults in your motor assembly. So, it is very important to replace the defective motor assembly with us at equitable prices.
5. Diagnostic Tools - Buy quality diagnostic tools to check and diagnose OBD code P0C17 error with the help of experienced mechanic. Visit us today! 

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 P0C17 here:

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.
• 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 drive motor “A” position sensor.
• If any of the component 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 P0C17 Code

• Non-performance of the drive motor generator power inverter
