P0DF7 is the plausibility code for temperature sensor C of the generator inverter. The idea behind it: after a long rest every power switch should be at roughly the same temperature, so a sensor that stands out is suspect. In Mitsubishi's Outlander PHEV the W-phase high-side sensor is compared once per trip, after 600 s or more of soak and with the IGBTs off, against the U- and V-phase sensors; a gap above 47 °C lasting 0.1 s stores P0DF7-00. The circuit itself is electrically fine in this case, so wiring checks rarely help, and Mitsubishi's procedure replaces the power drive unit. A genuine overheat of the inverter is reported separately as P0A3E. The same comparison on sensor B is P0DF4.

Likely causes

Sensor C drifted or stuck inside the IGBT module

Internal fault of the power drive unit

Control software misjudging the comparison

Symptoms

Engine warning light on after a cold start
Usually no noticeable change in driving
Possibly reduced generator power
