Hybrid/EV Battery Temperature Sensor B Circuit Range/Performance

Where it lives

For P0AC6, the description names the sensor as the part involved.

Check these first

• A battery pack that runs too hot or too cold
• A failed battery temperature sensor B
• Wiring or connector problems at the sensor B
• A hybrid battery pack fault

What to do next

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