Drive Motor Inverter Temperature Sensor A Circuit High

Where it lives

For P0AF0, the sensor sits on the circuit this code reports. The description of P0AF0 reports a fault at the sensor.

Check these first

• An open in the inverter sensor A circuit
• A failed inverter temperature sensor A reading high
• Corrosion in the sensor A connector
• A drive motor inverter that is overheating

What to do next

1. Read inverter temperature sensor A voltage on a scan tool
2. Check the sensor A circuit for an open
3. Measure the sensor A resistance against temperature
4. Check the inverter cooling for a blockage
5. Replace sensor A if the circuit tests good
6. Clear the code and retest
