P0E09Generator Phase W Current Sensor Circuit Range/Performance
- 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
- P0E09 is the zero-point check of the phase W current sensor in the generator inverter. Mitsubishi uses it on two Outlander PHEV generations. The 2018 code chart lists it as an offset fault of current sensor 2, the second of only two generator current sensors. For 2023 the generator control unit runs the same standstill test as for U and V: IGBTs off, generator under 20 rpm, at least 8 V supply, and the W-phase voltage has to stay inside 2.3 to 2.7 V; 0.32 s outside that band sets P0E09-00 and the MIL. On a two-sensor layout an offset in W also corrupts the V current derived from it, so control quality suffers on two phases at once. Hard signal faults of the same sensor are P0E0A and P0E0B.
- What you may notice
- MIL and hybrid system warning light on
- Rough or reduced generator operation
- Fault reappears at the next standstill check after clearing
- Likely causes
- LikelyZero point of the phase W current sensor drifted
- PossibleSensor supply or reference in the power drive unit unstable
- RareEvaluation in the generator control unit faulty
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
