2003 Lexus IS300 Question: code p0430

which one is bank 2 saying to replace o2 sensor or refering to cat conventor check for exhaust leak none found thank you -
Answer 1
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. Roy -
