P24BEEVAP System Leak Detection Pump Switching Valve Control Circuit Low

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
How the car detects it
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.
What you may notice
  • Malfunction indicator lamp on
  • Fuel filler door does not open with the opener switch
  • Refuelling system service message on the display
Likely causes
  • 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
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
