Hybrid/EV Battery Temperature Sensor D Circuit

Where it lives

For P0AE8, the circuit described runs through the sensor. The description of P0AE8 reports a fault at the sensor.

Check these first

• An open or short in the battery temperature sensor D circuit
• A failed hybrid battery temperature sensor D
• Corrosion or water in the sensor D connector
• A control module that cannot read sensor D

What to do next

1. Read battery temperature sensor D voltage on a scan tool
2. Check the sensor D circuit for an open or short
3. Measure the sensor D resistance against temperature
4. Inspect the sensor D connector for corrosion or water
5. Replace sensor D if the circuit tests good
6. Clear the code and retest
