Problem IVECO STRALIS

[usardaun]

hello robby51039, I have sent you a private message!

anyway, replaced the filter, and not the support!

injectors replaced a year and a half ago, it has done 150,000 km!

hi all, a information, the vehicle in question, rips or vibrate if put under strain when these loss of power?
if ? so very probably ? a problem of poor supply of diesel, unfortunately it's not? tell you what must remain the press feed, but if you can go back to the data you council to carry out the measurement with the gauge in the road and the vehicle is under load, why? I ? already happened that stopped the pressures are right, but under stress, the pump could not maintain a sufficient flow rate
if the medium is not ripping test to check the sensor turbocharger, you can verify the correct operation only with a pressure gauge and a diagnostic tool at the same time and compare the values are always under stress (no.b. sometimes the sensors marked correctly, but in certain conditions of pressure and temperature sfalsano the measurement giving the wrong information to the controller, which accordingly adjusts the fuel injection and will not turn on no light why? the control unit is not allowed? verify the correct operation of the sensor, except in the case of a short or open circuit
hope that was helpful and let me know

oh, I forgot, in the case of a low supply pressure, first check all the system following the prercorso of diesel fuel, starting from the float as a gi? recommended by other colleagues, and replace all of the filters including the air motor (which from personal experience can? give these issues the cio? poor yield periods) and if still the problem remains try to replace the pressure relief valve of the diesel and for the last, the pump

hello igor, after replacing the two diesel filters we say that still I am defect cali occasional power!! then I took a look at the air filter, and I noticed that there were two clips that hold the cap on the filter! I opened the cap and I found a little water and the filter is soaked!! I placed the cap of the filter, changed the air filter, and it seems that half goes! pu? be that from the cap entered the water when it rained and dust, giving the sti loss of power at times?

[igor]

? likely
let's say that if the filter ? dirty pi? wet air can not pass and, therefore, the vehicle is not breathing
if the problem reoccurs check the sensor turbocharger and clean it with a rag moistened with thinner
speaking with Sisco at work today we remember that the overpressure valve diesel in the vehicle ? integrated in the pump and can not? be replaced (provide only the pump)
but if you tell me that only by replacing the air filter seems to work better then ruled out a power problem diesel fuel, if the vehicle smoked black ir? usual during these cali?
if you was almost certainly the filter, otherwise it could be the sensor, I repeat may
I hope this information was helpful and you have found the problem

[usardaun]

Yes, I confirm, when it was not smoked more? of the usually!

[igor]

ok then, problem solved

[sisco]

hello usardaun it seems that the solution to the problem of the iveco is taking a positive way,I remembered that once a scania was and was not when he felt like it we discovered that it was pulled off the pin that drives the throttle valve of the engine brake that is activated at random, maybe ? the first thing you looked at, but you never know, hello keep us informed

[usardaun]

ok, terr? informed, we hope we have solved it!

[robby51039]

I'm glad that you've solved sometimes we puzzle over problems absurd and lasoluzione it is a good maintenance I only hope that my tips have been of help
