my 2016 Chrysler town &Country touring 3.6l P0420 & P0430 Pending & Permanent, Replaced the 4 O2 Sensers Mopar, Replaced Both Catalytic with Walker Brand.
Is that caused by the 2 Cat. or may require 5 Gas Analyzer Test?

There are many possible causes of those codes. You may have replaced those parts unnecessarily.
