Re: O2 sensor draining battery?

I removed fuses one at a time and when I removed the O2 sensor fuse, current drain went to zero. Left the fuse out for now, seems to run fine but I am wondering what makes it do that? do I just replace the sensor? Is there more than one? where is it located?
Any help would be appreciated! thanks in advance!
On newer Sportys there are two oxygen sensore. One before and one after the cat converter.
