Abstract

Dans un procédé de contrôle du fonctionnement d'une sonde (11) associée à des moyens de purification (7) des gaz d'échappement d'un moteur à combustion interne (2), on compare un signal de sortie de la sonde avec une valeur de référence, et on agit sur la sonde (11) pour diminuer un écart entre le signal de sortie (S1) et la valeur de référence.
