What is this thing?

[Mohit]

I found this loosely hanging from the front end on the car on the drivers side. What is it?

Ambient Air Temp Sensor. It belongs behind the front valance.

Should I just leave it hanging there?

No, you should re-secure it. You shouldn't leave anything hanging, that's just asking for it to get torn off.

Okay, thanks!

At least, get it an athletic supporter or something...

Hey there, I also have something I can't identify and I hope it's ok to pin it here. It's hanging from the same general location (front driver-side under the valance) and I can't exactly follow the wires back to the fuse box or anything else. Thanks in advance!

Brake Lining Sensor Connector.

EDIT: Oops, I only read front drivers-side.

look under car at the brake airduct #5 in link you should find a hole in the side of the duct (if its there) that the outside temp sensor snaps into
