DTC codes / P0Dxx · Hybrid propulsion / P0DF3
P0DF3 indicates that the generator inverter temperature sensor C circuit is reporting intermittent or erratic signals to the control module. The computer detects this when the sensor's voltage or resistance readings jump unpredictably or drop out momentarily, rather than following a smooth, expected curve.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
