P2003 Dizilo Particulate Sefa Mwachangu Pansi pa B2 Threshold

Mapepala a OBD-II DTC

Kuchita bwino kwa Dizilo Particulate Pansi Pansi pa Threshold Bank 2

Kodi izi zikutanthauzanji?

Code Yovutikira Kuzindikira (DTC) ndi nambala yotumizira. Imawerengedwa kuti ndiyaponseponse momwe imagwirira ntchito popanga mitundu yonse yamagalimoto (1996 ndi atsopano), ngakhale njira zowongolera zingasiyane pang'ono kutengera mtunduwo.

DTC imatanthawuza chipangizo chowongolera mpweya chotchedwa particulate filter. Idakhazikitsidwa mu 2007 ndipo kenako ma dizilo, imachotsa mwaye pamipweya yawo yotulutsa mpweya. Mutha kuwona DTC iyi pamagalimoto onyamula dizilo ochokera ku Dodge, Ford, Chevrolet kapena GMC, koma imathanso kugwira ntchito pamagalimoto ena adizilo monga VW, Vauxhall, Audi, Lexus, ndi zina zambiri.

DPF - diesel particulate fyuluta - imatenga mawonekedwe a chosinthira chothandizira ndipo ili muutsi wamagetsi. Mkati mwake muli matrix azinthu zophimba ndime monga cordierite, silicon carbide, ndi ulusi wachitsulo. Mphamvu yochotsa mwaye ndi 98%.

Chithunzi chodula cha fyuluta yamagulu (DPF):

DPF imapanga kupanikizika pang'ono kumbuyo panthawi yogwira ntchito. ECU yagalimoto - kompyuta - ili ndi zowunikira zokankhira pazosefera kuti ziwongolere ntchito yake. Ngati pazifukwa zilizonse - pazigawo ziwiri za ntchito - imazindikira kusiyana pakati pazovuta, imayika code P2003 yosonyeza cholakwika.

Osadandaula, zida izi zimatha kusinthika kuti zitenthe mwaye wochuluka ndikubwerera kuntchito yabwinobwino. Zimakhala nthawi yayitali.

Izi zikachitika, magetsi adzazimitsa ndipo code idzayera. Ndicho chifukwa chake imatchedwa code code - imasonyeza cholakwika mu "nthawi yeniyeni" ndikuyichotsa pamene cholakwikacho chikukonzedwa. Khodi yolimba imakhalabe mpaka kukonzanso kutha ndipo codeyo imachotsedwa pamanja pogwiritsa ntchito scanner.

Magalimoto onse amafuna chida chotsitsira ma oxide a nitrojeni omwe amatumizidwa mumlengalenga, omwe bwenzi atapanda kukhala omwe ali ovulaza thanzi lanu komanso mlengalenga. Chosinthira chothandizira chimachepetsa mpweya kuchokera ku injini zamafuta. Kumbali inayi, dizilo ndivuto kwambiri.

Popeza kutentha kwamafuta oponderezedwa kwambiri kumagwiritsidwa ntchito kuyaka modzidzimutsa, kutentha kwa mitu ya silinda kumakhala kokwera kwambiri, zomwe zimapangitsa kuti ma nitrogen oxide azitha kuswana. NOx imapangidwa pa kutentha kwambiri. Mainjiniya adadziwa kuti akuyenera kugwiritsa ntchito EGR - Exhaust Gas Recirculation - kuti achepetse mafuta omwe akubwera kuti achepetse kutentha kwamutu ndikuchepetsa mpweya wa NOx. Vuto linali loti kutentha kwa dizilo kunali kokwera kwambiri ndipo kunangowonjezera vutolo.

Anakonza izi pogwiritsa ntchito choziziritsira injini kuziziritsa mafuta a injini ndi chitoliro cha EGR kuti kutentha kwa silinda kukhale pansi komwe kumafunika kupanga NOx. Zinagwira ntchito bwino kwambiri. DPF ndiye njira yomaliza yodzitchinjiriza ku utsi pochotsa mwaye.

ZINDIKIRANI. DTC P2003 iyi ndi yofanana ndi P2002, koma P2003 ikugwira ntchito ku banki 2, yomwe ili mbali ya injini yomwe ilibe silinda 1.

Zizindikiro

Zizindikiro za vuto la P2003 zitha kuphatikiza:

• Kutsika kwachuma kwamafuta kumachitika pomwe makina oyang'anira injini amayesa kukweza kutentha kwa mpweya kuti uwonongere mwaye mu DPF.
• Kuwala kwa injini yoyang'ana ndi nambala P2003 kudzawala. Kuunikako kumatha kukhalabe kounikira nthawi ndi nthawi mukamakonzanso DPF. Injiniyo imakhala yaulesi ikamathamanga.
• Mafuta a injini awonetsa kuchepa chifukwa cha ma ECM omwe akuyesera kukweza kutentha kwa injini. Magalimoto ena amakhala patsogolo pang'ono pofika nthawi ya jakisoni wamafuta pambuyo pa gawo lapakati kuti awotche pang'ono mafuta kuti atenthe kutentha kwa mpweya wotulutsa utsi. Ena mwa mafutawa amalowa mu crankcase. ECM ikawona kufunika kwakubwezeretsanso kwa DPF, moyo wamafuta umachepa kwambiri.
• Ngati DPF siyikonzedwe, ECU ibwerera ku "Limp Home Mode" mpaka zinthu zitakonzedwa.

Zotheka

Zifukwa za DTC iyi zitha kuphatikiza:

• Khodi iyi ipangitsa kuthamanga kwambiri pang'onopang'ono. Kuti uwotche mwaye mu DPF umafuna kutentha kwa 500 ° C mpaka 600 ° C. Ngakhale ECU ikuyesa kuyendetsa injini, ndizovuta kuti ipange kutentha kokwanira kuyeretsa DPF pama injini ochepa.
• Kutulutsa kwamlengalenga kutsogolo kwa DPF kumasintha kuwerenga kwa sensa, ndikupangitsa code
• Njira zolakwika kapena zigawo za ECU zimalepheretsa kusinthika koyenera.
• Mafuta okhala ndi sulufule kwambiri amatseketsa DPF mwachangu
• Zida zina zakutsogolo ndi zosintha magwiridwe antchito
• Akuda mpweya fyuluta amafotokozera
• Kuwonongeka kwa DPF

Njira zowunikira ndi njira zothetsera mavuto

Mayankho ake ndi ochepa chifukwa DPF siyolakwika, koma yodzaza ndi tinthu tating'onoting'ono. Ngati magetsi ayatsidwa ndipo nambala ya P2003 yakhazikitsidwa, tsatirani njira yothetsera mavuto kuyambira pakuwunika.

Yendani DPF pa block # 2 kuti muone kulumikizana kulikonse komwe kuli mbali ya injini komwe kumalumikizidwa ndi chitoliro chotulutsa utsi.

Yang'anani kutsogolo kwa DPF kutsogolo ndi kumbuyo kosinthira (block 2). Fufuzani mawaya opsereza, zolumikizira zotayirira kapena zovunda. Chotsani zolumikizira ndikuyang'ana zikhomo zopindika kapena zonyowa. Onetsetsani kuti mawaya amagetsi sakukhudza DPF. Yambitsani katunduyo ndipo yang'anani kutuluka kapena makina.

Ngati zonse zikuyenda bwino ndi izi, yendetsani galimotoyo kwa mphindi pafupifupi 30 pamsewu wothamanga kuti utulutse mpweya wotentha wokwanira kukonzanso DPF. Inemwini, ndapeza kuti kuyendetsa injini mozungulira pa 1400 rpm kwa mphindi pafupifupi 20 kumapereka zotsatira zomwezi.

Ngati vutoli likupitilirabe mutayendetsa pagalimoto pamsewu, ndibwino kuti mupite nalo m'sitolo ndikufunsani kuti liyike pamakompyuta azachipatala monga Tech II. Sili okwera mtengo ndipo amatha kuyang'anira masensa ndi ma ECU munthawi yeniyeni. Amatha kuwona ma sign kuchokera kuma sensors ndikuwona ngati ECU ikuyesetsanso kusinthanso. Gawo loyipa limayamba kuwonekera mwachangu.

Ngati mumayendetsa mozungulira tawuni ndipo ili ndi vuto lomwe limachitika mobwerezabwereza, pali yankho lina. Masitolo ambiri amatha kukonzanso kompyuta yanu kuti zisawonongeke masekondi ochepa. Kenako chotsani PDF ndikusintha ndi chitoliro chowongoka (ngati chilololedwa m'manja mwanu). Vutoli lathetsedwa. Osataya DPF ngakhale, zimawononga ndalama zambiri ngati mutagulitsa kapena kufunikira mtsogolo.

ZINDIKIRANI. Zosintha zina monga "zida zoziziritsira mpweya" (CAI) kapena zida zotulutsa utsi zimatha kuyambitsa nambala iyi komanso zingakhudze chitsimikizo cha wopanga. Ngati mwasinthidwa motere ndi nambala iyi, ikani gawo lolowera m'malo mwake kuti muwone ngati nambala yake yasowa. Kapena yesani kulumikizana ndi wopanga zida kuti mumve ngati ili ndi vuto.

Zokambirana zokhudzana ndi DTC

• Khodi yolakwika P2003 ya Nissan Altima 2007 3.5Anga ndi nissan altima 2007 3.5 SE. Anawonetsa chizindikiro chautumiki wa injini ndipo nditalankhula ndi makaniko adapeza cholakwika cha P2003. Koma akuti ndizodabwitsa kupeza nambala yagalimoto yamafuta. Ndikufuna thandizo kuti ndidziwe chomwe chiri. 🙄: pinda:... 

Mukufuna thandizo lina ndi nambala yanu ya p2003?

Ngati mukufunabe thandizo ndi DTC P2003, 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.
