Generator Current Sensor Circuit High

Where it lives

For P0A5C, the sensor sits on the circuit this code reports. The description of P0A5C reports a fault at the sensor.

Check these first

• High resistance in the sensor wiring to the control module
• A generator current sensor reading high
• An alternator putting out excessive current
• A short in the charging circuit

What to do next

1. Read generator current sensor data on a scan tool
2. Test the sensor wiring for high resistance
3. Check alternator current output
4. Inspect the charging circuit for a short
5. Replace the sensor if the signal reads high
6. Clear the code and retest
