Front bumper off, unknown sensors hanging down

[Circa Surviven]

I hit an 18 wheeler tire in the road and my front bumper was damaged along with air duck and ac fan. Removing the bumper to assess the damage, I found two sensors on the driver's side that aren't attached to anything. One looks like it's possibly the outside air temp sensor? The other is a flat disk. One on the passenger side looks like it broke off something with the windshield wiper fluid leaking. Any help would be appreciated!

Your correct on both counts as to what the sensors are, if the connection on the wiper fluid res is damaged you could splice a junkyard connector as it isn't a very critical deal. If you want to fix it back to like new you will need to buy the connector and de-pin with those little de-pin keys like this:

Do you know where the driver side sensors are supposed to be stored/ located? I've watched YouTube videos and I haven't been able to see what bracket they sit in or if they loosely sit inside.

I'm thinking the driver side fender liner is broken and missing

Not sure about the "disc" but your outside air temp sensor is here:

Perfect, thank you! That whole piece of fender is gone now.

You'll need a left/right set of the ducts and possibly brackets/securing screws.

You can see the punch out where the “disc” sensor goes next to temp sensor

Aw, I wondered if there wasn't something under the brake duct, that's it. What is the "disc" sensor? Mine has the punch out still in place suggesting I do not have that sensor.

I think it has something to do with heated window washers but I’m not completely sure as to what or why I even think that. Do you have the headlight washers?

I have headlight washers and cold weather package fwiw.

Well, then it’s not that. Hopefully someone else knows and will chime in

When I googled the disc sensor part number it says "thermo switch for heated washer nozzle". I don't have nozzles on my bumper but it isn't the original. I wonder how you have nozzles but no disc sensor Cubieman ?

That I'm not sure, but I double checked and that sensor is definitely not present in the punch-out hole. If you look at my photo (of my car) you can see it's flat and the sensor is not there.

It could be zip tied or dangling behind the fender liner. If they were ever replaced, the sensor could have been overlooked
