Ukusebenza kahle kohlelo lwe-P0420 Ngezansi Kwesibopho

Incazelo yobuchwepheshe yephutha P0420

Ukusebenza Kwesistimu Ye-Catalyst Ngaphansi Komkhawulo (Ibhange Loku-1)

Isho ukuthini ikhodi P0420?

Le Khodi Yenkinga Yokuxilonga (i-DTC) iyikhodi ejwayelekile yokudlulisela. Ibhekwa njengendawo yonke njengoba isebenza kuzo zonke izinhlobo zezimoto (1996 nezintsha), nakuba izinyathelo ezithile zokulungisa zingahluka kancane kuye ngemodeli. Ngakho-ke lesi sihloko esinamakhodi enjini sisebenza kwaNissan, Toyota, Chevrolet, Ford, Honda, GMC, Subaru, VW, njll.

I-P0420 ingenye yamakhodi ajwayelekile ezinkinga esiwabonayo. Amanye amakhodi adumile ahlanganisa i-P0171, i-P0300, i-P0455, i-P0442, njll. Ngakho-ke qiniseka ukuthi ubeka uphawu lokubekisa leli sayithi ukuze uthole inkomba yesikhathi esizayo!

Isiguquli se-catalytic siyingxenye yesistimu yokukhipha umoya ebukeka njenge-muffler, nakuba ukusebenza kwayo kuhluke kakhulu kulokho kwe-muffler. Umsebenzi we-catalytic converter ukunciphisa ukukhishwa kwe-exhaust.

Isiguquli se-catalytic sinenzwa ye-oxygen ngaphambili nangemuva. Lapho imoto ifudunyezwa futhi isebenza ngemodi ye-loop evaliwe, ukufundwa kwesiginali kwenzwa ye-oksijini engenhla kufanele kuguquke. Ukufundwa kwenzwa esezansi kwe-O2 kufanele kuzinze ngokufanele. Imvamisa, ikhodi ye-P0420 izokhanyisa ilambu lenjini yokuhlola uma ukufundwa kwezinzwa ezimbili kuyafana. Izinzwa ze-oksijeni zibizwa nangokuthi izinzwa ze-O2.

Lokhu kukhombisa (phakathi kwezinye izinto) ukuthi isiguquli asisebenzi kahle njengoba kufanele (ngokusho kokucacisiwe). Abaguquli beCatalytic ngokuvamile abahlukaniswa "njengokuguga," okusho ukuthi abagugi futhi abadingi ukushintshwa. Uma behlulekile, kungenzeka ukuthi kungenxa yokunye okuholele ekuphahlazekeni. Yilokhu okushiwo yi-P0420 ngendlela eyenziwe lula.

Izimpawu zephutha P0420

Uphawu oluyinhloko lomshayeli yi-MIL ekhanyisiwe. Cishe ngeke uqaphele izinkinga zokuphatha, noma ngabe zikhona izimpawu. Isibonelo, uma into engaphakathi kwesiguquli se-catalytic iphukile noma ingekho esimeni, ingavimbela ukukhishwa kwamagesi e-exhaust, okuholele ekuzweleni kokuncipha kwamandla kagesi wemoto.

• Azikho izimpawu eziphawulekayo noma izinkinga zokusingatha (ezivame kakhulu)
• Qiniseka ukuthi ilambu lenjini livuliwe
• Awekho amandla ngemva kokufudumala kwemoto
• Isivinini semoto asikwazi ukudlula ku-30-40 mph
• Iqanda elibolile lihogela i-exhaust

Izimbangela zephutha P0420

Ikhodi ye-P0420 ingasho ukuthi umcimbi owodwa noma eminingi yenzekile:

• Uphethiloli oholile osetshenzisiwe lapho kudingeka khona uphethiloli ongenamkhondo (akunakwenzeka)
• Inzwa ye-oxygen / O2 eyonakele noma ehlulekile
• Intambo ye-oxygen engezansi kwe-oxygen (HO2S) yonakele noma ixhunywe ngokungalungile
• Inzwa yokushisa yesinjini engasebenzi kahle
• Okonakalisiwe noma okuvuzayo qeda ezininginingi / isiguquli se-catalytic / i-muffler / ipayipi lokukhipha
• Isiguquli esisebenza ngokungasebenzi kahle noma esanele (mhlawumbe)
• Ukubambezeleka kwesimiso
• Izinzwa ze-oksijini ngaphambili nangemuva kwesidlulisi zinikeza ukufundwa okufanayo.
• Umjovo wephethiloli ovuzayo noma umfutho ophakeme kaphethiloli
• Gcwalisa isilinda
• Ukungcoliswa kukawoyela

Izixazululo ezingenzeka

Ezinye zezinyathelo ezinconyiwe zokuxazulula inkinga nokulungisa ikhodi ye-P0420 zifaka:

• Bheka ukuvuza kokukhipha ezinhlotsheni eziningi, amapayipi, isiguquli sokulawula. Lungisa uma kunesidingo.
• Sebenzisa i-oscilloscope ukuxilonga inzwa ye-oxygen (Ukusikisela: inzwa yomoya-mpilo phambi kwesiguquli se-catalytic imvamisa ine-waveform eshintshashintshayo. I-waveform sensor ngemuva kwesiguquli kufanele izinze kakhudlwana).
• Hlola inzwa ye-oxygen evuthayo ephansi bese uyishintsha uma kunesidingo.
• Faka esikhundleni sokuguqula okuguqukayo.

Iseluleko sokuxilonga

Ngokuvamile, ungabuka izinga lokushisa qeda ngaphambi nje futhi ngokushesha ngemuva kwesiguquli nge-thermometer ye-infrared. Lapho injini ifudunyezwa ngokuphelele, izinga lokushisa okufanele liphume kufanele libe cishe ngama-100 degrees Fahrenheit ngaphezulu.

Sekukonke, iphutha elikhulu kakhulu elenziwa abanikazi bezimoto uma benekhodi ye-P0420 ukumane bamiselele inzwa ye-oxygen (inzwa 02). Kubalulekile ukuxilonga ngendlela efanele ukuze ungachithi imali ezingxenyeni ezishintshwayo ezingadingekile.

Sincoma ngokuqinile ukuthi uma udinga ukushintsha isiguquli se-catalytic, esikhundleni saso ufake idivayisi yomkhiqizo womkhiqizi wangempela (okungukuthi, thola esitolo). Inketho yesibili ingxenye eshintshayo yekhwalithi, njengekati elisemthethweni lezifundazwe ezingama-50. Ziningi izindaba ezinkundleni zethu zabantu abashintsha ikati bafake i-aftermarket eshibhile bese bebuyisela ikhodi maduze nje.

Kumele kuqashelwe ukuthi abakhiqizi abaningi bezimoto banikela ngeziqinisekiso ezinde zezingxenye ezihlobene nokukhishwa. Ngakho-ke, uma unemoto entsha kodwa ungamboziwe yibhampasi le-bumper-to-bumper, kungahle kube khona iwaranti yalolu hlobo lwenkinga. Abakhiqizi abaningi banikeza le mikhiqizo iwaranti yeminyaka emihlanu engenamkhawulo. Kuyafaneleka ukuphuma.

IYENZA KANJANI IKHODI YE-MCHHANIC DIAGNOSTIC P0420?

• Sebenzisa iskena se-OBD-II ukuze ubuyise amakhodi enkathazo agciniwe ku-PCM.
• Ibonisa idatha ebukhoma yenzwa ye-oxygen engezansi (engemuva). Ukufundwa kwe-voltage yenzwa ye-oxygen engezansi kufanele kuhlale njalo. Nquma ukuthi ingabe inzwa ye-oxygen engezansi (engemuva) isebenza kahle yini.
• Thola noma imaphi amanye amakhodi okungenzeka abangela i-DTC P0420.
• Lungisa ukungafihli kahle, ukudubula kabi kanye/noma izinkinga zesistimu kaphethiloli njengoba kudingeka.
• Ihlola inzwa ye-oxygen yangemuva ukuze ibone umonakalo kanye/noma ukuguga okudlulele.
• Ukuhlola ukushayela imoto kubheka idatha yozimele wokufriza ukuze kutholwe ukuthi ingabe inzwa yomoya-mpilo engezansi (engemuva) isebenza kahle yini.
• Bheka izibuyekezo ze-PCM ezitholakalayo uma isiguquli se-catalytic sinephutha. Ngemva kokushintsha isiguquli se-catalytic, izibuyekezo ze-PCM zizodingeka.

AMAPHUTHA AVAMILE LAPHO KUHLOLWA IKHODI P0420

Iphutha elivame kakhulu ukufaka izinzwa ze-oxygen ngaphambi kokuba inqubo yokuxilonga iqedwe. Uma enye ingxenye ibangela ikhodi yenkathazo ye-P0420, ukufaka esikhundleni sezinzwa zomoya-mpilo ngeke kulungise inkinga.

IYIZINKANI IKHODI P0420?

Kuvamile ukuthi umshayeli angabi nazinkinga zokusingatha lapho i-P0420 DTC ikhona. Ngaphandle kokukhanyisa kwe-Check Engine, izimpawu zale DTC zingase zinganakwa. Kodwa-ke, uma imoto ishiywe ngephutha ngaphandle kokuxazulula inkinga, ingabangela umonakalo omkhulu kwezinye izingxenye.

Njengoba zingekho izimpawu zokuphatha izinkinga ezihlobene ne-DTC P0420, lokhu akubhekwa njengokubi noma kuyingozi kumshayeli. Kodwa-ke, uma ikhodi ingalungiswa ngesikhathi, isiguquli se-catalytic singalimala kakhulu. Ngenxa yokuthi ukulungiswa kwesiguquli se-catalytic kuyabiza, kubalulekile ukuthi i-DTC P0420 ixilongwe futhi ilungiswe ngokushesha okukhulu.

YIKUPHI UKULUNGISA ONGALUNGISA IKHODI P0420?

• Faka esikhundleni se-muffler noma lungisa ukuvuza kwe-muffler
• Faka esikhundleni se-exhaust eninginingi noma lungisa ukuvuza okuphindaphindiwe kwe-exhaust.
• Shintsha ipayipi lokudonsa amanzi noma lungisa ukuvuza kwepayipi lokudonsa amanzi.
• Faka esikhundleni isiguquli se-catalytic (esivame kakhulu)
• Faka esikhundleni Inzwa Yezinga Lokushisa Elipholisa Injini
• Ukushintsha inzwa ye-oxygen yangaphambili noma yangemuva
• Lungisa noma shintsha izintambo ezilimele kuzinzwa ze-oxygen.
• Lungisa noma shintsha izixhumi zenzwa ye-oxygen
• Shintsha noma lungisa ama-injection kaphethiloli avuzayo
• Ukuxilonga noma yiziphi izinkinga ezingalungile
• Thola futhi ulungise noma yimaphi amanye amakhodi ezinkinga ahlobene agcinwe imojuli yokuphathwa kwamandla (PCM).

IMIBONO ENGEZIWE UKUZE UQAPHELE IKHODI P0420

Izinkinga ngesistimu yokubasa, isistimu kaphethiloli, ukungena komoya, nemililo engalungile ingalimaza isiguquli se-catalytic uma singaxazululwanga ngokushesha. Lezi zingxenye ziyimbangela evame kakhulu ye-DTC P0420. Uma ushintsha isiguquli se-catalytic, kunconywa ukuthi esikhundleni saso ufake iyunithi yoqobo noma inzwa ye-oxygen yekhwalithi ephezulu.

Izinzwa zomoya-mpilo ze-Aftermarket zivame ukwehluleka, futhi uma lokhu kwenzeka, ikhodi yenkinga ye-P0420 ingaphinda ivele. Kufanele futhi uxhumane nomkhiqizi ukuze ubone ukuthi imoto yakho imbozwe yini iwaranti yomkhiqizi ezingxenyeni ezihlobene nokukhishwa kwesisi.

Udinga usizo olwengeziwe ngekhodi le-p0420?

Uma usadinga usizo nge-DTC P0420, thumela umbuzo kumazwana angezansi kwalesi sihloko.

QAPHELA. Lolu lwazi lunikezwa ngenhloso yokwaziswa kuphela. Akuhloselwe ukuthi isetshenziswe njengesincomo sokulungisa futhi asinacala nganoma yisiphi isenzo osithathayo kunoma iyiphi imoto. Yonke imininingwane ekulesi siza ivikelwe yi-copyright.
