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.
