What P24BE means
P24BE says the voltage on the switching valve control line is too low while the valve should be idle. Mitsubishi documents it for the 2023 Outlander PHEV: the valve sits in the ELCM leak check unit, is supplied by the MFI relay and grounded by a transistor in the engine computer, and the code sets when the line reads 3 V or less for 2 s with the valve not commanded. That pattern fits a missing relay supply, an open coil or a control wire shorted to ground. As a fail-safe the car stops purging, keeps the fuel filler door shut and shows a refuelling-system service message. P24BF is the over-current counterpart, P24BD the general circuit code; the related 0.020 inch leak test cannot finish meanwhile.
P24BE at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P24BE
- Malfunction indicator lamp on
- Fuel filler door does not open with the opener switch
- Refuelling system service message on the display
Common causes of P24BE
- Most likelyNo supply from the relay to the valve (fuse, relay, wire)
- PossibleSwitching valve coil open inside the module
- PossibleControl wire between module and ECM shorted to ground
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P24BE means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 4 | Area: auxiliary emission controls (catalytic converter, EGR, EVAP). |
| BE | The exact fault in that area. |
What to do next
- Note P24BE and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P24BE
What does P24BE mean?
P24BE means "EVAP System Leak Detection Pump Switching Valve Control Circuit Low". P24BE says the voltage on the switching valve control line is too low while the valve should be idle. It is a generic code, so it means the same on every make.
Is it safe to drive with P24BE?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P24BE fail an emissions test?
Yes, it can. P24BE is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P24BE to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P24BE clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
