What is this part?

Hello and happy Monday. While replacing the radiator to cylinder head coolant hose I accidentally broke this piece shown in the pictures. I can't figure out what it is this I can't order a replacement. Maybe you can save me a trip to the dealer? It was attached where the red arrow is pointing. The actual electrical plug for this part is tucked out of view. Thanks.

 

Another angle.

 

I googled cylinder head temperature, water temperature, coolant temperature, and anti knock sensor and didn't come up with anything that looked like this. I have to go past the dealer anyway sometime in the next day or so.

 

Not that I can see but part of a bracket which MAY have one side of the sensor fell into the abyss so I'll be looking for that. I did notice that the sensor is set up for two wires but only one wire is used so I'm guessing some sort of heat sensor or thermocouple.

 

Thank you for that. I scoured those pages and didn't see anything that quite fits the bill. The one page that has arrows identifying different sensors in the engine bay seems to identify everything but the what looks like the one sensor I'm after. Great info though!

 

THANK YOU!!!! Unbelievable! My part (I recovered all of it) doesn't have a part number but looking at the schematic my best guess was an air conditioner condenser. Probably the same part and acts as a noise filter?

OK so I actually found another post but I'm new here and can't figure out how to link it. Patrick Wong was one of the people who commented. It's some sort of noise filter.
