I-P0143 - I-OBD-II Ikhodi Yenkinga Incazelo Yobuchwepheshe

I-DTC P0143 ikhombisa i-voltage ephansi kusekethe ye-oxygen sensor 3 (ibhange 1).

Isho ukuthini ikhodi yephutha P0143?

Ikhodi yenkinga P0143 ibonisa inkinga ngenzwa ye-oxygen 3 (ibhange 1). Le khodi ivamise ukuhlotshaniswa ne-voltage ephansi ekuphumeni kwenzwa ye-oxygen.

Izizathu ezingenzeka

Ezinye izimbangela zekhodi yenkinga ye-P0143:

Inzwa yomoya-mpilo engasebenzi (O2) ebhange 1, inzwa 3.
Ukuxhumeka kukagesi okungalungile noma ukuphuka kwezintambo ezixhuma inzwa yomoya-mpilo kumojula yokulawula injini.
Ukungasebenzi kahle kwemojuli yokulawula injini (ECM).
Izinkinga zikagesi njengesekhethi emfishane noma intambo ephukile.
Izinkinga zekhwalithi yamafutha njengokungcoliswa noma umfutho wephethiloli onganele.
Izinkinga ngesistimu yomjovo kaphethiloli, njengomjovo onesici noma isilawuli sokucindezela uphethiloli.

Lezi zimbangela kufanele zicatshangelwe lapho kuxilonga i-DTC P0143.

Yiziphi izimpawu zekhodi yephutha? P0143?

Ezinye izimpawu ezingaba khona lapho ikhodi yenkathazo P0143 ikhona:

Ukwenyuka kokusetshenziswa kukaphethiloli: Inzwa ye-oxygen engalungile ingaholela ekuxubeni kukaphethiloli/komoya okungalungile, okunganyusa ukusetshenziswa kukaphethiloli.
Ukusebenza kwenjini okungazinzile: Uma ingxube kaphethiloli nomoya ingalungile, injini ingase isebenze kabi noma ibe mabi.
Impendulo esheshayo: Inzwa ye-oxygen engasebenzi kahle ingabangela injini ukuthi ihambe kancane uma icindezela i-pedal yegesi.
Ukwanda kokukhishwa kwezinto eziyingozi: Ukusebenza okungalungile kwenzwa ye-oxygen kungaholela ekwandeni kokukhishwa kwe-nitrogen oxides (NOx) nezinye izinto eziyingozi.
Ukusebenza okwehlisiwe: Uma injini ihamba izacile kakhulu noma inothe kakhulu ngenxa yenzwa ye-oxygen enephutha, lokho kungaholela ekusebenzeni kabi kwemoto.

Lezi zimpawu zingase zenzeke ngamazinga ahlukahlukene kuye ngenkinga ethile kanye nomthelela wayo ekusebenzeni kwenjini.

Indlela yokuxilonga ikhodi yephutha P0143?

Ukuze uhlole i-DTC P0143, landela lezi zinyathelo:

Ihlola ukuxhumana: Isinyathelo sokuqala ukuhlola konke ukuxhumana kukagesi okuhlobene nenzwa ye-oxygen. Qiniseka ukuthi zonke izixhumi zixhumeke ngokuvikelekile futhi azinawo umonakalo obonakalayo noma ukugqwala.
Ukuhlola izintambo: Hlola izintambo zokulimala, ukuphuka noma ukugqwala. Hlola izintambo kusukela kunzwa ye-oxygen kuya kusixhumi esihambisanayo kuyunithi yokulawula injini.
Ukuhlolwa kokumelana: Sebenzisa i-multimeter ukukala ukumelana nezintambo zenzwa ye-oxygen. Ukumelana kufanele kube ngaphakathi kwezicaciso zomkhiqizi.
Ukuhlola amandla kagesi: Usebenzisa i-multimeter, kala i-voltage ezintanjeni zenzwa ye-oxygen ngenjini egijima. I-voltage kufanele iguquguquke phakathi kwebanga elithile elishiwo umenzi.
Ukushintsha inzwa ye-oxygen: Uma konke ukuhlola okungenhla kungayivezi inkinga, kungase kudingeke ukuthi inzwa ye-oxygen ishintshwe. Qiniseka ukuthi inzwa entsha ihlangabezana nokucaciswa kwemoto yakho.
Ihlola Imojula Yokulawula Injini (ECM): Ezimweni ezingavamile, inkinga ingase ihlobane neyunithi yokulawula injini. Uma okunye ukuhlola kungavezi imbangela yokungasebenzi kahle, khona-ke ukuxilongwa okwengeziwe kwe-ECM kusetshenziswa okokusebenza okukhethekile kungase kudingeke.

Kubalulekile ukulandela imiyalelo yokulungisa ehlinzekwa ngumkhiqizi wemoto yakho futhi usebenzise amathuluzi afanele nezindlela zokuxilonga nokulungisa ngokuphepha. Uma ungenalo ulwazi lokwenza umsebenzi onjalo, kutuswa ukuthi uxhumane nomakhenikha wezimoto oqeqeshiwe.

Amaphutha okuxilonga

Lapho uxilonga i-DTC P0143, kungenzeka amaphutha alandelayo:

Ukuxilongwa kwezintambo okungalungile: Ukuchazwa okungalungile kwezimo zezintambo noma ukulinganisa okungalungile kokumelana noma i-voltage ezintanjeni zenzwa ye-oxygen kungase kuholele eziphethweni ezingalungile mayelana nembangela yokungasebenzi kahle.
Ukushintshwa okungalungile kwenzwa ye-oxygen: Ngaphambi kokufaka inzwa ye-oxygen, udinga ukuqinisekisa ukuthi inkinga ikunzwa hhayi ku-wiring noma iyunithi yokulawula injini. Ukushintsha okungalungile kungase kubangele izindleko ezengeziwe zokulungisa ngaphandle kokubhekana nomsuka wenkinga.
Ukweqa ezinye izizathu: Ngezinye izikhathi imbangela yekhodi ye-P0143 ingase ihlotshaniswe hhayi kuphela nenzwa ye-oxygen, kodwa futhi nezinye izinhlelo noma izingxenye zemoto, njengesistimu yokujova uphethiloli, uhlelo lokushisa, noma iyunithi yokulawula injini.
Ukuchazwa okungalungile kwedatha: Ukuqonda okungalungile kwedatha etholwe ngesikhathi sokuxilonga, noma ukuhumusha kwabo okungalungile, kungaholela esiphethweni esingalungile mayelana nezimbangela zokungasebenzi kahle kanye nezenzo ezingalungile zokuqeda.
Ukweqa izinyathelo zokuxilonga eziyisisekelo: Ukweqa izinyathelo zokuxilonga eziyisisekelo, njengokuhlola uxhumo, izintambo, ne-voltage yokukala noma ukumelana, kungase kuphumele ekulahlekeni kwemininingwane ebalulekile ethinta ukunemba kokuxilonga.

Kubalulekile ukulandela imihlahlandlela yokuxilonga ehlinzekwe ngumkhiqizi wemoto futhi usebenzise amathuluzi nezindlela ezifanele zokuxilongwa nokulungisa okunembile nangempumelelo. Uma ungenalo ulwazi lokwenza umsebenzi onjalo, kutuswa ukuthi uxhumane nomakhenikha wezimoto oqeqeshiwe.

Ibucayi kangakanani ikhodi yephutha? P0143?

Ikhodi yenkinga P0143 ikhombisa inkinga ngenzwa ye-oxygen. Nakuba lokhu kungase kubonise izinkinga ezihlukahlukene, ezifana nokusebenza kwenjini okungalungile noma ukusebenza kwesistimu yokulawula ukungcola okunganele, ngokuvamile akubalulekile noma kuphuthumayo. Nokho, ukuyishaya indiva kungaholela ekwehliseni ukonga kukaphethiloli, ukusebenza kabi kwenjini kanye nokwanda kokukhishwa kwezinto eziyingozi endaweni ezungezile. Ngakho-ke, kunconywa ukuxilonga nokulungisa le nkinga ngokushesha ngangokunokwenzeka.

Yikuphi ukulungisa okuzosiza ukuqeda ikhodi? P0143?

Ukuxazulula inkinga nge-DTC P0143 ngokuvamile kuhilela izinyathelo ezilandelayo:

Ukushintshwa Kwenzwa Yomoya-mpilo: Uma inzwa yomoya-mpilo ihluleka noma inesici, kufanele kushintshwe entsha ehlangabezana nezicaciso zomkhiqizi wemoto.
Ukuhlola Izintambo Nokuxhumana: Yenza ukuhlola okuphelele kwezintambo kanye nokuxhumana okuhlotshaniswa nenzwa ye-oxygen. Qinisekisa ukuthi i-wiring ayilimele, izixhumi zixhumeke kahle futhi akukho ukugqwala.
Ukuhlola nokufaka amafuse esikhundleni: Hlola amafuse ahlinzeka ngomjikelezo wokuphakelwa kwamandla kwenzwa ye-oksijini. Zishintshe uma kunesidingo.
Ukuxilonga Ezinye Izingxenye: Hlola ezinye izingxenye zesistimu yokulawula injini ezifana ne-throttle body, intake multiple, uhlelo lomjovo kaphethiloli, nesiguquli se-catalytic ukuze ukhiphe izinkinga ezingaba khona ezithinta ukusebenza kwenzwa yomoya-mpilo.
Ukuvuselelwa Kwesofthiwe: Kwezinye izimo, ukubuyekeza isofthiwe ku-ECU kungase kusize ukuxazulula inkinga.

Uma ungaqiniseki ngamakhono akho okulungisa izimoto, kunconywa ukuthi uxhumane nomakhenikha ochwepheshe noma isitolo sokulungisa izimoto ukuze uhlole futhi ulungise inkinga.
