Abstract

L'invention porte principalement sur un procédé de contrôle de conformité au montage d'un capteur de pression différentielle (17) comportant un piquage de pression (18) en amont et un piquage de pression (19) en aval d'un filtre à particules (16) de moteur thermique (10), caractérisé en ce que ledit procédé comporte: - une étape de réalisation d'au moins une première mesure par le capteur de pression différentielle (17) lors d'une première phase de fonctionnement du moteur thermique (10), - une étape de réalisation d'au moins une deuxième mesure par le capteur de pression différentielle (17) lors d'une deuxième phase de fonctionnement du moteur thermique, et - une étape de validation ou non du montage du capteur de pression différentielle (17) en fonction des mesures réalisées.The invention relates mainly to a method for checking compliance with the mounting of a differential pressure sensor (17) comprising a pressure tap (18) upstream and a pressure tap (19) downstream of a particulate filter. (16) of a heat engine (10), characterized in that said method comprises: - a step of performing at least a first measurement by the differential pressure sensor (17) during a first phase of operation of the heat engine (10), - a step of performing at least a second measurement by the differential pressure sensor (17) during a second operating phase of the heat engine, and - a step of validating or not the mounting of the pressure sensor. differential pressure (17) according to the measurements taken.
