With the rapid development of automobile industry, the traditional carburettor vehicle is bound to be replaced by the electronic fuel injection vehicle for environment protection reasons. The oxygen sensor is an important device in the electronic control system of the electronic fuel injection vehicle, which makes the engine get the mixturegas with best concentration and gets the purposes of reducing the emission of harmful gases and saving fuel. An advanced oxygen sensor used in the electronic control system of the electronic fuel injection vehicle, four-wire and chip of oxygen sensor for automobile, is introduced from three aspects of fabrication flow, working principle and test method, which provides the basis for the diagnosis and application of this kind of sensor.
