Drive Motor B Phase V Current Sensor Circuit High

Where it lives

For P0BF8, the circuit described runs through the sensor. The description of P0BF8 reports a fault at the sensor.

Check these first

• A phase V current sensor reading above its normal range
• A short to voltage in the phase V sensor circuit
• A fault in the motor B phase V windings
• A weak battery or charge system shifting the voltage

What to do next

1. Read drive motor B phase V current on a scan tool
2. Test the phase V sensor circuit for a short to voltage
3. Check the motor B phase V windings for faults
4. Check battery voltage and charging
5. Replace the phase V current sensor if the circuit tests good
6. Clear the code and retest
