P2149 Fuel Injector Group B Ukungasebenzi / Okuvulekile

P2149 Fuel Injector Group B Ukungasebenzi / Okuvulekile

Idatha ye-OBD-II DTC

I-Fuel Injector Group B Circuit / Open

Kusho ukuthini lokhu?

Le yikhodi enenkinga yokuxilonga i-powertrain (DTC) ejwayelekile futhi isetshenziswa kakhulu ezimotweni ze-OBD-II. Lokhu kungabandakanya kepha akukhawulelwe ezimotweni ezisuka eDodge Ram (Cummins), GMC Chevrolet (Duramax), VW, Audi, Ford (Powerstroke), Mercedes Sprinter, Peugeot, Alfa Romeo, Nissan, Saab, Mitsubishi, njll. zingahluka ngokuya ngonyaka wokwenziwa, ukwenziwa, imodeli nokudluliswa kokudluliswa.

Ama-injection ephethiloli ayingxenye ebalulekile yezinhlelo zokulethwa kukaphethiloli ezimotweni zesimanje.

Izinhlelo zokulethwa kukaphethiloli zisebenzisa inani elihlukile lezinto ukulawula nokuqapha ivolumu, isikhathi, ingcindezi, njll. Amasistimu ahlanganiswe ne-ECM (Injini Yokulawula Injini). Imijovo ye-Fuel yethulwa njengezothatha indawo ye-carburetor ngoba ama-injector ayasebenza futhi asebenza kahle ekuphatheni ukulethwa kukaphethiloli. Ngenxa yalokhu, bathuthukise ukusebenza kwethu kahle kukaphethiloli, futhi onjiniyela bakha ngenkuthalo izindlela ezinhle kakhulu zokwenza ngcono ukusebenza kahle kwalo mklamo.

Njengoba kunikezwe iqiniso lokuthi i-atomization ye-injector ilawulwa ngogesi, i-voltage yokuhlinzeka ibalulekile ekulethweni kukaphethiloli kumasilinda. Kodwa-ke, inkinga kulesi sifunda ingakwazi futhi / noma ibangele izinkinga ezinkulu zokuphatha phakathi kwezinye izingozi / izimpawu ezingaba khona.

Uhlamvu lweqembu "B" kule khodi lusetshenziselwa ukuhlukanisa ukuthi iphutha likusiphi isifunda. Ukunquma ukuthi lokhu kusebenza kanjani emotweni yakho ethize, udinga ukuxhumana nemininingwane yezobuchwepheshe yomkhiqizi. Ezinye izibonelo zokungafani nemibhobho: ibhange 1, 2, njll.

I-ECM ikhanyisa isibani sesibonakaliso sokungasebenzi kahle (isibani sokungasebenzi kahle) ngekhodi engu-P2149 kanye / noma amakhodi ahlobene (P2150, P2151) lapho ihlola inkinga kumandla okuhambisa ama-fuel injectors kanye / noma kumasekethe awo. Kumele kuqashelwe ukuthi amahanisi we-injector fuel ahanjiswa eduze kwamazinga okushisa aphezulu. Ngenxa yokutholakala kwamabhande, awekho ukumelana nokulimala komzimba. Ngalokhu engqondweni, ngizothi ezimweni eziningi kuzoba yinkinga yemishini.

Isekhethi / isekethe evulekile ye-P2149 Group B iyasebenza lapho i-ECM ithola ukuvuleka noma ukungasebenzi kahle kumjikelezo we-fuel injector supply voltage circuit.

Buyini ubunzima bale DTC?

Nginobuhle, ngingasho. Ensimini, sikubiza ngokungabi bikho kukaphethiloli enhlanganisweni ebaswe yisimo "esinciphile". Lapho injini yakho isebenza engxenyeni engenamafutha, ubeka engcupheni yokudala ukulimala okukhulu kwenjini esikhathini esizayo esiseduze nakude. Unalokhu engqondweni, hlala unakekela ukugcinwa kwenjini yakho. Kukhona ukukhuthala lapha, ngakho-ke masigcine izinjini zethu zihamba kahle futhi kahle. Ngemuva kwakho konke, badonsa isisindo sethu ukusithutha nsuku zonke.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenkinga ye-P2149 zingafaka:

• Ukusebenza kwenjini okungazinzile
• Ngenelisa
• Ukwehla komnotho kaphethiloli
• Idle engazinzile
• Intuthu eyeqile
• Imisindo yenjini
• Ukuntuleka kwamandla
• Ayikwazi ukukhuphuka izintaba eziphakeme
• Impendulo encishisiwe yokuphendula

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi ye-P2149 ye-fuel injector group supply code ingafaka:

• Ama-injektha kaphethiloli anephutha noma alimele
• Izintambo zezintambo ezonakele
• Ukungasebenzi kahle kwentambo yangaphakathi
• Inkinga ye-ECM yangaphakathi
• Inkinga yesixhumi

Yiziphi ezinye zezinyathelo zokuxazulula inkinga nge-P2149?

Isinyathelo esiyisisekelo # 1

Isinyathelo sokuqala esinconyiwe ukunquma ukuthi iyiphi "iqembu" lezinzwa umkhiqizi akhuluma ngazo. Ngalolu lwazi, uzokwazi ukuthola indawo engokoqobo ye-injector(ama) kanye namasekhethi awo. Lokhu kungase kudinge ukususwa kwamakhava enjini amaningi kanye/noma izingxenye ukuze uthole ukufinyelela okubonakalayo (uma kungenzeka). Qiniseka ukuthi ubheka izintambo zokubopha izintambo eziphukile. Noma yikuphi ukuvala okugugile kufanele kulungiswe kahle ngamashubhu ashwabanisa ukushisa ukuze kuvinjelwe izinkinga eziqhubekayo kanye/noma zesikhathi esizayo.

Isinyathelo esiyisisekelo # 2

Kwesinye isikhathi amanzi kanye / noma uketshezi kungabambeka ezigodini lapho kufakwa khona imibhobho. Lokhu kwandisa amathuba okuthi izixhumi zenzwa, phakathi kokunye ukuxhumana kagesi, zikhule ngokushesha okukhulu kunokujwayelekile. Qiniseka ukuthi konke kuhlelekile futhi amathebhu ezixhumi akuvala ngokufanele ukuxhumana. Zizwe ukhululekile ukusebenzisa uhlobo oluthile lokuhlanza oxhumana kagesi ukugcina konke kungena kuphume ngaphandle, ingasaphathwa eyokwanda kokuxhuma kukagesi ekuxhumaneni usebenzisa lo mkhiqizo.

Isinyathelo esiyisisekelo # 3

Hlola ukuqhubeka ngokulandela izinyathelo zokuxazulula inkinga kumanuwali yakho yesevisi yemoto. Isibonelo esisodwa ukukhipha i-voltage yokuhlinzeka kusuka ku-ECM ne-injector fuel bese usebenzisa i-multimeter ukuthola ukuthi izintambo zisebenza kahle yini.

Ukuhlola okukodwa engikuthandayo ukuze nginqume ngokushesha ukuthi ingabe kukhona okuvuliwe ocingweni oluthile olungasiza ngekhodi P2149 ukwenza "ukuhlolwa kokuqhubekayo". Setha i-multimeter ukuze ithi RESISTANCE (ebuye yaziwe ngokuthi ama-ohms, impedance, njll.), thinta isiphetho esisodwa uye ekugcineni kwesinye sesekhethi, kanti esinye isiphetho siye kwesinye. Noma yiliphi inani elingaphezu kwalokho elifunwayo lingabonisa inkinga kusekethe. Noma iyiphi inkinga lapha izodinga ukucaciswa ngokulandela ucingo oluthile oluxilongayo.
