Hybrid/EV Battery Temperature Sensor I Circuit Intermittent/Erratic

Where it lives

For P0C8C, the circuit described runs through the sensor. The description of P0C8C reports a fault at the sensor.

Check these first

• A loose sensor I connector
• Chafed sensor I wiring
• A sensor I thermistor breaking down when hot
• Water in the sensor I connector
• Electrical interference on the sensor I line

What to do next

1. Road test and watch hybrid battery temperature sensor I
2. Wiggle test the sensor I connector and harness
3. Heat the pack area and watch for a dropout
4. Inspect the sensor I wiring for chafing
5. Replace sensor I if the signal cuts out
6. Clear the code and retest
