Drive Motor B Phase U Current Sensor Circuit Range/Performance

Where it lives

For P0BF2, the part to look at first is the sensor named here.

Check these first

• A faulty hybrid vehicle motor assembly
• A phase U current sensor circuit fault on motor B
• An open or short in the motor B phase U current sensor wiring
• A poor electrical connection at the motor B current sensor connector

What to do next

1. Read the motor B phase U current on a scan tool
2. Compare the phase U current with the other motor phases
3. Inspect the motor B current sensor connector and wiring
4. Test the phase U current sensor circuit for open and short faults
5. Replace the hybrid vehicle motor assembly if the phase U reading stays out of range
6. Clear the code and retest
