Abstract

Procédé de détection de l'occurrence d'une ligne ouverte dans un capteur comportant un élément de capteur pour saisir au moins une propriété d'un milieu fluide, notamment des gaz d'échappement d'un moteur combustion interne et au moins un élément chauffant, n'appliquant la puissance de chauffage que pendant au moins une période à l'élément de capteur. Pendant cette période, l'élément de capteur génère au moins un premier signal de mesure (122) et en dehors de cette période il génère au moins un second signal de mesure (124). L'occurrence d'une ligne ouverte dans le capteur se détecte en ce qu'au moins le second signal de mesure (124) correspond au moins au premier signal de mesure (122) à l'intérieur du seuil (132).
