P228B e bolelang?

Khoutu ena ea Mathata a Tlhatlhobo (DTC) ke khoutu ea phetisetso e akaretsang mme e sebetsa ho likoloi tse ngata tsa OBD-II (1996 le tse ncha). Sena se ka kenyelletsa, empa ha se felle ho Volkswagen, GMC, Chevrolet, Cadillac, Ford, BMW, jj. Leha e le sebopeho sa kakaretso, mehato e nepahetseng ea ho lokisa e ka fapana ho latela selemo sa mohlala, sebopeho, phetisetso le phetiso.

Ka boiphihlelo ba ka ba tlhahlobo ea P228B, e sebelisitsoe feela likoloi tsa disele. Ho ne ho boetse ho bolela hore module ea taolo ea powertrain (PCM) e fumane khatello e fetelletseng ea khatello ea mafura ho taolo ea khatello ea mafura ea elektroniki, e matla ka ho lekana ho tiisa hore enjine e koaloe.

Molaoli eo ho buuoang ka eena o ne a khethiloe palo ea 2. Lits'ebetsong tse sebelisang taolo e mengata ea khatello ea mafura ea elektroniki, ho sebelisoa nomoro khafetsa. Nomoro ea 2 e ka supa mochini o itseng oa enjene. Lekola litlhaloso tsa moetsi oa koloi eo ho buuoang ka eona. Sisteme e phahameng ea khatello ea disele e tlameha ho sebetsoa ke basebetsi ba tšoanelehang FEELA.

PCM (kapa mofuta o mong oa taolo e kopaneng ea mafura a disele) e lekola / e laola taolo ea khatello ea mafura ea elektroniki. Ha PCM e sebelisa kenyelletso e tsoang mochineng oa khatello ea mafura (o ka hara seporo sa injector ea mafura), e lula e fetola matla a khatello ea khatello ha enjene e ntse e sebetsa. Matla a betri le li-sign tsa lefats'e li sebelisetsoa ho laola servomotor (ho khatello ea mafura), e etsang hore valve e sebelisoe ho netefatsa hore boemo ba khatello ea mafura bo a fumaneha maemong afe kapa afe.

Ha motlakase o kenang ho servo motor ea motlakase oa khatello ea mafura o eketseha, valve e ea buleha 'me khatello ea mafura ea eketseha. Ho se sebetse ha servo ho etsa hore valve e koaloe le khatello ea mafura e theohe. Taolo ea khatello ea mafura le sensor ea khatello ea mafura hangata li kopantsoe ntlong e le 'ngoe (e nang le sehokedi se le seng sa motlakase), empa hape e ka ba likarolo tse arohaneng.

Haeba PCM e fumana hore khatello ea mafura ea taolo ea 2 ea taolo ea motlakase e kantle ho parameter e itseng (e baloang ke PCM), P228B e tla bolokoa 'me lebone la sesupo sa ho se sebetse (MIL) le ka bonesa. Ho kanna ha etsahala hore ho koaloa ha enjene e qobelloang ho tla etsahala.

Boima ba DTC ee ke bofe?

Kaha khatello ea mafura le khatello e ka baka tšenyo ea ka hare ho enjine le sesebelisoa se fetolang lintho 'me ea baka mathata a fapaneng a ho sebetsana, khoutu P228B e lokela ho khetholloa e le e tebileng.

A mang a matšoao a khoutu ke afe?

Matšoao a P228B DTC a ka kenyelletsa:

• Ha ho na boemo ba thunye
• Likhoutu tsa enjene tsa misfire le likhoutu tse sa sebetseng tsa taolo ea lebelo le tsona li ka tsamaea le P228B.
• Phokotso ea peterole
• Ho lieha ho qala ha enjene e bata
• Mosi o motšo o tsoang tsamaisong ea ho qeta

A mang a mabaka a tloaelehileng a khoutu ke afe?

Mabaka a khoutu ena a ka kenyelletsa:

• Boemo bo tlase ba khatello ea oli / enjene
• Enjene e sa lebelloang
• Sephahla sa khatello ea mafura se nang le phoso
• Taolo ea khatello ea mafura e nang le phoso
• Potoloho e khuts'oane kapa e buletsoe ka wiring le / kapa likhokahanong tsa taolo ea taolo ea khatello ea mafura
• Phoso e mpe ea mananeo a PCM kapa PCM

Ke mehato efe e meng ea ho rarolla bothata ba P228B?

O tla hloka sekena sa tlhahlobo, digital volt / ohmmeter (DVOM), le mohloli o tšepahalang oa tlhaiso-leseling ea makoloi ho fumana khoutu ea P228B ka nepo.

O ka boloka nako ka ho batla Technical Service Bulletins (TSBs) e hlahisang khoutu e bolokiloeng, koloi (selemo, make, model le enjene) le matšoao a fumanoeng. Tlhahisoleseling ena e ka fumanoa mohloling oa tlhaiso-leseling ea koloi ea hau. Haeba u fumana TSB e nepahetseng, e ka lokisa bothata ba hau kapele.

Kamora hore o hoketse sekena koung ea tlhahlobo ea koloi le ho fumana likhoutu tsohle tse bolokiloeng le data e tsamaeang le foreimi, ngola tlhaiso-leseling (haeba khoutu e ka ba ea nakoana). Kamora moo, hlakola likhoutu le teko ho khanna koloi ho fihlela e 'ngoe ea lintho tse peli e etsahala; khoutu e khutlisitsoe kapa PCM e kena ka mokhoa o loketseng.

Khoutu e kanna ea ba thata le ho feta ho fumana haeba PCM e kena ka mokhoa o loketseng hona joale hobane khoutu e bohareng. Boemo bo lebisitseng polokelong ea P228B bo kanna ba hloka ho mpefala pele ho ka fumanoa tlhahlobo e nepahetseng. Haeba khoutu e khutlisitsoe, tsoela pele ho hlahloba.

U ka fumana maikutlo a sehokedi, li-pinout tsa sehokedi, libaka tsa likarolo, lits'oants'o tsa wiring, le lits'oants'o tsa block diagnostic (tse amanang le khoutu le koloi eo ho buuoang ka eona) u sebelisa mohloli oa tlhaiso-leseling ea koloi.

Hlahloba ka mahlo lithapo le likhokelo tse amanang. Lokisa kapa kenya mohala o sehiloeng, o chesitsoeng kapa o senyehileng.

Sebelisa DVOM ho leka matla a potoloho ea motlakase le ea mobu ho elektroniki regulator (2) le li-sensor tsa khatello ea mafura. Haeba ho se na voltage e fumanehang, hlahloba li-fuse tsa sisteme. Kenya sebaka sa li-fuse tse fefotsoeng kapa tse senyehileng ha ho hlokahala 'me u li hlahlobe bocha.

Haeba motlakase o fumanoa, sheba potoloho e loketseng ho sehokedi sa PCM. Haeba ho sa fumanoe motlakase, belaella potoloho e bulehileng lipakeng tsa senotlolo seo ho buuoang ka sona le PCM. Haeba motlakase o fumanoa moo, belaella PCM e fosahetseng kapa phoso ea mananeo a PCM.

Lekola taolo ea khatello ea mafura le sensor ea khatello ea mafura le DVOM. Haeba efe kapa efe ea tsona e sa fihlelle litlhaloso tsa moetsi, e nke e le phoso.

Haeba molaoli oa mafura (2) le li-sensor li sebetsa hantle, sebelisa gauge e ts'oeroeng ka letsoho ho lekola khatello ea mafura seporong ho hlahisa boemo ba ho hloleha.

• Terene ea peterole le likarolo tse amanang le eona li ka ba tlas'a khatello e matla (haholo).
• E-ba hlokolosi ha u tlosa sensor ea khatello ea mafura kapa taolo ea khatello ea mafura.
• Cheke ea khatello ea mafura e tlameha ho etsoa ha ho khantsoe mollo le senotlolo ha enjene e tima (KOEO).

U hloka thuso e eketsehileng ka khoutu ea hau ea P228B?

Haeba o ntse o hloka thuso ka DTC P228B, beha potso litlatsong tse ka tlase ho sengoloa sena.
