Battery Charger Coupler Temperature Sensor C Circuit Range/Performance

Where it lives

For P2E4B, the description names the sensor as the part involved.

Check these first

• Charger coupler temperature sensor C out of range
• Heat at the charge coupler
• A failed coupler temperature sensor C
• A wiring fault on sensor C
• Corrosion at the coupler connector

What to do next

1. Read charger coupler temperature sensor C
2. Compare it to coupler temperature sensor A and B
3. Inspect the coupler connector
4. Test coupler temperature sensor C
5. Replace sensor C if the reading stays skewed
6. Clear the code and retest
