Fig. 2 HO2S Circuit
The HO2S resistance varies with temperature and so a heater is used to maintain a constant tip temperature of approximately 700 °C. At this temperature
the sensor output will be 3.3 V for lean running and 1.1 V for rich running. It takes approximately 20 seconds from engine start for the sensors to reach
an active temperature of approximately 500 °C.
