What P0E0E means
P0E0E reports a generator phase line that reads high: one of the U, V or W connections is held near the positive high-voltage potential, typically by an upper power switch that stays on or by a short to the positive rail. No manufacturer documents P0E0E publicly; the generator units Mitsubishi describes for the Outlander PHEV only use P0E0C here, and in GM's tables only the open-phase check P0C05 is used for the corresponding drive motor group. CARB still requires circuit faults of hybrid components to be detected. Because a phase stuck high lets current flow without control, inverters normally shut the gate drive off at once; the generator then stops supplying charge and the vehicle runs with restricted hybrid function. Low and open counterparts: P0E0D, P0E0C.
P0E0E at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1 to 8 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0E0E
- Hybrid system warning light and MIL on
- Generator shut down, no charging while driving
Common causes of P0E0E
- PossibleUpper IGBT of one phase shorted or not switching off
- PossiblePhase line shorted to the positive high-voltage rail
- Less likelyPhase monitoring in the inverter faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0E0E means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 0E | The exact fault in that area. |
What to do next
- Note P0E0E 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 P0E0E
What does P0E0E mean?
P0E0E means "Generator Phase U-V-W Circuit High". P0E0E reports a generator phase line that reads high: one of the U, V or W connections is held near the positive high-voltage potential, typically by an upper power switch that stays on or by a short to the positive rail. It is a generic code, so it means the same on every make.
Is it safe to drive with P0E0E?
Drive gently and only to a workshop. With P0E0E the car can go into limp mode (reduced power) to protect itself.
Will P0E0E fail an emissions test?
Yes, it can. P0E0E 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 P0E0E to fix?
Difficulty: workshop only. A typical repair takes 1 to 8 hours of work. This is a job for a workshop.
Will P0E0E clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
