long story short my truck is throwing codes,, p1750, p0107, p0643, p0108, p0069. i do not have any downloaders stock except intake and exhaust, two weeks ago i threw A code 0069 and took it to dealer they replaced intake sensor problem went away 100 miles later i get this crap. all i did today was hook up a new egt guage but i didn't wire anything new just cut old wires and crimed new ones so just to make sure i unhooked the guage i put in and same thing i also shut the truck off on on about 10 times codes still there and I AM IN LIMP MODE. on top of that i leave for a 1000mile road trip with my trialer on tues. anyone have any advise way to fix anything?

 

It really seems like you have a short somewhere. Just glancing at the diagnostic testing in the service manual it seems like you have a wiring harness that is shorted to a ground and that is what is causing most of these codes. I would start checking your different ECM PCM plugs and using dielctical grease when you snap them back together. Then get those codes cleared. BullyDog, Edge, Smarty, and a few others have the ability to scan and clear codes.

Do you have access to anything that you can use to clear codes? Do you have access to a Service manual? Shoot me a PM and I might be able to post a copy of the service manual on my FTP server that you can access.

Check out the sticky post up top of forum.Seems alot of guys have found shorts that cause numerous codes. My bet is that you are one of the many!
My 03 has wire loom over all of the problem spots.Thats the way it came from factory.I guess the 2004.5 and up did not from what I have read.
Hope I helped.

 

What was the outcome of this problem? Any luck fixing it?
