Hello,

I have included the information that you requested in the diagrams down below. Direct Trouble Code[DTC] P0421 is a DTC that sets when your Catalytic Converter has used up it's expected life span and needs to be replaced. I have included the directions on how to replace a catalytic converter below in the link.
