Hey Guys!
I am stumped on this one. I would like y'all to help me narrow this one down a bit.
Here's my issue:
On my return trip from SC, I noticed that I am losing power while driving.
It goes like this:
1. From a dead stop, it seems to accelerate pretty good at about 50% throttle. Any more throttle than that and it makes absolutely no difference.
2. when cruising speed is achieved, if I go to pass someone or add more throttle to climb a grade, it seems like I almost have to mash the peddal all the way down! It downshifts fine, but very little additional power. Throws a little more smoke than usual but not too much. I can hear the turbo spool up ok with around 3-5% more throttle. (so I don't think it is the VGT)
3. fuel pressure and oil pressure good
4. cranks fine- no issues there
So, I stopped at rest area and pulled the dtcs. It threw P341 (camshaft sensor).
Here is what I have done so far to correct the issue:
1. Checked all CAC tubes, boots and connections
2. Obviously replaced the Camshaft sensor. - made no difference
3. Changed both fuel filters and drained water seperator- Made no difference
4. Went ahead and changed oil and filter while i was there.
I know there is an extensive list of possibilities. Here are a few of the ones i have come up with:
EBP sensor and line, tps, map sensor, potentiometer.
What do y'all think?
Anyone out there run across this same issue?
please list you thoughts in order of "most likely".

 

Did this just happen out of the blue? You said oil and fuel pressure is good right? What is your fuel pressure reading. A stock tuned 6.0 really shouldn't have ANY smoke. Being you have an 03, you don't have a boost gauge, but do you monitor boost at all? Me thinks the turbo just may not be allowing the vanes to open all the way.
