I-P0404 Exhaust Gas Recirculation Circuit Out of Range / Performance

Idatha ye-DTC P0404-OBD-II

Exhaust Gas Recirculation "A" Ibanga / Ukusebenza

Isho ukuthini ikhodi yenkinga P0404?

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.

Uhlelo lokukhishwa kabusha kwegesi lokukhipha lwenzelwe ukuqondisa kabusha amagesi okukhipha abuyele kumasilinda. Njengoba amagesi e-exhaust engena ngaphakathi, asusa umoya-mpilo nophethiloli, ngaleyo ndlela anciphise izinga lokushisa emasilindini, nawo anciphisa ukukhishwa kwe-nitrogen oxide. Ngalesi sizathu, kufanele ifakwe ngokucophelela kumasilinda (nge-valve yokukhipha igesi) ukuze ingaphazamisi ukusebenza kwenjini. (I-EGR eningi kakhulu nenjini ngeke isebenze).

Uma une-P0404, i-valve ye-EGR kungenzeka ibe yiveluvu ye-EGR elawulwa ngogesi hhayi i-valve elawulwa nge-EGR. Ngaphezu kwalokho, i-valve ivamise ukuba nohlelo lwempendulo olwakhelwe ngaphakathi olutshela i-PCM (Powertrain Control Module) ukuthi ikuphi i-valve; kuvulekile, kuvaliwe noma kwenye indawo phakathi. I-PCM kumele ikwazi lokhu ukuze ithole ukuthi i-valve isebenza kahle yini. Uma i-PCM inquma ukuthi i-valve kufanele isebenze kodwa iluphu yempendulo ikhombisa ukuthi i-valve ayivuliwe, le khodi izosethwa. Noma, uma i-PCM inquma ukuthi i-valve kufanele ivalwe, kepha isignali yempendulo ikhomba ukuthi i-valve ivulekile, le khodi izosethwa.

Izimpawu

I-DTC P0404 kungenzeka ingakhombisi noma yiluphi uphawu ngaphandle kwe-MIL (Lamp Indicator) noma i-Check Engine Light. Kodwa-ke, amasistimu e-EGR anenkinga ngokwemvelo ngenxa yokwakheka kwekhabhoni kokuphindaphindwayo kokudla, njll. Lokhu kwakha okujwayelekile kungakha ku-valve ye-EGR, kuyigcine ivulekile lapho kufanele ivalwe. Kulokhu, injini ingahle ingenzi lutho noma cha. Uma i-valve yehluleka futhi ingavuli, izimpawu zingaba amazinga okushisa aphezulu omlilo futhi, ngenxa yalokho, ukukhishwa okuphezulu kwe-NOx. Kepha izimpawu zokugcina ngeke zibonakale kumshayeli.

Izimbangela zephutha P0404

Imvamisa, le khodi ikhombisa ukwakheka kwekhabhoni noma i-valve engalungile ye-EGR. Noma kunjalo, lokhu akubeki eceleni okulandelayo:

• Isifunda esivulekile noma esifushane kumjikelezo wesithenjwa we-5V
• Isifunda esivulekile noma esifushane esifundeni somhlabathi
• Isifunda esivulekile noma esifushane kusifunda se-PCM esibhekiwe samandla kagesi
• I-PCM engalungile (mancane amathuba okuthi)

Izixazululo ezingenzeka

1. Yala i-valve ye-EGR ivulwe ngethuluzi lokuskena ngenkathi ubheka isikhundla sangempela se-EGR (kungenzeka ibhalwe ukuthi "I-EGR efiselekayo" noma into efanayo). Indawo yangempela ye-EGR kufanele ibe seduze kakhulu nendawo "efunwayo" ye-EGR. Uma kunjalo, inkinga kungenzeka ukuthi yesikhashana. Kungenzeka kube ucezu lwekhabhoni olunamathele obelulokhu lushintsha kusukela lapho, noma kungaba ikhoyili ye-valve ye-EGR enamaphutha evula noma ivala ngezikhathi ezithile lapho izinga lokushisa kwe-valve liguquka.
2. Uma indawo "oyifunayo" ye-EGR ingasondeli endaweni "yangempela", nqamula inzwa ye-EGR. Qiniseka ukuthi isixhumi sinikezwa ngereferensi engu-5 volt. Uma ingakhombisi isethenjwa samandla kagesi, lungisa okuvulekile noma okufushane kusekethe yesithenjwa esingu-5 V.
3. Uma ireferensi ye-volt engu-5 itholakala, yenza kusebenze i-EGR ngeskena, qapha isekethe lomhlabathi le-EGR nge-DVOM (i-digital volt / ohmmeter). Lokhu kufanele kukhombise isisekelo esihle. Uma kungenjalo, lungisa isifunda somhlabathi.
4. Uma kunendawo enhle, hlola isekethe yokulawula. Kufanele ikhombise i-voltage eyahluka ngamaphesenti avulekile e-EGR. Lapho ivuleka ngokwengeziwe, kufanele lenyuke ngamandla i-voltage. Uma kunjalo, shintsha i-valve yokukhipha igesi.
5. Uma i-voltage ingakhuphuki kancane, lungisa okuvulekile noma okufushane kusifunda sokulawula se-EGR.

Amakhodi E-EGR Ahlanganisiwe: P0400, P0401, P0402, P0403, P0405, P0406, P0407, P0408, P0409

Umakhenikha uyihlonza kanjani ikhodi ye-P0404?

• Ukuskena amakhodi namadokhumenti kumisa idatha yozimele ukuze kuqinisekiswe inkinga
• Isula amakhodi enjini nokuhlolwa komgwaqo ukubona ukuthi inkinga iyabuya yini
• Igada i-pid yenzwa ye-EGR kusikena ukuze ibone ukuthi ingabe inzwa ikhombisa ukuthi ivalvu ibhajwe ivuliwe noma ayinyakazi kahle.
• Ikhipha inzwa ye-EGR futhi isebenzise inzwa mathupha ukuze ihlukanise i-valve noma ukungasebenzi kahle kwenzwa.
• Isusa futhi ihlole i-valve ye-EGR ukuze kuqinisekiswe ukuthi ayiphekanga, okubangela ukufundwa kwenzwa okungalungile.

Amaphutha Avamile Lapho Uhlonza Ikhodi P0404

• Ungayisebenzisi mathupha inzwa yendawo ye-EGR ukuze uhlukanise i-valve noma ukwehluleka kwenzwa ngaphambi kokushintsha izingxenye.
• Ukuhluleka ukuhlola izintambo zokuhlanganisa nokuxhunywa kwenzwa yendawo ye-EGR ngaphambi kokufaka inzwa yendawo ye-EGR noma i-valve ye-EGR.

Ibucayi kangakanani ikhodi ye-P0404?

• Isistimu ye-EGR esebenzisa le khodi, i-ECM ingakhubaza isistimu ye-EGR futhi iyenze ingasebenzi.
• Isibani se-Check Engine esikhanyayo sibangela imoto ukuthi ingaphumeleli ekuhlolweni kokukhishwa kwekhabhoni.
• Isikhundla se-EGR sibalulekile ukuze i-ECM ilawule kahle ukuvulwa nokuvalwa kwe-valve ye-EGR.

Yiziphi izilungiso ezingalungisa ikhodi P0404?

• Ukushintsha i-valve ye-EGR uma ibhajwe kancane ivuliwe ngenxa yomsizi endaweni yephini futhi ayikwazi ukuhlanzwa.
• Ishintsha inzwa yendawo ye-EGR uma itholwa ukuthi ayikwazi ukunikeza okokufaka okulungile ku-ECM lapho ihanjiswa ngesandla
• Lungisa izintambo ezimfushane noma ezivuliwe kunzwa yendawo ye-EGR noma isixhumi.

Amazwana engeziwe okufanele acatshangelwe mayelana nekhodi P0404

Ikhodi P0404 iqalwa lapho isikhundla se-EGR singenjengoba bekulindelekile yi-ECM futhi imbangela evame kakhulu ivalvu ye-EGR evaleleke ngokwengxenye ngenxa yediphozithi yekhabhoni kuphinikhodi.

Udinga usizo olwengeziwe ngekhodi le-p0404?

Uma usadinga usizo nge-DTC P0404, 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.
