DTC codes / P0Axx · Hybrid propulsion / P0AEE
P0AEE indicates that the hybrid or electric vehicle's control module has detected an out-of-range or erratic signal from the temperature sensor that monitors the drive motor inverter, which is the power electronics unit that converts battery DC into the three-phase AC the traction motor needs. The computer compares the sensor's voltage against expected values for the current operating conditions and flags the circuit when the reading falls outside a calibrated window or behaves implausibly.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
