P0E02 is stored when the output of the generator inverter's phase U current sensor falls to the bottom of its range, a level no real current would produce. Mitsubishi uses it on the Outlander PHEV: from model year 2023 the generator control unit, supplied with at least 8 V, sets P0E02-00 once the U-phase signal drops to 0.5 V or lower and stays there for 0.2 s; unlike the zero-point test, no standstill is needed. The 2018 code chart describes the same code as a ground short or a broken line at current sensor 1. Because the sensor is built into the power drive unit, Mitsubishi's procedure ends with replacing that unit after a confirming drive cycle. The offset check is P0E01, the opposite fault P0E03. Without a valid U-phase value the generator usually runs only in a limited way.

Likely causes

Sensor signal shorted to ground or sensor output failed low
Open signal or supply connection of the sensor inside the power drive unit
Input stage of the generator control unit faulty

Symptoms

  • MIL and hybrid system warning light on
  • Generator power limited or generator not used
  • Battery charge falls faster in hybrid operation
