Camshaft Timing Oil Control Valve Assembly: Inspection

  1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY 
    1. Resistance inspection.
      1. Using an ohmmeter, measure the resistance between the terminals.

        Resistance: 

        6.9 to 7.9 Ω at 20°C (68°F) 

      If necessary, replace the camshaft oil control valve assembly.

    2. Movement inspection.
      1. Connect the positive (+) lead from the battery to terminal 1 and negative (-) lead to terminal 2, and check the movement of the valve.
    NOTE: Confirm that the valve moves freely and does not stick in any position.

    If necessary, replace the camshaft oil control valve assembly.

    HINT:

    Accumulation of foreign objects causes subtle pressure leaks. The subtle pressure leaks will cause the cam to advance, and this will cause a DTC to be set.
