I don't know but look above it for a connection. It is probably a vacuum line for the HVAC system.

I can't find anything to plug it in to. I tried taking a picture but it kinda sucks of the area above where it's hanging


In this bottom picture, I see what looks like a vacuum nipple, just behind the steering column bracket, just to the left of the steering column, there is a electrical connection just ahead of it.

Today while driving the car's check engine light came on. The error message is P0442 EVAP Control System Small Leak, which I'm fairly certain is connected to this tube being loose. I just now connected it to the thing i believe Roewfast was speaking about, but I'm unsure if it's correct.


That hose would have gone to that part nipple and lye in a natural state if it belongs there. Do you know if there is vacuum on that hose under the dash? EVAP small leaks are hard to find. A smoke test is done on the system to find the leak.

I could possibly attach to a vacuum operated automatic park brake release switch. I don't know if they still had them in 2002, but all my 5.0L/5.8L models did.
