Motor Torque Sensor Circuit High

Where it lives

For P0A20, the sensor sits on the circuit this code reports. The description of P0A20 reports a fault at the sensor.

Check these first

• A short to power in the motor torque sensor circuit
• An open in the torque sensor ground
• A motor torque sensor that reads high
• A control module fault

What to do next

1. Read motor torque sensor voltage on a scan tool
2. Check the circuit for a short to power
3. Test the torque sensor ground
4. Inspect the torque sensor connector
5. Replace the sensor if the reading is fixed high
6. Clear the code and retest
