I-P0139 - I-HO2S Bank 1 Inzwa 2 O1 Isekhethi yokuphendula enensayo (B2SXNUMX)

I-P0139 - incazelo yekhodi yenkinga

Inzwa ye-oksijini eshisayo engu-2 (ama-ho2), ezansi nomfula wesiguquli se-catalytic yezindlela ezintathu (eziningi), iqapha izinga le-oxygen kumagesi e-exhaust ebhange ngalinye lesilinda. Ukuze usebenze kahle we-catalyst, isilinganiso somoya kuphethiloli (i-air-fuel ratio) kufanele igcinwe iseduze ne-stoichiometric ratio efanelekile. I-voltage ephumayo yenzwa ye-ho2s ishintsha kungazelelwe eduze nesilinganiso se-stoichiometric.

Imojula yokulawula injini (ECM) ilungisa isikhathi somjovo kaphethiloli ukuze isilinganiso sikaphethiloli womoya sicishe sibe yi-stoichiometric. Ukuphendula ukuba khona komoyampilo kumagesi akhipha umoya, inzwa ye-ho2s ikhiqiza i-voltage engu-0,1 kuya ku-0,9 V. uma okuqukethwe kwe-oksijini yegesi yokukhipha ikhuphuka, isilinganiso se-air-fuel siba sincane.

Imojula ye-ECM ihumusha ingxube enciphile lapho i-voltage yenzwa ye-ho2s ingaphansi kuka-0,45V. uma okuqukethwe kwe-oxygen yamagesi okukhipha umoya kuncipha, isilinganiso se-air-fuel siba sicebile. Imojula ye-ECM ihumusha isignali ecebile lapho i-voltage yenzwa ye-ho2s idlula u-0,45V.

Isho ukuthini i-DTC P0139?

Ikhodi yenkinga engu-P0139 ihlotshaniswa nenzwa yomoya-mpilo esemuva yomshayeli futhi ikhombisa ukuthi isilinganiso se-air-fuel yenjini asilungiswa ngendlela efanele inzwa yomoya-mpilo noma isignali ye-ECM. Lokhu kungenzeka ngemva kokuba injini isifudumala noma uma injini ingasebenzi ngendlela evamile. “Ibhange 1” lisho ibhange lamasilinda aqukethe isilinda #1.

Ikhodi P0139 iyindinganiso evamile ye-OBD-II futhi ibonisa ukuthi inzwa ye-oxygen yasebhange engu-1, inzwa 1, ayizange ibonise ukwehla kwe-voltage engaphansi kuka-0,2 volts imizuzwana engu-7 ngesikhathi sokuvala uphethiloli. Lo mlayezo ubonisa impendulo yenzwa enensayo njengoba itholwe yi-Engine Control Module (ECM).

Izizathu ezingenzeka

Ngekhodi engu-P0139, i-ECM inciphisa ukunikezwa kukaphethiloli enjinini ngesikhathi sokuncipha kwenjini futhi zonke izinzwa ze-O2 kufanele ziphendule nge-voltage ephumayo engaphansi kuka-2 V, okubonisa okuqukethwe okuphezulu komoyampilo kumagesi okukhipha umoya. Ikhodi yephutha isethwe uma inzwa yasebhange engu-2 O1, inzwa 1, ingaphenduli ekunqanyulweni kukaphethiloli imizuzwana engu-7 noma ngaphezulu.

Lokhu kungase kubangelwe

• uphethiloli oweqile ekugelezeni kwegesi yokukhipha ngenxa yokuvuza okungenzeka ohlelweni lomjovo kaphethiloli,
• ukungasebenzi kahle kwenzwa ye-oksijeni eshisayo engemuva, block 1,
• Ibhange lenzwa ye-oxygen eshisayo engemuva 1 intambo yokubopha (ivuliwe noma imfushane),
• izinkinga ngoxhumo lukagesi lwebhethri ye-oksijini eshisayo engemuva 1,
• umfutho kaphethiloli onganele,
• ama-injection kaphethiloli angalungile,
• ukuvuza komoya ekuthatheni,
• amaphutha kuyunithi yenzwa ye-oxygen ene-reverse heat,
• Ibhange lenzwa ye-oxygen eshisayo engemuva 1 intambo yokubopha (ivuliwe noma imfushane),
• ukungasebenzi kahle kwesekethe 1 yenzwa ye-oksijeni eshisayo engemuva,
• umfutho kaphethiloli onganele,
• ama-injection kaphethiloli angalungile kanye nokungasebenzi kahle okungenzeka ekuvuzeni komoya,
• kanye nokuvuza kwegesi ephumayo.

Yiziphi izimpawu zekhodi ye-P0139?

• Injini ingase ime noma isebenze kabi ngenxa yobuningi bamafutha.
• Injini ingase ibonise ukungabaza ngesikhathi sokusheshisa ngemva kokwehla.
• Isibani senjini yokuhlola (noma isibani sokulungisa injini) siyakhanya.
• High petrol.
• Inani eliningi kakhulu lentuthu ohlelweni lwe-exhaust.

Indlela yokuxilonga ikhodi P0139?

1. Skena amakhodi namarekhodi edatha, uthwebule ulwazi kuhlaka.
2. Gada ukufundwa kwenzwa ye-O2 ukuze uthole ukuthi i-voltage yehla ngaphansi kuka-0,2 V ngesikhathi sokuncipha.
3. Hlola umfutho wamafutha enjini ukuze uthole ukuvuza ohlelweni lomjovo wesibaseli.
4. Qiniseka ukuthi inzwa ye-O2 ayingcolisiwe izinto zangaphandle ezifana nokupholisa noma uwoyela.
5. Hlola isistimu yokukhipha umoya ukuze uthole umonakalo noma izinkinga, ikakhulukazi endaweni yesiguquli se-catalytic.
6. Yenza izivivinyo ezinikezwe umenzi ukuze uthole ukuxilonga okwengeziwe.

Amaphutha okuxilonga

Ukuze ugweme ukuxilonga, landela lezi ziqondiso ezilula:

Uma zombili izinzwa (1 no-2) ohlangothini olulodwa lwenjini ziphuza ukuphendula, naka ukuvuza komjovo kaphethiloli okungenzeka kube khona ebhange lokuqala lenjini.

Ngaphambi kokuba le khodi yenzeke, xazulula izinkinga ezingaba khona nge-valve ebambekayo engase iphazamise inqubo yokuvala uphethiloli.

Hlola isimo sesiguquli se-catalytic ngomonakalo ongabangela inzwa ukuthi ingasebenzi kahle.

Ibucayi kangakanani ikhodi yenkathazo P0139?

Le khodi ikhombisa ukuthi noma ngabe inzwa iyinhle, injini isaqhubeka nokuletha uphethiloli ngesikhathi inciphisa, noma ingadingeki. Lokhu kungadala ukuthi kunyuke ukusetshenziswa kukaphethiloli ngisho injini ima uma imile uma kungena uphethiloli omningi emasimini.

I-ECM (imojula yokulawula injini) ayikwazi ukulawula ukucisha kukaphethiloli uma ama-injection kaphethiloli engavalwanga, okungase kubangele ukusetshenziswa kukaphethiloli ngokweqile.

Ikuphi ukulungisa okuzolungisa ikhodi ye-P0139?

Ukushintshwa kwenzwa ye-O2 yenzwa ye-1 yasebhange kufanele kwenziwe kuphela ngemva kokuba wonke amanye amasheke esistimu kaphethiloli ne-exhaust eseqediwe.

1. Okokuqala, hlola isimo sesistimu kaphethiloli bese ushintsha umjovo kaphethiloli ovuzayo uma utholakele.
2. Shintshanisa i-catalyst phambi kwenzwa uma inephutha.
3. Ngaphambi kokufaka inzwa ye-O2, hlanza ama-injection futhi uqiniseke ukuthi noma yikuphi ukuvuza kulungisiwe.

Ukusabela kwenzwa ehamba kancane ye-O2 kungase kube ngenxa yokuguga nokungcola. Njengoba inzwa ye-O2 ikala okuqukethwe komoyampilo kwamagesi akhipha umoya, noma yikuphi ukufakwa noma ukungcola okungaphezulu kwayo kungase kuphazamise ukulinganisa okulungile. Ezimweni ezinjalo, ukuhlanza noma ukufaka esikhundleni senzwa kungasiza ukubuyisela ukusebenza kwayo futhi kuthuthukise impendulo yayo ekushintsheni kwamagesi okukhipha umoya.
