The P0C5A OBD-II code pertains to the Drive Motor “A” Position Sensor Circuit “B”. This code is triggered when the Motor Control Module detects an issue with the position sensor that reports the position of the drive motor output shaft.
What Does the P0C5A Code Mean?
The P0C5A code indicates that the Drive Motor Position Sensor is unable to provide accurate information regarding the position of the drive motor output shaft to the Motor Control Module. This can lead to poor vehicle performance and potential safety hazards.
What Causes the P0C5A Code?
The primary cause of the P0C5A code is a malfunction within the drive motor generator assembly. Specifically, if the Motor Control Module cannot accurately determine the output shaft’s position due to sensor failure, this code will be set. It’s important to note that the Drive Motor Position Sensor is integrated into the Drive Motor Generator and cannot be serviced separately.
What Are the Symptoms of the P0C5A Code?
- Reduced engine power
