Mapepala a OBD-II DTC

Low Low mbendera kufala madzimadzi kutentha sensa dera dera B

Kodi izi zikutanthauzanji?

Izi Diagnostic Trouble Code (DTC) ndi njira yofalitsira, zomwe zikutanthauza kuti imagwira ntchito kumagalimoto okhala ndi OBD-II okhala ndi kachipangizo koziziritsa kutentha (Jeep, Ford, Nissan, Toyota, Honda, Infiniti, Acura, Jaguar, Lexus ndi tD) . Ngakhale zili ponseponse, njira zowongolera zenizeni zimatha kusiyanasiyana kutengera mtundu / kapangidwe kake.

Chojambulira cha fluid fluid (TFT) chimapereka chizindikiritso chomwe chimagwiritsidwa ntchito ndi powertrain control module (PCM) kuti izindikire malo osunthira, kuthamanga kwa mzere, ndi kuwongolera kwa torque converter clutch (TCC). Chojambuliracho chimapezeka nthawi zambiri poto yamafuta.

Chojambulira cha TFT chimalandila magetsi (makamaka ma volts 5) kuchokera ku PCM. Amasintha kulimbikira kwake kwamkati kutengera kutentha kwa madzi otumizira kuti atumize siginecha yamagetsi ku PCM. Masensa a TFT ndi mtundu wa kutentha koyefishienti koipa (NTC) thermistor. Izi zikutanthauza kuti kulimbikira kwamkati kwa sensa kumakhala kofanana ndi kutentha kwamafuta. Mphamvu yamagetsi yamagetsi ya TFT imachepa chifukwa kutentha kwamadzimadzi kumatuluka komanso mosemphanitsa.

P2742 imayikidwa PCM ikazindikira kachilombo kamene kamatulutsa kachipangizo kamene kamafotokozera kuti "B". Izi nthawi zambiri zimawonetsa kanthawi kochepa mu dera. Funsani buku lopangira makina anu kuti mudziwe dera lomwe lili "B" pagalimoto yanu.

Chitsanzo cha kachipangizo kamadzimadzi kotentha:

Kufanana Kofikira Chamadzimadzi Kutentha SENSOR "B" manambala azigawo:

• P2740 Kutumiza Chamadzimadzi Kutentha SENSor B Kusayenda Kwadongosolo
• P2741 Kutumiza Chamadzimadzi Kutentha SENSOR B Maulendo Ozungulira / Magwiridwe
• P2743 Kutumiza Kwambiri Kutentha Kwamadzimadzi Kutentha B Circuit
• P2744 Transmission Fluid Kutentha SENSOR Kulephera

Kuuma kwa code ndi zizindikilo

Kuvuta kwa code iyi ndikwapakati mpaka kukhwima. Nthawi zina, code iyi ikhoza kuwonetsa vuto lopatsirana. Ndikoyenera kukonza code iyi posachedwa.

Zizindikiro za chikhombo cha injini ya P2742 zitha kuphatikizira izi:

• Nyali yochenjeza injini imabwera
• Ntchito yolakwika ya cholembera cha torque
• Kusintha mwamphamvu kapena kuchedwa
• Galimoto idakhazikika pamapeto pake

zifukwa

Zomwe zimayambitsa DTC iyi zitha kuphatikiza:

• Cholakwika kufala kachipangizo kutentha madzimadzi
• Matenda opatsirana
• Mavuto a zingwe
• PCM yolakwika

Njira zowunikira ndikukonzanso

Yambani poyang'ana poyang'ana kachilombo kamene kamatulutsa kutentha kwa madzi ndi zingwe zogwirizana. Fufuzani malumikizidwe otayirira, zingwe zowonongeka, ndi zina zambiri. Ngati kuwonongeka kukupezeka, konzani momwe zingafunikire, chotsani nambalayo kuti muwone ngati ingabwererenso. Kenako yang'anani ma bulletins aukadaulo (TSBs) zavutolo. Ngati palibe chomwe chikupezeka, muyenera kupitilira pakuwunika pang'onopang'ono.

Otsatirawa ndi njira yodziwika bwino popeza kuyesa kwa nambala iyi kumasiyana ndi galimoto ndi galimoto. Kuti muyesetse bwino dongosololi, muyenera kuyang'ana pa chojambula chojambula cha wopanga.

Yesetsani kuyesa dera

Gwiritsani ntchito chida chojambulira kuti muwone momwe kachidindo kamatengera kachilomboka. Chotsani kachipangizo cha TFT; mtengo wogwiritsa ntchito scan uyenera kutsikira pamtengo wotsika kwambiri. Kenako lumikizani jumper kudutsa malo. Ngati chida chosakira chikuwonetsa kutentha kwambiri, malumikizowo ndi abwino ndipo ECM imatha kuzindikira kulowetsa. Izi zikutanthauza kuti vuto limakhudzana kwambiri ndi sensa osati dera kapena PCM.

Chongani kachipangizo

Chotsani cholumikizira cholumikizira kutentha kwa madzi. Kenaka yesani kutsutsana pakati pa malo awiri a sensa ndi DMM yoikidwa ku ohms. Yambitsani injini ndikuwona mtengo wake; mikhalidwe iyenera kuchepa pang'onopang'ono injini ikayamba kutentha (onetsetsani kutentha kwa injini pa dashboard kuti muwonetsetse kuti injini ikugwira ntchito). Ngati kutentha kwa injini kumakwera koma kulimbana kwa TFT sikuchepera, sensa ndiyolakwika ndipo imayenera kusinthidwa.

Fufuzani dera

Fufuzani mbali yamagetsi yamagawo a dera: poyatsira, gwiritsani ntchito digito yama digito yoyambira volts kuti muwone mphamvu zamagetsi zamagetsi za 5V kuchokera ku PCM pamalo amodzi amagetsi a TCM. Ngati palibe chizindikiro cholozera, polumikiza mita yoyikidwa ku Ohm (ndikuzimitsa) pakati pa malo ogwiritsira ntchito TFT ndi PCM. Ngati kuwerengera mita sikulekerera (OL), pali dera lotseguka pakati pa PCM ndi sensa yomwe imayenera kupezeka ndikukonzedwa. Ngati kauntala akuwerenga mtengo, pali kupitiriza.

Ngati zonse zili bwino mpaka pano, mudzafunika kuwona ngati ma volts asanu akutuluka mu PCM pamalo opangira magetsi. Ngati palibe 5V voltage voltage yochokera ku PCM, PCM mwina ndi yolakwika.

Fufuzani malo oyendera dera.

Lumikizani mita yotsutsa (kuwotcha OFF) pakati pa malo otsetsereka pansi pa sensa ya kutentha kwa madzi ndi malo otsetsereka pa PCM. Ngati kuwerengera kwa mita kulibe kulekerera (OL), pali dera lotseguka pakati pa PCM ndi sensa yomwe imayenera kupezeka ndikukonzedwa. Ngati kauntala ikuwerenga nambala, pali kupitiliza. Pomaliza, onetsetsani kuti PCM yakhazikika bwino polumikiza mita imodzi ku terminal ya PCM ndi ina ku chassis. Apanso, ngati mita ikuwerengera (OL), pali dera lotseguka pakati pa PCM ndi nthaka yomwe imayenera kupezeka ndi kukonzedwa.

Ngati zonse zomwe zili muntolo zayang'aniridwa, pakhoza kukhala vuto pakufalitsa. Izi ndizowona makamaka ngati maukonde opatsirana amadzimadzi amalumikizidwa molumikizana ndi njira zina zotumizira.

Zokambirana zokhudzana ndi DTC

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

Mukufuna thandizo lina ndi nambala yanu ya p2742?

Ngati mukufunabe thandizo ndi DTC P2742, 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.
