Hi guys,
Sorry guys, I am stupid! Now I know how to find all info needed, thanks.

I used Bluedriver OBD2 for checking Highlander 05: I found P0420 and P0430 code (attach files included)
I cannot see bank 1 sensor 1 and bank 2 sensor 1 on display list of Bluedriver. Is it normal?
I replaced: PCV valve (1st time), and fuel vapor feed hose 23820-20210 (cracked) before buying Bluedriver for diagnosis.

Thanks for your help,

Age and mileage would indicate the cats are worn out and need replacement, their efficiency is below the designed threshold hence the 2 codes.

Hi,
I thought that I should see both sensor 1 and sensor 2 from each bank. That why I have my question.

I would think so also, I'm not familiar with that tool to know why not. Yet the codes indicate sensor 2 issues (02 sensors). Could also be exhaust leaks causing those codes.

Not familiar with the scan tool you have, but suggest trying another one to see if you can retrive the fuel trim info!
Those two codes are for cat below efficiency thershold, aside from bad cats, there are other causes that can affect that!
