P0E29Drive Motor Inverter Temperature Sensor H Circuit Range/Performance

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.
