The P 0420 is a cat code the P0446 is evap vent control fault neither will cause the speedo to stop working.You need to have a professional scan tool scan your car and not a diyer scan.The professional scan tool can scan all the computers for codes.The diyer scan tools can only scan generic obd2 codes.
