i believe that it is actually used to calculate your altitude or atmospheric pressure to change the fuel map. strange thing is that if you look down near the ecm on the passenger side and take that panel off there is another part that looks exactly like an atmospheric pressure sensor too, ill look it up for you and keep you updated.
