DTC codes / P0Axx · Hybrid propulsion / P0AEB
P0AEB indicates that the hybrid or electric vehicle battery pack's temperature sensor D circuit is reporting a voltage higher than the manufacturer's expected range, which the battery energy control module interprets as an open circuit or a sensor signal that is out of bounds. The computer has detected a high-voltage condition on the signal line from sensor D, meaning the sensor is either disconnected, internally open, or the wiring has a break.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
