Sully, I am not Emery, but a heated O2 sensor is sometimes used in a
circuit in order to insure that the sensor operates in th optimal
temperature range to give the most accurate readings. They can be
identified by the fact that they have at least two wires and most of the
time three. The sensor is an analog device that produces a variable voltage
the hotter that it operates. Lean mixtures create more heat and voltage,
and rich mixtures creat less heat and lower voltage. The modem in the
computer interprets the analog signal produced by the O2 sensor, digitizes
it, and varies the fuel injection pulse width accordingly adjusting the
richness or leanness of the fuel/air ratio. Clear as mud, right?
