I would be interested in the code numbers. There are no codes that I know of that say the O2 sensors are bad except for the O2 heater circuits. There are some codes on some cars that say O2 voltage too low or high but that is not saying the senor is bad, only that the readings are out of range.

I think they are reading to high.What you said sounds about right. If that is the case how would that problem be fixed (Reading out of range high or low)
