Oxygen Sensor is one of those components in Chevrolet S10 vehicles that are responsible for regulation of oxygen concentration in exhaust gases in order to adjust the setting of the air and fuel mixture and reduce emission levels. It produces a voltage signal proportional to the oxygen concentration; the signal is used by the engine control computer to increase or decrease the fuel injector pulse width. This feedback mechanism makes the engine function in a 'closed loop' to improve catalytic converter effectiveness. Some Chevrolet S10 models employ zirconium dioxide oxygen sensors, maybe both the upstream and the downstream sensors. The upstream oxygen sensor gives the information that allows the computers to change the air-fuel mixture while the downstream oxygen sensor checks on the catalytic converter. Some of the newer models may include wideband air fuel ratio sensors, this will be different from the more conventional and restricted band sensors. But all types of fuel injectors are subjected to contamination and degradation over time which in turn results to more emissions and poor fuel economy.
