Mapepala a OBD-II DTC

Utsi mpweya Aftertreatment wamafuta Anzanu SENSOR Dera

Kodi izi zikutanthauzanji?

Code Yovutikira Ndi Kuzindikira (DTC) ndi nambala yofalitsira ndipo imagwira ntchito pamagalimoto ambiri a OBD-II (1996 ndi atsopano). Izi zitha kuphatikizira, koma sikuchepera ku, Mercedes Benz, Mitsubishi, ndi zina zambiri. Ngakhale zili choncho, njira zowongolera zenizeni zimatha kusiyanasiyana kutengera mtundu wachitsanzo, kupanga, mtundu ndi kapangidwe kake.

Khodi yosungidwa ya P20DD m'galimoto yanu ya dizilo imatanthauza kuti powertrain control module (PCM) yapeza mphamvu yamagetsi pamayendedwe amafuta obwezeretsa mafuta pambuyo pake.

An Exhaust Aftertreatment System (yomwe imadziwikanso kuti Selective Catalyst Recovery System) imagwiritsidwa ntchito kupititsa patsogolo mphamvu za mpweya wothandizira. Itha kukhala ndi chimodzi mwazinthu zingapo; dizilo makutidwe ndi okosijeni chothandizira, particulate fyuluta, kuchepetsa wothandizila jekeseni wothandizila, amoniya Pepala chothandizira ndi nayitrogeni okusayidi (NOx) msampha.

Njira yochepetsera jekeseni imakhala ndi jakisoni wochepetsera m'modzi, thanki yosungira zochepetsera, komanso mizere yamafuta yochepetsera. Pampu yamagetsi yamagetsi nthawi zambiri imapezeka mu thanki kapena mu mzere wamafuta. The EAS mafuta kuthamanga sensa amalola Mtsogoleri kuwunika dongosolo kuthamanga pamene mpope chakudya ndi anatembenukira. Ndi m'dera lino momwe kusokonekera kudapezeka pomwe nambala ya P20DD idasungidwa.

Mwazina, utsi wamafuta pambuyo pothandizidwa (EAS) ali ndi udindo wobaya makina opangira mafuta / dizilo (DEF) mgulu lamafuta kumtunda kwa fyuluta yamtunduwu, msampha wa NOx ndi / kapena chosinthira chothandizira kudzera pa chosungira chamadzimadzi chokha. ndi jekeseni dongosolo. Majekeseni oyenerera a DEF amakweza kutentha kwa zinthu zosiyanasiyana zosefera ndikuwathandiza kuti azigwira bwino ntchito. Kuphatikizidwa kwa DEF pamakina othandizira kumakulitsa moyo wa zosefera ndikuchepetsa mpweya wotulutsa utsi mumlengalenga.

Machitidwe ndi zovuta za EAS zimayang'aniridwa ndikuwongoleredwa ndi PCM kapena wolamulira payokha (yemwe amagwirizana ndi PCM). Wowongolera amayang'anira kukakamizidwa kwa jekeseni wochepetsera, O2, NOx ndi masensa otentha a mpweya (komanso zolowetsa zina) kuti adziwe nthawi yoyenera ya jekeseni ya DEF (yochepetsa).

PCM ikazindikira kutulutsa kwamphamvu pamayendedwe amagetsi a EAS, nambala ya P20DD idzasungidwa ndipo nyali yowunikira ingayatse.

Kodi kuuma kwa DTC kumeneku ndi kotani?

Khodi yosungidwa ya P20DD iyenera kuchitidwa mozama ndipo iyenera kuchitidwa mwachangu momwe zingathere. Makina a EAS atha kuwonongeka chifukwa cha zomwe zidapangitsa kuti code ya P20DD ipitirire.

Kodi zina mwazizindikiro za code ndi ziti?

Zizindikiro za vuto la P20DD zitha kuphatikizira izi:

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

Kodi zina mwazomwe zimayambitsa codezi ndi ziti?

Zifukwa za code iyi zitha kuphatikizira izi:

• Opunduka mafuta kuthamanga kachipangizo EAS
• Cholakwika EAS mafuta mpope
• Tsegulani kapena dera lalifupi la zingwe zamagetsi zamagetsi zamagetsi zamagetsi za EAS
• Woyang'anira woyipa wa EAS / PCM kapena vuto la pulogalamu

Kodi masitepe a P20DD ndi otani?

Kuzindikira chikhombo cha P20DD kudzafunika chojambulira cha matenda, digito volt / ohmmeter (DVOM), ndi gwero lodziwitsa anthu zagalimoto.

Sakani Technical Bulletin (TSB) yomwe ikufanana ndi chaka chopanga, kupanga ndi mtundu wagalimoto; komanso kusamutsidwa kwa injini, ma code osungidwa, ndi zizindikilo zomwe zitha kupezeka zimatha kukupatsirani chidziwitso chazidziwitso chazidziwitso.

Ndimakonda kuyambitsa matenda anga poyang'ana m'maso ma waya ndi zolumikizira za EAS. Mawaya owotcha kapena owonongeka ndi / kapena zolumikizira ayenera kukonzedwa kapena kusinthidwa musanapite.

Ndikadapitilizabe kulumikiza sikani ndi cholumikizira chagalimoto ndikupeza ma nambala onse osungidwa ndi zomwe zimayimitsidwa pazithunzi. Lembani izi musanachotsere ma code. Yesani kuyendetsa galimotoyo mpaka PCM itayamba kukonzekera kapena nambala yake yachotsedwa.

Ngati PCM imayamba kukonzekera munthawi imeneyi, malamulowa amakhala apakatikati ndipo zimakhala zovuta kuzizindikira. Ngati ndi choncho, zomwe zidapangitsa kuti codeyo isungidwe zitha kuyenera kukulirakulira asanadziwe bwinobwino.

Ngati codeyo ikukhazikitsanso nthawi yomweyo, gawo lotsatira lakuzindikira lifunika kuti mufufuze komwe mungapeze zambiri zamagalimoto pazithunzithunzi zazithunzi, ma pini, nkhope zolumikizira, ndi njira zoyeserera ndi mawonekedwe ake.

Gwiritsani ntchito DVOM kuti muwone (kutsika kwamagetsi) m'malo onse operekera mafuta a EAS. Pitirizani kuyesa EAS dongosolo lowongolera magetsi. Onetsetsani mafyuzi ndi dera lolemera kuti mupewe kuzindikira molakwika.

Ngati ma fuseti onse ali bwino, gwiritsani ntchito DVOM kuyesa kuyesa kwa EAS zamagetsi zamagetsi ndi maseketi. Ngati chimodzi mwazigawozi sizikukwaniritsa zofunikira za wopanga, mukuganiza kuti ndizolakwika.

• Musaiwale Zapansi Zapansi Poyesa Voteji

Zokambirana zokhudzana ndi DTC

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

Mukufuna thandizo lina ndi kachidindo ka P20DD?

Ngati mukufunabe thandizo ndi DTC P20DD, 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.
