P2225 NOx Sensor Heater Sensor Circuit Intermittent Bank 2

Mapepala a OBD-II DTC

NOx Sensor Heater Sensor Circuit Intermittent Bank 2

Kodi izi zikutanthauzanji?

Imeneyi ndi nambala yovuta yoyeza matenda (DTC) ndipo imagwiritsidwa ntchito kwambiri pamagalimoto a OBD-II. Zogulitsa zamagalimoto zitha kuphatikizira, koma sizingokhala, Mercedes-Benz, Sprinter, VW, Audi, Ford, Dodge, Ram, Jeep, ndi zina zambiri.

Masensa a NOx (nitrogen oxide) amagwiritsidwa ntchito makamaka pakutulutsa mpweya mu injini za dizilo. Cholinga chawo chachikulu ndikuzindikira milingo ya NOx yotuluka mu mpweya wotulutsa mpweya pambuyo pa kuyaka muchipinda choyaka. Kenako dongosololi limawapanga pogwiritsa ntchito njira zosiyanasiyana. Chifukwa cha zovuta zogwirira ntchito za masensa awa, amapangidwa ndi kuphatikiza kwa ceramic ndi mtundu wina wa zirconia.

Chimodzi mwazovuta za mpweya wa NOx m'mlengalenga ndikuti nthawi zina zimatha kuyambitsa utsi ndi / kapena mvula yamchere. Kulephera kuwongolera mokwanira ndikuwongolera masitepe a NOx kumabweretsa zovuta pamlengalenga pomwe tikupuma. ECM (Engine Control Module) imayang'anitsitsa masensa a NOx kuti zitsimikizire kuchuluka kwa mpweya mumoto wamagalimoto anu.

Gawo lowongolera injini (ECM) limatha kuwerengera mpweya wa nitrogen oxide ndi nitrogen dioxide (NOx) pogwiritsa ntchito deta yomwe idalandilidwa kuchokera kumtunda wagalimoto ndi masensa a okosijeni otsika kuphatikiza ndi kuwerenga kwa sensa ya NOx. ECM imachita izi kuwongolera milingo ya NOx yotuluka mumchira pazifukwa zotulutsa chilengedwe. Bank 2 yotchulidwa m'ma code ovuta ndi chipika cha injini chomwe chilibe silinda # 1.

P2225 ndi code yomwe ikufotokozedwa ngati NOx Sensor Heater Sensor Circuit Intermittent Bank 2, zomwe zikutanthauza kuti ECM yapeza kusagwirizana pakuchita kwathunthu kwa NOx Sensor Heater Sensor Circuit.

Ma injini a dizilo makamaka amatulutsa kutentha kwakukulu, choncho onetsetsani kuti makinawo aziziziritsa musanagwiritse ntchito zida zilizonse zotulutsa utsi.

Chitsanzo cha sensa ya NOx (pankhani iyi yamagalimoto a GM):

Kodi kuuma kwa DTC kumeneku ndi kotani?

Ngati ma DTCs anyalanyazidwa ndipo palibe kanthu kakonzedwe komwe kachitidwa, zitha kubweretsa kusinthasintha kwa othandizira. Kusiya zizindikilo ndi zomwe zimayambitsa ma DTCwa osasankhidwa kumatha kubweretsa zovuta zina pagalimoto yanu, monga kuyimitsa pafupipafupi komanso kuchepetsa mafuta. Mukawona zina mwazomwe zingatchulidwe pamndandanda uli pansipa, tikulimbikitsidwa kuti mukayang'ane ndi katswiri.

Kodi zina mwazizindikiro za code ndi ziti?

Zizindikiro za kachilombo ka P2225 zitha kuphatikizira izi:

• Kuyima kwakanthawi
• Injini siyamba ikatentha
• Kutsika kwa magwiridwe antchito a injini
• Pakhoza kukhala kwake ndi / kapena kunjenjemera mukamathamanga.
• Injini imatha kuthamanga kapena kukhala yolemera pagombe # 2.

Kodi zina mwazomwe zimayambitsa codezi ndi ziti?

Zifukwa za code iyi ya P2225 NOx itha kuphatikizira:

• Chothandizira othandizira chosalongosoka
• Mafuta osakaniza olakwika
• Cholakwika chozizira chozizira
• Zobwezedwa mpweya kachipangizo wosweka
• Pali zovuta ndi sensa yotulutsa misa
• Mafuta jekeseni mbali zosalongosoka
• Wowongolera wamagetsi wasweka
• Panali zolakwika
• Pali zotulutsa kuchokera pamitundu ingapo ya utsi, payipi ya chikwapu, mapaipi, kapena gawo lina la dongosolo la utsi.
• Masensa osweka a oxygen

Kodi ndi njira ziti zodziwira ndikusokoneza P2225?

Gawo loyamba pamavuto amtundu uliwonse ndikuwunikanso za Technical Service Bulletins (TSB) pamavuto odziwika ndi galimoto inayake.

Njira zodziwitsira zapamwamba zimangokhala zododometsa kwambiri zamagalimoto ndipo zimatha kufunikira zida zoyenerera komanso chidziwitso kuti zichitike molondola. Timalongosola njira zomwe zili pansipa, koma tchulani buku lanu lokonzekera galimoto / mapangidwe / mtundu / kapangidwe kake ka mayendedwe amtundu wa galimoto yanu.

Gawo loyambira # 1

Gawo loyamba liyenera kukhala lochotsa ma code ndikuwunikiranso galimotoyo. Ngati palibe ma DTCs (Matenda Othandizira Kuzindikira) omwe amapezeka nthawi yomweyo, yesani kuyeserera kwakutali ndikuyima kangapo kuti muwone ngati awonekeranso. Ngati ECM (Engine Control Module) ikayambitsanso nambala imodzi yokha, pitilizani kudziwa za kachidindo kameneka.

Gawo loyambira # 2

Kenako muyenera kuyang'ana utsi kuti mutsike. Mwaye wakuda wozungulira ming'alu ndi / kapena ma gaskets amachitidwe ndi chizindikiro chabwino cha kutayikira. Izi ziyenera kuchitidwa moyenera, nthawi zambiri mpweya wotulutsa mpweya ndi wosavuta kusintha. Kutulutsa kosindikizidwa kwathunthu ndi gawo lofunikira la masensa omwe akukhudzidwa ndi makina anu otulutsa mpweya.

Gawo loyambira # 3

Ndi thermometer ya infrared, mutha kuwunika kutentha kwa mpweya wotulutsa utsi usanachitike komanso mutatha kusintha kwa othandizira. Muyeneranso kuyerekeza zotsatira ndi zomwe wopanga akuchita, chifukwa chake onani buku lanu lazomwe mungachite.

Gawo loyambira # 4

Ngati kutentha kwa chosinthira chothandizira kuli mkati mwakulinganiza, samalani makina amagetsi ogwirizana ndi masensawa. Yambani ndi zingwe zama waya komanso cholumikizira masensa a banki a NOX. Konzani mawaya owonongeka powotcha malumikizowo ndikuwachepetsa. Onaninso masensa a oxygen omwe amagwiritsidwa ntchito ku Bank 2 kuti awonongeke kuti sanawonongeke, zomwe zitha kusintha kusintha kwa kuwerenga kwa NOx. Konzani cholumikizira chilichonse chomwe sichipanga zolumikizana zokwanira kapena sichikiyika bwino.

Nkhaniyi ndi yongofuna kudziwa zambiri komanso zidziwitso zaumisili ndi zolembera zamagalimoto anu nthawi zonse ziyenera kukhala patsogolo.

Zokambirana zokhudzana ndi DTC

• Pakadali pano palibe mitu yofananira m'mabwalo athu. Tumizani mutu watsopano pamsonkhano tsopano.

Mukufuna thandizo lina ndi code P2225?

Ngati mukufunabe thandizo ndi DTC P2225, 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.
