What P0E02 means
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.
P0E02 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1 to 5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0E02
- MIL and hybrid system warning light on
- Generator power limited or generator not used
- Battery charge falls faster in hybrid operation
Common causes of P0E02
- Most likelySensor signal shorted to ground or sensor output failed low
- PossibleOpen signal or supply connection of the sensor inside the power drive unit
- Less likelyInput stage of the generator control unit faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note P0E02 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0E02
What does P0E02 mean?
P0E02 means "Generator Phase U Current Sensor Circuit Low". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P0E02?
Drive gently and only to a workshop. With P0E02 the car can go into limp mode (reduced power) to protect itself.
Will P0E02 fail an emissions test?
Yes, it can. P0E02 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0E02 to fix?
Difficulty: workshop only. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P0E02 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
