I-P2274 O2 Sensor Signal Bias / Stuck Lean Bank 1 Inzwa 3
Idatha ye-OBD-II DTC
I-O2 Sensor Signal Offset / Stuck Lean Bank 1 Inzwa 3
Kusho ukuthini lokhu?
Le ikhodi yokudlulisela ejwayelekile okusho ukuthi isebenza kuzo zonke izimoto ze-OBD-II kusuka ngo-1996 kuye phambili. Imikhiqizo yezimoto ingafaka kepha ayikhawulelwe kuMazda, Ford, VW, Mercedes Benz, njll. Nokho, izinyathelo ezithile zokuxazulula inkinga zingahluka ngokuya ngemoto.
Le Khodi Yezinkinga Zokuxilonga (i-DTC) i-P2274 isebenza kwinzwa yePostcatalytic Converter O2 (oxygen) ku-block # 1, inzwa # 3. Le nzwa yokulandela ikati isetshenziselwa ukuqapha ukusebenza kahle kwesiguquli se-catalytic. Umsebenzi wesiguquli ukunciphisa ukukhipha ukukhipha. Le DTC ibeka lapho i-PCM ithola isignali evela kunzwa ye-O2 njengoba inamathele incikile noma incike kabi.
I-DTC P2274 isho inzwa yesibili ezansi nomfula (ngemuva kwesiguquli sesibili se-catalytic), inzwa #3 ebhange #1. Ibhange #1 liwuhlangothi lwenjini equkethe isilinda #1.
Le khodi ikutshela ngokuyisisekelo ukuthi isignali enikezwe inzwa ethile ye-oyxgen ibhajwe enhlanganisweni enciphile (okusho ukuthi kunomoya omningi kakhulu kusisi).
Inzwa ye-oxygen ejwayelekile O2: 
izimpawu
Amathuba ukuthi, ngeke uqaphele noma yiziphi izinkinga zokuphatha njengoba lokhu kungeyona inzwa # 1. Uzobona ukuthi i-Malfunction Indicator Light (MIL) iza. Kodwa-ke, kwezinye izimo, injini ingasebenza ngezikhathi ezithile.
Izizathu ezingenzeka
Izizathu zale DTC zingafaka:
- Khipha ukuvuza kwegesi eduze kwenzwa ye-O2
- Inzwa ye-HO2S2 engcolile noma enesici (inzwa 3)
- Inkinga Yezintambo / Yesekethe ye-HO2S2
- Ukufakwa kwamahhala kwenzwa ye-HO2S2
- Ukucindezelwa kukaphethiloli okungalungile
- Umjovo wephethiloli onamaphutha
- Isipholisi senjini esivuzayo
- Iphutha le-purge solenoid valve
- I-PCM ayisebenzi
Izinqubo zokuxilonga nokulungisa
Hlola ngokubonakalayo izintambo nezixhumi zokubona ukugqwala, izintambo ezixotshiwe / ezixutshiwe / ezikhonjiwe, izikhonkwane zokugoba / zokuxega, izintambo ezishisiwe kanye / noma eziwele. Lungisa noma shintsha njengoba kudingeka.
Bheka ukuvuza kokukhipha nokulungisa uma kudingeka.
Usebenzisa imitha ye-digital volt ohm (DVOM) esethwe kuma-ohms, hlola izixhumi ze-harness ukumelana nayo. Qhathanisa nezincazelo zomkhiqizi. Faka esikhundleni noma ulungise lapho kudingeka.
Uma ukwazi ukufinyelela kuthuluzi lokuskena eliphambili, lisebenzise ukuqapha ukufundwa kwenzwa njengoba kubonwe yi-PCM (injini esebenza ngokushisa okujwayelekile kokusebenza kumodi ye-loop evaliwe). Inzwa yangemuva evuthayo ye-oxygen (HO2S) ivame ukubona ukwehla kwamandla kagesi phakathi kuka-0 no-1 volt, kule DTC cishe uzobona ukuthi i-voltage ibambeke ku-0 V. Ukushintshanisa injini kufanele kubangele ukuthi i-sensor yamandla ishintshe (isabele).
Ukulungiswa okuvame kakhulu kwale DTC ukuvuza komoya, inkinga nge-sensor / wiring wiring, noma inzwa uqobo. Uma ushintsha inzwa yakho ye-O2, thenga inzwa ye-OEM (igama lomkhiqizo) ukuthola imiphumela emihle.
Uma ususa ama-HO2S, hlola ukungcoliswa kukaphethiloli, uwoyela wenjini nasesipholiseni.
Eminye imibono yokuxazulula inkinga: Sebenzisa umhloli wokucindezela uphethiloli, hlola ingcindezi kaphethiloli ku-valve yeSchrader kujantshi kaphethiloli. Qhathanisa nemininingwane yomkhiqizi. Hlola i-purge solenoid valve. Hlola izijobelelo zikaphethiloli. Hlola izindawo ezipholile zokuvuza.
Izingxoxo ezihlobene ze-DTC
- Okwamanje azikho izihloko ezihlobene ezinkundleni zethu. Thumela isihloko esisha esithangamini manje.
Udinga usizo olwengeziwe ngekhodi engu-P2274?
Uma usadinga usizo nge-DTC P2274, thumela umbuzo kumazwana angezansi kwalesi sihloko.
QAPHELA. Lolu lwazi lunikezwa ngenhloso yokwaziswa kuphela. Akuhloselwe ukuthi isetshenziswe njengesincomo sokulungisa futhi asinacala nganoma yisiphi isenzo osithathayo kunoma iyiphi imoto. Yonke imininingwane ekulesi siza ivikelwe yi-copyright.
