14 Volt Power Module Current Sensor A/B Correlation

Where it lives

For P0CC5, the part to look at first is the sensor named here.

Check these first

• Current sensor A and B disagreeing on the current
• A failed current sensor A or B
• Corrosion in the sensor A or B connector
• A wiring fault on one current sensor
• A 14 volt power module fault skewing one reading

What to do next

1. Read 14 volt power module current sensors A and B on a scan tool
2. Compare the sensor A and B readings against each other
3. Inspect the sensor A and B connectors
4. Test the sensor A and B circuits for opens and shorts
5. Replace the sensor that reads off from the pair
6. Clear the code and retest
