Bonjour a tous,

Je besoin aide avec interpretation de erreur P2126 on PPS2000 (valeurs erronee de commande de doseur air memorise dans le compteur du moteur - ECU).

Je vous remerciez pour votre aidee.

(Sorry for the errors in the above text - I'm not a french speaker...)

Heu je doute que je vais laisser ce topic ici bien longtemps...

The text for P2126 is different when I look here :

ouais avec la PSP on peut et avec la PS2 aussi mais pas avec PPS.
Sherkan i don't understand!!!!

To Mr. Sherkan:

P2126 has a double meaning; it can refer to the pedal sensor as well, but in this case it reffers to "throttle range". The exact code of the error is "P2126-Permanent fault, Turbocharged air cooler bypass butterfly programming value". I replaced the double butterfly (doseur air) without any change. The values/position of the butterfly valves are memorised in the ECU each time you stop the engine. It seems that these are compared with the data already stored in the ECU memory and are different. If you erase the error with PPS, after 3 re-starts of the engine, the error reappears.
Thank you for your comment, anyway.

To the Others:

Je vous remerciez pour votre temp et pour votre professionelle opinion

glcgsm...

You should either hop over to ilexa.co.uk - the forums on there are for dedicated professionals or take it to someone who knows what they're doing...

To be honest I think you are wasting your time changing parts without knowing what values should be applied to the various parts.

For example the butterfly valves are controlled with pressure/vacuum. although on the DV6TED4 I think they have an electric motor to control them. You should check for any split pipes that lead back to the controller for theses valves... either that or the reading coming from the ECU to the butterfly valves...

P2126 can have different meaning based upon which engine/injection system etc... the best thing is to get a subscription on SERVICE BOX put you VIN number in and then you'll get a correct (99% - one never knows wth these French cars!) answer.

GOOD LUCK!

To Mr. Tonyfinn

Thank you very much for your opinion. From a general point of view, you are totally right. But please bear in mind that I'm very much into details on this particular type of car / engine and I'm 99%... there !!! I miss that 1% yet.... If you are interested in this matter (for yourself, I mean), please let me know and I describe everything in detail for you, in a private message, in order not to disturb the members of this group.

Thank you again,

[tonyfinn]

That 1% though... it makes such a big difference!

Perhaps on the 1.6HDi - that there is reinitialisation procedure for the new part?

I know that it is necessary to do so when replacing the EGR valve (the new generation)

To be honest I'm a little stumped as to why that is necessary but I've read it on Peugeot's workshop manuals.

I don't think the guys will mind this thread being in English for once...

First of all, thank you again for paying attention. I'm glad that it is considered from some of you a subject of general interest. Having these in mind, please note the following:
- DOUBLE mixer valve is a ELECTRICAL double motor valve present only in DV6TED4 which are FAP equipped;
- There are several roles of this device - the most important one is bypassing the intercooler during FAP regeneration phase; it also helps in smoothing stop of the engine by cutting off the admission air;
- There are 3 elements that requests a ECU reset / reinitialization after replacing one of them: 1) EGR (as our colleague noticed), 2) Double mixer valve (my case) and 3) The ECU itself.
- The ideea is: HOW can be erased de previous values memorised / learned by ECU ?? I know several procedures for that, most of them DOES NOT involve the presence of the diagnosis tool, but these reffer to other engine types, not DV6TED4. For this one I found out about a reset procedure that needs another diagnosis tool, not the one that I have (PPS) - which is that used for the Peugeot representative.
This is my 1% missing info.... how to reset the ECU using PPS ?

If there are french speakers interested in the subject and are willing to help, feel free to reply in French. If you want me to, I'll try to translate all the above messages in French, but for sure a lot of information will be lost, and when we speak technical stuff, this might be very important.

Thank you all for your time,

Approximate Eglish-French translation:

Avant tout, merci mille fois de faire l'attention. Je suis heureux qu'il soit considéré de certains d'entre vous un sujet d'intérêt général. En ayant ceux-ci dans l'idée, notez s'il vous plaît la chose suivante :
- La valve de mixeur DOUBLE est un présent de valve automobile double ÉLECTRIQUE seulement dans DV6TED4 qui sont FAP équipé;
- Il y a plusieurs rôles de cet artifice - le le plus important évite l'interseau à glace pendant la phase de régénération FAP; il aide aussi dans le polissage de l'arrêt du moteur en coupant l'air d'admission;
- Il y a 3 éléments qui demande une reconstruction d'ECU / la réinitialisation après le fait de remplacer un d'entre eux : 1) EGR (comme notre collègue a remarqué), la valve de mixeur 2) Double (mon cas) et 3) l'ECU lui-même.
- L'ideea est : COMMENT peut être effacé les valeurs précédentes de mémorisées / appris par l'ECU ? ? Je sais plusieurs procédures pour cela, la plupart d'entre eux n'impliquent pas la présence de l'instrument de diagnose, mais ces reffer à d'autres types de locomotive, pas DV6TED4. Pour celui-ci j'ai appris d'une procédure de reconstruction qui a besoin d'un autre instrument de diagnose, pas celui que j'ai (PPS) - qui est ce qui utilisait du représentant Peugeot.
Manque-t-il mon 1 % des informations ... comment à la reconstruction l'ECU en utilisant PPS ?

S'il y a des speakers français intéressés dans le sujet et est disposé à aider, se sentir libre de répondre dans le français. Si vous me voulez à, j'essaierai de traduire tous les susdits messages dans le français, mais à coup sûr beaucoup de renseignements seront perdus et quand nous parlons le truc technique, cela pourrait être très important.

Le merci tous pour votre temps,

[glcgsm]

Finally problem was solved. The re-initialization of the double butterfly doser is made through Injection Replacement menu in PPS, which is quite odd. Maybe that is way there are few trained people at PGT services - because it is too hard for them too to use the program...(!)

PS.
1) Now I undestand why some of our colleagues are using PS2 instead of PPS to "play" with their cars: It's easier and it really might work !!!!

2) The Moderator is kindly requested to close this topic.

Thank you all,
