P2274 O2 Sensor Signal Bias / Stuck Lean Bank 1 SENSOR 3
Mapepala a OBD-II DTC
O2 Sensor Signal Offset / Stuck Lean Bank 1 SENSOR 3
Kodi izi zikutanthauzanji?
Iyi ndi nambala yotumizira ma generic zomwe zikutanthauza kuti imagwira ntchito pamagalimoto onse a OBD-II kuyambira 1996 kupita mtsogolo. Mitundu yamagalimoto ingaphatikizepo koma osati ku Mazda, Ford, VW, Mercedes Benz, ndi zina zambiri. Komabe, njira zothetsera mavuto zitha kusiyana kutengera galimoto.
Chizindikiro Chovutikira Chodziwitsa (DTC) P2274 chimagwira ku Postcatalytic Converter O2 (oxygen) sensor pa block # 1, sensor # 3. Chojambulira ichi chogwiritsa ntchito paka chimagwiritsidwa ntchito kuwunika momwe chosinthira chothandizira chilili. Ntchito yosinthira ndikuchepetsa utsi wotulutsa. DTC iyi imayika PCM itazindikira chizindikirocho kuchokera ku sensa ya O2 ngati yopindika kapena yopendekera molakwika.
DTC P2274 imatanthawuza sensa yachiwiri yakumunsi (pambuyo pa chosinthira chachiwiri chothandizira), sensor #3 pa banki #1. Bank #1 ndi mbali ya injini yomwe ili ndi silinda #1.
Nambala iyi imakuwuzani kuti chizindikirocho chomwe chimaperekedwa ndi sensa inayake yamtunduwu chimakhala chosakanikirana (chomwe chimatanthauza kuti pali mpweya wochuluka mu utsi).
Chitsanzo mpweya kachipangizo O2: 
Zizindikiro
Mwayi wake, simudzawona zovuta zilizonse popeza izi sizowunikira # 1. Mudzawona kuti Kuwala kwa Chizindikiro Chosagwira (MIL) kumabwera. Komabe, nthawi zina, injini imatha kugwira ntchito mosadukiza.
Zotheka
Zifukwa za DTC iyi zitha kuphatikiza:
- Utsi mpweya kutayikira pafupi kachipangizo O2
- Choyipa kapena cholakwika HO2S2 sensor (sensa 3)
- HO2S2 Vuto La Kulumikizana / Dera
- Kukhazikitsa kwaulere sensa ya HO2S2
- Mafuta olakwika
- Woperewera wamafuta wamafuta
- Zoziziritsa injini
- Cholakwika purge valavu solenoid
- PCM yatha
Njira zowunikira ndikukonzanso
Yang'anirani zingwe zolumikizira ndi zolumikizira zazingwe, zingwe zopota / zotchinga / zopindika, zikhomo zopindika / zotayirira, mawilo owotcha ndi / kapena owoloka. Konzani kapena sinthanitsani pakufunika.
Fufuzani kutuluka kwa utsi ndikukonzekera ngati kuli kofunikira.
Pogwiritsa ntchito digito volt ohm mita (DVOM) yoyikidwira ma ohms, yesani zolumikizira zingwe kuti musakanidwe. Yerekezerani ndi mafotokozedwe opanga. Sinthanitsani kapena kukonza pakufunika kutero.
Ngati mutha kugwiritsa ntchito chida chofufutira, gwiritsani ntchito kuwunika momwe amawerengera masensa monga PCM (injini yomwe imagwira ntchito nthawi yanthawi yotentha yotsekedwa). Kumbuyo kwa mpweya wotentha wa oxygen (HO2S) nthawi zambiri kumawona kusinthasintha kwamagetsi pakati pa 0 ndi 1 volt, pa DTC iyi mwina mudzawona magetsi akukakamira pa 0 V. Kusinthasintha injini kuyenera kuchititsa kuti sensa yamagetsi isinthe (kuyankha).
Zokonzekera zodziwika bwino za DTC iyi ndikutulutsa mpweya, vuto ndi sensa / wiring wiring, kapena sensa yokha. Ngati mukusintha kachipangizo kanu ka O2, gulani chojambula cha OEM (dzina lachidziwitso) kuti mupeze zotsatira zabwino.
Ngati mukuchotsa HO2S, yang'anani kuipitsidwa ndi mafuta, mafuta a injini, ndi kozizira.
Malingaliro ena othetsera mavuto: Gwiritsani ntchito woyesa mafuta, yang'anani kuthamanga kwa mafuta pa Schrader valve pa njanji yamafuta. Yerekezerani ndi malingaliro a wopanga. Yendani chotsukira cha solenoid valve. Yenderani opangira mafuta. Yang'anani magawo ozizira kuti atuluke.
Zokambirana zokhudzana ndi DTC
- Pakadali pano palibe mitu yofananira m'mabwalo athu. Tumizani mutu watsopano pamsonkhano tsopano.
Mukufuna thandizo lina ndi code P2274?
Ngati mukufunabe thandizo ndi DTC P2274, lembani funso mu ndemanga pansipa pamutuwu.
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.
