Default What Sensor is This?

This sensor is under the hood on the passenger side of the car. I was in an accident, so this was hanging loose and I have no clue what it's function is. Anyone know? Thanks

It goes inside of the brake duct connected to the bumper. It's an ambient temp sensor for your heated washer nozzles.

Just for the washer nozzles. The ambient temp sensor for the OBC is in the drivers side brake duct.

aha ... one for each. god forbid we have one do both! so is the OBC one just a temp sensor and the one for the washers a thermoswitch (turning things on at a particular temp)?

yeah, it beeps as a freeze warning to tell you to watch out for potential icy conditions.

that was going to be my guess too. i think they default to some kooky temp like that when the temp sensor isn't connected or working.
