I-P0421 Catalyst Ukuzifudumeza Ukusebenza Ngezansi Kwesilinganiso

I-OBD-2 - P0421 - Incazelo Yobuchwepheshe

P0421 - Ukusebenza kahle kweCatalyst Heating Ngezansi kweThreshold (Ibhange 1)

Ikhodi P0421 isho ukuthi imojula yokulawula ukudlulisa inquma ukuthi isistimu yokuguqula i-catalytic ayisebenzi kahle ngesikhathi sokufudumala. Lesi sikhathi sizoqhubeka kusukela lapho imoto iqalwa okokuqala kuze kube yimizuzu emihlanu kuya kweyishumi kamuva.

Isho ukuthini ikhodi yephutha P0421?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezihlomele i-OBD-II. Yize kuvamile emvelweni, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli.

Lokhu ngokuyisisekelo kusho ukuthi inzwa ye-O1 engezansi kwesiguquli se-catalytic e-Unit XNUMX ithola ukuthi isiguquli asisebenzi kahle njengoba kufanele (njengokucaciswa ngakunye). Kuyingxenye yohlelo lokukhishwa kwemoto.

Imojula yokulawula i-powertrain isebenzisa idatha evela kuzinzwa zomoya-mpilo ezikhuphuka nomfula futhi iqhathanisa ukufundwa kokubili. Uma ukufundwa okubili kufana noma kusondelene kakhulu, ukukhanya kwe-Check Engine kuzokhanya futhi ikhodi P0421 izogcinwa. Uma le nkinga yenzeka kuphela ngenkathi imoto ifudumala, ikhodi P0421 izogcinwa.

Izimpawu

Ngeke uzibone izinkinga zokuphatha, noma ngabe zikhona izimpawu. Ikhodi ingahle ivele ngemuva kokuthi injini iqale kaningi injini ebandayo ezinsukwini ezi-1 kuya kwezi-2 ezedlule.

• Isibani se-Check Engine sizokhanya
• Injini kungenzeka ingaqali
• Injini ingase ingabi namandla noma inyakaze uma ishesha
• Imisindo eyinqaba ingase izwakale ngenkathi ushayela

Izizathu zephutha P0421

Ikhodi ye-P0421 ingasho ukuthi umcimbi owodwa noma eminingi yenzekile:

• Isiguquli se-catalytic asisasebenzi kahle
• Inzwa ye-oxygen ayifundi (ayisebenzi) kahle
• Inhlansi iplagi ingcolile
• Isiguquli se-catalytic esinephutha (okungenzeka kakhulu uma engekho amanye amakhodi agciniwe)
• Inzwa ye-oxygen enephutha
• Isekhethi yenzwa yomoya-mpilo eyonakele
• Imojuli yokulawula i-powertrain enephutha

Izixazululo ezingenzeka

Linganisa i-voltage kunzwa ye-oxygen ku-block 1 (inzwa engemuva noma inzwa ngemuva kwe-transducer). Eqinisweni, kungaba umqondo omuhle ukuhlola yonke inzwa ye-O2 oxygen ngenkathi ukuyo.

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 P0421?

Uma ikhodi P0421 bekuwukuphela kwekhodi egcinwe ohlelweni, umakhenikha angakwazi ukuxilonga inkinga ngokubheka isistimu yokukhipha umoya. Ukuhlola okubukwayo kuhlale kuyisiqalo esingcono kakhulu sokuxilonga imoto.

Umakhenikha angenza izinto ezimbalwa ukuze ahlole isimo seziguquli ze-catalytic, njengokuhogela i-exhaust ukuze ahlole uphethiloli oweqile, ukuhlola iziguquli ze-catalytic ukuthi zibomvu yini uma injini isebenza, nokuhlola umgwaqo imoto ukuze kuqinisekiswe izimpawu.

Uma ukuhlolwa okubukwayo kuqinisekiswa, umakhenikha angaqhubeka nokuhlola izinzwa ze-oxygen kanye nemojula yokulawula i-powertrain, aqale ngezinzwa. Uma noma yiziphi izinzwa ze-oxygen zihluleka, zizoshintshwa ngesicelo sekhasimende.

AMAPHUTHA AVAMILE LAPHO KUHLOLWA IKHODI P0421

Iphutha elivamile umakhenikha angalenza lapho exilonga ikhodi engu-P0421 ukweqa ukuxilonga okugcwele futhi esikhundleni sesiguquli se-catalytic. Yize lokhu kuyimbangela okungenzeka kakhulu yekhodi ye-P0421, akusona ukuphela kwesizathu futhi noma iyiphi enye into engenzeka kufanele ikhishwe ngaphambi kokufaka noma yiziphi izingxenye. Lokhu kuyiqiniso ikakhulukazi uma ucabangela ukuthi iziguquli ze-catalytic ngokuvamile ziyingxenye ebiza kakhulu yesistimu yonke yokukhipha umoya.

IYIZINKANI IKHODI P0421?

Ikhodi P0421 ingaba bucayi kakhulu. Uma isiguquli se-catalytic sihlulekile futhi injini ingasebenzi kahle, ukunyakaza okuqhubekayo kwemoto kungabangela ukulimala okukhulu kwenjini. Ukuze injini isebenze kahle, kufanele iphefumule ngendlela evamile. Uma i-catalytic converter incibilike izingxenye zangaphakathi noma ivalwe ngomsizi, injini ngeke ikwazi ukuphefumula kahle ngakho-ke ngeke isebenze kahle.

YIKUPHI UKULUNGISA ONGALUNGISA IKHODI P0421?

Ukulungiswa okungase kulungise ikhodi P0421 kungase kuhlanganise:

• Ukuguqula isiguquli esinamandla
• Shintshanisa inzwa ye-oxygen
• Ukulungisa noma ukushintshwa kwezintambo ezihlobene nenzwa ye-oxygen
• Faka esikhundleni semojuli yokulawula i-powertrain

IMIBONO ENGEZIWE KUKHODI P0421?

Uma isiguquli se-catalytic sinesici, kubalulekile ukufaka ingxenye yaso esikhundleni saso. Abanye abakhiqizi be-aftermarket catalytic converter bakhiqiza izingxenye ezishibhile futhi bangase bahluleke ngaphambi kwesikhathi. Njengoba ukufaka esikhundleni isiguquli se-catalytic ngokuvamile kuvame ukusebenza kanzima, kuwumqondo omuhle ukutshala ingxenye yekhwalithi ukuze uqinisekise ukuthi umsebenzi wenziwa kanye kuphela.

Udinga usizo olwengeziwe ngekhodi le-p0421?

Uma usadinga usizo nge-DTC P0421, 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.
