P0E8EDrive Motor A Inverter Voltage Sensor B Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- 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.
- What you may notice
- MIL and hybrid system warning
- Vehicle not ready to drive or only engine power available
- Likely causes
- LikelyMeasuring circuit for capacitor 2 inside the power drive unit failed
- PossibleSignal line shorted to ground or open
- RareNo high voltage on the bus because of a blown fuse or open contactor path
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
