Hybrid/EV Battery Temperature Sensor E Circuit Range/Performance

Where it lives

For P0BC3, the description names the sensor as the part involved.

Check these first

• A sensor E reading outside the expected temperature range
• A drifting temperature sensor E
• High resistance in the E sensor lead
• A sensor E connector with poor contact
• A calibration fault in the E sensor channel

What to do next

1. Compare sensor E to the other pack sensors
2. Watch sensor E against ambient after a soak
3. Inspect the E sensor lead for added resistance
4. Check the E connector for corrosion
5. Replace sensor E if it reads implausible
6. Clear the code and retest
