P0E01Generator Phase U Current Sensor Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- 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.
- What you may notice
- MIL and hybrid system warning light on
- Generator output reduced, less charging while driving
- Code often returns after clearing at the next standstill check
- Likely causes
- LikelyZero point of the phase U current sensor drifted (sensor inside the power drive unit)
- PossibleUnstable sensor supply or reference voltage inside the inverter
- RareEvaluation circuit of the generator control unit faulty
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
