Battery Charger A Input Voltage Sensor C Circuit

Where it lives

For P0EFB, the sensor sits on the circuit this code reports. The description of P0EFB reports a fault at the sensor.

Check these first

• An open or short in the charger A input voltage sensor C circuit
• A failed charger A input voltage sensor C
• A backed out pin at the sensor C connector
• Chafed wiring along the sensor C harness

What to do next

1. Read charger A input voltage sensor C on a scan tool
2. Test the sensor C circuit for open and short faults
3. Check the sensor C connector pins
4. Measure the sensor C resistance
5. Replace the charger A input voltage sensor C if faulty
6. Clear the code and retest
