Generator Inverter Temperature Sensor A Circuit Low

Where it lives

For P0BCE, the circuit described runs through the sensor. The description of P0BCE reports a fault at the sensor.

Check these first

• A temperature sensor A reading below its normal range
• A short to ground in the sensor A circuit
• An open in the sensor A signal wire
• Low battery voltage affecting the circuit

What to do next

1. Read generator inverter temperature sensor A on a scan tool
2. Check battery voltage and charging
3. Test the sensor A circuit for a short to ground
4. Measure sensor A resistance cold and warm
5. Replace sensor A if it reads low across the range
6. Clear the code and retest
