I had my 05 F250 6.0 scanned today for a check engine light. Came up with 2 codes...P0299 & P2290. Does anyone know what they mean and what would make them come on? They were cleared out and the check engine light hasnt come back on yet. <!-- / message --><!-- BEGIN TEMPLATE: ad_showthread_firstpost_sig --><!-- END TEMPLATE: ad_showthread_firstpost_sig --><!-- sig -->
turbo underboost = ****ty day. if you have a scan tool that will monitor pids check your vgt percentage. if it drops really low (below 35%) at WOT than you have a sticking turbo. then you have to take it off, seperate it and clean the hell out of it and make sure your unison ring is still good.
the truck just made a 3000 mile trip across country. could it have just been a 1 time malfunction or do you think i have a major problem? No hard starts or surging.

Found this on another thread by one of our FTE Techs m-chan68
A P0299 Turbo Underboost code can set by numerous causes, namely a leak on the intake side between the turbo, charge air cooler and intake, a biased or improperly functioning EBP sensor, a leak on the exhaust side between the exhaust manifold and turbo up-pipe to the turbo, a restricted exhaust or restricted (plugged up) intake and a stuck VGT unison ring. Now your job is to pinpoint which of the above is causing the code to set.
On the oasis report on my truck has the same trouble code and here is what was done to repair it........Replaced EGR valve and ran VPS test remove turbo and check vanes, vanes was stuck had to replace char on turbo and tested ok.
