Map sensors

samedi 23 août 2014

My sons 4.0 now has a 1600 rpm idle, yea , just a little high. I pulled the codes and map sensor came up as open circut. Being I'm an " old guy " I had to do a little reading on what these little sensors did. What I don't understand is if they sense load on the engine, and at idle there is no load, why is the idle so high !?!?
