On this vehicle, there are two. If you look at pic 1, it shows their locations. I circled them.
As far as replacement, the intake needs to be removed. I attached the directions needed to replace them. Because you need to remove the intake, I would recommend replacing both. Make sure to get a good-quality sensor. You don't want to do it twice. LOL
Let me know if this helps or if you have other questions.
See pics below.
