Hybrid/EV Battery Temperature Sensor K Circuit

Where it lives

For P0C92, the circuit described runs through the sensor. The description of P0C92 reports a fault at the sensor.

Check these first

• A sensor K thermistor that reads off from the pack
• Corrosion in the sensor K connector
• A short or open in the sensor K signal wire
• A break in the sensor K ground wire
• A battery management system fault on the sensor K channel

What to do next

1. Read hybrid battery temperature sensor K on a scan tool
2. Compare sensor K against the other pack sensors
3. Inspect the sensor K connector for corrosion
4. Test the sensor K circuit for opens and shorts
5. Replace sensor K if its reading is off
6. Clear the code and retest
