    So go out, try the argon, and see how it compares to any of the HC gases
and the pure O2 that Bruce tried earlier.  If the argon/O2 readings are the
same, it is a HC sensor.  If the argon/HC readings are the same, it is an O2
sensor.  Either way, it seems to me as if whichever gas actually produces
voltage is the one it is sensing.
