P1168 and P0051 Ground Wire?

[sabresfan]

Before I replace the o2 sensor, I found a broken ground wire under the drivers side that appears to run from the body of the vehicle to the exhaust. I temporarily reattached it but not sure it has a good ground. Before I spend a lot of time figuring out how I will permanently fasten it, can anyone tell me if that specific ground is even necessary?

On my 02, I had a code for the driver side rear O2 sensor. I realized that same ground was dangling after a header install- attached it to a good ground, reset light and it's been good ever since. I would connect it to a good ground and reset- it'd be way cheaper than buying new O2 sensors.
