What P0E0A means
With P0E0A the phase W current sensor of the generator inverter reports a signal at or near zero volts. Mitsubishi covers this code in its Outlander PHEV service information: the 2018 chart attributes it to a short to ground or an open circuit of current sensor 2, and in the 2023 model the generator control unit sets P0E0A-00 after the W-phase voltage has stayed at 0.5 V or lower for 0.2 s with at least 8 V supply, lighting the MIL. On the 2018 two-sensor layout, losing phase W leaves a single measured phase, too little for current control, so generator operation is heavily restricted. Mitsubishi's procedure first deals with codes of higher priority, confirms the fault with a drive cycle and then replaces the power drive unit. Related: P0E09 and P0E0B.
P0E0A 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 P0E0A
- MIL and hybrid system warning light on
- Generator largely out of operation
- Battery is charged noticeably less while driving
Common causes of P0E0A
- Most likelyW-phase sensor signal shorted to ground or sensor failed low
- PossibleOpen sensor signal or supply 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 each part of P0E0A means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 0A | The exact fault in that area. |
What to do next
- Note P0E0A 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 P0E0A
What does P0E0A mean?
P0E0A means "Generator Phase W Current Sensor Circuit Low". With P0E0A the phase W current sensor of the generator inverter reports a signal at or near zero volts. It is a generic code, so it means the same on every make.
Is it safe to drive with P0E0A?
Drive gently and only to a workshop. With P0E0A the car can go into limp mode (reduced power) to protect itself.
Will P0E0A fail an emissions test?
Yes, it can. P0E0A 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 P0E0A to fix?
Difficulty: workshop only. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P0E0A clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
