Hi All, So my 2013 Raptor (6.2L) CEL came on and after checking and attempting to clear the code I wind up with this P0420 (Catalyst System Efficiency Below Threshold Bank 1) and it lists as Permanent and will not clear. I even tried disconnecting the battery. Anyone know how I can clear it (or can I)? I am thinking that this is an indicator of a lazy cat and may need to replace it? and bank 1 would be the passenger side?
