P0E03Generator Phase U Current Sensor Circuit High

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
  • Can trigger limp mode
How the car detects it
P0E03 is the upper-limit fault of the current sensor that measures phase U of the generator inverter: its signal is pinned near the supply rail. In the 2023 Outlander PHEV, Mitsubishi lets the generator control unit set P0E03-00 when the U-phase voltage climbs to at least 4.5 V and remains there for 0.2 s with the unit supplied by at least 8 V; for the 2018 model the code list blames a short to the supply or a shorted current sensor 1. A reading this high would mean a phase current far beyond anything the generator delivers, so the controller treats it as an electrical defect and not as overcurrent; genuine overcurrent has codes of its own, at Ford for instance P0A71. On the 2023 model the MIL is switched on as well. Low signal: P0E02, zero-point fault: P0E01.
What you may notice
  • MIL and hybrid system warning light on
  • Generator switched off or strongly limited
  • Engine runs more often without charging the battery
Likely causes
  • LikelySensor signal shorted to its supply voltage
  • PossibleCurrent sensor in the power drive unit failed with high output
  • RareLost sensor ground or reference inside the inverter
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
