Uhlelo lwe-P2098 Fuel Trim Ngemuva KweCatalyst Too Lean Bank 2

Idatha ye-OBD-II DTC

Uhlelo Olukhululekile Lwe-Fuel Ngemuva KweCatalyst, iBhange 2

Kusho ukuthini lokhu?

Le yikhodi yokudlulisela ejwayelekile okusho ukuthi ihlanganisa konke ukwenziwa / amamodeli kusuka ngo-1996 kuye phambili. Noma kunjalo, izinyathelo ezithile zokuxazulula inkinga zingahluka kusuka emotweni kuya emotweni.

ICode P2098, iPost Catalyst Fuel Trim System Too Lean in Bank 2, imane ifakwa esimweni esinciphile (umoya omningi kakhulu nophethiloli onganele), i-PCM eyibonile kusuka kumasinali avela kuzinzwa ze-oxygen. I-Bank 2 isho ohlangothini lwenjini olungenayo isilinda # 1.

Izinzwa eziningi zokwenza umoya-mpilo kusistimu yokukhipha umoya zihlale zibonisa isilinganiso sikaphethiloli enhlanganisweni. Yonke isistimu yokukhipha umoya ene-catalytic converter izoba nezinzwa ezimbili - eyodwa phakathi kwenjini nesiguquli kanye neyodwa ngemva kwesiguquli.

Izinzwa ze-oksijeni zikhomba kwikhompyutha yokulawula injini inani le-oxygen ekhona ku-exhaust, esetshenziselwa ukunquma nokulawula isilinganiso sephethiloli. Ukuphakama kokuqukethwe komoya-mpilo, ukuncika kwenhlanganisela kaphethiloli, okuphambene nalokho, ingcebo icebile. Lokhu kwenzeka ngendlela yochungechunge lwemiqondo ebizwa ngokuthi "ukubala okuphambene". Echosheni lenzwa kukhona i-zirconium, ephendula umoya-mpilo ngendlela yokuthi izenzele eyayo ingcindezi uma kushisa. Kudingeka ibe cishe ngama-250 degrees Fahrenheit ukuze isebenze futhi ikhiqize kuze kufike ku-0.8 volts.

Ngesikhathi sokusebenza, inzwa ye-oxygen izojikeleza kanye ngomzuzwana futhi inikeze ikhompuyutha nge-voltage esukela ku-0.2 kuya ku-0.8 ngengxube ecebile. Ingxube ekahle izoba nesilinganiso samasignali azungeze ama-volts angu-0.45. Isilinganiso se-fuel ku-air ku-computer singu-14.7: 1. Inzwa ye-oxygen ngeke isebenze emazingeni okushisa aphansi njengokuqalisa - ngenxa yalesi sizathu, izinzwa eziningi zangaphambili zine-preheater ukuze zinciphise isikhathi sazo sokufudumala.

Izinzwa ze-oksijini zinomsebenzi ombaxambili - ukukhombisa umoya-mpilo ongashiswanga ekukhishweni futhi, okwesibili, ukukhombisa impilo yesiguquli se-catalytic. Inzwa eseceleni kwenjini ikhombisa inhlanganisela engena kusiguquli, futhi inzwa yangemuva ikhombisa ingxube ishiya isiguquli.

Lapho izinzwa ne-transducer zisebenza ngokujwayelekile, ikhawunta yenzwa yangaphambili izobe iphakeme kunaleyo yenzwa engemuva, ekhombisa i-transducer enhle. Lapho izinzwa zangaphambili nezingemuva zifanelana, inzwa yomoya-mpilo engaphambili inephutha, isiguquli siminyene, noma enye into idala isignali eyiphutha ye-oxygen sensor.

Le khodi ingahle ingabonakali kakhulu ekukhanyeni kwenjini yokuhlola. Kuya ngesizathu, noma kunjalo ayikho into engahluleka emotweni ngaphandle kokuthinta kabi enye into. Landelela inkinga bese ulungisa ikhodi ngokushesha okukhulu ukugwema ukulimaza ezinye izinto.

izimpawu

Izimpawu zekhodi engu-P2098 zizohluka ngokuya ngengxenye noma isistimu edala ukungasebenzi kahle kukaphethiloli. Akubona bonke abazoba khona ngesikhathi esisodwa.

• Ilampha Yesikhombi Sokungasebenzi (MIL) esikhanyiswe nge-DTC P2098 isethi
• Ikhohlakali
• Umnotho kaphethiloli ombi
• Ukusheshisa okubi
• Ngenelisa
• I-Cherry Red Hot Catalytic Converter
• I-spark detonator engenzeka (ukungqongqoza / ukushisa ngaphambi kwesikhathi)
• Amakhodi angeziwe ahambisana ne-P2098

Izizathu ezingenzeka

Izizathu zale DTC zingafaka:

• Ingcindezi ephansi kaphethiloli ebangelwa isihlungi esivinjelwe, ukungasebenzi kwepompo kaphethiloli, ukwehluleka kokulawula ingcindezi kaphethiloli, noma izihlinzana ezivalekile noma ezivuzayo.
• Injini ekhohlakele egijima ngenxa yamaphutha we-plug plug. Izinjini eziningi zinamakhodi we-misfire ukukhombisa ukuthi iyiphi ukwehluleka okwenzekile, njenge-P0307 yenombolo 7.
• Ukuvuza okukhulu kwe-vacuum kuzodala ukuthi inani elikhulu lomoya elingalinganisiwe lingene kokuphindaphindwayo kokudla, okuholele enhlanganisweni encike ngokweqile.
• Ukuvuza okukhulu komoya ngaphakathi noma eduze kwenzwa yokuqala yomoya-mpilo nakho kungadala ingxube enciphile.
• Isiguquli esixhunyiwe sizodala izinkinga eziningi zokushayeleka futhi sizofaka le khodi. Isiguquli esivaleke kakhulu sizokwenza kungenzeki ukukhuphula i-rpm ngaphansi komthwalo. Bheka ikhodi efana ne-P0421 - Ukusebenza kahle kwesiguquli se-Catalytic ngaphansi komkhawulo uma isiguquli sibonisa isiguquli esinephutha.
• Inzwa ye-oxygen engaphelele. Lokhu kuzosetha ikhodi ngokwayo, kepha inzwa ye-oxygen engalungile ayiyikhubazi ngokuzenzakalela inzwa ye-oxygen. Ikhodi isho nje ukuthi isignali yenzwa iphelelwe yimininingwane. Ukuvuza komoya noma okunye kwalokhu okungenhla kuzokhiqiza isignali eyiphutha. Kunamakhodi amaningi we-O2 aphathelene nezici ze-O2 akhombisa indawo enenkinga.
• Inzwa yokugeleza komoya enkulu nayo izobangela le nkinga. Lokhu kuzohambisana nekhodi efana ne-P0100 - I-Mass Air Flow Circuit Malfunction. Inzwa yokugeleza komoya omkhulu iyintambo eshisayo ethola inani lomoya ongena endaweni eningi. Ikhompyutha isebenzisa lolu lwazi ukulawula ingxube kaphethiloli.
• Amasistimu wokukhipha abuthuntu, izinqwaba ze-exhaust eziqhekekile, ama-gaskets alimele noma alahlekile, noma ama-donuts azodala ukuvuza komoya.

Ukunquma imbangela nomphumela wezimoto, cabanga ngalesi simo. Ukuvuza komoya okulula phambi kwenzwa yokuqala yomoya-mpilo kuzongeza umoya owengeziwe enhlanganisweni, engalinganiswa ikhompyutha. Inzwa ye-oxygen isayina ingxube enciphile ngenxa yokushoda kwesikali somoya.

Ngokushesha, ikhompyutha iyayinothisa ingxube ukuvimbela ukulimala kwengxube enciphile ngenxa yokuqhuma, phakathi kwezinye izinto. Ingxube ecebe ngokweqile iqala ukuvala amakhandlela, ingcolise uwoyela, ishise isiguquli futhi inciphise ukusetshenziswa kukaphethiloli. Lezi ngezinye nje zezinto ezimbalwa ezenzeka kulezi zimo.

Izinqubo zokuxilonga nokulungisa

Kuyalulekwa ukuthi ungene ku-inthanethi futhi uthole ama-Technical Service Bulletins (TSB) ahambisana nalawa makhodi nezincazelo. Ngenkathi zonke izimoto zinembangela efanayo, ezinye zingaba nomlando wensizakalo wezinkinga ngengxenye ethile ehambisana naleyo khodi.

Uma ukwazi ukufinyelela kuthuluzi lokuskena eliphambili njenge-Tech II noma i-Snap-On Vantage, izokugcinela isikhathi esiningi. Isithwebuli singagrafu futhi sibonise imininingwane yedijithali mayelana nokusebenza kwenzwa ngayinye ngesikhathi sangempela. Izokhombisa izinzwa zomoya-mpilo ezisebenza kalula ukuthi zibone kalula iphutha.

AmaJeeps neminye imikhiqizo yeChrysler kubonakala sengathi ihlushwa izixhumi zikagesi ezingezinhle, ngakho-ke zihlole ngokucophelela. Ngaphezu kwalokho, iJeep ibe nokuthuthukiswa okuningana kwe-PCM kumamodeli wakamuva. Ukulungiswa kabusha kokuhlelwa kabusha kanye nokufaka inzwa yomoya-mpilo nganoma yisiphi isizathu kumbozwe iwaranti yeminyaka eyi-8 / 80,000 yamamayela. Ukubheka ukuthi ngabe ukuvuselelwa kuqediwe, bheka eduze noma ngemuva kwebhethri futhi kuzoba nenombolo ye-serial nosuku ikhompyutha eyabuyekezwa ngalo. Uma kungakenziwa, kumahhala isikhathi esibekiwe.

• Xhuma isithwebuli sekhodi kukhodi ye-OBD ngaphansi kwedeshibhodi. Vula ukhiye endaweni ethi "Vuliwe" injini icishiwe. Chofoza inkinobho ethi "Funda" bese amakhodi azokhonjiswa. Xhuma noma yimaphi amakhodi angeziwe kuthebula lekhodi elifakiwe. Naka lawa makhodi kuqala.
• Esikhundleni samakhodi angeziwe ahambisana nekhodi engu-P2096 noma i-P2098, hlola ukushayela imoto bese ubheka izimpawu zokulawula. Ukungcoliswa kukaphethiloli kuzoqala le khodi. Faka isigaba esiphakeme.
• Uma imoto ikhombisa amandla amancane kakhulu nobunzima ukushesha, bheka ngaphansi kwemoto lapho injini isebenza. Isiguquli esivimbekile ngokuvamile sikhanya kubomvu.
• Bheka injini ukuvuza kwesikhala phakathi kwenzwa ye-MAF nokuphindaphindeka kokudla. Ukuvuza kuvame ukuzwakala njengempempe. Susa noma yikuphi ukuvuza bese uhlanza ikhodi.
• Uma injini ikhombisa ukungahambi kahle futhi bekungekho ikhodi, nquma ukuthi imuphi usilinda odonsa kabi. Uma okuthengiswayo kuphindaphindeka kubonakala, fafaza noma uthele inani elincane lamanzi ekuphumeni kwesilinda ngasinye. Amanzi azohwamuka ngokushesha kumasilinda anempilo futhi kancane kumasilinda alahlekile. Uma lokhu kungenzeki, susa ama-plugs bese uhlola isimo.
• Bheka izintambo ze-plug ukuze uqiniseke ukuthi azishisi noma zilele esikhunjeni.
• Hlola uhlelo lokukhipha. Bheka izimbobo zokugqwala, ama-gaskets alahlekile, imifantu noma ukuxegisa. Phakamisa imoto bese usebenzisa i-wrench 7/8 ”ukuqinisekisa ukuthi inzwa ye-oxygen iyaqiniswa. Hlola i-harness yocingo nesixhumi.
• Uma kukhonjiswa ikhodi ye-MAF, hlola isixhumi sayo. Uma kulungile, shintsha inzwa ye-MAF.
• Faka inzwa yomoya-mpilo etholakala ezansi nomshintshi we-catalytic ngasohlangothini lwenjini ngaphandle kwesilinda # 1. Ngaphezu kwalokho, uma ikhodi yenzwa yomoya-mpilo ibika "ukungasebenzi kahle kwe-heater", inzwa kungenzeka ukuthi ayisebenzi.
