What P0E04 means
P0E04 is the general circuit code for the generator inverter's V-phase current sensor, meant for an electrical fault that is not narrowed down to offset, low or high. No manufacturer documents P0E04 publicly. Phase V is a special case: the 2018 Outlander PHEV measures generator current with only two sensors, on phases U and W (P0E01 to P0E03, P0E09 to P0E0B), since the third current follows arithmetically from the other two. Only the 2023 model adds its own V-phase sensor, and there its faults are reported solely through P0E05 to P0E07. CARB requires electrical monitoring of hybrid components that affect emissions. If the code does appear, check the inverter connectors and look for further phase sensor codes. Matching codes for phases U and W: P0E00 and P0E08.
P0E04 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor0.5 to 5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0E04
- Hybrid or engine warning light on
- Reduced generator output
Common causes of P0E04
- PossibleElectrical fault in the V-phase sensor circuit inside the inverter
- PossiblePoor contact at the inverter or generator control unit connector
- Less likelyGenerator control unit faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0E04 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 04 | The exact fault in that area. |
What to do next
- Note P0E04 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 P0E04
What does P0E04 mean?
P0E04 means "Generator Phase V Current Sensor Circuit". P0E04 is the general circuit code for the generator inverter's V-phase current sensor, meant for an electrical fault that is not narrowed down to offset, low or high. It is a generic code, so it means the same on every make.
Is it safe to drive with P0E04?
Drive gently and only to a workshop. With P0E04 the car can go into limp mode (reduced power) to protect itself.
Will P0E04 fail an emissions test?
Yes, it can. P0E04 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 P0E04 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 5 hours of work. This is a job for a workshop.
Will P0E04 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
