Bayyanar Lalacewa: Yana iya sa injin ya kasa kunnawa, wutar lantarki ta ragu, yawan amfani da mai ya ƙaru ko kuma ya yi ƙwanƙwasa.
Nau'ikan samfura na yau da kullun: Misali, Audi Q5 na 2015 yana da sandunan camshaft guda biyu kuma yana buƙatar na'urori masu auna firikwensin guda biyu don sa ido daban-daban.
Idan na'urar firikwensin camshaft ta mota ta lalace, alamu kamar wahalar farawa, raguwar wutar lantarki, ƙaruwar amfani da mai, girgiza jiki, da kuma hasken gargaɗi da ke kunne yawanci yakan bayyana. Yana bayyana kamar haka:
Youdaoplaceholder0 Farawar da ba ta dace ba : Injin ya kasa kunna wuta ko kuma yana da wahalar kunnawa. Yana iya ɗaukar ƙoƙari da yawa kafin ya yi nasara. Wannan na iya faruwa a yanayin sanyi da zafi na injin.
Youdaoplaceholder0 Matsalar fitar da wutar lantarki : ƙarancin hanzari, jinkirin amsawar matsi, da kuma rashin ƙarfi a lokacin tuki, har ma da girgiza jiki.
Youdaoplaceholder0 Lalacewar tattalin arzikin mai : Yawan man fetur ya ƙaru sosai saboda rashin iyawar ECU na sarrafa adadin man da aka saka, wanda hakan ya haifar da ƙonewar mai ba tare da cikakke ba.
Youdaoplaceholder0 Aiki mara tabbas : Saurin injin ba shi da tabbas kuma girgizar tana bayyana a fili a lokacin aiki. Girgizar tana ƙaruwa a ƙarƙashin nauyi mai yawa. Wasu motoci na iya fuskantar girgizar tuƙi ko tsayawa kwatsam lokacin da suke dumama.
Matsalar Kuskuren Youdaoplaceholder0 : Hasken lalacewar injin da ke kan dashboard (kamar lambobin kuskuren OBD P0340-P0344) yana ci gaba da kunnawa, yana nuna cewa tsarin ya gano sigina mara kyau.
Idan alamun da ke sama suka bayyana, ana ba da shawarar a duba injin kuma a gyara shi cikin lokaci domin hana sake lalacewa daga injin.
Bayan matsalar na'urar firikwensin matsayi na camshaft, abin hawa ba zai iya aiki yadda ya kamata ba. Tilasta tuƙi na iya haifar da mummunar lalacewa ga injin da kuma haɗarin tsaro kamar tsayawa yayin tuƙi. Ana buƙatar gyara nan take.

Na'urar firikwensin matsayi na camshaft wani muhimmin sashi ne na tsarin sarrafa injin, wanda ke da alhakin samar da siginar matakin camshaft ga ECU (Na'urar Kula da Lantarki) don sarrafa jerin kunna wuta daidai, lokacin allurar mai, da kuma rage fashewar. Da zarar ya lalace, ECU ba zai iya gane matsayin silinda daidai ba, wanda ke haifar da gazawar sarrafa injin da kuma motar ba za ta iya kula da aiki yadda ya kamata ba. Musamman an bayyana shi kamar haka:
Youdaoplaceholder0 Yana da wahalar farawa ko kuma ba zai iya farawa ba : Bayan gazawar firikwensin, ECU yana buƙatar dogara da siginar matsayin crankshaft don gano matsayin camshaft a kaikaice, wanda ke haifar da jinkirin daidaitawar kunnawa da allurar mai. A lokacin sanyi, ana iya buƙatar ƙoƙari da yawa ko ma gazawar gaba ɗaya na iya faruwa.
Tashin injin kwatsam yayin tuki: Musamman a yanayin zafi ko nauyi mai yawa, injin na iya tsayawa ba zato ba tsammani saboda matsalar sarrafawa, wanda ke ƙara haɗarin haɗurra.
Youdaoplaceholder0 Ƙayyadadden fitarwa na wutar lantarki : ECU zai shiga yanayin kariya daga matsala (yanayin rage gudu), yana iyakance saurin abin hawa (kamar har zuwa 80km/h) da kuma hana wasu ayyuka, wanda ke haifar da ƙarancin hanzari da wahalar hawa gangara.
Alamomin da suka saba faruwa sakamakon rashin aiki
Bayan an lalata na'urar firikwensin matsayin camshaft, abin hawa zai nuna nan take abubuwan da za a iya gani, waɗanda ke ƙara tabbatar da rashin yuwuwar tuƙi:
Youdaoplaceholder0 Saurin rashin aiki mara tabbas da girgiza mai tsanani : ECU ta kasa daidaita lokacin buɗewa da rufe bawul, wanda ke haifar da rashin daidaito tsakanin yawan shan ruwa da fitar da hayaki. Injin yana cikin yanayi kamar "silinda da ta ɓace", tare da manyan canje-canje a cikin saurin juyawa.
Youdaoplaceholder0 Lalacewar tattalin arzikin mai : Lokacin da ba daidai ba na allurar mai yana haifar da ƙonewa mara cikakke, yana ƙara yawan amfani da mai da kashi 10% zuwa 15%, kuma hayaki baƙi na iya fitowa daga bututun hayaki a lokaci guda.
Fitilar matsalar tana kunne : allon nuni zai nuna gargaɗin matsalar injin (kamar lambar P0011 ko P0340), yana nuna rashin daidaituwar tsarin.
