EMISSION CONTROL SYSTEM ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT FUEL CUT OPERATION


    1. Increase the engine speed to approximately 3500 rpm.

    2. A01W0AKE02

      *1 Fuel Injector Assembly
      *a Sound Scope

      Use a sound scope to check for injector operating sounds.

    3. When the accelerator pedal is fully released, check that injector operating sounds stop momentarily and then resume.

      Standard
      Item Specified Condition
      Fuel injection restart engine speed 1400 rpm

      If the result is not as specified, check the fuel injector assemblies, wire harness and ECM.

  2. VISUALLY CHECK HOSES, CONNECTIONS AND GASKETS


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

      Note


      • Detachment or other problems with the engine oil level dipstick, oil filler cap sub-assembly, ventilation hose or other components may cause the engine to run improperly.

      • Air suction caused by disconnections, looseness or cracks in any part of the air induction system between the throttle body with motor assembly and cylinder head sub-assembly will cause engine failure or engine malfunctions.

      If any defects are found, replace parts as necessary.

  3. INSPECT EVAPORATIVE EMISSION CONTROL SYSTEM


    1. Connect the GTS to the DLC3.

    2. A01W5H9

      Slide the clip and disconnect the fuel vapor feed hose assembly from the purge valve (purge VSV).

    3. Start the engine.

    4. Turn the GTS on.

    5. Enter the following menus: Powertrain / Engine / Active Test / Activate the EVAP Purge VSV.

    6. Check that vacuum occurs at the purge valve (purge VSV) port.

    7. If vacuum does not occur, check the following items:


      • Purge valve (purge VSV)

      • Clogging in the fuel vapor feed hose assembly that connects the intake manifold and purge valve (purge VSV)

      • Voltage from the ECM PRG terminal Click here

    8. Exit Active Test mode, connect the fuel vapor feed hose assembly to the purge valve (purge VSV) and slide the clip to secure it.

    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 valve (purge VSV) opens.

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