P0AEA Hybrid/EV Battery Temperature Sensor D Circuit Low
The ECM detects a circuit low fault on the hybrid/ev battery temperature sensor d circuit. Reading cannot be used reliably for control.
Is it safe to drive with P0AEA?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
Common causes
- Most likelySignal wire shorted to ground
- PossibleInternal sensor short
- Less likelyConnector pins corroded - high contact resistance
Symptoms
- EV/hybrid system warning light on
- Reduced power output or limp mode
- Charging may fail or be slowed
- Reduced electric range
