Generator Position Sensor Circuit Low

Where it lives

For P0A4D, the sensor sits on the circuit this code reports. The description of P0A4D reports a fault at the sensor.

Check these first

• A short to ground in the generator position sensor circuit
• A generator position sensor that reads low
• Low battery voltage
• A control module fault

What to do next

1. Read generator position sensor voltage on a scan tool
2. Check the battery voltage
3. Check the circuit for a short to ground
4. Inspect the sensor connector
5. Replace the sensor if the low reading persists
6. Clear the code and retest
