With P0E0A the phase W current sensor of the generator inverter reports a signal at or near zero volts. Mitsubishi covers this code in its Outlander PHEV service information: the 2018 chart attributes it to a short to ground or an open circuit of current sensor 2, and in the 2023 model the generator control unit sets P0E0A-00 after the W-phase voltage has stayed at 0.5 V or lower for 0.2 s with at least 8 V supply, lighting the MIL. On the 2018 two-sensor layout, losing phase W leaves a single measured phase, too little for current control, so generator operation is heavily restricted. Mitsubishi's procedure first deals with codes of higher priority, confirms the fault with a drive cycle and then replaces the power drive unit. Related: P0E09 and P0E0B.

Likely causes

W-phase sensor signal shorted to ground or sensor failed low
Open sensor signal or supply inside the power drive unit
Input stage of the generator control unit faulty

Symptoms

  • MIL and hybrid system warning light on
  • Generator largely out of operation
  • Battery is charged noticeably less while driving
