I got a cel that told me I needed to change the bank 2 sensor 2 oxygen sensor so I went out and bought and OEM replacement part, jacked the car up, and went to work. I tried to use an open ended wrench and one of the special O2 sensor sockets but neither of them worked. The sensor seems to be rusted on and won’t budge. I also tried to use all of the different liquid wrench options as well as 50/50 auto trans fluid and acetone. None of these worked and I am stumped. Is there anyway that I can cut the sensor off and get an impact or a breaker bar on it? Or is there any other options I have to try and take it off? Any advice is massively appreciated.
