P0420/430
My car details; 2005 4runner SRS5 4WD V8 4.7L 84,570 miles, presently VSL trac/trac off & maintenance light came up on dash board. I checked the codes and got P0420 & P0430 Codes, I was thinking of changing the four o2 sensors but a mechanic recommends that I should try catalyst bypass.
Also the fuel consumption is extremely bad.
I was able to use Actron CP9580 to check the car, I know this is tending towards replacing the CAT's, can anyone explain better what the data below means;
