P048E Exhaust Gas Matsa lamba Control bawul Circuit High

Bayanan Bayani na OBD-II

Babban matakin sigina a cikin firikwensin / matsayin canzawa na bawul ɗin sarrafa matsin lamba

Mene ne wannan yake nufi?

Wannan Lambar Matsala Mai Rarraba Cutar Cutar (DTC) yawanci tana aiki ne akan duk motocin OBD-II sanye take da firikwensin bawul ɗin sarrafa matsin lamba. Wannan na iya haɗawa, amma ba'a iyakance ga, VW, Audi, Toyota, da dai sauransu Duk da yanayin gabaɗaya, ainihin matakan gyara na iya bambanta dangane da yin / ƙirar.

Kwarewar matsin lamba ta shayewa (EPC) shine bawul na SOLENID wanda ake amfani dashi don tsara matsin lamba a yanayin zafi. Wannan yana taimakawa wajen ƙara dumama ɗakin fasinja, yana inganta farawa sanyi da kuma kawar da gilashin iska.

A mafi yawan lokuta, tsarin sarrafa wutar lantarki (PCM) yana amfani da bayanai daga firikwensin baya (EBP) firikwensin, firikwensin zafin iska (IAT), da firikwensin matsi mai yawa (MAP) don tantance ikon bawul. Idan PCM ya gano matsala tare da EPC ko IAT, zai kashe ECP. Ana samun ECP akan injunan diesel.

An saita P048E lokacin da PCM ta gano siginar da'irar keɓaɓɓiyar kula da matsin lamba. Wannan yawanci yana nuna siginar buɗewa.

Menene tsananin wannan DTC?

Girman wannan lambar matsakaita ne zuwa mai tsanani. Ana ba da shawarar gyara wannan lambar da wuri-wuri.

Misali na bawul mai sarrafa matsin lamba:

Menene wasu alamomin lambar?

Alamomin lambar matsala P048E na iya haɗawa da:

• Duba Hasken Injin
• Ƙaruwar hayaki
• Ayyukan injin mara kyau
• Hard fara

Mene ne wasu abubuwan da ke haifar da lambar?

Dalilan wannan lambar na iya haɗawa da:

• Bawul ɗin sarrafa iskar gas ɗin yana da lahani
• Matsalolin wayoyi
• PCM mara lahani

Menene wasu matakai don warware matsalar P048E?

Fara ta hanyar duba bawul ɗin sarrafa matsin lamba 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 duba 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.

Duba wayoyi

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 solenoid

Cire haɗin keɓaɓɓen. Yi amfani da saiti na multimeter na dijital zuwa ohms don duba juriya na solenoid. Don yin wannan, haɗa mita tsakanin tashar B + solenoid da tashar ƙasa. Kwatanta juriya da aka auna tare da ƙayyadaddun gyaran masana'anta. Idan mitar ta nuna karatun da ba a bayyana ba ko kuma daga cikin kewayon (OL) da ke nuna kewaya mai buɗewa, yakamata a maye gurbin tafin tafin.

Duba gefen wadata na kewaye

Tabbatar cewa motar tana zaune na aƙalla ƴan sa'o'i (zai fi dacewa da dare) kuma tana da sanyi. Cire mai haɗin solenoid. Tare da kunnan abin hawa, yi amfani da multimeter na dijital da aka saita zuwa ƙarfin lantarki na DC don bincika ƙarfin solenoid (yawanci 12 volts). Don yin wannan, haɗa madaidaicin jagorar mitar zuwa ƙasa kuma madaidaiciyar mitar ta jagoranci zuwa tashar B+ solenoid a gefen kayan doki na mai haɗin. Idan babu irin ƙarfin lantarki, haɗa na'urar juriya (a kashe wuta) tsakanin tashar B+ akan mahaɗin solenoid da tashoshin wutar lantarki na solenoid 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 samar da wutar lantarki ta EPC akan 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. Cire haɗin keɓaɓɓen. Haɗa mita tsakanin tashar soloid na ƙasa da ƙasa. Idan lissafin yana karanta ƙimar lambobi, akwai ci gaba. Idan karatun mita bai wuce haƙuri ba (OL), akwai buɗaɗɗen da'irar tsakanin PCM da soloid ɗin da ke buƙatar a same shi kuma a gyara.

Tattaunawar DTC mai dangantaka

• A halin yanzu babu batutuwa masu alaƙa a cikin dandalin mu. Sanya sabon taken akan dandalin yanzu.

Kuna buƙatar ƙarin taimako tare da lambar P048E?

Idan har yanzu kuna buƙatar taimako tare da DTC P048E, aika tambaya a cikin sharhin da ke ƙasa wannan labarin.

NOTE. An ba da wannan bayanin don dalilai na bayanai kawai. Ba a yi nufin amfani da shi azaman shawarar gyara ba kuma ba mu da alhakin duk wani mataki da za ku ɗauka a kan kowane abin hawa. Duk bayanan da ke wannan shafin ana kiyaye su ta haƙƙin mallaka.
