P2099 Post Catalyst Fuel Trim System Yolemera Bank 2

Mapepala a OBD-II DTC

Chepetsani Dongosolo Pambuyo Pazinthu Zambiri Bank 2

Kodi izi zikutanthauzanji?

Izi Diagnostic Trouble Code (DTC) ndi njira yofalitsira, zomwe zikutanthauza kuti imagwira ntchito pagalimoto zonse kuyambira 1996 (Ford, Dodge, GMC, Chevrolet, Mercedes, VW, etc.). Ngakhale ndizachilengedwe, njira zowongolera zimatha kusiyanasiyana kutengera mtundu / mtundu.

Nthawi zonse ndikathamangira mu P2099 DTC ndikudziwa kuti gawo lowongolera la powertrain (PCM) lazindikira voteji yamagetsi kuchokera kumunsi (pambuyo pa catalytic) oxygen (O2) sensor ya banki yoyamba ya injini, zomwe zikuwonetsa kuti zomwe zili mu oxygen. particles ndi otsika kwambiri. Bank 2 ndi gulu la injini lomwe lilibe silinda # 1.

Chojambulira cha O2 chimakhala ndi zirconia sensing element yotsekedwa munyumba yazitsulo zopumira. Maelekitirodi a Platinamu amagwiritsidwa ntchito kulumikiza chinthu chokhudzidwa ndi mawaya omwe ali mu zingwe za waya za O2. Chingwe cha O2 chojambulira chimalumikizana ndi PCM kudzera pa netiweki yolamulira. Chojambulira cha O2 chimapatsa PCM chidziwitso cha nthawi yeniyeni pa kuchuluka kwa ma oxygen mu utsi wamafuta poyerekeza ndi zomwe zili mumlengalenga.

Kutulutsa utsi kuchokera ku injini kumakankhidwa kupyola mu utsi wambiri ndikudutsa mosinthira othandizira. Kenako amatha kudutsa pansi pa sensa ya O2. Mpweya wotulutsa mpweya umadutsa m'mabowo olowetsa mpweya m'nyumba zazitsulo komanso kudzera munjira yozindikira. Mpweya wakunja umalowetsedwa m'chipindacho pakati pa sensa kudzera pazingwe za waya. M'chipindacho, mpweya wozungulira umatenthedwa, ndikupangitsa kuti ma ayoni a oksijeni apange mavuto (amphamvu). Kusinthasintha pakati pa kuchuluka kwa mamolekyulu a oksijeni mumlengalenga (womwe umakhudzidwa ndi sensa ya O2) ndi kuchuluka kwa ma ayoni a oxygen pakutha kumapangitsa kusinthasintha kwamagetsi. Izi zimanjenjemera zimapangitsa ma ayoni a oxygen mkati mwa sensa ya O2 kuti abwere mofulumira komanso mobwerezabwereza kuchokera pa pulatinamu imodzi kupita kwina.

Kusintha kwamagetsi kumachitika pakamayendetsa mpweya wa ma oxygen pakati pa magawo a platinamu. PCM imazindikira kusintha kwamagetsi uku ngati kusintha kwa mpweya wa oxygen mumafuta otulutsa utsi. Zosinthazi zikuwonetsa ngati injini ikuyenda mopepuka (mafuta ochepa) kapena olemera (mafuta ochulukirapo). Mphamvu zotulutsa kuchokera ku sensa ya O2 ndizotsika pomwe pali mpweya wochulukirapo (wotere). Mphamvu yamagetsi ndiyokwera kwambiri mukakhala mpweya wocheperako (dziko lolemera). Izi zimagwiritsidwa ntchito ndi PCM, mwazinthu zina, kuwerengera njira zamafuta ndi nthawi yoyatsira.

PCM ikalowa mumalowo otsekedwa, ngati cholowa cha O2 chowerengera kumunsi kwa banki 2 chikuwonetsa mamolekyulu ochepa a oksijeni mu utsi, nambala ya P2099 idzasungidwa ndipo kuwala kosayenerera kungawunikire.

Kulimba ndi zizindikilo

Khodi ya P2099 imatanthauza kuti Bank 2 yakumunsi kwa O2 sensor yapeza kuti ili ndi vuto lotulutsa utsi. Kugwiritsa ntchito bwino mafuta kumatha kusokonekera ndipo nambala yake iyenera kuonedwa ngati yayikulu.

Zizindikiro za chikhombo cha P2099 zitha kuphatikizira izi:

• Kuchepetsa mafuta
• Kupanda magwiridwe antchito onse a injini
• Ma DTC ena okhudzana nawo atha kusungidwa
• Nyali ya injini yothandizira idzawala posachedwa

zifukwa

Zomwe zingayambitse kachidindo kameneka ndi monga:

• Bank 2 othandizira kusintha yolakwika.
• MAF yopunduka kapena kachipangizo kochepetsera mpweya.
• Cholakwika O2 sensor bank 2 / s
• Chowotcha chopindika, chosweka, chosweka, kapena chosadulidwa ndi / kapena zolumikizira
• Kutulutsa utsi kwa injini

Njira zowunikira ndikukonzanso

Malo oyambira nthawi zonse amayang'ana ma bulletins aukadaulo (TSB) pagalimoto yanu. Vuto lanu limatha kukhala vuto lodziwika bwino lokonzedwa ndi wopanga ndipo limatha kukupulumutsirani nthawi ndi ndalama mukamayesa kusaka.

Chojambulira matenda, digito volt ohmmeter (DVOM), ndi buku lothandizira zamagalimoto zitha kukhala zothandiza pakuzindikira nambala ya P2099. Deta Zonse (DIY) ndichonso gwero lalikulu lazithunzi zamagetsi zamagetsi ndi zina zogwiritsa ntchito.

Injini iyenera kuti ikuyenda bwino musanayese kudziwa nambala iyi. Khutitsani manambala, ma kachipangizo oyimitsa malo, kuchuluka kwa kuthamanga kwa mpweya, ndi ma code a MAF amayenera kuwunikiridwa asanayese kupeza nambala ya P2099.

Yambani poyang'ana mwakachetechete zingwe zolumikizira ndi zolumikizira. Ndi P2099, ndimayang'ana kwambiri ma harnesses omwe amayendetsedwa pafupi ndi mapaipi otentha otentha ndi ma manifolds, komanso omwe amayendetsedwa pafupi ndi m'mbali mwake (silinda mitu).

Lumikizani chojambulira ku doko lodziwitsa anthu ndikuchotsa ma DTC onse osungidwa ndikuwunditsa chimango. Lembani izi. Izi zitha kukhala zothandiza ngati zikhala zododometsa. Zizindikiro zakanthawi ndizovuta kuzizindikira.

Ngati P2099 ikukhazikikanso nthawi yomweyo, yambitsani injiniyo ndi kuilola kuti izitha kutentha. Zisiyeni zizingokhala (osalowerera ndale kapena zoyimikidwa). Gwiritsani ntchito sikani kuti muwone momwe Bank 2 O2 imathandizira. Onetsetsani chizindikiro cha sensa yakumunsi ya O2. Ngati injini ikuyenda bwino, zomwe zimachokera ku sensa ya O2 ziyenera kukhala pakati ndikukhala pamenepo.

DVOM itha kugwiritsidwa ntchito poyesa kukana kwa sensa ya O2 yomwe ikufunsidwa, ndi ma voliyumu ndi ma sign a nthaka yoyendera sensa ya O2. Chotsani owongolera omwe akugwiritsidwa ntchito musanayese kuyesa kuyeserera kwa dera ndi DVOM.

Zowonjezera zowonjezera:

• SENSOR yakomwekutsikira sikuyenera kugwira ntchito pafupipafupi ngati masensa kumtunda (PCM italowa modzitsekera). Ngati sensa yakumunsi ikupitilizabe kugwira ntchito nthawi zonse ngati sensa yakumtunda injini ikatentha ndipo PCM yalowa mumalowedwe otsekedwa, kukayikira chosintha cholakwika chothandizira.
• Pakufunika chosinthira chothandizira, lingalirani zinthu za OEM. Zosintha zosinthidwa kapena zosasinthika zomwe zimasinthidwa nthawi zambiri zimalephera mwachangu komanso mobwerezabwereza

ZINDIKIRANI. Izi zimaperekedwa kuti zidziwitse zokha. Sikuti tizigwiritsa ntchito ngati malingaliro okonzanso ndipo sitili ndi udindo pazomwe mungachite pagalimoto iliyonse. Zomwe zili patsamba lino ndizotetezedwa ndi zovomerezeka.
