since everyone calls it a map sensor, i went to autozone to get a price on one cause i thought i needed one. turns out mine was fine but thats not the issue.
the guy at the counter said diesels didnt have a map sensor then proceded to tell me that there is no manifold pressure and thats why they dont have map sensors.
i guess my boost guage is just for looks right.
i just started laughing and walked out............then i went to napa and tryed to have them look up a price for me.
same thing they said no map on diesel.
what gives
maye we should shouldnt call it a map sensor any more....lol

 

That is what it is. Manifold Air Pressure. Check out this link for part number:https://commcenter.insightbb.com/att...wnload_php.htm
You should learn not to trust the guys at Auto parts stores. If you want real info, come here or go to Cummins.

 

yeah i agree the auto parts stores don't know what they are talkin about.

 

Dealer also told me the truck doesn't have a MAP sensor, but it has a boost sensor.
