OBD-II Lambar Matsala - P0651 - Takardar Bayanai

P0651 - Buɗe da'irar ƙarfin lantarki na firikwensin "B"

Menene ma'anar lambar matsala P0651?

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 da aka adana P0651, yana nufin tsarin sarrafa wutar lantarki (PCM) ya gano da'irar buɗewa don takamaiman firikwensin; An nuna a wannan yanayin a matsayin "B". 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. P0651 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 P0651 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 P0651, amma ku kula da da'irar "B" da ke buɗe.

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 P0651.

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 P0651 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 P0651 na iya bambanta, don haka yana da mahimmanci a fahimci batutuwa daban-daban da kuke iya fuskanta. Wannan yana iya haɗawa da wahala ko rashin farawa, injin na iya fara aiki mai ƙarfi, ko kuma kuna iya lura cewa abin hawa ba ya da ƙarfin man fetur kamar yadda yake a da. Injin na iya yin kuskure kuma wataƙila za ku lura da ƙarancin wuta a cikin motar. Idan an adana DTC kuma hasken Injin Duba yana kashe, lambar na iya nunawa tana jiran. Koyaya, a wasu lokuta, hasken injin yana iya kasancewa.

Alamomin lambar P0651 na iya haɗawa da:

• Rashin iya canza watsawa tsakanin wasanni da yanayin tattalin arziki

Hanyoyin bincike da gyara

Don tantance lambar P0651 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.
