well i hooked up my EBPV to a toggle switch to use it as a break, i do have power through the wires and plug, i have hot and ground on plug, it doesn't close or click or nothing when i send power to it, with it running or not, any ideas guys??? thanks in advance

 

That's what I get when I don't look up the wiring diagram first before I open my pie-hole.

If you've already read the previous post, disregard that....I was WAY wrong.

 

i cut the (yellow with red?) i did not cut the black and white wire, and wired it to a switch, i do have a power and a ground, i used a test light to test both sides,

haha its alright

 

Wiring diagram says gray/red for PCM side signal (high side control ) wire.

 

ya gray/red that's why i had the question mark haha, so what could my problem be? if i try and pull the shaft coming from waste gate i can get it to move maybe 1/8 inch then it slides back into waste gate

 

Yea its just the red/grey wire thats at bottom of turbo. Cut and put your switch on the side going to the sensor and thats it.

 

ya i did that and nothing happens, it doesnt close no click, will it only close with it running and power sent to it, im trying to find out why it doesnt close when i send power to it,

 

You do realize that it is simply a valve that allows oil pressure to push against a piston, right?

It's NOT going to do anything without the engine running and supplying engine oil pressure to it.

You're not working with the wastegate here either (the rod on top of the turbocharger). You're working with the one near the downpipe on the bottom of the turbocharger underneath the turbine housing.

 

no sir i didn't, thats what im trying to figure out, so it works that way even with the pcm unhooked?

 

Yep. Without the engine running, there is no oil pressure to activate the exhaust backpressure valve in the turbo pedestal.

The engine won't run without the PCM so there won't be any oil pressure to activate the EBPV. You won't hear anything in the pedestal though just by switching power to it.
