Drive Motor A Position Sensor Circuit C Range/Performance

Where it lives

For P0CDB, the description names the sensor as the part involved.

Check these first

• A sensor C winding whose output drifts with motor speed
• An air gap or runout problem at the sensor C target
• A worn sensor C bearing or tone ring
• Resistance in the sensor C wiring
• A motor control module misreading the sensor C signal

What to do next

1. Read drive motor A position sensor C data on a scan tool
2. Compare the sensor C signal across the motor speed range
3. Inspect the sensor C target for runout
4. Measure the sensor C circuit resistance
5. Replace the sensor if the signal drifts
6. Clear the code and retest
