I need to find out what sensor this is.

The two hoses coming off of it go to the IACV. It has something to do with the coolant system, but Advance doesn't even have a sensor that matches it or that will fit. The top of the sensor where the harness connects to is broke. Any info on what sensor this is would be great. If you click on one of the pics to enlarge it, there are a few other pics of the sensor. Thanks

 

looks to me like a temp sensor. did it have 1 wire plug that goes to it?
what year make model is your car?
edit: 99 civic right? what trim (dx,ex,si,) auto/manual ?

 

Not sure how many wires it had, but the only connector I have left on the wire harness is a 2 wire connector. It's a EX Auto

 

i found it. its a air injection.

 

Thank you. I searched though the manual on the car, but couldn't figure out which part it was. I'm new to all of this and this is the first engine I have replaced. So, again thank you
