Maxay tani micnaheedu tahay?
Kani waa koodh guud oo la isugu gudbiyo taas oo macnaheedu yahay inay khuseyso dhammaan baabuurta OBD-II laga bilaabo 1996 wixii ka dambeeya. Calaamadaha baabuurka waxaa ku jiri kara laakiin kuma koobna Mazda, Ford, VW, Mercedes Benz, iwm. Hase yeeshee, tallaabooyinka xallinta dhibaatooyinka gaarka ah way kala duwanaan karaan iyadoo ku xiran baabuurka.
Xeerkan Dhibaatada Baadhista (DTC) P2274 wuxuu ku saabsan yahay ka-beddel-ka-beddelaha O2 (ogsijiin) dareeraha barta # 1, dareeraha # 3. Dareemahan bisadda-dambe ayaa loo adeegsadaa si loola socdo wax-ku-beddelka dabaysha. Shaqada beddeluhu waa inuu yareeyo qiiqa qiiqa. DTC -daani wuxuu dejiyaa marka PCM -ku ka ogaado calaamadda ka timaada dareeraha O2 sida caatada ku dhegtay ama si khaldan loo qaabeeyey.
DTC P2274 waxaa loola jeedaa dareeraha labaad ee hoose (ka dib beddelka labaad ee catalytic), dareeraha #3 ee bangiga #1. Bangiga #1 waa dhinaca matoorka ka kooban dhululubo #1.
Xeerkani wuxuu asal ahaan kuu sheegayaa in ishaarta ay bixisay dareere oyxgen gaar ahi ay ku dhegtay isku darka caatada ah (taas oo macnaheedu yahay hawo aad u badan ayaa ku jirta qiiqa).
Dareenka oksijiinta caadiga ah O2: 
calaamadaha
Fursadaha ayaa ah, ma ogaan doontid wax arrimo maarayn ah maadaama tani aysan ahayn dareeme # 1. Waxaad ogaan doontaa in Iftiimiyaha Tilmaamaha Cilladdu (MIL) uu daaran yahay. Si kastaba ha ahaatee, mararka qaarkood, matoorku si joogto ah ayuu u shaqayn karaa.
Sababaha macquulka ah
Sababaha DTC -kan waxaa ku jiri kara:
- Gaaska qiiqa ayaa ku daata meel u dhow dareeraha O2
- Dareenka HO2S2 ee wasakhaysan ama cilladaysan (dareeraha 3)
- HO2S2 Wareegga / Dhibaatada Wareegga
- Rakibaadda lacag la'aanta ah ee dareeraha HO2S2
- Cadaadis shidaal oo aan sax ahayn
- Shidaalka shidaalka ee cilladaysan
- Dillaaca qaboojiyaha matoorka
- Waalka solenoid nadiifiye ee cilladaysan
- PCM amarka
Hababka ogaanshaha iyo dayactirka
Si muuqaal ah u fiiri fiilooyinka iyo isku xirayaasha si ay u daxaladaan, fiilooyinka la xoqay / la tirtiray, biinanka taayirrada qaloocan, gubtay iyo / ama fiilooyin gooyay. Dayactir ama beddel markii loo baahdo.
Hubi in qiiqa ka daatay iyo dayactir haddii loo baahdo.
Adigoo isticmaalaya mitir volt volt ohm (DVOM) oo loo dhigay ohms, tijaabi isku xirayaasha suunka si iska caabin ah. Isbarbar dhig tilmaamaha soo -saaraha. Beddel ama dayactir haddii loo baahdo.
Haddii aad marin u leedahay aaladda baarista sare, u isticmaal si aad ula socoto akhrinta dareeraha sida uu arkay PCM (mashiinka ku shaqeeya heerkulka hawlgalka caadiga ah ee qaabka loop xiran). Dareemaha oksijiin ee kulul ee kulul (HO2S) ayaa sida caadiga ah arka isbeddellada danab ee u dhexeeya 0 iyo 1 volt, waayo DTC -kan waxaad u badan tahay inaad arki doonto danab ku dhegan 0 V. Wareegidda mishiinka waa inay keentaa in danab shidmahu is beddelo (falcelin).
Dayactirka ugu badan ee DTC -gu waa hawo hawo -baxaysa, dhibaato la xiriirta dareeraha / fiilooyinka fiilooyinka, ama dareeraha laftiisa. Haddii aad beddesho dareerahaaga O2, soo iibso OEM (sumadda sumadda) dareeraha si aad u hesho natiijooyinka ugu fiican.
Haddii aad ka saarto HO2S, ka hubso wasakhda ka timaadda shidaalka, saliidda mishiinka, iyo qaboojiyaha.
Fikradaha kale ee xallinta dhibaatooyinka: Isticmaal tijaabiye cadaadiska shidaalka, ka hubso cadaadiska shidaalka ee waalka Schrader ee tareenka shidaalka. Isbarbar dhig soo -saaraha soo -saaraha. Fiiri waalka solenoid -ka sifeeya. Kormeer cirbadaha shidaalka. Fiiri marinnada qaboojiyaha si ay u dillaacaan.
