P24C0EVAP System Leak Detection Pump Switching Valve Stuck On
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- P24C0 is a mechanical fault found during the leak test itself: the switching valve stays in its energised position, or the pump around it does not do its job. Mitsubishi's 2023 Outlander PHEV checks this when the parked car wakes its controller 5 h, 6 h or 8.5 h after shutdown. While the reference pressure is being measured, the canister pressure must fall at a set rate; if it drops too slowly or the pump cannot pull it down, the code sets after 1 s below the limit. Mitsubishi groups a stuck valve with a pump stuck on or off and a frozen sensor, all inside the ELCM, and asks to clear P24BE or P24BF first. Mitsubishi then disables canister purging and locks the filler flap. A valve stuck in rest position is P24C1.
