P2721 Pressure Control Solenoid D Control Circuit Kulephera

Mapepala a OBD-II DTC

D Pressure Control Solenoid Control Circuit High

Kodi izi zikutanthauzanji?

Iyi ndi nambala yovuta yodziwitsa anthu za matenda opatsirana pogonana (DTC) yomwe imagwiritsidwa ntchito pamagalimoto a OBD-II omwe ali ndi zotengera zodziwikiratu. Izi zitha kuphatikizira, koma sikuchepera, magalimoto ochokera ku Ford, GMC, Chevrolet, Honda, BMW, Saturn, Land Rover, Acura, Nissan, Saturn, ndi zina zambiri. ndi masanjidwe.

Nthawi zambiri, zotumiza zokhazokha zimaphatikizira osachepera atatu opanikizika otchedwa solenoids A, B, ndi C. Kutumiza kwatsopano kumakhala ndi magiya ochulukirapo komanso ma solenoids ambiri, kukupatsani ma solenoids D, E, F, etc. E. Ma DTC angapo Amalumikizidwa ndi dera "D" loyendetsa magetsi ndipo zina mwazofala kwambiri ndi P2718, P2719, P2720 ndi P2721. DTC P2721 OBD-II ikakhazikitsidwa, gawo loyendetsa mphamvu ya powertrain (PCM) lapeza vuto pamavuto oyendetsera kuthamanga kwa "D". Makhalidwe apaderawa amachokera pazovuta zomwe zimapezeka ndi PCM.

Kutumiza kwadzidzidzi kumayang'aniridwa ndi malamba ndi zotchinga zomwe zimasuntha magiya poyika kuthamanga kwamadzi pamalo oyenera nthawi yoyenera. Ma valve oyendetsa magetsi amayendetsa magetsi kuti azitha kuyendetsa bwino komanso kusuntha kosalala. PCM imayang'anira kukakamiza mkati mwa ma solenoids ndikuwongolera madzimadzi kuma circuits osiyanasiyana amadzimadzi, omwe amasintha kuchuluka kwa kufalikira chimodzimodzi momwe amafunikira.

P2721 imayikidwa ndi PCM ikazindikira kuti "D" kuwongolera kuthamanga kwa solenoid control circuit ndikokwera motero sikugwira ntchito bwino.

Chitsanzo cha ma solenoids opatsirana:

Kodi kuuma kwa DTC kumeneku ndi kotani?

Kukula kwa code iyi nthawi zambiri kumayambira pang'ono, koma imatha kupita patsogolo kufika pamlingo waukulu ngati singakonzedwe munthawi yake. Nthawi yomwe kufalikira kumawombana ndi zida, zimatha kuyambitsa kuwonongeka kwamkati kwathunthu, ndikupangitsa kuti vutoli likhale lalikulu.

Kodi zina mwazizindikiro za code ndi ziti?

Zizindikiro za vuto la P2721 zitha kuphatikiza:

• Kuchuluka mafuta
• Yang'anani kuwala kwa injini
• Kutentha kumatentha kwambiri
• Kutumiza kumaterera mukasuntha magiya
• Bokosi lamagetsi limasunthira kwambiri (zida zimachita)
• Zizindikiro zotheka ngati moto
• PCM imayika kufalitsako mu braking mode.

Kodi zina mwazomwe zimayambitsa codezi ndi ziti?

Zifukwa zosinthira P2721 code zitha kuphatikizira izi:

• Kupunduka kwakanthawi kothana ndi mpweya
• Matenda opatsirana opatsirana
• Fyuluta yocheperako yochepa
• Wopanda kufala mpope
• Opunduka kufala vavu thupi
• Maulendo oletsedwa amadzimadzi
• Cholumikizira chowonongeka kapena chowonongeka
• Kulumikizana kolakwika kapena kowonongeka
• PCM yolakwika

Kodi ndi njira ziti zina zothetsera P2721?

Musanayambe njira yothetsera vuto lililonse, muyenera kuunikanso za Technical Service Bulletins (TSB) zamagalimoto chaka chilichonse, mtundu ndi kufalitsa. Nthawi zina, izi zimatha kukupulumutsirani nthawi yayitali ndikukulozerani njira yoyenera.

Kuwona madzimadzi ndi zingwe

Gawo loyamba ndikuwunika kuchuluka kwa madzimadzi ndikuwona momwe madzi amadzidetsa. Musanasinthe madzimadzi, muyenera (ngati kuli kotheka) onani zolembedwazo kuti muwone nthawi yomwe fyuluta ndi madzi adasinthidwa komaliza.

Izi zimatsatiridwa ndikuwunika mwatsatanetsatane kuti muwone momwe zingwe zilili ndi vuto lililonse. Chongani zolumikizira ndi kulumikizana kwa chitetezo, dzimbiri ndi kuwonongeka kwa zikhomo. Izi zikuyenera kuphatikiza zolumikizira zonse ndi zolumikizira kuma solenoids oyendetsera kuthamanga, pampu yotumiza, ndi PCM. Kutengera mtundu wakapangidwe, pampu yotumizira imatha kuyendetsedwa pamagetsi kapena pamakina.

Njira zapamwamba

Njira zowonjezerapo nthawi zonse zimakhala zogwirizana ndi magalimoto ndipo zimafunikira zida zapamwamba kuti zichitike molondola. Njirazi zimafuna zikwangwani zama digito zama multimeter komanso zamagalimoto. Nthawi zonse mumayenera kupeza zovuta zamagalimoto anu musanapite patsogolo. Zofunikira pamagetsi zimadalira mtundu wina wamagalimoto. Zovuta zamadzimadzi zimatha kusiyanasiyana kutengera kapangidwe ndi kasinthidwe ka kufalitsa.

Kupitiliza kufufuza

Pokhapokha ngati tafotokozedwapo, zazingwe zolumikizira ndi kulumikizana koyenera kuyenera kukhala 0 ohms of resistance. Kufufuza mosalekeza kuyenera kuchitidwa nthawi zonse ndi magetsi osadulidwa kuti tipewe kufupikitsa dera ndikuwononga zambiri. Kukaniza kapena kupitilira kulikonse kumawonetsa kulumikizana kolakwika komwe kumatsegulidwa kapena kufupikitsidwa ndipo kumafuna kukonzanso kapena kusintha.

Kodi njira zokhazikika zotani zokonzera code iyi ndi ziti?

• Kuchotsa madzi ndi zosefera
• Sinthanitsani chopanikizika kulamulira solenoid.
• Konzani kapena sinthani pampu yolakwika yolumikizira
• Konzani kapena sinthanitsani ndi valavu yolumikizira yolakwika
• Kutumiza kwamadzi kuti muchotse magawo 
• Kukonza zolumikizira ndi dzimbiri
• Konzani kapena sinthanitsani zingwe zolakwika
• Kung'anima kapena m'malo PCM zosalongosoka

Matenda osazindikira omwe angakhalepo angaphatikizepo:

• Vutoli la injini
• Kutumiza mpope kulephera
• Vuto lakutumiza kwamkati
• Vuto lakutumiza

Tikukhulupirira kuti zomwe zili m'nkhaniyi zingakuthandizeni kukonza P2721 Pressure Control Solenoid "D" Control Circuit Diagnostic Code (s). Nkhaniyi ndi yongofuna kudziwa zambiri komanso ma data aukadaulo agalimoto yanu azikhala patsogolo nthawi zonse.   

Zokambirana zokhudzana ndi DTC

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

Mukufuna thandizo lina ndi code P2721?

Ngati mukufunabe thandizo ndi DTC P2721, 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.
