  "textContent": "A method for monitoring a fluid injection system is presented, in a system comprising: - a fluid dosing pump, activated by a coil, and - an electronic module, adapted to feed the coil with a driving voltage. The method comprises monitoring the evolution of current (l p ) flowing through the coil and the evolution of the time derivative (dl/dt) of said current (l p ), wherein monitoring the evolution of the current time derivative comprises monitoring two successive zero crossings of the time derivative (dlt) of the current flowing through the coil.",
