Has anyone noticed a change in O2 voltage logs when replacing the sensor?
Seems you could look at the graph and recognize an aged sensor compared to a new one. I don't think most sensors just quit working when they go bad. They start reporting erroneous readings. Maybe a new one responds quicker and has less deviation? Was just thinking if you could recognize it, you wouldn't have to wait until limp mode to change them.

Yes, sometime the old sensors respond slower. Sometimes the heater portion of it fails, sometimes...
they have have to much resistance inside. If you were to graph over time of the o2 sensors you could see how they respond and compare after replacing, but if they are bad they throw the light on pretty quickly.
