I'm trying to identify which bank the catalyst converter is located in for my 2000 Mazda MPV 2.5L California model, specifically regarding OBD-II fault code P0421. Could someone clarify whether it's Bank 1 or Bank 2? Additionally, what are the recommended fixes for this issue? And how long does a typical catalyst converter replacement take on this model?
