Installed a new icp and a turbo last week. Now I’m showing 7 codes after putting the truck back together.
I also noticed under full throttle my ipr goes up to 84.5 and I don’t remember it getting that high. Icp over 500 at idle and maxes out at 3000 I believe
Gotta love working on these trucks

Well, I think I fixed the problem. It was either in the butt joint splices where I had connected the aftermarket ICP pigtail connector last year, or the internal terminals of the connector itself.
I got my new Motorcraft ICP pigtail connector in Friday. I cut the old aftermarket connector off, and soldered on the new Motorcraft connector, and then heat shrinked the solder joints.
Over the weekend I put about 500 miles on the truck with the new pigtail ICP connector. The truck ran great, I didn't have a single issue.
Just another example of why it's better to spend the extra money up front on these trucks and buy the genuine Motrocraft part vs. the cheap aftermarket stuff.

|6literbeater||I forgot to mention the idle issue. Was going back and forth 100 rpm causing a surging and now I have what sounds like misses but diesels don’t miss so I have no idea yet. Hopefully we have the same issue. Icp looks good on the Scanguage though. Always above 500 on the start|

I’m having the same type of issue. Truck starts up in the morning fine and dandy but by the time I get to work the truck starts surging when I sit still in gear and out of gear. I was going to swap my icp for one from an 04 to see if this corrects the problem but I’m still in the research stage because I want to troubleshoot the issue first.
This weekend after getting sporty on the beach rescuing a quad and almost getting stuck myself I was bouncing around and a few wot’s I acquired another issue with my first crank no start and now my boost maxes out at 20 and I believe I have seen as high as 40 before this but I may be mistaken. I will swap my icp and update
Btw where did you get that icp from? The one I have came of a 200xxx plus mile truck that seized supposedly. It was free so that’s why I took it. I’ll be watching this thread

Thanks for the wiring diagram. I've driven the truck for 3 days now with the ICP unplugged....not a single issue. At this point, I think I found my problem.
My new Motorcraft pigtail should be in by this Saturday, I'll swap it out and see what happens.

|Hydro||Here is the engine wiring for that 05, maybe it will help chasing the wires|

|iqraceworks||It's an 05'|

|Hydro||What year is your truck? didn't see that at the start of this thread|

|iqraceworks||I did end up unplugging the ICP sensor on the truck before I drove it home from work. Not a single issue at all. I'm going to drive to tomorrow with the ICP unplugged again....if it doesn't act up, I'm going to say it's an ICP wiring issue.|

Yes the IPC should have been with the other readings -- and yes, if the connection is flakey, but not failed, it could act that way without setting a code
possibly a bad sensor, connector, or wiring up to the PCM -- have you checked the main harness connector? where the engine harness connects to the body harness -- intermittent troubles are very difficult to pin down
For sure you need to run the stock tune when troubleshooting a problem -- as you mentioned, some tunes mess with the warnings
