Ho qeta khatello ea mocheso oa mocheso oa khase

Khoutu ea phoso e bolela eng P0470?

Khoutu ena e akaretsang ea mathata a tlhahlobo e sebetsa ho mefuta e fapaneng ea likoloi, ho kenyeletsoa Ford, Mercedes le Nissan, tse nang le mefuta e fapaneng ea lienjineri, ho kenyeletsoa peterole le diesel, ho qala ka 2005. E amana le khatello ea khase ea ho qeta 'me e ka bontša bothata ba motlakase kapa mochine. Ka linako tse ling e ka tsamaisana le khoutu ea P0471, e fapaneng ka nako le mofuta oa ho hloleha ha sensor ea khatello ea ho tima. Mehato ea ho lokisa e itšetlehile ka moetsi, mofuta oa mafura le 'mala oa terata.

Khoutu ea mathata P0470 e tloaelehile ho mefuta e fapaneng ea likoloi le mefuta ea likoloi. E bontša bothata ka mochine oa khatello ea khase ea ho qeta 'me e ka ba ka lebaka la mathata a motlakase kapa a mechine. Ka linako tse ling e tsamaisana le khoutu ea P0471, e fapaneng ka nako ea bothata le mofuta oa ho hloleha ha sensor. Mehato ea ho lokisa e ka fapana ho latela moetsi, mofuta oa mafura le 'mala oa terata.

Sensor ea Exhaust Back Pressure (EBP) e phetha karolo ea bohlokoa ho lekanya khatello ea khase ea ho tsoa 'me e lumella taolo ea Exhaust Back Pressure Regulator (EPR) ka taelo e tsoang ho Engine Control Module (ECM).

Mokhoa oa ho fumana khoutu ea phoso P0470?

Mokhoa o motle oa ho qala ho fumana khoutu ea P0470 ke ho hlahloba Tekheniki ea Tšebeletso Bulletin (TSB) bakeng sa mofuta oa koloi ea hau. Moetsi a ka fana ka ntlafatso ea software (firmware) bakeng sa PCM ho lokisa bothata bona. Ka mor'a moo, fumana sensor ea khatello ea khase koloing ea hau 'me u hakolle thapo e e hokahanyang le mokelikeli o mongata oa motlakase.

Leka ho tlosa khabone leha e le efe e ka 'nang ea baka khoutu ea P0470. Haeba tube e hloekile, hlahloba lihokelo le likhoele bakeng sa tšenyo kapa ho bola. Ka mor'a moo, leka matla a 5V le li-circuits tsa signal sensor u sebelisa digital volt-ohmmeter (DVOM).

Etsa bonnete ba hore sensor e tsitsitse hantle. Haeba liteko tsohle li feta, ho ka 'na ha hlokahala hore ho nkeloe sebaka sa sensor ea khatello ea khase e tsoang. Haeba khoutu ea P0470 e ntse e tsoela pele ho hlaha, PCM e fosahetseng e ka boela ea e-ba sesosa, empa e ka tlosoa feela ka mor'a ho nkela sensor sebaka le ho etsa liteko tse eketsehileng.

Liphoso tsa tlhahlobo

Lisosa tse ka bang teng tsa khoutu ea P0470

Ha u hlahloba khoutu ea P0470, ho bohlokoa ho nahana ka lisosa tse 'maloa tse ka lebisang khoutu ena. Ka tlaase ke lintlha tse ka sehloohong tse lokelang ho nahanoa:

  1. Thibelo ka har'a tube ho tloha ho manifold a mangata ho ea ho sensor ea khatello: Ntho e 'ngoe e ka etsahalang ke hore carbon e bokellana tsamaisong ea ho qeta, e ka bakang ho thibela tube eo mochine oa khatello o fumanang boitsebiso ka oona. Sena se ka baka 'malo o fosahetseng le khoutu ea P0470.
  2. Mathata ka sistimi ea exhaust gas recirculation (EGR), ho kenella ha moea kapa ho lutla ha moea: Mathata a ho qeta kapa mekhoa ea phepelo ea moea a ka ama khatello ea tsamaiso ea ho qeta 'me a baka khoutu ea P0470. Tlhahlobo e tšepahalang ea likarolo tsena e ka ba mohato oa bohlokoa.
  3. Ho se sebetse hantle ha sensor ea khatello ea khase ea exhaust: Mochine oa khatello ea khase ea khase ka boeona e ka 'na ea hlōleha kapa ea hlahisa matšoao a fosahetseng, e leng se hlahisang khoutu ea P0470.
  4. Mathata a Sensor ea Exhaust Back Back (EBP): Sensor ea ho qeta morao ke karolo ea bohlokoa ea tsamaiso ea tsamaiso ea enjene 'me e ka amahanngoa le khoutu ea P0470.

Lisosa tsena tse ka bang teng tsa khoutu ea P0470 li bohlokoa ho nahanoa nakong ea tlhahlobo le ho lokisoa ho supa le ho lokisa motso oa bothata.

Khoutu ea phoso e tebile hakae? P0470?

Khoutu ea mathata P0470 e bonts'a bothata ka sensor ea khatello ea khase e tsoang kapa khatello ea sistimi ea ho tima. Sena se ka ama ts'ebetso ea enjene, ts'ebetso le tšebeliso ea mafura. Leha sena e se ts'ohanyetso e mahlonoko, ke ts'ebetso e mpe e ka lebisang mathateng a tebileng ha e sa lokisoe. Ho khothaletsoa hore enjene ea hau e hlahlojoe le ho lokisoa ke mochine ha khoutu ea P0470 e bonahala e thibela ho senyeha ha enjene le ho boloka ts'ebetso ea enjene.

Ke tokiso efe e tla thusa ho felisa khoutu? P0470?

Ho rarolla khoutu ea P0470 ho kenyelletsa mehato e mengata, ho latela sesosa se khethiloeng:

  1. Ho hlahloba Lipuisano tsa Tšebeletso ea Teknoloji (TSB): Qala ka ho batla tlhahisoleseling ho li-bulletin tsa litšebeletso tsa tekheniki, tse ka bang le likhothaletso tsa moetsi bakeng sa ho rarolla bothata bona. Moetsi a ka fana ka mabone a PCM / reflashes a ka hlakola khoutu.
  2. Ho hlahloba sensor ea khatello ea exhaust: Tlosa sensor ea khatello ea khase ea exhaust 'me u hlahlobe hore na ho na le li-deposit tsa carbon kapa tse senyehileng. Hloekisa kapa u fetole sensor ha ho hlokahala.
  3. Tlhahlobo ea wiring: Lekola likhoele ka mahlo, sheba ho senyehile, ho bola kapa lithapo tse robehileng. Hakolla likhokahano 'me u li hloekise ha ho hlokahala.
  4. Ho hlahloba li-circuits tsa motlakase le matšoao: U sebelisa dijithale volt-ohm meter (DVOM), hlahloba matla a 5V le li-circuits tsa matšoao tse eang ho sensor. Etsa bonnete ba hore motlakase o kopana le litlhaloso tsa moetsi.
  5. Tlhahlobo ea ho qala: Lekola hore na sensor ea khatello ea khase ea exhaust e thehiloe hantle.
  6. Ho hlahloba tube le likhokahano: Lekola ka hloko tšupu e kopanyang turbocharger sebakeng se kenang ka bongata bakeng sa ho lutla.
  7. Ho hlakola liphoso: Sebelisa sekena sa OBD-II ho hlakola khoutu ea P0470 mohopolong oa PCM. Ka mor'a sena, khanna koloi 'me u hlahlobe hore na phoso e hlaha hape.
  8. Sensor e ncha: Haeba bothata bo ke ke ba rarolloa ka mekhoa e meng, nka sebaka sa sensor ea khatello ea khase ea ho tsoa.
  9. Tlhahlobo ea PCM: Haeba mehato eohle e ka holimo e sa rarolle bothata, ho ka 'na ha e-ba le bothata ka PCM. Leha ho le joalo, khetho ena e lokela ho nkoa feela e le mohloli oa ho qetela oa khetho.

Hopola hore tlhahlobo le tokiso li tlameha ho etsoa ke mochini o tšoanelehang kapa setsi sa litšebeletso ho netefatsa sesosa le tharollo e sebetsang ea khoutu ea P0470.
