ok so i check voltage on other harness.

First sensor measured 10.45v second measured 10.47.

I measured the voltage sing the obdII and I was getting 0.455v and 0.455-0.456. Seems like the voltage is close to the same. I guess im gonna try switching the sensors areound and see what happens.

If I kept the sensor plugged in and removed it from my exhaust pipe and plugged the pipe with a bolt would this eliminate my cel? I wanted to test to see if this would eliminate the cel and then I could also check to see if the sensor was actually heating up?? Let me know if this would be a good idea? At least then I would know if the sensor heater is working.
