P0E0B marks a phase W current sensor signal in the generator inverter that sits at the top of its range. In the 2023 Outlander PHEV, Mitsubishi's generator control unit records P0E0B-00 when the W-phase voltage stays at no less than 4.5 V over a period of 0.2 s with a supply of at least 8 V, and turns on the MIL; the 2018 code chart names a short to the supply or a short circuit of current sensor 2. A value like this would match a current well above the generator's capability, so it is judged as a sensor fault, not as overcurrent, which Mitsubishi handles separately with P30A3. The code concerns the W-phase sensor alone; an open phase winding or cable shows up as P0E0C instead. Lower-limit and offset faults of this sensor: P0E0A and P0E09.

Likely causes

W-phase sensor signal shorted to its supply voltage
Current sensor in the power drive unit failed with high output
Lost sensor ground or reference inside the inverter

Symptoms

  • MIL and hybrid system warning light on
  • Generator switched off or limited
