Abstract

The present invention relates to a monitoring method for monitoring a fuel injector of an internal combustion engine of a vehicle, the injector comprising a piezoelectric actuator which acts on a valve means in order to open or close the injector, the fuel injector comprising an actuator play, the method comprising: • a step (100) of measuring a plurality of compensation times of the actuator play (TMES) during a simulation step preceding an injection for a given plurality of fuel pressures; • a step (200) of calculating a parameter representative of the current actuator play (PAR(Jc)) in accordance with the measured compensation times (TMES); • a step (300) of comparing the parameter representative of the calculated current actuator play (PAR(Jc)) with a predetermined reference parameter of the actuator play (PAR(JREF)); and • a step (400) of transmitting a warning message in the event of the reference parameter (PAR(JREF)) being exceeded; the parameter representative of the current actuator play (PAR(Jc)) being calculated on the basis of a polynomial function of the measured compensation times (TMES1, TMES2, TMES3); the polynomial order of the polynomial function corresponding to the number of measured compensation times of the actuator play (TMES1, TMES2, TMES3) for different fuel pressures (P1, P2, P3).
