P2052 Reductant Injection Valve Circuit Bank 2 Bank 1

Mapepala a OBD-II DTC

Reductant jekeseni valavu Dera Bank 2 Bank 1 High

Kodi izi zikutanthauzanji?

Code Yovutikira Ndi Kuzindikira (DTC) ndi nambala yofalitsira ndipo imagwira ntchito pamagalimoto ambiri a OBD-II (1996 ndi atsopano). Izi zingaphatikizepo, koma sizingokhala ku, Ford, Mercedes Benz, Sprinter, Smart, Ram, ndi zina zambiri. Ngakhale zili zachilendo, njira zowongolera zenizeni zimatha kusiyanasiyana kutengera mtundu wachitsanzo, kapangidwe, kapangidwe kake ndi kapangidwe kake.

Khodi yosungidwa P2052 imatanthauza kuti powertrain control module (PCM) yapeza kuti chiwombankhanga chikuyenda bwino poyendetsa jekeseni wochepetsera wa banki yachiwiri ya injini komanso njira yoyamba yosankhira othandizira (SCR). Bank 2 imatanthawuza gulu la injini lomwe LALIBE silinda nambala wani.

Makina othandizira amathandizira kuchepetsa (makamaka) 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 akuluakulu amakono, amphamvu kwambiri a dizilo sangakwaniritse miyezo yolimba yochokera ku feduro (US) yokhala ndi dongosolo la EGR, chosakanizira chosinthira, ndi chopezera cha NOx. Pachifukwa ichi, makina osankha othandizira othandizira (SCR) apangidwa.

Machitidwe a SCR amalowetsa kapangidwe kochepetsera kapena Dizilo Exhaust Fluid (DEF) m'mafuta otulutsira kumtunda kwa fyuluta yamtunduwu, msampha wa NOx ndi / kapena chosinthira chothandizira kudzera pa valve yochepetsera jekeseni (solenoid). Jekeseni woyesedwa bwino wa DEF umakweza kutentha kwa fyuluta ndikuilola kuti igwire bwino ntchito. Izi zimawonjezera moyo wautumiki pazinthu zosefera ndikuthandizira kuchepetsa mpweya wa utsi woipa mumlengalenga.

Dongosolo lonse la SCR limayang'aniridwa ndikuyang'aniridwa ndi PCM kapena wolamulira payekha (yemwe amagwirizana ndi PCM). Mulimonsemo, wowongolera amayang'anira O2, NOx ndi kutulutsa masensa otenthetsera mpweya (komanso zolowetsa zina) kuti adziwe nthawi yoyenera ya jakisoni wa DEF (reductant). Mwatsatanetsatane jekeseni DEF chofunika kusunga utsi mpweya kutentha mkati magawo zovomerezeka ndi konza moyenera kusefera wa zoipitsa.

Kuchepetsa zotenthetsera zomwe zimagwiritsidwa ntchito popewera ma injini ya dizilo kuti isaziziritse ndi kuzizira kwambiri. Izi zotenthetsera nthawi zambiri zimakhala mu nkhokwe ya DEF ndi / kapena mu payipi (s) yamphuno yochepetsera.

PCM ikazindikira kukokomeza kwapadera pamayendedwe oyendetsera jekeseni wochepetsera injini ya block block iwiri, block one, nambala ya P2052 idzasungidwa ndipo nyali yosonyeza kuwonongeka itha kuwunikira.

Kodi kuuma kwa DTC kumeneku ndi kotani?

Khodi yosungidwa ya P2052 iyenera kuchitidwa mozama ndipo iyenera kuchitidwa mwachangu momwe zingathere. Makina a SCR atha kukhala olumala chifukwa cha izi. Kuwonongeka kwa chothandizira kumatha kuchitika ngati zinthu zomwe zidapangitsa kuti kulimbikira kwa code sizikukonzedwa munthawi yake.

Kodi zina mwazizindikiro za code ndi ziti?

Zizindikiro za vuto la P2052 zitha kuphatikiza:

• Kuchepetsa ntchito ya injini
• Utsi wakuda kwambiri wakutha kwa galimoto
• Kuchepetsa mafuta
• Ma code ena okhudzana ndi SCR

Kodi zina mwazomwe zimayambitsa codezi ndi ziti?

Zifukwa za code iyi zitha kuphatikizira izi:

• Valavu yoyipitsa yoyipa yoyipa
• Tsegulani kapena zazifupi munthawi yochepetsera jekeseni wamagetsi
• Kusakwanira DEF mu thanki
• Wolamulira woyipa wa SCR / PCM kapena pulogalamu yolakwika

Kodi ndi njira ziti zina zothetsera P2052?

Kuti mupeze nambala ya P2052, mufunika kupeza chojambulira, digito volt / ohmmeter (DVOM), ndi gwero lazidziwitso zodziwitsa anthu 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 kudziwa kuti mwayang'ana ma harnesses ndi zolumikizira zamagetsi zotsekemera. 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 DVOM kuti muwone momwe magetsi a SCR aliri. Onetsetsani mafyuzi ndi dera lolemera kuti mupewe kuzindikira molakwika. Ngati mphamvu yolondola (batri yamagetsi) ndi ma circuits apansi apezeka, gwiritsani ntchito sikani kuti muchotse valavu yochepetsera jekeseni (solenoid) ndikuyang'ana magetsi oyendetsera dera. Ngati voteji sakukwanira, ganizirani kuti wowongolera ali ndi vuto kapena ali ndi pulogalamu yolakwika.

Ngati voliyumu yamagetsi ili mkati mwazidziwitso, gwiritsani ntchito DVOM kuyesa valavu yochepetsera yomwe ikufunsidwa. Ngati valavu sakwaniritsa zomwe wopanga amapanga, akukayikira kuti yalephera.

• Valavu yochepetsera jekeseni ndi injini yopangira mafuta okhaokha yomwe imapopera madzi m'madzi otulutsa utsi.

Zokambirana zokhudzana ndi DTC

Mukufuna thandizo lina ndi code P2052?

Ngati mukufunabe thandizo ndi DTC P2052, 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.
