my code is p0430

Question

A little over a year, I has a new catalytic converter completed on my 2013 Toyota Avalon; Now i have this code. I paid $1655 for the services. The p0430 also stated the o2 sensor could fix the problem as well; so i want to know if im stuck with replacing a new cc all over again?

Hi there

There are several possible causes for this code. If the converter was not a factory replacement it's possible the converter has failed again. But there could be other issues including the rear O2 sensor. Here is a list of the possible causes for the code to appear.
