I got a p0430 code and I wanna make sure it is not my cat thats gone wrong. I want to check the o2 sensors but I dont know what the voltage should be while on the car and warmed up. Can you help me by telling me how I can test them and what the voltage should be? Also what else I can test to make sure its not my cat?
