Potoloho "A" ea taolo ea turbocharger / supercharger boost, lets'oao le phahameng

See se bolela eng?

Khoutu ea Mathata a Tlhatlhobo (DTC) ke khoutu ea phetisetso e akaretsang, ho bolelang hore e sebetsa ho likoloi tse hlomelitsoeng tsa OBD-II tse nang le supercharger kapa turbocharger (Toyota, GMC Chevrolet Duramax, Mazda, Chrysler, Jeep, Ford Powerstroke, jj.).) . Leha e le ka tlhaho ka tlhaho, mehato e ikhethileng ea ho lokisa e ka fapana ho latela mofuta / mofuta.

Li-turbocharger le li-supercharger ke lipompo tsa moea tse qobellang moea ho kena enjeneng ho eketsa matla. Li-supercharger li khannoa ho tloha crankshaft ea enjene ka lebanta, ha li-turbocharger li khannoa ke likhase tsa enjene ea mouoane.

Likoloi tse ngata tsa sejoale-joale tse sebelisang turbocharger li sebelisa se bitsoang variable geometry turbocharger (VGT). Mofuta ona oa turbocharger o na le makhasi a fetolehang ka ntle ho turbine e ka buloang le ho koaloa ho fapana boholo ba khatello ea khatello. Sena se lumella turbo hore e laoloe ntle le lebelo la enjene. Hangata li-van li buleha ha enjene e le tlasa mojaro o bobebe ebe e buloa ha mojaro o eketseha. Sebaka sa lehare se laoloa ke module ea taolo ea powertrain (PCM), hangata e sebelisang motlakase oa motlakase kapa motlakase. Boemo ba turbocharger bo ikemiselitse ho sebelisa sensor e ikhethang ea boemo.

Likoloing tse sebelisang turbocharger kapa mohala o fetisisang o fetotsoeng moetlo, matlafatso a laoloa ka litšila kapa litšila. Valve ena e bula ho hlahisa khatello ea matlafatso. PCM e lekola sistimi ena ka sensor ea khatello e matlafatsang.

Bakeng sa DTC ena, "A" e bontša bothata karolong e 'ngoe ea potoloho ea sistimi eseng letšoao kapa karolo e itseng.

Khoutu P0048 e behiloe ha PCM e fana ka lets'oao le phahameng la taolo ea matlafatso, ebang enjene e sebelisa turbocharging ea VGT kapa turbocharger / supercharger ea setso.

Ho tiea ha khoutu le matšoao

Bohloko ba likhoutu tsena bo mahareng ho isa ho bo matla. Maemong a mang, mathata a turbocharger/supercharger a ka baka tšenyo e kholo ea enjine. Ho khothalletsoa ho lokisa khoutu ena kapele kamoo ho ka khonehang.

Matšoao a khoutu ea P0048 a ka kenyelletsa:

• Ho potlakisa ho feteletseng ho fella ka ho kokota le ho ka senyeha ha enjene
• Sheba Leseli la Enjene

mabaka a

Mabaka a ka bang teng a ho beha khoutu ena:

• Boima bo matla ba khatello / khatello ea boemo ba turbocharger
• Turbocharger / supercharger e haelloang
• Phoso solenoid taolo
• Mathata a wiring
• PCM e nang le phoso
• Hlahisa lephaka haeba belofo e laoloa ke lephaka

Mekhoa ea ho hlahloba le ho lokisa

Qala ka ho lekola sistimi ea taolo ea turbocharger le turbocharger. Batla likhokahano tse hlephileng, likhoele tse senyehileng, ho tsoa hoa vacuum, jj. Ebe o sheba li-bulletins tsa lits'ebeletso tsa tekheniki (TSB) mabapi le bothata. Haeba ho se letho le fumanoang, o tla hloka ho fetela ho li-diagnostics tsa sistimi ka mehato.

E latelang ke ts'ebetso e akaretsang ha tlhahlobo ea khoutu ena e fapana le koloi le koloi. Ho lekola sistimi ka nepo, o hloka ho sheba sethala sa "diagnostic flow" sa moetsi.

Netefatsa ts'ebetso ea sistimi ka ho laela solenoid ea taolo hore e behe bocha ka sesebelisoa sa lisebelisoa tsa mahlakore a mabeli. Phahamisa lebelo la enjene ho fihla ho e ka bang 1,200 rpm ebe o tima le ho tima enjene ea motlakase. Sena se lokela ho fetola enjene RPM mme sesebelisoa sa scan ninemanga sa PID se lokela ho fetoha. Haeba lebelo le fetoha, empa boemo ba PID / khatello ea khatello ha e fetohe, belaela hore ho na le bothata ho sensor kapa potoloho ea eona. Haeba RPM e sa fetohe, belaela hore bothata bo ho solenoid ea taolo, turbocharger / supercharger, kapa wiring.

• Ho leka potoloho: hlahloba matla le mobu ho solenoid. Tlhokomeliso: Ha u etsa liteko tsena, solenoid e tlameha ho laeloa ON le sesebelisoa sa scan. Haeba ho se na matla kapa khokahano ea mobu, o tla hloka ho fumana sets'oants'o sa wiring ea fektheri ho fumana sesosa.
• Lekola turbocharger / supercharger: tlosa moea o kenang ho lekola turbocharger / supercharger bakeng sa tšenyo kapa maloanlahla. Haeba tšenyo e fumanoa, nka sebaka sa yuniti.
• Hlahloba boemo / khatello ea senotlolo le potoloho: maemong a mangata mehala e meraro e lokela ho hokahanngoa le sensor ea boemo: matla, mobu le lets'oao. Netefatsa hore ba bararo ba teng.
• Hlahloba solenoid ea taolo. Sheba Tlhahisoleseling ea Ho Lokisa Fektheri bakeng sa lintlha. U ka hokela solenoid ho matla le mobu ho lekola haeba e ea sebetsa.
