P2198 O2 Sensor Signal Code Bias / Stuck Rich (Bank 2 SENSOR 1)

P2198 O2 Sensor Signal Code Bias / Stuck Rich (Bank 2 SENSOR 1)

Mapepala a OBD-II DTC

Chizindikiro cha sensor cha A / F O2 chotsalira / chokhazikika munthawi yopindulitsa (block 2, sensor 1)

Kodi izi zikutanthauzanji?

Nambala iyi ndi nambala yofalitsira. Imawerengedwa kuti ndiyaponseponse momwe imagwirira ntchito popanga mitundu yonse yamagalimoto (1996 ndi atsopano), ngakhale njira zowongolera zingasiyane pang'ono kutengera mtunduwo.

Pamagalimoto ena ngati Toyota, izi zimatanthawuza masensa a A / F, masensa owerengera mpweya / mafuta. M'malo mwake, awa ndi masensa okhudzidwa kwambiri a oxygen.

Modulerain control module (PCM) imayang'anira kuchuluka kwa mpweya / mafuta pogwiritsa ntchito masensa a oxygen (O2) ndikuyesera kukhala ndi chiyerekezo cha mpweya / mafuta wa 14.7: 1 kudzera pamafuta. Chojambulira cha Oxygen A / F chimapereka kuwerengera kwamagetsi komwe PCM imagwiritsa ntchito. DTC iyi imayika pomwe kuchuluka kwa mpweya / mafuta kumawerengedwa ndi PCM kuli kolemera (mafuta ochulukirapo osakanikirana) ndipo amasokonekera kwambiri kuchokera pa 14.7: 1 kotero kuti PCM singathenso kuwongolera.

Khodi iyi imatanthawuza makamaka sensor pakati pa injini ndi chosinthira chothandizira (osati kumbuyo kwake). Bank #2 ndi mbali ya injini yomwe ilibe silinda #1.

Chidziwitso: DTC iyi ndiyofanana kwambiri ndi P2195, P2196, P2197. Ngati muli ndi ma DTC angapo, nthawi zonse muziwongolera momwe amawonekera.

Zizindikiro

Pa DTC iyi, Nyali Yoyang'anira Chizindikiro (MIL) idzawala. Pakhoza kukhala zizindikilo zina, monga kuchuluka kwa mafuta.

zifukwa

Zomwe zingayambitse kachidindo ka P2198 ndi izi:

• Chosavomerezeka cha oxygen (O2) kapena chiŵerengero cha A / F kapena chotenthetsera sensa
• Tsegulani kapena zazifupi mu dera la sensor la O2 (wiring, harness)
• Kuthamanga kwa mafuta kapena vuto la jakisoni wamafuta
• PCM yolakwika
• Kulowetsa mpweya kapena zingalowe m'malo mwa injini
• Ma injini operewera
• Mafuta kuthamanga kwambiri kapena otsika kwambiri
• Kutayikira / kulephera kwa dongosolo la PCV
• A / F kachipangizo kulandirana zosalongosoka
• Kulephera kwa MAF sensor
• Chojambula cha ECT chosagwira bwino
• Kuletsa kudya
• Mafuta kuthamanga kwambiri
• Mafuta kukanika kachipangizo wonongeka
• Mafuta mavuto kuthamanga yolephera
• Chonde dziwani kuti pamagalimoto ena omwe asinthidwa, nambala iyi imatha kubwera chifukwa cha zosintha (mwachitsanzo, dongosolo lotulutsa, manifolds, ndi zina zambiri).

Njira zowunikira ndi njira zothetsera mavuto

Gwiritsani ntchito chida chojambulira kuti muwerenge kuwerenga kwa sensa ndikuwunika mitengo yaying'ono komanso yayitali yayitali ndi sensa ya O2 kapena kuwerengera kwa chiwonetsero cha mafuta. Komanso, yang'anani pazithunzi zoyimitsa kuti muwone momwe zakhalira mukakhazikitsa code. Izi ziyenera kuthandizira kudziwa ngati sensa ya O2 AF ikugwira bwino ntchito. Yerekezerani ndi zomwe opanga amapanga.

Ngati mulibe chida chofufuzira, mutha kugwiritsa ntchito multimeter ndikuyang'ana zikhomo pa cholumikizira cha O2 sensor. Fufuzani zazifupi pansi, zopanda mphamvu, zotseguka, ndi zina. Yerekezerani magwiridwe antchito ndi mafotokozedwe aopanga.

Yang'anani mwamphamvu zingwe zolumikizira ndi zolumikizira zomwe zikupita ku sensa, yang'anani zolumikizira zosasunthika, ma scuffs / scuffs, mawaya osungunuka, ndi zina. Konzani ngati kuli kofunikira.

Yang'anani m'mizere yopumira. Muthanso kuyang'anitsitsa kutuluka kolowera pogwiritsa ntchito gasi wa propane kapena chotsukira mafuta pamphepete mwa ma injini pomwe injini ikuyenda, ngati rpm isintha, mwina mwapeza kutayikira. Samalani kwambiri pochita izi ndipo sungani chozimitsira moto pakagwa vuto. Ngati vutoli latsimikizika kuti limangotulutsa, kungakhale kwanzeru kusinthitsa mizere yonse yazitsulo ngati atakalamba, atakhala olimba, ndi zina zambiri.

Gwiritsani ntchito digito volt ohm mita (DVOM) kuti muwone ngati masensa ena omwe atchulidwa akugwira ntchito bwino, monga MAF, IAT.

Yesani kuyesa kuyesa mafuta, yang'anani kuwerenga motsutsana ndi zomwe wopanga adachita.

Ngati muli ndi bajeti yolimba ndipo muli ndi injini yokhala ndi banki zoposa imodzi ndipo banki imodzi yokha ndiye ili ndi vuto, mutha kusinthana ndi gauge kuchokera ku banki kupita ku ina, kuchotsa nambalayo, ndikuwona ngati nambala yake ikulemekezedwa. kupita tsidya lina. Izi zikuwonetsa kuti sensa / chowotcha chokha ndicholakwika.

Fufuzani galimoto yanu yaposachedwa ya Technical Service Bulletins (TSB), nthawi zina PCM ikhoza kusinthidwa kuti ikonze izi (ngakhale iyi si yankho wamba). Ma TSB angafunenso m'malo mwa sensa.

Mukamachotsa masensa a oxygen / AF, onetsetsani kuti mukugwiritsa ntchito zabwino. Nthawi zambiri, masensa a gulu lachitatu amakhala otsika ndipo sagwira ntchito momwe amayembekezera. Tikukulimbikitsani kuti mugwiritse ntchito m'malo mwaopanga zida zoyambirirazo.
