Nu Trece de 4.000 rpm

verifica debitmeru aer.... incearca sa scoti mufa si sa accelerezi.. ECU baga o valoare generica atunci...
ar mai putea fi calculatorul pompei de injectie.. un contact slabit.. daca numai la cald se manifesta problema

ideea era ca daca mergea prost cu sau fara debitmetru atunci sigur era stricat.. cel mai bine este sa-l masori ... eventual sa-l dai jos si si sa-l cureti cu aer comprimat.. cauta pe forum tutorial
mai verifica si EGR-ul.. furtunasul de vacuum.. filtru aer...

sunt de-acord cu adware_man pe tester trebuie sa indice niste parametri la senzori care nu te lasa sa dai mai mult de 4000 rpm. la mine a fost senzorul map dar imi aparea si check engine.
noi ne dam doar cu parerea

Am puso pe op-com si imi doar cand vrea ea erroare la Egr, am scos egr lam curat lam mangaiat si tot asa face, zic ca da erroarea doar cand vrea ea pentru ca de exemplu am puso pe op-com cand am pornito si am mers ceva cu masina si cand a facut faza aia nu mia dat nici o erroare, erroarea mia iesit cand am oprit masina am pornito si am dat sa plec cu masina mia aparut erroare, erroarea este asta . P0400

PS: si ce scrie in descriere la erroare sa inteleg ca aia e piesa care da eroarea ¿nu? La tine ce a fost?
Uitasem ca iam facut o poza cand am vazut eroarea scrie asa:
P0400 Not Present
( 5 ) Critical system malfunction 2 (refer to cheching procedure: trouble code description)

EGR`ul.
Type Powertrain - Auxiliary Emission Controls - ISO/SAE Controlled
Description

EGR System Performance Conditions
Cause

DTC P0107, P0108, P0112, P0113, P0117, P0118, P0122, P0123, P0601, P0718 and P0724 not set, ECT input above 81°F, engine speed 500-900 rpm, BARO input above 95 kPa, MAP input below 24 kPa, IAC counts steady, no A/C Clutch, Brake switch or TCC transitions, VSS input above 14 mph, then during these Decel Mode Test conditions (throttle angle below 1%, not in DFCO, EGR duty cycle at 0%, then with the EGR solenoid enabled), the PCM detected that the change in the MAP sensor input was less than a predetermined amount stored in memory

P0400 - Exhaust Gas Recirculation Flow Malfunction
OBD-II Trouble Code Technical Description

Exhaust Gas Recirculation Flow Malfunction
What does that mean?

The exhaust gas recirculation (EGR) valve is vacuum controlled valve that regulates the amount of exhaust gases that re-enter the cylinders. The powertrain control module (PCM) determines how much based on engine load, temp, and other conditions. If the PCM detects that the amount of exhaust gases entering the cylinder were insufficient or non-existent, this code is set.
Symptoms

No symptoms will likely be noticed by the driver other than the MIL (malfunction indicator lamp). However, non visible symptoms will be increased combustion temperature and increased Nox emissions.
Causes

A code P0400 may mean that one or more of the following has happened:

Plugged EGR passage which restricts the flow of exhaust gasses
Faulty EGR solenoid
Faulty EGR solenoid wiring/harness
Vacuum lines damaged/disconnected to the EGR valve solenoid or to the EGR valve
Faulty EGR valve

Possible Solutions

Since EGR valve designs are different, no one test will suffice:

Using a scan tool, operate the EGR valve with the engine running. If the engine stumbles, the problem was likely intermittent wiring problem or intermittent blockage problem
If engine doesn't stumble, operate the EGR valve manually, if possible. If engine doesn't stumble and die, the ports are likely plugged. Removal of valve and cleaning of all ports will be required
Checking of solenoid can only usually be done with a scan tool, because most solenoids operate with a duty cycle of voltage, rather than constant voltage
Check all vacuum lines, hoses, etc for any damage
Visually inspect the solenoid harness and the solenoid for damage
Replace EGR valve

E consum de domnisoara...

Se poate si la Marius sa aiba aceiasi eroare!

La P0400 se verifica tot plecand de la pompa de vacuum : pompa , traseu vacuum , electrovalve (EGR , swirl , turbo) , capsula vacumatica de la swirl , wg (sa fie tija trasa la maxim la pornire) , EGR (curatare + sa nu aiba membrana sparta) , coturile de cauciuc. Spor!

Daca tot am deskis postu asta vreau sa va intreb cum se skimba becu de la check engine? ca la mine vad ca nu mai se aprinde nici cand pun contactu.

(aici se vede clar ca nu se aprinde, vreau sa va arat treaba aia ca nu trece de 4.000), aici era apa sub 70 grade


Iar aici cand am ajuns in garaj dupa 10-15 min (4-6 KM) bine ca nici nu ajunge la 4.000 rpm



Am desfacut kilometraju dar nam dat de becuri alea ( check engine, ABS...etc) se pot skimba becurile alea?

Mersi o sa incerc sal vad (fara sa nu rup ceva) ;P , maine o sa ma pun sa verific toate furtunasele tot tot sa vad daca ii dau de cap , ca deja ma dispera
