P0478 Exhaust gasi pressure control valve signal yakakwira

26.05.2022 /

P0478 - OBD-II Dambudziko Code Unyanzvi Tsananguro

Dambudziko rekodhi P0478 rinoratidza kuti PCM yakaona yakakwira yakakwira voltage mumhepo yekupisa gasi rekudzora vharuvhu redunhu.

Ko fault code inorevei P0478?

Dambudziko rekodhi P0478 rinoratidza kuti injini yekudzora module (PCM) yaona yakawandisa voltage mu exhaust gas pressure valve control circuit. Iyo PCM inosarudza inodiwa yekupedza gasi kudzvanywa zvichibva pane data yakagamuchirwa kubva kune akasiyana masensa muchimiro chekuverenga voltage. Inobva yaenzanisa izvi zvakakosha nezvinodiwa nemugadziri. Kana iyo PCM ikaona yakawandisa voltage mumhepo yekupedza gasi yekudzora valve yedunhu, ichaita kuti iyo P0478 fault code ioneke. Kodhi yekukanganisa inowanzoonekwa pamwe nekodhi iyi. P0479, iyo inoratidza kusavimbika kusangana kwevhavha yemagetsi.

Mhosva kodhi P0478.

Zvimwe zvinokonzera

Zvimwe zvikonzero zvinogoneka zveP0478 dambudziko kodhi:

  • Kutadza kubuda kwegasi pressure control valve: Matambudziko nevhavha pachayo anogona kuita kuti mhepo iri mumagetsi ayo ive yakawandisa.
  • Matambudziko emagetsi: Inovhura, corrosion, kana kukuvadzwa munharaunda yemagetsi inobatanidza vharuvhu kune injini yekudzora module (PCM) inogona kukonzera yakawandisa voltage kuitika.
  • Kugadziriswa kwevharuvhu isiriyo kana kuiswa: Kugadziriswa kwevharuvhu kusina kunaka kana kuiswa kunogona kuita kuti valve iite zvisina kunaka uye inokonzera kuwandisa kwemagetsi emagetsi.
  • Matambudziko nePCM: Kashoma, kusashanda injini yekudzora module (PCM) inogonawo kukonzera yakawandisa voltage mumhepo inopedza gasi inomanikidza control valve reketi.

Ndezvipi zviratidzo zvekodhi yemhosva? P0478?

Zviratidzo zveDTC P0478 zvinogona kusanganisira zvinotevera:

  • Tarisa Engine light on: Kana dambudziko rekodhi P0478 raonekwa, iyo Cheka Injini Mwenje kana MIL (Malfunction Indicator Lamp) inogona kuuya pane chako chiridzwa.
  • Kurasikirwa kwesimba reinjini: Kana iyo yekupedza gasi yekumanikidza control valve isingashande nemazvo nekuda kweiyo yakakwira voltage, inogona kukonzera kurasikirwa kweinjini simba.
  • rough or rough idle: High voltage muvhavhavha yedunhu inogona kuita kuti chisimbe chive chisina kugadzikana kana chakashata.
  • Matambudziko nehupfumi hwemafuta: Matambudziko ane chekuita nekupedza gasi kumanikidza anogona zvakare kukanganisa hupfumi hwemafuta, zvichikonzera kuwedzera kwemafuta.
  • Unstable engine performance: Kana mhepo iri muvhavhavhavha yakanyanyisa, injini inogona kushanda yakaoma kana kusashanda.

Nzira yekuongorora kodhi yemhosva P0478?

Kuti uongorore DTC P0478, matanho anotevera anokurudzirwa:

  1. Tarisa Cheki Engine Chiedza: Tarisa kuti uone kana mwenje weCheck Engine pane mudziyo wemidziyo unouya. Kana hongu, batanidza mota kune diagnostic scan tool kuti uwane chaiyo yekukanganisa macode.
  2. Shandisa diagnostic scanner: Batanidza diagnostic scanner kune yemotokari OBD-II port uye uverenge makodhi ekukanganisa. Nyora pasi makodhi ane hukama nepamusoro voltage mune exhaust gas pressure control valve circuit.
  3. Tarisa kutenderera kwemagetsi: Tarisa kupera kwegasi kudzvinyirira kudzora vharafu yemagetsi emagetsi ekuora, kutyora kana kukuvara. Ita shuwa kuti zvese zvinongedzo zvakachengeteka uye zvinobatika zvakachena.
  4. Tarisa pressure control valve: Tarisa kuburitsa gasi kudzvinyirira kudzora vharafu pachayo kukuvadza kana kusashanda. Ita shuwa kuti inovhura uye inovhara nemazvo.
  5. Tarisa masensa uye waya: Chengetedza mamiriro emagetsi ose akabatanidzwa nevhavha yekudzivirira, pamwe chete netambo dzemagetsi, uye ona kuti dzakabatana uye dzinoshanda zvakanaka.

Zvichienderana nemhedzisiro yekuongorora, ita kugadzirisa kunodiwa, kutsiva zvakakanganisika, kana sevhisi dunhu remagetsi.

Zvikanganiso zvekuongorora

Kana uchiongorora DTC P0478, zvikanganiso zvinotevera zvinogona kuitika:

  • Kuverenga kodhi isiriyo: Kutadza kuverenga kodhi yekukanganisa zvakanaka kana kuidudzira zvisizvo kunogona kuita kuti dambudziko risaonekwa.
  • Matambudziko emagetsi: Kukanganisa kwemagetsi sekuvhura, shorts kana kukuvadzwa wiring kunogona kutungamirira pakududzira zvisizvo kana kusaziva.
  • Sensor kana vharafu kusashanda zvakanaka: Kana iyo inopera gasi inodzvinyirira inodzora valve pachayo kana iyo sensor inokanganisa, inogona kutungamirira kune zvisiri izvo kuongororwa kwechikonzero chekukanganisa.
  • Software matambudziko: Dzimwe nguva matambudziko nesoftware yemotokari kana module yayo yekudzora inogona kukonzera kusaziva.
  • Kusashanda kwezvimwe zvikamu: Zvimwe zvikanganiso zvine mamwe maitiro kana injini zvikamu zvinogona kuratidza seP0478 kodhi, saka zvakakosha kutarisa zvese zvine hukama masisitimu uye zvikamu usati waita sarudzo yekupedzisira.

Kuti udzivise zvikanganiso izvi, zvakakosha kuita zvakarongeka uye nekuchenjerera kuongororwa uye kuvimba nenzira dzakaratidzwa uye zvishandiso.

Yakakomba sei dambudziko rekodhi P0478?

Dambudziko rekodhi P0478 rinogona kunge rakakomba nekuti rinoratidza matambudziko anogona kuitika neiyo exhaust gas pressure control valve kana dunhu remagetsi. Kana vharuvhu isingashande nemazvo, inogona kuguma nekuwedzera kuomeswa kwemhepo mukati meiyo exhaust system, izvo zvinogona kukonzera zvisingadiwe mhedzisiro senge kusashanda kweinjini, kuwedzera kubuda, uye kuderedzwa kweinjini hupfumi uye kuita. Naizvozvo, zvakakosha kutora kodhi yeP0478 zvakakomba uye kuti iongororwe uye igadziriswe nekukurumidza kuti udzivise matambudziko angangoita injini uye exhaust system.

Chii kugadzirisa kuchabatsira kubvisa kodhi? P0478?

Aya anotevera matanho ekugadzirisa anokurudzirwa kugadzirisa iyo P0478 kodhi:

  1. Kuongorora kwemagetsi: Tarisa kutenderera kwemagetsi kunobatanidza exhaust gas pressure control valve kune injini control module (PCM). Ita shuwa kuti waya hadzina kuputsika kana kukuvara uye dzakabatana nemazvo.
  2. Kuongorora exhaust gasi pressure control valve: Tarisa vharafu pachayo kuti ikuvadze, kuparara kana mamwe matambudziko anogona kuita kuti isashande. Dzorera valve kana zvichidiwa.
  3. Kutarisa masensa uye kupera simba gasi: Tarisa ma sensors uye mamwe exhaust pressure ane chekuita nesystem zvikamu kuti ave nechokwadi chekuti ari kushanda nemazvo.
  4. Tarisa PCM: Muzviitiko zvisingawanzoitiki, dambudziko rinogona kunge riri nekuda kwedambudziko nejini yekudzora module (PCM) pachayo. Tarisa iyo PCM yekutadza kana kutadza uye woitsiva kana zvichidikanwa.
  5. Kubvisa zvikanganiso uye kuongorora zvakare: Mushure mekupedza kugadzirisa kwese kunodiwa, bvisa makodhi ezvikanganiso uchishandisa diagnostic scan tool uye tarisa zvakare hurongwa kuti uone kuti dambudziko ragadziriswa zvinobudirira.

Kana usina chokwadi chehunyanzvi hwako hwekugadzirisa mota kana ruzivo, zvinokurudzirwa kuti ubate makanika ane hunyanzvi kana chitoro chekugadzirisa mota kuti uongorore uye kugadzirisa dambudziko.
