Good evening everyone, got a check engine light on my 2022 gt2 code "P0430 Catalyst System Efficiency Below Threshold Bank 2." I understand that there is a total of 4 O'2 sensors with 2 being on each side, I was curious if anyone else has gotten this code and happened to know which sensor I need/which side its on/before or after. thank you for looking.
