P20D7 Exhaust Gas Treatment System Fuel Control Circuit / Open

Mapepala a OBD-II DTC

Kutulutsa mpweya wotsatira njira yothandizira mafuta / kutseguka

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 sikuchepera ku, VW, Audi, Mercedes Benz, Ford, Mitsubishi, ndi zina zambiri. Ngakhale zili choncho, njira zowongolera zenizeni zimatha kusiyanasiyana kutengera mtundu wachitsanzo, kupanga, kapangidwe kake ndi kapangidwe kake.

Khodi yosungidwa P20D7 m'galimoto yanu ya dizilo ikutanthauza kuti gawo loyendetsa mphamvu yamagetsi (PCM) silinazindikire mphamvu yamagetsi pambuyo poyendetsa mafuta.

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. Ndili m'dongosolo lomwe limayang'anira pampu yodyetserayi pomwe vuto losungira P20D7 lidapezeka.

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 kusowa kwamagetsi mu gawo loyendetsa mafuta la EAS, nambala ya P20D7 idzasungidwa ndipo nyali yosonyeza kuwonongeka itha kuwunikira.

Kodi kuuma kwa DTC kumeneku ndi kotani?

Khodi yosungidwa ya P20D7 iyenera kuchitidwa mozama ndikukonzanso posachedwa. Makina a EAS atha kuwonongeka chifukwa cha zinthu zomwe zidapangitsa kuti code ya P20D7 isapitirire.

Kodi zina mwazizindikiro za code ndi ziti?

Zizindikiro za vuto la P20D7 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:

• Cholakwika EAS mafuta mpope
• Opunduka mafuta kuthamanga kachipangizo EAS
• Tsegulani kapena dera lalifupi mu gawo loyendetsa magetsi la EAS
• Kusakwanira kwa DEF mosungira kwa EAS
• Woyang'anira woyipa wa EAS / PCM kapena vuto la pulogalamu

Kodi ndi njira ziti zina zothetsera P20D7?

Kuzindikira chikhombo cha P20D7 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 amafuta a EAS. Pitirizani kuyesa EAS dongosolo lowongolera magetsi. Onetsetsani mafyuzi okhala ndi dera lolemera kuti mupewe kuzindikira molakwika. Ngati mphamvu yolondola (batri yamagetsi) ndi ma circuits apansi apezeka, gwiritsani ntchito sikani kuyatsa mpope wamafuta wa EAS ndikuyang'ana magetsi oyendetsa dera. Ngati voteji ndi osakwanira, onani EAS mafuta mpope kulandirana. Ngati palibe magetsi olowera omwe akupezeka, ganizirani kuti wowongolera ali ndi vuto kapena ali ndi pulogalamu yolakwika. Ngati magetsi athandizira alipo koma kulibe magetsi omwe amapezeka, ganizirani kuti kulandirako ndikolakwika.

Ngati magetsi oyendera magetsi a EAS ali mkati mwamagawo, gwiritsani ntchito DVOM kuyesa kuyesa kwa EAS ndi pampu yamafuta. 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 nambala ya P20D7?

Ngati mukufunabe thandizo ndi DTC P20D7, 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.
