So I have done about everything to get this code to go away. It is a Cali emissions car so it has 2 cats. I replaced both. The exhaust manifold/cat one I got straight from Toyota. The one mid exhaust I got from the local parts store as a complete pipe/cat assembly, the brand was Walker. I've also replaced plugs, wires, fuel filter, air filter, just to eliminate those small things and get it running good. So what do you guys think? Any suggestions? O2 sensors? Thanks

I hate to say this but the one that is a walker brand is the main one that causes cat codes on calif. emission toyotas. The front one is like a pre cat. I dont know if the front one was available aftermarket but the one that should be oe is the rear one. I know they are expensive but me or you either one cannot help that right

this my own definition of oxygen sensor.,.
oxygen sensor, or lambda sensor, is an electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analyzed..
just keep going and keep up the good work.,
