    If u know u have a bad o2. I guess u must have used a scanner or equivalent. There are 4 o2s on LHS. The way u can tell the difference is by the # sequence that the failure code is giving u. For example the o2s on the right side are even # on the left odd #. Pre cat is 1 after cat is 2. So if u have bad 2/2 Than u know it's right rear or a bad 1/1 is left front ect ect. First make sure u have the right code. With out a scanner. it can be done with a volt meter or a vantage, but it's a heck of a lot easier pulling the codes.
