Generator Position Sensor Circuit A High

Where it lives

For P0C67, the circuit described runs through the sensor. The description of P0C67 reports a fault at the sensor.

Check these first

• A short to voltage in the generator position sensor A circuit
• High resistance at the sensor A ground
• A failed generator position sensor A
• Water in the sensor A connector
• A generator control module reading high on sensor A

What to do next

1. Read generator position sensor A voltage on a scan tool
2. Inspect the sensor A harness for a short to voltage
3. Measure the sensor A ground resistance
4. Test the sensor A signal with a meter
5. Replace the sensor if it is faulty
6. Clear the code and retest
