Conversation Between FalxZZR and btwice

hey just saw you on here so i thought i would ask a quick question that i thought you might know. my fi light came on and its showing 2 code. which is the map sensor. i located the map sensor. and was wondering if the little prong on the bottom is suppose to have a hose going to it? or its just suppose to be with no hose but just the clip. i hope this isnt confusing
