    1. Connect a positive (+) battery lead to terminal 1 and a negative (-) lead to terminal 2, and check the movement of the valve.

      NOTICE:
      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.
