How difficult is it to replace on my own?
I had to replace mine because it was spraying oil out of it.
It’s nopt too bad. You need to reach it from under the car. It’s installed below the intake manifold more on the drivers side of the car. You’ll have to jack the car up and get at it from underneath. There are 2 sensors there but I believe its the lower one you replace.
You shouldn’t have any problems…
Good luck
