Drive Motor Inverter Temperature Sensor G Circuit

Where it lives

For P0E23, the circuit described runs through the sensor. The description of P0E23 reports a fault at the sensor.

Check these first

• An open or shorted drive motor inverter temperature sensor G circuit
• A failed sensor G inside the drive motor inverter
• Corroded pins in the sensor G connector
• A broken wire between sensor G and the inverter control board

What to do next

1. Inspect the sensor G wiring for opens and shorts
2. Check the sensor G connector for corrosion
3. Measure the sensor G signal with the system powered
4. Compare the reading to ambient
5. Service the drive motor inverter if the sensor circuit does not recover
6. Clear the code and retest
