P0DF5 sets when the signal voltage of generator inverter temperature sensor B stays below its valid window. Mitsubishi's Outlander PHEV checks this continuously: if the V-phase high-side IGBT sensor reads at most 1.25 V during 0.08 s while the generator control unit has at least 8 V supply, P0DF5-00 is stored. Mitsubishi does not say which temperature this means, but with a thermistor whose resistance falls as it warms, a low voltage looks like an extremely hot switch, the usual picture of a short to ground or a shorted element. The guided repair ends with a new power drive unit because the sensor is internal. Expect reduced generator power while the fault is present. The high case is P0DF6, an implausible in-range value P0DF4.

Likely causes

Signal line shorted to ground

Shorted thermistor inside the IGBT module

Internal fault of the power drive unit

Symptoms

Engine or hybrid warning light on
Generator output limited, engine runs more often
Displayed inverter temperature implausibly high
