If you have the o2 sensor socket it makes it pretty easy.

It's 22m. The O2 socket it perfect. I'm curious as to how you got a 22 mm wrench down there! That seems like it would be very difficult!

I hope thats a joke. Mine didn't do that. I had a CEL and i was throwing several codes related to O2. I replaced the front sensor and reset the CEL. Drove about 15 miles and it hasn't come back yet.
