What is the P430 error code on a 2003 Toyota Highlander?
That code means that the oxygen sensor downstream of the catalytic converter on bank 2 is detecting that the converter is not working as efficiently as it should be. It could be a bad oxygen sensor, a bad catalytic converter or and exhaust leak.
What is the lifespan of a catalytic converter?
That depends on the engine and the fuel you've used. If the engine starts burning oil a catalytic converter can fail rapidly. Some fuel additives can also cause a catalytic converter to fail prematurely.
