   INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY

   
   

   1. Connect the GTS to the DLC3.

   2. Start the engine.

   3. Turn the GTS on.

   4. Turn the A/C switch on.

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

      
      

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

         
         
         1. Powertrain > Engine > Active Test

            Tester Display
            Control the VVT Exhaust Linear (Bank1)

         2. 
            
            1.

            11. 
                

      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.

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

      
      

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

         
         
         1. Powertrain > Engine > Active Test

            Tester Display
            Control the VVT Exhaust Linear (Bank2)

         2.

            11. 
                

      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
