P0477 - OBD-II Mavuto Code Kufotokozera

Vavu yotulutsa mpweya wotulutsa mpweya "A" yotsika

Kodi cholakwika chimatanthauza chiyani P0477?

Vuto la P0477 limagwirizana ndi kutsika kwa valve yamagetsi ndipo imatha kuchitika pamagalimoto osiyanasiyana, kuphatikiza Ford, Dodge, Mercedes, Nissan ndi VW. Khodi iyi ikuwonetsa voteji yolakwika yomwe ikuwerengedwa ndi sensa yotulutsa mpweya ndikutumizidwa ku gawo lowongolera injini (PCM). Ngati mphamvuyi ili pansi pa nthawi zonse, PCM imasunga code P0477.

The exhaust backpressure valve imayang'anira kutuluka kwa mpweya, zomwe zimathandiza kuonjezera kutentha kwa mkati ndi kuchepetsa nthawi ya windshield defrost mu kutentha kochepa kozungulira. Engine Control Module (ECM) imagwiritsa ntchito zidziwitso zakumbuyo kwa mpweya, kutentha kwa mpweya, kutentha kwamafuta a injini, ndi kuchuluka kwa injini kuwongolera valavu. Valavu imayendetsedwa kudzera pa 12V yotulutsa dera mkati mwa ECM.

M'malo otsika ozungulira komanso zinthu zina, valavu ikhoza kukhala yotsekedwa pang'ono, zomwe zimapangitsa kuti mkatimo kutentha. Pamene injini ndi mafuta zikuwotcha, valavu imayang'anira kuthamanga kwa mpweya. Kuthetsa mavuto P0477 kungafunike kuyang'ana mawaya, valavu, ndi zigawo zina za dongosolo la mpweya wotulutsa mpweya.

Zotheka

Khodi yamavuto iyi (P0477) imatha kuchitika chifukwa cha zovuta zingapo:

  1. Valovu yoyendera manifold exhaust ndiyolakwika.
  2. Mawaya olumikiza valavu yamagetsi otulutsa amatha kukhala otseguka kapena ofupikitsidwa.
  3. Mavuto mu utsi wochuluka cheke valavu dera, monga kulephera kugwirizana magetsi.
  4. Mphamvu zosakwanira mumayendedwe amagetsi pakati pa solenoid yotulutsa mpweya wotulutsa mpweya ndi PCM (Powertrain Control Module).
  5. Tsegulani mu dera loperekera mphamvu pakati pa mpweya wotulutsa mpweya wa solenoid ndi PCM.
  6. Chachifupi mpaka pansi mu gawo lamagetsi lamagetsi amagetsi otulutsa mpweya wamagetsi.
  7. Kuthamangitsidwa kwa gasi wotulutsa mpweya ndikolakwika.
  8. Vuto lomwe lingakhalepo ndi mpweya wotulutsa mpweya wotulutsa solenoid kapena vuto ndi PCM (ngakhale izi sizingatheke).

Kuti athetse vutoli, kuwunika kuyenera kuchitidwa, kuyambira ndikuyang'ana mawaya ndi kulumikizana kwamagetsi, ndikupitiliza kuyang'ana zida zowongolera mpweya wamagetsi monga valavu yotulutsa manifold manifold check valve, solenoids, ndi ma relay. Chomwe chingakhale chotheka kwambiri ndi vuto la mawaya kapena magawo amagetsi a dongosolo.

Kodi zizindikiro za cholakwika ndi chiyani? P0477?

Zizindikiro zolumikizidwa ndi nambala ya P0477 zitha kuphatikiza:

  1. Kuwala kwa Malfunction Indicator Light (MIL) kapena "Check Engine" kumabwera.
  2. Kusowa mphamvu zofunika injini.
  3. Kuwonongeka kwa magwiridwe antchito a injini, kuphatikiza zovuta zomwe zingachitike pamakokedwe.
  4. Kuwotcha nthawi yowonjezera injini yozizira.

Zizindikirozi zikhoza kusonyeza mavuto otsika kwambiri mu dongosolo la kutulutsa mphamvu.

Momwe mungadziwire cholakwika P0477?

Kuti muthane ndi cholakwika cholakwika P0477, tikulimbikitsidwa kutsatira izi:

  1. Yang'anani ndikukonza chitoliro chotsekeka kumbuyo.
  2. Konzani, yeretsani kapena sinthani sensa ya exhaust backpressure.
  3. Konzani kapena sinthani valavu yowunikira mpweya wotulutsa mpweya.
  4. Yang'anani ndipo, ngati n'koyenera, konzani chingwe chilichonse chofupikitsa kapena chosalumikizidwa.
  5. Yang'anani kugwirizana kwa magetsi mu dera lakumbuyo la valve. Konzani kapena kusintha ngati kuli kofunikira.
  6. M'malo mokhotakhota utsi wokhotakhota kumbuyo kuthamanga valavu solenoids.
  7. Konzani kapena kusintha zida zowonongeka monga mawaya ndi zolumikizira.
  8. Ngati masitepe ena onse alephera, lingalirani zomanganso PCM yolakwika (module yowongolera injini), ngakhale izi sizingatheke.
  9. Ndikoyeneranso kuzindikira ndi kukonza mavuto okhudzana ndi ma code ena olakwika mu PCM omwe angagwirizane ndi dongosolo lotopetsa lakumbuyo.
  10. Musanachite izi, ndi bwino kuti muyang'anenso Technical Service Bulletin (TSB) ya galimoto yanu kuti muwonetsetse kuti wopanga galimotoyo sanapereke firmware ya PCM kapena reprogramming kuti athetse vutoli.
  11. Kumbukirani kuyesa pogwiritsa ntchito chida chojambulira kuti muchotse ma DTC pamtima ndikuwona ngati nambala ya P0477 ibwerera pambuyo pokonzanso.

Zolakwa za matenda

Kusowa Kuzindikira kwa Chubu Chotsekeka Chakumbuyo Chotsekeka: Chubu chotsekeka kapena chotsekeka chakumbuyo chingakhale chifukwa chofala cha nambala ya P0477, komabe, nthawi zina imatha kuphonya pakuzindikira koyamba. M'pofunika kulabadira mbali imeneyi ndi kuona mmene chubu pa koyamba anayendera dongosolo.

Kodi zolakwika ndizovuta bwanji? P0477?

Khodi yamavuto P0477, yolumikizidwa ndi kutsika kwa valve yamagetsi, imatha kusokoneza magwiridwe antchito a injini, makamaka pakuzizira kozizira. Komabe, uku si vuto lalikulu lomwe lingayimitse injini nthawi yomweyo kapena kuyika ngozi kwa dalaivala. Komabe, nambala ya P0477 ikapitilira, zitha kupangitsa kuti mafuta achuluke, kuchepetsa mphamvu, komanso nthawi yayitali yotenthetsera injini. Ndibwino kuti tithetse vutoli mwamsanga kuti tipewe mavuto ena ndikusunga injini ikuyenda bwino.

Kodi kukonza kungathandize kuthetsa code? P0477?

Kuti muthetse P0477 Exhaust Pressure Valve Regulation Low code, konzekerani izi:

  1. Kukonza ndi Kukonza Chubu Chotsekeka Chakumbuyo: Yang'anani zotsekeka mu chitoliro cha utsi.
  2. Kukonza, kuyeretsa ndikusinthanso sensor ya exhaust backpressure: Sensa ya EBP ingafune kuyeretsedwa kapena kusinthidwa.
  3. Kusintha valve yotulutsa mpweya wotulutsa mpweya: Ngati valavu yawonongeka kapena yosagwira ntchito bwino, ingafunike kusinthidwa.
  4. Kukonza valavu yafupika kapena yosalumikizidwa: Yang'anani momwe mawaya alili ndikukonza kapena kuwasintha ngati kuli kofunikira.
  5. Kuyang'ana kulumikizidwa kwamagetsi mu exhaust back pressure valve circuit: Samalani ndi momwe magetsi amalumikizidwira ndikukonza kapena kusintha ngati kuli kofunikira.
  6. Kusintha ma valve opunduka a valve solenoids: Ngati solenoids awonongeka, m'malo mwake.
  7. Kukonza kapena kusintha zida zowonongeka zamagetsi monga mawaya ndi zolumikizira: Yang'anani mawaya kuti awonongeke ndikukonza kapena kusintha zida zowonongeka.
  8. Kubwezeretsa PCM yolakwika: Nthawi zina, gawo lowongolera injini (PCM) lingafunike kukonzedwa kapena kusinthidwa.
  9. Kuzindikira ndi kuthetsa mavuto okhudzana ndi ma code ena mu PCM okhudzana ndi dongosolo la kuthamangitsidwa kwa exhaust return: Yang'anani ma code ena okhudzana ndi kuthetsa mavuto ngati alipo.

Onetsetsani kuti mukuchita diagnostics ndi kukonza molingana ndi malangizo a wopanga galimoto ndikugwiritsa ntchito zida zolondola. Ndikulimbikitsidwanso kuti mulumikizane ndi makanika oyenerera kapena malo okonzera magalimoto kuti muzindikire molondola ndikuthetsa vuto la code P0477.
