Abstract

A method of operating an internal combustion engine 110, wherein the method comprises a calibration procedure of an air mass flow sensor 340 located in an air intake duct 205, wherein the calibration procedure comprises the steps of: - estimating a reference value of a parameter indicative of an air mass flow in the air intake duct 205, - measuring, by means of the air mass flow sensor 340, a value of the parameter indicative of an air mass flow in the air intake duct, - repeating the steps of estimating a reference value and of measuring for a predetermined number of times, - using each couple of estimated reference values and measured values for determining a correction function to adjust the measured values. The method may be performed during an engine cut off condition, in a stable condition or where no exhaust gas is recirculated in the engine. The estimation may take account of intake manifold pressure, total displacement of the engine, engine speed, intake manifold pressure and engine volumetric efficiency.
