Mene ne wannan yake nufi?

Wannan lambar watsawa ce gaba ɗaya wanda ke nufin ya dace da yawancin samfura / samfura daga 1996 zuwa gaba. Alamar kasuwanci na iya haɗawa da Ford, Dodge / Ram, Mercedes-Benz, Alfa Romeo, GMC, Chevrolet, Smart, VW, Audi, da dai sauransu.

Wannan Lambar Matsala ta Gano (DTC) P2084 tana nufin yanayin EGT (Exhaust Gas Temperature) firikwensin da ke cikin ƙasa na mai sauya catalytic. Burinsa kawai a rayuwa shine don kare transducer daga lalacewa saboda tsananin zafi.

P2084 yana nuna matsalar waje ko matsala da aka gano a cikin yanayin firikwensin zafin jiki na EGR akan bankin 1, firikwensin # 2. Wannan DTC P2084 yana nufin toshe # 1 (wanda shine gefen injin inda silinda # 1 yake).

Ana samun firikwensin EGT akan sabbin samfuran man fetur ko injunan dizal. Ba wani abu ba ne illa resistor mai sauƙin zafin jiki wanda ke juyar da zafin zafin iskar gas zuwa siginar ƙarfin lantarki don kwamfutar. Yana karɓar siginar 5V daga kwamfutar akan waya ɗaya kuma ɗayan waya tana ƙasa.

Misalin firikwensin zafin zafin gas na EGT:

Mafi girman yawan zafin jiki na iskar gas, ƙananan juriya na ƙasa, yana haifar da ƙarfin lantarki mafi girma - akasin haka, ƙananan zafin jiki, mafi girman juriya, yana haifar da ƙananan ƙarfin lantarki. Idan injin ya gano ƙananan ƙarfin lantarki, kwamfutar za ta canza lokacin injin ko rabon mai don kiyaye zafin jiki a cikin kewayon karɓuwa a cikin mai sauya.

A cikin man dizal, ana amfani da EGT don ƙayyade lokacin farfadowa na DPF (Diesel Particulate Filter) dangane da hauhawar zafin jiki.

Idan, lokacin cire mai jujjuyawar, an shigar da bututu ba tare da mai juyawa ba, to, a ƙa'ida, ba a bayar da EGT ba, ko, idan akwai, ba zai yi aiki daidai ba tare da matsin lamba ba. Wannan zai shigar da lambar.

• Tada motar ku nemo firikwensin. Don wannan lambar, tana nufin bankin 1 firikwensin, wanda shine gefen injin ɗin da ke ɗauke da silinda # 1. Yana tsakanin iskar shaye -shaye da mai juyawa ko, a yanayin injin dizal, saman Diesel Particulate Tace (DPF). Ya bambanta da firikwensin oxygen a cikin cewa shine toshe waya biyu. A kan abin hawa mai turbo, mai firikwensin zai kasance kusa da mashigar iskar gas mai turbo.
• Bincika masu haɗin haɗin don kowane rashin daidaituwa kamar lalata ko tashoshi marasa ƙarfi. Binciko alamar alade zuwa mai haɗawa kuma duba shi.
• Nemo alamun ɓataccen rufi ko wayoyin da aka fallasa waɗanda za su iya takaice zuwa ƙasa.
• Cire haɗin saman haɗin kai kuma cire firikwensin EGT. Duba juriya tare da ohmmeter. Duba duka tashoshi masu haɗawa. Kyakkyawan EGT zai sami kusan 150 ohms. Idan juriya yayi ƙasa sosai - ƙasa da 50 ohms, maye gurbin firikwensin.
• Yi amfani da na'urar bushewa ta gashi ko bindiga mai zafi da zafi firikwensin yayin kallon ohmmeter. Yakamata juriya ta faɗi yayin da firikwensin ke dumama da tashi yayin da yake sanyaya. Idan ba haka ba, canza shi.
• Idan komai yayi kyau a wannan lokacin, kunna maɓallin kuma auna ƙarfin lantarki akan kebul daga gefen motar. Mai haɗawa yakamata ya sami 5 volts. Idan ba haka ba, maye gurbin kwamfutar.

Wani dalili na saita wannan lambar shine cewa an maye gurbin mai jujjuyawa tare da tsarin dawowa. A yawancin jihohi, wannan doka ce da ba bisa ƙa'ida ba, wanda idan aka gano, babban laifi ne. Ana ba da shawarar duba dokokin gida da na ƙasa dangane da zubar da wannan tsarin saboda yana ba da damar gurɓataccen iska zuwa yanayi. Yana iya aiki, amma kowa yana da alhakin yin nashi ɓangaren don kiyaye tsabtace muhallinmu ga tsararraki masu zuwa.

Har sai an gyara wannan, ana iya sake saita lambar ta hanyar siyan resistor na 2.2 ohm daga kowane kantin kayan lantarki. Kawai zubar da firikwensin EGT kuma haɗa resistor zuwa mai haɗa wutar lantarki a gefen motar. Kunsa shi da kaset kuma kwamfutar zata tabbatar cewa EGT tana aiki yadda yakamata.
