    2. Movement inspection.
      1. Connect the positive (+) lead from the battery to terminal 1 and the 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.
