DTC codes / P0Exx · Hybrid propulsion / P0E29
P0E29 indicates that the drive motor inverter temperature sensor H circuit is reporting a range or performance fault, meaning the voltage signal from that sensor does not correlate with expected values under current operating conditions. The inverter controller compares the sensor's output against a plausibility model and flags this code when the signal stays out of bounds or behaves erratically.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
