SOURCE: Chrysler LHS o2 sensor testing
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.

If you have trouble codes stored in your cars computer for O2 sensors a fuse will not fix it. One or all of the O2's may need to be replaced. There are test that can be done to confirm which one.

You have them tested, by a repair shop, that has the knowledge
and proper test equipment.
You never replace any part,based on a code alone
The code you got, will indicate which sensor,but
not that is bad,got to test
