erreur d'injection df079 df004

[yohnell]

Bonjour. J'ai un gros problème avec mon Espace 4 2.0t. lors des accélérations, principalement des dépassements dans les rapports 5 et 6, une erreur d'injection apparaît et le mode secours est activé. dans les rapports 1 à 3, j'arrive à atteindre 5 000 tr/min et rien. les erreurs df079 et df004 apparaissent sur l'ordinateur. J'ai remplacé le papillon par un d'occasion et 2 capteurs sur les collecteurs. quelqu'un pour aider ? Je suis désolé, mais j'écris avec un traducteur. Je ne connais pas le français.

Hi. I have a big problem with my Espace 4 2.0t. During acceleration, mainly overtaking in gears 5 and 6, an injection error pops up and emergency mode starts. In gears 1 to 3 I can reach 5000 rotations. The computer shows errors df079 and df004. I replaced the throttle valve with a used one and 2 sensors on the manifolds. Can someone help?

Hi

Is it a petrol or diesel engine ?
your signature says 2.0DCI, but you have written 2.0T in your post which is a petrol engine.

I would guess petrol, does the diesel rev all the way to 5k rpm? We also have a throttle and lambda sensors here.

Hi its petrol. I have 2 cars. But I would like to sell this one with a petrol engine. I wrote its 2.0 T. One guy in Poland wrote he change a gaś pedal and it fixed a problem. But all other cars have a diesel engine.

OK, so an issue I had on mine was with the connector of the throttle body, the wires were breaking, maybe you can check that.

and check the harness, if both sensor and throttle body go into the same loom, maybe there is something to check at this level.

Also something that you could check is the air circuit that goes from the intake manifold to break booster, and the head.

La faute était insignifiante. J'ai regardé tous les composants et le tuyau d'aspiration de la turbine s'est déconnecté. Tout ce que vous aviez à faire était de l'installer et de le sécuriser pour l'avenir.
