When faced with a job that cannot be done easily, you have to look at what is in the way preventing you from getting to that part.
If the easiest path for you is removing the entire intake manifold assembly, Buy a service manual that shows you step by step removal and replacement procedures for these parts that are blocking your access and work according to the manual.
For many years on more cars than I can remember I had no choice but to work on remove and replace parts that I could only feel with the tips of my fingers.
If your going to be the one maintaining and fixing your car, you have to take the good with the bad, Jobs like this force you to get creative make or customize tools to get the job done.
Going from the bottom side is the best and fastest way to change this sensor,
For your sake I hope this sensor is bad and you diagnosed it properly and are not just hanging a part on the car for no reason.
once your calmed down and not all pissed off at the world about YOUR problem, raise the car up on 4 jack stands as high as you can safely get it.
Then calmly look at the parts that are preventing you from getting to this sensor.
Is the axle getting in the way? or is it the tie rod end on the rack, perhaps the sway bar is keeping you from getting that few extra inches where your comfort level goes up.
removing parts from above like the intake manifold is just not a good idea if you have no idea what your doing.
A response from you like I got is no way of getting any help from me or anyone else.
I spent a lot of time trying to help you understand your brakes on another post and not so much as a thank you.
melsg5 also spent some time trying to help you, yet still no appreciation.
With the attitude I am feeling and lack of respect I suggest you just pay to have your car repaired.
