Generator Position Sensor Circuit B High

Where it lives

For P0C6C, the circuit described runs through the sensor. The description of P0C6C reports a fault at the sensor.

Check these first

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

What to do next

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