EMISSION CONTROL SYSTEM ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT FUEL CUT OPERATION

    CAUTION:


    • When working near the engine room while the engine has started or the power source mode is ignition switch to ON (IG), do not touch the fan and generator V belt or rotating components such as the fan, etc.

    • Touching the fan and generator V belt or rotating components such as the fan, etc. could result in your hand or clothing getting caught and pulled in.

    A004AW3

    1. Start the engine.

    2. Warm up the engine.

    3. Increase the engine speed to approximately 3500 rpm.

    4. A004AKOC02
      *1 Fuel Injector Assembly
      *a Sound Scope

      Use a sound scope to check for fuel injector assembly operating sounds.

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

      Standard (for CVT)
      Item Condition Specified Condition
      Fuel injection restart engine speed A/C OFF 1200 rpm
      A/C ON 1500 rpm
      Standard (for Manual Transaxle)
      Item Condition Specified Condition
      Fuel injection restart engine speed A/C OFF 850 rpm
      A/C ON 1500 rpm

  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

    CAUTION:


    • When working near the engine room while the engine has started or the power source mode is ignition switch to ON (IG), do not touch the fan and generator V belt or rotating components such as the fan, etc.

    • Touching the fan and generator V belt or rotating components such as the fan, etc. could result in your hand or clothing getting caught and pulled in.

    A004AW3

    1. Connect the GTS to the DLC3.

    2. Start the engine.

    3. A0048JA

      Slide the hose clip and disconnect the No. 1 fuel vapor feed hose from the purge valve (purge VSV).

    4. Turn the GTS on.

    5. Enter the following menus: Powertrain / Engine and ECT / 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)

      • Clogging in the vacuum hose that connects the intake manifold and purge valve (purge VSV)

      • Voltage from the ECM PRG terminal

    8. Exit Active Test mode.

    9. Connect the No. 1 fuel vapor feed hose to the purge valve (purge VSV) and slide the hose clip to secure it.

    10. Enter the following menus: Powertrain / Engine and ECT / 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.
