I just received some bad news . I took my car for inspection and these codes popped up p0440, p0430, p0446. Now I've been reading up on this and I've been told to change my catalyst converter. When I start my car sometime u can hear a rattling sound I think there's a hole in my pipe but I need help on what to fix so I can pass inspection ... can someone help please 🙌✌💯💯

By the brake master cylinder, to the left and down, there is a vacuum line with a green cap, make sure all the lines are attached as mine came undone and triggered the same codes as you listed. It could be a long shot, but its a hell of a lot cheaper than a catalytic converter.

Check your exhaust system for leaks prior catalytic converter replacement. (p0430)
p0440 and p0446 refer to the evap system.

thank u sir , I'm gonna check for leaks first but if I need cats I'll let u know . By the way my battery had died I brought a new one , I haven't checked codes yet but could a bad battery during inspection caused this ???
