<p>A method for determining if an injector (10) is in a blocked state, the injector including a coil of resistance R and of inductance L, passed through by a power supply current of maximum intensity (Imax), and powered by a voltage E, the method includes: controlling the opening of the injector, measuring the intensity I passing through a measurement resistance r as a function of time t, determining a necessary durationτto reach a predetermined intensity value (Ipred), lower than the maximum intensity (Imax), computing the inductance L as a function of the necessary duration, if L≧Lth, then the injector is blocked in the closed position, otherwise if L<Lth, the injector is blocked in the open position, with Lth being a threshold value of the inductance.</p> |
