P0478 - OBD-II Mavuto Code Kufotokozera
Khodi yamavuto P0478 ikuwonetsa kuti PCM yapeza voteji yokwera kwambiri pamagetsi otulutsa mpweya wotulutsa mpweya.
Kodi cholakwika chimatanthauza chiyani P0478?
Khodi yamavuto P0478 ikuwonetsa kuti gawo lowongolera injini (PCM) lapeza voteji yokwera kwambiri pamagetsi otulutsa mpweya wotulutsa mpweya. PCM imatsimikizira kuthamanga kwa gasi wotopetsa kutengera zomwe zalandilidwa kuchokera ku masensa osiyanasiyana monga kuwerengera kwamagetsi. Kenako imafanizira izi ndi zomwe wopanga amapanga. Ngati PCM iwona magetsi okwera kwambiri pamagetsi otulutsa mpweya wotulutsa mpweya, zipangitsa kuti P0478 iwonekere. Khodi yolakwika nthawi zambiri imapezeka pamodzi ndi code iyi. P0479, zomwe zimasonyeza kukhudzana kosadalirika kwa dera lamagetsi la valve.
Zotheka
Zina mwazifukwa za vuto la P0478:
- Valavu yowongolera mphamvu ya gasi yolakwika: Mavuto ndi valavu palokha angayambitse voteji mu dera lake lamagetsi kukhala okwera kwambiri.
- Mavuto amagetsi: Kutsegula, corrosion, kapena kuwonongeka kwa dera lamagetsi kulumikiza valavu ku injini yoyendetsera injini (PCM) kungayambitse magetsi ochulukirapo.
- Kuyika kapena kuyika ma valve olakwika: Kuwongolera kolakwika kwa ma valve kapena kuyika kungapangitse kuti valavu igwire ntchito molakwika ndipo imapangitsa kuti magetsi aziyenda kwambiri.
- Mavuto ndi PCM: Kawirikawiri, injini yoyendetsa injini yosagwira ntchito (PCM) ingayambitsenso magetsi ochulukirapo pamagetsi otulutsa mpweya wothamanga.
Kodi zizindikiro za cholakwika ndi chiyani? P0478?
Zizindikiro za DTC P0478 zingaphatikizepo izi:
- Yang'anani kuwala kwa injini: Pomwe vuto la P0478 likuwonekera, Kuwala kwa Injini Yoyang'ana kapena MIL (Lamp Indicator Lamp) ikhoza kubwera pazida zanu.
- Kutaya mphamvu ya injini: Ngati mpweya wotulutsa mpweya wotulutsa mpweya sugwira ntchito bwino chifukwa cha mphamvu yamagetsi, ukhoza kuwononga mphamvu ya injini.
- Zovuta kapena zopanda pake: Kuchuluka kwamagetsi mumagetsi a valve kungayambitse kusakhazikika kapena kovuta.
- Mavuto ndi kuchepa kwamafuta: Mavuto okhudzana ndi kuthamanga kwa gasi amathanso kuwononga mafuta, zomwe zimapangitsa kuti mafuta achuluke.
- Magwiridwe a injini osakhazikika: Ngati voteji mu dera la valavu ndipamwamba kwambiri, injini ikhoza kukhala yovuta kapena yosagwira ntchito.
Momwe mungadziwire cholakwika P0478?
Kuti muzindikire DTC P0478, njira zotsatirazi zikulimbikitsidwa:
- Onani Kuwala kwa Injini Yoyang'ana: Yang'anani kuti muwone ngati kuwala kwa Injini Yoyang'ana pagawo la chida kumabwera. Ngati inde, lumikizani galimotoyo ku chida chowunikira kuti mupeze zolakwika zinazake.
- Gwiritsani ntchito scanner yowunika: Lumikizani chojambulira chowunikira ku doko la OBD-II lagalimoto ndikuwerenga zolakwika. Lembani ma code okhudzana ndi voteji yayikulu mu gawo la exhaust gas pressure control valve circuit.
- Yang'anani dera lamagetsi: Yang'anani valavu yamagetsi yamagetsi yotulutsa mpweya kuti iwononge, kusweka kapena kuwonongeka. Onetsetsani kuti zolumikizira zonse ndi zotetezeka komanso zolumikizirana ndi zoyera.
- Onani valavu yowongolera kuthamanga: Yang'anani valavu yowongolera mpweya wotulutsa mpweya wokha kuti uwonongeke kapena kusagwira ntchito. Onetsetsani kuti ikutsegula ndi kutseka bwino.
- Onani masensa ndi mawaya: Yang'anani mkhalidwe wa masensa onse okhudzana ndi valve control valve, komanso mawaya amagetsi, ndipo onetsetsani kuti akugwirizana ndikugwira ntchito moyenera.
Malingana ndi zotsatira za matenda, pangani kukonzanso koyenera, m'malo mwa zigawo zowonongeka, kapena gwiritsani ntchito dera lamagetsi.
Zolakwa za matenda
Mukazindikira DTC P0478, zolakwika zotsatirazi zitha kuchitika:
- Kuwerenga kolakwika: Kulephera kuwerenga zolakwika kapena kutanthauzira molakwika kungapangitse kuti vutoli lisazindikiridwe.
- Mavuto amagetsi: Zowonongeka zamagetsi monga zotsegula, zazifupi kapena mawaya owonongeka angayambitse kutanthauzira molakwika kapena kusazindikira.
- Sensor kapena valve kulephera kugwira ntchito: Ngati mpweya wotulutsa mpweya wotulutsa mpweya wokhawokha kapena sensa ili yolakwika, ingayambitse matenda olakwika a chifukwa cha cholakwikacho.
- Mavuto a mapulogalamu: Nthawi zina zovuta ndi pulogalamu yagalimoto kapena gawo lowongolera zimatha kuyambitsa kuzindikirika molakwika.
- Kuwonongeka kwa zigawo zina: Zolakwa zina ndi machitidwe ena kapena zida za injini zingasonyeze ngati P0478 code, choncho ndikofunika kufufuza machitidwe onse okhudzana ndi zigawozo musanapange chitsimikiziro chomaliza.
Kuti mupewe zolakwika izi, ndikofunikira kuti muzindikire mwadongosolo komanso mosamala ndikudalira njira ndi zida zotsimikiziridwa.
Kodi vuto la P0478 ndi lalikulu bwanji?
Khodi yamavuto P0478 ikhoza kukhala yayikulu chifukwa imawonetsa zovuta zomwe zingachitike ndi valavu yowongolera mpweya wamagetsi kapena magetsi ake. Ngati valavu sikugwira ntchito bwino, ingayambitse kuwonjezereka kwa mpweya wotulutsa mpweya, zomwe zingayambitse zotsatira zosafunikira monga kusagwira bwino ntchito kwa injini, kuwonjezereka kwa mpweya, ndi kuchepetsa chuma cha injini ndi ntchito. Chifukwa chake, ndikofunikira kuti mutenge kachidindo ka P0478 mozama ndikuzindikiritsa ndikukonzanso posachedwa kuti mupewe zovuta zomwe zingachitike ndi injini ndi utsi.
Kodi kukonza kungathandize kuthetsa code? P0478?
Njira zokonzetsera zotsatirazi ndizolimbikitsa kuthetsa nambala ya P0478:
- Kuwunika kwamagetsi: Yang'anani dera lamagetsi lomwe limagwirizanitsa valavu yotulutsa mpweya wamagetsi ku injini yoyendetsera injini (PCM). Onetsetsani kuti mawaya sanathyoke kapena kuwonongeka ndipo alumikizidwa bwino.
- Kuyang'ana valavu yoyendetsera gasi yotulutsa mpweya: Yang'anani valavu yokha kuti iwonongeke, yawonongeka kapena mavuto ena omwe angapangitse kuti isagwire bwino. Bwezerani valavu ngati kuli kofunikira.
- Kuyang'ana masensa ndi mpweya wotulutsa mpweya: Onani masensa ndi zida zina zamakina okhudzana ndi kutopa kuti muwonetsetse kuti zikuyenda bwino.
- Onani PCM: Nthawi zina, vuto likhoza kukhala chifukwa cha vuto ndi gawo lowongolera injini (PCM) lokha. Yang'anani PCM kuti muwone zolephera kapena zolephera ndikuzisintha ngati kuli kofunikira.
- Kuchotsa zolakwika ndikuwunikanso: Mukamaliza kukonza zonse zofunika, chotsani zolakwikazo pogwiritsa ntchito chida chowunikira ndikuwunikanso dongosolo kuti muwonetsetse kuti vutoli lathetsedwa bwino.
Ngati simukutsimikiza za luso lanu lokonza magalimoto kapena luso lanu, tikulimbikitsidwa kuti mulumikizane ndi makanika oyenerera kapena malo okonzera magalimoto kuti muzindikire ndikukonza vutolo.
P0478 - Zambiri zokhudzana ndi mtundu
Khodi yamavuto P0478 imatanthawuza kuwongolera injini yamagetsi ndipo imapezeka pamitundu yosiyanasiyana yamagalimoto, mndandanda wazinthu zina ndi matanthauzo ake:
- Ford: Vavu yowongolera mpweya wotulutsa mpweya - voteji yayikulu.
- Chevrolet / GMC: Kutulutsa mpweya wamagetsi owongolera ma valve ndi apamwamba.
- Dodge / Ram: Vavu yowongolera mpweya wotulutsa mpweya - voteji yayikulu.
