6.0 Problem

[06F350TD]

I got a 2006 Ford F350 King Ranch Dully, it has about 361,000miles.

I have had a problem ever since i bought this truck, couple months ago.


I cleaned out just about everything, EGR, EP, Changed MAP sensor, cleaned all the lines.

Couple problems:

The truck doesn't have enough power, it takes a long time to get up to 60(0-60)in about 13-15 seconds, feels like the truck is clogged up with something.
Once it did open up and it took around 10 seconds to get 60, it was working alright but not as it should work.
It does start shaking at 45mph-55mph.
I get it up to 24psi
I tried everything, i have a couple of codes that auto zone scanned for me.

Sorry about all the writing, but help will help me out a bunch thank you!


P0478- Exhaust pressure control valve high input, ECM has detected an error.

Probable cause
EGR system fault
Engine mechanical condition
Turbo fault condition

P0471- Exhuast pressure sensor range/performace
Faulty Ep sensor
Faulty ECM


P0299- Turbo charger under-boost

Faulty injector control pressure (ICP) sensor
EGR system fault .

That's about it Thanks guys!

not sure what it is. could be a lot of things, turbo, injectors ect..

361,000 miles is a lot, did you buy it new?

I bought it about 3 months ago, put about 1500 miles in it.

The Rpms go high to about 3,200 but the truck is not moving fast and it's not making a bawr sound if you know what i mean.

It sounds like the vanes are stuck in the turbo or maybe the cat is clogged causing a restriction? Are you getting the variable exhaust note from the truck when hitting the throttle from an idle? It should ramp up RPMs quickly and emmit an increasingly low to high pitch whistle. You need to check and make certain the hydraulic actuator on the turbo is cycling.

Turbo is stuck. Pull it apart and clean it

is it belching any smoke during the attempted accelerations? If it is belching black - its probably a coked EGR valve.

361,000 is alot of miles on a 6.0 - mind you they can take it when properly built (after built )

Or you could go based on the codes and clean the turbo. The vanes are stuck

I'm not sure what to do.

Clean the turbo the vanes are sticking

Had the same problem. Replaced the exhaust pressure sensor and it ran like it was new. It is located on the drivers side of the engine about 8 inches below the fuel bowl. You have to clean the tube that it is attached to. It runs into the front side of the exhaust manifold, it is usually completely junked up. If you try to clean the sensor, don't mess up the membrane in the sensor. I just bought a new one.


I was told it was the turbo, put on a new one and it did the same thing. Needed a new turbo but a 50.00 part would have fixed the problem.
Through the same codes you have.
Hope this helps
