2007 6.0 6 speed, 187,000 miles. The other day started truck, had been running about 20 minutes before. Started fine, go to drive, chugging white smoke, smelled like unburbt diesel, baby truck home, seemed to run ok at low rpm, truck warmed up and ran fine. But I also noticed turbo boost was acting funny. Truck ran fine next few days. Then this morning, started cold fine, started to drive it and same chugging white smoke, it quit by the time j got to the end of my driveway, but drove to work, it quit smoking, ran pretty smooth, but will not build any boost. Truck is bone stock except for exhaust, it's straight piped. Ok. So this eve I borrowed my dads edge cts, here's all the engine codes
P0069
P0269
P0299
P2262
P2269

The last one is water in fuel, since it started this crap I did notice it was right after it came on in the dash

I'm trying to figure out where to start
Thanks for any help you can give

On another note. VGT duty shows 85% at idle ?
Ficm voltage is constant 48 volts
Newer batteries

 

Could these codes all be from one problem? I also check for pressure coming out of oil cap. None

 

should not see 85% all the time at idle.
turbo might be sticking causing a rich condition.
check back with MAP, EBP and BARO numbers at KOEO and idle.

 

Hate to sound like a dumbas$ but what is KOEO?
What all data do I need?

 

no worries lol KOEO = key on, engine off
not sure what you need to input into the CTS as i have never used one.
im sure someone can chime in on that

 

Key on Engine off

 

KOEO
Vgt 0.0
Maf 0.0
Ficm 47.5-48
Baro pressure 14.3
Exhaust back pressure 4

At idle
Vgt 40.5
Maf 36-37.0
Ficm 48
Baro pressure 14.3
Exhaust back pressure 4

 

looks like you need an EBP sensor.
you can try cleaning it, and the tube it threads into. might save a few bucks
also need MAP #s
they should all be close to each other.

although i have seen edge devices act weird with the EBP readings. not 100% on that.

 

Yep I got one or two of those codes with a bad EBP. Also map, baro, and ebp should be within a point or so koeo. Clean the map hose, ebp tube, and egr valve. Worse casr the will be a turbo pull and clean.

 

That is at engine idle. I pulled map hose. Cleaned the port out. Took it out. Ran pretty good. It at least builds boost again

 

awesome. clean the ebp next if you can. that might fix you all the way up

 

What about the cylinder 3? When I bought the truck it ran funny cold and threw a cylinder 4 unbalance?

 

Also. Water in fuel code? Have anything to do with all the codes?

 

have you drained the separator since it came on? takes a 6mm alen key.
be careful not to strip it.

also did the cylinder 4 go away? and just have cylinder 3?
hopefully some fresh t6 oil and maybe some archoil or Rev x.
personally I've used Rev x and had 2 balance codes go away in about 300 miles. they eventually came back but it got me about 8 extra months out of them.

 

Yea. After I bought it. I changed oil to t6. Added rev x. After around 500 miles or so it quit throwing cylinder 4 code. I also changed fuel filters. That was 1500 miles ago
