obd codes

My check engine light came on and i had a computer check done on it. The code is P0430A and then it said TWC system low efficiency bank 2. Can someone tell me what this means. Thanks.

I'm sure you'll find it handy in the future. Gives you a possible cause for the code too.

Thank you for the info, I was searching for the codes, but couldn't find them. Also, does the A mean anything after the P0430

Thanks for the info. Does the A after th code mean anything special

TWC stand for two way catalitic converter. IE, the cat is bad.

Its a pretty reliable code, when the code sets, your cat is bad. Bank 2 means you have more than one cat. You need to figure out which bank is which on your engine....or you need to mention what vehicle it is and what engine it has

The "A" doesn't mean anything

Thanks for the info I couldn't find out what twc meant. I was told bank 2 was the passenger side, is that correct?
