Mene ne wannan yake nufi?

Wannan Lambar Matsalar Bincike (DTC) lambar watsawa ce gabaɗaya, wanda ke nufin ya shafi motocin OBD-II sanye take da firikwensin zazzabi mai sanyaya iska (Chevy, Ford, Toyota, Mitsubishi, Audi, VW, da sauransu) ... Duk da yanayin gabaɗaya, ainihin matakan gyara na iya bambanta dangane da yin / ƙirar.

Turbocharger shine ainihin famfon iska da ake amfani da shi don tilasta iska cikin injin. Akwai sassa biyu a ciki: injin turbine da compressor.

An makala injin turbine zuwa mashigin shaye-shaye inda iskar gas ke tuka shi. An haɗa kwampreso zuwa shan iska. Dukansu biyun suna haɗe da igiya, don haka yayin da injin turbine ke jujjuya shi, kwampressor kuma yana jujjuyawa, yana ba da damar shigar da iska a cikin injin. Mai sanyaya iska yana ba da cajin ɗaukar nauyi ga injin don haka ƙarin iko. A saboda wannan dalili, da yawa injuna suna sanye take da wani aftercooler, kuma aka sani da intercooler. Cajin na'urorin sanyaya iska na iya zama iska-zuwa ruwa ko na'urar sanyaya iska zuwa iska, amma aikinsu iri ɗaya ne - sanyaya iskar sha.

Ana amfani da Sensor Temperature Temperature Temperature Charge (CACT) don auna zafin jiki sabili da haka yawan iskar da ke fitowa daga cajin mai sanyaya iska. Ana aika wannan bayanin zuwa tsarin sarrafa wutar lantarki (PCM) inda aka kwatanta shi da yawan zafin iska (kuma a wasu lokuta injin zafin jiki na injin da zafin EGR) don tantance aikin mai sanyaya iska. PCM tana aika ƙarfin lantarki (yawanci 5 volts) ta hanyar tsayayyar ciki. Sannan yana auna ƙarfin lantarki don tantance zafin zafin cajin mai sanyaya iska.

Lura: Wani lokaci CACT wani ɓangare ne na firikwensin matsa lamba.

An saita P007D lokacin da PCM ta gano siginar firikwensin firikwensin mai sanyaya iska a kan toshe 1. Wannan yawanci yana nuna da'irar buɗewa. A kan injinan da ke da layuka da yawa na banki, banki 1 yana nufin shinge mai ɗauke da silinda # 1.

Ƙarfin lamba da alamu

Tsananin waɗannan lambobin suna tsaka -tsaki.

Abubuwan da ke iya haifar da wannan lambar P007D sun haɗa da:

• Raunin firikwensin
• Matsalolin wayoyi
• Lahani ko iyakance cajin mai sanyaya iska
• PCM mara lahani

Hanyoyin bincike da gyara

Fara da gani ta hanyar duba cajin firikwensin zafin iska mai sanyaya iska da haɗin haɗi. Nemo hanyoyin haɗin kai, lalacewar wayoyi, da dai sauransu Har ila yau, a duba cajin mai sanyaya iska da bututun iska. 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.

• Pre-gwada kewaye: yi amfani da kayan aikin dubawa don saka idanu cajin bayanan firikwensin iska mai sanyaya iska. Cire haɗin firikwensin CACT; ƙimar kayan aikin sikirin ya kamata ya faɗi zuwa ƙima sosai. Sa'an nan kuma haɗa jumper a fadin tashoshi. Idan kayan aikin dubawa yanzu yana nuna zafin zafin jiki, haɗin yana da kyau kuma ECM na iya gane shigarwar. Wannan yana nufin matsalar tana da alaƙa da firikwensin kuma ba batun kewaye ko PCM ba.
• Duba firikwensin: Cire haɗin cajin mai sanyaya firikwensin iska. Sannan auna juriya tsakanin tashoshi biyu na firikwensin tare da saita DMM zuwa ohms. Fara injin kuma duba ƙimar counter; yakamata ƙimar ta ragu a hankali yayin da injin ke dumama (duba ma'aunin zafin injin a kan dashboard don tabbatar injin yana kan zafin zafin aiki). Idan zafin injin ya hau amma juriya na CACT bai ragu ba, firikwensin yana da rauni kuma dole ne a maye gurbinsa.

Duba kewaye

• Duba gefen ƙarfin wutar lantarki na kewaye: tare da kunna wuta, yi amfani da multimeter na dijital da aka saita zuwa volts don duba ƙarfin lantarki na 5V daga PCM a ɗayan tashoshi biyu na cajin firikwensin iska mai sanyaya iska. Idan babu siginar nuni, haɗa mita da aka saita zuwa ohms (tare da kashe wuta) tsakanin tashar tunani akan CACT da tashar tashar wutar lantarki akan PCM. Idan karatun mita bai wuce haƙuri ba (OL), akwai kewaye kewaye tsakanin PCM da firikwensin da ke buƙatar kasancewa da gyara. Idan lissafin yana karanta ƙimar lambobi, akwai ci gaba.
• Idan komai yayi daidai har zuwa wannan lokacin, zaku so bincika idan 5 volts yana fitowa daga PCM a tashar tashar wutar lantarki. Idan babu ƙarfin lantarki na 5V daga PCM, PCM tabbas yana da lahani.
• Duba gefen ƙasa na kewaye: Haɗa mitar juriya (KASHE) tsakanin tashar ƙasa akan firikwensin zafin iska mai caji da tashar ƙasa 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. A ƙarshe, tabbatar da cewa PCM ɗin yana da kyau ta hanyar haɗa mita ɗaya zuwa tashar ƙasa ta PCM da ɗayan zuwa ƙasan chassis. Har yanzu, idan mitar ta karanta daga kewayon (OL), akwai buɗaɗɗen kewayawa tsakanin PCM da ƙasa wanda ke buƙatar ganowa da gyarawa.
