I just received this code last summer before putting it away. Reset it several times and it just comes back. Wanna start with o2 sensors. Is there a way to figure out which specific sensor/s it is without taking it somewhere and paying a diagnostic fee?

In short, yes, it is best to either purchase a repair guide or you can go to helms or alldata and purchase a short term vehicle specific subscription (it's like $10 for 3 days).... you can use a multimeter to check each sensor.

P0430 is a code for “bad cats.” Usually it’ll say bank one or bank two. Bank one is passenger side I believe. New o2’s prob won’t fix it.
