Generator Position Sensor Circuit B

Where it lives

For P0C69, the circuit described runs through the sensor. The description of P0C69 reports a fault at the sensor.

Check these first

• An open or short in the generator position sensor B circuit
• A failed generator position sensor B
• Corroded pins at the sensor B connector
• Water intrusion into the sensor B connector
• A poor sensor B ground

What to do next

1. Read generator position sensor B data on a scan tool
2. Inspect the sensor B connector for corrosion
3. Test the sensor B circuit for an open and a short
4. Measure the sensor B resistance
5. Replace the sensor if it is open or shorted
6. Clear the code and retest
