CAMSHAFT OIL CONTROL VALVE ON-VEHICLE INSPECTION

PROCEDURE

1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY

   
   

   1. Connect the GTS to the DLC3.

   2. Turn the engine switch on (IG).

   3. Turn the GTS on.

   4. Inspect the camshaft timing oil control valve assembly LH.

      
      

      1. Enter the following menus: Powertrain / Engine / Active Test / Control the VVT Exhaust Linear (Bank1).

         
         Powertrain > Engine > Active Test

         Tester Display
         Control the VVT Exhaust Linear (Bank1)

      2. Check the engine speed while operating the camshaft timing oil control valve assembly LH using the GTS.

         Standard Condition
         Control Range Specified Condition 0% Normal engine speed 100% Engine idles roughly or stalls

         If the operation is not as specified, check the camshaft timing oil control valve assembly LH, wire harness and ECM.

   5. Inspect the camshaft timing oil control valve assembly RH.

      
      

      1. Enter the following menus: Powertrain / Engine / Active Test / Control the VVT Exhaust Linear (Bank2).

         
         Powertrain > Engine > Active Test

         Tester Display
         Control the VVT Exhaust Linear (Bank2)

      2. Check the engine speed while operating the camshaft timing oil control valve assembly RH using the GTS.

         Standard Condition
         Control Range Specified Condition 0% Normal engine speed 100% Engine idles roughly or stalls

         If the operation is not as specified, check the camshaft timing oil control valve assembly RH, wire harness and ECM.
