My code that pops up is P0430 bank 2.
Please tell me what it is and how to fix it .

More than likely it's a bad catalytic converter on the passenger side. To fix it....Replace it with a new one.

^^I agree, most likely going to be a passenger side cat. P0420 is your drivers side, P0430 is your passenger side. Depending on your emissions, you have the option of taking them off completely or you can just get a single replacement. One thing to think about though is if your first one is gone, your second one is definitely prone to go out sometime as well

... the code is intended to point to a bad cat, but it could be other things.

IMO - Starting with the most expensive repair without checking the other inexpensive (but less likely causes) isn't the best way to go.

This code indicates a reduced oxygen storage capacity of the cat. If you don't have a sniffer test then this is no big deal. If you have a sniffer test to pass, you will likely need to replace the cat.

I had it ran again its my converter.Should i just take them out completely ? Making straight pipes? Or just repair it

It's really up to you. Do you have emissions with a sniffer test that you have to pass in your state? Do you want your car to be louder than what it is now?

You don't have to do either. You can just tune out the code and forget about it if you want (this is what I did), assuming you have no sniffer. Or, you could delete the cats entirely (if you have no sniffer), or you could replace them if you need to.

The choice is yours.

Im in CA idk what a sniffer is.Most likely not

KevinR

Since you live in CA, I would replace it if I were you. Again, it's completely up to you.

A sniffer is an emissions test. Since youre in ca, you definitely have a test to pass. It could be your cat but it could also be your O2 sensors. You can swap the lowers and reset the light - if it comes back its even more likely that its your cat. Theyre expensive which is why a lot of people tune them out.

If you replace it, go with an OEM unit - aftermarket ones are not usually as efficient and the light will likely remain.
