P2201 Mercedes: Kawm txog cov kab mob sib kis

Yog tias koj muaj lub tsheb Mercedes-Benz, tej zaum koj tau ntsib P2201 Mercedes Diagnostic Trouble Code (DTC) ntawm qee lub sijhawm.Cov cai no muaj feem xyuam rau lub tsheb lub cav tswj module (ECM) thiab tuaj yeem qhia tau tias muaj teeb meem nrog lub kaw lus.Hauv tsab xov xwm no, peb yuav ua tib zoo saib ntawm P2201 code, nws lub ntsiab lus, ua tau, thiab cov kev daws teeb meem.

Yog li, P2201 Mercedes code txhais li cas?Cov cai no qhia txog teeb meem nrog ECM's NOx sensor circuit range/performance.Qhov tseem ceeb, nws qhia tau hais tias ECM tau kuaj pom lub teeb liab tsis raug los ntawm NOx sensor, uas yog lub luag haujlwm rau ntsuas qib nitric oxide thiab nitrogen dioxide hauv cov pa.Cov qib no pab ECM saib xyuas kev ua haujlwm ntawm lub tsheb lub emissions system.

Tam sim no, cia peb tham txog qee qhov laj thawj ntawm P2201 Mercedes code.Ib qho ntawm cov laj thawj tseem ceeb vim li cas cov cai no tshwm sim yog qhov tsis raug NOx sensor.Nyob rau tib lub sijhawm, cov sensors no tuaj yeem degrade lossis ua paug, ua rau kev nyeem tsis raug.Lwm qhov ua rau muaj teeb meem nrog cov xaim lossis cov txuas txuas nrog NOx sensor.Kev sib txuas xoob lossis cov xov hlau puas tuaj yeem cuam tshuam kev sib txuas lus ntawm lub sensor thiab ECM, ua rau P2201 code.

Tsis tas li ntawd, qhov yuam kev ECM tuaj yeem ua rau P2201 code.Yog tias ECM nws tus kheej tsis ua haujlwm zoo, nws yuav tsis tuaj yeem txhais qhov tseeb ntawm NOx sensor teeb liab, ua rau kev nyeem ntawv yuam kev.Lwm yam ua rau muaj xws li tso pa tawm, lub tshuab nqus tsev vacuum, lossis txawm tias catalytic converter tsis ua haujlwm.Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tau ua kom tiav kev kuaj mob los txiav txim seb qhov laj thawj tiag tiag ntawm txoj cai.

Yog tias koj ntsib P2201 Mercedes code, nco ntsoov tsis txhob tsis quav ntsej nws.Txawm hais tias lub tsheb tseem tuaj yeem ua haujlwm ib txwm, qhov teeb meem hauv qab no tuaj yeem cuam tshuam rau koj lub Mercedes-Benz kev ua tau zoo thiab emissions.Yog li ntawd, nws raug nquahu kom nqa lub tsheb mus rau tus kws kho tsheb uas tsim nyog lossis tus tswv lag luam Mercedes-Benz txhawm rau kuaj xyuas thiab kho.

Thaum lub sijhawm kuaj mob, cov kws tshaj lij yuav siv cov cuab yeej tshwj xeeb los nyeem cov lej txhaum thiab khaws cov ntaub ntawv ntxiv los ntawm ECM.Lawv kuj tseem yuav xyuas NOx sensor, thaiv, thiab cov khoom sib txuas rau cov cim qhia ntawm kev puas tsuaj lossis ua haujlwm tsis zoo.Thaum lub hauv paus ua rau txiav txim siab, kev kho kom tsim nyog tuaj yeem ua tau.

Qhov kev kho yuav tsum tau ua rau P2201 chaws yuav txawv nyob ntawm qhov teeb meem hauv qab no.Yog tias qhov tsis raug NOx sensor yog qhov ua txhaum, nws yuav tsum tau hloov.Ib yam li ntawd, yog cov xaim lossis cov khoom sib txuas puas lawm, lawv yuav tsum tau kho lossis hloov.Qee zaum, ECM nws tus kheej yuav tsum tau reprogrammed lossis hloov.

Hauv cov ntsiab lus, P2201 Mercedes code yog ib qho teeb meem kev kuaj mob uas qhia tias muaj teeb meem nrog ECM's NOx sensor circuit range / kev ua tau zoo.Paub tias txoj cai txhais li cas thiab qhov ua tau tshwm sim tuaj yeem pab koj daws qhov teeb meem tam sim ntawd.Yog tias koj ntsib tus lej P2201, nws raug nquahu kom nrhiav kev pab cuam kom raug kuaj xyuas thiab daws qhov teeb meem.Los ntawm kev ua cov kauj ruam tsim nyog, koj tuaj yeem xyuas kom meej tias koj lub Mercedes-Benz txuas ntxiv ua haujlwm zoo thaum tswj kev ua haujlwm zoo tshaj plaws.
