I believe that it is a purge solenoid, but it is dark here and I have to check. The p1441 tells me that there is a vacuum leak past the purge solenoid to the evap line, which is a purge solnoid stuck open (malfunction or junk holding it open). It is normally mounted directly to the manifold close to the throttle body, but there are version that have the nylon line going to the manifold instead, with the purge solniod not far back. They are faily cheap so it may be worth replacing. It will have a nylon 6/6 quick connect hose on it. You have to push in on the release (hard) and pull back a little at the same time to release it.
