P0420 Catalytic converter - kev ua tau zoo hauv qab qib tau txais (bank 1)

P0420 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0420 qhia tias lub catalytic converter (bank 1) efficiency yog qis dua qhov tau txais.

Qhov txhaum cai txhais li cas P0420?

Teeb meem code P0420 qhia tias catalytic converter (bank 1) tsis txaus. Qhov no txhais tau hais tias lub catalytic converter, uas yog tsim los ntxuav cov teeb meem emissions los ntawm lub cav tso zis, tsis ua nws txoj hauj lwm kom zoo. Lub catalytic converter yog tsim los purify cov teeb meem emissions uas yog tsim thaum lub sij hawm lub combustion ntawm roj nyob rau hauv lub internal combustion engine. Nws siv cov hlau meshes tshwj xeeb los hloov cov khoom tsis zoo rau hauv cov khoom muaj kev nyab xeeb.

Tej zaum ua rau

Qee qhov laj thawj vim li cas teeb meem code P0420 tuaj yeem tshwm sim:

• Faulty catalytic converter: Yog hais tias lub catalytic converter tau hnav, puas, los yog txhaws, nws yuav tsis ua hauj lwm kom zoo thiab tej zaum yuav tsis muab qhov zoo ntawm cov pa purification.
• Exhaust system xau: Cov pa hluav taws xob xau teeb meem, xws li cov kab nrib pleb lossis qhov nyob hauv qhov tso pa tawm los yog cov kav dej, tuaj yeem tso cua ntxiv rau hauv lub cev, uas tuaj yeem ua rau kev nyeem tsis raug ntawm cov pa oxygen sensors thiab P0420 code.
• Faulty oxygen sensors: Yog tias ib qho ntawm cov pa oxygen sensors tsis raug lossis tsim cov ntaub ntawv tsis raug, nws tuaj yeem ua rau P0420 code tshwm. Lub malfunction tej zaum yuav muaj feem xyuam rau lub sensor ntsia rau pem hauv ntej ntawm lub catalytic converter los yog ib tug ntsia tom qab nws.
• Teeb meem nrog cov roj txhaj tshuaj system: Kev sib xyaw tsis txaus lossis ntau dhau ntawm huab cua thiab roj vim muaj teeb meem nrog cov roj txhaj tshuaj tuaj yeem ua rau kev ua haujlwm tsis zoo ntawm catalytic converter thiab yog li P0420 code.
• Electronics teeb meem: Kev ua yuam kev lossis ua haujlwm tsis zoo hauv lub tshuab tswj hwm lub cav (ECM) lossis lwm yam khoom siv hluav taws xob hauv tsheb kuj tuaj yeem ua rau qhov teeb meem no tshwm sim.

Cov no tsuas yog qee qhov ua tau ntawm P0420 teeb meem code. Rau kev kuaj xyuas kom raug thiab daws qhov teeb meem, nws raug nquahu kom ua tiav kev kuaj mob ntawm lub tsheb ntawm lub chaw pabcuam tsheb tshwj xeeb.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0420?

Cov tsos mob uas nrog rau P0420 teeb meem code tuaj yeem sib txawv nyob ntawm seb qhov ua rau ntawm qhov yuam kev no, nrog rau cov xwm txheej ntawm lub tsheb, qee cov tsos mob tshwm sim yog:

• Check Engine Indicator: Cov tsos mob thiab teeb pom kev ntawm lub teeb pom kev ntawm lub teeb pom kev ntawm koj lub tsheb dashboard yog cov tsos mob feem ntau ntawm P0420 code. Qhov no tej zaum yuav yog thawj lub cim ntawm ib qho teeb meem nrog lub catalytic converter.
• Kev ua haujlwm degradation: Qee qhov xwm txheej, kev ua haujlwm ntawm lub cav yuav tsis zoo, lub zog yuav poob, lossis lub cav yuav khiav tsis zoo.
• Kev siv roj ntau ntxiv: Kev ua haujlwm tsis zoo ntawm lub catalytic converter tuaj yeem ua rau muaj roj ntau ntxiv vim qhov kev sib txuas tsis tiav ntawm cov roj los yog tsis raug tso pa ntxuav.
• Exhaust tsw: Cov ntxhiab tsw txawv txav tuaj yeem tshwm sim vim tsis txaus cov pa purification los ntawm catalytic converter.
• Vibrations los yog suab nrov: Yog tias muaj teeb meem loj nrog lub catalytic converter, kev vibrations lossis suab nrov txawv txawv yuav tshwm sim los ntawm qhov tso pa tawm.

Cov tsos mob no tuaj yeem tshwm sim hauv ntau qhov sib txawv thiab tej zaum yuav tshwm sim los ntawm cov teeb meem uas tsis yog teeb meem nrog lub catalytic converter. Yog tias cov tsos mob no tshwm sim, nws raug nquahu kom koj hu rau tus kws kho mob uas tsim nyog rau kev kuaj mob thiab kho.
