P0748 Valavu yamagetsi yamagetsi yamagetsi yamagetsi

Khodi Yovuta ya OBD-II - P0748 - Kufotokozera Zaukadaulo

P0748 - Pressure control solenoid valve A, magetsi.

Khodi iyi imayimira Electric Pressure Control Solenoid. Khodi iyi ikhoza kukhala ndi matanthauzidwe osiyanasiyana amtundu wagalimoto, choncho onetsetsani kuti mwayang'ana ma code agalimoto yanu.

Kodi vuto la P0748 limatanthauza chiyani?

Iyi ndi generic Transmission Diagnostic Trouble Code (DTC) ndipo imagwiritsidwa ntchito kwambiri pamagalimoto a OBD-II okhala ndi zotengera zodziwikiratu.

Izi zingaphatikizepo, koma sizingokhala ku, Ford, Mercury, Lincoln, Jaguar, Chevrolet, Toyota, Nissan, Allison / Duramax, Dodge, Jeep, Honda, Acura, ndi zina zambiri. chaka. , kupanga, mtundu ndi zida zamagetsi zamagetsi.

Pamene P0748 OBD-II DTC wakhazikitsidwa, powertrain control module (PCM) anapeza vuto ndi kufala kuthamanga ulamuliro solenoid "A". Zotumiza zambiri zodziwikiratu zimakhala ndi solenoid zosachepera zitatu, zomwe ndi solenoids A, B, ndi C. Zizindikiro zamavuto zomwe zimagwirizanitsidwa ndi solenoid "A" ndi P0745, P0746, P0747, P0748, ndi P0749. Kuyika kwa code kumatengera vuto linalake lomwe limachenjeza PCM ndikuyatsa kuwala kwa injini.

Mphamvu zamagetsi zamagetsi zamagetsi zimayang'anira kuthamanga kwa madzimadzi kuti zizigwira bwino ntchito. PCM imalandira chizindikiritso chamagetsi kutengera kuthamanga mkati mwa ma solenoids. Kutumiza kwadzidzidzi kumayang'aniridwa ndi malamba ndi zotchinga zomwe zimasuntha magiya poyika kuthamanga kwamadzi pamalo oyenera nthawi yoyenera. Kutengera ndi zizindikilo zochokera pazida zoyendetsera kuthamanga kwamagalimoto, PCM imayang'anira ma solenoids opanikizika kuti atsogolere madzimadzi molingana ndi madera osiyanasiyana amadzimadzi omwe amasintha kuchuluka kwakanthawi nthawi yoyenera.

P0748 yakhazikitsidwa ndi PCM pomwe "A" yothana ndi vuto lamavuto ikumana ndi vuto lamagetsi.

Chitsanzo cha mphamvu yothanirana pamagetsi:

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.

Kodi zizindikiro za P0748 ndi ziti?

Ngati khodiyi yasungidwa, simungazindikire zizindikiro zoonekeratu, kapena mungazindikire zovuta zosintha, monga kusasunthika konse. Injini ikhoza kuyimilira popanda ntchito, kusintha kwa magiya kungakhale kovutirapo kapena kuterera, ndipo kutumizira kumatha kutenthedwa. Zizindikiro zina zikuphatikiza kuchepa kwamafuta amafuta komanso nyali yowunikira (MIL) yoyaka. Ma code ena akhoza kukhazikitsidwa, monga okhudzana ndi gear ratio, shift solenoid, kapena transmission slip.

Zizindikiro za vuto la P0748 zitha kuphatikiza:

• Galimoto imalowa munjira zadzidzidzi
• Kutumiza kumaterera mukasuntha magiya
• Kutentha kwa kufala
• Kufala kumayikidwa mu zida
• Kuchepetsa mafuta
• Zizindikiro zotheka ngati moto
• Chowunikira cha Injini chayatsa

Kodi zina mwazomwe zimayambitsa codezi ndi ziti?

The pressure control solenoid valve ikhoza kulephera ngati pali zotsatirazi:

• Madzi opatsirana oipitsidwa kapena odetsedwa
• Madzi okhala ndi zotulutsa zochepa
• Kutsekeka kwa hydraulic m'magawo amadzimadzi opatsirana
• Valavu yoyipa yamagetsi yoletsa kuthamanga kwamagetsi
• Zolakwika zamakina zamakina mkati
• Cholakwika TCM (Transmission Control Module)
• PCM yowonongeka (yosowa)
• Kupunduka kwakanthawi kothana ndi mpweya
• Madzi onyansa kapena owonongeka
• Fyuluta yakuda kapena yotseka
• Wopanda kufala mpope
• Opunduka kufala vavu thupi
• Maulendo ochepa amadzimadzi
• Cholumikizira chowonongeka kapena chowonongeka
• Kulumikizana kolakwika kapena kowonongeka
• PCM yolakwika

Kodi ndi njira ziti zina zothetsera P0748?

Musanayambe njira yothetsera vuto lililonse, muyenera kuunikanso za Technical Service Bulletin (TSB) zamagalimoto pachaka, mtundu ndi kufalitsa. Nthawi zina, izi zimatha kukupulumutsirani nthawi yayitali ndikukulozerani njira yoyenera. Muyeneranso kuwunika zolembedwa zamagalimoto kuti muwone ngati fyuluta ndi madzimadzi zidasinthidwa komaliza, ngati zingatheke.

Kuwona madzimadzi ndi zingwe

Gawo loyamba ndikuwunika kuchuluka kwa madzimadzi ndikuwona momwe madzi amadzidetsa. Musanasinthe madzimadzi, muyenera kuyang'ana zomwe zalembedwa pagalimoto kuti mudziwe nthawi yomwe fyuluta ndi madzimadzi 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. Pampu yotumizira imatha kuyendetsedwa pamagetsi kapena pamakina, kutengera kasinthidwe.

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. Muyenera kulandira malangizo osakira za galimoto yanu musanapite patsogolo. Zofunikira pamagetsi zimatha kusiyanasiyana kutengera mtundu wamagalimoto kupita pagalimoto. Zovuta zamadzimadzi zimasiyananso kutengera kapangidwe ka kapangidwe kake ndi kasinthidwe kake.

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
• Kutulutsa kothamanga kwa magawo oyera
• Kukonza zolumikizira ndi dzimbiri
• Kukonza kapena m'malo mwa zingwe
• Kuwala kapena kusintha PCM

Matenda osazindikira omwe angakhalepo angaphatikizepo:

• Vutoli la injini
• Vuto lotulutsa pampu
• Vuto lakutumiza kwamkati
• Vuto lakutumiza

Tikukhulupirira kuti zomwe zalembedwa m'nkhaniyi zakuthandizani kukulozerani njira yoyenera yothetsera vuto lanu lothetsera vuto la DTC. Nkhaniyi ndi yongofuna kudziwa zambiri komanso ma data aukadaulo a galimoto yanu ayenera kukhala patsogolo nthawi zonse.

ZOPHUNZITSA ZAMBIRI PAMENE AMADZIWA KODI P0748

Nthawi zambiri kulephera kumeneku kumanenedwa kuti ndi vuto lamoto mu injini kapena pampu yothamanga kwambiri imatengedwa kuti ndiyomwe yachititsa. Mawaya ndi madera ena omwe akukhudzidwa akhoza kunyalanyazidwa ngati zomwe zingatheke. Ndikofunika kuonetsetsa kuti njira yonse yodziwira matenda ikuchitika.

KODI P0748 NDI YOYAMBA BWANJI?

Mavuto opatsirana ayenera kuthetsedwa nthawi zonse. Ngakhale ngati vutoli silinapitirire mpaka pamene kulephera kwa makina amkati kwachitika, zizindikiro zoyamba zimatanthauza kuti pali vuto lomwe lingakhale lalikulu m'kanthawi kochepa kwambiri.

KODI KUKONZA KODI KUUNGAKONZE KODI P0748)?

Zokonza zotheka pa code yolakwikayi ndi:

• Kukonza mabwalo owongolera kuthamanga monga mawaya ndi zolumikizira
• Pressure Regulator Solenoid Replacement
• M'malo mwa electronic pressure regulator
• Kubwezeretsa kapena kusintha bokosi lonse la gear, kuphatikiza chosinthira ma torque.
• Kutsuka ndi kusintha madzimadzi opatsirana
• Kusintha kwa TSM

NDANI ZOWONJEZERA PA KODI P0748 KUGANIZIRA

Kuyang'ana momwe mafuta otumizira alili ndi gawo lofunikira pakuthana ndi vuto. Ngati madziwa akuwoneka kapena akununkhiza atapsa, kapena ali ndi mtundu wakuda, wosawoneka bwino, galimotoyo imakhala yotsika kwambiri. Izi zikutanthauza kuti kuwonongeka kwakukulu kwamkati kungakhale kale kuchitika.

Ngakhale kuti mbali zina za njira yodziwira matenda zingathe kuchitidwa kunyumba, monga B. Transmission fluid assessment (ngati muli ndi dipstick). Ndi bwino kukaonana ndi katswiri oyenerera mwamsanga.

Mukufuna thandizo lina ndi code P0748?

Ngati mukufunabe thandizo ndi DTC P0748, 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.
