Patience always helps

That and heat, wd40, cold, repeat

And the right tools

For example, do you have the correct six sided socket?

You only really need the offset socket @ramrod mentioned and, if it's stuck, whatever length breaker bar you require to make it not stuck.

Given you're binning the old sensor, you could also cut the wiring harness off it, put a deep socket over it, and hit it with a rattle gun.

As ramrod mention, get it really hot and quench it, with cold water or wd, when your reinstall it, if you have any copper grease on the threads, you don't have to reef on it to tighten it eaither, a couple of heat cycles will help lock it in.
