What P0E8E means
P0E8E means the output of inverter voltage sensor B for drive motor A has fallen to the bottom end of its scale. On the 2023 Outlander PHEV Mitsubishi assigns it to the main measuring channel of capacitor 2 (V2M) in the power drive unit and sets it when that signal stays at no more than 0.45 V for 0.16 s, provided the unit has at least 8 V supply; monitoring runs continuously. Electrically this matches a short to ground, a broken signal path or a sensing circuit that has died, because the high-voltage bus itself would rarely read near zero while the system is active. The same channel reading high is P0E8F, while capacitor 1 on sensor A uses P0D2F for its low case. As the controller cannot trust the bus voltage, electric drive is limited or switched off and the MIL comes on.
P0E8E at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor0.5 to 6 hours
- Clears after repairAfter a drive cycle
Symptoms of P0E8E
- MIL and hybrid system warning
- Vehicle not ready to drive or only engine power available
Common causes of P0E8E
- Most likelyMeasuring circuit for capacitor 2 inside the power drive unit failed
- PossibleSignal line shorted to ground or open
- Less likelyNo high voltage on the bus because of a blown fuse or open contactor path
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0E8E means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 8E | The exact fault in that area. |
What to do next
- Note P0E8E 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 P0E8E
What does P0E8E mean?
P0E8E means "Drive Motor A Inverter Voltage Sensor B Circuit Low". P0E8E means the output of inverter voltage sensor B for drive motor A has fallen to the bottom end of its scale. It is a generic code, so it means the same on every make.
Is it safe to drive with P0E8E?
Drive gently and only to a workshop. With P0E8E the car can go into limp mode (reduced power) to protect itself.
Will P0E8E fail an emissions test?
Yes, it can. P0E8E 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 P0E8E to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 6 hours of work. This is a job for a workshop.
Will P0E8E clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
