'00 7.3 warm up valve problem

When I start my 7.3 in cold weather, a butterfly valve just after the turbo closes to hold exhaust gasses back to help with warming the engine up. After a few minutes, it opens back up. Once I start driving, it keeps closing. No matter how warm the engine is, the valve keeps closing. I have to give more throttle, or take my foot off the throttle. I can't figure out the problem. Any advise on what the problem is?

its closing once the truck reaches operating temp?
you can unplug the connector to the pedestal and that will make it stay open.

I made a mistake. I'm having problems with the EBP valve on the exhaust side of the turbo. It keeps activating no matter what the engine temperature is. If I give the engine throttle, or take my foot off the throttle it'll deactivate. Then it will activate again when I return to the desired engine speed. I looked at the exhaust manifolds and saw a rusted off pipe on the front of the passenger side manifold. I can't tell what the pipe goes to. I will appreciate any advise?

are you saying the up pipes or the ebpv tube to the ebpv sensor?

unplug the connector at the base of the turbo pedestal and this will cause the butterfly valve to stay open

I looked at pictures and found out that it's the small pipe that connects the EBP sensor to the front of the passenger side exhaust manifold. The pipe rusted off the manifold. It's an easy fix. I'll buy a new one.

I've never seen this advised as a fix.

OP: You can unplug the EBPV at the base of the turbo.
Also, that tube you see is the EBP sensor tube. Sensor is at the end of that. I wouldn't just unplug it, but fix it

I'll replace the tube and make sure everything else is working.
