There are very many sensore. You failed to say which one. Just because you have a code for a particular part, does not mean that is what is wrong. Your problem could be as easy as a vacuum leak. Even though there are many sensors i still recommend you to visit these site http://www.autosparepartsusa.com/searchparts.aspx?make=54&made=Escape&year=2005 ,i think you query gets solved here.
