The map sensor is the one on the back of the engine block right behind your fuel filter canister. And the one that is lower and more towards the front is the datalink connector. Someone correct me if I am wrong.

what year? the mapp sensor and iat sensor is located on the intake behind the cansister. there's one behind the vp pump on 01 n 02 models and one behind the starter on 98-00 models. most likely the data link is what you're talking about. hooking up a comp?

A guy told me it was the map sensor so i was starting to hook up my smoke switch and hit It. And got smoke but now with the code cleared and all wirs pulled back out is still smokes when I hit It mmmm I think I made something lil mad?? How I found out where the map sensor was It was in the boost fooler paper work yup under intake. how do I fix what I did??

if its a 01 then the map senser is towards the front next to the vp pump
and for the smoke there might just be a bunch of carbon built up even w/ it stright piped mine did it for a lil while but it all depends on how long its been smoking like that to and hate to ask a dumb ? but did you say that you plug the map senser back in if not thats what the prob is

that's incorrect ^^^ the mapp is in the back of the intake, next to the iat sensor. the cam sensor is behind the vp pump. you usually have to remove the vp pump to replace the cam sensor.

so you plugged the smoke switch into the cam sensor plug?? I'm not sure they're the same style plug but the data link is 3 pins straight across ...iirc.. and the mapp is two small pins straight across... iirc. i'll look today and let you know.

this might help. the sensor down in front under the vp thats the one the guy told me was the map sensor. it has three wires a black - gray/purp - tan wire. thats the one i unpluged yes the truck will smoke when i hit the gas only at the hit then clears up. now it still smokes with no switch. didnt smoke before. yes it's plug back in. the sensor up top under intake has three wires one black one gray/red one orange. in the boost fooler papers for 01 its the map sensor? dont know way the one under the vp still makes truck smoke? i wander if when i hooked the switch up with the 10 ohm res. it killed the sensor? i only held it for short time. sorry for the book..lol

i'm not familiar with the smoke switch but guys have reported unplugging the mapp sensor to make more smoke. i'm not sure if you can run your smoke switch with the comp. ditch the smoke switch for now and just hook the comp up. the mapp sensor is the one on the intake not the one behind the vp. call cummins and order another cam sensor they're not real expensive. not sure if you killed it or not. getting any codes. ?? take truck back to stock and see if you get any codes or it still smokes.

p.s. proof read your posts.

Hello, new to all this, my vp44 went out and I ordered a rebuilt pump from Diesel specialists of Altamonte Fl. Box just showed up. Then I learned about this site and wish I had known about it earlier. My questions are-- is a rebuilt pump the way to go, will it last, and are there any places to avoid when buying one. I am also going to intall a FASS system at this time. This is a ,drive to work truck, and I don't do much heavy towing. Thanks
