Hello! I'm new here and drive a 2015 jeep compass high altitude (and love it!). I recently had my check engine light come on and when I got diagnostic work done on it they told me I had a bad fuel tank pressure sensor. They said they would order the part on August 20th and now they're telling me they "can't find the part". My fiance is pretty handy with anything automotive so I asked him for help. He can't find this part either. My question is: does this part exist and if so how do I go about replacing it on my own?
