Drive Motor B Phase U-V-W Current Sensor Correlation

Where it lives

For P0BFE, start at the sensor the description names.

Check these first

• Phase U, V and W current readings that no longer agree
• One phase current sensor reading off the other two
• Wiring or corrosion in the phase sensor circuits
• A drive motor B fault skewing one phase

What to do next

1. Read drive motor B phase U, V and W current on a scan tool
2. Compare the three phase readings to each other
3. Inspect the phase sensor connectors for corrosion
4. Check drive motor B for a fault on one phase
5. Replace the phase current sensor that reads out of line
6. Clear the code and retest
