DTC SUMMARY

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory Note
P24507E Evaporative Emission System Switching Valve Actuator Stuck On

Either of the following conditions is met when fuel tank pressure is between -2 and 3 kPa(gauge) [-0.3 and 0.4 psi(gauge)].


  • Fuel tank pressure change when vacuum introduction for canister is higher than 0.5 kPa (0.07 psi)

  • EVAP pressure when vacuum introduction for canister was complete is higher than (third reference pressure x 0.2)

  • Fuel vapor-containment valve

  • Connector/wire harness (fuel vapor-containment valve - ECM)

P24517F Evaporative Emission System Switching Valve Actuator Stuck Off

Either of the following conditions is met:


  • Fuel tank pressure change when vacuum introduction for canister is less than 0.5 kPa (0.07 psi)

  • EVAP pressure change when fuel vapor-containment valve is open is less than 0.9 kPa (0.1 psi)

  • Fuel vapor-containment valve

  • Connector/wire harness (fuel vapor-containment valve - ECM)

MONITOR DESCRIPTION


  1. P24507E: Fuel vapor-containment valve stuck open

    During sequence C, the leak detection pump creates vacuum in the EVAP system. If the pressure in the fuel tank drops, the ECM determines that the fuel vapor-containment valve is stuck open, illuminates the MIL and stores the DTC (2 trip detection logic).

  2. P24517F: Fuel vapor-containment valve stuck closed (vent)

    During sequence I, the fuel vapor-containment valve opens to allow atmospheric pressure into the fuel tank. If there is no change in fuel tank pressure, the ECM determines that the fuel vapor-containment valve is stuck closed, illuminates the MIL and stores the DTC (2 trip detection logic).

    During sequence G, the fuel vapor-containment valve opens to allow vacuum pressure generated by the leak detection pump into the fuel tank. If the pressure in the fuel tank does not drop, the ECM determines that the fuel vapor-containment valve is stuck closed, illuminates the MIL and stores the DTC (2 trip detection logic).

Fuel vapor-containment valve

Fuel tank pressure sensor

Canister pump module
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: P24507E or P24517F.

  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.
