Ebpv Does Not Work!
does anyone know the criteria that the pcm needs to see to operate the EBPV?
oil temp? IAT? ECT?
12VDC 0r 5VDC?
possibly just a bad actuator but i would rather do the domplete diagnosis first.
looked in my mitchell on demand at work and could not locate a schematic or a flow chart for it though.
i disconected the valve rod and the butterfly moves freely, but it does not actuate no matter how cold it is.
i would also like to turn it into and exhaust brake once i get it working.

the ebp sensor is a variable capacitance sensor thats fed with 5 volts that produced a liniar analog voltage to indicate exaust back presure to control valve...

No, it isn't really needed for a proper warm up though as long as the actuator works you can still use it for warm up as well as a brake. When you exit the truck flip the switch so that when you remote start it will close (although the key still works fine.). You can get a ebpv sensor eliminator from DieselStop if you decide to just use it just for a brake so that a bad sensor doesn't defuel it like an overboost signal.
There are several lengthy posts on converting to a brake on this site and all are basically alike.
