Mene ne wannan yake nufi?
Wannan lambar watsawa ce gaba ɗaya wanda ke nufin ya shafi duk motocin OBD-II daga 1996 zuwa gaba. Alamar mota na iya haɗawa amma ba'a iyakance ta ga Mazda, Ford, VW, Mercedes Benz, da dai sauransu.
Wannan Lambar Matsalar Bincike (DTC) P2274 ta shafi firikwensin Canjin Canjin O2 (oxygen) akan toshe # 1, firikwensin # 3. Ana amfani da wannan firikwensin bayan-cat don saka idanu kan ingancin mai juyawa. Aikin mai juyawa shine rage fitar da hayaƙi. Wannan DTC yana saita lokacin da PCM ta gano siginar daga firikwensin O2 azaman makale ko mara nauyi.

Hanyoyin bincike da gyara
Duba ido da wayoyi da masu haɗawa don lalata, wayoyi da aka goge / cire / cirewa, lanƙwasa / lanƙwasa wayoyi, ƙonawa da / ko ƙetare wayoyi. Gyara ko maye gurbin yadda ake buƙata.
Bincika magudanan ruwa da gyara idan ya cancanta.
Ta amfani da mitar volt ohm mita (DVOM) da aka saita zuwa ohms, gwada haɗin haɗin haɗin don juriya. Kwatanta da ƙayyadaddun masana'anta. Sauya ko gyara kamar yadda ya cancanta.
Idan kuna da damar yin amfani da kayan aikin bincike na ci gaba, yi amfani da shi don saka idanu karatun firikwensin kamar yadda PCM ya gani (injin da ke aiki a yanayin zafin aiki na yau da kullun a cikin yanayin madauki). Na'urar firikwensin iskar oxygen mai raɗaɗi (HO2S) galibi tana ganin sauye -sauyen ƙarfin lantarki tsakanin 0 zuwa 1 volt, don wannan DTC da alama zaku iya ganin wutar lantarki ta makale a 0 V. Juya injin ɗin yakamata ya sa ƙarfin firikwensin ya canza (amsa).
Gyaran da aka saba yi don wannan DTC shine fitar da iska mai ƙarewa, matsala tare da firikwensin / wayoyi, ko firikwensin da kansa. Idan kuna maye gurbin firikwensin O2 ɗin ku, sayi firikwensin OEM (sunan alama) don kyakkyawan sakamako.
Idan kuna cire HO2S, bincika don gurɓatawa daga mai, man injin, da mai sanyaya ruwa.
Sauran ra'ayoyin warware matsala: Yi amfani da gwajin matatun mai, duba matsin mai a bawul ɗin Schrader akan layin dogo. Kwatanta da ƙayyadaddun masana'anta. Duba bawul ɗin solenoid bawul. Duba masu allurar mai. Duba hanyoyin coolant don leaks.
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 P2274?
Idan har yanzu kuna buƙatar taimako tare da DTC P2274, 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.
