ABSTRACT:
A sensor is located in the intake passageway of an engine for sensing a parameter representing a function of the air-fuel ratio of an air-fuel mixture produced for the engine and is heated to a predetermined temperature when the temperature of the sensor is below the predetermined temperature above which it is possible for the sensor to sense the parameter.
