Hybrid/EV Battery Temperature Sensor C Circuit Range/Performance

Where it lives

For P0ACB, start at the sensor the description names.

Check these first

• A failed battery temperature sensor C
• Wiring or connector problems at the sensor C
• A sensor C that is out of calibration
• A hybrid battery pack fault

What to do next

1. Read battery temperature sensor C data on a scan tool
2. Compare the sensor reading to the pack temperature
3. Inspect the sensor C wiring and connectors
4. Assess the hybrid battery pack condition
5. Replace the sensor if the reading drifts
6. Clear the code and retest
