OBD-II DTC Cov Ntaub Ntawv

Intermediate Ncej Ceev Sensor C Circuit

Qhov no txhais li cas?

Qhov no yog cov teeb meem kuaj mob ib txwm muaj (DTC) thiab feem ntau siv rau OBD-II cov tsheb nrog kev siv lub tshuab tsis siv neeg. Qhov no yuav suav nrog tab sis tsis txwv rau Mazda, Toyota, Chrysler, Ford, VW, Dodge, Jeep, Mercedes, Lexus, Chevrolet, thiab lwm yam.

Txawm hais tias dav dav, cov txheej txheem kho kom raug yuav txawv nyob ntawm tus qauv xyoo, ua, qauv, thiab kev teeb tsa xa tawm.

Lub countershaft, tseem hu ua lub countershaft, pab faib lub zog sib hloov los ntawm cov tswv yim tsav mus rau lub zog tso tawm sab hauv kev sib kis. Kev ceev ceev ntawm lub cav nyob ntawm seb koj nyob qhov twg. Hauv phau ntawv xa mus, qhov no tau hais los ntawm tus xaiv lub iav, yog li tsis tas yuav tsum tswj lub nrawm nrawm.

Ntawm qhov tod tes, hauv kev siv lub tshuab tsis siv neeg, yog tias koj nyob hauv "D" tsav hom, lub iav koj nyob hauv yog txiav txim siab los ntawm TCM (kev xa xov tswj module) siv ntau lub tswv yim nkag mus uas ua rau hloov pauv tau yooj yim thiab muaj txiaj ntsig. Ib qho ntawm cov sensors suav nrog ntawm no yog lub countershaft speed sensor. TCM xav tau cov lus qhia tshwj xeeb no los pab txheeb xyuas thiab hloov kho hydraulic siab, hloov pauv cov ntsiab lus, thiab cov qauv. Kev paub txog kev txheeb xyuas lwm hom kev ntsuas nrawm (piv txwv li: VSS (lub tsheb ntsuas lub ntsuas hluav taws xob), ESS (lub cav ntsuas lub cav), thiab lwm yam) yuav pab koj nrog qhov no, vim tias feem ntau cov ntsuas qhov ntsuas tau zoo sib xws hauv kev tsim.

ECM (Kev Tswj Lub Cav) ua ke nrog TCM (Kev Tswj Kev Xa Mus) tuaj yeem qhib P2749 thiab cov lej muaj feem cuam tshuam (P2750, P2751, P2752) thaum lawv saib xyuas qhov ua haujlwm tsis raug ntawm qhov nruab nrab ntawm qhov ntsuas nrawm lossis lub voj voos. Qee zaum, thaum lub ntsuas tsis ua tiav, TCM siv lwm qhov ntsuas nrawm hauv kev xa thiab txiav txim siab "thaub qab" hydraulic siab kom ua haujlwm tsis siv neeg kis tau tus mob, tab sis qhov no tuaj yeem sib txawv ntawm cov tuam ntxhab.

Code P2749 Intermediate Shaft C Speed ​​​​Sensor Circuit Court yog teem los ntawm ECM (Engine Control Module) thiab / los yog TCM (Transmission Control Module) thaum nws / lawv saib xyuas qhov ua haujlwm tsis zoo hauv C ceev sensor lossis nws cov circuit. Nrog koj phau ntawv kho tsheb tshwj xeeb los txiav txim seb qhov twg ntawm "C" saw hlau tsim nyog rau koj daim ntawv thov tshwj xeeb.

NCO TSEG. Ua ib qho kev ceeb toom ntawm txhua tus lej ua haujlwm hauv lwm lub tshuab yog muaj ntau lub teeb ceeb toom nyob (piv txwv li kev tswj tsheb, ABS, VSC, thiab lwm yam).

Kev xa duab nrawm duab yees duab:

Dab tsi yog qhov hnyav ntawm DTC no?

Kuv xav hais tias qhov yuam kev no yog me ntsis hnyav. Raws li tau hais ua ntej, koj qhov kev sib kis tsis siv neeg tuaj yeem ua haujlwm zoo. Txawm li cas los xij, nws kuj tuaj yeem qhia tau yog tias muaj ib lossis ntau qhov teeb meem loj. Lub tswv yim zoo tshaj plaws yog txhawm rau txheeb xyuas cov teeb meem sib kis sai li sai tau.

Cov tsos mob ntawm txoj cai yog dab tsi?

Cov tsos mob ntawm P2749 teeb meem chaws yuav suav nrog:

• Nyuaj iav hloov
• Ntau lub dashboard ntsuas pom teeb
• Kev tuav tsis zoo
• Lub cav tsis ruaj khov

Dab tsi yog qee qhov ua rau pom cov cai?

Yog vim li cas rau qhov P2749 cav code yuav suav nrog:

• Puas los yog puas nruab nrab ncej ceev sensor
• Kev txhaum hluav taws xob hauv cov xov hlau ntawm qhov ntsuas qhov nrawm thiab cov qauv siv
• Teeb meem sab hauv nrog ECM thiab / lossis TCM
• Lwm yam cuam tshuam txog kev ntsuas / solenoids raug puas lossis puas ntsoog (piv txwv li: cov tswv yim nkag ceev sensor, cov zis tawm sensor, hloov solenoid, thiab lwm yam)
• Qias neeg los yog tsis siv neeg kis tau tus mob kua (ATF)

Dab tsi yog P2749 cov kauj ruam daws teeb meem?

Kauj ruam yooj yim # 1

Yog tias koj tshawb fawb cov cai no, Kuv yuav xav tias koj twb tau tshuaj xyuas cov qib dej sib kis. Yog tsis yog, pib nrog qhov no. Xyuas kom cov kua huv thiab tau ntim kom raug. Thaum cov kua dej zoo lawm, koj yuav tsum nrhiav lub countershaft speed sensor. Feem ntau cov ntsuas no tau teeb tsa ncaj qha ntawm lub tsev sib kis.

Koj tseem tuaj yeem nkag mus rau lub ntsuas hluav taws xob los ntawm hauv qab lub hood, qhov no tuaj yeem cuam tshuam nrog tshem tawm lwm cov khoom siv xws li lub tshuab nqus cua thiab lub thawv, ntau yam nkhaus, xov hlau, thiab lwm yam kom tau txais kev nkag mus. Xyuas kom tseeb tias lub sensor thiab cov txuas txuas tau zoo thiab muaj kev sib txuas tag nrho.

TSWV YIM: Burnt ATF (tsis siv neeg kis tau tus mob kua) uas tsis hnov ​​tsw zoo li cov kua tshiab xav tau, yog li tsis txhob ntshai ua qhov kev pabcuam xa mus tas li nrog txhua lub lim dej tshiab, roj av, thiab kua.

Kauj ruam yooj yim # 2

Qhov ntsuas tau yooj yim nkag tau yooj yim yuav tsum raug tshem tawm thiab ntxuav. Nws raug nqi nyob ib sab tsis muaj dab tsi, thiab yog tias koj pom tias lub ntsuas pa tau qias neeg dhau tom qab raug tshem tawm, koj tuaj yeem tshem tawm koj cov teeb meem. Siv lub tshuab nqus tsev thiab cov ntaub qhwv kom lub sensor huv. Cov av thiab / lossis cov plaub hau tuaj yeem cuam tshuam rau kev nyeem ntawv ntawm lub ntsuas cua, yog li ua kom koj lub sensor huv si!

NCO TSEG. Ib qho kos npe ntawm kev sib txhuam ntawm lub sensor tuaj yeem qhia txog qhov tsis txaus nyob nruab nrab ntawm lub nplhaib reactor thiab lub sensor. Feem ntau yuav ua rau lub sensor tsis raug thiab tam sim no tsoo lub nplhaib. Yog tias lub ntsuas ntsuas hloov pauv tseem tsis tau ntxuav lub nplhaib, xa mus rau cov txheej txheem tsim khoom los kho qhov ntsuas / qhov sib txawv ntawm cov tshuaj tiv thaiv.

Kauj ruam yooj yim # 3

Tshawb xyuas lub sensor thiab nws lub voj voog. Txhawm rau kuaj lub sensor nws tus kheej, koj yuav tsum tau siv lub multimeter thiab cov chaw tsim khoom tshwj xeeb thiab ntsuas ntau yam khoom siv hluav taws xob nruab nrab ntawm lub sensor tus pins. Ib qho ua kom yuam kev zoo yog khiav cov kev sim no los ntawm tib cov xov hlau, tab sis ntawm cov pins tsim nyog ntawm ECM lossis TCM connector. Qhov no yuav xyuas qhov tseeb ntawm lub rooj zaum siv nrog rau lub sensor.
