Error P2455 Alfa 159 1.9 jtdm 150 hp edc16c39 cf4

[dvdtuning]

Hi all, this error in diagnosis as "plausibilit? sensor differential pressure dpf" I wanted to know if ? symptom of dpf from trouble, or ? only the sensor to be replaced?
Car engine failure but normal performance.

[motorsport_1970]

Surely the sensor that lacks the you can replace
the price it seems to me, is about 50-55 euro
the degree of clogging of the dpf as you can see in the diagnosis
otherwise you permanently delete and you're quiet

[msport (exil77grande)]

the filter may be plugged, or the sensor is defective, or, even worse, the pump, the low pressure is lacking because dirty or is just starting...or the pressure regulator of the low, who is on the rail that connects the filter and the input pump rail...

I think, however,' the problem we have on the particulate filter,if you need the forum carries out these services that will soon be included in the on-line shop.

[dvdtuning]

If you decide? to remove it you will see?... in the meantime, I replace only the sensor, and let's see!

well if you have to try to solve the problem without a specific request to delete the fap in fact, you should start from the sensor, then if you don't solve possibly eliminate completamente.l

[dvdtuning]

It in fact. I recommended to remove it before the start of the problems for? the decision is not up to me.

[cattivik]

the same problem encountered on a 159 JTDm 150 hp and as said motorsport solved by changing the sensor

[cattivik]

changing the sensor...

[dvdtuning]

Not ? back yet...she said that ripassava but still nothing!

[cattivik]

ah sorry... I thought it was reported to me :-)

[davidehfnos]

I'd recommend you to delete the dpf and egr and via

[giarras]

sar? surely the sensor, see to convince the customer to sfappare are often frequent these anomalies both on chrome and on the 159, sfappando resolve a few issues

[dvdtuning]

I confirm, changed the sensor and the error disappeared.

[meccano85]

that surely ? the sensor limit, try to clean it first!!

[msport (exil77grande)]

that surely ? the sensor limit, try to clean it first!!


in fact, he wrote that he replaced the sensor and it has solved.

[meccano85]

Yes, I had escaped....anyway, the fiat group with bosch ecus are the most easy-to-deffappare and, above all, do not give problems later....and then had to force a hardware problem

[meccano85]

definitely makes it more than other cars....

[dvdtuning]

Today I ricapitato the same problem on another 159 on which had been done previously, a luca stanca with some sw (not by me) and in the diagnosis gave error dpf... Then I deleted the dpf from the switch on the file already mod because I had no gold and error dpf gone, but remains sensor error pressure differential...at this point I think it is the sensor to be lacking?

[dvdtuning]

Resolved after you found the file ori and the past with the time!

[Xtreme0303]

Colleagues have had problems on the mjet and time with regard to the fap..

Hi, I attack in this discussion to describe my situation.
Drive 150 150hp jtdm q-tronic, purchased in km.0 and since the first km. showed occasional vibration between 70 and 80 km/h.....the dealer burned me 2 years of warranty, making me believe it was the fault of the EGR....but from 2 weeks I deleted the EGR and DPF gaining a greater recovery and losing in consumption :-) but that damn vibration ir? accentuated cold ? remained. The injectors for both hot and cold are within the range of correction +-30 about all 4, I tried to clean the turbo pressure sensor in place next to the egr but I have not solved anything.....then today I tried to clean the sensor rail pressure placed on the flute....and I have to admit that the situation ? improved a lot. After it's out of me ? out of the diesel from the flute ? normal? After you returned the car ? the game immediately...but after 2 tests and pressing the accelerator ? normal? Now runs better.....can I then assume that the problem is in the sensor, rail pressure?

Thanks 1000

Sorry for the car ? a 159...me ? ran the 0 :-)

[max boost]

certainly that ? normal is that usce diesel is that we put a p? starting...you must fill in the circuit ? autospurgante. Anyway, I appreciate the courage to disassemble it and look for the catch without knowing precisely how it works this injection

[max boost]

For the defect you say ? a vibration occasionally, but to understand ? a traballamento or hesitation why? to me the word vibration, I think the effect of a flywheel shaky or joints, those on the gearbox side(defect fairly well-known workshops alfa romeo) given that only manifests itself at a certain speed?...

[azzis77]

Thanks..also for the courage :-) hihi. Anyway. Premising that after the cleaning the problem is reduced to...say that it is a ****llo joints on the gearbox side or the axle shaft of the saw:
1'. I mount the q-tronic
2'. When you predenta the vibration...semettevo in N neutral the vibration disappeared.
Thanks 1000 for your help....I turned to mechanics who sincerely try to take you for a ride... :-(

[azzis77]

And not always in the same way...with a cold engine, more pronounced..the engine is warm, less marked, or sometimes even feels. Perhaps the potentiometer of the throttle? Boh.....cmq. tonight I used it and the vibration was practically minimum.. .

[123alexs]

also check the exchange, an acquaintance of mine after many interventions resolved with an intervention on that but I have been able to say more?

[azzis77]

I also did a further test as consigliatomi from pompista...... while on the 75km/h and feel the vibration if I put the gear in the "N" neutral the vibration disappears. It is due to the engine then? The exchange has no problems....goes perfectly!

Thanks 1000

[johnny]

I don't know if he can be of help, but one of my customers happened something like that he also identified as a vibration but really? were the valves swirl blocked, and unlocked.

[sa80libero]

but in diagniosi the percentage of clogging as is? already from them, you can understand if and clogged the filter or not

[azzis77]

DPF off and EGR off....... the swirl will only lock from 70 to 80km/h?.... me has been the new car...
