Hybrid/EV Battery Temperature Sensor G/H Correlation

Where it lives

For P0C87, the description names the sensor as the part involved.

Check these first

• Temperature sensor G or H reading outside the pack spread
• A faulty sensor G or H thermistor
• Corrosion in the sensor G or H connector
• High pack temperatures skewing one sensor
• A battery management system fault

What to do next

1. Read hybrid battery temperature sensors G and H on a scan tool
2. Compare the sensor G and H readings
3. Inspect the sensor G and H connectors for corrosion
4. Test the sensor G and H circuits
5. Replace the sensor that reads off from the pair
6. Clear the code and retest
