Drive Motor A Position Sensor Circuit A Range/Performance

Where it lives

For P0C51, start at the sensor the description names.

Check these first

• A motor A position sensor A reading outside its normal range
• High resistance in the position sensor A circuit
• A position sensor A installed or calibrated wrong
• Electrical noise on the position sensor A signal

What to do next

1. Read motor A position sensor A on a scan tool
2. Compare the position sensor A reading to its expected value
3. Test the position sensor A circuit for added resistance
4. Check the position sensor A seating and calibration
5. Replace the position sensor A if it drifts off range
6. Clear the code and retest
