P0470 - OBD-II Dambudziko Code Unyanzvi Tsananguro

Pedza gasi kumanikidza sensor kusashanda

Ko fault code inorevei P0470?

Iyi general diagnostic problem code inoshanda kune dzakasiyana siyana kugadzirwa kwemotokari, kusanganisira Ford, Mercedes neNissan, ine mhando dzakasiyana dzeinjini, kusanganisira peturu nedhiziri, kutanga muna 2005. Iyo ine hukama nekupedza gasi kudzvanywa uye inogona kuratidza dambudziko remagetsi kana mechanical. Iyo dzimwe nguva inogona kuperekedzwa neP0471 kodhi, iyo inosiyana muhurefu uye hunhu hwekuneta kwekumanikidza sensor kutadza. Matanho ekugadzirisa anoenderana nemugadziri, rudzi rwemafuta uye ruvara rwewaya.

Dambudziko kodhi P0470 yakajairika kune akasiyana magadzirirwo uye mhando dzemota. Inoratidza dambudziko nekupedza gasi pressure sensor uye inogona kunge iri nekuda kwemagetsi kana mechanical matambudziko. Dzimwe nguva inoperekedzwa neP0471 kodhi, iyo inosiyana munguva yedambudziko uye chimiro chekutadza kwe sensor. Matanho ekugadzirisa anogona kusiyana zvichienderana nemugadziri, rudzi rwemafuta, uye ruvara rwewaya.

Iyo Exhaust Back Pressure (EBP) sensor inoita basa rakakosha pakuyera kupera simba gasi uye inobvumira kutonga kweExhaust Back Pressure Regulator (EPR) nekuraira kubva kuInjini Kudzora Module (ECM).

Chaizvoizvo Exhaust Pressure Gauge:

Yakakodzera Exhaust Pressure Sensor Dambudziko Makodhi:

  • P0471 Exhaust Gasi Pressure Sensor "A" Circuit Range/Kuita
  • P0472 Yakaderera siginecha nhanho mune exhaust gasi kumanikidza sensor redunhu "A"
  • P0473 Exhaust gasi pressure sensor "A" dunhu rakakwirira
  • P0474 Exhaust gasi pressure sensor "A" kusashanda kwedunhu

Zvimwe zvinokonzera

Iyi P0470 kodhi inogona kuoneka nekuda kwezvikonzero zvinotevera:

  1. Pane kuvharika muchubhu pakati pe exhaust manifold uye pressure sensor.
  2. Matambudziko neEGR kana air intake system, kusanganisira yekuchaja mhepo inodonha.
  3. Yakaremara exhaust gasi pressure sensor.
  4. Kashoma: Kunogona kukanganisa kuPowertrain Control Module (PCM), kunyangwe zvisingaite.
  5. Iko kune kuvharika mupombi inobatanidza iyo yekumanikidza sensor kune exhaust manifold.
  6. Iyo exhaust gasi recirculation system iri kutadza kushanda, izvo zvinogona kutungamirira kune kubuda kwemhepo.
  7. Yakashata exhaust backpressure sensor.
  8. Matambudziko ane exhaust backpressure sensor wiring harness, sekuvhura kana mapfupi maseketi.
  9. Kubatana kwemagetsi kwakashata mune exhaust backpressure sensor circuit.

Ndezvipi zviratidzo zvekodhi yemhosva? P0470?

Zviratidzo zveP0470 kodhi zvinosanganisira:

  1. Iyo Malfunction Indicator Chiedza (MIL), inozivikanwawo secheki injini mwenje, inouya.
  2. Zvinogoneka kutaridzika kwe "Check Injini" mwenje pane control panel ine kukanganisa kodhi yakachengetwa muECM ndangariro.
  3. Kurasikirwa kweinjini simba.
  4. Kugona kudzima exhaust gasi pressure regulator.

Iyo P0470 kodhi inoonekwa yakakomba nekuti inogona kukanganisa mabatiro nekuita kwemotokari. Asi inogona kupedzwa nyore nyore nekutsiva iyo yakaremara exhaust gasi pressure sensor.

Zviratidzo zveP0470 kodhi zvinogona zvakare kusanganisira:

  1. Cheki injini chiedza chinogara chakabatidzwa.
  2. Kushaya simba.
  3. Kutadza kudzoreredza dhiziri particulate sefa, izvo zvinogona kuita kuti injini itange kutadza.

Nzira yekuongorora kodhi yemhosva P0470?

Nzira yakanaka yekutanga kuongorora P0470 kodhi ndeyekutarisa iyo Technical Service Bulletin (TSB) yekugadzira kwako mota. Mugadziri anogona kupa software yekuvandudza (firmware) yePCM kugadzirisa dambudziko iri. Tevere, tsvaga yekubuda gasi kumanikidza sensor pamotokari yako uye bvisa chubhu inoibatanidza kune yakawanda yekuburitsa.

Edza kubvisa iyi chubhu chero kabhoni inogona kunge iri kukonzera iyo P0470 kodhi. Kana iyo chubhu yakachena, tarisa majoini uye wiring kukuvara kana ngura. Tevere, edza iyo 5V simba uye sensor masaini maseketi uchishandisa dijitari volt-ohmmeter (DVOM).

Ita shuwa kuti sensor yakadzikwa zvakanaka. Kana bvunzo dzese dzikapfuura, kutsiva kweiyo exhaust gasi pressure sensor inogona kudikanwa. Kana iyo P0470 kodhi ikaramba ichionekwa, PCM ine mhosva inogonawo kunge iri chikonzero, asi inogona kubviswa kunze mushure mekutsiva sensor uye kuita mimwe miedzo.

Zvikanganiso zvekuongorora

Zvinogona zvikonzero zveP0470 kodhi

Paunenge uchiongorora kodhi yeP0470, zvakakosha kuti utarise akati wandei zvikonzero zvinogona kutungamira kune iyi kodhi. Pazasi pane zvinhu zvikuru zvekufunga nezvazvo:

  1. Kuvharika muchubhu kubva kune exhaust manifold kune yekumanikidza sensor: Imwe inogoneka mamiriro ezvinhu ndeyekuti kabhoni inovaka mukati meiyo exhaust system, iyo inogona kukonzera kuvharika muchubhu iyo iyo yekumanikidza sensor inogamuchira ruzivo. Izvi zvinogona kuguma nekuverenga zvisirizvo uye P0470 kodhi.
  2. Matambudziko neiyo exhaust gasi recirculation (EGR) system, kupinza mhepo kana kubhadharisa kudonha kwemhepo: Matambudziko ane exhaust kana mweya wekupa masisitimu anogona kukanganisa kudzvanywa kweiyo exhaust system uye kukonzera iyo P0470 kodhi. Kuongororwa kwakavimbika kwezvikamu izvi kunogona kuva danho rinokosha.
  3. Exhaust gasi pressure sensor kusashanda zvakanaka: Iyo yekupedza gasi yekumanikidza sensor pachayo inogona kutadza kana kuburitsa zvisizvo zvikwangwani, zvichikonzera P0470 kodhi.
  4. Exhaust Back Pressure (EBP) Sensor Matambudziko: Iyo yekupedza backpressure sensor chinhu chakakosha cheiyo injini manejimendi system uye inogona kubatanidzwa neiyo P0470 kodhi.
  5. Matambudziko ne wiring nekubatanidza magetsi: Waya dzakakuvadzwa, corrosion, kana kusakodzera magetsi kubatana pakati pe sensors uye control system inogona kukonzera zviratidzo zvisirizvo uye P0470 kodhi.

Izvi zvinogona zvikonzero zveP0470 kodhi zvakakosha kufunga panguva yekuongorora uye kugadzirisa kunongedza uye kugadzirisa mudzi wedambudziko.

Kodhi yemhosva yakakomba zvakadii? P0470?

Dambudziko rekodhi P0470 rinoratidza dambudziko nekupedza gasi pressure sensor kana exhaust system pressure. Izvi zvinogona kukanganisa kushanda kweinjini, kuita uye kushandiswa kwemafuta. Kunyangwe ichi chisiri chimbichimbi chakakosha, iko kusashanda kwakakomba kunogona kutungamirira kune mamwe matambudziko akakomba kana ikasagadziriswa. Zvinokurudzirwa kuti injini yako iongororwe uye igadziriswe namakanika apo iyo P0470 kodhi inoratidzika kudzivirira kuparara kweinjini uye kuchengetedza kushanda kweinjini.

Chii kugadzirisa kuchabatsira kubvisa kodhi? P0470?

Kugadzirisa iyo P0470 kodhi kunosanganisira akati wandei matanho, zvichienderana nechikonzero chakaonekwa:

  1. Kutarisa Technical Service Bulletins (TSB): Tanga nekutsvaga ruzivo mune tekinoroji sevhisi bulletins, inogona kunge iine mazano emugadziri ekugadzirisa dambudziko iri. Mugadziri anogona kupa PCM inopenya / inotsvedza iyo inogona kujekesa kodhi.
  2. Kuongorora iyo exhaust pressure sensor: Bvisa iyo exhaust gasi pressure sensor uye tarisa kabhoni deposits kana kukuvara. Chenesa kana kutsiva sensor kana zvichidikanwa.
  3. Wiring check: Ongorora nemaziso, tarisa kukuvara, ngura kana waya dzakaputsika. Bvisa zvibatanidza uye uzvichenese kana zvichidikanwa.
  4. Kutarisa simba uye masaini maseketi: Uchishandisa dijitari volt-ohm mita (DVOM), tarisa iyo 5V simba uye masaini maseketi anoenda kune sensor. Ita shuwa kuti voltage inosangana nezvinodiwa nemugadziri.
  5. Grounding check: Tarisa uone kana iyo exhaust gasi pressure sensor yakadzikwa zvakanaka.
  6. Kutarisa chubhu uye zvinongedzo: Nyatsotarisa chubhu inobatanidza turbocharger kune yakawanda yekutora kuti ibude.
  7. Kubvisa kukanganisa: Shandisa OBD-II scanner kujekesa iyo P0470 kodhi kubva kuPCM ndangariro. Mushure meizvi, tyaira mota uye tarisa kana kukanganisa kunoonekwa zvakare.
  8. Kutsiva Sensor: Kana dambudziko risingakwanisi kugadziriswa nedzimwe nzira, shandura iyo inopera gas pressure sensor.
  9. Kuongorora kwePCM: Kana ese ari pamusoro apa akasagadzirisa dambudziko, panogona kunge paine dambudziko nePCM. Nekudaro, iyi sarudzo inofanirwa kungoonekwa seyekupedzisira sarudzo yekushandisa.

Rangarira kuti kuongororwa uye kugadzirisa kunofanirwa kuitwa nemakanika ane hunyanzvi kana nzvimbo yebasa kuti ive nechokwadi chechikonzero chaicho uye kugadzirisa kunoshanda kweiyo P0470 kodhi.
