Claims (4)

  1. Procédé pour déceler des sondes lambda dont le branchement a été inversé dans un moteur à combustion interne à deux rangées de cylindres auxquelles sont associés séparément un catalyseur de gaz d'échappement avec une sonde lambda et une unité de régulation lambda reliée à la sonde, et dont les injecteurs peuvent être coupés au moins par rangée de cylindres,
    les injecteurs (7) de l'une des deux rangées de cylindres (2, 4) sont coupés pendant au moins un temps correspondant au temps de réaction ou de commutation des sondes lambda (1, 5) et le signal (U1) de la sonde lambda (1) associé à la rangée de cylindres (2), coupée, est comparé à la fin de la durée de coupure des injecteurs (7) à un seuil (S) prédéterminé et on reconnaît une inversion du branchement des sondes lambda (1, 5) si le signal (U1) de la sonde lambda dépasse le seuil (S) vers le haut ou vers le bas.
  2. Procédé selon la revendication 1,
    caractérisé en ce que
    lorsque le branchement inversé des sondes lambda (1, 5) a été reconnu, les régulations lambda sont bloquées et une installation d'affichage de défaut est activée.
  3. Procédé selon la revendication 1 ou 2,
    caractérisé en ce que
    pour déceler un branchement inversé des sondes lambda (1, 5), on utilise une installation de contrôle externe qui se branche sur une prise de diagnostic du moteur à combustion interne.
  4. Application du procédé selon l'invention correspondant aux revendications 1 et 2 des installations de commande de moteurs à combustion interne pour le diagnostic embarqué.
