Hi all, I am down to the last few errors in order to smog my new-to-me 2004 Cayenne S. I am getting a P2403 Evaporative System LDP Sense Circuit Open error. Poking around I found this hose to be loose, I can't seem to find it in any parts diagram, or evaporations system routing. Does anyone know what this hose is and where it should plug into? It comes from the back of the engine, but I can't see the exact point of connection there.



Red arrow points to end of loose hose.

 

Never mind, found it, I think it comes from the LDP, there's a spot on the back of the intake manifold for it to plug in to, next to 2 other ports.
