Going on hunting trip, towing trailer 2006 F350 SRW. Installed Spartans Econ. Tow. Started truck enginge bucked and idle flucuated for about 20 sec. then seemed fine. Took off this morning, about hour into the trip turbo goes out not turbo check engine light is on. Go back to stock tune, no turbo still, drive it a little turbo kicks back on then goes out again. Came back home 30 miles turbo worked fine the whole way back home, except turbo gauge didnt work.

Code I pulled

PO237 TRB Boost
S A Circ Lo In

Cleared code but keeps coming back.

Need some help guys

Thanks DB

 

It's a code for the MAP sensor. You might have a bad wire or hose off. I could only find a picture of what it looks like but no location: http://dan.prxy.org/Truck/6L_bible_h.../Page_063.html

If it's doing it with or without the tuner then it's probably NOT a tune problem, but give Matt a call anyway--he's very good at those kinds of problems. It would give your turbo fits.

 

i'm a little confused what you mean by : "turbo goes out not turbo check engine light is on"

also, can you tell me what you mean by "no turbo still, drive it a little turbo kicks back on then goes out again. Came back home 30 miles turbo worked fine the whole way back home"

turbos are a mechanical thing they either work, or they break. they do not "go out and come back on again" that would be an electrical thing, but once a turbo breaks, it broken until repaired. they do not TURN ON AND OFF ... please explain?

 

Maybe the turbo vanes are sticking...I hear if you drive it like a Grandpa they may stick no pun intended. I drive mine like I stole it.

 

do you have any other mods?
