ebpv valve info needed

[melmount]

I got my truck a few months back. I unplugged the ebpv valve.
I got codes p0470 p0475, i guess normal with it unplugged.
My question is though, how do i know if its open all the way and allowing flow? If it was not, what type of noise would it make? With the wires unplugged how do i know its(valve) is in the right position now?
I went to plug it back in tonite and noticed the 2 wires that go to it have no insulation on them they were bare. I found good wire about 1 inch from the loom with all the rest. I cut and capped them there, individually.
I have been searching for this growling type noise and was wondering if this could have anything to do with it.
I know its ok to have this unplugged but how do i know its not stuck half way or something?
thx
important, if its stuck what type of noise?

When closed it makes a whooshing exhaust brake kind of noise and your hp would be greatly reduced. Some guys tie them open with wire just for piece of mind.

is it the metal rod back there that gets tied? if i remember its like 6 or 8 inches long?

Yes a rod runs from actuator to the arm on the turbo.
