Help!, What is this light green sensor? Options

[joeladam02]

It's located right next to the EGR Valve. I believe it is supposed to have a vacuum hose coming from it, going to somewhere else as well. This is a 5sfe engine. I need to know what that sensor is so I can replace it. Obviously mine is effed. Any help appreciated.
Thanks!

Problem is, this arose in an engine swap. I was not there when the first engine was taken out, so I don't know what it was attached to. My brother did the work, and he doesn't remember. Luckily I was able to steal one off of my old motor that was warrantied because the parts store had not sent it back to the vendor yet. But I would still like to know what the hell it is, what it does, and why I can't find a new one anywhere I look. According to the vacuum diagrams it's a gas filter of some sort. Perhaps exhaust fumes?
