Codes Again!!!!
Well I have 2 codes today. P0299 and P0069. I noticed a slight lack of power when the lights came on. I had the p0299 code last week that I cleared. I did put a 4" turbo back exhaust on the truck. But the code last week came up before that happened. I warmed the truck up for 15 minutes this morning before I took it for a drive. The air temp was right around 0 degrees F this morning. I also picked up a scan gauge II.

Those numbers look excellent. Those two codes popping indicate a sensor bias. Check the numbers at 2500 rpm's also. Has the EGR valve been cleaned recently?

We bought truck 4 years ago and I havent cleaned the EGR valve since we bought it. We have put about 25k miles on it so it has just under 100k on it. Not sure what was done by the previous owner. We found the truck at a Honda dealer that had picked it up from an auction. We bought the truck dirt cheap and all we have done was batteries, ficm?, the turbo, and the new exhaust. It has been a good truck so far.

Another great DieselTechRon video:

Definately need to file this one away, P0299 code, surging idle and no throttle input; Bad ICP Sensor

My local dealer looked at the truck today. EGR sensor/ valve has failed. The tech cleaned it and it got worse. Should have the parts tomorrow and hopefully my truck back as well. Thanks for all the info everyone.

Same shop that misdiagnosed the Turbo??
I hope it works out cause the shop misses it one more time the gauge would been paid for
If it got worse that may mean he got fluid inside the egr valve during cleaning
With the truck off You should be able to unplug the egr valve and it should run better if the egr valve was the problem to begin with
theres a few things that the PCM Uses for egr valve position so if the valve was in wrong position then it could be something else

I am not sure they misdiagnosed the turbo. The truck has slightly different symptoms this time. This mechanic at the local dealership is supposed to be one of the best diesel mechanics around. However with what I have learned here I feel that I am gaining a lot of knowledge. The tech didn't know the egr valve could throw a 0299 code and kind of dismissed my suggestion based on info I was given here. I overheard him on the phone with Ford and at one point I heard "I thought that would trigger a 400 series code" which would be an EGR code. I am starting to have my doubts as well. The first thing I thought of when he said the valve got worse is he got fluid in the egr valve.
On a side note the EBP sensor was slightly dirty but the tube was clean. He never did check the MAP sensor or tube... But the numbers I got with my scan gauge were all within .5.
I am in a rural area and this dealer is less than a mile away. I wouldn't take my worst enemies truck to any of the other dealers in the area. There is a garage 15 miles away that does diesels but they are fairly new.

You might also look for leaks in the charge-air-cooler boots and tubes.
The P0299 can be SO MANY things. Having no real performance issues is a clue though. I suppose it could even be from the aftermarket turbo, but since yours did it BEFORE the powermax, I suspecta leak or a sensor issue to be more likely. The ICP sensor certainly could cause it, but you usually get rough running or surging with that issue.
You can clean out the things suggested pretty easily. The sensors are shown in the "2004 6.0L Coffee Table Book" if you are unsure of their location.

EDIT -
looks like the EBP and MAP sensors are shown in the 2003 Coffee Table Book. Just bear in mind that the EBP location for your truck will be slightly different.

As Mark said before, the P0299 can be caused by so many quirky things it's really hard to diagnose. The 400 codes can tell the tech of a failed valve electrically, etc but the failed valve can cause flow problems in the intake that the PCM can read as the 299 code. Hopefully that will at least get part of the problem solved.

Yes I do, but I'm wondering about the P0069 popping in there. It may go away though. I really don't see anything to cause it by the numbers you posted unless it's a freak from the extreme cold temps.

The day that code popped up the temp was around zero. I warmed the truck up for about 10 minutes. I didn't push the truck hard at all but the light came on when I was accelerating from a stop sign.

I experienced the P0299 code 20 to 30 times and just kept on erasing it. There was a grade I would climb that goes up 1,500 ft. In about 4/5 miles. The code came on so often that while I was climbing the grade I could tell when the code would set within a 100 yes of my position on the grade!!
Like I said, I replaced the STC fitting and the code never came back. My thoughts are while going up the grade the TPS, RPM, VSS were not meshing and the PCM was asking for more power but with the HPO leak the HPOP couldn't deliver the proper oil pressure to the Injectors to produce the proper power requested by the PCM.
Don't dismiss the the HPOP system out of hand just because it doesn't make sense. There's not too many things on these trucks that do make sense!!! At least post your HPOP numbers for the guys to look at (it's free) and at least remove that system from the list.
I agree with Benny, I think your Mechanic misdiagnosed the problem and you needlessly bought a new Turbo ( I have 200 K miles on my original Turbo).
Your on the right course now. Arm yourself with knowledge and use it. Just because someone has a blue oval on their shirt pocket doesn't mean they have the last word, You Do.
