P0477 - OBD-II Dambudziko Code Unyanzvi Tsananguro

Exhaust gas pressure control valve "A" yakaderera

Ko fault code inorevei P0477?

Dambudziko P0477 rine hukama nekushomeka kwemagetsi evharuvhu uye inogona kuitika pamhando dzakasiyana dzemotokari, kusanganisira Ford, Dodge, Mercedes, Nissan neVW. Iyi kodhi inoratidza voltage isiriyo iri kuverengwa neiyo exhaust gasi pressure sensor uye inotumirwa kune injini control module (PCM). Kana iyi voltage iri pasi peyakajairika, iyo PCM inochengeta kodhi P0477.

Iyo yekuburitsa backpressure valve inogadzirisa kupera kwemashure, iyo inobatsira kuwedzera kupisa kwemukati uye kuderedza windshield defrost nguva mune yakaderera ambient tembiricha. Iyo Engine Control Module (ECM) inoshandisa ruzivo nezve exhaust backpressure, tembiricha yemhepo yekudya, tembiricha yemafuta einjini, uye injini mutoro kudzora vharuvhu. Iyo valve inodzorwa kuburikidza ne12V inobuda dunhu mukati meECM.

Mumamiriro ekushisa akadzikama uye mamwe mamiriro ezvinhu, valve inogona kuramba yakavharwa zvishoma, zvichiita kuti mukati kupisa kupisa. Sezvo injini nemafuta zvichipisa, vharuvhu inogadzirisa kupera simba kumashure. Troubleshooting P0477 ingada kutarisa wiring, valve, uye zvimwe zvikamu zve exhaust gasi control system.

Zvimwe zvinokonzera

Iyi kodhi yedambudziko (P0477) inogona kuitika nekuda kweanoverengeka matambudziko anogona kuitika:

  1. Iyo exhaust manifold cheque valve ine mhosva.
  2. Wiring inobatanidza exhaust manifold check valve inogona kuvhurika kana kupfupika.
  3. Matambudziko mune exhaust manifold cheki vharafu redunhu, senge isina kusimba magetsi kubatana.
  4. Simba risina kukwana munharaunda yemagetsi pakati pekupedza gasi kudzvinyirira kutonga solenoid uye PCM (Powertrain Control Module).
  5. Vhura mumagetsi emagetsi emagetsi pakati pekupedza gasi kudzora solenoid uye PCM.
  6. Pfupi kusvika pasi mumagetsi emagetsi emagetsi eexhaust gas pressure control electromagnet.
  7. Exhaust gasi pressure control relay yakashata.
  8. Zvichida yakashata exhaust pressure control solenoid kana kunyange yakashata PCM (kunyangwe izvi zvisingaite).

Kuti ugadzirise iyi kodhi yekukanganisa, kuongororwa kunofanirwa kuitwa, kutanga nekutarisa waya nekubatanidza magetsi, uye kuenderera nekutarisa exhaust gas control system senge exhaust manifold check valve, solenoids, uye relays. Chikonzero chinonyanya kukonzera kukanganisa mu wiring kana zvikamu zvemagetsi zvegadziriro.

Ndezvipi zviratidzo zvekodhi yemhosva? P0477?

Zviratidzo zvakabatana neP0477 kodhi zvinogona kusanganisira:

  1. Iyo Malfunction Indicator Chiedza (MIL) kana "Check Injini" mwenje inouya.
  2. Kushaikwa kweinjini simba rinodiwa.
  3. Kurasikirwa kwekuita kweinjini, kusanganisira matambudziko anogona kuitika.
  4. Kuwedzera kupisa-up nguva yeinjini inotonhora.

Izvi zviratidzo zvinogona kuratidza kuderera kudzvinyirira matambudziko mune exhaust pressure control system.

Nzira yekuongorora kodhi yemhosva P0477?

Kurwisa kukanganisa kodhi P0477, zvinokurudzirwa kutevedzera aya matanho:

  1. Tarisa uye gadzirisa yakavharika kumashure pressure pipe.
  2. Gadzirisa, chenesa kana kutsiva iyo exhaust backpressure sensor.
  3. Gadzirisa kana kutsiva exhaust gasi pressure check valve.
  4. Tarisa uye, kana zvichidikanwa, gadzirisa chero yakapfupikiswa kana yakadimburwa exhaust pressure valve wiring harness.
  5. Tarisa kubatanidzwa kwemagetsi mumashure ekudzvinyirira valve circuit. Gadzirisa kana kutsiva kana zvichidikanwa.
  6. Tsiva yakamonyoroka exhaust back pressure valve solenoids.
  7. Gadzirisa kana kutsiva zvinhu zvemagetsi zvakakanganisika zvakaita sewaya nemajoi.
  8. Kana mamwe nhanho ese akatadza, funga kuvakazve iyo yakashata PCM (injini yekudzora module), kunyangwe izvi zvisingaite.
  9. Izvo zvakakoshawo kuongorora uye kugadzirisa matambudziko ane chekuita nemamwe makodhi makodhi muPCM ayo angave ane chekuita neiyo exhaust back pressure system.
  10. Usati waita nhanho idzi, zvinokurudzirwa kuti uongorore iyo Technical Service Bulletin (TSB) yemotokari yako chaiyo kuti uone kuti mugadziri wemotokari haana kupa PCM firmware kana reprogramming kugadzirisa nyaya iyi.
  11. Rangarira kuita bvunzo uchishandisa scanner chishandiso kujekesa DTCs kubva mundangariro uye ona kana iyo P0477 kodhi inodzoka mushure mekugadzirisa kwaitwa.

Zvikanganiso zvekuongorora

Kushaikwa Kuongororwa kweYakavharika Kumashure Kudzvinyirira Tube: Iyo yakavharika kana yakavharika kumashure yekumanikidza chubhu inogona kuve yakajairika chikonzero cheP0477 kodhi, zvisinei, dzimwe nguva inogona kupotsa panguva yekutanga kuongororwa. Izvo zvinodikanwa kuti uteerere kune ichi chimiro uye kutarisa mamiriro echubhu panguva yekutanga kuongororwa kwehurongwa.

Kodhi yemhosva yakakomba zvakadii? P0477?

Dambudziko rekodhi P0477, rinosanganiswa neakaderera exhaust pressure valve regulation, inogona kukanganisa injini kushanda uye kushanda zvakanaka, kunyanya panguva yekutonhora kunotanga. Nekudaro, uku hakusi kukanganisa kwakanyanya kunomisa injini nekukurumidza kana kuisa njodzi kumutyairi. Nekudaro, kana iyo P0477 kodhi ikaramba iripo, zvinogona kukonzera kuwedzera kushandiswa kwemafuta, kuderedzwa kwesimba, uye nguva yakareba yekudziya injini. Zvinokurudzirwa kugadzirisa dambudziko iri nekukurumidza sezvinobvira kudzivirira mamwe matambudziko uye kuchengetedza injini inoshanda zvakajairika.

Chii kugadzirisa kuchabatsira kubvisa kodhi? P0477?

Kugadzirisa iyo P0477 Exhaust Pressure Valve Regulation Yakaderera kodhi, ita zvinotevera kugadzirisa:

  1. Kugadzirisa uye Kugadzirisa Yakavharika Yekumashure Pressure Tube: Tarisa uone zvivharo mupombi yekupedza.
  2. Kugadzirisa, kuchenesa uye kutsiva kweiyo exhaust backpressure sensor: Iyo EBP sensor inogona kuda kucheneswa kana kutsiviwa.
  3. Kutsiva exhaust gasi pressure check valve: Kana vharuvhu yakakuvadzwa kana kusashanda nemazvo, ingada kutsiviwa.
  4. Kugadzirisa yakapfupika kana yakabviswa exhaust pressure valve harness: Tarisa mamiriro ewaya uye kugadzirisa kana kutsiva iwo kana zvichidikanwa.
  5. Kutarisa kubatanidzwa kwemagetsi mune exhaust back pressure valve circuit: Ngwarira kune mamiriro ekubatanidza magetsi uye kugadzirisa kana kutsiva kana zvichidikanwa.
  6. Kutsiva yakaremara exhaust kumashure kumanikidza vharafu solenoids: Kana iyo solenoids yakakuvadzwa, shandura iyo.
  7. Kugadzirisa kana kugadzirisa zvinhu zvakakanganisika zvemagetsi zvakaita sewaya nemajoi: Tarisa wiring yekukuvara uye kugadzirisa kana kutsiva zvinhu zvakakanganisika.
  8. Kudzorera PCM yakashata: Muzviitiko zvisingawanzo, iyo injini yekudzora module (PCM) ingangoda kugadziriswa kana kutsiviwa.
  9. Kuongorora uye kugadzirisa matambudziko ane chekuita nemamwe makodhi muPCM ane chekuita neiyo exhaust kudzoka kumanikidza system: Tarisa mamwe macode ane hukama uye gadzirisa matambudziko kana aripo.

Iva nechokwadi chekuita diagnostics uye kugadzirisa zvinoenderana nezvinokurudzirwa nemugadziri wemotokari uye shandisa iyo chaiyo michina. Zvinokurudzirwa zvakare kuti ubate ane hunyanzvi mechanic kana auto repair shop kuti uongorore uye ugadzirise P0477 kodhi dambudziko.
