P0E0D is the low member of the generator phase circuit group: a U, V or W line between inverter and generator is pulled toward the negative high-voltage rail or to ground, for instance through damaged insulation or a lower power switch that conducts when it should not. No manufacturer documents P0E0D publicly. From this trio, Mitsubishi's generator unit in the Outlander PHEV only uses the open-circuit code P0E0C and catches dangerous currents with its own code P30A3; for the comparable drive motor trio GM's hybrid tables use only P0C05. CARB requires circuit monitoring of hybrid components. A low phase usually goes together with overcurrent or insulation warnings, so an insulation test of cable and winding belongs in the diagnosis. High counterpart: P0E0E.

Likely causes

Phase cable or winding insulation damaged, leakage to ground
Lower IGBT of one phase leaking or shorted
Phase voltage evaluation in the inverter faulty

Symptoms

  • Hybrid system warning light, possibly with insulation fault message
  • Generator shut down
