I've been getting these codes on my car. They are obviously O2 codes. Does anyone know if they pertain to a single O2 sensor and if so which one so I can figure out which O2 sensor I need to replace. I.e is bank 2 the black or gray sensor and is this the forward or back part of the downpipes. Thanks for your help.

I got the 2C7F fault today with strange smells. Did you resolve your 2C7F fault? If so, how did you do it?
