P2043 Reductant Temperature Sensor Circuit Out of Range / Performance

Mapepala a OBD-II DTC

Kuchepetsa Kuchepetsa Kutentha kwa Dongosolo Pazigawo Zosiyanasiyana

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

Khodi yosungidwa P2043 imatanthauza kuti powertrain control module (PCM) yazindikira kuchuluka kwamagetsi pamayendedwe ochepetsa kutentha. Nambala iyi imawonetsedwa pamagalimoto omwe ali ndi injini yoyera ya dizilo.

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 mu valavu yochepetsera (solenoid). Jekeseni woyenera wa DEF umakweza kutentha kwa fyuluta ndikuilola kuti igwire bwino ntchito. Imakulitsa 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 mpweya wotulutsa mpweya (komanso zolowetsa zina) kuti mudziwe nthawi yoyenera ya jekeseni ya DEF (yochepetsa). Mwatsatanetsatane jekeseni DEF chofunika kusunga utsi mpweya kutentha mkati magawo zovomerezeka ndi konza moyenera kusefera wa zoipitsa.

Pampu yochepetsera / kukonzanso imagwiritsidwa ntchito kupondereza DEF mumachitidwe amadzimadzi omwe angagwiritsidwe ntchito akafunika. PCM imayang'anira magetsi ampopu opatsirana pakusintha kosalekeza komanso kuchuluka kwa kuchuluka. PCM imayang'aniranso kachipangizo kamodzi kapena zingapo muzowonjezera zowonjezera kuti mudziwe ngati pali zotuluka m'dongosolo.

Ngati PCM iwona kuchuluka kwa voliyumu pa reductant sensor sensor circuit yomwe ili kutali, code P2043 idzasungidwa ndipo nyali yowonetsera kusagwira ntchito (MIL) ikhoza kuunikira. Kuunikira kwa MIL kungafunike kuzungulira kangapo - ngati kulephera.

Chitsanzo cha thanki yochepetsera wothandizila:

Kodi kuuma kwa DTC kumeneku ndi kotani?

Khodi yosungidwa ya P2043 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 P2043 zitha kuphatikiza:

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

Kodi zina mwazomwe zimayambitsa codezi ndi ziti?

Zifukwa za code iyi zitha kuphatikizira izi:

• Kuchepetsa kachipangizo kachipangizo kutentha zosalongosoka
• Tsegulani kapena zazifupi munthawi yoyendera pulogalamu yochepetsera kutentha
• Wolamulira woyipa wa SCR / PCM kapena pulogalamu yolakwika

Kodi ndi njira ziti zina zothetsera P2043?

Kuzindikira chikhombo cha P2043 kumafunikira sikani yodziwira, digito volt / ohmmeter (DVOM), ndi gwero lodziwitsa zagalimoto.

Mutha kugwiritsa ntchito gwero lazidziwitso zamagalimoto anu kuti mupeze Technical Service Bulletin (TSB) yomwe ikufanana ndi chaka cha galimoto yanu, kupanga ndi kutengera; komanso kusamutsidwa kwa injini, ma code osungidwa ndi zizindikilo zapezeka. Mukachipeza, chitha kukupatsirani chidziwitso chothandiza pakuzindikira.

Gwiritsani ntchito sikani (yolumikizidwa ndi chingwe chodziwira galimoto) kuti mupeze ma code onse osungidwa ndi zomwe zimayimitsidwa pazithunzi. Ndikulimbikitsidwa kuti mulembe izi musanachotsere ma code ndikuyesa kuyendetsa galimotoyo mpaka PCM itayamba kukonzekera kapena nambala yake ichotsedwe.

Ngati PCM ilowa m'malo okonzeka panthawiyi, nambala yake ndiyokhazikika ndipo imatha kukhala yovuta kwambiri kuizindikira. Poterepa, zinthu zomwe zidapangitsa kuti codeyo isungidwe zitha kufunikira kukulirakulira asanadziwe bwinobwino.

Ngati nambala yanu yakonzedweratu nthawi yomweyo, gawo lotsatira lakuzindikira lifunika kuti mufufuze gwero lazidziwitso zamagalimoto anu kuti mupeze zojambula, ma pinout, zolumikizira zolumikizira, ndi zoyeserera zamagulu.

mwatsatane 1

Gwiritsani ntchito DVOM kuyesa kuyesa kwakanthawi kocheperako malinga ndi zomwe wopanga akuchita. Zigawo zomwe zimalephera mayeso pamlingo woyenera kwambiri ziyenera kuwonedwa ngati zopanda pake.

mwatsatane 2

Ngati kutentha kocheperako kuli mkati mwazomwe zimafotokozedwera, nambala ya P2043 imasungidwa ndipo sensa yomwe ikufunsidwa ikugwira ntchito, gwiritsani ntchito DVOM kuyesa mayendedwe olowera ndi otulutsa pakati pa sensa yotentha ndi wowongolera PCM / SCR. Chotsani olamulira onse musanagwiritse ntchito DVOM poyesa.

• Zizindikiro zochepetsera kutentha nthawi zambiri zimalumikizidwa ndi sensa yolakwika kapena yolumikizidwa.

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.
