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

PROCEDURE


  1. CHECK FUEL CUT RPM


    1. A00YW3QC01
      *1 Sound Scope

      Start and warm up the engine.

    2. Increase the engine speed to at least 3500 rpm.

    3. Use a sound scope to check for injector operating sounds.

    4. When the accelerator pedal is released, check that injector operating sounds stop momentarily and then resume.

      If the result is not as specified, check the injectors, wiring and ECM.

      Standard
      Item Specified Condition
      Fuel injection restart rpm 1400 rpm

      Tech Tips

      Perform the inspection with the A/C off.

  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 dipstick, filler cap, 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 and cylinder head will allow air suction and cause an engine failure or engine malfunctions.

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

  3. INSPECT EVAPORATIVE EMISSION CONTROL SYSTEM


    1. Connect the GTS to the DLC3.

    2. A00YW3B

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

    3. Start the engine.

    4. 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

    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.

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


      Powertrain > Engine and ECT > 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.

  4. CHECK LINE AND CONNECTORS


    1. Visually check for loose connections, sharp bends or damage.

  5. CHECK FUEL TANK ASSEMBLY


    1. Visually check for deformation, cracks or fuel leakage.
