Most likely that o2 sensor is actually a wide band A/F sensor. Wide bands work between 2.0 and 4.0 volts. 3,2ish represents stoicheometric ratio. Below that is rich and above that is lean. Scanner is just listing it as an o2 sensor. Not 100% sure on that particular vehicle but that would be my guess.

P.S. The additional lines of data pertaining to o2 is likely heater information
