The oxygen sensor is fixed in exhaust manifold, the sensor's signal voltage inputs ECM, according to the input singal voltage, ECM can identify the oxygen content of exhaust pipe. When the mixture is thin, then the oxygen content is high, the sensor outputs about 0.1V low level; when the mixture is thick, the oxygen content is low, the sensor outputs about 0.9V high level. The oxygen sensor singal voltage changes between 0.1~0.9V, ECM will modify the fuel injection quantity according to the oxygen sensor singal.
