Where it lives

For P0C5A, the sensor sits on the circuit this code reports. The description of P0C5A reports a fault at the sensor.

Check these first

• An open or short in the drive motor A position sensor B wiring
• A failed position sensor B winding inside the motor
• Corroded or backed out pins at the sensor B connector
• Chafing in the resolver cable run to sensor B
• A motor control module fault on the sensor B channel

What to do next

1. Read drive motor A position sensor B data on a scan tool
2. Inspect the sensor B connector and pins
3. Test the sensor B circuit for an open and for a short
4. Measure the sensor B winding resistance
5. Replace the sensor if the winding is off spec
6. Clear the code and retest
