A large oxygen concentration difference results in about 1 volt and a small difference results in about 0.01 volt. To put it in other words, if the
amount of oxygen in the exhaust gases is less (air-fuel mixture is richer than the stoichiometric mixture), about 1 volt is generated. If more (air-fuel
mixture is leaner than stoichiometric mixture), almost none is generated (Refer to chart in accompanying image). In this way, the HO2S detects
whether the oxygen concentration is high or low (or the mixture is leaner or richer than the stoichiometric mixture).
