      Tech Tips

      
      

      • If the result is not as specified, allow the engine to cool (engine coolant temperature of 50°C (122°F) or less) and perform the Active Test again.

      • DTCs related to the VVT system may be stored due to Active Test operation, but this does not indicate a malfunction.

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