Abstract

L'invention concerne un procédé de recalage d'au moins deux capteurs (Capatm, Capsural, Capadmi) de pression positionnés dans une ligne d'admission d'air d'un moteur à combustion interne, la compensation de recalage étant calculée pour au moins un deuxième capteur (Capsural, Capadmi) par rapport à un premier capteur (Capatm) de pression servant de capteur de référence entre leurs mesures de pression respectives à une température dite initiale des capteurs lors d'un arrêt du moteur. Il est effectué, préalablement à l'application de la compensation de recalage sur ledit au moins un deuxième capteur (Capsural, Capadmi), une étape de diagnostic interne basé sur la valeur de la compensation de recalage consistant à déterminer si la compensation de recalage dépasse une valeur de compensation maximale, auquel cas il est diagnostiqué qu'un desdits au moins deux capteurs est défaillant. Dans ce cas, l'application de la compensation de recalage est suspendue.The invention relates to a method for resetting at least two pressure sensors (Capatm, Capsural, Capadmi) positioned in an air intake line of an internal combustion engine, the resetting compensation being calculated for at least a second sensor (Capsural, Capadmi) relative to a first pressure sensor (Capatm) serving as a reference sensor between their respective pressure measurements at a so-called initial temperature of the sensors when the engine is stopped. Prior to the application of the resetting compensation to said at least one second sensor (Capsural, Capadmi), an internal diagnostic step is performed based on the value of the resetting compensation consisting in determining whether the resetting compensation exceeds a maximum compensation value, in which case it is diagnosed that one of said at least two sensors is faulty. In this case, the application of the reset compensation is suspended.
