Name this piece, please
Part of living in the country is occasionally dealing with pack rats in my neck of the woods. I noticed a suspicious smell in my ventilation system, and sure enough, when I opened the glove compartment, there was evidence of rodent chewing, so I took apart the plenum under the wipers inside the hood, and sure enough I extracted a nest. As I was vacuuming up all of the stuff left by the pack rat, I noticed a little sensor that seemed to be formerly attached to a hose, with a wooden cap half eaten away and very fine wires inside, and a fine mesh screen in the nipple that attached the sensor to a hose. See the three very poor quality pictures I've attached for a little more detail.
Does anyone have an idea of what this is, where it went and how important it is to the car? My Fit is a 2013 model, standard transmission. If anyone knows this part, I'll be very impressed indeed! Thanks, everyone, now put on your thinking caps!
