I am trying to identify an air or vacuum hose that has come loose on my 2005 Pathfinder.
It is located on the driver side, the lower end is attached at the bottom of the engine, well below the oil dipstick. It is not a fluid hose, seems like an air or vacuum hose.
Trick is I cannot figure out where it should be connected to. I have search countless diagrams but cannot determine what hose it is...
Thanks for any help you can direct my way...
