Drive Motor Inverter Temperature Sensor D Circuit Low

Where it lives

For P0BD8, the circuit described runs through the sensor. The description of P0BD8 reports a fault at the sensor.

Check these first

• A temperature sensor D reading below its normal range
• A short to ground in the sensor D circuit
• An open in the sensor D signal wire
• An inverter control module misreading the signal

What to do next

1. Read drive motor inverter temperature sensor D on a scan tool
2. Test the sensor D circuit for a short to ground
3. Measure sensor D resistance cold and warm
4. Check the inverter control module for updates
5. Replace sensor D if it reads low across the range
6. Clear the code and retest
