Hybrid/EV Battery Temperature Sensor K Circuit High

Where it lives

For P0C95, the sensor sits on the circuit this code reports. The description of P0C95 reports a fault at the sensor.

Check these first

• An open in the sensor K signal or return
• A short to voltage on the sensor K wire
• A disconnected sensor K connector
• High resistance at the sensor K ground
• Overcharging raising pack temperature near sensor K

What to do next

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