Drive Motor A Phase U Current Sensor Circuit High

Where it lives

For P0BE8, the sensor sits on the circuit this code reports. The description of P0BE8 reports a fault at the sensor.

Check these first

• A phase U current sensor reading above its normal range
• High resistance in the drive motor A phase U windings
• A short in the motor A phase U windings
• A short to voltage in the sensor circuit

What to do next

1. Read drive motor A phase U current on a scan tool
2. Test the phase U sensor circuit for a short to voltage
3. Check the motor A phase U windings for shorts
4. Measure the phase U current sensor output against spec
5. Replace the phase U current sensor if the circuit tests good
6. Clear the code and retest
