SOURCE: DTC Code P0430
WOW, THAT CODE IS FOR ALL THAT.
EXHAUST FAILURE, CATALITYC FAILURE AND O2 FAILURE.
I WILL SAY TO REPLACE THE O2 SENSOR WICH IS THE CHEAPEST WAY AND SEE IF THAT;S THE PROBLEM. BTU FOR TIME AND AROUND 120,000 MILES THE CATALITYC GOES BAD.
BUT I WILL GO FIRST WITH THE O2 SENSOR.
IF YOU CAN'T FIND A GOOD DEAL LET ME KNOW I CAN GET THEM CHEAP " AROUND $ 60.- "

P0430 means that the O2 sensor behind the catalytic converter is detecting that the catalytic converter is not functioning properly. This can be caused by a bad sensor, and exhaust leak or the actual catalytic converter is bad. Check for leaks 1st. The sensor is changed by unhooking and unscrewing it from the exhaust pipe, the catalytic will need to go to a repair shop. Hope this helps, let me know.

P0430....Catalyst System Efficiency Below Threshold (Bank 2)
yes it could very well be a O2 sensor and the quickest way is to test with a multi meter ,their are 2 sensors on each bank ,now each sensor has four wires and two of the wires are the same colour ,so check these two wires for 12v supply coming to them ,then the other tow should show a varying current as engine ides and is revved a little ,

A code P0430 may mean that one or more of the following has happened:
It is most likely that an O2 sensor just prior to the catalytic converter has gone "lazy" and is not reading properly. To remove the O2 sensor, I would soak the sensor first with a rust penetrant and then you will need a 7/8" wrench or socket (depending on the sensor's location).
