Ikhodi Yenkinga ye-P0159 OBD-II: Inzwa Yomoya-mpilo (Ibhange 2, Inzwa 2)

I-P0159 - incazelo yobuchwepheshe

Impendulo yenzwa yomoya-mpilo (O2) (ibhange 2, inzwa 2)

Isho ukuthini i-DTC P0159?

Ikhodi P0159 ikhodi yokudlulisela ekhombisa inkinga ngenzwa ethile ohlelweni lokukhipha umoya (ibhange 2, inzwa 2). Uma inzwa yomoya-mpilo ihamba kancane, kungase kube uphawu lokuthi inephutha. Le nzwa ethile inesibopho sokuqapha ukusebenza kahle kwe-catalyst kanye ne-emissions.

Le Khodi Yenkinga Yokuxilonga (i-DTC) ijwayelekile ekudluliselweni kwayo futhi isebenza ezimotweni ezinohlelo lwe-OBD-II. Naphezu kwemvelo evamile yekhodi, imininingwane yokulungisa ingase ihluke kuye ngokuthi yenziwe kanjani nemodeli yemoto. Sikhuluma ngenzwa ye-oxygen yangemuva ohlangothini lwesokudla lomgibeli. I-“Bank 2” ibhekisela ohlangothini lwenjini olungenayo isilinda #1. "Inzwa 2" iyinzwa yesibili ngemva kokushiya injini. Le khodi ibonisa ukuthi injini ayilawuli ingxube yomoya/yephethiloli njengoba kulindelwe i-ECM noma isignali yenzwa ye-oxygen. Lokhu kungenzeka kokubili ngenkathi injini ifudumala futhi ngesikhathi sokusebenza okuvamile.

Yiziphi izimpawu zekhodi yezinkinga P0159

Ungase ungaboni izinkinga ngokuphathwa kwemoto yakho, nakuba ezinye izimpawu zingase zibe khona.

Hlola Ukukhanya Kwenjini: Umsebenzi oyinhloko walokhu kukhanya ukukala ukukhishwa kwekhabhoni futhi awunawo umthelela obalulekile ekusebenzeni kwemoto.

Le nzwa iyinzwa ye-oxygen engezansi, okusho ukuthi itholakala ngemva kwesiguquli se-catalytic. Ikhompuyutha isebenzisa izinzwa zomoya-mpilo eziphansi ukuze ihlole ukusebenza kwe-catalyst nezinzwa eziphezulu ukuze ibale ingxube ye-fuel-air.

Izinkinga zekhodi P0159

Ikhodi ye-P0159 ingase ibonise okukodwa noma ngaphezulu kokulandelayo:

1. Inzwa yomoya-mpilo inephutha.
2. Ukulimala noma ukushwabana kwezintambo zenzwa.
3. Ukuba khona kokuvuza kwegesi ephumayo.

Le khodi isetha uma ngabe inzwa ye-oxygen ishintsha kancane. Kufanele inyakaze phakathi kuka-800 mV no-250 mV imijikelezo engu-16 ngaphezu kwamasekhondi angu-20. Uma inzwa ingahlangabezani naleli zinga, ithathwa njengenephutha. Lokhu ngokuvamile kungenxa yobudala noma ukungcoliswa kwenzwa.

Ukuvuza kwe-exhaust nakho kungabangela le khodi. Naphezu kwenkolelo evamile, ukuvuza kwe-exhaust kudonsa umoya-mpilo futhi kunciphise ukugeleza kwe-exhaust, okungachazwa yikhompyutha njengenzwa ye-oxygen enephutha.

Inzwa inezintambo ezine namasekhethi amabili. Uma enye yale mijikelezo imfushane noma inokumelana okuphezulu, ingase futhi ibangele ukuthi le khodi isethwe njengoba izimo ezinjalo zingathinta ukusebenza kwenzwa ye-oxygen.

Indlela yokuxilonga ikhodi P0159?

I-Technical Service Bulletins (TSBs) ikufanele uhlole izinkinga ezithile ezihlobene nokwakhiwa kanye nonyaka oyimodeli yemoto yakho.

Le khodi isethwa ikhompuyutha ngemva kokwenza izivivinyo ezithile. Ngakho-ke, uchwepheshe ohlonze imoto futhi wathola le khodi uzohlola ukuvuza kwe-exhaust ngaphambi kokufaka inzwa eshiwo (Ibhange 2, Inzwa 2).

Uma ukuhlolwa okunemininingwane eminingi kuyadingeka, kunezindlela ezimbalwa zokukwenza. Uchwepheshe angafinyelela ngokuqondile kumjikelezo wenzwa ye-oxygen futhi abheke ukusebenza kwawo esebenzisa i-oscilloscope. Lokhu ngokuvamile kwenziwa ngenkathi yethulwa i-propane ekuthatheni noma kwakhiwa ukuvuza kwe-vacuum ukuze kuqashwe impendulo yenzwa yomoya-mpilo ezimweni eziguqukayo. Lezi zivivinyo zivame ukuhlanganiswa ne-test drive.

Ukuhlolwa kokumelana kungenziwa ngokunqamula isixhumi senzwa ye-oxygen kusukela kuzintambo zemoto. Lokhu ngezinye izikhathi kwenziwa ngokushisisa inzwa ukuze ilingise izimo ezohlangabezana nazo lapho ifakwe kusistimu yokukhipha umoya.

Amaphutha okuxilonga

Ukwehluleka ukuhlonza ezinye izinkinga ezinjengokuvuza kwe-exhaust, ukuvuza kwevacuum noma imililo engalungile akuvamile. Ngezinye izikhathi ezinye izinkinga zingase zinganakwa futhi zingagejwa kalula.

Izinzwa zomoya-mpilo ezansi (izinzwa zomoya-mpilo ngemva kwesiguquli se-catalytic) ziklanyelwe ukusiza ukuqinisekisa ukuthi imoto yakho ihlangabezana nezindinganiso ze-EPA zokukhipha umoya. Le nzwa ye-oxygen ayiqapheli kuphela ukusebenza kahle kwe-catalyst, kodwa futhi yenza izivivinyo ukuze iqinisekise ukusebenza kwayo.

Imvelo eqinile yalezi zivivinyo idinga ukuthi zonke ezinye izinhlelo zisebenze ngendlela efanele noma imiphumela ingase inganembile. Ngakho-ke, ukususa iningi lamakhodi nezimpawu kufanele kucatshangelwe kuqala.

Ibucayi kangakanani ikhodi yenkathazo P0159?

Le khodi inomthelela omncane ekushayeleni kwansuku zonke. Lena akuyona inkinga engadinga ukushayela iloli elidonsayo.

Ukwethulwa kwalezi zinhlelo kwabangelwa inkinga enkulu yokufudumala kwembulunga yonke futhi kwenziwa yi-Environmental Protection Agency ngokubambisana nemboni yezimoto.

Ikuphi ukulungisa okuzolungisa ikhodi yenkinga ye-P0159?

Isinyathelo esilula ukusetha kabusha ikhodi futhi uhlole ukuthi iyabuya yini.

Uma ikhodi ibuya, inkinga kungenzeka ngenzwa yomoya-mpilo esemuva yohlangothi lomgibeli. Ungase udinge ukuyishintsha, kodwa futhi ucabangele lezi zixazululo ezilandelayo:

1. Hlola futhi ulungise noma yikuphi ukuvuza kwe-exhaust.
2. Hlola izintambo ngezinkinga (amasekhethi amafushane, izintambo eziphukile).
3. Hlola imvamisa kanye nobukhulu besiginali yenzwa ye-oxygen (uyazikhethela).
4. Hlola isimo senzwa ye-oxygen; uma igugile noma ingcolile, yishintshe.
5. Hlola ukuvuza komoya endaweni oyithathayo.
6. Hlola ukusebenza kwenzwa enkulu yokugeleza komoya.

Isixazululo esivame kakhulu kungaba ukufaka esikhundleni senzwa ye-oxygen eshiwo (ibhange 2, inzwa 2).

Lungisa ukuvuza kwe-exhaust ngaphambi kokufaka inzwa ye-oxygen.

Izintambo ezilimele kumjikelezo wenzwa ye-oxygen zingatholwa futhi kufanele zilungiswe. Lezi zintambo ngokuvamile zivikelekile futhi zidinga ukunakekelwa okukhethekile lapho zixhuma.

Uyilungisa Kanjani Ikhodi Yenjini ye-P0159 ngemizuzu emi-3 [Izindlela ezi-2 ze-DIY / $8.34 Kuphela]

Amazwana engeziwe mayelana nekhodi yephutha P0159

I-Bank 1 iyisethi yamasilinda aqukethe inombolo yesilinda.

I-Bank 2 iyiqembu lamasilinda angafaki inombolo yesilinda eyodwa.

Inzwa 1 iyinzwa ephambi kwesiguquli se-catalytic esisetshenziswa ikhompuyutha ukubala isilinganiso sikaphethiloli.

Inzwa yesi-2 iyinzwa etholakala ngemva kwesiguquli se-catalytic futhi isetshenziswa ngokuyinhloko ukuqapha ukukhishwa kwekhabhoni.

Ukuze imoto ihlole ukusebenza kwenzwa 2, kufanele kuhlangatshezwane nemibandela elandelayo. Le ndlela yokuthola amaphutha ingase yehluke phakathi kwabakhiqizi futhi isebenza ngaphansi kwezimo ezilandelayo:

1. Imoto ihamba ngesivinini esiphakathi kwamamayela angu-20 kuya kwangu-55 ngehora.
2. I-throttle ivuliwe okungenani imizuzwana engu-120.
3. Izinga lokushisa lokusebenza lidlula 70℃(158℉).
4. Izinga lokushisa le-catalytic converter lidlula u-600℃ (1112℉).
5. Isistimu yokuhwamuka kwe-emission ivaliwe.
6. Ikhodi isethiwe uma i-voltage yenzwa ye-oxygen ishintsha izikhathi ezingaphansi kwezingu-16 ukusuka kokucebile ukuya kokuncika ngesikhawu samasekhondi angu-20.

Lokhu kuhlola kusebenzisa izigaba ezimbili zokutholwa kwamaphutha.
