Drive Motor Inverter Temperature Sensor D Circuit High

Where it lives

For P0BD9, the sensor sits on the circuit this code reports. The description of P0BD9 reports a fault at the sensor.

Check these first

• A temperature sensor D reading above its normal range
• A drive motor inverter running hot under load
• Blocked airflow or a weak cooling system
• A short to voltage in the sensor D circuit

What to do next

1. Read drive motor inverter temperature sensor D on a scan tool
2. Check the inverter cooling fan and vents
3. Test the sensor D circuit for a short to voltage
4. Measure sensor D resistance against spec
5. Replace sensor D if the inverter is running cool
6. Clear the code and retest
