Drive Motor Inverter Temperature Sensor E Circuit

Where it lives

For P0BDB, the circuit described runs through the sensor. The description of P0BDB reports a fault at the sensor.

Check these first

• A faulty inverter with converter assembly
• An open or short in the inverter temperature sensor E harness
• A poor electrical connection at the inverter temperature sensor connector
• A faulty HV control ECU

What to do next

1. Read the drive motor inverter temperature sensor E on a scan tool
2. Compare the inverter temperature with the coolant temperature
3. Inspect the inverter temperature sensor connector and harness
4. Test the temperature sensor E circuit for open and short faults
5. Replace the HV control ECU if the temperature signal stays wrong
6. Clear the code and retest
