no, the code does not mean that at all.
it is a efficiency code for the cat. you most likely need a cat for bank 2 which is the front bank.

get a real shop to confirm it for you.

I have 2003 is300. the light "check" is on and "trk off" is blincking. Testing showed P0430 code. As I live in Turkmenistan it's problem to find the new suitible cat for my car. Are there any other ways to fix it?
