More Information
Summary:A method for diagnosing sensors is provided to diagnose sensors every time by the dynamic model of air flow rate. A method for diagnosing sensors(12,14) allocated to an air supply unit(3) of an engine is characterized in that the dynamic model of air flow rate in the air supply unit is formed by the air inlet and outlet in the air supply unit. Air flow rate of the model and signals generated by the sensors are considered for the diagnosis. The sensors generate signals according to the air flow rate sucked through the air supply unit from the engine.
