Hybrid/EV Battery Pack “A” Cell Thickness Sensor Circuit Performance

Where it lives

For P2E6F, the description names the sensor as the part involved.

Check these first

• A failed cell thickness sensor in hybrid battery pack A
• A loose or corroded sensor connector on pack A
• A chafed sensor wire in the pack A harness
• Water or coolant intrusion at the pack A sensor
• A calibration fault in the pack A battery module

What to do next

1. Read the pack A cell thickness sensor data on a scan tool
2. Inspect the pack A sensor connector and harness
3. Test the pack A sensor circuit for open and short faults
4. Check for coolant or water at the pack A sensor
5. Replace the pack A cell thickness sensor if the circuit tests good
