Since you've just completed some work on the car, I would pull the sensor and give it a good cleaning. I had the same thing happen after a coolant change. When I looked at the sensor it had some crud on it. After cleaning it really good, it was able to function again. Not a guaranteed fix, but I'd give that a try before buying a replacement.
