Hi everyone,

About a year and half ago my converter blew out. I replaced the converter and 02 sensors and am getting a reoccuring P0430 code. I usually clear it and it goes away for a few days until it comes back. Any insight on why this code keeps returning? I do have a leaky muffler, would that cause a low efficiency code?

Thanks.

 

Which converter did you replace? Driver or passenger? I think 0430 (bank 2) is drivers side, so if you replaced passenger but not driver, it could be a failing driver cat.

If you replaced the driver cat, then it could be a number of other items. (https://eeuroparts.com/blog/p0430-fa...eshold-bank-2/)
