Does our stock O2 sensor output on a 0-1v scale or 0-5v scale? I ask because the BGB shows the diagnostic connector output range to be 0-5v but that is coming from the ecu and not directly to the sensor so I would be inclined to think that the sensor is, like most sensors, on a 0-1v scale and the ecu adjusts that for easier diagnostic with a voltmeter.
The reason I ask is my PLX wideband provides for a 0-1v narrowband output and my stock 02 sensor is failling, as indicated by a leaning out of the mixture whenever the car switched to closed loop at cruise. I'd rather use what I have then spend money to replace the sensor when I don't need to.
