p0430 code
thanks
There is a possibility that your o2 sensor just crapped out. They can go at any time really. Seeing that only one code is showing up (please confirm you only have one code) you could try and take your rear o2 sensors and swap them from passenger to driver and see if the code flips over to the other bank. Right now your code is for Bank 2 post catalyst. So the o2 that could be in question is the rear passenger side sensor. What you would want to see is the code move. meaning it goes away on one side but shows up in the other side of the system.
First and foremost make sure you only have one code showing up that relates to your o2 sensors.
If you have 2 codes (on for the driver and passenger side) the chance of those o2 sensors being bad still exists. However it would most likely indicate that you should speak with your tuner and let them know of the awesome mods you installed and you would like to make an equally as awesome adjustment to the tune.
Hope this helps. -Mike
