EMISSION CONTROL SYSTEM ON-VEHICLE INSPECTION

CAUTION / NOTICE / HINT

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 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 leaks which may lead to an engine failure or engine malfunctions.

      If any defects are found, replace parts as necessary.

2. INSPECT EVAPORATIVE EMISSION CONTROL SYSTEM

   CAUTION:

   
   

   • 

     When working near the engine room while the engine has started or the power source mode is ignition switch to ON (IG), do not touch the fan and generator V belt or rotating components such as the fan, etc.

   • Touching the fan and generator V belt or rotating components such as the fan, etc. could result in your hand or clothing getting caught and pulled in.

   
   

   1. Connect the GTS to the DLC3.

   2. 

      Slide the clip and disconnect the No. 1 fuel vapor feed hose from the purge valve (purge VSV).

   3. Start the engine.

   4. Turn the GTS on.

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

      
      Powertrain > Engine > Active Test

      Tester Display
      Activate the EVAP Purge VSV

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

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

      
      

      • Purge valve (purge VSV)

      • Clogs in the fuel vapor feed hose connecting the intake manifold and purge valve (purge VSV)

      • Voltage at the ECM PRG terminal

   8. Exit Active Test mode, connect the No. 1 fuel vapor feed hose to the purge valve (purge VSV) and slide the clip to secure it.

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

      
      Powertrain > Engine > Data List

      Tester Display
      EVAP (Purge) VSV

   10. Warm up the engine and drive the vehicle.

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

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

3. INSPECT VENTILATION EJECTOR

   
   

   1. Remove the ventilation ejector from the cylinder head cover sub-assembly.

   2. 

      *a	Pin
      *b	Valve
      *c	Ventilation Ejector

      Check the operation of the valve.

      
      

      1. Insert the pin into the ventilation ejector hole and check that the valve moves smoothly.

         OK
         The valve moves smoothly.

         Tech Tips

         If the valve does not move smoothly, it may be stuck inside the ventilation ejector.

   3. Install the ventilation ejector to the cylinder head cover sub-assembly.
