P2225 NOx Sensor Rhaub Sensor Circuit Sib Piv Bank 2

OBD-II DTC Cov Ntaub Ntawv

Cov teeb liab sib cuam tshuam ntawm NOx sensor heater sensor circuit, bank 2

Qhov no txhais li cas?

Qhov no yog lub zog ntsuas hluav taws xob kuaj pom teeb meem (DTC) thiab feem ntau siv rau tsheb OBD-II. Cov npe tsheb tuaj yeem suav nrog, tab sis tsis txwv rau, Mercedes-Benz, Sprinter, VW, Audi, Ford, Dodge, Ram, Jeep, thiab lwm yam.

NOx (nitrogen oxide) sensors feem ntau yog siv rau emission systems hauv diesel xyaw. Lawv lub hom phiaj tseem ceeb yog los txiav txim siab txog qib ntawm NOx tawm ntawm cov pa pa tom qab combustion nyob rau hauv lub combustion chamber. Lub kaw lus tom qab ntawd ua rau lawv siv ntau txoj hauv kev. Muab cov kev ua haujlwm hnyav ntawm cov sensors no, lawv tau tsim los ntawm kev sib xyaw ntawm cov ceramic thiab ib hom zirconia.

Ib qhov tsis zoo ntawm NOx cov pa mus rau huab cua yog tias qee zaum lawv tuaj yeem ua rau muaj pa taws thiab / lossis cov kua qaub. Kev ua tsis tiav kom tswj tau zoo thiab tswj cov qib NOx yuav ua rau muaj kev cuam tshuam loj heev rau huab cua ib puag ncig peb thiab huab cua peb nqus pa. ECM (Kev Tswj Xyuas Lub Tshuab) niaj hnub saib xyuas NOx cov cuab yeej kom ntseeg tau qib tso pa tawm hauv koj lub tsheb cov pa roj av.

Lub cav tswj module (ECM) tuaj yeem xam cov nitrogen oxide thiab nitrogen dioxide (NOx) gases siv cov ntaub ntawv uas tau txais los ntawm lub tsheb cov dej ntws thiab downstream oxygen sensors ua ke nrog NOx sensor nyeem ntawv. ECM ua qhov no los tswj cov theem ntawm NOx tawm ntawm lub tailpipe rau ib puag ncig emission vim li cas. Lub txhab nyiaj 2 tau hais hauv cov lej teeb meem yog lub cav thaiv uas tsis muaj lub tog raj kheej # 1.

P2225 yog ib txoj cai piav qhia raws li NOx Sensor Heater Sensor Circuit Intermittent Bank 2, uas txhais tau hais tias ECM tau kuaj pom qhov tsis sib xws hauv kev ua haujlwm tag nrho ntawm NOx Sensor Heater Sensor Circuit Court.

Diesel cav tshwj xeeb tshaj yog tsim kom muaj cua sov ntau, yog li nco ntsoov cia lub tshuab txias ua ntej ua haujlwm ntawm ib qho ntawm cov tshuab ua pa.

Piv txwv ntawm NOx sensor (qhov no rau GM tsheb):

Dab tsi yog qhov hnyav ntawm DTC no?

Yog tias DTCs tsis quav ntsej thiab tsis tau kho qhov ua tau zoo, nws tuaj yeem ua rau catalytic hloov pauv tsis ua haujlwm. Tawm ntawm cov tsos mob thiab ua rau cov DTCs tsis tau kho tuaj yeem ua rau muaj teeb meem ntxiv rau koj lub tsheb, xws li nres tas li thiab txo kev siv roj. Yog tias koj pom ib qho ntawm cov tsos mob tshwm sim hauv cov npe hauv qab no, nws tau pom zoo tias koj tau txais kev tshuaj xyuas los ntawm tus kws tshaj lij.

Cov tsos mob ntawm txoj cai yog dab tsi?

Cov tsos mob ntawm P2225 tus lej kuaj mob tuaj yeem suav nrog:

• Tsis tu ncua
• Cav tsis pib thaum kub
• Ua kom lub cav tsis zoo
• Tej zaum yuav muaj suab nrov thiab / lossis kev co thaum ua kom nrawm dua.
• Lub cav tuaj yeem ua haujlwm ntshiv lossis nplua nuj tshwj xeeb ntawm ntug dej # 2.

Dab tsi yog qee qhov ua rau pom cov cai?

Yog vim li cas rau qhov P2225 NOx sensor code yuav suav nrog:

• Catalytic converter puas
• Cov roj sib tov tsis raug
• Ua tsis tiav cov ntsuas cua txias
• Manifold cua siab sensor tawg
• Muaj teeb meem nrog huab cua loj txaus sensor
• Roj txhaj ib feem puas
• Cov roj siab tswj hwm tawg
• Muaj qhov tsis zoo
• Muaj qhov xau los ntawm qhov tso pa tawm, nplawm hose, nqes dej, lossis qee yam khoom siv ntawm cov pa tso tawm.
• Cov pa oxygen tawg

Dab tsi yog qee cov kauj ruam txhawm rau txheeb xyuas thiab daws teeb meem P2225?

Thawj kauj ruam hauv txheej txheem daws teeb meem yog los tshuaj xyuas cov ntawv xov xwm kev pabcuam (TSBs) kom paub cov teeb meem nrog lub tsheb tshwj xeeb.

Cov txheej txheem kuaj mob tau dhau los ua lub tsheb tshwj xeeb thiab yuav xav tau cov cuab yeej tsim nyog thiab kev paub kom tau ua kom raug. Peb piav qhia cov theem pib hauv qab no, tab sis hais txog koj lub tsheb / ua / qauv / kev kho cov ntawv kho mob rau cov qib tshwj xeeb rau koj lub tsheb.

Kauj ruam yooj yim # 1

Thawj kauj ruam yuav tsum yog txhawm rau tshem cov lis dej num thiab rov ntsuas lub tsheb. Yog tias tsis muaj DTCs (Diagnostic Trouble Codes) tshwm sim tam sim ntawd, siv sijhawm sim ntev nrog ob peb nres kom pom tias lawv rov tshwm sim dua. Yog tias ECM (lub cav tswj lub cav) rov ua haujlwm tsuas yog ib ntawm cov lej, txuas ntxiv kev kuaj mob rau tus lej tshwj xeeb ntawd.

Kauj ruam yooj yim # 2

Tom qab ntawd koj yuav tsum kuaj xyuas qhov tso pa tawm. Cov pob zeb dub nyob ib puag ncig cov kab nrib pleb thiab / lossis cov kab ke kaw lus yog ib qho cim zoo ntawm kev xau. Qhov no yuav tsum tau ua raws li, feem ntau cov pa gasket yog yooj yim los hloov. Lub kaw lus kaw tag nrho yog qhov tseem ceeb ntawm cov sensors koom nrog hauv koj qhov tso pa tawm.

Kauj ruam yooj yim # 3

Nrog tus pas ntsuas kub infrared, koj tuaj yeem saib xyuas qhov ntsuas kub ntawm cov pa tso ua ntej thiab tom qab hloov pauv catalytic. Tom qab ntawd koj yuav tsum sib piv cov txiaj ntsig nrog cov chaw tsim khoom tshwj xeeb, yog li xa mus rau koj phau ntawv pabcuam tshwj xeeb rau qhov ntawd.

Kauj ruam yooj yim # 4

Yog tias qhov ntsuas kub ntawm qhov hloov pauv catalytic nyob hauv qhov tshwj xeeb, xyuam xim rau cov txheej txheem hluav taws xob cuam tshuam nrog cov ntsuas no. Pib nrog cov hlua hlau thiab lub txhab nyiaj 2 NOx sensor txuas. Kho cov xov hlau puas los ntawm kev siv cov kab sib txuas thiab ua rau lawv nqaim. Kuj txheeb xyuas cov pa oxygen siv hauv txhab nyiaj 2 kom ntseeg tau tias lawv tsis raug puas tsuaj, uas tuaj yeem muaj peev xwm hloov pauv qis hauv qab NOx nyeem ntawv. Kho ib qho txuas uas tsis txuas txaus lossis tsis xauv kom raug.

Kab lus no yog rau cov ntaub ntawv xov xwm nkaus xwb thiab cov ntaub ntawv thev naus laus zis thiab cov ntawv xov xwm pabcuam rau koj lub tsheb tshwj xeeb yuav tsum yog qhov tseem ceeb tshaj plaws.
