Abstract
Procédé de surveillance d'un capteur de pression d'un système de dosage (20) de carburant dans le canal de gaz d'échappement (13) d'un moteur thermique (10), procédé selon lequel une pompe à piston linéaire électromagnétique établit la pression dans le système de dosage (20) et on saisit la courbe de courant électrique dans la pompe à l'aide d'une unité de commande (17) et à partir de l'instant de départ BMP de l'induit de la pompe on détermine une valeur de pression de comparaison. Pour surveiller la pression fournie par le capteur de pression on compare la pression de comparaison à la pression fournie par le capteur de pression, et en cas d'écart, au-dessus d'un seuil prédéfini on conclut à un défaut du capteur de pression.
