So I my car started throwing a code for the cylinder head temperature sensor (2.0 zetec) and also the temp gage stopped working. When I went to replace the cht sensor I found that the wire was broken.
What I found out is that you can remove the connector from the end of the cht sensor and take it apart, strip the wires, and reinsert them back into the connector. I was very glad this worked out because I the only replacement part I could find was the whole wiring harness. The only thing is that you need to be careful about taking the plug apart so you don't break the connection pieces. In the end I got it back together and it is working fine :)
