If you unplugged the electrical connector at the bottom of the turbo pedistal, then a soft-code is normally set. However, this usually doesn't set off the SES light.
If you accidently unplugged anything else, then you could get an SES light. Check for any other loose connections. If it all checks out fine, then plug the connection for the EBPV back in and see if the light goes away. If it does, then your truck is one of few that sets the light off. If the light doesn't go away, scan for codes because you have a different problem.

Get it read to be sure, if it is related to disconnecting the EBPV it will be P0475, P0476, or P0478. www.puredieselpower.com sells a terminator for that plug so you dont throw a code.

Hey Alan, Im glad you got it disconnected and everything is running right. The SES I believe is coming on because you disconnected the EBPV. There is a cable that connects to the electrical that you disconnected, that tricks the PCM into reading normal so it wont throw a code at you. If I disconnect mine I will have to buy the cable. Here in NJ if your SES light is on when you go to inspection, you fail inspection. They actually hook up to the port and dyno vehicles here and your system has to read ready, if it says no info on there scan they know you cleared the codes while waiting in line. So let us know what you do. I was trying to find that cable, I saw it recently on here. Someone will have the link im sure

No, they will not read codes from our trucks. You need a scanner that is compatible with the Ford Powerstrokes. Autoenginuity is a popular choice. If you don't have access to a proper scanner, then take it to a diesel mechanic or the dealership.

I just wanted to say I appreciated all the information about EBPV. From all this information I was able to diagnose the problem with my truck. I was then determined to clean the tube. I easliy found the EBPV and the connections for the tube. I used two wrenches one to hold the top nut and one to loosen the connector. I gently loosened the top connection and found the tube was broke. Also, the tube was plugged. I realize cleaning it at this point is useless, but I have two questions. How do you reach that bottom connection? From underneath? And two I have been reading about disconnecting the EBPV using the terminator mentioned above, does this eliminate the EBPV leaving it open? Do I have to do anything with the lower end of the tube where it connects to the manifold? I might be okay with that. I doubt I'll ever use the EBPV for a brake. That seems like more than two questions, but thanks again for the information already posted.

bradley, to disconnect the epbv i just used a long flat screwdriver. if you are looking at the turbo from the drivers side, look the connection is right below the turbo, it is a 2 wire connector that is held together with a metal clip. just put he screwdriver under the botton of the clip and raise it up and it will snap off. then just pry the connect loose with the screwdriver and out if comes. mine through a code and believe it or not i went to advanced auto parts and their scanner read it right, ebpv malfunction or something like that. now my truck runs the way it used to. a lot of guys recommend buying the dfuser plug to plug the connection, i havent done that yet.

I will probably go with the dfuser. I had the electrical connection off when I was triing to clean the tube. I suppose I wouldn't have to worry about the lower connection of the tube at the manifold. It just seemed like a difficult place to work on if I needed to replace the tube or cap off the existing tube.
