I have a standalone and my CEL light hasnt come on yet.1st 02 sensor means the 02 sensor that is on the 02 housing. Secondary 02 is the one on the cat/exhaust.

The "second" O2 sensor is for emissions, tells the ECU if your cat is working fine. If you have a standalone, I think this sensor is not even being used. The "first" sensor is the one in the O2 housing.

can you confirm this? Should I save my money and not get the second 02 sensor welded? As long as im not getting a CEL it should be ok right?
