P0E08 covers an electrical fault of the generator inverter's W-phase current sensor that falls outside the offset, low and high categories. No manufacturer documents P0E08 publicly. Unlike phase V, the W-phase sensor exists on both Outlander PHEV generations Mitsubishi describes: the 2018 model uses it as current sensor 2, the 2023 model as one of three, yet both log its faults only as P0E09, P0E0A and P0E0B. CARB demands circuit monitoring of hybrid components relevant to emissions. A sensor that delivers no usable value at all keeps the inverter from controlling generator torque, so the system will typically cut generator power and rely more on the engine or the battery. Phase U counterpart: P0E00, phase V: P0E04.

Likely causes

Electrical fault in the W-phase sensor circuit inside the inverter
Loose or corroded connector at the power drive unit
Generator control unit faulty

Symptoms

  • Hybrid or engine warning light on
  • Reduced generator output, battery charged less while driving
