Where it lives

For P0A4F, the sensor sits on the circuit this code reports. The description of P0A4F reports a fault at the sensor.

Check these first

• A generator position sensor connector losing contact
• Chafed wiring in the sensor harness
• Electrical interference on the sensor signal
• A weak high voltage battery affecting the sensor

What to do next

1. Road test and watch generator position sensor data
2. Wiggle test the sensor connector and harness
3. Check for electrical interference
4. Check the high voltage battery state
5. Replace the sensor if the signal drops
6. Clear the code and retest
