OBD II 0299 Code

[micpman]

I just bought a 2006 F350 with a 6.0L. After a day of Highway driving I stopped for the night. The next day I started the truck and the check engine light came on and the truck ran rough for about 5 miles then cleared up, but the check engine light stayed on. (Code was set)

I continued to keep an eye on the gauges and everything showed ok.

I finally got home and checked the codes, it came up as 0299 turbo/supercharger under boost.

Is this a common problem and what can I do to fix this?

If you are able to build boost most times, but are getting the code, it is likely sticky VGT. Time to clean turbo. Could also be leaky exhaust connections or torn boost boots. Check EBP and MAP sensors also.

MikeB,
Thanks for the reply.

Update on my trouble.

I cleared the code on Sunday and drove it Sunday and Monday with no code.

I checked the hoses for tears or leaks this morning, everything was ok.I drove to the parts store(Everything Still OK), When I left the parts store parking lot I noticed that it had set a code again. I did not notice what the boost reading was when the code was set. Im sure it was'nt much because I was not on the throttle very hard.

Both times the code was set was under very lite throttle conditions.

Under hard acceleration it shows a little over 20lbs of boost by the gauge in the dash, Is this about right or should it be more?

Forgot to mention that the truck has 127,000 miles

You should be able to get more boost than 20 at WOT. Codes don't always set immediately. You should read up on the common problems, get a scangauge or Insight. Still sounds like a sticky turbo. There are other possibilities, but that is a pretty easy project. If it has 120k and you haven't cleaned the turbo, it will not be wasted effort.

Thank you for the help.

Looks like I will be pulling the Turbo this weekend.
