EMISSION CONTROL SYSTEM(w/o Canister Pump Module) ON-VEHICLE INSPECTION

PROCEDURE


  1. CHECK FUEL CUT-OFF RPM


    1. Put the engine in inspection mode Click here.

    2. Start and warm up the engine.

    3. Increase the engine speed to at least 2500 rpm.

      Note

      When checking the fuel cut rpm, the transmission should be in park.

    4. Use a sound scope to check for injector operating sounds.

    5. When the accelerator pedal is released, check that injector operating sounds stop momentarily (at 2500 rpm or higher) and then resume (at 1400 rpm).

      Standard
      Item Specified Condition
      Fuel cut off rpm 2500 rpm or higher
      Fuel injection restart rpm 1400 rpm

      If the result is not as specified, check the injectors, wiring and ECM.

  2. VISUALLY INSPECT HOSES, CONNECTIONS AND GASKETS


    1. Visually check that the hoses, connections and gaskets have no cracks, leaks or damage.

      Tech Tips

      Detachment or other problems with the engine oil dipstick, filler cap, ventilation hose and other components may cause the engine to run improperly.

      If any defects are found, replace parts as necessary.

  3. INSPECT EVAPORATIVE EMISSION CONTROL SYSTEM


    1. Put the engine in inspection mode Click here.

    2. Start the engine.

    3. A000RWE

      Disconnect the fuel vapor feed hose shown in the illustration.

    4. Connect the GTS to the DLC3.

    5. Turn the GTS on.

    6. Enter the following menus: Powertrain / Engine / Active Test / Activate the VSV for Evap Control.

    7. Check that vacuum occurs at the VSV port.

    8. Exit Active Test mode and reconnect the fuel vapor feed hose.

    9. Enter the following menus: Powertrain / Engine / Data List / EVAP Purge VSV.

    10. Warm up the engine and drive the vehicle.

    11. Confirm that the purge VSV opens.

      If the result is not as specified, replace the purge VSV, wire harness or ECM.

  4. CHECK HOSES AND CONNECTORS


    1. Visually check for loose connections, sharp bends or damage.
