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 dipstick, oil filler cap sub-assembly, PCV 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 cylinder head sub-assembly will allow air suction and cause 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. A01HIML

      Slide the clamp and disconnect the fuel vapor feed hose assembly from the purge VSV.

    3. Start the engine.

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


      Powertrain > Engine > Active Test
      Tester Display
      Activate the EVAP Purge VSV

    5. Check that vacuum occurs at the purge VSV port.

      If vacuum does not occur, check the following items.


      • Purge VSV

      • Clogging in the fuel vapor feed hose connecting the intake manifold and purge VSV

      • Voltage at the ECM PRG terminal

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

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


      Powertrain > Engine > Data List
      Tester Display
      EVAP Purge VSV

    8. Warm up the engine and drive the vehicle.

    9. Confirm that the purge valve opens.

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

  3. INSPECT EJECTOR


    1. Slide the clamp and disconnect the No. 3 ventilation hose from the cylinder head cover sub-assembly.

    2. A01HIRNC02
      *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
        Valve moves smoothly

        Tech Tips

        If the result is not as specified, the valve may be stuck inside the ejector or there are problems sliding.

    3. Connect the No. 3 ventilation hose to the cylinder head cover sub-assembly and secure it with the clamp.
