I picked up the AutoEnginuity ODB software on ebay to help me diagnose a P0304 code that I've gotten a couple times in the past month. I can tell that the O2 sensors appear to be working, based on the fact that the voltage is fluctuating in a sine-wave like pattern. Is there any way to tell if my O2 sensors are "getting tired" based on the data gathered from the sensors?
