P0430 HYUNDAI -

Question

Car runs flawlessly. Only code that comes up is 430. When I clear it will sometimes stay off for up to 2 wks. What should I do to fix this?

Answer 1

Even though the engine is running well, the catalytic converter may not be working as designed, to reduce the emissions. You probably need a new catalytic converter.
