P24BFEVAP System Leak Detection Pump Switching Valve Control Circuit High
- Generic OBD-II code · Powertrain

- Matters for the ITP
- How the car detects it
- P24BF flags too much current in the switching valve circuit while the valve is energised. Mitsubishi's 2023 Outlander PHEV measures coil current through its low-side driver and sets the code when it reaches 2 A or more for 2 s with the valve commanded on. Such a value suggests a shorted coil or a control wire that touches battery voltage, so the driver is effectively feeding a dead short. The engine computer then blocks purge, keeps the fuel door locked and asks for a refuelling-system service. Check the wire between module and ECM for chafing before condemning the module, which carries pump, valve and sensor in one housing. The opposite electrical fault is P24BE; a valve that switches but does not seal is P24C0 or P24C1.
