I have replaced all of my O2s with new Bosch sensors. I am having one sensor that was fine, but now when it will go unresponsive after driving for a few minutes. The Downstream passenger side sensor is responsive when I turn the truck on and while its idling in the drive way. It will work for a bit (maybe 5 minutes) once I start driving. Then it goes flatline and doesn't come back on. Eventually I will throw a code for it not responding.
I have ordered another, but seeing as they are $50 a pop, I wanted to see if there is something else I should be looking at for why its works some times and not others?
