Hybrid/EV Electronics Coolant Temperature Sensor A/B Correlation

Where it lives

For P2D2A, start at the sensor the description names.

Check these first

• Hybrid electronics coolant temperature sensor A and B disagreeing
• Air in the electronics coolant loop
• One electronics coolant temperature sensor drifting
• A wiring fault on sensor A or B
• A low electronics coolant level

What to do next

1. Compare electronics coolant temperature sensor A and B on a scan tool
2. Check the electronics coolant level and bleed air
3. Inspect the sensor A and B wiring
4. Measure each sensor resistance against temperature
5. Replace the drifting sensor
6. Clear the code and retest
