P0641 Qhib Circuit Court ntawm sensor Ib qho siv hluav taws xob

OBD-II Teeb meem Code - P0641 ​​​​- Kev piav qhia

P0641 - Sensor A Reference Voltage Circuit Qhib

Qhov teeb meem code P0641 txhais li cas?

Qhov Diagnostic Trouble Code (DTC) no yog tus lej siv dav, uas txhais tau tias nws siv rau OBD-II cov tsheb uas muaj cuab yeej siv. Txawm hais tias qhov dav dav, cov txheej txheem kho tshwj xeeb yuav txawv nyob ntawm cov khoom lag luam / qauv.

Thaum kuv pom tus lej khaws cia P0641, nws txhais tau tias lub zog tswj hluav taws xob tswj (PCM) tau kuaj pom qhov qhib hluav taws xob rau lub ntsuas tshwj xeeb; denoted nyob rau hauv cov ntaub ntawv no "A". Thaum kuaj pom tus lej OBD-II, lo lus "qhib" tuaj yeem hloov nrog "ploj".

Lub sensor nyob rau hauv nqe lus nug feem ntau yog txuam nrog ib tug tsis siv neeg kis tau tus mob, hloov rooj plaub, los yog ib tug ntawm qhov sib txawv. Cov cai no yuav luag ib txwm ua raws li qhov tshwj xeeb sensor code. P0641 ntxiv tias lub voj voog qhib. Nrog rau kev ntseeg siab ntawm lub tsheb cov ntaub ntawv (Tag nrho cov ntaub ntawv DIY yog ib qho kev xaiv zoo) los txiav txim qhov chaw (thiab kev ua haujlwm) ntawm lub sensor ntsig txog lub tsheb hauv nqe lus nug. Yog tias P0641 khaws cia nyias, xav tias PCM programming yuam kev tau tshwm sim. Pom tseeb koj yuav tsum kuaj xyuas thiab kho lwm yam kev ntsuas ntsuas ua ntej kuaj thiab kho P0641, tab sis yuav tsum paub txog "A" qhib Circuit Court.

Ib qho kev siv hluav taws xob (feem ntau yog tsib volts) tau siv rau lub sensor hauv cov lus nug los ntawm kev hloov pauv (tseem ceeb-siv) Circuit Court. Yuav tsum muaj lub teeb liab hauv av. Lub sensor zoo li yuav muaj qhov hloov pauv tsis tau lossis ntau yam khoom siv hluav taws xob thiab kaw qhov tshwj xeeb hauv Circuit Court. Qhov tsis kam ntawm lub ntsuas hluav taws xob poob qis nrog kev nce siab, kub lossis nrawm thiab hloov pauv. Txij li qhov tsis kam ntawm lub ntsuas hloov pauv nrog cov xwm txheej, nws muab PCM nrog cov teeb liab nkag mus. Yog tias qhov ntsuas hluav taws xob nkag hluav taws xob tsis tau txais los ntawm PCM, lub Circuit Court tau txiav txim siab qhib thiab P0641 yuav muab khaws cia.

Lub Teeb Pom Teeb Pom Kev Tsis Zoo (MIL) kuj tseem tuaj yeem pom teeb ci, tab sis nco ntsoov tias qee lub tsheb yuav siv ntau txoj kev tsav tsheb (nrog kev ua haujlwm tsis zoo) rau MIL kom qhib. Vim li no, koj yuav tsum tso cai rau PCM nkag mus rau hom tos ua ntej xav tias kev kho tau zoo. Tsuas yog tshem cov cai tom qab kho thiab tsav zoo li qub. Yog tias PCM nkag mus rau hauv hom kev npaj, kev kho tau ua tiav. Yog tias txoj cai raug tshem tawm, PCM yuav tsis mus rau hauv hom npaj thiab koj yuav paub tias qhov teeb meem tseem muaj.

Mob hnyav thiab tsos mob

Qhov hnyav ntawm kev khaws cia P0641 nyob ntawm seb qhov ntsuas hluav taws xob nyob hauv lub xeev qhib. Ua ntej koj tuaj yeem txiav txim siab qhov hnyav, koj yuav tsum tshuaj xyuas lwm cov lej khaws cia.

Cov tsos mob ntawm tus lej P0641 tuaj yeem suav nrog:

• Tsis muaj peev xwm hloov pauv kev sib kis ntawm kev ua kis las thiab kev lag luam
• Gear hloov ua haujlwm tsis zoo
• Kev ncua (lossis tsis muaj) ntawm tig rau kis
• Kev xa mus tsis hloov pauv ntawm XNUMXWD thiab XNUMXWD
• Ua tsis tiav ntawm cov ntaub ntawv hloov pauv los ntawm qis mus rau lub iav siab
• Tsis muaj kev suav nrog ntawm qhov sib txawv hauv ntej
• Tsis muaj kev koom tes ntawm lub hauv ntej hub
• Tsis raug lossis tsis ua haujlwm speedometer / odometer

Ua rau P0641 code

Qhov ua tau ntawm lub cav no suav nrog:

• Qhib Circuit Court thiab / lossis txuas
• Tsis zoo lossis tshuab fuses thiab / lossis fuses
• Faulty system fais fab tuag relay
• Tsis zoo sensor
• Lub cev muaj zog tswj module (ECM)
• ECM hlua qhib los yog luv
• Cov hluav taws xob tsis zoo ECM
• Lub sensor luv luv rau 5 volts Qhov no txhais li cas?

Kev kuaj mob thiab kho cov txheej txheem

Txhawm rau txheeb xyuas qhov khaws cia P0641, kuv yuav xav tau nkag mus rau lub tshuab ntsuas kab mob, lub ntsuas hluav taws xob volt / ohm meter (DVOM), thiab ntseeg tau qhov chaw ntawm cov ntaub ntawv tsheb (xws li Txhua Cov Ntaub Ntawv DIY). Lub tes oscilloscope tseem tuaj yeem pab tau nyob rau qee qhov xwm txheej.

Siv koj lub tsheb cov ntaub ntawv xov xwm los txiav txim qhov chaw thiab kev ua haujlwm ntawm lub ntsuas pa hauv nqe lus nug vim nws cuam tshuam nrog koj lub tsheb tshwj xeeb. Txheeb xyuas qhov system fuses thiab thauj khoom tag nrho. Cov fuses uas tuaj yeem tshwm sim ib txwm thaum lub Circuit Court tau thauj khoom hnyav heev, feem ntau ua tsis tiav thaum cov khoom siv tau puv. Cov tshuab fuse yuav tsum tau hloov, nco ntsoov tias luv Circuit Court yog qhov ua rau lub fuse cua tshuab.

Pom qhov muag pom cov kab ke ua haujlwm thaiv cov hlua thiab cov txuas. Kho lossis hloov cov hlua puas lossis raug hlawv, cov txuas, thiab cov khoom siv raws li qhov tsim nyog.

Tom qab ntawd kuv txuas lub tshuab luam ntawv mus rau lub tsheb ntsuas kab mob thiab tau txais txhua qhov khaws cia DTCs. Kuv nyiam sau lawv nrog rau txhua qhov cuam tshuam khov cov ntaub ntawv, raws li cov ntaub ntawv no tuaj yeem pab tau yog tias cov cai dhau los ua qhov ntxeev. Tom qab ntawd, Kuv yuav mus tom ntej thiab tshem cov cai thiab sim tsav lub tsheb kom pom tias nws rov pib dua tam sim.

Yog tias txhua qhov system fuses tsis ua li cas thiab cov cai rov pib dua tam sim ntawd, siv DVOM los ntsuas qhov ntsuas hluav taws xob thiab cov lus qhia hauv av ntawm lub sensor hauv lo lus nug. Feem ntau, koj yuav tsum cia siab tias yuav muaj tsib qhov hluav taws xob thiab ib qho hauv av ntawm qhov ntsuas qhov ntsuas.

Yog tias qhov hluav taws xob thiab cov cim hauv av tau tshwm sim ntawm lub ntsuas qhov ntsuas, txuas ntxiv mus ntsuas lub ntsuas qhov tsis kam thiab qib kev ncaj ncees. Siv koj cov ntaub ntawv xov xwm tsheb kom tau txais kev xeem tshwj xeeb thiab sib piv koj cov txiaj ntsig tiag nrog lawv. Cov ntsuas cua uas tsis ua tau raws cov kev qhia tshwj xeeb no yuav tsum raug hloov pauv.

Txiav tawm txhua qhov kev tswj hwm cuam tshuam los ntawm cov kab ke ua ntej ntsuas kev tiv thaiv nrog DVOM. Yog tias tsis muaj qhov ntsuas hluav taws xob siv hluav taws xob ntawm lub ntsuas hluav taws xob, tshem tawm txhua qhov kev tswj hwm cuam tshuam thiab siv DVOM los ntsuas qhov kev tiv thaiv hluav taws xob thiab txuas ntxiv ntawm lub sensor thiab PCM. Hloov qhov qhib lossis luv Circuit Court raws li qhov tsim nyog. Yog tias siv lub ntsuas hluav taws xob sib nqus sib nqus, siv lub oscilloscope los taug qab cov ntaub ntawv hauv lub sijhawm tiag; them nyiaj tshwj xeeb rau cov teeb meem thiab qhib lub voj voog.

Cov ntawv kuaj mob ntxiv:

• Hom kev cai no feem ntau yog muab los txhawb rau cov cai tshwj xeeb.
• Tus lej khaws cia P0641 feem ntau yog cuam tshuam nrog kev sib kis.
