Wannan Lambar Matsalar Bincike (DTC) lambar watsawa ce gaba ɗaya, wanda ke nufin ya shafi motocin OBD-II sanye da kayan firikwensin mai (Chevrolet, Ford, GMC, Chrysler, Toyota, da sauransu). Duk da yanayin gabaɗaya, ainihin matakan gyara na iya bambanta dangane da yin / ƙirar. Abin mamaki, da alama wannan lambar ta fi yawa akan motocin GM (GMC, Chevrolet, da sauransu) kuma yana iya kasancewa tare da lambar P018C da / ko wasu lambobin a lokaci guda.

Yawancin motocin zamani an sanye su da firikwensin matsin lamba (FPS). FPS yana ɗaya daga cikin manyan abubuwan da aka shigo da su zuwa tsarin sarrafa wutar lantarki (PCM) don sarrafa famfon mai da / ko injector na mai.

Na'urar firikwensin mai shine nau'in firikwensin da ake kira transducer. Irin wannan firikwensin yana canza juriya na ciki tare da matsa lamba. Yawancin lokaci ana hawa FPS zuwa ko dai layin dogo ko layin mai. Yawancin lokaci akwai wayoyi uku masu zuwa FPS: tunani, sigina da ƙasa. Na'urar firikwensin yana karɓar ƙarfin tunani daga PCM (yawanci 5 volts) kuma yana mayar da ƙarfin amsawa wanda yayi daidai da matsa lamba mai.

Game da wannan lambar, "B" yana nuna cewa matsalar tana tare da wani ɓangare na sarkar tsarin ba tare da takamaiman alama ko sashi ba.

An saita P018B lokacin da PCM ta gano matsalar aiki tare da firikwensin matsin lamba. Lambobin da aka haɗa sun haɗa da P018A, P018C, P018D, da P018E.

Hanyoyin bincike da gyara

Fara ta hanyar duba firikwensin matatun mai da wayoyi masu alaƙa. Nemo hanyoyin haɗin kai, lalacewar wayoyi, da sauransu Idan an sami lalacewa, gyara yadda ake buƙata, share lambar kuma duba idan ta dawo. Sannan bincika bayanan sabis na fasaha (TSBs) don matsalar. Idan ba a sami komai ba, kuna buƙatar ci gaba zuwa binciken tsarin mataki-mataki.

Na gaba shine hanya gaba ɗaya kamar yadda gwajin wannan lambar ya bambanta daga abin hawa zuwa abin hawa. Don gwada tsarin daidai, kuna buƙatar komawa zuwa takaddar bincike na mai ƙira.

Kafin ci gaba, kuna buƙatar tuntuɓar zane -zanen kayan aikin masana'anta don tantance wace wace ce. Autozone yana ba da jagororin gyara kan layi kyauta don motoci da yawa kuma ALLDATA yana ba da biyan mota ɗaya.

Duba wani ɓangare na kewayon ƙarfin lantarki.

Tare da kunnan abin hawa, yi amfani da multimeter na dijital da aka saita zuwa ƙarfin lantarki na DC don bincika ƙarfin tunani (yawanci 5 volts) daga PCM. Don yin wannan, haɗa madaidaicin jagorar mitar zuwa ƙasa kuma madaidaiciyar mitar ta jagoranci zuwa tashar firikwensin B+ a gefen kayan doki na mai haɗawa. Idan babu siginar tunani, haɗa na'urar da aka saita zuwa ohms (ƙwaƙwalwa KASHE) tsakanin ma'aunin wutar lantarki akan firikwensin matsin man fetur da tashar wutar lantarki akan PCM. Idan karatun mita ya ƙare (OL), akwai buɗewa tsakanin PCM da firikwensin da ke buƙatar ganowa da gyarawa. Idan ma'aunin yana karanta ƙimar lamba, akwai ci gaba.

Idan komai ya yi kyau har zuwa wannan batu, za ku so ku duba idan wuta tana fitowa daga PCM. Don yin wannan, kunna wuta kuma saita mita zuwa wutar lantarki akai-akai. Haɗa ingantaccen jagorar mitar zuwa tashar wutar lantarki na PCM da mummunan gubar zuwa ƙasa. Idan babu wutar lantarki daga PCM, mai yiwuwa PCM yayi kuskure. Koyaya, PCMs ba kasafai suke kasawa ba, don haka yana da kyau ku ninka duba aikinku har zuwa wannan lokacin.

Duba ɓangaren ƙasa na kewaye.

Tare da ƙone abin hawa KASHE, yi amfani da resistor DMM don gwada ci gaba zuwa ƙasa. Haɗa mita tsakanin tashar ƙasa na mai haɗa firikwensin matattarar mai da ƙasa. Idan lissafin yana karanta ƙimar lambobi, akwai ci gaba. Idan karatun mita bai wuce haƙuri ba (OL), akwai kewaye kewaye tsakanin PCM da firikwensin da ke buƙatar kasancewa da gyara.

Duba ɓangaren kewayon siginar dawowa.

Idan mai nuna alama ba ya da iyaka (OL), akwai buɗewar kewayawa tsakanin PCM da firikwensin da ke buƙatar gyara. Idan ma'aunin yana karanta ƙimar lamba, akwai ci gaba.

Kwatanta firikwensin matsin lamba na mai tare da ainihin matsin mai.

Gwajin da aka yi har zuwa wannan lokacin yana nuna cewa da'irar firikwensin matsin lamba tana da kyau. Sa'an nan kuma za ku so ku gwada firikwensin da kansa akan ainihin matsin lamba na mai. Don yin wannan, da farko haɗa ma'aunin matsa lamba na inji zuwa layin dogo. Sannan haɗa kayan aikin abin dubawa zuwa abin hawa kuma zaɓi zaɓin bayanan FPS don dubawa.
