P24187F Evaporative Emission System Switching Valve Control Circuit Actuator Stuck Off

DTC SUMMARY

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory Note
P24187F Evaporative Emission System Switching Valve Control Circuit Actuator Stuck Off

Following condition is met during key-off EVAP monitor:


  • EVAP pressure change when vent valve closed (on) less than 0.3 kPa (0.04 psi)

  • Canister pump module (reference orifice, leak detection pump, vent valve)

  • Connector/wire harness (Canister pump module - ECM)

  • Canister (filter inside canister clogged)

  • ECM

 Comes on DTC stored SAE Code: P2420
DTC No. Monitoring Item Detection Timing Detection Logic SAE Code
P24187F Vent valve stuck open (vent)

EVAP monitoring

(power switch off)

 2 trip P2420

Tech Tips

The vent valve is built into the canister pump module.

MONITOR DESCRIPTION

P24187F: Vent valve stuck open (vent)

In operation C, the vent valve turns on (closed) and the EVAP system pressure is then measured by the ECM using the canister pressure sensor to conduct an EVAP leak check. If the pressure does not increase when the vent valve is open, the ECM interprets this as the vent valve being stuck open. In this case the ECM will illuminate the MIL and store this DTC.

Frequency of Operation Once per driving cycle

CONFIRMATION DRIVING PATTERN

Note


  • The Evaporative System Check (Automatic Mode) consists of 9 steps performed automatically by the GTS. It takes a maximum of approximately 40 minutes.

  • Do not perform the Evaporative System Check when the fuel tank is more than 90% full because the cut-off valve may be closed, making the fuel tank leak check unavailable.

  • Do not start the engine during this operation.

  • When the temperature of the fuel is 35°C (95°F) or higher, a large amount of vapor will from and any check result will be inaccurate. When performing the Evaporative System Check, keep the fuel temperature less than 35°C (95°F).


  1. Connect the GTS to the DLC3.

  2. Turn the power switch on (IG).

  3. Turn the GTS on.

  4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

  5. Turn the power switch off and wait for at least 30 seconds.

  6. Turn the power switch on (IG).

  7. Turn the GTS on.

  8. Enter the following menus: Powertrain / Engine / Utility / Evaporative System Check / Automatic Mode.

  9. After the Evaporative System Check is completed, check for All Readiness by entering the following menus: Powertrain / Engine / Utility / All Readiness.

  10. Input the DTC: P24187F.

  11. Check the DTC judgment result.

    GTS Display Description
    NORMAL

    • DTC judgment completed

    • System normal
    ABNORMAL

    • DTC judgment completed

    • System abnormal
    INCOMPLETE

    • DTC judgment not completed

    • Perform driving pattern after confirming DTC enabling conditions
    N/A

    • Unable to perform DTC judgment

    • Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

    Tech Tips


    • If the judgment result is NORMAL, the system is normal.

    • If the judgment result is ABNORMAL, the system is malfunctioning.
