Tracy, the code you list is for bank #2. In the case of your vehicle, that would be the sensors associated with the back 3 cylinders (cylinders 4-6) or the exhaust pipe nearest the firewall (same pipe, different way of finding it). So, odds are, you may need to replace the upstream O2 sensor (the one nearest the engine) and see if that fixes your problem. Based on the fact that your car just passed emissions and you are not complaining about a rotten egg smell, odds are your catalytic converter is just fine.

If you need more info, just hollar.

 

Tracy, you got lucky when you passed smog. That p0430 code is a catalyst effeciency code, meaning the catalyst material is compromised and the downstream 02 sensor is doing it's job, along with the upstream sensor notifying the ECM of the catalyst ineffeciency. This code is very common on your model with higher miles, say over 60k like yours. If you can hook a datastream tool to the car, the downstream 02 sensor should read .5v approx. and not fluctuate. If it does fluctuate say from .1v to 1v, the catalyst needs replacement. Do this when the engine is at running temp. I'd bet you need that cat replaced based on miles and that code. Good luck.
