Hi and thanks for using 2CarPros.com

If the new sensor is not working, there is a chance you got a bad part. What I suggest is returning it and getting a replacement to see if it works.

If you have already done that, here are the removal and replacement directions specific to your vehicle. Also, the link I attached shows how it is done in general. See if you missed something. The attached pictures correlate with these directions.
