P0741 Torque Converter Clutch Circuit Performance lossis Nres Tawm

OBD-II Teeb meem Code - P0741 ​​​​- Kev piav qhia

P0741 - Torque converter clutch Circuit Court kev ua tau zoo los yog daig tawm.

Qhov Kev Ntsuas Teeb Meem Diagnostic (DTC) no yog hom kab ke OBD-II kis tau tus mob. Nws tau txiav txim siab thoob ntiaj teb raws li nws siv rau txhua qhov ua thiab qauv ntawm lub tsheb (1996 thiab tshiab dua), txawm hais tias cov kev kho tshwj xeeb yuav txawv nyob ntawm tus qauv.

Qhov teeb meem code P0741 txhais li cas?

Hauv cov tsheb niaj hnub nruab nrog lub tshuab tsis siv neeg / hloov pauv, lub zog hloov pauv tau siv nruab nrab ntawm lub cav thiab kev sib kis kom nce lub cav lub zog tso zis thiab tsav lub log tsheb tom qab.

Lub cav thiab kev sib kis tau txuas tau zoo los ntawm lub tshuab ua haujlwm hydraulic sab hauv lub zog hloov pauv, uas ua kom lub zog nce mus txog qhov nrawm sib npaug thiab tsim "nres" nrawm, qhov sib txawv ntawm lub cav rpm tiag tiag thiab xa tawm rpm yog li 90%. ... Torque Converter Clutch (TCC) solenoids, tswj los ntawm Powertrain Control Module / Engine Control Module (PCM / ECM) lossis Transmission Control Module (TCM), channel hydraulic fluid thiab koom nrog lub zog hloov pauv clutch kom muaj zog txuas thiab txhim kho kev ua haujlwm.

TCM tau kuaj pom qhov ua haujlwm tsis zoo hauv Circuit Court uas tswj lub zog hloov pauv clutch solenoid.

Nco tseg. Tus lej no zoo ib yam li P0740, P0742, P0743, P0744, P2769 thiab P2770.

Tej zaum yuav muaj lwm yam DTCs cuam tshuam nrog kev tswj hwm kev sib kis uas tuaj yeem nkag mus tau nrog cov cuab yeej ntsuas siab. Yog tias muaj lub zog txuas ntxiv DTC tshwm sim ntxiv rau P0741, yuav muaj peev xwm ua tsis tiav.

Cov tsos mob

Cov tsos mob ntawm P0741 teeb meem chaws yuav suav nrog:

• Ua haujlwm lossis hover tawm lub teeb ceeb toom (MIL) teeb pom kev zoo (tseem hu ua lub teeb ceeb toom cav)
• Qhov txo qis hauv kev siv roj tsawg, nws yuav tsis cuam tshuam rau kev ua haujlwm ntawm lub cav.
• Xyuas kom lub cav lub teeb yog nyob rau
• Kev siv roj ntau ntxiv
• Cov tsos mob zoo ib yam li qhov tsis raug
• Lub tsheb yuav nres tom qab tsav tsheb ntawm kev kub ceev
• Lub tsheb tsis tuaj yeem upshift ntawm kev kub ceev.
• Tsis tshua muaj, tab sis qee zaum tsis muaj tsos mob

Tej Yam Ua Tau ntawm Code P0741

Cov laj thawj rau DTC no suav nrog:

• Cov hlua hluav taws xob mus rau lub iav tau luv rau hauv av
• Sab hauv luv Circuit Court ntawm lub zog hloov pauv clutch (TCC) solenoid
• Kev tswj kev xa xov (TCM)
• Faulty TSS
• Faulty torque converter xauv-up solenoid
• Internal luv Circuit Court hauv TCC solenoid
• Txuas rau TCC solenoid puas
• Faulty valve lub cev

DTC P0741 Kev Ua Haujlwm Teeb Meem

Thaiv - Txheeb xyuas cov hlua khi rau kev puas tsuaj lossis kev sib txuas xoob. Siv lub Hoobkas xaim daim duab kos kom pom cov khoom siv hluav taws xob tsim nyog thiab tag nrho cov ntsiab lus txuas ntawm circuits. Cov kis tau tus mob tuaj yeem siv los ntawm fuse lossis relay thiab khiav los ntawm TCM. Disconnect tus kis tau tus mob harness los ntawm kis tau tus mob connector, fais fab mov thiab TCM.

Txheeb xyuas qhov luv luv rau hauv av hauv cov hlua sib kis los ntawm kev nrhiav qhov tsim nyog + thiab - tus pins ntawm lub torque converter clutch solenoid. Siv lub tshuab hluav taws xob digital (DVOM) teeb tsa rau ohm nplai, ntsuas qhov luv luv rau hauv av hauv Circuit Court nrog cov xaim zoo ntawm ob lub davhlau ya nyob twg thiab cov xaim tsis zoo rau hauv av paub zoo. Yog tias tsis muaj kev tiv thaiv tsawg, xav tias luv luv rau hauv av hauv cov hlua hluav taws xob sab hauv lossis TCC solenoid - tshem tawm cov roj xa hluav taws xob yuav tsum tau kuaj xyuas ntxiv rau TCC solenoid.

Txheeb xyuas qhov txuas ntawm TCM thiab cov hlua sib txuas ntawm cov ntaub ntawv hloov pauv siv DVOM teeb tsa rau ohms. Txheeb xyuas qhov ua txhaum hauv av los ntawm kev txav cov hmoov txhuas tsis zoo ntawm DVOM mus rau qhov paub zoo hauv av, qhov kev tiv thaiv yuav tsum siab heev lossis dhau qhov txwv (OL).

Torque Converter Clutch (TCC) Solenoid - Txheeb xyuas qhov kev tiv thaiv hauv TCC solenoid thiab cov xaim hluav taws xob sab hauv ntawm cov ntaub ntawv kis tau tus mob tom qab tshem tawm cov hlua txuas txuas (yog tias tsim nyog, qee qhov ua / qauv siv TCM bolted ncaj qha mus rau kis kab mob). Qee qhov ua / qauv siv cov hlua sib kis nrog TCC solenoid thiab cov hlua sab hauv ua ib chav. Nrog rau DVOM teeb rau ohms, kos rau luv luv rau hauv av nrog cov xaim zoo ntawm ib qho ntawm cov voj voog mus rau TCC thiab cov xaim tsis zoo rau hauv av paub zoo. Qhov kev tiv thaiv yuav tsum siab heev los yog dhau qhov txwv (OL), yog tias qis, qhov luv luv rau hauv av yog xav tias.

Txheeb xyuas qhov ntsuas hluav taws xob ntawm TCC cov khoom siv hluav taws xob lossis cov hlua txuas ntawm TCM nrog DVOM teeb tsa rau qhov ntsuas hluav taws xob, qhov zoo ntawm cov hlau nyob hauv kev sim thiab tsis zoo rau qhov paub zoo hauv av thaum nyob rau / cav tawm, roj teeb hluav taws xob yuav tsum muaj tam sim no. Yog tias tsis muaj qhov hluav taws xob tam sim no, txiav txim siab lub zog poob hauv Circuit Court siv cov khoom siv hluav taws xob daim duab qhia chaw rau siv.

Kev tswj kev xa xov (TCM) - Vim tias lub torque converter clutch tsuas yog qhib rau hauv qee qhov kev tsav tsheb, nws yuav tsim nyog los saib xyuas TCM nrog cov cuab yeej scan siab los txiav txim siab seb TCM tau hais kom TCC solenoid thiab qhov txiaj ntsig tawm tswv yim yog dab tsi ntawm TCM. TCC solenoid feem ntau yog lub luag haujlwm lub voj voog tswj kom ua kom yooj yim dua torque converter kev koom tes. Txhawm rau txheeb xyuas seb TCM puas tau xa cov teeb liab, koj tseem yuav xav tau lub luag haujlwm lub voj voog graphical multimeter lossis digital cia oscilloscope.

Cov xaim zoo yog kuaj hauv cov hlua txuas nrog TCM, thiab cov xaim tsis zoo raug sim rau hauv av paub zoo. Lub voj voog lub luag haujlwm yuav tsum yog tib yam li TCM tau teev tseg hauv qhov txuas ntxiv scan tool readout. Yog tias lub voj voog nyob ntawm 0% lossis 100% lossis tsis sib xws, rov kuaj xyuas cov kev sib txuas thiab yog tias tag nrho cov xaim / solenoid yog OK, TCM yuav ua yuam kev.

COMMON yuam kev thaum kuaj xyuas tus lej P0741

DTC P0741 tuaj yeem nyuaj rau kev kuaj mob. Nco ntsoov xyuas tag nrho cov xaim xaim, TCM thiab TCC solenoids.

Nco ntsoov tias tej zaum nws yuav tsim nyog los txo lub vaj huam sib luag tsav kom nkag mus rau tag nrho cov cables. Lub torque converter feem ntau yog hloov thaum qhov teeb meem tiag tiag yog faulty TCC solenoid lossis valve lub cev.

YUAV TSUM TAU TXAIS P0741 YOG?

Lub xub ntiag ntawm DTC P0741 qhia tias muaj kev sib kis tsis zoo. Tsav tsheb nyob rau hauv cov xwm txheej no yuav ua rau muaj kev puas tsuaj rau lwm yam sab hauv ntawm kev sib kis. Vim li no, DTC P0741 yog suav tias yog loj heev thiab yuav tsum tau kho kom sai li sai tau.

Kev kho dab tsi tuaj yeem kho tus lej P0741?
