For what it's worth - if you do need to change the CHT sensor, I just did this.
Pain in the butt to get to. Had to go out to the garage 3x to find it, after looking at the forums here. Also might want to have one on hand before testing - as I had to cut the wires in order to remove mine.
Factory sensor is a 1-wire. I replaced with a 2-wire. They have different wrench flat dimensions. I had a deep well socket milled to allow the wires to clear while turning with a wrench - but unfortunately that socket was the wrong size to grab the old one. I had to cut wires to get the old one off - so no go on testing it afterwards.

If you'd like to borrow the socket (if it comes to that) let me know. I'm within an hour of you (or quick post office trip).
