Bonjour à tous,
Je viens de regarder les logs de ce matin, et il y a une valeur qui m'intrigue (en bleu), et une autre qui pourrait expliquer la panne (en rouge). Cf 2ème pavé.

Si je traduis correctement, un capteur de pression serait débranché (ou défectueux).
Mais de quel capteur on parle ? Un des capteurs de pression différentielle du FAP ? Un capteur de pression de sortie de turbo ?
Est-ce que ça a un lien avec la différence entre la consigne de flux d'air (Mass air flow setpoint = 285,6) et le flux réel (Mass air flow = 399,3) ?
Désolé si ces questions vous paraissent insensées, et encore merci pour votre aide !
