Khoutu ea phoso e tebile hakae? P0749?

Khoutu ea mathata P0749 e bonts'a bothata ka mochini oa phetisetso oa khatello ea mokelikeli oa solenoid. Le hoja sena e se ho hlōleha ha bohlokoa, ho ka baka mathata a tebileng ka phetisetso le ho ama ts'ebetso ea eona le ho tšoarella ha eona.

Khatello ea mokelikeli o fokolang kapa o sa lekaneng o bakoang ke valve ea solenoid e fosahetseng e ka lebisa ho senyeha ha maemo, ho eketsa ho apara likarolo tsa phetisetso, esita le ho hlōleha ka lebaka la ho chesa kapa ho se sebetse hantle. Ho feta moo, mathata a phetisetso a ka fokotsa polokeho le ts'ebetso ea koloi ka kakaretso.

Ka kakaretso, leha P0749 e se phoso e bolaeang, e hloka tlhokomelo e hlokolosi le ho lokisoa ka nako ho qoba mathata a tebileng a phetisetso le ho netefatsa koloi e bolokehileng le e tšepahalang.

Ke tokiso efe e tla thusa ho felisa khoutu? P0749?

Ho ka hlokahala mehato e latelang ea tokiso ho rarolla DTC P0749:

1. Ho fetola Valve ea Solenoid ea Khatello ea Khatello: Haeba bothata bo bakoa ke hore valve ka boeona ha e sebetse hantle, e lokela ho nkeloa sebaka. Ha u fetola valve, ke habohlokoa ho netefatsa hore valve e ncha e kopana le litlhaloso tsa moetsi 'me e kenngoa ka nepo.
2. Ho lokisa kapa ho nchafatsa likhokelo tsa motlakase le lithapo: Haeba bothata bo bakoa ke puisano e sa lokelang kapa mathata a motlakase potolohong ea taolo, joale likhokahano tse senyehileng kapa lithapo li tlameha ho hlahlojoa 'me, ha ho hlokahala, li lokisoe kapa li nkeloe sebaka.
3. Ho hlahloba le ho lokisa likarolo tse ling tsa phetiso: Ka linako tse ling bothata bo ka 'na ba se ke ba e-ba le valve ea solenoid feela, empa hape le likarolo tse ling tsa phetisetso tse kang li-sensor tsa khatello kapa mochine oa ho laola phetiso (TCM). Ka mor'a ho hlahlojoa ka botlalo, likarolo tsena li lokela ho lokisoa kapa ho nkeloa sebaka.
4. Tlhokomelo ea mokelikeli oa phetiso le ho nchafatsoa: Haeba ho khoneha, ho boetse ho kgothaletswa ho fetola mokelikeli wa phetiso le sefe. Sena se ka thusa ho ntlafatsa ts'ebetso ea phetisetso le ho thibela mathata ho hlaha hape.
