I ran a scan on my 2004 lexus RX330 and it brought out a P0430 code. How do I fix it?
Bummer, any way's here goes. causes: Converter failure, Intake air leaks, Fuel injector fault or leak, Spark plug misfire but this usually will set its own code, Timing jumped, ECM failure. Ok there's the things it could be. I would try replacing the O2 sensors first then clearing the code and see if it returns, if it does then there is a probability that the converter is on it way out. Do you have any other codes? If you do fix them first cause the other codes can change air/fuel mixtures thus changing catalyst performance. HTH
