Drive Motor A Phase W Current Sensor Circuit Low

Where it lives

For P0BEF, the sensor sits on the circuit this code reports. The description of P0BEF reports a fault at the sensor.

Check these first

• A phase W current sensor reading below its normal range
• Low battery voltage at the phase W circuit
• High resistance in the motor A phase W circuit
• A motor control module misreading the phase W signal

What to do next

1. Read drive motor A phase W current on a scan tool
2. Check battery voltage and charging
3. Test the phase W sensor circuit for a short to ground
4. Measure the phase W current sensor output against spec
5. Replace the phase W current sensor if it reads low
6. Clear the code and retest
