O2 sensor live data doesn't correspond with code being thrown!
I have a code for heater circuit malfunction on my upstream bank 2 sensor. I did some live diagnostics before getting the replacement part... And it seems both upstream are working fine The Bank 1 downstream sensor seems to be completely dead I'm not sure if Bank 2 downstream should look like that either. What's going on?? Is one of my catalytic converters completely blocked? This data was taken with the car idling in Park. Thanks!
