Abstract
La présente invention a pour objet un procédé de commande d’un moteur thermique permettant le diagnostic d’un capteur de pression différentielle d’un organe de dépollution d’une ligne d’échappement des gaz de combustion, notamment pour la détection d’un bouchon de gel. Le procédé comporte une étape de mesure (21) d’au moins une première valeur de contre-pression de l’organe de dépollution à un premier instant. Selon l’invention, le procédé consiste à opérer la mesure de contre-pression (21) en condition de débit nul de gaz d’échappement traversant l’organe de dépollution et à activer (24) un signal de diagnostic représentatif d’un état d’anomalie du capteur lorsque la première valeur est hors d’une plage de valeurs prédéterminée autour de la valeur de pression nulle.
