Inzwa ye-P0142 O3 1 Ibhange XNUMX Ukungasebenzi Kwesekethe

I-P0142 - I-OBD-II Ikhodi Yenkinga Incazelo Yobuchwepheshe

Ikhodi yenkinga P0142 ikhombisa ukungasebenzi kahle kwesekhi ye-oxygen sensor 3 (ibhange 1).

Isho ukuthini ikhodi yephutha P0142?

Ikhodi yenkinga engu-P0142 ibonisa izinkinga ngenzwa ye-heater oxygen (O₂), etholakala osebeni lokuqala lwenjini (ngokuvamile eseduze nekhanda le-cylinder) futhi yakhelwe ukukala okuqukethwe komoyampilo kwamagesi akhipha umoya. Le nzwa ine-heater eyakhelwe ngaphakathi esiza ukuthi ifinyelele izinga lokushisa ngokushesha futhi ithuthukise ukunemba kwayo. Ikhodi P0142 ikhombisa ukwehluleka ku-heater yenzwa ye-oxygen.

Izizathu ezingenzeka

Ezinye izimbangela zekhodi yenkinga ye-P0142:

• Isici sokushisisa senzwa ye-oxygen eyonakele noma ehlulekile.
• Izintambo noma izixhumi ezixhuma inzwa ye-oxygen kumojula yokulawula i-electronic (ECM) ziphukile noma zigqwalile.
• Kukhona ukungasebenzi kahle kumojula yokulawula i-elekthronikhi (ECM).
• Izinkinga nge-fuse noma i-relay enika amandla isifudumezi senzwa ye-oxygen.
• Ukufakwa okungalungile noma ukulimala kwenzwa ye-oxygen.
• Izinkinga ngesistimu kagesi yemoto, njenge-voltage yokuphakelwa kwamandla, indawo ephansi, noma omunye umsindo kagesi.

Yiziphi izimpawu zekhodi yephutha? P0142?

Izimpawu ezingenzeka ze-DTC P0142:

• Ukwenyuka kokusetshenziswa kukaphethiloli: Uma inzwa ye-oxygen ingasebenzi kahle, ingabangela ingxube engalungile kaphethiloli nomoya, engabangela ukusetshenziswa kwamafutha okwenyuka.
• Injini engazinzile: Ingxube kaphethiloli/yomoya engalungile ingase futhi ibangele injini ukuba isebenze kabi, ingasebenzi kahle, noma ibangele nokuba isivinini sokungenzi lutho sigxume.
• Ukukhishwa kwekhabhoni eyengeziwe: Inzwa ye-oxygen engasebenzi kahle ingaholela ekwandeni kokukhishwa kwezinto eziyingozi kumagesi aphumayo.
• Ukonakala kokusebenza kwenjini: Uma i-ECM ingena kumodi exegayo ngenxa yokungatholakali kolwazi oluvela kunzwa ye-oxygen, lokhu kungase kubangele ukuncipha kwamandla enjini nokunye ukungasebenzi kahle.
• Kuvela iphutha kuphaneli yezinsimbi: Kwezinye izimo, ukukhanya kwe-Check Engine noma amanye amalambu ayisixwayiso ahlobene nokukhishwa kungakhanya.

Indlela yokuxilonga ikhodi yephutha P0142?

Ukuze uhlole ikhodi yenkinga yenzwa ye-oxygen ye-P0142, landela lezi zinyathelo:

1. Hlola uxhumo nezintambo: Hlola isimo sokuxhuma nezintambo eziholela kunzwa ye-oxygen. Qinisekisa ukuthi azilimele futhi zivikeleke kahle.
2. Hlola ukumelana: Sebenzisa i-multimeter ukuze uhlole ukumelana nezintambo zenzwa ye-oxygen nezixhumi. Qiniseka ukuthi amanani okumelana angaphakathi kwebanga elijwayelekile njengoba licaciswe emibhalweni yezobuchwepheshe yokwenziwa nemodeli yemoto yakho ethile.
3. Hlola i-voltage yokuhlinzeka: Usebenzisa i-multimeter, hlola amandla kagesi kusixhumi senzwa ye-oxygen. Qiniseka ukuthi i-voltage ihlangabezana nezicaciso zomkhiqizi.
4. Hlola izintambo zesignali: Hlola izintambo zesiginali yenzwa ye-oxygen ukuthi azigqwalile, azinqamuki, noma omunye umonakalo. Shintsha izintambo ezilimele uma kudingeka.
5. Hlola isimo senzwa ye-oxygen: Uma zonke izinyathelo zangaphambilini zingaxazululi inkinga, inzwa ye-oxygen ingase ibe nephutha futhi idinga ukushintshwa. Lokhu ngokuvamile kuhilela ukususa inzwa nokuhlola ukumelana kwayo noma i-voltage usebenzisa i-multimeter.
6. Bheka i-ECM: Uma zonke ezinye izingxenye zihlola futhi zisebenza kahle, inkinga ingase ibe nge-Engine Control Module (ECM). Kulokhu, ukuxilonga okwengeziwe kuyodingeka, okwenziwa uchwepheshe oqeqeshiwe esebenzisa imishini ekhethekile.

Amaphutha okuxilonga

Lapho uxilonga i-DTC P0142, kungenzeka amaphutha alandelayo:

• Ukuchazwa okungalungile kwedatha: Iphutha lingase lenzeke ngenxa yokutolikwa okungalungile kwedatha etholwe kwinzwa ye-oxygen. Ukungaqondi kahle kwamanani we-voltage noma ukumelana kungaholela eziphethweni ezingalungile mayelana nesimo senzwa.
• Ukuhlonza imbangela okungalungile: Elinye iphutha elivamile ukukhomba ngokungalungile imbangela yenkinga. Abanye oomakhenikha bangase bacabange ngokushesha ukuthi inkinga inenzwa ye-oxygen ngokwayo ngaphandle kokuhlola ezinye izimbangela ezingenzeka, njengezintambo ezilimele noma izinkinga nge-ECM.
• Ukushoda kokuhlola izingxenye ezengeziwe: Kwesinye isikhathi oomakhenikha bangase beqe ukuhlola ezinye izingxenye zesistimu yokukhipha umoya, njengesiguquli se-catalytic noma isihlungi somoya, esingase futhi siqalise ikhodi yenkathazo ye-P0142.
• Ukusebenzisa imishini engalungile: Amanye amaphutha angase enzeka ngenxa yokusetshenziswa kwezinto ezingafanele noma iziqu ezinganele zikachwepheshe lapho enza ukuxilonga. Ukusebenzisa uhlobo olungalungile lwe-multimeter noma ukungaqondi ngokugcwele ukuthi uhlelo lusebenza kanjani kungaholela eziphethweni ezingalungile.

Ukuze uvimbele lawa maphutha, kubalulekile ukuqonda kahle uhlelo lokuphatha injini, uhumushe kahle idatha futhi wenze ukuxilonga okuphelele usebenzisa amathuluzi namasu afanele.

Ibucayi kangakanani ikhodi yephutha? P0142?

Ikhodi yenkinga P0142 ikhombisa izinkinga ngenzwa ye-oxygen. Nakuba le khodi ingeyona ebucayi kakhulu, isadinga ukunakwa nokulungiswa ngokucophelela. Inzwa ye-oxygen engasebenzi kahle ingaholela ekusebenzeni kabi kwenjini, ukwanda kokukhipha umoya, ngisho nokulahlekelwa amandla kanye nokwenyuka kokusetshenziswa kukaphethiloli. Kubalulekile ukubona ngokushesha futhi ulungise le nkinga ukuze ugweme izinkinga ezinkulu kakhulu esikhathini esizayo.

Yikuphi ukulungisa okuzosiza ukuqeda ikhodi? P0142?

Ukuze uxazulule i-DTC P0142, landela lezi zinyathelo:

1. Ihlola izintambo nezixhumi: Hlola izintambo nezixhumi ezixhuma inzwa ye-oxygen kumojula yokulawula injini (ECM). Qinisekisa ukuthi izintambo aziphukile noma azishi futhi zixhumeke ngokuphephile.
2. Isivivinyo sokumelana: Hlola ukumelana kumjikelezo wenzwa ye-oxygen. Kufanele ibe ngaphakathi kwezicaciso zomkhiqizi. Uma ukumelana kungenasidingo, inzwa ye-oxygen ingase ibe nephutha futhi idinga ukushintshwa.
3. Ukushintsha inzwa ye-oxygen: Uma inzwa ye-oxygen inephutha, kufanele ishintshwe kufakwe i-analogue entsha yoqobo noma yekhwalithi ephezulu.
4. Ihlola I-Engine Control Module (ECM): Ezimweni ezingavamile, inkinga ingase ibe ngemojula yokulawula injini ngokwayo. Uma ezinye izimbangela ziye zakhishwa, i-ECM ingadinga ukuxilongwa noma ukushintshwa.
5. Ukusula amaphutha kanye nokuxilonga kabusha: Ngemva kokuqedwa kokulungiswa, sula i-DTC ku-ECM usebenzisa isithwebuli sokuxilonga. Bese uphinde uhlole ukuze uqiniseke ukuthi inkinga ixazululiwe.

Uma ungenalo ulwazi lokwenza lo msebenzi, kutuswa ukuthi uxhumane nomakhenikha wezimoto oqeqeshiwe noma isitolo sokulungisa izimoto ukuze uxilongwe futhi ulungiswe.
