P0641 Buɗe da'irar firikwensin Ƙarfin tunani

OBD-II Lambar Matsala - P0641 - Takardar Bayanai

P0641 - Sensor A Reference Voltage Circuit Buɗe

Menene ma'anar lambar matsala P0641?

Wannan Lambar Matsalar Bincike (DTC) lambar watsawa ce gaba ɗaya, wanda ke nufin ya shafi motocin OBD-II sanye take. Kodayake gabaɗaya a cikin yanayi, takamaiman matakan gyara na iya bambanta dangane da alama / ƙirar.

Lokacin da na sami lambar P0641 da aka adana, yana nufin tsarin sarrafa wutar lantarki (PCM) ya gano da'irar buɗewa don takamaiman firikwensin; An nuna a wannan yanayin a matsayin "A". Lokacin bincika lambar OBD-II, ana iya maye gurbin kalmar "buɗe" tare da "ɓacewa".

Na'urar firikwensin da ake tambaya galibi ana haɗa shi da watsawa ta atomatik, yanayin canja wuri, ko ɗaya daga cikin bambance-bambance. Wannan lambar kusan koyaushe ana biye da ita da ƙarin takamaiman lambar firikwensin. P0641 yana ƙara da cewa kewayawa a buɗe take. Tuntuɓi amintaccen tushen bayanan abin hawa (Dukkan Bayanan DIY babban zaɓi ne) don tantance wurin (da aikin) na firikwensin da ke da alaƙa da abin hawa da ake tambaya. Idan P0641 an adana shi daban, yi zargin an sami kuskuren shirye-shiryen PCM. Babu shakka kuna buƙatar tantancewa da gyara duk wasu lambobin firikwensin kafin bincike da gyara P0641, amma ku kula da da'ira na "A".

Ana amfani da siginar ƙarfin lantarki (yawanci volts biyar) akan firikwensin da ake tambaya ta hanyar canzawa (mai ƙarfi). Hakanan yakamata a sami siginar ƙasa. Na'urar haska tana iya samun juriya mai canzawa ko nau'in electromagnetic kuma yana rufe takamaiman da'ira. Juriya na firikwensin yana raguwa tare da ƙara matsin lamba, zazzabi ko sauri kuma akasin haka. Tun da juriya na firikwensin ya canza tare da yanayi, yana ba da PCM tare da siginar ƙarfin lantarki. Idan PCM ba ta karɓi wannan siginar shigar da wutar lantarki ba, ana ɗaukar da'ira a buɗe kuma za a adana P0641.

Hakanan ana iya haska Fitilar Alamar Rashin Aiki (MIL), amma ku sani cewa wasu motocin zasu ɗauki hawan tuki da yawa (tare da matsala) don MIL ya kunna. A saboda wannan dalili, dole ne ku ba PCM damar shigar da yanayin jiran aiki kafin ɗauka cewa kowane gyara ya yi nasara. Kawai cire lambar bayan gyara da tuki kamar yadda aka saba. Idan PCM ya shiga cikin yanayin shiri, gyara ya yi nasara. Idan an share lambar, PCM ba zai shiga cikin yanayin shirye ba kuma za ku san cewa har yanzu matsalar tana nan.

Tsanani da alamu

Tsananin P0641 da aka adana ya dogara ne akan da'irar firikwensin ke cikin yanayin buɗewa. Kafin ku iya tantance tsananin, kuna buƙatar sake duba sauran lambobin da aka adana.

Alamomin lambar P0641 na iya haɗawa da:

• Rashin iya canza watsawa tsakanin wasanni da yanayin tattalin arziki
• Gear canzawa malfunctions
• Jinkiri (ko rashin) na kunna watsawa
• Rashin watsawa don canzawa tsakanin XNUMXWD da XNUMXWD
• Rashin jakar canja wuri don sauyawa daga ƙananan zuwa babban kaya
• Rashin hadawa da bambancin gaban
• Rashin sa hannun cibiya ta gaba
• Ba daidai ba ne ko kuma baya aiki da ma'aunin sauri / odometer

Abubuwan da suka dace don P0641 code

Mai yiwuwa sanadin wannan lambar injin ya haɗa da:

• Buɗe kewaye da / ko masu haɗawa
• Fuses mara kyau ko busawa da / ko fuse
• Kuskuren tsarin wutar lantarki
• Mummunan firikwensin
• Ƙarfin sarrafa injin injin (ECM)
• Harafin ECM buɗe ko gajere
• ECM mara kyau na lantarki
• An gajarta firikwensin zuwa 5 volts Menene wannan ke nufi?

Hanyoyin bincike da gyara

Don tantance lambar P0641 da aka adana, Ina buƙatar samun dama ga na'urar binciken na’ura, volt / ohmmeter na dijital (DVOM), da amintaccen tushen bayanin abin hawa (kamar Duk Bayanai na DIY). Hakanan oscilloscope na hannu yana iya zama da amfani a ƙarƙashin wasu yanayi.

Yi amfani da tushen bayanan abin hawan ku don tantance wuri da aikin firikwensin da ake tambaya dangane da takamaiman abin hawa. Duba fuses na tsarin da cikakken kayan juyi. Fuses waɗanda za su iya bayyana kamar na al'ada lokacin da aka ɗora da'irar sosai, galibi suna kasawa lokacin da aka ɗora cikakken da'ira. Ya kamata a maye gurbin fuses masu busawa, a tuna cewa ɗan gajeren zango na iya zama sanadin fuse mai busa.

A gani duba tsarin firikwensin tsarin kayan haɗi da masu haɗawa. Gyarawa ko maye gurbin wayoyin da suka lalace ko ƙonewa, masu haɗawa, da abubuwan da ake buƙata kamar yadda ya cancanta.

Sannan na haɗa na'urar daukar hotan takardu zuwa soket ɗin mota kuma na sami duk DTCs da aka adana. Ina so in rubuta su tare da duk wani bayanan daskarewa mai alaƙa, saboda wannan bayanin na iya zama da taimako idan lambar ta zama mara daɗi. Bayan haka, zan ci gaba da share lambar kuma gwada gwajin motar don ganin ko ta sake farawa nan take.

Idan duk fuskokin tsarin suna da kyau kuma lambar zata sake farawa nan take, yi amfani da DVOM don gwada ƙarfin ƙarfin tunani da siginar ƙasa akan firikwensin da ake tambaya. Gabaɗaya, yakamata kuyi tsammanin samun volts biyar da ƙasa ɗaya a mai haɗa firikwensin.

Idan siginar wuta da siginar ƙasa suna nan a mai haɗa firikwensin, ci gaba da gwada juriya da matakan mutunci. Yi amfani da tushen bayanan abin hawa don samun takamaiman gwaji kuma kwatanta ainihin sakamakon ku da su. Sensors waɗanda basu cika waɗannan ƙayyadaddun bayanai ba ya kamata a maye gurbinsu.

Cire duk masu sarrafawa masu alaƙa daga tsarin kafin gwada juriya tare da DVOM. Idan babu siginar siginar ƙarfin lantarki a firikwensin, cire haɗin duk masu kula da haɗin gwiwa kuma yi amfani da DVOM don gwada juriya da ci gaba tsakanin firikwensin da PCM. Sauya da'irori masu buɗewa ko gajarta kamar yadda ya cancanta. Idan kuna amfani da firikwensin lantarki mai maimaitawa, yi amfani da oscilloscope don bin diddigin bayanan a ainihin lokacin; mai da hankali musamman ga glitches da cikakken buɗe da'ira.

Ƙarin bayanin kula:

• Ana bayar da irin wannan lambar azaman tallafi don ƙarin takamaiman lambar.
• Lambar ajiya P0641 galibi tana hade da watsawa.
