I guess the new one works ok because it registered low when it blew out on the way to work this morning. Apparently I didn't do the retaining clip right. Are you supposed to push the sensor in and then put on the clip or push it in with the clip in place. I did it the first way and obviously it didn't work. I would be nice to be able to fix it before driving home today.

 

Oh well, I guess I can figure it out some way. At least it isn't far from home and I made it there ok.
