P0748 Kev tswj siab solenoid valve A hluav taws xob

OBD-II Teeb meem Code - P0748 ​​​​- Kev piav qhia

P0748 - Siab tswj solenoid valve A, hluav taws xob.

Cov cai no sawv cev rau Hluav Taws Xob Tswj Solenoid. Cov cai no yuav muaj cov ntsiab lus sib txawv rau qee lub npe tsheb, yog li nco ntsoov xyuas cov lej tshwj xeeb rau koj lub tsheb.

Qhov teeb meem code P0748 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 P0748 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.

P0748 tau teeb tsa los ntawm PCM thaum qhov "A" tswj lub siab solenoid ntsib teeb meem hluav taws xob.

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 P0748?

Yog tias qhov chaws no khaws cia, koj yuav tsis pom cov tsos mob pom tseeb, lossis koj tuaj yeem pom muaj teeb meem hloov pauv loj, xws li tsis muaj kev hloov pauv txhua. Lub cav yuav nres ntawm qhov tsis ua haujlwm, lub iav hloov pauv yuav hnyav lossis plam, thiab kev sib kis yuav dhau los. Lwm cov tsos mob suav nrog txo qis roj kev lag luam thiab lub teeb pom kev tsis zoo (MIL) rau. Lwm cov lej yuav raug teeb tsa, xws li cov uas muaj feem xyuam rau iav piv, hloov solenoids, lossis xaim xaim.

Cov tsos mob ntawm P0748 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

Dab tsi yog qee qhov ua rau pom cov cai?

Lub siab tswj solenoid valve tuaj yeem ua tsis tiav yog tias muaj qee yam hauv qab no:

• Cov kua paug kis kab mob los yog qias neeg
• Ua kua nrog tsawg throughput
• Hydraulic blockages nyob rau hauv cov ntaub ntawv kis tau tus mob
• Tsis zoo hluav taws xob tswj valve
• Mechanical internal transmission yuam kev
• Tsis Zoo TCM (Kev Sib Txuas Tswj Module)
• PCM puas (tsis tshua muaj)
• 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

Dab tsi yog P0748 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.

COMMON yuam kev thaum kuaj xyuas tus lej P0748

Feem ntau qhov kev ua haujlwm tsis zoo no tau tshaj tawm tias muaj teeb meem tsis zoo hauv lub cav lossis lub twj tso kua mis siab yog suav tias yog tus neeg ua txhaum. Kev xaim hluav taws xob thiab lwm cov khoom siv hluav taws xob tuaj yeem raug saib xyuas raws li qhov ua tau. Nws yog ib qho tseem ceeb kom paub meej tias cov txheej txheem kuaj mob tiav tiav.

YUAV TSUM TAU TXAIS P0748 YOG?

Cov teeb meem sib kis yuav tsum tau kho kom sai li sai tau. Txawm hais tias qhov teeb meem tsis tau nce mus rau qhov chaw uas muaj qhov tsis ua haujlwm hauv lub tshuab ua haujlwm tau tshwm sim, qhov pib ntawm cov tsos mob txhais tau tias muaj teeb meem uas tuaj yeem ua rau loj heev hauv lub sijhawm luv luv.

Kev kho dab tsi tuaj yeem kho tus lej P0748?

Kev kho tau rau qhov yuam kev no suav nrog:

• Kev kho cov kev tswj xyuas lub zog xws li cov xaim thiab cov khoom sib txuas
