A device (D) is dedicated to controlling the operation of an internal combustion engine (M) including at least two cylinders (Ci), each equipped with at least one inlet valve (SA) and at least one injector (IJ), and of the so-called indirect and sequential fuel injection type. This device (D) includes detection elements (MD) designed to detect an injection event phasing error relative to reference angular positions specific to the various cylinders (Ci), and control elements (MC) designed to rephase, if a phasing error of a cylinder (Ci) is detected, the command to open the injector (IJ) of this cylinder (Ci) after closure of the inlet valve (SA).
