What P0E00 means
P0E00 is the general circuit code for the current sensor in phase U of the generator. Each phase sensor, usually a Hall-type device inside the inverter, outputs a voltage around a mid-point when no current flows. No manufacturer documents P0E00 publicly. Mitsubishi's Outlander PHEV shows how its generator unit judges the U-phase sensor: at standstill below 20 rpm with the IGBTs off the signal must stay between 2.3 and 2.7 V (P0E01-00 after 0.32 s), and readings of 0.5 V and lower, or 4.5 V and higher, held for 0.2 s set P0E02-00 or P0E03-00. P0E00 is meant for circuit faults outside these categories. Without the signal the inverter cannot regulate generator torque properly. Phases V and W are P0E04 and P0E08.
P0E00 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 P0E00
- Hybrid system warning and engine warning light
- Generator switched off, reduced performance
- Vehicle may not reach ready mode
Common causes of P0E00
- PossibleSupply or reference fault of the current sensor
- PossibleDefective phase U current sensor inside the inverter
- Less likelyFaulty internal connection between sensor and control board
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0E00 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 00 | The exact fault in that area. |
What to do next
- Note P0E00 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 P0E00
What does P0E00 mean?
P0E00 means "Generator Phase U Current Sensor Circuit". P0E00 is the general circuit code for the current sensor in phase U of the generator. It is a generic code, so it means the same on every make.
Is it safe to drive with P0E00?
Drive gently and only to a workshop. With P0E00 the car can go into limp mode (reduced power) to protect itself.
Will P0E00 fail an emissions test?
Yes, it can. P0E00 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 P0E00 to fix?
Difficulty: workshop only. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P0E00 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
