PROCEDURE

1. 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 (for intake side).

      
      

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

         
         Powertrain > Engine > Active Test

         Tester Display
         Control the VVT Linear (Bank1)

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

         Standard Condition
         GTS Operation 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, wire harness and ECM.

   6. Inspect the camshaft timing oil control valve assembly (for exhaust side).

      
      

      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 using the GTS.

         Standard Condition
         GTS Operation 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, wire harness and ECM.
