Xyuas kom tseeb tias qhov kev tiv thaiv qhov tseem ceeb nyob rau hauv qhov ib txwm muaj raws li tau teev tseg hauv cov ntaub ntawv kev qhia rau koj lub tsheb tshwj xeeb tsim thiab qauv.
3. Txheeb xyuas cov khoom siv hluav taws xob: Siv lub multimeter, xyuas cov khoom siv hluav taws xob ntawm cov pa oxygen sensor connector. Xyuas kom tseeb tias qhov voltage ua tau raws li cov neeg tsim khoom specifications.
4. Tshawb xyuas cov kab hluav taws xob: Xyuas cov pa oxygen sensor teeb liab xov hlau rau corrosion, tawg, lossis lwm yam kev puas tsuaj. Hloov cov xov hlau puas yog tias tsim nyog.
5. Txheeb xyuas qhov xwm txheej ntawm oxygen sensor: Yog tias tag nrho cov kauj ruam dhau los tsis daws qhov teeb meem, cov pa oxygen sensor yuav ua yuam kev thiab yuav tsum tau hloov. Qhov no feem ntau yog tshem tawm lub sensor thiab xyuas nws qhov tsis kam lossis voltage siv lub multimeter.
6. Tshawb xyuas ECM: Yog tias tag nrho lwm cov khoom kuaj xyuas thiab ua haujlwm zoo, qhov teeb meem yuav yog nrog lub Cav Tswj Module (ECM). Hauv qhov no, yuav tsum muaj kev kuaj mob ntxiv, ua los ntawm tus kws tshaj lij uas tsim nyog siv cov cuab yeej tshwj xeeb.

Kev kuaj mob yuam kev

Thaum kuaj pom DTC P0142, cov teeb meem hauv qab no yuav tshwm sim:

• Kev txhais cov ntaub ntawv tsis raug: Qhov yuam kev tuaj yeem tshwm sim vim kev txhais lus tsis raug ntawm cov ntaub ntawv tau txais los ntawm oxygen sensor. Kev nkag siab tsis meej ntawm qhov hluav taws xob lossis qhov tsis kam tiv thaiv tuaj yeem ua rau cov lus xaus tsis raug txog qhov ntsuas qhov ntsuas.
• Kev txiav txim siab tsis raug: Lwm qhov yuam kev yog qhov tsis raug txheeb xyuas qhov ua rau ntawm qhov teeb meem. Qee tus kws kho tsheb tuaj yeem xav tias qhov teeb meem yog nrog oxygen sensor nws tus kheej yam tsis tau kuaj xyuas lwm yam ua tau, xws li cov xov hlau puas lossis teeb meem nrog ECM.
• Tsis muaj kev kuaj xyuas cov khoom ntxiv: Qee zaum cov kws kho tsheb tuaj yeem hla kev kuaj xyuas lwm cov khoom siv hluav taws xob, xws li cov hloov pauv catalytic lossis lim cua, uas tuaj yeem ua rau P0142 teeb meem code.
• Kev siv cov khoom siv tsis zoo: Qee qhov yuam kev tuaj yeem tshwm sim vim yog siv cov khoom siv tsis tsim nyog lossis tsis muaj peev xwm ntawm tus kws tshaj lij thaum ua kev kuaj mob. Kev siv hom multimeter tsis raug lossis tsis nkag siab tag nrho yuav ua li cas lub kaw lus ua haujlwm tuaj yeem ua rau cov lus xaus tsis raug.

Txhawm rau tiv thaiv cov teeb meem no, nws yog ib qho tseem ceeb uas yuav tsum muaj kev nkag siab zoo txog kev tswj hwm lub cav, txhais cov ntaub ntawv kom raug thiab ua tiav kev kuaj mob siv cov cuab yeej tsim nyog thiab cov txheej txheem.

Txoj cai txhaum loj npaum li cas? P0142?

Teeb meem code P0142 qhia txog teeb meem nrog oxygen sensor. Txawm hais tias cov cai no tsis yog ib qho loj tshaj plaws, nws tseem yuav tsum tau ua tib zoo saib xyuas thiab kho. Cov pa oxygen sensor ua haujlwm tsis zoo tuaj yeem ua rau lub cav ua haujlwm tsis zoo, nce emissions, thiab txawm tias poob lub zog thiab siv roj ntau ntxiv. Nws yog ib qho tseem ceeb kom paub sai sai thiab kho qhov teeb meem no kom tsis txhob muaj teeb meem loj dua yav tom ntej.

Kev kho dab tsi yuav pab tshem tawm cov cai? P0142?
