P20CF jakisoni wa pambuyo pa chithandizo cha A atapachika

Mapepala a OBD-II DTC

Utsi mpweya jakisoni mafuta pambuyo jekeseni A munakhala lotseguka

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 sizingokhala ku Mercedes Benz, Sprinter, GMC, Chevrolet, Ford, ndi zina zambiri. Ngakhale zambiri, njira zowongolera zenizeni zimatha kusiyanasiyana kutengera mtundu wachitsanzo, kapangidwe, kapangidwe ndi kapangidwe kake.

Ngati galimoto yanu ya dizilo ili ndi nambala ya P20CF yosungidwa, zikutanthauza kuti gawo loyendetsa mphamvu ya powertrain (PCM) silinazindikire mphamvu zamagetsi pambuyo poti mankhwala azitsatira a A. ...

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.

Mwazina, Exhaust Gas Aftertreatment Systems (EAS) ndi omwe amayenera kubaya jakisoni wa Dizilo Wochepetsa Agent / Exhaust Fluid (DEF) m'mafuta otulutsira kumtunda kwa fyuluta yamtunduwu, msampha wa NOx ndi / kapena chosinthira chothandizira kudzera pa chosungira chamadzimadzi chokha. ndi dongosolo la jekeseni. 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 ma O2, NOx ndi magetsi otulutsa mpweya (komanso zolowetsa zina) kuti adziwe nthawi yoyenera ya jekeseni ya DEF (yochepetsa). DEF iyenera kubayidwa nthawi yoyenera komanso moyenera kuti kutentha kwa gasi kuzikhala koyenera ndikukwaniritsa kusefera kwa zoipitsa.

PCM ikazindikira kusowa kwamagetsi pamagetsi oyendetsa jekeseni wamafuta a EAS, nambala ya P20CF idzasungidwa ndipo nyali yowunikira imatha kuwunikira.

Kodi kuuma kwa DTC kumeneku ndi kotani?

Khodi yosungidwa ya P20CF iyenera kuchitidwa mozama ndikuchotsa posachedwa. Makina a EAS atha kuwonongeka chifukwa cha zomwe zidapangitsa kuti code ya P20CF ipitirire.

Kodi zina mwazizindikiro za code ndi ziti?

Zizindikiro za P20CF DTC zitha kuphatikiza:

• 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 EAS mafuta injector
• Tsegulani kapena dera lalifupi mu dera la EAS loyendetsa mafuta
• Kusakwanira kwa DEF mosungira kwa EAS
• Woyang'anira woyipa wa EAS / PCM kapena vuto la pulogalamu

Kodi ndi njira ziti zina zothetsera P20CF?

Kuzindikira chikhombo cha P20CF kumafuna chojambulira cha matenda, digito volt / ohmmeter (DVOM), ndi gwero lodziwitsa 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 chikhazikitsidwacho chatsukidwa nthawi yomweyo, gawo lotsatira lakuzindikira lidzafunika kusanthula gwero lazidziwitso zamagalimoto pazithunzithunzi zazithunzi, zolumikizira zolumikizira, nkhope zolumikizira, ndi njira zoyeserera ndi mawonekedwe ake. Muthanso kugwiritsa ntchito gwero lazidziwitso zamagalimoto anu kuti mudziwe komwe kuli injini ya mafuta ya A EAS.

Gwiritsani ntchito DVOM kuti muwone (kutsitsa kwamagetsi) magetsi amtundu wa EAS. Onetsetsani mafyuzi okhala ndi dera lolemera kuti mupewe kuzindikira molakwika. Ngati magetsi oyenera (batri yamagetsi) ndi ma circuits apansi apezeka, gwiritsani ntchito sikani kuti mutsegule EAS mafuta injector (solenoid) ndikuyang'ana magetsi oyendetsa dera. Ngati voteji sakukwanira, ganizirani kuti wowongolera ali ndi vuto kapena ali ndi pulogalamu yolakwika.

Ngati dera lotulutsa magetsi lili mkati mwatsatanetsatane, gwiritsani ntchito DVOM kuyesa kuyesa kwa mafuta kwa EAS. Ngati jakisoni sakukwaniritsa zofunikira za wopanga, akuganiza kuti ndiye kuti sizinayende.

• EAS mafuta jekeseni ndi chabe jekeseni solenoid amene amapopera reductant madzi mu chitoliro utsi.
• 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 yanu ya P20CF?

Ngati mukufunabe thandizo ndi DTC P20CF, 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.
