Drive Motor Inverter Temperature Sensor A Circuit Low

Where it lives

For P0AEF, the circuit described runs through the sensor. The description of P0AEF reports a fault at the sensor.

Check these first

• A short to ground in the inverter sensor A circuit
• A failed inverter temperature sensor A reading low
• Corrosion in the sensor A connector
• A control module pulling the sensor A signal low

What to do next

1. Read inverter temperature sensor A voltage on a scan tool
2. Check the sensor A circuit for a short to ground
3. Measure the sensor A resistance against temperature
4. Inspect the sensor A connector for corrosion
5. Replace sensor A if the circuit tests good
6. Clear the code and retest
