What does code P0AEA mean?

Q: What does code P0AEA mean?

Hybrid/EV Battery Temperature Sensor D Circuit Low. P0AEA indicates that the hybrid or electric vehicle battery temperature sensor D circuit is reporting a voltage below the expected range, which the computer interprets as a low signal. This typically means the sensor's signal wire is shorted to ground or the sensor itself has failed, preventing accurate battery temperature monitoring.
