P0879 Transmission fluid pressure sensor / switch D dera kusokonekera

Mapepala a OBD-II DTC

Kutumiza Zamadzimadzi Kupanikizika / Kusintha Dera Kusagwira D

Kodi izi zikutanthauzanji?

Izi Generic Transmission / Engine DTC nthawi zambiri imagwira ntchito pamakina onse okhala ndi OBD-II, koma amapezeka kwambiri mgalimoto zina za Dodge / Chrysler / Jeep, General Motors ndi Toyota.

Makina otsekemera amadzimadzi / ma switch (TFPS) nthawi zambiri amapezeka atalumikizidwa mbali ya thupi la valavu mkati mwa kachilomboka, ngakhale kuti nthawi zina imatha kupezeka ikadayimilira m'mbali mwanyumba / nyumba yomwe.

TFPS imasinthira kuthamanga kwamagetsi kukhala chizindikiro chamagetsi cha powertrain control module (PCM) kapena module control transmission (TCM). Nthawi zambiri, PCM / TCM imadziwitsa owongolera ena omwe amagwiritsa ntchito basi yamagalimoto.

PCM / TCM imalandira chizindikiro chamagetsi ichi kuti chizindikire kuthamanga kwa magwiritsidwe kapena kusintha kwa zida kukuchitika. Nambala iyi imayikidwa ngati cholowetsachi sichikugwirizana ndi magwiridwe antchito omwe amasungidwa mu kukumbukira kwa PCM / TCM. Zitha kukhalanso chifukwa cha zovuta zamkati zamakina pakufalitsa.

P0879 nthawi zambiri imakhala vuto lamagetsi yamagetsi (dera la sensa ya TFPS), ngakhale zili momwe zalembedwera kale, nambala iyi imatha kukhazikitsidwa chifukwa cha zovuta zamakina (kutuluka mkati, ming'alu kapena mipira yoyeserera m'thupi la valavu, kutsika kwa magwiridwe antchito / kukakamizidwa mu mzere, valavu yakhazikika mu thupi la valavu). Izi siziyenera kunyalanyazidwa panthawi yamavuto, makamaka mukamakumana ndi zovuta zapakatikati.

Njira zothetsera mavuto zimatha kusiyanasiyana kutengera wopanga, mtundu wa sensa ya TFPS, ndi mitundu yamawaya.

Matenda Okhudzana Ndi Kutumiza Kwamafayilo D Zizindikiro:

• P0875 Kutumiza kachipangizo kamadzimadzi / kusintha "D"
• P0876 Transmission Fluid Pressure Sensor / Sinthani "D" Maulendo Oyendera Dera
• P0877 Kutumiza madzimadzi kuthamanga kachipangizo / kusintha "D" - dera otsika
• P0878 Kutulutsa kwamphamvu kwamadzimadzi / switch "D"

Kuuma kwa code ndi zizindikilo

Kukula kwake kumadalira dera lomwe vutolo lidachitika. Popeza itha kukhala vuto lamagetsi kapena vuto lamagetsi, PCM / TCM imatha kulipirira pamlingo winawake. Kulephera kugwira ntchito kungatanthauze kuti PCM / TCM ikusintha kusintha kosinthira poyendetsa pakompyuta.

Zizindikiro za chikhombo cha injini ya P0879 zitha kuphatikizira izi:

• Kuwala kwa cholakwika kwayatsidwa
• Sinthani kusintha kwa kusintha
• Galimoto imayamba kuyenda pagalimoto yachiwiri kapena yachitatu (yolumikizana).

zifukwa

Nthawi zambiri chifukwa chokhazikitsa nambala iyi ndi:

• Kutseguka pakadutsa siginecha ku sensor ya TFPS
• Kutalikirana kwakanthawi kochepa pamagetsi ozungulira ma siginolo kupita ku sensor ya TFPS
• Kufupikira kwakanthawi kochepa pansi pazizindikiro zamagetsi kupita ku sensor ya TFPS
• Sensa yolakwika ya TFPS - mwina
• Vuto ndi mkati Buku HIV - zotheka
• PCM yolakwika - sizingatheke (imafuna kukonzanso pambuyo pake)

Njira zowunikira ndikukonzanso

Malo oyambira nthawi zonse amayang'ana ma bulletins aukadaulo (TSB) pagalimoto yanu. Vuto lanu limatha kukhala vuto lodziwika bwino lokonzedwa ndi wopanga ndipo limatha kukupulumutsirani nthawi ndi ndalama mukamayesa kusaka.

Chitsanzo chabwino cha izi ndi chakuti ngati pangakhale zida zina zodziwika bwino zamagetsi zomwe zimayikidwa ndi P0879, kapena ngati ma code a switch switch / switch akukhazikitsidwa. Ngati ndi choncho, yambani kufufuza kaye ndi DTC yokhudzana ndi mphamvu kapena pezani ma code angapo poyamba, chifukwa izi mwina ndi zomwe zimayambitsa P0879 code.

Kenako pezani sensa ya Transmission Fluid Pressure (TFPS) / switch pa galimoto yanu. TFPS nthawi zambiri imapezeka ili pambali pa thupi la valavu mkati mwa kachilomboka, ngakhale kuti nthawi zina imatha kupezeka kuti ili mbali yazomenyera / nyumba yomwe. Mukapezeka, yang'anani zowunikira cholumikizira ndi zingwe. Fufuzani zokopa, scuffs, mawaya owonekera, mabala owotchera, kapena pulasitiki wosungunuka. Chotsani cholumikizira ndikuyang'anitsitsa malo (zitsulo) mkati mwa cholumikizacho. Onani ngati akuwoneka owotcha kapena ali ndi zobiriwira zobiriwira zosonyeza dzimbiri, makamaka ngati amamangiriridwa kunja kwa nyumba yamagiya. Ngati mukufuna kuyeretsa malo, gwiritsani ntchito zotsukira zamagetsi ndi burashi ya pulasitiki. Lolani kuti muumitse ndikupaka mafuta amagetsi pomwe matomata amakhudza.

Ngati muli ndi chida chosakira, chotsani ma DTC pamtima ndikuwona ngati P0879 ibwerera. Ngati sizili choncho, ndiye kuti vuto ndilokulumikizana.

Awa ndi malo omwe anthu ambiri amadandaula nawo, chifukwa malumikizidwe akunja omwe ali ndi vuto lakuthwa.

Ngati nambala ya P0879 ibwerera, tifunikira kuyesa sensa ya TFPS ndi ma circuits ena. Mukatsegula makiyi, tsegulani cholumikizira magetsi pama sensa a TFPS. Lumikizani mtovu wakuda kuchokera ku digito voltmeter (DVOM) pansi kapena malo otsika otsika pa cholumikizira cha TFPS chojambulira. Lumikizani chingwe chofiira kuchokera ku DVM kupita kumalo osungira ma siginolo pa cholumikizira cha TFPS chojambulira. Yatsani injini, izimitseni. Chongani specifications wopanga; voltmeter iyenera kuwerenga volts 12 kapena 5 volts. Gwiritsani ntchito malumikizowo kuti muwone ngati asintha. Ngati magetsiwo sali olondola, konzani magetsi kapena waya wapansi kapena m'malo mwa PCM / TCM.

Ngati mayeso am'mbuyomu adachita bwino, gwirizanitsani kutsogolera kwa ohmmeter kupita kumalo osungira ma siginolo pa TFPS sensa ndipo enawo amatsogolera pansi kapena malo otsikira otsika pa sensa. Chongani zomwe wopanga akufuna kuti asachite ngati sensa kuti ayese molondola kukana kukakamizidwa ngati palibe vuto lililonse. Suntha cholumikizira pa kachipangizo kamadzimadzi kapenanso kusinthana poyang'ana kukana. Ngati kuwerenga kwa ohmmeter sikudutsa, sinthani TFPS.

Ngati mayeso onse am'mbuyomu adadutsa ndikupitiliza kulandira P0879, zikuwonetsa kuti sensa ya TFPS yalephera, ngakhale PCM / TCM yolephera komanso kulumikizana kwamkati sikungathetsedwe mpaka kachipangizo ka TFPS kasinthidwe. Ngati simukudziwa, pemphani thandizo kwa katswiri wodziwa zamagalimoto. Kuti muyike bwino, PCM / TCM iyenera kukonzedwa kapena kusinthidwa kuti igwirizane ndi galimotoyo.

Zokambirana zokhudzana ndi DTC

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

Mukufuna thandizo lina ndi nambala yanu ya p0879?

Ngati mukufunabe thandizo ndi DTC P0879, 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.
