Hybrid/EV Battery Temperature Sensor N Circuit High

Where it lives

For P0CB0, the sensor sits on the circuit this code reports. The description of P0CB0 reports a fault at the sensor.

Check these first

• An open in the sensor N signal or return
• A short to voltage on the sensor N wire
• A disconnected sensor N connector
• High resistance at the sensor N ground
• Overheating of the battery pack near sensor N

What to do next

1. Read hybrid battery temperature sensor N on a scan tool
2. Inspect the sensor N connector and wiring
3. Test the sensor N circuit for an open and a short to voltage
4. Measure the sensor N ground resistance
5. Replace sensor N if the reading stays high
6. Clear the code and retest
