Ikhodi ye-P2196 O2 yeSensor Signal Code Bias / Stuck Rich (Ibhange 1 Inzwa 1)

Ikhodi Yenkinga ye-OBD-II - P2196 - Ishidi Ledatha

Isignali yenzwa ye-A / F O2 ichemile / ibhajwe esimweni esicebile (block 1, sensor 1)

Isho ukuthini ikhodi yenkinga P2196?

Le khodi iyikhodi yokudlulisela ejwayelekile. Kubhekwa njengendawo yonke njengoba kusebenza kukho konke ukwakheka namamodeli ezimoto (1996 nangaphezulu), yize izinyathelo ezithile zokulungisa zingahluka kancane ngokuya ngemodeli.

Kwezinye izimoto ezifana neToyota, empeleni lokhu kubhekisa kuzinzwa ze-A / F, izinzwa zomoya / kaphethiloli. Eqinisweni, lezi yizinhlobo ezibucayi kakhulu zezinzwa ze-oxygen.

Imodyuli yokulawula i-powertrain (PCM) iqapha isilinganiso sokukhipha umoya / uphethiloli isebenzisa izinzwa ze-oxygen (O2) futhi izama ukugcina isilinganiso esijwayelekile somoya / sephethiloli esingu-14.7: 1 ngohlelo lwamafutha. Inzwa ye-Oxygen A / F inikeza ukufundwa kwamandla okusetshenziswa yi-PCM. Le DTC ibeka lapho isilinganiso somoya / sephethiloli esifundwa yi-PCM sisuka ku-14.7: 1 ukuze i-PCM ingasakwazi ukukulungisa.

Le khodi isho ngokuqondile inzwa ephakathi kwenjini nesiguquli se-catalytic (hhayi esingemuva kwayo). Ibhange #1 liwuhlangothi lwenjini equkethe isilinda #1.

Qaphela: Le DTC icishe ifane ne-P2195, P2197, P2198. Uma unama-DTC amaningi, hlala uwalungisa ngokulandelana kwawo.

Izimpawu

Kule DTC, iLamp Indicator Indicator (MIL) izokhanyisa. Kungaba nezinye izimpawu futhi.

Izimbangela zephutha З2196

Le khodi isethiwe ngenxa yokuthi uphethiloli omningi ujovwa egumbini elivuthayo. Lokhu kungadalwa ngamashwa ahlukahlukene.

Isilawuli sikaphethiloli esiphukile i-diaphragm ECT (izinga lokushisa elipholile lenjini) inzwa yokucindezela kukaphethiloli ephezulu Izintambo ezilimele eziya ku-ECT Zivale umjovo kaphethiloli ovulekile noma izijovo ze-PCM (Powertrain Control Module)

Izimbangela ezingaba khona zekhodi ye-P2196 zifaka:

• Inzwa engasebenzi kahle ye-oxygen (O2) noma isilinganiso se-A / F noma i-heater yenzwa
• Isifunda esivulekile noma esifushane kusifunda se-O2 sensor (wiring, harness)
• Ukucindezela kwe-Fuel noma inkinga ye-injector injector
• I-PCM enamaphutha
• Ukungenisa umoya noma ukuvuza komshini enjinini
• Ama-injectors kagesi angenaphutha
• Umfutho we-Fuel uphezulu kakhulu noma uphansi kakhulu
• Ukuvuza / ukungasebenzi kahle kohlelo lwe-PCV
• Ukudluliswa kwenzwa ye-A / F kunesici
• Ukungasebenzi kahle kwenzwa ye-MAF
• Ukungasebenzi kahle kwenzwa ye-ECT
• Ukuvinjelwa kokungeniswa komoya
• Umfutho we-Fuel uphezulu kakhulu
• Ukungasebenzi kahle kwenzwa yokucindezela kwe-Fuel
• Ukungasebenzi kahle kwesilawuli se-Fuel
• Uyacelwa ukuthi uqaphele ukuthi kwezinye izimoto eziguquliwe, le khodi ingadalwa izinguquko (isb. Uhlelo lokukhipha, ama-manifolds, njll.).

Izinyathelo zokuxilonga kanye nezixazululo ezingaba khona

Sebenzisa ithuluzi lokuskena ukuthola ukufundwa kwenzwa futhi ubheke amanani wesikhashana wesikhathi esifushane nowesikhathi eside kanye nenzwa ye-O2 noma ukufundwa kwenzwa yesilinganiso sophethiloli womoya. Futhi, bheka idatha yozimele ukuze ubone izimo ngenkathi usetha ikhodi. Lokhu kufanele kusize ukunquma ukuthi inzwa ye-O2 AF isebenza kahle. Qhathanisa namanani wabakhiqizi.

Uma ungenakho ukufinyelela kuthuluzi lokuskena, ungasebenzisa i-multimeter bese uhlola izikhonkwane kusixhumi se-w2 sensor wiring. Bheka okufishane phansi, okufushane ngamandla, isekethe evulekile, njll. Qhathanisa ukusebenza nezincazelo zomkhiqizi.

Hlola ngokubonakalayo izintambo nezixhumi eziholela enzwa, hlola izixhumi ezikhululekile, izigaxa zezintambo / izikhafu, izintambo ezincibilikile, njll. Lungisa lapho kudingeka.

Hlola ngokubuka imigqa yomshini. Ungahlola nokuvuza okuphuma ngaphandle usebenzisa i-propane gas noma i-carburetor cleaner eduze kwamapayipi lapho injini isebenza, uma i-rpm ishintsha, kungenzeka ukuthi uthole ukuvuza. Qaphela kakhulu lapho wenza lokhu futhi ugcine isicishamlilo sisebenziseka uma kwenzeka okuthile kungahambi kahle. Uma inkinga ithathwa njengokuvuza kwesikhala, kungaba ukuhlakanipha ukufaka esikhundleni sayo yonke imigqa yokuhlanza uma ikhula, iba namandla, njll.

Sebenzisa imitha ye-digital volt ohm (DVOM) ukubheka ukuthi ingabe ezinye izinzwa ezishiwo zisebenza kahle yini, njenge-MAF, IAT.

Yenza ukuhlolwa kwengcindezi kaphethiloli, hlola ukufundwa ngokuhambisana nemininingwane yomkhiqizi.

Uma unesabelomali esiqinile futhi unenjini enebhange elingaphezu kwelilodwa kuphela futhi yibhange elilodwa kuphela eliyinkinga, ungashintsha igeji usuke kwelinye ibhange uye kwelinye, usule ikhodi, bese ubona ukuthi ikhodi iyahlonishwa yini. kolunye uhlangothi. Lokhu kukhombisa ukuthi inzwa / i-heater uqobo ayilungile.

Bheka ama-Bulletins (TSB) akamuva wemoto yakho, kokunye i-PCM ingalinganiselwa ukulungisa lokhu (yize lesi kungesona isixazululo esivamile). Ama-TSB angahle adinge ukushintshwa kwenzwa.

Lapho ushintsha izinzwa ze-oxygen / AF, qiniseka ukuthi usebenzisa ezekhwalithi. Ezimweni eziningi, izinzwa ezivela eceleni zinekhwalithi ephansi futhi azisebenzi njengoba bekulindelekile. Sincoma ngokuqinile ukusebenzisa indawo yomakhi wemishini yokuqala.

Amaphutha Avamile Lapho Uhlonza Ikhodi P2196

Iphutha elivame kakhulu ukufaka inzwa ye-O2 ngemva kokubheka ikhodi nokudebeselela ukwenza noma yiziphi izivivinyo ukuze kuqinisekiswe ukuthi i-O2 iyiphutha ngempela. Konke ukwehluleka okubalwe ngezansi kuzodala lesi simo ngenzwa ye-O2 futhi isikhathi kufanele sisetshenziswe ukuhlukanisa inkinga.

Ngaphezu kokushintsha inzwa ye-O2 ngokushesha, inkinga efanayo iyenzeka lapho uchwepheshe etolika idatha yesithwebuli ngokushesha kakhulu. Ngokuvamile lokhu kuzoba ukuxilongwa okulula. Kangangoba ukufaka esikhundleni sezingxenye ezivame ukwehluleka kwezinye izimoto kuzoba yinto evamile. Zonke izimoto zinalokhu ochwepheshe abakubiza ngokuthi ukungasebenzi kahle kwephethini. Uma siqala ukubona lawa maphethini, kulula ukukhohlwa ukuthi amanye amaphutha angadala ikhodi enjalo. Uma lokhu kwenzeka, isenzo esisheshayo siholela ekushintshweni kwezingxenye ezingalungile, okuholela ekwenyukeni kwezindleko zokulungisa noma ukuchitha isikhathi kuchwepheshe.

Ibucayi kangakanani ikhodi ye-P2196?

Into engathi sína kakhulu engenzeka ngenxa yesimo sokusebenza esicebile ukuthi kungenzeka ukuthi isiguquli se-catalytic sibambe umlilo. Akuvamile, kodwa kungenzeka. Ukwengeza uphethiloli owengeziwe kusiguquli se-catalytic kufana nokuphonsa izinkuni emlilweni. Uma lesi simo sikhona, ukukhanya kwakho kwe-Check Engine kuzokhanya ngokushesha. Uma ubuka ukukhanya kwe-Check Engine kuphazima, uzibeka engcupheni yomlilo wokuguqula i-catalytic.

Uma ukukhanya kwakho kwe-Check Engine kukhanya ngaso sonke isikhathi futhi kungacwayizi, khona-ke le khodi ibucayi njengokuthi imoto yakho isebenza kabi kangakanani. Ezimweni ezimbi kakhulu, lokhu kuzosebenza ngokungenangqondo futhi ngokusobala. Okungcono kakhulu, uzolahlekelwa ukonga kukaphethiloli.

Yiziphi izilungiso ezingalungisa ikhodi P2196?

• ukushintshwa kwesilawuli somfutho kaphethiloli
• Ukushintshwa Kwenzwa ye-Mass Air Flow (MAF).
• Ukushintsha inzwa ye-ECT (izinga lokushisa elipholile uketshezi lwenjini)
• Ukulungiswa kwezintambo ezilimele ku-ECT
• Shintshanisa umjovo kaphethiloli ovuzayo noma obambekile noma izijovo.
• Ukushintshwa kwenzwa ye-O2
• Shuna. Faka esikhundleni inhlansi plug , izintambo ze-spark plug, i-cap ne-rotor , i-coil block noma izintambo zokuthungela.

Amazwana engeziwe okufanele acatshangelwe mayelana nekhodi P2196

Iphutha elivamile ukucabanga ukuthi ingxube ecebile iwumphumela wokujova uphethiloli omningi enjinini. Ukucabanga okunembe kakhudlwana ukuthi kunophethiloli omningi uma uhlobene nomoya. Ngakho igama elithi air-fuel ratio. Noma nini lapho uxilonga ikhodi enjalo, kubaluleke kakhulu ukuthi uhlale ucabangela lokhu. Kuvame kakhulu ukuba nengxenye embi yokuthungela noma ingabi nayo inhlansi kusilinda, kodwa i-PCM isayala uphethiloli kumjovo. Lokhu kuzodala ukuthi uphethiloli ongashisiwe ungene epayipini le-exhaust. Manje isilinganiso phakathi kwe-oksijeni nophethiloli ohlelweni lokukhipha umoya sishintshile futhi i-O2 ihumusha lokhu njenge-oxygen encane, i-PCM ehumusha njengophethiloli owengeziwe. Uma inzwa ye-O2 ithola i-oksijini eningi ekukhishweni, i-PCM ihumusha lokhu njengophethiloli onganele noma uphethiloli omncane.

Udinga usizo olwengeziwe ngekhodi le-p2196?

Uma usadinga usizo nge-DTC P2196, 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.
