Bought the part, got under the car, and can't figure out how to get a wrench on the old sensor to remove it.

Anyone know what kind of tool can be used to do this? Looks like about a 22mm fitting.

 

Okay, just in case anyone cares... I was able to get a 22mm deep socket on it after cutting the wire. Putting the new one in has been a challenge, it's barely more than finger tight right now, still looking for an open end wrench that might fit so I can snug
it down more.

Another update for anyone who searches for this problem in the future - Autozone has the rental part. It's a combination of a deep socket with a slot in the side for the wire to pass through, and the other parts are offset sockets (with the same slots) that you can put a rachet on.
Wish I had gone in there first!
