MONITOR DESCRIPTION

In sequence B and E, the leak detection pump creates negative pressure (vacuum) through the reference orifice. The EVAP system pressure is then measured by the ECM, using the canister pressure sensor, to determine the reference pressure. If the pressure detected meets one of the following conditions, the ECM will illuminated the MIL and store a DTC (2 trip detection logic).

MONITOR STRATEGY

Required Sensors/Components 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 higher 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: P043E00, P043F00, P24007E, P24007F or P24187E.

  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.
