P0746 Siab Tswj Solenoid Ib Perf / Off

OBD-II Teeb meem Code - P0746 ​​​​- Kev piav qhia

P0746 - Kev tswj siab ntawm solenoid A yog khiav lossis daig.

Code P0746 yog tsim thaum PCM pom qhov ua haujlwm tsis zoo hauv hluav taws xob tswj hluav taws xob solenoid circuit.

Qhov teeb meem code P0746 txhais li cas?

Nov yog qhov xwm txheej kis kab mob kuaj pom tsis zoo (DTC) thiab feem ntau siv rau OBD-II cov tsheb nruab nrog lub tshuab tsis siv neeg.

Qhov no yuav suav nrog, tab sis tsis txwv rau, Ford, Mercury, Lincoln, Jaguar, Chevrolet, Toyota, Nissan, Allison / Duramax, Dodge, Jeep, Honda, Acura, thiab lwm yam. xyoo. , ua, qauv thiab khoom siv ntawm chav fais fab.

Thaum lub P0746 OBD-II DTC tau teeb tsa, lub powertrain tswj module (PCM) tau kuaj pom muaj teeb meem nrog kev sib txuas lus siab tswj solenoid "A". Feem ntau tsis siv neeg kis tau tus mob tsawg kawg yog peb lub solenoids, uas yog solenoids A, B, thiab C. Teeb meem cov lej cuam tshuam nrog solenoid "A" yog P0745, P0746, P0747, P0748, thiab P0749. Cov txheej txheem yog raws li qhov ua txhaum tshwj xeeb uas ceeb toom rau PCM thiab tig rau lub teeb pom kev ntawm lub cav.

Kev xa xov siab tswj solenoid li qub tswj cov dej kom zoo rau kev ua haujlwm tsis siv neeg. PCM tau txais lub teeb liab hluav taws xob raws li lub siab sab hauv solenoids. Kev siv lub tshuab tsis siv neeg yog tswj los ntawm koj cov menyuam thiab cov clutches uas hloov lub zog los ntawm kev siv cov kua dej mus rau qhov chaw raug yog lub sijhawm. Raws li cov cim qhia los ntawm cov khoom siv tswj lub tsheb nrawm, PCM tswj lub siab solenoids kom ncaj cov kua ntawm qhov tsim nyog siab mus rau ntau yam kev sib txuas hydraulic uas hloov pauv qhov sib kis ntawm lub sijhawm.

P0746 tau teeb tsa los ntawm PCM thaum "A" kev tswj siab solenoid tsis ua haujlwm zoo lossis raug kaw hauv "Off" txoj haujlwm.

Piv txwv ntawm kev xa xov siab tswj solenoid:

Dab tsi yog qhov hnyav ntawm DTC no?

Qhov hnyav ntawm cov cai no feem ntau pib ntawm qhov nruab nrab, tab sis tuaj yeem nrawm nrawm mus rau qib hnyav dua yog tias tsis kho raws sijhawm.

Dab tsi yog qee cov tsos mob ntawm tus lej P0746?

Tsis muaj cov tsos mob tshwm sim uas ib txwm tshwm sim nrog P0746. Qhov tseeb, qee tus neeg tsav tsheb tsis qhia cov tsos mob tshwm sim txhua. Lwm tus neeg tsav tsheb yuav tsum tau muab tso nrog lub torque converter clutch tsis koom / disengaging. Lawv lub peev xwm txav mus los kuj tuaj yeem raug txwv hnyav lossis txawm tias xiam oob qhab. Thaum lub cav tsis ua haujlwm lossis ze rau qhov nres, nws tuaj yeem nres.

Cov tsos mob ntawm P0746 teeb meem chaws yuav suav nrog:

• Lub tsheb mus rau hom xwm txheej ceev
• Kev kis kab mob hla thaum hloov lub zog
• Kub dhau ntawm kev sib kis
• Kev kis kab mob hauv iav
• Txo roj kev lag luam
• Tej zaum cov tsos mob zoo li hluav taws
• Tshawb xyuas lub teeb lub teeb

Ib tug xov tooj ntawm lwm yam teeb meem code yog txuam nrog P0746. Cov lis dej num no muaj feem xyuam rau cov teeb meem nrog rau tej yam xws li lub torque converter clutch, hloov solenoid, iav piv, thiab lwm yam.

Dab tsi yog qee qhov ua rau pom cov cai?

Yog vim li cas rau qhov P0746 hloov chaws yuav suav nrog:

• Ua tsis zoo siab tswj solenoid
• Dej qias neeg los yog muaj kuab paug
• Qhuav lossis txhaws lim lim
• Cov twj tso kua mis tsis zoo
• Lub cev tsis zoo kis lub cev
• Txwv cov ntawv hla dhau
• Corroded lossis puas txuas
• Cov kab tsis zoo lossis puas
• Tsis zoo PCM
• Faulty electronic pressure tswj solenoid
• Mechanical teeb meem nrog kev sib kis
• Thaiv nyob rau hauv cov roj raws ntawm lub internal kis tau tus mob
• Tsawg kis tau kua theem
• Cov kab mob kis tau tus kab mob
• Faulty kis tau tus mob tswj module
• Faulty PCM (txawm tias qhov no yog qhov tshwm sim tsawg heev)

Dab tsi yog P0746 cov kauj ruam daws teeb meem?

Ua ntej pib txheej txheem daws teeb meem rau ib qho teeb meem, koj yuav tsum tshuaj xyuas lub tsheb tshwj xeeb Cov Kev Pabcuam Cov Lus Tshaj Tawm (TSB) los ntawm xyoo, qauv thiab kev xa tawm. Hauv qee kis, qhov no tuaj yeem txuag koj ntau lub sijhawm hauv qhov ntev los ntawm kev taw qhia koj mus rau qhov yog. Koj kuj yuav tsum txheeb xyuas cov ntaub ntawv tsheb kom kuaj xyuas thaum lub lim dej thiab cov kua tau hloov pauv zaum kawg, yog tias ua tau.

Txheeb xyuas cov dej thiab cov xov hlau

Thawj kauj ruam yog tshuaj xyuas qib kua thiab xyuas seb cov kua puas muaj kab mob sib kis. Ua ntej hloov cov kua, koj yuav tsum txheeb xyuas cov ntaub ntawv tsheb kom paub seb lub lim dej thiab cov kua tau hloov pauv zaum kawg.

Qhov no yog ua raws los ntawm kev tshuaj xyuas kom ntxaws txhawm rau txheeb xyuas qhov xwm txheej ntawm cov kab thaiv kom pom qhov tsis xws. Txheeb xyuas cov khoom sib txuas thiab kev sib txuas kom nyab xeeb, xeb thiab puas rau pins. Qhov no yuav tsum suav nrog txhua txoj kab hluav taws xob thiab cov txuas sib txuas rau kev xa xov siab tswj solenoids, kis twj tso kua mis, thiab PCM. Lub tshuab xa hluav taws xob tuaj yeem siv hluav taws xob lossis tshuab ua haujlwm, nyob ntawm qhov teeb tsa.

Cov qib siab

Cov kauj ruam ntxiv ib txwm yog lub tsheb tshwj xeeb thiab xav tau cov cuab yeej tsim nyog los ua kom raug. Cov txheej txheem no xav tau digital multimeter thiab cov ntaub ntawv qhia txog kev siv tsheb tshwj xeeb. Koj yuav tsum tau txais cov lus qhia tshwj xeeb txog kev daws teeb meem rau koj lub tsheb ua ntej mus txuas ntxiv nrog cov kauj ruam dhau los. Qhov xav tau hluav taws xob tuaj yeem sib txawv heev los ntawm cov qauv tsheb rau tsheb. Cov kua dej xav tau kuj yuav txawv raws qhov tsim qauv thiab teeb tsa.

Kev tshuaj xyuas txuas ntxiv

Tshwj tsis yog qhov tshwj xeeb tau teev tseg hauv cov ntawv teev tseg, cov xov hlau txuas ib txwm thiab txuas txuas yuav tsum yog 0 ohms ntawm kev tiv thaiv. Kev tshuaj xyuas txuas ntxiv yuav tsum tau ua tas li nrog lub zog txuas hluav taws xob raug txiav tawm kom tsis txhob luv luv ntawm lub Circuit Court thiab ua rau muaj kev puas tsuaj ntau dua. Kev tiv thaiv lossis tsis muaj kev txuas mus txuas ntxiv qhia tias cov xov tooj tsis raug uas tau qhib lossis luv thiab xav tau kev kho lossis hloov pauv.

Cov txheej txheem txheej txheem kho qhov chaws no yog dab tsi?

• Hloov dej thiab lim dej
• Hloov qhov tsis xws luag tswj solenoid.
• Kho lossis hloov lub twj tso kua mis tsis raug
• Kho lossis hloov qhov ua tsis raug lub cev lub cev
• Kev yaug cov dej kom huv huv
• Ntxuav cov khoom sib txuas los ntawm kev xeb
• Kho lossis hloov cov thaiv
• Flashing lossis hloov PCM

Tej zaum yuav kuaj tsis tau muaj xws li:

• Qhov teeb meem cav tsis zoo
• Qhov teeb meem kis tau tus mob
• Teeb meem kev sib kis sab hauv
• Teeb meem kis tau tus mob

Vam tias cov ntaub ntawv hauv kab lus no tau pab taw koj hauv txoj hauv kev rau kev daws koj qhov kev tswj siab solenoid DTC teeb meem. Kab lus no yog rau cov ntaub ntawv xov xwm nkaus xwb thiab cov ntaub ntawv qhia tshwj xeeb thiab cov ntawv xov xwm pabcuam rau koj lub tsheb yuav tsum yog qhov tseem ceeb tshaj plaws.

Tus kws kho tsheb kuaj xyuas tus lej P0746 li cas?

Koj tus kws kho tsheb yuav xub siv OBD-II scanner kom paub seb cov lej twg tau khaws cia. Tom qab ntawd lawv yuav kuaj xyuas lub siab hauv kev sib kis. Tom qab ntawd, lawv yuav tshuaj xyuas cov kua dej sib kis kom pom tias muaj kev sib kis (los yog xav tau ntau dua). Yog tias cov kua tsw tsw qab, lub lauj kaub xaim yuav tsum tau kuaj xyuas.

Koj tus kws kho tsheb tseem yuav xav saib tag nrho cov xov hlau uas pab tswj lub siab tswj solenoid. Lwm yam khoom siv hluav taws xob xws li cov khoom sib txuas kuj tseem ceeb rau kev kuaj xyuas. Lub twj tso kua mis siab kuj yuav tsum tau kuaj.

Feem ntau yuam kev thaum kuaj tus lej P0746

Thaum nws tseem ceeb heev rau kev kuaj xyuas, lub twj tso kua mis siab yog feem ntau raug liam rau tag nrho cov cai thiab yog li hloov pauv sai yam tsis muaj kev saib xyuas zoo rau cov txheej txheem. Hloov chaw, kev xaim tsis raug thiab tsis raug hluav taws xob hluav taws xob tswj cov solenoids feem ntau yuav yog lub luag haujlwm rau tus lej P0746. Qhov no yuav tsum tau ua ib qho kev ceeb toom kom kuaj xyuas kom meej ua ntej pib nrog kev ntsuas tsis tuaj yeem.

P0746 code loj npaum li cas?

Cov cai tsis tas txhais tau tias muaj qee yam txaus ntshai lossis teeb meem uas yuav ua rau koj lub tsheb puas yog tias nws tsis kho tam sim ntawd. Txawm li cas los xij, raws li koj tau pom los ntawm cov tsos mob saum toj no, nws yog qhov ua tau tag nrho tias koj qhov kev sib kis yuav xaus mus rau overheating lossis lub clutch tsis koom nrog. Qhov no tuaj yeem raug nqi thiab tsawg kawg tuaj yeem ua rau muaj teeb meem loj dua hauv txoj kev, yog li nws yog ib lub tswv yim zoo los daws cov cai no kom sai li sai tau.

Kev kho dab tsi tuaj yeem kho tus lej P0746?

Kev kho tsheb yuav xav tau cov hauv qab no:

• Hloov / kho faulty twj tso kua mis
• Kho cov kua dej sib kis
