Watching Live Data of 02 sensors.

[Myco]

I have a 97 mark viii. I watched the live data of the 02 sensors to see if the catalytic converters are working correctly.

What I found is one 02 sensor not reading anything. I need to know how to find which catalytic converter it is that is not working. Does anyone know the names of the different 02 sensors when you get the readings off an OBDII scanner.

Thanks in advance.

Bank 1 is pass side. Bank 2 is Drivers side. O2 sensor 1 of either bank is one closest to engine exh port. And of course all Sensor 2 O2's are downstream of first ones. The code reader will tell you all sensors with terms like Bank 1 sensor 1. B1S1 get it? That would be pass side front sensor.
