HO2S-11 Sensor

Anyone with advice on the removal of the HO2S-11 sensor.Are any special
tools required? I know the location of it and it looks pretty easy to get to
but Im not sure how it should come out. Thanks

Spray it with something like WD40, let it sit overnight. It believe it's a 7/8" wrench that you'll need. One that I changed started to round off the hex using the open end of a combination wrench. You can't get the box end over the connector, so I cut it off since I was replacing it anyway. This one was tight and I had to rock it back/forth. It messed up the threads a bit but I was able to install a new one easily!

I find out later that they sell a O2 socket that's slit for the wire to clear. I bought one and used later on one that came out easy anyway!
