Hybrid/EV Battery Pack Air Temperature Sensor A Circuit Range/Performance

Where it lives

For P0AAD, the part to look at first is the sensor named here.

Check these first

• A battery pack air temperature sensor A that reads out of range
• Corrosion at the sensor wiring or connectors
• A sensor that is out of calibration
• A battery pack cooling system fault

What to do next

1. Read battery pack air temperature sensor A data on a scan tool
2. Compare the sensor reading to ambient temperature
3. Inspect the sensor wiring and connectors
4. Check the battery pack cooling system
5. Replace the sensor if the reading drifts
6. Clear the code and retest
