EMISSION CONTROL SYSTEM 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 assembly 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.

  2. INSPECT EVAPORATIVE EMISSION CONTROL SYSTEM


    1. Warm up the engine.

    2. Turn the power switch off.

    3. Connect the GTS to the DLC3.

    4. Remove the No. 1 engine cover sub-assembly.

      Slide the clip and disconnect the No. 2 fuel vapor feed hose from the purge valve (purge VSV).

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


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

    10. Check that vacuum occurs at the purge valve (purge VSV) port.

    11. If vacuum does not occur, check the following items.


      • Purge valve (purge VSV)

      • Clogging in the No. 2 fuel vapor feed hose that connects the intake manifold and purge valve (purge VSV).

      • Voltage from the ECM PRG terminal.

    12. Exit Active Test mode and reconnect the No. 2 fuel vapor feed hose to the purge valve (purge VSV) and slide the clip to secure it.

      Click here

    13. Enter the following menus: Powertrain / Engine / Data List / EVAP (Purge) VSV.


      Powertrain > Engine > Data List
      Tester Display
      EVAP (Purge) VSV

    14. Warm up the engine and drive the vehicle.

    15. Confirm that the purge valve (purge VSV) opens.

      If the purge valve (purge VSV) does not open, replace the purge valve (purge VSV), wire harness or ECM.

    16. Install the No. 1 engine cover sub-assembly.
