P0A50Generator Position Sensor Circuit Overspeed
- 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
- P0A50 says the generator speed derived from its resolver has exceeded the permitted maximum. Mitsubishi documents it for the 2023 Outlander PHEV: with at least 8.0 V at the generator control unit and the position sensor itself judged healthy, a speed of 15,500 rpm or more lasting 0.5 s stores P0A50, and the repair path ends with replacing the generator. Because a resolver fault would already be caught by P0A4B to P0A4F, an overspeed entry usually reflects a real mechanical overspeed, for example from a transaxle or clutch problem, or an internal generator fault. The drive motor counterparts are P0A44 and P0A4A. CARB requires hybrid components to be monitored. Expect a hybrid warning and the generator being shut off to protect it.
- What you may notice
- Hybrid system warning and MIL
- Generator shut off, reduced power or engine-only drive
- Likely causes
- LikelyInternal generator fault (Mitsubishi repair path ends with generator replacement)
- PossibleMechanical fault in the transaxle or clutch letting the generator overrun
- RareIncorrect speed calculation in the power drive unit
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
