P0479 Exhaust gas control control valve circuit intermittent

I-P0479 - I-OBD-II Ikhodi Yenkinga Incazelo Yobuchwepheshe

Ikhodi yenkinga engu-P0479 ikhombisa ukuthi i-PCM ithole i-voltage enyakazayo kumjikelezo wevalvu wokulawula ukucindezela kwegesi.

Isho ukuthini ikhodi yephutha P0479?

Ikhodi yenkinga engu-P0479 ikhombisa i-voltage ephakathi nendawo kusekethe yevalvu yokulawula ukucindezela kwegesi. Le khodi ivamise ukuvela ezimotweni ezinezinjini zikadizili nezine-turbocharged ezigadwe umfutho wegesi ephumayo. Ezimotweni ezinezinjini zikadizili noma ezine-turbocharged, i-valve yokulawula ukucindezela kwegesi ephumayo inesibopho sokulawula ukucindezela kwegesi ephumayo. I-PCM ibala ngokuzenzakalelayo ukucindezela kwegesi ekhishwayo edingekayo ngokusekelwe kudatha etholwe ku-throttle position sensor, i-tachometer nezinye izinzwa ngendlela yokufundwa kwe-voltage. Uma i-PCM ithola ukuthi i-voltage ye-valve yokulawula ukucindezela kwegesi ephumayo ihamba kancane, i-P0479 izokwenzeka.

Izizathu ezingenzeka

Ezinye izizathu ezingenzeka zekhodi yenkinga ye-P0479:

• Ukungasebenzi kahle kwe-Exhaust Gas Pressure Control Valve: I-valve ingase yonakaliswe noma ibe nephutha, okubangela ukuba ukucindezela kwegesi yokukhipha kungalungiseki kahle.
• Izinkinga Zesifunda: Ukuvula, ukugqwala, noma omunye umonakalo kumjikelezo kagesi oxhuma i-valve yokulawula ukucindezela kwegesi ephumayo kumodule yokulawula injini (PCM) kungabangela ukufundwa okungalungile noma kungabikho isignali evela ku-valve.
• Izinkinga Zenzwa: Ukungasebenzi kahle kwenzwa ye-throttle position, i-tachometer, noma ezinye izinzwa i-PCM ezisebenzisayo ukubala ingcindezi yokukhipha umoya edingekayo nakho kungabangela i-P0479.
• Izinkinga Zesofthiwe ye-PCM: Isofthiwe ye-PCM engalungile noma engasebenzi ingabangela i-valve yokulawula ukucindezela kwegesi ephumayo ukuthi ingasebenzi kahle.

Yiziphi izimpawu zekhodi yephutha? P0479?

Izimpawu ze-DTC P0479 zingahluka kuye ngembangela ethile kanye nohlobo lwemoto:

• Ikhodi yephutha Yenjini Yokuhlola ivela kudeshibhodi yemoto.
• Ukuphelelwa amandla enjini noma ukusebenza okungazinzile.
• Ukuwohloka komnotho kaphethiloli.
• Izinkinga ngokusheshisa noma ukuphendula kancane ku-pedal yegesi.
• Imisindo engajwayelekile noma ukudlidliza okuvela enjinini.
• Ukwenyuka kokusetshenziswa kukaphethiloli.
• Iphunga elingavamile elivela ohlelweni lwe-exhaust.

Indlela yokuxilonga ikhodi yephutha P0479?

Ukuxilonga i-DTC P0479, izinyathelo ezilandelayo ziyanconywa:

1. Hlola ikhodi yephutha: Sebenzisa isithwebuli sokuxilonga ukuze ufunde ikhodi ye-P0479 nanoma imaphi amakhodi enkinga engeziwe okungenzeka avele. Rekhoda amakhodi amaphutha ukuze uthole ukuhlaziya okwengeziwe.
2. Ukuhlola okubonakalayo: Hlola i-valve yokulawula ukucindezela kwegesi ephumayo nakho konke ukuxhumana kukagesi ukuze uthole umonakalo obonakalayo, ukugqwala, noma izintambo eziphukile. Qiniseka ukuthi konke ukuxhumana kuvikelekile.
3. Ihlola uxhumo lukagesi: Hlola ukuxhunywa kukagesi kwevalvu yokulawula ukucindezela kwegesi ephumayo ukuze uthole ukuxhumana okuhle nokugqwala. Uma kunesidingo, hlanza izintambo futhi uxhume kabusha izintambo.
4. Ukuhlolwa kwe-valve yokulawula ukucindezela: Sebenzisa i-multimeter ukuhlola ukumelana ne-voltage ku-valve yokulawula ukucindezela kwegesi ephumayo. Qiniseka ukuthi ukumelana kuhlangabezana nezimfuneko zomkhiqizi.
5. Ihlola inzwa yokuma kwe-throttle: Hlola inzwa yokuma kwe-throttle ukuze isebenze kahle njengoba ingase ibangele i-voltage ephezulu noma ephansi kumjikelezo wevalvu yokulawula igesi ephumayo.
6. Ukuhlola okwengeziwe: Kuye ngesimo sakho esithile, ukuhlolwa okwengeziwe kwesistimu yokulawula injini nezinye izingxenye zesistimu yokukhipha umoya kungase kudingeke.
7. Ihlola izingxenye zemishini: Uma kunesidingo, hlola isimo sezingxenye zemishini yesistimu yokukhipha umoya, njenge-multifold exhaust, i-exhaust gas recirculation system kanye ne-turbocharging.

Ngemuva kokuhlonza nokuhlonza inkinga, kuyadingeka ukwenza ukulungiswa okufanele noma ukushintshwa kwezingxenye ezinephutha.

Amaphutha okuxilonga

Lapho uxilonga i-DTC P0479, kungenzeka amaphutha alandelayo:

• Yeqa ukuhlola okubonakalayo: Iphutha lingenzeka uma ukuhlolwa okubonakalayo ngokucophelela kwe-valve yokulawula ukucindezela kwegesi ephumayo kanye nokuxhumeka kwayo kagesi kungenziwanga. Ukweqa lesi sinyathelo kungase kuphumele emonakalweni ongatholakali noma ephukile izintambo.
• Ukuhlolwa kwengxenye okungalungile: Iphutha lenzeka uma ukuhlola kwenziwa ngethuluzi elingalungile noma indlela. Ukusebenzisa i-multimeter ngokungalungile noma ukungaqondi kahle uhlelo kungaholela eziphethweni ezingalungile.
• Ukuhlolwa okunganele kwenzwa yokuma kwe-throttle: Uma inzwa ye-throttle position ingahlolwanga ngokwanele, ingase ibangele izinkinga ze-voltage ezingatholakali kumjikelezo we-valve wokulawula ukucindezela kwegesi.
• Yeqa izivivinyo ezengeziwe: Ezinye izinkinga, njengezinkinga zesistimu yokulawula injini noma ukulimala komshini ohlelweni lokukhipha umoya, zingase ziphuthelwe ngesikhathi sokuxilongwa uma ukuhlolwa okwengeziwe nokuhlolwa kungenziwanga.
• Ukuchazwa kabi kwedatha: Iphutha lenzeka uma imiphumela yokuhlolwa ingachazwa kahle noma ishaywa indiva. Ukunaka okunganele emininingwaneni noma ukuchazwa okungalungile kwedatha kungaholela eziphethweni ezingalungile mayelana nezimbangela zokungasebenzi kahle.

Ukuze uthole ukuxilongwa okuphumelelayo, kufanele uqaphe ngokucophelela zonke izigaba zenqubo, usebenzise izindlela ezifanele namathuluzi, futhi wenze zonke izivivinyo ezidingekayo kanye nokuhlola ukuze uthole imbangela efanele yenkinga.

Ibucayi kangakanani ikhodi yephutha? P0479?

Ikhodi yenkinga P0479 ikhombisa inkinga ngevalvu yokulawula ingcindezi yegesi ephumayo, engathinta kabi ukusebenza kwenjini. Nakuba lokhu kungelona iphutha elibucayi, lisadinga ukunakwa ngokucophelela nokulungiswa ngokushesha.

Uma i-valve yokulawula ukucindezela kwegesi ephumayo ingasebenzi kahle, ingabangela isistimu ye-EGR ukuthi ingasebenzi kahle futhi ekugcineni yonakalise ukusebenza kwemoto kwemvelo. Ngaphezu kwalokho, kungase futhi kuholele ekwehleni kokusebenza kwenjini kanye nokwanda kokusetshenziswa kukaphethiloli.

Nakuba i-P0479 ingesona isimo esiphuthumayo, kunconywa ukuthi ilungiswe ngokushesha ngangokunokwenzeka ukuze kugwenywe izinkinga ezengeziwe futhi kugcinwe ukusebenza kwemoto okufanele.

Ikuphi ukulungiswa okuzoxazulula ikhodi ye-P0479?

Ukuze uxazulule i-DTC P0479, yenza lezi zinyathelo zokulungisa ezilandelayo:

1. Ihlola isekethe kagesi: Okokuqala, udinga ukuhlola umjikelezo kagesi oxhuma i-valve yokulawula ukucindezela kwegesi ephumayo kumojula yokulawula injini (PCM). Hlola ubuqotho bezintambo, abathintwayo nezixhumi ukuthi azigqwalile, alimale noma azinqamuki.
2. Ukuhlola i-valve yokulawula ukucindezela: Okulandelayo, kufanele uhlole i-valve yokulawula ingcindezi yegesi ephumayo ngokwayo ukuze isebenze kahle. Uma kunesidingo, i-valve kufanele ishintshwe.
3. Ukuxilongwa kusetshenziswa isithwebuli: Ukusetshenziswa kwesithwebuli sokuxilonga kuzokuvumela ukuthi uhlole ukusebenza kwe-valve futhi uthole noma yikuphi ukwehluleka noma ukungasebenzi kahle ekusebenzeni kwayo. Lokhu kuzokuvumela ukuthi unqume ngokunembile imbangela yekhodi ye-P0479.
4. Ukushintsha inzwa yokucindezela: Kwezinye izimo, imbangela yephutha ingase ibe ukungasebenzi kahle kwenzwa yokucindezela kwegesi yokukhipha. Uma lokhu kuqinisekiswa phakathi nenqubo yokuxilonga, le nzwa kufanele ishintshwe.
5. I-PCM firmware: Kwezinye izimo, ukubuyekeza isofthiwe yokulawula injini (PCM) kungasiza ukuxazulula inkinga yekhodi engu-P0479.
6. Ukuhlola amashubhu e-vacuum namapayipi: Hlola isimo samashubhu e-vacuum namapayipi axhuma i-valve yokulawula ukucindezela kwegesi ephumayo kwezinye izingxenye zesistimu. Qinisekisa ubuqotho bazo kanye nokungabi bikho kokuvuza.

Kunconywa ukuthi wenze lezi zinyathelo ngaphansi kokuqondisa kukakhenikha wezimoto onesipiliyoni noma uchwepheshe wesevisi yezimoto, ikakhulukazi uma ungenalo ulwazi oluningi ekulungiseni okuzenzakalelayo noma ukusebenza ngamasistimu kagesi.
