Abstract

L'invention concerne un procédé permettant d'identifier un capteur défectueux, par exemple une sonde de température de liquide de refroidissement pour moteur à combustion interne, qui détermine une grandeur mesurée et émet un signal de sortie dépendant de la grandeur mesurée, qui contrôle quant à lui la plausibilité dans un dispositif d'évaluation, par ex. l'appareil de commande. Un défaut est identifié si, pendant une période prédéterminable, après apparition d'une des grandeurs perturbatrices influant sur la grandeur mesurée, aucune modification du signal de sortie du capteur n'intervient.
