Where Does This Tube Go To? Engine Question!

Recommended Posts


So yesterday I tackled my serpentine belt, I was driving a couple of days ago and then boom, lost power steering and noticed my belt was completely shredded, ordered the belt, two days later, replaced it myself and saved a lot of money.

While doing this, I noticed I am missing some tubing, and this is most likely why my CEL is on (P0441 If I remember the code correctly, which is a boost leak/vacuum leak most likely). When my belt snapped, I think it took out some tubing, and now I am missing the rest of the tubing and have checked the diagrams in the mechanic manual but haven't found anything.

Where does this tube go to? It comes off of the intake splitter y pipe and has a sensor connected to it early on in the tube. I have a 04 Cayenne Turbo, and in the picture I am pointing to it. Tube leads down near the serpentine belt keep in mind. Also, it's one of those bendable tubes as well.

Thanks a lot everyone for the help.
