EMISSION CONTROL SYSTEM ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT FUEL CUT RPM


    1. Start the engine.

    2. Warm up the engine.

    3. Increase the engine speed to approximately 3500 rpm.

    4. B0046XVC01
      *1 Fuel Injector Assembly
      *a Sound Scope

      Use a sound scope to check for injector operating sounds.

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

      Standard
      Item Specified Condition
      Fuel injection restart engine speed 1200 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.

      Note


      • Detachment or other problems with the engine oil level dipstick, oil filler cap 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. Start the engine.

    3. B00471U

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

    4. Turn the GTS on.

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

    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)

      • Clogs in the fuel vapor feed hose that connects the supercharger and purge valve (purge VSV)

      • Voltage from the ECM PRG terminal

    8. Exit Active Test mode.

    9. Connect the fuel vapor feed hose assembly to the purge valve (purge VSV) and slide the hose clip to secure it.

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

    11. Warm up the engine and drive the vehicle.

    12. 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.
