Engine Mechanical problem

I was told that my oxygen sensor at station or stage one, sensor 2 was bad. Where is that located and is it something I can change myself?

It is located on the side of the engien with the #1 cylinder.

It is on the exhaust piping AFTER the convertor.

Buy the special tool used to remove it from a autopart store. And make sure the vehicle is warm before attempting to remove it.

When installing the new one, use antiseize compound on the threads.
