P0E0E reports a generator phase line that reads high: one of the U, V or W connections is held near the positive high-voltage potential, typically by an upper power switch that stays on or by a short to the positive rail. No manufacturer documents P0E0E publicly; the generator units Mitsubishi describes for the Outlander PHEV only use P0E0C here, and in GM's tables only the open-phase check P0C05 is used for the corresponding drive motor group. CARB still requires circuit faults of hybrid components to be detected. Because a phase stuck high lets current flow without control, inverters normally shut the gate drive off at once; the generator then stops supplying charge and the vehicle runs with restricted hybrid function. Low and open counterparts: P0E0D, P0E0C.

Likely causes

Upper IGBT of one phase shorted or not switching off
Phase line shorted to the positive high-voltage rail
Phase monitoring in the inverter faulty

Symptoms

  • Hybrid system warning light and MIL on
  • Generator shut down, no charging while driving
