P0479 Exhaust gas pressure control valve circuit intermittent

P0479 - OBD-II Mavuto Code Kufotokozera

Khodi yamavuto P0479 ikuwonetsa kuti PCM yazindikira mphamvu yapakati pamagetsi otulutsa mpweya wotulutsa mpweya.

Kodi cholakwika chimatanthauza chiyani P0479?

Khodi yamavuto P0479 ikuwonetsa voteji yapakatikati pamagetsi otulutsa mpweya wotulutsa mpweya. Khodi iyi nthawi zambiri imapezeka pamagalimoto okhala ndi dizilo ndi ma turbocharged omwe amawunika kuthamanga kwa gasi. M'magalimoto okhala ndi dizilo kapena ma turbocharged, valavu yamagetsi yotulutsa mpweya ndiyomwe imayang'anira kuthamangitsa kwa gasi wotulutsa. PCM imawerengera yokha mphamvu ya gasi yotulutsa mpweya wofunikira potengera zomwe zalandilidwa kuchokera ku sensa ya throttle position, tachometer ndi masensa ena monga momwe amawerengera magetsi. Ngati PCM iwona kuti mpweya wotulutsa mpweya wothamanga wa valve wozungulira ndi wapakati, P0479 idzachitika.

Zotheka

Zina mwazifukwa za vuto la P0479:

• Kusagwira ntchito bwino kwa mpweya wotulutsa mpweya wotulutsa mpweya: Vavu ikhoza kuonongeka kapena yolakwika, zomwe zimapangitsa kuti mpweya wotulutsa mpweya usasinthe bwino.
• Mavuto Ozungulira: Kutsegula, kuwononga, kapena kuwonongeka kwina mu dera lamagetsi kulumikiza valavu yotulutsa mpweya wotulutsa mpweya ku injini yoyendetsera injini (PCM) kungayambitse kuwerengedwa kolakwika kapena palibe chizindikiro kuchokera ku valve.
• Nkhani za Sensor: Kusagwira ntchito kwa throttle position sensor, tachometer, kapena masensa ena omwe PCM amagwiritsa ntchito kuti awerengetse kuthamanga kofunikira kungayambitsenso P0479.
• Mavuto a Mapulogalamu a PCM: Mapulogalamu a PCM olakwika kapena osagwira ntchito angayambitse valavu yotulutsa mpweya kuti isagwire bwino ntchito.

Kodi zizindikiro za cholakwika ndi chiyani? P0479?

Zizindikiro za DTC P0479 zitha kusiyana kutengera chomwe chimayambitsa komanso mtundu wagalimoto:

• Khodi yolakwika ya Check Engine ikuwonekera pa dashboard yagalimoto.
• Kutayika kwa mphamvu ya injini kapena ntchito yosakhazikika.
• Kuwonongeka kwamafuta amafuta.
• Mavuto ndi mathamangitsidwe kapena pang'onopang'ono kuyankha kwa gasi pedal.
• Kumveka kwachilendo kapena kugwedezeka kwa injini.
• Kuchuluka kwamafuta.
• Kununkhira kwachilendo kwa dongosolo lotayirira.

Momwe mungadziwire cholakwika P0479?

Kuti muzindikire DTC P0479, njira zotsatirazi zikulimbikitsidwa:

1. Onani zolakwika: Gwiritsani ntchito sikani yowunikira kuti muwerenge nambala ya P0479 ndi ma code ena ovuta omwe angakhale atawonekera. Lembani zizindikiro zolakwika kuti muwunikenso.
2. Kuyang'ana kowoneka: Yang'anani valavu yotulutsa mpweya wotulutsa mpweya ndi zolumikizira zonse zamagetsi kuti muwone kuwonongeka, dzimbiri, kapena mawaya osweka. Onetsetsani kuti zolumikizira zonse ndi zotetezeka.
3. Kuyang'ana mayendedwe amagetsi: Yang'anani momwe magetsi amalumikizirana ndi valavu yotulutsa mpweya wotulutsa mpweya kuti mulumikizane bwino ndi dzimbiri. Ngati ndi kotheka, yeretsani zolumikizira ndikulumikizanso mawaya.
4. Kuyeza ma valve othamanga: Gwiritsani ntchito ma multimeter kuti muwone kukana ndi voteji pa valve yotulutsa mpweya wotulutsa mpweya. Onetsetsani kuti kukana kumagwirizana ndi zomwe wopanga amapanga.
5. Kuwona throttle position sensor: Yang'anani sensa ya throttle position kuti igwire bwino ntchito chifukwa ingakhale ikuyambitsa magetsi okwera kapena otsika pamagetsi otulutsa mpweya wotulutsa mpweya.
6. Mayeso owonjezera: Kutengera ndi momwe zinthu ziliri, kuyezetsa kwina kwa makina oyendetsera injini ndi zida zina zotulutsa mpweya zitha kufunikira.
7. Kuwona zida zamakina: Ngati ndi kotheka, fufuzani mkhalidwe wa makina zigawo zikuluzikulu za dongosolo utsi, monga utsi zobwezedwa, utsi dongosolo recirculation mpweya ndi turbocharging.

Pambuyo pozindikira ndi kuzindikira vutolo, ndikofunikira kukonza koyenera kapena kusinthira zida zolakwika.

Zolakwa za matenda

Mukazindikira DTC P0479, zolakwika zotsatirazi zitha kuchitika:

• Dumphani kuyang'ana kowoneka: Cholakwika chikhoza kuchitika ngati kuyang'anitsitsa kowoneka bwino kwa valve yotulutsa mpweya wotulutsa mpweya ndi kugwirizana kwake kwamagetsi sikunachitike. Kudumpha sitepe iyi kungayambitse kuwonongeka kosazindikirika kapena kusweka kwa waya.
• Kuyesa kwazinthu zolakwika: Cholakwikacho chimachitika pamene kuyesa kuchitidwa ndi chida cholakwika kapena njira. Kugwiritsa ntchito ma multimeter molakwika kapena kusamvetsetsa bwino dongosolo kungayambitse malingaliro olakwika.
• Kuwunika kosakwanira kwa sensa ya throttle position: Ngati throttle position sensor sichinayesedwe mokwanira, zingayambitse mavuto osadziwika bwino a magetsi mu mpweya wotulutsa mpweya wothamanga.
• Dumphani mayeso owonjezera: Mavuto ena, monga mavuto a makina oyendetsa injini kapena kuwonongeka kwa makina opangira mpweya, akhoza kuphonya panthawi ya matenda ngati mayesero owonjezera ndi kufufuza sikukuchitika.
• Kutanthauzira molakwika kwa data: Cholakwikacho chimachitika pamene zotsatira za mayeso zimatanthauziridwa molakwika kapena kunyalanyazidwa. Kusaganizira mokwanira mwatsatanetsatane kapena kutanthauzira kolakwika kwa deta kungayambitse malingaliro olakwika ponena za zomwe zimayambitsa kulephera.

Kuti muzindikire bwino, muyenera kuwunika mosamala magawo onse a njirayi, kugwiritsa ntchito njira ndi zida zolondola, ndikuyesa mayeso onse ofunikira ndikuwunika kuti mudziwe chomwe chayambitsa vutoli.

Kodi zolakwika ndizovuta bwanji? P0479?

Khodi yamavuto P0479 ikuwonetsa vuto ndi valavu yamagetsi yotulutsa mpweya, yomwe ingasokoneze magwiridwe antchito a injini. Ngakhale kuti iyi si vuto lalikulu, imafunikabe kusamala komanso kukonzedwa mwamsanga.

Ngati mpweya wotulutsa mpweya wotulutsa mpweya sukugwira ntchito bwino, ukhoza kuchititsa kuti dongosolo la EGR lisagwire ntchito ndipo pamapeto pake lidzasokoneza kayendedwe ka galimoto. Kuphatikiza apo, zingayambitsenso kuchepa kwa magwiridwe antchito a injini komanso kuchuluka kwamafuta.

Ngakhale kuti P0479 si yadzidzidzi, tikulimbikitsidwa kuti ikonzedwe mwamsanga kuti tipewe mavuto owonjezera komanso kusunga kayendetsedwe kabwino ka galimoto.

Ndi kukonza kotani komwe kungathetse nambala ya P0479?

Kuti muthetse DTC P0479, chitani zotsatirazi:

1. Kuyang'ana dera lamagetsi: Choyamba, muyenera kuyang'ana dera lamagetsi lomwe limagwirizanitsa valavu yotulutsa mpweya wamagetsi ku injini yoyendetsera injini (PCM). Yang'anani kukhulupirika kwa mawaya, zolumikizira ndi zolumikizira za dzimbiri, zowonongeka kapena zosweka.
2. Kuwona valavu yowongolera kuthamanga: Kenako, muyenera kuyang'ana valavu yamagetsi yotulutsa mpweya kuti igwire bwino ntchito. Ngati ndi kotheka, valve iyenera kusinthidwa.
3. Diagnostics pogwiritsa ntchito scanner: Kugwiritsa ntchito scanner yowunikira kumakupatsani mwayi kuti muwone momwe ma valve amagwirira ntchito ndikuwona zolephera zilizonse kapena zolephera pakugwira ntchito kwake. Izi zikuthandizani kuti mudziwe bwino chomwe chimayambitsa nambala ya P0479.
4. Kusintha sensor ya pressure: Nthawi zina, chifukwa cha cholakwikacho chikhoza kukhala kusagwira ntchito kwa mpweya wotulutsa mpweya. Ngati izi zatsimikiziridwa panthawi ya matenda, sensa iyi iyenera kusinthidwa.
5. Pulogalamu ya PCM: Nthawi zina, kukonzanso pulogalamu ya injini yoyang'anira (PCM) kungathandize kuthetsa vuto la code P0479.
6. Kuyang'ana machubu a vacuum ndi ma hoses: Yang'anani momwe ma vacuum machubu ndi ma hoses akulumikiza valavu yotulutsa mpweya wotulutsa mpweya kuzinthu zina zamakina. Onetsetsani kukhulupirika kwawo ndi kusakhalapo kwa kutayikira.

Ndibwino kuti muzichita izi motsogozedwa ndi katswiri wodziwa ntchito zamagalimoto kapena katswiri wamagalimoto, makamaka ngati mulibe luso lokonza magalimoto kapena kugwiritsa ntchito makina amagetsi.
