P0746 Pressure Control Solenoid A Perf / Off

Khodi Yovuta ya OBD-II - P0746 - Kufotokozera Zaukadaulo

P0746 - Pressure control solenoid A ikuyenda kapena kukakamira.

Code P0746 imapangidwa pamene PCM imazindikira kusagwira ntchito pamagetsi amagetsi owongolera solenoid circuit.

Kodi vuto la P0746 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 P0746 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.

P0746 yakhazikitsidwa ndi PCM pomwe "A" yothana ndi mphamvu yamagetsi sikugwira ntchito bwino kapena ikadalira "Off".

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 P0746 ndi ziti?

Palibe zizindikiro zokhazikika zomwe zimachitika nthawi zonse ndi P0746. Ndipotu, madalaivala ena sanena zizindikiro zilizonse zoonekeratu. Madalaivala ena amayenera kupirira chosinthira chosinthira ma torque osachita / kusokoneza. Kukhoza kwawo kusuntha kungakhalenso kochepa kwambiri kapena ngakhale kulemala kotheratu. Injini ikangoyima kapena ikayandikira kuyimitsa, imatha kuyimitsa.

Zizindikiro za vuto la P0746 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

Ma code angapo amavuto amalumikizidwa ndi P0746. Zizindikirozi zimagwirizana ndi mavuto ndi zinthu monga torque converter clutch, shift solenoid, gear ratio, etc.

Kodi zina mwazomwe zimayambitsa codezi ndi ziti?

Zifukwa zosinthira P0746 code zitha kuphatikizira izi:

• 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
• Zolakwika zamagetsi zamagetsi zowongolera solenoid
• Mavuto amakina ndi kufala
• Kutsekeka mkati mwa njira zamafuta zopatsirana mkati
• Kutulutsa kochepa kwamadzimadzi
• Matenda opatsirana opatsirana
• Modul yolakwika yowongolera kufalitsa
• PCM yolakwika (ngakhale izi ndizochitika kawirikawiri)

Kodi ndi njira ziti zina zothetsera P0746?

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.

Kodi makaniko amazindikira bwanji code ya P0746?

Makaniko anu adzagwiritsa ntchito scanner ya OBD-II kuti adziwe ma code omwe asungidwa. Kenako adzayang'ana ngati ali ndi mphamvu pakupatsirana. Pambuyo pake, adzayang'ana madzi opatsirana kuti adziwe ngati ali ndi kachilombo (kapena kuti pakufunika zambiri). Ngati fungo lamadzimadzi litapsa, poto yopatsirana iyenera kuyang'aniridwa.

Makaniko anu adzafunanso kuyang'ana mawaya onse omwe amathandizira kuwongolera kuthamanga kwa solenoid. Zida zina zamagetsi monga zolumikizira zidzakhalanso zofunika kuyang'ana. Pampu yothamanga kwambiri iyeneranso kuyesedwa.

Zolakwa Zomwe Zimachitika Mukamazindikira Khodi P0746

Ngakhale ndikofunikira kuyang'ana, pampu yothamanga kwambiri nthawi zambiri imaimbidwa mlandu pama code onse ndipo motero imasinthidwa mwachangu popanda kusamala bwino. M'malo mwake, ma waya olakwika komanso zolakwika zowongolera zamagetsi zamagetsi ndizoyenera kukhala ndi udindo pa code P0746. Izi ziyenera kukhala chikumbutso choti munthu afufuze bwinobwino matendawo asanayambe kuchitapo kanthu.

Kodi P0746 ndi yowopsa bwanji?

Khodiyo sikutanthauza chinthu chowopsa kapena vuto lomwe lingawononge kwambiri galimoto yanu ngati silinakonzedwe nthawi yomweyo. Komabe, monga momwe mwawonera pazizindikiro zomwe zili pamwambapa, ndizotheka kuti kufalikira kwanu kumatha kutenthedwa kapena kulephera kuchitapo kanthu. Izi zitha kukhala zokwera mtengo ndipo ngakhale pang'ono zitha kubweretsa mavuto akulu kwambiri pamsewu, ndiye ndi lingaliro labwino kuthetsa vutoli mwachangu momwe mungathere.

Ndi kukonza kotani komwe kungakonze P0746?

Kukonza galimoto kungafune izi:

• Bwezerani/konza pampu yolakwika
• Sinthani mulingo wamadzimadzi otumizira
• Kusintha madzimadzi opatsirana
• Sinthani valavu yolakwika ya solenoid valve.
• Konzani kugwirizana kwa magetsi ku mzere wothamanga wa solenoid valve circuit.

Ndemanga zowonjezera zomwe muyenera kuziganizira ponena za code P0746

Popeza kachidindo kameneka kakhoza kutsagana ndi manambala ena angapo, ndikofunikira kuti muzichita nawo momwe adasungidwira kuti musaphonye chilichonse.

Mukufuna thandizo lina ndi code P0746?

Ngati mukufunabe thandizo ndi DTC P0746, 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.
