Yup. That's the code.

I'll see if the local muffler shop can name the converter.

Any way for me to turn off the engine warning light?

Thanks.

Unless you want to disconnect the bulb at this point. If the problem is there, it's going to continue to show itself until solved.

I just got that code on my ES after I had the misfiring issues...

I got the 420 cat eff. bank 1---so Im guessing the misfire caused unburned fuel to go into the cat?

Which one would I have to replace?

Technically, the sensor after the main catalytic converter is Bank 1, Sensor 2. It's an O2 sensor that will trip the P0420 code. The sensor is visible from the driver's side.

Do you still get the code right now?

I got the code about 30 miles after I fixed the misfire issue..which was last night

I erased the code and I'm gonna wait to see if it comes back...hopefully it goes away.

But it doesn't specify which sensor in bank 1...
