P0E0C concerns the three power phases between generator inverter and generator, not the current sensors. The J2012 title fits the use Mitsubishi documents for the 2023 Outlander PHEV under its own label of generator current deviation: with at least 50 A commanded, the generator between 500 and 4,500 rpm and 8 V supply, a U, V or W current stuck within about 17 A either side of zero for 0.4 s, or a failed comparison with the target current, sets P0E0C-00 and the MIL. A phase that carries no current despite a demand is just what an open line looks like; GM checks drive motor phases in a similar way under P0C05. Likely causes are loose high-voltage terminals, a damaged phase cable or winding, or the inverter. Phase sensor faults are P0E00 to P0E0B.

Likely causes

Loose or burnt high-voltage phase terminal between inverter and generator

Phase cable or generator winding interrupted

Power drive unit does not drive one phase (switch or driver fault)

Symptoms

MIL and hybrid system warning light on
Generator no longer charges, engine runs without series hybrid support
Possible noise or vibration from the generator under load
