Mapepala a OBD-II DTC

Superheat chothandizira dongosolo, banki 1

Kodi izi zikutanthauzanji?

Code Yovutikira Kuzindikira (DTC) ndi nambala yodziwika bwino ndipo imagwira ntchito pamagalimoto ambiri a OBD-II (1996 ndi atsopano). Izi zitha kuphatikizira, koma sizingokhala mu, Ford, Hino, Mercedes Benz, VW, ndi zina zambiri. Ngakhale zili choncho, njira zowongolera zenizeni zimatha kusiyanasiyana kutengera mtundu wachitsanzo, kupanga, mtundu ndi kapangidwe kake.

Ngati code P200E yasungidwa pa galimoto yanu ya dizilo yokhala ndi OBD-II, zikutanthauza kuti gawo lowongolera la powertrain (PCM) lazindikira kutentha kwambiri kwa makina othandizira ku banki yoyamba ya injini. Bank 1 ndi gulu la injini lomwe lili ndi silinda yoyamba.

Dongosolo lothandizira m'galimoto yamakono yokhala ndi injini ya dizilo yomwe ikuyenda pamafuta okonda zachilengedwe idapangidwa kuti ichepetse mpweya woipa wotulutsa usanalowe mumlengalenga. Utsi umakhala makamaka wa ma hydrocarbon (HC), carbon monoxide (CO), nitrogen oxide (NOx) ndi particulate matter (mwaye - mu injini za dizilo). Chosinthira chothandizira ndichosefa chachikulu (chokhala ndi ma meshes abwino) chomwe chimatha kupirira kutentha kwambiri. Mpweya wotuluka mu injini umadutsamo, ndipo mpweya woipa umagwidwa ndi chinthu chosefera cha platinamu. Kutentha kwambiri komwe kumapangidwa mkati mwa chosinthira chothandizira kumathandiza kuwotcha mpweya woipa.

Makina othandizira amathandizira kuchepetsa (makamaka) zina zonse zotulutsa mpweya, ngakhale mapulogalamu ena amakhalanso ndi msampha wa NOx.

Machitidwe a Exhaust Gas Recirculation (EGR) amatenga gawo lina pochepetsa mpweya wa NOx. Komabe, mainjini amakono, amphamvu kwambiri a dizilo sangakwaniritse miyezo yolimba yochokera ku feduro (US) yokhala ndi EGR, chosinthira chothandizira ndi msampha wa NOx. Pachifukwa ichi, makina osankha othandizira othandizira (SCR) apangidwa.

Machitidwe a SCR amalowetsa Dizilo Exhaust Fluid (DEF) m'mafuta otulutsira kumtunda kwa fyuluta yamagulu ndi / kapena chosinthira chothandizira. Jekeseni woyesedwa bwino wa DEF umakweza kutentha kwa fyuluta ndikuilola kuti igwire bwino ntchito. Izi zimawonjezera moyo wautumiki wa fyuluta ndikuthandizira kuchepetsa mpweya wa utsi woipa mumlengalenga.

Ma sensor a kutentha kwa mpweya wotulutsa mpweya amayikidwa patsogolo ndi pambuyo pa chothandizira kuti ayang'ane kutentha kwake ndi mphamvu zake. Dongosolo lonse la SCS limayang'aniridwa ndikuwongoleredwa ndi PCM kapena woyang'anira yekha (omwe amalumikizana ndi PCM). Kupanda kutero, woyang'anira amayang'anira O2, NOx ndi magetsi otulutsa mpweya (komanso zolowetsa zina) kuti adziwe nthawi yoyenera ya jekeseni wa DEF. Jakisoni wa Precision DEF amafunikira kuti kutentha kwa gasi kukhale m'malo ovomerezeka ndikuwongolera kusefa kwa zinthu zoipitsa.

Ngati PCM iwona kutentha kwamphamvu kwambiri (pa mzere woyamba wa injini), nambala ya P200E idzasungidwa ndipo nyali yowonetsera kulephera ikhoza kubwera.

Kudula kwa fyuluta wamba:

Kodi kuuma kwa DTC kumeneku ndi kotani?

Ma code catalytic system aliwonse osungidwa amatha kukhala kalambulabwalo wa pulogalamu yotsekeka yotulutsa mpweya. Khodi ya P200E yosungidwa iyenera kuchitidwa mozama ndikuwongolera posachedwa. Zowonongeka zowonongeka zimatha kuchitika ngati zikhalidwe zomwe zathandizira kulimbikira kwa code sizikukonzedwa munthawi yake.

Kodi zina mwazizindikiro za code ndi ziti?

Zizindikiro za vuto la P200E zitha kuphatikizira izi:

• Kuchepetsa ntchito ya injini
• Utsi wakuda kwambiri wakutha kwa galimoto
• Kuchepetsa mafuta
• Zizindikiro zina zokhudzana ndi mpweya

Kodi zina mwazomwe zimayambitsa codezi ndi ziti?

Zifukwa za code iyi zitha kuphatikizira izi:

• Wosweka dongosolo SCR
• Woperewera SCR injector
• Madzi olakwika kapena osakwanira a DEF
• Opunduka utsi kachipangizo kutentha
• Woyang'anira SCR woyipa kapena pulogalamu yolakwika
• Kutulutsa kutayikira patsogolo pa chothandizira
• Kukhazikitsa kosakhala koyambirira kapena machitidwe apamwamba otulutsa utsi

Kodi ndi njira ziti zina zothetsera P200E?

Ngati zizindikiro za SCR nazonso zasungidwa, ziyenera kuchotsedwa musanayese kufufuza P200E yosungidwa. Kutulutsa kotulutsa mpweya kutsogolo kwa chosinthira chothandizira kuyenera kukonzedwa musanayese kuzindikira mtundu uwu wa code.

Kuti muzindikire kachidindo ka P200E, mufunika mwayi wopeza sikani yodziwira matenda, digito volt / ohmmeter (DVOM), thermometer ya infrared yokhala ndi cholozera cha laser, ndi gwero lazidziwitso zagalimoto.

Ngati mungapeze Technical Service Bulletin (TSB) yofanana ndi chaka chopanga, pangani ndi kupanga galimotoyo; komanso kusamutsidwa kwa injini, ma code / ma code osungidwa ndi zizindikiritso zomwe zitha kupezeka, zitha kukupatsirani chidziwitso chothandiza pakuzindikira.

Muyenera kuyambitsa matenda anu poyang'anitsitsa mawonekedwe a jakisoni wa SCR, kutulutsa masensa otenthetsera gasi, masensa a NOx, ndi zingwe zamagetsi zamagetsi ndi zolumikizira (02). Mawaya owotcha kapena owonongeka ndi / kapena zolumikizira ayenera kukonzedwa kapena kusinthidwa musanapite.

Kenako gwirizanitsani chojambulira ndi soketi yoyesera galimoto ndikutenga ma code onse osungidwa ndi chimango chofanana. Lembani zambirizi musanachotsere ma code ndikuyesa kuyendetsa galimotoyo mpaka PCM itayamba kukonzekera kapena nambala yake yasinthidwa.

Makhalidwewa ndi apakatikati ndipo akhoza kukhala ovuta kwambiri kuzindikira (pakali pano) ngati PCM itayamba kukonzekera. Poterepa, zinthu zomwe zidapangitsa kuti codeyo isungidwe zitha kufunikira kukulirakulira asanadziwe bwinobwino.

Ngati nambala yanu ikukhazikitsanso, fufuzani gwero lazidziwitso zamagalimoto anu kuti mupeze zojambula zoyeserera, zolumikizira zolumikizira, mawonekedwe olumikizira nkhope, ndi njira zoyeserera magawo ndi malongosoledwe. Mudzafunika mfundoyi kuti mutsirize gawo lotsatira pakupezeka kwanu.

Gwiritsani ntchito thermometer ya infrared kuti mudziwe kutentha kwenikweni kusanachitike kapena pambuyo pake. Onaninso kuyenda kwa sikani kuti mufananize zotsatira zanu zenizeni ndi zomwe zili pazenera. Onaninso zojambulazo kuchokera kumatensa otentha a mpweya pakati pamizere ya injini. Ngati kutentha kwa gasi kumapezeka, yang'anani masensa omwe akugwiritsa ntchito DVOM. Masensa omwe sakukwaniritsa zofunikira za opanga ayenera kuonedwa ngati olakwika.

Ngati masensa onse ndi ma circuits akugwira bwino ntchito, ganizirani kuti chothandizira chimakhala cholakwika kapena kuti dongosolo la SCR latha.

• Onetsetsani kuti damu la DEF ladzaza ndimadzimadzi oyenera ndipo makina a SCR akugwira bwino ntchito.

Zokambirana zokhudzana ndi DTC

• Pakadali pano palibe mitu yofananira m'mabwalo athu. Tumizani mutu watsopano pamsonkhano tsopano.

Mukufuna thandizo lina ndi nambala ya P200E?

Ngati mukufunabe thandizo ndi DTC P200E, lembani funso mu ndemanga pansipa pamutuwu.

ZINDIKIRANI. Izi zimaperekedwa kuti zidziwitse zokha. Sikuti tizigwiritsa ntchito ngati malingaliro okonzanso ndipo sitili ndi udindo pazomwe mungachite pagalimoto iliyonse. Zomwe zili patsamba lino ndizotetezedwa ndi zovomerezeka.
