A method is provided for diagnosing a clogging of an injector in an internal combustion engine equipped with a fuel rail and with a plurality of fuel injectors hydraulically connected to the fuel rail. The method includes, but is not limited to determining a value of a pressure drop in the fuel rail due to a quantity of fuel injected by a tested injector, and diagnosing the clogging of the tested injector if the determined pressure drop value is lower than a threshold value of this pressure drop. |
