P2749 Wapakati Shaft Speed ​​Speed ​​Sensor C Dera

P2749 Wapakati Shaft Speed ​​Speed ​​Sensor C Dera

Mapepala a OBD-II DTC

Wapakatikati kutsinde Liwiro SENSOR C Dera

Kodi izi zikutanthauzanji?

Iyi ndi generic Diagnostic Trouble Code (DTC) ndipo imagwiritsidwa ntchito kwambiri pamagalimoto a OBD-II omwe amangotumiza. Izi zitha kuphatikizira koma sizochepera ku Mazda, Toyota, Chrysler, Ford, VW, Dodge, Jeep, Mercedes, Lexus, Chevrolet, ndi zina zambiri.

Ngakhale ndizazonse, njira zowongolera zenizeni zimatha kusiyanasiyana kutengera mtundu wachitsanzo, kapangidwe, kapangidwe kake, ndi kasinthidwe kakutumizirana.

Countershaft, yomwe imadziwikanso kuti countershaft, imathandizira kugawa mphamvu yozungulira kuchokera pagalimoto yolowera mpaka kutsinde komwe kumatulutsa mkati. Kuthamanga kwa countershaft kumadalira kuti muli ndi zida ziti. Pakufalitsa pamanja, izi zimalamulidwa ndi chosankhira magiya, chifukwa chake palibe chifukwa chowongolera kuthamanga kwapakati.

Kumbali ina, potengera zodziwikiratu, ngati muli mumayendedwe a "D", zida zomwe muli zimatsimikizika ndi TCM (module control control) pogwiritsa ntchito zolowetsa zingapo zomwe zimathandizira kusintha kosavuta kwamagiya. Chimodzi mwama sensa ophatikizidwa pano ndi chojambulira cha liwiro la countershaft. TCM imafunikira izi kuti zithandizire kuzindikira ndikusintha ma hydraulic, kusintha kosintha, ndi mawonekedwe. Zomwe mungapeze pakuzindikira mitundu ina yama sensa othamanga (mwachitsanzo: VSS (mota speed sensor), ESS (engine speed sensor), ndi zina) zingakuthandizeni ndi izi, chifukwa masensa othamanga kwambiri amafanana pakupanga.

ECM (Engine Control Module) molumikizana ndi TCM (Transmission Control Module) itha kuyambitsa P2749 ndi ma code ena ofanana (P2750, P2751, P2752) akawunika momwe ntchito ikuyendera mu shaft speed shaft kapena maseketi. Nthawi zina, sensa ikalephera, TCM imagwiritsa ntchito masensa ena othamanga potumiza ndikuwonetsa "hayidiroliki" kukakamiza kwa hydraulic kuti mayendedwe azitha kugwira ntchito, koma izi zimatha kusiyanasiyana pakati pa opanga.

Code P2749 Intermediate Shaft C Speed ​​Sensor Circuit imayikidwa ndi ECM (Engine Control Module) ndi / kapena TCM (Transmission Control Module) akawona kuwonongeka konse mu C speed sensor kapena dera lake. Onaninso buku lanulo lokonza magalimoto kuti mudziwe gawo lomwe lili pa "C" loyenera kugwiritsa ntchito.

ZINDIKIRANI. Lembani manambala amawu aliwonse omwe angagwiritsidwe ntchito ngati magetsi oyatsa angapo ayatsidwa (mwachitsanzo, kuwongolera, ABS, VSC, ndi zina zambiri).

Chithunzi chojambulira liwiro:

Kodi kuuma kwa DTC kumeneku ndi kotani?

Ndinganene cholakwika ichi ndi chachikulu kwambiri. Monga tanena kale, kufalitsa kwanu kodziwikiratu kungakhale kukuyenda bwino. Komabe, zitha kukhalanso chizindikiro ngati pali vuto limodzi kapena zingapo zazikulu. Njira yabwino ndikuzindikira vuto lililonse lopatsirana mwachangu momwe mungathere.

Kodi zina mwazizindikiro za code ndi ziti?

Zizindikiro za vuto la P2749 zitha kuphatikiza:

• Kusintha kwa zida zolimba
• Zizindikiro zingapo zadashboard zimawunikira
• Kusasamalira bwino
• Kuthamanga kwa injini kosakhazikika

Kodi zina mwazomwe zimayambitsa codezi ndi ziti?

Zifukwa zamtundu wa injini iyi P2749 zitha kuphatikizira izi:

• Wopunduka kapena wowonongeka wapakati shaft sensor
• Mavuto amagetsi pamawaya pakati pa sensa yothamanga ndi ma module omwe agwiritsidwa ntchito
• Vuto lamkati ndi ECM ndi / kapena TCM
• Masensa ena okhudzana / ma solenoids awonongeka kapena olakwika (mwachitsanzo: kulowetsa shaft liwiro, zotulutsa shaft sensor, solenoid, etc.)
• Kutulutsa madzi akumwa kapena otsika (ATF)

Kodi ndi njira ziti zina zothetsera P2749?

Mukasanthula nambala iyi, ndikuganiza kuti mwawona kale kuchuluka kwa madzimadzi. Ngati sichoncho, yambani ndi izi. Onetsetsani kuti madziwo ndi oyera komanso odzaza bwino. Madzi akangokhala bwino, muyenera kupeza malo othamangitsira liwiro. Nthawi zambiri masensa awa amaikidwa mwachindunji panyumba yotumizira.

Mutha kulumikizanso sensa pansi pa hood, izi zitha kuphatikizira kuchotsa chinthu china monga choyeretsa mpweya ndi bokosi, mabakiteriya osiyanasiyana, mawaya, ndi zina zambiri kuti mupeze mwayi. Onetsetsani kuti sensa ndi cholumikizira chokhudzana nacho chili bwino komanso chikugwirizana.

MFUNDO: Kutentha kwa ATF (komwe kumatulutsa madzi amadzimadzi) omwe amanunkhiza ngati madzi atsopano ndikofunikira, chifukwa chake musawope kuchita zonse zotumizira ndi zosefera zonse, ma gaskets, ndi madzi.

Chojambulira chothamanga mosavuta chikuyenera kuchotsedwa ndikuyeretsedwa. Palibe chilichonse, ndipo mukawona kuti sensa ndi yakuda kwambiri mukachotsa, mutha kutsuka mavuto anu. Gwiritsani ntchito zotsukira mabuleki ndi chiguduli kuti sensa ikhale yoyera. Dothi ndi / kapena kumeta kumatha kukhudza kuwerenga kwa masensa, chifukwa chake onetsetsani kuti sensa yanu ndi yoyera!

ZINDIKIRANI. Chizindikiro chilichonse chotsutsana pa sensa chitha kuwonetsa kutalika kokwanira pakati pa mphete ndi chojambulira. Mosakayikira sensa ndi yolakwika ndipo tsopano ikugunda mphete. Ngati chojambulira sichikutsuka mpheteyo, onaninso njira zopangira kuti musinthe mawonekedwe a sensa.

Onani sensor ndi kuzungulira kwake. Kuti muyese sensa yokhayo, muyenera kugwiritsa ntchito ma multimeter ndi zomwe wopanga amapanga ndikuyesa mitundu yosiyanasiyana yamagetsi pakati pa zikhomo za sensor. Chinyengo chimodzi chabwino ndikuyesa mayesowa kuchokera pamawaya omwewo, koma pazikhomo zoyenera pa cholumikizira cha ECM kapena TCM. Izi ziwunika kukhulupirika kwa lamba wapampando womwe ukugwiritsidwa ntchito komanso sensor.

Zokambirana zokhudzana ndi DTC

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

Mukufuna thandizo lina ndi code P2749?

Ngati mukufunabe thandizo ndi DTC P2749, 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.
