P0139 - HO2S Bank 1 Sensor 2 O1 Dareemka Wareegga Gaabis ah ee Jawaabta (B2SXNUMX)

P0139 - Sharaxaada koodhka dhibaatada

Dareemaha oksijiinta kuleyliyaha ah 2 (ho2s), hoos-u-socodka saddex-geesoodka katalytik beddelka (maxaan), wuxuu la socdaa heerka ogsijiinta ee gaasaska qiiqa ee bangi kasta oo dhululubo ah. Waxqabadka ugu wanaagsan ee kicinta, hawada ilaa saamiga shidaalka (saamiga hawo-shidaalka) waa in lagu hayaa meel u dhow saamiga stoichiometric ee ku habboon. Korontada wax soo saarka ee dareeraha ho2s ayaa si lama filaan ah isu beddela meel u dhow saamiga stoichiometric.

Qaybta kontoroolka matoorka (ECM) ayaa hagaajiya wakhtiga lagu duro shidaalka si saamiga hawadu uu ugu dhawaado stoichiometric. Iyada oo laga jawaabayo joogitaanka ogsijiinta ee gaaska qiiqa, dareeraha ho2s wuxuu abuuraa danab ah 0,1 ilaa 0,9 V. haddii oksijiinta ku jirta gaasta qiiqa ay korodho, saamiga hawadu iyo shidaalka ayaa noqda mid caato ah.

Qaybta ECM waxay tarjumeysaa isku dhafka caatada ah marka korantada dareeraha ho2s uu ka yar yahay 0,45V. haddii oksijiinta ku jirta gaasaska qiiqa ay yaraato, saamiga hawada iyo shidaalka ayaa noqda mid hodan ah. Qaybta ECM waxay tarjumeysaa calaamada hodanka ah marka korantada dareeraha ho2s uu dhaafo 0,45V.

Waa maxay macnaha DTC P0139?

Koodhka dhibka P0139 waxa uu la xidhiidha dareemaha ogsijiinta ee dhinaca dareewalku waxa aanu tilmaamayaa in saamiga hawada iyo shidaalka matoorka aan si sax ah loogu hagaajin dareeraha ogsijiinta ama calaamada ECM. Tani waxay dhici kartaa ka dib marka matoorku kululaado ama marka matoorku aanu si caadi ah u shaqaynayn. "Bank 1" waxa loola jeedaa bangi dhululubo oo ka kooban dhululubo #1.

Xeerka P0139 waa heerka caadiga ah ee OBD-II wuxuuna tilmaamayaa in bangiga 1 dareeraha ogsijiinta, dareemaha 1, aanu muujin hoos u dhac danab ah oo ka yar 0,2 volts muddo 7 ilbiriqsi ah inta lagu guda jiro muddada xidhitaanka shidaalka. Fariintani waxay muujinaysaa jawaab celin dareemaha gaabis ah sida lagu ogaaday Module Control Engine (ECM).

Sababaha macquulka ah

Koodhka P0139, ECM waxay yaraynaysaa sahayda shidaalka ee mishiinka inta lagu jiro hoos u dhaca mishiinka iyo dhammaan dareemayaasha O2 waa inay ku jawaabaan koronto wax soo saar ah oo ka yar 2 V, taasoo muujinaysa oksijiinta sare ee gaaska qiiqa. Koodhka qaladka ayaa la dejiyaa haddii bangiga 2 O1 dareeraha, dareemayaasha 1, uusan ka jawaabin jarista shidaalka 7 ilbiriqsi ama ka badan.

Tani waxaa laga yaabaa inay sababto

• Shidaalka xad-dhaafka ah ee qulqulka gaasta qiiqa sababtoo ah qulqulka suurtagalka ah ee nidaamka duridda shidaalka,
• cilladda dareemaha ogsijiinta kuleylkeeda dambe, xannibaadda 1,
• Dareemaha ogsijiinta ee kuleylaha dambe ee bangiga 1 xadhkaha fiilooyinka (furan ama gaaban),
• dhibaatooyinka xiriirka korantada ee batteriga 1 ee kuleylaha dambe ee kuleylka,
• cadaadiska shidaalka oo aan ku filnayn,
• cirbadaha shidaalka oo khaldan,
• hawo ka daadato qaadashada,
• cilladaha ku jira unugga dareeraha ogsijiinta oo leh kuleyl kale,
• Dareemaha ogsijiinta ee kuleylaha dambe ee bangiga 1 xadhkaha fiilooyinka (furan ama gaaban),
• cilladda wareegga 1 ee dareeraha ogsijiinta ee kuleylaha dambe,
• cadaadiska shidaalka oo aan ku filnayn,
• cirbadaha shidaalka oo khaldan iyo cilad suurto gal ah oo ku timaada hawo soo daadasha,
• iyo sidoo kale gaaska qiiqa daadanaya.

Waa maxay calaamadaha koodka P0139?

• Matoorku waxa laga yaabaa inuu istaago ama uu xumaado shidaal xad dhaaf ah awgeed.
• Matoorku waxa uu muujin karaa labalabayn inta lagu jiro dardargelinta ka dib hoos u dhaca.
• Nalka mashiinka hubinta (ama nalka dayactirka mishiinka) ayaa shid.
• Isticmaalka shidaalka oo sarreeya.
• Xaddiga qiiqa xad dhaafka ah ee nidaamka qiiqa.

Sidee lagu gartaa koodka P0139?

1. Sawirka codes iyo diiwaanada xogta, ka soo qaadashada macluumaadka jir.
2. La soco akhriska dareeraha O2 si aad u go'aamiso haddii danabku hoos uga dhaco 0,2 V inta lagu jiro hoos u dhaca.
3. Hubi cadaadiska shidaalka ee injiinka si uu u daadanayo nidaamka duritaanka shidaalka.
4. Hubi in dareeraha O2 aanu ku wasakhaysan walxaha dibadda sida qaboojiyaha ama saliidda.
5. Ka hubi nidaamka qiiqa burburka ama dhibaatooyinka, gaar ahaan aagga beddelka tamarta.
6. Samee tijaabooyinka ay bixiso soo saaraha si loo helo ogaanshaha dheeraadka ah.

Khaladaadka ogaanshaha

Si aad isaga ilaaliso ogaanshaha khaldan, raac tilmaamahan fudud:

Haddii labada dareemayaal (1 iyo 2) ee isla dhinaca matoorka ah ay gaabis yihiin inay ka jawaabaan, fiiro gaar ah u yeelashada duritaanka shidaalka ee suurtogalka ah ee bangiga ugu horreeya ee mishiinka.

Kahor inta uusan code-kani dhicin, cilad ku samee wixii dhibaato ah ee suurtogalka ah ee ku dheggan waalka ceejinta ee laga yaabo in uu farageliyo habka xidhitaanka shidaalka.

Hubi xaaladda beddelaha katalytic-ga burburka sababi kara in dareemaha uu xumaado.

Sidee khatar u tahay koodka dhibaatadu P0139?

Xeerkani wuxuu muujinayaa in xitaa haddii dareemaha uu wanaagsan yahay, matoorku wali wuxuu sii wadaa inuu keeno shidaalka inta lagu jiro hoos u dhaca, xitaa marka aan loo baahnayn. Tani waxay horseedi kartaa korodhka isticmaalka shidaalka iyo xitaa matoorka oo istaaga marka la joojiyo haddii shidaal badan uu soo galo dhululubada.

ECM (Module kantaroolka matoorka) ma awoodo inuu xakameeyo daminta shidaalka haddii kuwa shidaalka lagu shubo aan la xidhin, taas oo keeni karta isticmaalka shidaal xad dhaaf ah.

Dayactirkee ayaa hagaajin doona koodka P0139?

Beddelka dareeraha O2 ee bangiga 1 dareeraha 1 waa in la sameeyaa oo kaliya ka dib marka la dhammeeyo dhammaan hubinta nidaamka shidaalka iyo qiiqa kale.

1. Marka hore, hubi xaalada nidaamka shidaalka oo beddel cirbad shidaal oo soo daadanaya haddii la helo.
2. Ku beddel qalabka kicinta ee dareemaha hortiisa haddii ay cilladaysan tahay.
3. Kahor intaadan bedelin dareeraha O2, nadiifi cirbadaha oo hubi in wixii daadanaya la hagaajiyay.

Dareenka O2 oo tartiib tartiib ah ayaa laga yaabaa inay sabab u tahay gabowga iyo wasakhowga. Mar haddii dareeme O2 uu cabbiro ogsajiinta ku jirta gaaska qiiqa, kayd kasta ama wasakh kasta oo dusha sare ah ayaa carqaladayn karta cabbirka saxda ah. Xaaladahan oo kale, nadiifinta ama beddelka dareemaha waxay gacan ka geysan kartaa soo celinta shaqadeeda waxayna hagaajinaysaa jawaab-celinta isbeddelka gaaska qiiqa.
