Datasheetka OBD-II DTC

HO2S Xakamaynta Kululeeyaha Heerka Sare (Bangiga 1 Sensor 3)

Maxay tani micnaheedu tahay?

Xeerkan Dhibaatada Baarista (DTC) waa koodh guud oo la isugu gudbiyo, taas oo macnaheedu yahay inay khuseyso baabuurta qalabaysan ee OBD-II, oo ay ku jiraan laakiin aan ku xaddidnayn Nissan, Mitsubishi, Mazda, Subaru, Toyota, VW, iwm. way kala duwan yihiin iyadoo ku xiran astaanta / moodeelka.

Dareemayaasha ogsijiinta leh walxaha kuleyliyaha ayaa si weyn loogu isticmaalaa matoorada casriga ah. Dareemayaasha ogsijiinta kuleyliyaha ah (HO2S) waa qalabyada uu isticmaalo PCM (Module Control Powertrain) si loo ogaado waxa ku jira ogsajiinta ee nidaamka qiiqa.

PCM -gu wuxuu adeegsadaa macluumaadka Bangiga 1, HO3S # 2, ugu horrayn si uu ula socdo hufnaanta beddelka kiciya. Qeyb muhiim ah oo ka mid ah shidmahan ayaa ah qeybta kululaynta. Halka baabuurta ka hor OBD II, dareeraha ogsajiintu wuxuu ahaa dareeme hal-silig ah, hadda waxay badiyaa yihiin dareemayaal afar-silig ah: laba u heellan dareeraha oksijiinta iyo laba u heellan qaybta kululaynta. Kuleyliyaha dareeraha oksijiin wuxuu yareeyaa waqtiga ay qaadato si loo gaaro loop xiran. PCM -gu wuxuu kormeeraa waqtiga uu shidaayo kululeeyaha. PCM -gu wuxuu kaloo si joogto ah u kormeeraa wareegyada kululeeyaha si uu u yeesho danab aan caadi ahayn ama, xaaladaha qaarkood, xitaa hadda aan caadi ahayn.

Kuleyliyaha dareeraha oksijiinta waxaa lagu xakameeyaa laba siyaabood midkood, iyadoo ku xiran astaanta gaariga. (1) PCM wuxuu si toos ah u koontaroolaa korantada kululeeyaha, ha ahaato si toos ah ama iyada oo loo marayo gudbinta dareeraha oksijiinta (HO2S), dhulkana waxaa laga keenaa dhulka wadaagga ah ee gaariga. (2) Waxaa jira fiyuus batari 12 -volt ah (B +) oo siiya 12 volts aaladda kululaynta mar kasta oo dabku shidan yahay, oo kululeeyaha waxaa maamula darawal ku jira PCM kaas oo koontaroola dhinaca dhulka ee wareegga kululeeyaha. ... Ogaanshaha midka aad haysato waa muhiim maxaa yeelay PCM -gu wuxuu ku dhaqaajin doonaa kululeeyaha xaalado kala duwan.

Haddii PCM -gu ogaado danab aan caadi ahayn oo aad u sarreeya wareegga kululeeyaha, P0044 ayaa dejin kara. Xeerkani kaliya wuxuu khuseeyaa kala bar wareegga kululaynta dareeraha ogsajiinta.

calaamadaha

Astaamaha lambarka dhibka ee P0044 waxaa ku jiri kara:

• Iftiinka MIL (Laambad Tusiyaha Cilladaysan)

Waxay u badan tahay, inaysan jiri doonin calaamado kale.

sababaha

Sababaha suurtogalka ah ee koodhka P0044 waxaa ka mid ah:

• Dareenka ogsajiinta kulul ee kulul ee # 3 safka 1.
• Ka Fur Wareegga Xakamaynta Kululeeyaha (12V PCM Systems Controlled)
• Gaaban ilaa B + (korantada batteriga) ee wareegga kontaroolka kululeeyaha (12V PCM nidaamyada la kontoroolo)
• Wareegga Dhulka Furan (12V PCM Systems Controlled)
• Gaaban ilaa dhulka wareegga kontoroolka kululeeyaha (nidaamyada dhulka PCM)

Xalalka suuragalka ah

Marka hore, si muuqaal ah u baar mashiinka saddexaad ee HO2S ee ku yaal Bank 1 iyo suunka fiilooyinka. Haddii uu jiro waxyeello gaaray dareeraha ama waxyeello soo gaartay fiilooyinka, hagaaji sida loogu baahdo. Ka fiiri fiilooyinka soo if -baxay halka xariggu ka galo dareeraha. Tani waxay badanaa keentaa daal iyo wareegyo gaagaaban. Hubi in fiilooyinka laga fogeeyo tuubada qiiqa. Dayactir xargaha ama beddel dareeraha haddii loo baahdo.

Haddii ay hagaagto, ka goo bangiga 3 # 1 HO2S oo hubi in 12 volts B + uu ku jiro matoorka (ama dhulka, iyadoo ku xiran nidaamka). Xaqiiji wareegga kontoroolka kululeeyaha (dhulka) waa dhawrsan yahay. Hadday sidaas tahay, ka saar dareeraha O2 oo iska hubi inay wax gaareen. Haddii aad marin u leedahay sifooyinka iska caabinta, waxaad isticmaali kartaa ohmmeter si aad u tijaabiso iska caabbinta aaladda kuleylka. Diidmada aan dhammaadka lahayn waxay tilmaamaysaa wareegga furan ee kululeeyaha. Beddel dareeraha ogsajiinta haddii loo baahdo.
