Drive Motor B Temperature Sensor Circuit High

Where it lives

For P0A33, the sensor sits on the circuit this code reports. The description of P0A33 reports a fault at the sensor.

Check these first

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

What to do next

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