Coduri de eroare

[valy210988]

Rog pe cineva care stie sa-mi spuna si mie ce reprezinta codul de eroare B1025(Comunicare CAN disturbata cu SIH)
Multumesc frumos!

[Mercedes-cdi]

Presiunea calculata de ECM la valoarea din galerie nu corespunde cu presiunea pe care o dezvolta Turbina. Posibile cause mecanice sau electrice ce detin defectiuni la diferite componente.

Salut, am un C class W203, 200 CDI din 2004, si se plafoneaza la 3000 RPM, la tester am fost si ii dadea eroare P0105, sensor presiune, l-am schimbat si aceeasi eroare. Va rog, ce as mai putea verifica la ea ? mutlumesc

Multumesc din suflet. Mai detaliat de atata nici ca se putea...o sa pun in practica pasii trimisi, mersi. Sa auzim de bine

Generic OBD Error Code Details for P0105
Manifold Absolute Pressure/Barometric Pressure Circuit
What does this mean?
OBD Code P0105refers to
The MAP (Manifold Absolute Pressure) sensor is part of the fuel management system. It reacts to changes in engine manifold pressure. The PCM (Powertrain Control Module) monitors the MAP sensor continually to properly run the engine. Changes in engine load require changes in the amount of fuel injected, and timing of the ignition system, etc. An engine under load has more manifold pressure(or less vacuum) than an engine that is coasting. As the load changes, the MAP sensor voltage signal to the PCM changes accordingly. To check the MAP sensor operation, though, the PCM watches other sensors to verify that the MAP sensor is working properly. For example, the PCM compares the TPS (Throttle Position Sensor) signal to the MAP signal to verify the MAP signal isn't "sticking". If the PCM doesn't see a MAP sensor change immediately follow a change in the throttle pedal sensor, it knows there is a problem with the MAP sensor and sets P0105. Or, if the PCM notices that the TPS indicates the engine is under load, but the MAP signal indicates that the engine is "coasting" it, again, knows there is a problem with the MAP sensor or TPS and sets P0105.
Symptoms
Possible sumptoms of OBD code P0105
Poor running engine Engine runs rich Engine won't idle Engine backfires through tailpipe Engine misfire under load or at idle MIL (Malfunction Indicator Lamp) illumination In some extreme cases there may be no symptoms other than MIL illumination
Causes
Possible causes of OBD code P0105
MAP sensor vacuum hose disconnected or plugged Bad MAP sensor Bad TPS Damaged or problematic MAP sensor connector Damaged or problematic TPS connector Damaged wiring Short to reference voltage on signal circuit of MAP sensor Loss of ground to MAP sensor or TPS Open on signal circuit of MAP sensor Bad PCM
Possible Solutions
Using a scanner or code reader, turn the ignition on and engine OFF; what does the MAP sensor voltage read? It should be about 4 Volts for sea level. If you are at a higher altitude, it should decrease about half a volt or so for each 1,000 ft. of altitude (this will vary from model to model) Or if you have a separate MAF (Mass air flow) sensor on your vehicle, they are usually equipped with a Barometric pressure reading. If so, the Baro reading should match the MAP reading (they both measure ambient air pressure). If they're roughly equal, then, check for Freeze Frame data of the MAP sensor (if available). NOTE: Freeze Frame data is the PCM recording a fault when it happens. It captures the readings of the various PIDS (parameter identifiers)available to troubleshoot what happened. It's like a recording of the problem as it happened. At idle a typical MAP sensor Voltage reading should be about a volt, and at WOT (wide open throttle) it should approach 4.5 to 5 Volts. As for the TPS, at idle, the voltage reading is about 1 Volt or less. As the throttle is opened the reading will increase to 4.5 Volts at WOT. Do the two readings make sense? For example, if the TPS reading on Freeze Frame data shows 2.5 Volts (indicating partial throttle) does the MAP sensor indicate a reading that isn't at either extreme? Using the Freeze Frame data (if available) compare the MAP reading to the TPS when the problem occurred. This can help you identify what happened If you have no access to Freeze Frame data then check if the MAP sensor voltage changes when you apply vacuum to it. You can do this by mouth or a vacuum pump. The voltage should increase as you apply vacuum. If the reading doesn't change as you apply vacuum, make sure there are no obstructions in the hose to the sensor. If the hose is clear, the MAP sensor is usually bad, but it doesn't rule out the following from causing the problem: Does the MAP sensor appear to be stuck at less than .5 Volts? Then: NOTE: This code shouldn't set if the MAP is stuck at extremely low voltage, however, I'm adding it in because there's no way to know for certain for which vehicles a low voltage condition may set a P0105. Inspect the wiring harness and MAP sensor connector. Repair any damage Unplug the MAP sensor connector. Also, at the PCM connector, remove the MAP sensor signal wire and check for continuity to the MAP sensor connector. If there is infinite resistance, then repair open in MAP signal circuit. If the signal wire has continuity to the MAP sensor connector, then check for 5 volt reference voltage to the connector and a good ground. If both are present, then re-install all removed wiring and replace the MAP sensor. Does the MAP sensor appear to be stuck at full 4.5 voltage? Then: Inspect the wiring harness for damage. Repair as needed Remove the MAP sensor signal wire from the PCM connector. With a voltmeter measure the voltage with KEY ON ENGINE OFF. Is there 4.5 Volts? If so, unplug the MAP sensor and recheck. If it is still present, then repair short between the signal wire and 5 volt reference wire. If unplugging the MAP sensor causes the voltage to disappear, check that the ground is intact. If it is, then replace the MAP sensor due to internal short.

Pune masina pe Star si vezi ce eroare da.
In cel mai fericit caz este defect unul din senzorii de Abs.

erori abs esp bas

va salut sunt nou pe forum.am un C220 cdi 116 cai 2001 si am 3 martori aprinsi n bord abs esp bas.am scimbat discurile placheti de frana rulmenti simering pe fata am mai schimbat comutatorul de sub pedala de frana si degeaba tot imi apar erorile astea astept parerile voastre multumesc,

Eu astept ca, inainte de a posta, sa parcurgi regulamentul.

[Curvar ucenic]

Dati-mi cod defect si tip motor (exact cum scrie pe ecran cind bagati la tester)
ca sa-mi dau seama ce are.

Salut, wdb 2102161b032036 , 210.216

Erori:
B1416 ==pompa asta am demontat am verificat invarte(direct de la baterie cel putin).

B1422 ==aici nu prea inteleg, ceva intre afisaj bord si alea de unde controlezi temperatura interioara cu doua rotite, cald rece.

B1813 ==sirocoul -am citit ca pleaca in unele cazuri la anumite temperaturi poate daca se rezolva B1422 porneste sirocoul?

B1800 ==tot sirocoul, restart , nu da flacara

Pentru B1422 sa incerc cu alt bord sau cu alt modul al controlului temperaturii?

Multumesc anticipat !

poate cineve sa dea detalii despre reteaua CAN si daca o defectiune de comunicare a acesteia poate scoate din functie vreun modul de control sau altceva ?

[boro_little]

salut!Am un c200 kompressor din 2000. in bord apar 3 fault-uri: ABS ESP BAS. pe tester a iesit cod 1025. Deasemenea nu face niciun pic de caldura.

[Mercedes-cdi]

Astea sint coduri defect specific fabricant. Adica nu se pot vedea si talmacii decit cind masina este pe tester. La testerul meu eu mi-as da seama.

Imi zici si mie te rog daca gasesti eroarea : P1227 (EPC)
Mersi mult!

[Mercedes-cdi]

Eu as fi al 11-lea. Dar sper sa fiu ultiumul.
Daca v-as zice ce spune fabricatul pentru ultima generatie de turbine cred ca ati face infart.
In orice caz, ca sa nu fac vreo confuzie. Dati-mi serie de sasiu si tipul de motor sa vad despre ce este vorba.

salutare. am un sprinter modelul nou, 313 si nu imi mai intra turbinele in functiune (merge doar in puterea motorului). i-am facut o diagnoza si imi da urmatoarele probleme: Y 31/14 BOOST PRESSURE CONTROL / PRESSURE TRANSDUCER. si Y 77 WASTE GATE PRESSURE TRANSDUCER. ma poate sfatui cineva unde anume sa umblu la masina? am fost la 10 meseriasi si cam toti mi-au dat opinii diferite. nu as vrea sa desfac tot motorul pentru mai stiu eu ce problema de vacum sau cine stie ce.... va multumesc anticipat.

tot ce stiu e ca tijele de la turbine functioneaza, supapele de vacum la fel. erorile aparute sunt alea pe care le-am scris. le-am notat si eu cand mi-a facut un meserias diagnoza.masina e m.b. 906ka35 versiunea Lma31350e, motor 2148 cm3, diesel L766*01, 95 kw. SA MA INDREPT SPRE DEBITMETRUL DE AER ????? multumesc.
