        If the result is not as specified, replace the camshaft timing oil control valve.

    2. Check the operation.
      1. Apply battery voltage across the terminals, and check that the spool valve operates.
        NOTE: Check that the spool valve is not stuck.

        HINT:

        The spool valve may not return if foreign objects are caught in it. This may cause subtle pressure leaks to the advance side, and a DTC may be set.
