Caravan check engine code PO441
Check engine light on, took it to Advance Auto and their meter says code PO441, checked lines all appear ok, changed gas cap about a year ago , so not thinking it is that. Appears to be some gas in the white plastic piece ( don't know what it is called) that connects hose from cannister to hose from gas tank. Unable to get it apart and don't want to break it, any one know how to remove? Wonder if anyone knows where I might find a diagram of the emission system? Also, is it ok to drive van this way? I need to drive 600 miles this weekend. Thanks for your help
