There must be something in the water considering all the turbo issues. Truck threw a P2262 (no turbo boost) code this morning on my way into LA. Checked hoses looked good with no other obvious causes. Truck is understandably sluugish but shows no other issues. Coolant/oil temps normal. Exhaust is normal. No strange noises.......etc.
Question is-I'm about 225 miles from home and safe haven. Should I chance the drive home as is or?
i would. even if you make it 100 miles it'll be cheaper than a 225 mile tow bill. it'll probably even get you home. sounds like the vanes in your turbo are stuck.
Well your clearly out of warranty range but you should be ok. Just keep an eye if anything starts to change. Your MPG is probably really low correct?
MPG is hard to tell at this time. Intial observation makes me think it's not too bad. I have been babying it though and not getting aggressive. Once up to speed I'm hardly in the throttle at all. Since it's all freeway I might be getting lucky in that regard.........
Well my question is you said it's understandably sluggish. So has it always been sluggish or did it just start when you noticed the code? Did the code set off the check engine light?
When I was pulling the grade this morning, before I realized there was an issue, I had to floor it for passing speed. That's what tipped me off. No CEL but my Hyperpac gave me the DTC. Truck was usually very responsive.
From a standing start the truck is sluugish is what I should have said...
I'll watch the guages and make sure it's all good as I go home. I'll let you know how it turns out.
Any thoughts on where turbo boost is monitored from?
Well very good news. Bismic you are partially correct. Intake leak......
It was the turbo boost sensor. Apparently the nipple had broken and disconnected from the intake manifold. Probably cracked when I was performing the EGR delete a couple weekends ago and then completely failed from the road vibrations etc. I also surmise that since this caused a DTC that the PCM went into safe mode and resulted in the loss of power rather than the turbo actually not functioning.
$101 dollars at Ford and I'm back in turbo boost.
Thanks for all the input.
(BTW this is my home personna-I'm jeklhyd at work)

Glad you got it worked out (and for a reasonable price as well). Also - thanks for posting the solution - I try to keep track of these things in my spreadsheet (but it is almost getting too big).
I know this is an old post but this happended to me today. Check engine light came on when I lost power. Some black smoke according to friend following me in car.
Stopped at Advance to get code checked and found out P2262 - turbo boost pressure not detected
I was only a few mile from my stop. 4 hours later, cranked it up and it ran just like normal. Plenty of power. 1.5 hr trip home on interstate 70-75 mph.
Any suggestions for sporatic situation?
BTW - E450 Ford shuttle bus. 2004, 6.0, only about 45000 miles.
Turbo replaced summer of 2008
The last E-Series I had that threw that code specifically was caused by the catalytic converter being restricted due to the internals coming apart. Something you can check yourself very quickly is to give it a tap from underneath. If you hear it rattling a little, that's your problem. Another thing you can try is disconnect the downpipe from the turbo temporarily, and drive it to see if full power is restored. These two tests will tell you very quickly whether or not the exhaust is restricted.
