Ikhodi ye-P2198 O2 yeSensor Signal Code Bias / Stuck Rich (Ibhange 2 Inzwa 1)

Ikhodi ye-P2198 O2 yeSensor Signal Code Bias / Stuck Rich (Ibhange 2 Inzwa 1)

Idatha ye-OBD-II DTC

Isignali yenzwa ye-A / F O2 ichemile / ibhajwe esimweni esicebile (block 2, sensor 1)

Kusho ukuthini lokhu?

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 somoya / sephethiloli sisebenzisa 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 sicebile (uphethiloli omningi kakhulu enhlanganisweni) futhi iphambuka kakhulu kusuka ku-14.7: 1 kangangokuba i-PCM ingasakwazi ukukulungisa.

Le khodi isho ngokuqondile inzwa ephakathi kwenjini nesiguquli se-catalytic (hhayi esingemuva kwayo). Ibhange #2 liwuhlangothi lwenjini engenawo isilinda #1.

Qaphela: Le DTC icishe ifane ne-P2195, P2196, P2197. Uma unama-DTC amaningi, hlala uwalungisa ngokulandelana kwawo.

izimpawu

Kule DTC, iLamp Indicator Indicator (MIL) izokhanyisa. Kungase kube nezinye izimpawu, njengokunyuka kokusebenzisa uphethiloli.

izizathu

Izimbangela ezingaba khona zekhodi ye-P2198 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.
