   NOTE:

   Confirm that the valve moves freely and does not stick in any position.

   If necessary, replace the camshaft timing oil control valve assembly.

   HINT: 

   Accumulation of foreign matter can cause minor pressure leaks. Minor pressure leaks will cause the camshaft to advance or retard, and this will cause a DTC to be set.
