Hi, I'm a newby and only know a small amount about cars in general.
We took it to Auto Zone and they were able to clear all the codes, but this one remained. Bank2 Slot2. Does anyone know what that means?
I read on a handyman site that one should go to the manufacturer of the reader's website to find out, but we didn't get that info. Is that correct?
Thanks for any help.

 

When it says bank 2 slot 2, it usually means that the engine is a V6 or V8 engine
One side of the V is bank 1 and the other is bank 2.
Slot 2 .. it means that there are two O2 sensors. Slot 1 .. one is after the exhaust ports and Slot 2 .. the other is after the catalytic converter.

Should get a Haynes manual to actually give you picture or diagrams of where it can be found for your vehicle.
