Where it lives

For P0A42, the sensor sits on the circuit this code reports. The description of P0A42 reports a fault at the sensor.

Check these first

• A short to power in the drive motor A position sensor circuit
• An open in the sensor ground
• A drive motor A position sensor that reads high
• High voltage in the electrical system

What to do next

1. Read drive motor A position sensor voltage on a scan tool
2. Check the circuit for a short to power
3. Test the sensor ground
4. Check the electrical system voltage
5. Replace the sensor if the reading is fixed high
6. Clear the code and retest
