P0E01 flags an implausible zero point of the U-phase current sensor inside the generator inverter. Sensors of this kind put out a voltage near the middle of their span while no current flows, so the test is only run when the machine cannot carry current. Mitsubishi documents the code for the Outlander PHEV: on the 2023 model the generator control unit evaluates the U-phase signal with the IGBTs switched off, the generator turning below 20 rpm and at least 8 V supply, and stores P0E01-00 if the value leaves the 2.3 to 2.7 V band for 0.32 s; MIL and hybrid warning light come on. The 2018 code chart calls the same code an offset fault of current sensor 1. A shifted zero distorts generator torque control. Hard signal faults of this sensor appear as P0E02 or P0E03.

Likely causes

Zero point of the phase U current sensor drifted (sensor inside the power drive unit)
Unstable sensor supply or reference voltage inside the inverter
Evaluation circuit of the generator control unit faulty

Symptoms

  • MIL and hybrid system warning light on
  • Generator output reduced, less charging while driving
  • Code often returns after clearing at the next standstill check
