CAMSHAFT OIL CONTROL SOLENOID ON-VEHICLE INSPECTION

PROCEDURE

1. INSPECT CAMSHAFT TIMING OIL CONTROL SOLENOID ASSEMBLY

   
   

   1. Connect the GTS to the DLC3.

   2. Start the engine.

   3. Turn the GTS on.

   4. Inspect the camshaft timing oil control solenoid assembly (for intake side).

      
      

      1. Enter the following menus: Powertrain / Engine / Active Test / Control the Intake VVT OCV Duty Ratio Bank 1 or Control the Intake VVT OCV Duty Ratio Bank 2 / Data List / Intake VVT Change Angle Bank 1 or Intake VVT Change Angle Bank 2.

         
         Powertrain > Engine > Active Test

         Active Test Display
         Control the Intake VVT OCV Duty Ratio Bank 1

         Data List Display
         Intake VVT Change Angle Bank 1

         
         Powertrain > Engine > Active Test

         Active Test Display
         Control the Intake VVT OCV Duty Ratio Bank 2

         Data List Display
         Intake VVT Change Angle Bank 2

      2. Read the Data List while performing the Active Test with the engine idling.

         OK
         GTS Operation Data List (Intake VVT Change Angle Bank 1 or Intake VVT Change Angle Bank 2) -100% to 100% Varies by 70 DegFR or more

         If the result is not as specified, check the camshaft timing oil control solenoid assembly, wire harness and ECM.

   5. Inspect the camshaft timing oil control solenoid assembly (for exhaust side).

      
      

      1. Enter the following menus: Powertrain / Engine / Active Test / Control the Exhaust VVT OCV Duty Ratio Bank 1 or Control the Exhaust VVT OCV Duty Ratio Bank 2.

         
         Powertrain > Engine > Active Test

         Tester Display
         Control the Exhaust VVT OCV Duty Ratio Bank 1

         
         Powertrain > Engine > Active Test

         Tester Display
         Control the Exhaust VVT OCV Duty Ratio Bank 2

      2. Check the engine speed while operating the camshaft timing oil control solenoid assembly (for exhaust side) using the GTS.

         OK
         GTS Operation Engine Condition 0% Normal engine speed 100% Engine idles roughly or stalls
