Abstract
Disclosed is a method for detecting pinching or twisting of a discharge pipe connecting a fuel tank and an absorbent filter of an evaporation system of a motor vehicle. The method includes the steps, with the valve being initially in its closed position, of moving the valve by the gases circulating in the absorbent filter, of measuring, in the absence of control of the solenoid, the voltage generated at the terminals of the solenoid by the movement of the valve, and of detecting pinching or twisting of the discharge pipe when the voltage measured is between a first predetermined threshold and a second predetermined threshold.
