2006 f450 6.0 diesel lost filter minder.After noticing no power and extreme black smoke we found filter minder missing.Replaced with oem part and new oem filter.Smoke setttled down but still to much boost only shows 10psi on factory gauge.No higher no matter how hard you are on throttle,HELP????????????

 

This probably isnt it but the only thing i can say is check the blue boot/hose going into the turbo on the left side of it. It might be almost off or loose, i know when they blow off you loose all power and boost. (its happened to us 5 times in 1 day til we got an aftermarket hose)

 

Do you hear the turbo spool, or a lot of air blowing from under the hood when you're on the throttle? If so, you have a boost leak like mentioned above. If not, sounds like you have a bigger problem. Maybe turbo locked up. Check all boost hose connections first.

 

Any smoke from under the hood? Had a similar issue. Everyone said blown Turbo and EGR. Including the dealer ship.

Found the exhaust pressure sensor had come loose, Found it by pure dumb luck too.
The EPS is a remote mounted sensor about halfway down the DS of the engine. The Copper sensing tube extends to a nipple a the DS front exhaust port. Mine has come undone, but still looked like it was in place due to the copper tube holding it in place, 10lbs of boost was enough to blow the tube away and and the turbo shut down, then would re-egage the turbo as long as I had less the 10 lbs. Smoked like a bugger also, I covered half my block with soot looking for this and had the sun blacked out for a while also.

Any ways this darling little sensor controls the vaines on the Turbo. No exhaust pressure = no turbo = pissed people with thier window down.

 

kinda what if hoping.opened up front side of turbo and the turbo spins free.What kinda money is this sensor?????

 

Couldn't tell you. Mechanic forgot to tighten the remote tube fitting all the way. Spun off after a couple months. simply tightened it back on.
