If you have a bad 02 sensor on an OBDII car, you will have a check engine light on. pull the codes and it will tell you what sensor is bad. Why do you believe the 02 sensor is bad?

He did not post in the same thread where he started with that subject, that is why it is confusing. Here is the start iof the story

I had a check engine light before I lost power to my car with a poorly grounded negative battery cable, before I fixed that the check engine light was on. I had it read at Auto Zone and the code reader said bank 1, something, something slow O2 sensor response. Since I have 4 O2 sensors I am trying to figure out which one the code reader was referencing because it wasn't clear. For instance it didn't say passenger rear, or passenger front 02 sensor, I was just hoping someone knew which sensor was which in the code reader language so to speak.
