P0DF6 is the high-signal case for sensor B in the generator inverter. In the Outlander PHEV Mitsubishi stores P0DF6-00 when the V-phase high-side IGBT sensor voltage reaches at least 3.75 V during 0.08 s, again only with a GCU supply of at least 8 V. A voltage at the upper limit mostly points to an interrupted sensor line, a lost reference ground or a cracked element; with the common NTC layout it reads as an implausibly cold module. Since the inverter can then no longer protect its switches against overheating, the controller works with a safe substitute and may cut generator output. Mitsubishi's procedure ends with a new power drive unit. Too low a signal on this sensor is P0DF5; the same open-type fault on sensor C would be P0DF9.

Likely causes

Open signal line or backed-out terminal
Lost sensor reference ground
Cracked sensor element or internal fault of the power drive unit

Symptoms

  • Engine or hybrid warning light on
  • Inverter temperature shown far too low
  • Generator power reduced
