The pressure sensor is located downstream of a flow regulator and upstream of the ATI in a conduit for supplying of a substance from a container to the ATI. An ECU is programmed to perform a predetermined sequence of opening and closing commands for the flow regulator and the ATI, furthermore perform a frequency analysis of the measured pressure value in order to monitor the functionality of the flow regulator, the ATI and the pressure sensor. The method is adapted to be used in connection with an On Board Diagnosis (OBD) system.
