I-P0140 Ukungasebenzi komsebenzi kumjikelezo we-oxygen sensor (B2S1)

Ikhodi Yenkinga ye-OBD-II - P0140 - Ishidi Ledatha

• I-P0140 Ukungasebenzi komsebenzi kumjikelezo we-oxygen sensor (B2S1)
• Awukho umsebenzi kusekethe yenzwa (block 1, inzwa 2)

Isho ukuthini i-DTC P0140?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezihlomele i-OBD-II. Yize kuvamile emvelweni, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli.

Imojula yokulawula i-powertrain (PCM) inikeza ireferensi engu-45 V kunzwa komoyampilo. Lapho inzwa ye-O2 ifinyelela izinga lokushisa lokusebenza, ikhiqiza i-voltage ezohluka kuye ngokuqukethwe komoya-mpilo wamagesi okukhipha umoya. I-lean exhaust ikhiqiza i-voltage ephansi (ngaphansi kuka-45 V), kanti i-exhaust ecebile ikhiqiza amandla aphezulu (ngaphezu kuka-45 V).

Izinzwa ze-O2 ebhange elithile, elilebulwe ngokuthi “inzwa 2” (njengale), zisetshenziselwa ukuqapha ukukhishwa kwekhabhoni. Uhlelo lwezindlela ezintathu lwe-catalyst (TWC) (i-catalytic converter) lusetshenziselwa ukulawula amagesi akhipha umoya. I-PCM isebenzisa isignali etholwe ku-2 inzwa ye-oxygen (# 2 ibonisa ingemuva lesiguquli se-catalytic, # 1 ikhombisa isiguquli sangaphambili) ukucacisa ukusebenza kahle kwe-TWC. Ngokuvamile le nzwa izoshintsha phakathi kwevolthi ephezulu nephansi ngokuphawulekayo kancane kunenzwa yangaphambili. Lokhu kuhle. Uma isignali etholwe ngemuva (# 2) inzwa ye-O2 ibonisa ukuthi i-voltage ibambelele kububanzi obungu-425 V kuya ku-474 V, i-PCM ithola ukuthi inzwa ayisebenzi futhi isetha le khodi.

Izimpawu ezingaba khona

Ukukhanya Kwenjini Yokuhlola (CEL) noma Ukukhanya Kwenkomba Engasebenzi (MIL) kuzokhanyisa. Ngeke kube nezinkinga eziphawulekayo zokusingatha ngaphandle kwe-MIL. Isizathu siwukuthi: inzwa ye-oxygen ngemuva noma ngemva kwesiguquli se-catalytic ayithinti ukunikezwa kukaphethiloli (lokhu kuhlukile ku-Chrysler). IQAPHELA kuphela ukusebenza kahle kwesiguquli se-catalytic. Ngenxa yalesi sizathu, cishe ngeke uqaphele izinkinga zenjini.

• Inkomba iyakhanyisa ekhombisa inkinga.
• Umsebenzi onzima wenjini
• Ukungabaza (uma kushesha ngemva kwesigaba sokunciphisa)
• I-ECM ilahlekelwa amandla ayo okugcina isilinganiso esifanele somoya/samafutha ohlelweni lukaphethiloli (lokhu kungase kubangele izimpawu zokushayela ezishintshashintshayo).

Izimbangela zephutha P0140

Izizathu zokuvela kwekhodi ye-P0140 zimbalwa kakhulu. Angaba yinoma yikuphi kokulandelayo:

• Isekhethi emfishane kumjikelezo we-heater kunzwa ye-O2. (Imvamisa idinga ukushintshwa kwefuse yesekethe ye-heater futhi ebhokisini le-fuse)
• Isifunda esifushane kumjikelezo wesiginali kunzwa ye-O2
• Ukuncibilika kwesixhumi sehhanisi noma izintambo ngenxa yokuxhumana nesistimu yokukhipha umoya
• Ukungena kwamanzi kusixhumi sezintambo zezintambo noma isixhumi se-PCM
• I-PCM engalungile

Izixazululo ezingenzeka

Lena inkinga eqondile futhi akufanele kube nzima ukuyixilonga.

Qala injini kuqala bese uyifudumeza. Ngethuluzi lokuskena, bheka i-Bank 1, inzwa 2, i-O2 Sensor Voltages. Ngokuvamile, i-voltage kufanele ishintshe kancane phezulu nangaphansi kwama-volts angu-45. Uma kunjalo, cishe inkinga ingeyesikhashana. Kuzodingeka ulinde kuze kube yilapho inkinga itholakala ngaphambi kokuthi uyihlole ngokunembile.

Nokho, uma ingagudluki noma ibambeke, landela lezi zinyathelo: 2. Misa imoto. Hlola ngeso lengqondo i-Bank1,2 isixhumi sehhanisi ukuze sincibilike noma sihuzuke ihhanisi noma isixhumi. Lungisa noma shintsha njengoba kudingeka 3. Khanyisa isibani, kodwa cisha injini. Nqamula isixhumi senzwa ye-O2 bese uhlola ama-volts angu-12 kumjikelezo wamandla we-heater kanye nokubeka phansi okufanele endaweni yesekhethi ye-heater. a. Uma engekho amandla okushisa angu-12V atholakalayo, hlola amafuse esekethe avulekile alungile. Uma i-fuse yesekethe ye-heater ishaywa, kungacatshangwa ukuthi i-heater enesici ku-o2 sensor ibangela ukuthi i-fuse yesekethe ye-heater ivuthe. Faka esikhundleni inzwa nefuse bese uhlola kabusha. b. Uma kungekho mhlabathi, landelela isekethe futhi uhlanze noma ulungise isekethe yomhlabathi. 4. Khona-ke, ngaphandle kokuxhuma isixhumi, hlola i-5V kumjikelezo wereferensi. Uma kungenjalo, hlola i-5V kusixhumi se-PCM. Uma i-5V ikhona kusixhumi se-PCM kodwa ingekho kusixhumi senzwa ye-o2 yeharness, kukhona okuvulekile noma okufushane kuntambo yesithenjwa phakathi kwe-PCM nesixhumi senzwa ye-o2. Nokho, uma kungekho volts angu-5 kusixhumi se-PCM, i-PCM cishe inephutha ngenxa yesifunda esifushane sangaphakathi. Shintshanisa amasheya PCM. ** (QAPHELA: Kumamodeli e-Chrysler, inkinga evamile ukuthi isifunda esiyisethenjwa se-5V singafinyezwa yinoma iyiphi inzwa esemotweni esebenzisa isignali yesithenjwa engu-5V. Vele uvale inzwa ngayinye ngesikhathi kuze kuvele i-5V. inzwa oyinqamulile iyinzwa emfishane, ukuyishintsha kufanele kusule isifunda esifushane sesithenjwa esingu-5V.) 5. Uma wonke ama-voltage nezizathu zikhona, buyisela inzwa ye-O1,2 kuYunithi 2 bese uphinde ukuhlola.

IYENZA KANJANI IKHODI YE-MCHHANIC DIAGNOSTIC P0140?

• Iskena amakhodi namadokhumenti, ithwebula idatha yozimele
• Iqapha idatha yenzwa ye-O2 ukuze ibone ukuthi i-voltage ihamba phezulu noma ngaphansi kuka-410-490mV.
• Iqapha idatha yenzwa ye-MAF ukuze iphendule izinguquko ze-throttle ngokuya ngokucaciswa.
• Ilandela izivivinyo zezindawo ezithile zomkhiqizi ukuze kuqhutshekwe nekhodi yokuxilonga (ukuhlola kuyehluka phakathi kwabakhiqizi)

AMAPHUTHA AVAMILE LAPHO KUHLOLWA IKHODI P0140?

• Ngaphambi kokushintsha inzwa ye-O2, hlola inzwa yokugeleza komoya enkulu ngomonakalo nokungcoliswa.

Ukuntuleka kokuphendula kwenzwa ye-O2 kungabangelwa ukungcoliswa kwenzwa yokugeleza komoya obuningi futhi ingabalwa inani lomoya ongena enjini ohlangothini lokuthatha.

IYIZINKANI IKHODI P0140?

• Le khodi ingase ihlotshaniswe nezinkinga ngenzwa yokugeleza komoya obuningi, okudingekayo ukubala kahle inani lomoya ongena enjinini. Kanye nezinzwa ze-O2, ukwehluleka kwanoma iyiphi yalezi zingxenye kuzobangela i-ECM ukuba ibale kabi isilinganiso somoya/samafutha enjinini.
• I-ECM ingase ilahlekelwe ukulawula noma ithole idatha engalungile evela kuzinzwa ezifana nenzwa yokugeleza komoya enkulu noma inzwa ye-O2 uma ingaphakathi kokucaciswayo kodwa ingalungile.

Lezi zinkinga zingaholela ekuziphatheni kokushayela ngezikhathi ezithile okungaphazamisa ukuphepha kwabashayeli.

YIKUPHI UKULUNGISA ONGALUNGISA IKHODI P0140?

Ngemuva kokuskena nokusula wonke amakhodi wephutha nokuqinisekisa iphutha:

• Hlola inzwa ye-O2 ukuze ubone ukuthi iyashintsha yini njengoba ingxube kaphethiloli iya inotha.
• Hlola inzwa yokugeleza komoya omkhulu ukuze uthole ukufundwa okulungile ngokuhambisana nencazelo
• Miselela inzwa ye-O2 uma ingcolile noma yehluleka ukuhlolwa.
• Shintshanisa inzwa yokugeleza komoya obuningi uma ingcolile noma yehluleka ukuhlolwa.
• Hlanza inzwa yokugeleza komoya omkhulu ukuze ubone ukuthi ukufundwa kushintshile yini.

IMIBONO ENGEZIWE MAYELANA NEKHODI P0140 CABANGA

Ukuntula impendulo evela ku-O2 inzwa kungase kube ngenxa yokungcoliswa kwenzwa ye-MAF ngezinto ezifana namafutha avela kusihlungi somoya esifakwe uwoyela, njengazo zonke izinzwa. Lawa mafutha amboza inzwa futhi angayibangela ukuthi inganembile. Ukuhlanza inzwa kungase kuxazulule inkinga.
