The Map is on the back side of the intake horn, behind and below the EGR valve. I believe it uses 2- T10 Torx Screws to hold it in.
Flush it with some Brake Kleen and blow it out with some air.

It may be one of the resistors is not in right or is bad. Probably not in right. But we can't rule out the Map either.

These things with the emission systems are hard to trouble shoot anymore.

K2. . .Will the MAP cause the truck to act like it's in the Regen timer mode?

Not that it really matters, you will find out soon enough, only 1 screw.

Also, one time on the way home from the midwest, I had just filled up and got on the highway. Hit a bump from road construction and instantly got a lightning bolt. Kept cutting out and couldn't find the problem so I drove it all the way home like that. Brought it straight to the dealer and it was a camshaft position sensor. Also wouldn't start unless I cleard the code with my power pup. Just cranked over. So not sure what caused it. I think I have a thread on here about it.
