I am trying to find a socket to take out my air/fuel sensor but so far after having bought and tried several sockets, the sockets I tried all seem to be a bit too thick so just can't get all the way down through the hole.
Is there a socket somebody could recommend trying that might fit the one in the picture? 
I would suggest giving one of the below a try. The first two I found on Amazon. The Grey Pneumatic I found on Google using "thin wall socket 22mm" as my search criteria.
Sunex 2622 1/2-Inch Drive 22-Mm Extra Thin Wall Deep Impact Socket
Performance Tool W32926 1/2-Inch Impact Drive 22mm Thin Wall Socket, 1/2" Impact Drive 22mm
Grey Pneumatic 1/2" Drive x 22mm Extra-Thin Wall Deep
