P0043 Ƙananan nuna alama na kewayon sarrafawa na mai hura iskar oxygen (HO2S) B1S3

Bayanan Bayani na OBD-II

Ƙananan sigina a cikin da'irar sarrafa firikwensin oxygen (block 2, firikwensin 1)

Mene ne wannan yake nufi?

Wannan Diagnostic Trouble Code (DTC) lambar yabo ce ta watsawa, wanda ke nufin ya shafi motocin OBD-II da aka sanye da su ciki har da amma ba'a iyakance ga Nissan, Toyota, Mazda, Mitsubishi, Lexus, Infiniti, VW, da dai sauransu. Takamaiman matakan gyara na iya bambanta ta hanyar alama / samfur.

Sensor Oxygen Sensors (HO2S) abubuwan da PCM (Powertrain Control Module) ke amfani dashi don gano adadin iskar oxygen a cikin tsarin shayewa. Bank 1 Sensor 3 yana nufin firikwensin na uku akan banki 1. Bank 1 shine gefen injin da ke dauke da silinda #1 (injin layi suna da banki daya kacal). PCM tana amfani da bayanai daga Bank 1 #3 HO2S firikwensin da farko don saka idanu da ingancin mai mu'amalar catalytic. Babban ɓangaren wannan firikwensin shine kayan dumama.

PCM tana sarrafa wannan dumama don kawo firikwensin zuwa zafin aiki. Wannan yana ba injin damar shigar da rufaffiyar madauki da sauri kuma yana rage fitar da sanyin farawa. PCM na ci gaba da sa ido kan da'irorin dumama don ƙarancin ƙarfin lantarki ko, a wasu lokuta, har ma da amperages. Dangane da abin hawa, ana sarrafa injin firikwensin iskar oxygen ta hanyoyi biyu. Hanya ɗaya ita ce PCM ta sarrafa wutar lantarki kai tsaye zuwa ga hita, ko dai kai tsaye ko ta hanyar isar da iskar oxygen (HO2S), kuma ana ba da ƙasa daga wurin gama gari na abin hawa. Wata hanya kuma ita ce ƙarfin baturi 12V tare da fuse (B+) wanda ke ba da 12V ga mahaɗar wutar lantarki a duk lokacin da wuta ke kunne kuma direba yana sarrafa injin a cikin PCM wanda ke sarrafa gefen ƙasa na kewayen hita. .

Gano wanne kuke da shi yana da mahimmanci saboda PCM zai kunna hita a ƙarƙashin yanayi daban -daban. Idan PCM ta gano ƙarancin ƙarfin lantarki mara kyau akan da'irar hita, P0043 na iya saitawa.

Dalili mai yiwuwa na DTC P0043 na iya haɗawa da:

• Sensor #3 akan Oxygen Sensor Heater Bank 1 Ya Kasa
• Lalacewar jiki ga firikwensin iskar oxygen ya faru.
• Hanyar sarrafawa (ko samar da wutar lantarki, dangane da tsarin) an gajarta zuwa ƙasa
• Direban dumama na’urar firikwensin oxygen na PCM ya lalace

Matsaloli masu yuwu

Yi duba na gani na banki 1, HO3S 2 da kayan aikin wayoyi. Idan akwai wata lahani ga firikwensin ko kowace lahani ga wayoyi, gyara/maye gurbin yadda ake buƙata. Tabbatar cewa an kori wayoyi daga bututun shaye-shaye. Idan komai yana da kyau, cire HO1,3S akan banki 2 kuma tabbatar da cewa akwai 12 volts B+ tare da kashe injin (ko ƙasa yanzu, dangane da tsarin).

Bincika cewa da'irar sarrafa dumama (ƙasa) bata lalace ba. Idan haka ne, cire firikwensin O2 kuma duba shi don lalacewa. Idan kuna da damar yin amfani da ƙayyadaddun juriya, zaku iya amfani da ohmmeter don gwada juriya na abubuwan dumama. Juriya mara iyaka yana nuna karya a cikin hita. Sauya firikwensin oxygen idan ya cancanta.

Tattaunawar DTC mai dangantaka

• Kuskure P0146, P0043 akan Nissan Altima 08Sannu, nemi ɗan koyawa anan. Ya ɗauki motar ya maye gurbin firikwensin O2. Hasken ya ci gaba da ci. Na mayar da shi. An maye gurbin sabon firikwensin O2 tare da wata alama daban. Har yanzu hasken yana kunne. Wadanne matsaloli ne za su iya tsoma baki tare da rufe injin? Ana buƙatar duba motar ... 

Kuna buƙatar ƙarin taimako tare da lambar ku ta p0043?

Idan har yanzu kuna buƙatar taimako tare da DTC P0043, aika tambaya a cikin sharhin da ke ƙasa wannan labarin.

NOTE. An ba da wannan bayanin don dalilai na bayanai kawai. Ba a yi nufin amfani da shi azaman shawarar gyara ba kuma ba mu da alhakin duk wani mataki da za ku ɗauka a kan kowane abin hawa. Duk bayanan da ke wannan shafin ana kiyaye su ta haƙƙin mallaka.
