PROCEDURE


  1. INSPECT FUEL CUT RPM


    1. Start the engine.

    2. Warm up the engine.

    3. Increase the engine speed to approximately 3000 rpm.

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

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

      Standard
      Item Specified Condition
      Fuel cut-off rpm 2500 rpm or higher
      Fuel injection restart rpm 1400 rpm

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

  2. VISUALLY CHECK 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, PCV hose 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.

  3. INSPECT EVAPORATIVE EMISSION CONTROL SYSTEM

    CAUTION:

    To prevent injury due to contact with an operating V-ribbed belt or cooling fan, keep your hands and clothing away from the V-ribbed belt and cooling fans when working in the engine compartment with the engine running or the power switch on (IG).


    1. Connect the GTS to the DLC3.

      Slide the clamp and disconnect the purge line hose 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.

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


      • Purge VSV

      • Clogging in the purge line hose that connects the intake air surge tank assembly and purge VSV.

      • Voltage from the ECM PRG terminal

    7. Exit Active Test mode and reconnect the purge line hose.

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


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

    9. Warm up the engine and drive the vehicle.

    10. Confirm that the purge VSV opens.

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