P0DF8 tells that temperature sensor C in the generator inverter delivers a voltage below its valid range. Mitsubishi uses the code in the Outlander PHEV for the W-phase high-side IGBT sensor: a reading at or under 1.25 V for 0.08 s, with at least 8 V GCU supply, stores P0DF8-00, and the check runs all the time. Physical causes are a short between signal and ground or a breakdown inside the module, for instance after coolant has reached the electronics. The value suggests a far too hot switch, so the controller derates the generator to stay on the safe side. The sensor cannot be replaced on its own, which is why Mitsubishi lists the power drive unit. The same fault on sensor B is P0DF5, the high case on this sensor P0DF9.

Likely causes

Signal line of sensor C shorted to ground

Shorted sensor or internal fault of the power drive unit

Coolant or moisture inside the inverter electronics

Symptoms

Hybrid or engine warning light on
Generator power limited
Implausibly high inverter temperature in live data
