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 with motor body 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. Put the engine in inspection mode (maintenance mode)

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

    4. Start the engine.

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


      Powertrain > Engine and ECT > Active Test
      Tester Display
      Activate the VSV for Evap Control

    6. 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 from the ECM PRG terminal

    7. Exit Active Test mode and reconnect the fuel vapor feed hose to the purge VSV and slide the clamp to secure the hose.

    8. Enter the following menus: Powertrain / Engine and ECT / Data List / EVAP Purge VSV.


      Powertrain > Engine and ECT > Data List
      Tester Display
      EVAP Purge VSV

    9. Warm up the engine and drive the vehicle.

    10. Confirm that the purge valve opens.

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