throwing a manifold absolute pressure sensor...Help?
How can i Fix this? what is the problem? it happens randomly......also my truck randomly goes into Regen with out the dpf and i dump white smoke.....COOL???

I have the same problem with my truck, I am beginning to think it is an Edge issue. I don't have an issue with the regen though.

http://www.cumminsforum.com/forum/6-7l-tech-articles/148888-cleaning-map-sensor-w-pics.html This is a must when doing the deletes. Once it's clean you should never have to clean it again after the egr delete is done. When it's dirty it leads to poor milage.

either upgrade your edge to the race if you dont have it or change your sims out for a 100 ohm resistor in the EGT plugs and you will never regen again

rbmedic, right now im running 330ohm resistors from RSD.....I should now get 100ohm resistors? instead?

Thanks for your help

the 330 should not allow you to regen but there is a possibility that one of them went bad they are only little 1/2 resistors normally. If you put a 100 ohm resistor in all of them or at least the front one it will never regen again (unless it burns out). In case your not familar what the sims do is tell the ECM that the exhasut is to hot to perform a safe regen ie we started out with 470 ohm and found them to be on the line so we went to 330 which are usually plenty but if your still going into regen then one went bad so 100 are the full proof and will stop a regen immediately. go to the tech 6.7 forum and look for the DIY delete on a budget follow those directions only use a 100 ohm 1/2 watt resistor instead of the 470 it list and you will be good to go.
