None of the password managers I know allow for online checking of password expiration. As you can guess this is implemented differently on each website so it would be very hard to implement.
That said, a couple of password managers do present some functionality that may facilitate this task for you:
KeePass 2 supports expiration time for its password entries. It also supports Triggers and Scripting, which all together open up interesting possibilities; like automatically opening the associated website when the entry on KeePass expires.
RoboForm integrates with your browser(s) and allows for quick creation, editing and deletion of its password entries through its browser toolbar.
