Oxygen sensors are in the exhaust pipes; therefore, how is it that they monitor the volumetric ratio of air-to-gasoline which is in the intake side of the engine? If by inference, this implies that the sensor controller has an algorithm which assumes a combustion efficiency of X%, no? I guess that the sensors are actually looking for a combustion byproduct, and by stoichiometry, deduce the theoretical air-fuel ratio? If so, what parameter and equation is employed?
