Air Fuel Sensors 06 Tacoma MT

I’m attempting to remove the AF Sensors but I’ve having problems taking the passengers side off. Is there a special way and tools to make it easier to remove them. Do I go at it from the top or bottom? Do I need a special type of wrench. I’m using the oxygen sensor kit from Amazon that has the 3/8 and 1/2 black sockets. Thank you.

 

By 3/8 and 1/2, I take it you mean 3/8" Drive and 1/2" Drive. All of the A/F-O2 sensor I've replaced called for a 22mm socket or wrench. In some cases you can use an open end 22mm wrench to remove/install. A long handled one can help with leverage if there's room. Some have used 7/8". How you approach it depends on it's location, Helps sometimes to first use a penetrant like PB Blaster(example) to ease removal. Disconnect the electrical connector end before you start turning.
