so where do i get a map sensor without gettin rip by dealers? i keep gettin the p0237 gonna check the connections and grease hopefully that works but if not i wanna get one ordered.. thanks

 

have you checked your boots for leaks, had same code
put on new boots
cleaned map connections and cleared code hasn`t come back yet

 

MAP Sensor Mopar 05012801AA

Doesnt look like Cummins carries these. But, I would call Cummins before bending over and calling the dealership.

 

hmm put on custom tuning on adrenaline and soon as i plugged it back in there goes the cel

 

Cummins does carry the MAP sensors. I don't have the part# right here.

called dealership just to see how bad they wanted to bend me over and they said 2 different map sensors.

 

Yes, there is two different MAP sensors and the p/n I gave you is the one you need. The other one is for 2001/02 trucks and the p/n is: 5017791-AA
As already mentioned, take it out and clean it with some electrical contact cleaner.

Throwing parts at these things gets $$.

 

I've got the same problem. Need a boost sensor part no. 5083365ad
