Wurin Fitar da Saurin Fitar da Wutar Lantarki - Asarar siginar kai

Mene ne wannan yake nufi?

Wannan Lambar Matsalar Ciwon Cutar Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararru (DTC) galibi ana amfani da ita ga motocin OBD-II da yawa. Wannan na iya haɗawa amma ba'a iyakance ga Chevrolet, Ford, Toyota, Dodge, Honda, da sauransu.

Lokacin da abin hawan ku ya adana lambar P077A, yana nufin tsarin sarrafa wutar lantarki (PCM) ya gano asarar siginar jagora daga firikwensin saurin fitarwa.

Na'urorin firikwensin saurin fitarwa yawanci electromagnetic ne. Suna amfani da wasu nau'in zobe na amsa haƙora ko kayan aiki wanda ke haɗe da madaidaicin tashar watsawa. Yayin da shaft ɗin fitarwa ke juyawa, zoben reactor yana juyawa. Hakoran hakora na zobe mai kunnawa suna rufe da'irar firikwensin saurin fitarwa yayin da suke wucewa kusa da firikwensin wutar lantarki. Lokacin da reactor ya wuce ƙarar electromagnetic na firikwensin, ƙira tsakanin hakora na zobe na reactor yana haifar da katsewa a cikin da'irar firikwensin. Wannan haɗin ƙarshen ƙarewa da katsewa PCM (da sauran masu sarrafawa) suna karɓar su azaman samfuran raƙuman ruwa waɗanda ke wakiltar ƙimar baud fitarwa.

Ana haska firikwensin kai tsaye a cikin gidan watsawa ko kuma a riƙe shi a wurin tare da ƙulle. Ana amfani da O-ring don hana ruwa ya zubo daga ramin firikwensin.

PCM yana kwatancen saurin shigarwa da fitarwa na watsawa don tantance idan watsawar ta canza daidai kuma tana aiki yadda yakamata.

Idan an adana P077A, PCM ya gano siginar shigar da wutar lantarki daga firikwensin saurin fitarwa wanda ke nuni da cewa zoben reactor baya motsi. Lokacin da siginar firikwensin saurin fitarwa ba ya canzawa, PCM yana ɗauka cewa zoben reactor ya daina motsi ba zato ba tsammani. PCM tana karɓar abubuwan shigar da saurin abin hawa da abubuwan shigar da sauri ban da bayanan firikwensin saurin fitarwa. Ta hanyar kwatanta waɗannan sigina, PCM na iya tantance ko zoben reactor yana motsawa sosai (bisa ga sigina daga firikwensin saurin fitarwa). Ana iya haifar da siginar firikwensin saurin fitarwa ta ko dai matsalar lantarki ko matsalar inji.

Ga misalin firikwensin saurin watsawa:

Menene tsananin wannan DTC?

Sharuɗɗan da ke ba da gudummawa ga dorewar lambar P077A na iya ko na iya haifar da gazawar watsa bala'i kuma ya kamata a gyara cikin gaggawa.

Menene wasu alamomin lambar?

Alamomin lambar injin P077A na iya haɗawa da:

Ana iya adana wasu lambobin watsawa da / ko ABS

Mene ne wasu abubuwan da ke haifar da lambar?

Dalilan wannan lambar na iya haɗawa da:

Gazawar watsawa ta inji

Menene wasu matakan matsala na P077A?

Yawancin lokaci ina so in fara bincikar P077A tare da dubawa na gani na tsarin wayoyi da masu haɗawa. Zan cire firikwensin saurin fitarwa kuma in cire tarkacen ƙarfe da ya wuce kima daga tip ɗin maganadisu. Yi hankali lokacin cire firikwensin kamar yadda zafi mai zafi zai iya fita daga cikin ma'aunin firikwensin. Gyara bude ko gajeriyar da'ira a cikin da'irori da masu haɗawa idan ya cancanta.

Bayan cire firikwensin don dubawa, duba zoben reactor. Idan zoben reactor ya lalace, ya fashe, ko kuma idan wasu hakora sun ɓace (ko sun tsufa), da alama kun sami matsalar ku.

Duba ruwan watsawa ta atomatik idan wasu alamun alaƙa da watsawa sun bayyana. Ruwan ya kamata ya bayyana mai tsabta kuma baya jin ƙanshin ƙonawa. Idan matakin ruwan watsawa yana ƙasa da kwata ɗaya, cika da ruwa mai dacewa kuma duba don kwarara. Dole ne a cika watsawa da madaidaicin ruwa kuma a cikin yanayin injiniya mai kyau kafin bincike.

Zan buƙaci na'urar daukar hoto tare da ginanniyar oscilloscope, dijital volt/ohmmeter (DVOM) da ingantaccen tushen bayanan abin hawa don tantance lambar P077A.

Ina so in haɗa na'urar daukar hotan takardu zuwa tashar binciken abin hawa sannan in dawo da duk DTC da aka adana da daskare bayanan firam. Zan rubuta wannan bayanin kafin share kowane lamba, saboda yana iya zama da amfani yayin da bincike na ke ci gaba.

Nemo Takaddun Sabis na Fasaha masu dacewa (TSB) ta amfani da tushen bayanan abin hawan ku. Nemo TSB wanda ya dace da alamun cutar da lambobin da aka adana (don abin hawa da ake tambaya) wataƙila zai haifar da ganewar asali da sauri.

Yi amfani da rafin bayanan na'urar daukar hotan takardu don saka idanu kan saurin fitarwa yayin gwajin abin hawa. Karkatar da rafin bayanai don nuna filayen da suka dace kawai zai haɓaka saurin da daidaiton isar da bayanai. Alamu marasa daidaituwa ko rashin daidaituwa daga shigarwar ko firikwensin saurin fitarwa na iya haifar da matsaloli tare da wayoyi, mai haɗa wutar lantarki, ko firikwensin.

Cire haɗin firikwensin saurin fitarwa kuma amfani da DVOM don gwada juriya. Tushen bayanan abin hawan ku yakamata ya haɗa da zane -zanen wayoyi, nau'ikan haɗin haɗin, makullin mai haɗawa, da hanyoyin gwaji / ƙayyadaddun ƙira. Idan firikwensin saurin fitarwa ya fita daga cikin ƙayyadaddun bayanai, yakamata a ɗauka mara lahani.

Ana iya samun bayanai na ainihi daga firikwensin saurin fitarwa ta amfani da oscilloscope. Duba siginar saurin siginar siginar siginar waya da waya ta firikwensin. Kuna iya buƙatar ja ko ɗaga abin hawa don kammala irin wannan gwajin.
