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

PROCEDURE


  1. 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 sub-assembly, ventilation hose and other components may cause the engine to run improperly.

      • Disconnection, looseness or cracks in the parts of the air induction system between the throttle body with motor assembly and the cylinder head sub-assembly will allow air leaks which may lead to an engine failure or engine malfunctions.

      If the result is not as specified, replace parts as necessary.

  2. INSPECT EVAPORATIVE EMISSION CONTROL SYSTEM


    1. Connect the GTS to the DLC3.

    2. A01MUEE

      Slide the clip and disconnect the No. 1 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.


      Powertrain > Engine > Active Test
      Tester Display
      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 connecting the intake manifold and purge valve (purge VSV)

      • Voltage at the ECM PRG terminal

    8. Exit Active Test mode, connect the No. 1 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.


      Powertrain > Engine > Data List
      Tester Display
      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.

  3. INSPECT EJECTOR


    1. Slide the clip and disconnect the No. 3 ventilation hose from the ejector.

    2. A01MUZ7C01
      *a Pin
      *b Valve
      *c Ejector

      Check the valve operation.


      1. Insert the pin into the ejector hole and check that the valve moves smoothly.

        Standard
        The valve moves smoothly.

        Tech Tips

        If the valve does not move smoothly, it may be stuck inside the ejector.

    3. Connect the No. 3 ventilation hose to the ejector and slide the clip to secure it.
