I-P0477 I-valve yokulawula ukucindezela kwegesi "A" iphansi

I-P0477 - I-OBD-II Ikhodi Yenkinga Incazelo Yobuchwepheshe

I-valve yokulawula ingcindezi yegesi ephumayo "A" iphansi

Isho ukuthini ikhodi yephutha P0477?

Inkinga engu-P0477 ihlobene nokulawulwa kwe-valve ye-exhaust pressure ephansi futhi ingenzeka ezimotweni ezihlukahlukene, okuhlanganisa i-Ford, i-Dodge, i-Mercedes, i-Nissan ne-VW. Le khodi ikhombisa i-voltage engalungile efundwa inzwa yokucindezela kwegesi ephumayo bese ithunyelwa kumojula yokulawula injini (PCM). Uma le voltage ingaphansi kokujwayelekile, i-PCM igcina ikhodi engu-P0477.

I-valve ye-backpressure exhaust ilawula i-exhaust backpressure, esiza ukwandisa ukushisa kwangaphakathi nokunciphisa isikhathi sokumisa isithwathwa somoya emazingeni okushisa aphansi azungezile. I-Engine Control Module (ECM) isebenzisa ulwazi mayelana ne-exhaust backpressure, izinga lokushisa lomoya odonsayo, izinga lokushisa likawoyela wenjini, nomthwalo wenjini ukulawula ivalvu. I-valve ilawulwa ngesekethe yokuphuma engu-12V ngaphakathi kwe-ECM.

Emazingeni okushisa aphansi kanye nezimo ezithile, i-valve ingase ihlale ivaliwe, okubangela ukushisa kwangaphakathi. Njengoba injini nowoyela kushisa, i-valve ilawula ukucindezelwa kwe-exhaust emuva. Ukuxazulula inkinga nge-P0477 kungase kudinge ukuhlola izintambo, i-valve, nezinye izingxenye zesistimu yokulawula igesi ephumayo.

Izizathu ezingenzeka

Le khodi yenkinga (P0477) ingenzeka ngenxa yezinkinga ezimbalwa ezingaba khona:

1. Ivalvu yokuhlola i-exhaust manifold inephutha.
2. Izintambo ezixhuma i-valve yokuhlola i-exhaust manifold ingavuleka noma ibe mfushane.
3. Izinkinga kusekethe yevalvu yesheke ye-exhaust eningi, njengokungaxhumeki kahle kukagesi.
4. Amandla anganele kumjikelezo wamandla phakathi kwe-solenoid yokulawula ukucindezela kwegesi ephumayo kanye ne-PCM (Powertrain Control Module).
5. Vula kumjikelezo wokuphakelwa kwamandla phakathi kwe-solenoid yokulawula igesi ephumayo kanye ne-PCM.
6. Kufushane ukuya phansi kumjikelezo wokuphakelwa kwamandla we-exhaust gas pressure control electromagnet.
7. I-exhaust gas control relay inephutha.
8. Mhlawumbe i-solenoid yokulawula i-exhaust engalungile noma i-PCM engalungile (yize lokhu kungenzeki).

Ukuze kuxazululwe le khodi yephutha, ukuxilonga kufanele kwenziwe, kuqale ngokubheka izintambo nokuxhunywa kukagesi, nokuqhubeka nokuhlola izingxenye zesistimu yokulawula igesi ephumayo njenge-valve yokuhlola ekhipha izinto eziningi, ama-solenoid, nama-relay. Isizathu esingenzeka kakhulu yiphutha kuzintambo noma izingxenye zikagesi zesistimu.

Yiziphi izimpawu zekhodi yephutha? P0477?

Izimpawu ezihlobene nekhodi ye-P0477 zingabandakanya:

1. I-Malfunction Indicator Light (MIL) noma ilambu elithi "Hlola Injini" liyakhanya.
2. Ukuntuleka kwamandla enjini adingekayo.
3. Ukulahleka kokusebenza kwenjini, okuhlanganisa nezinkinga zokudonsa okungenzeka.
4. Isikhathi esingeziwe sokufudumala senjini ebandayo.

Lezi zimpawu zingase zibonise izinkinga eziphansi zokucindezela ohlelweni lokulawula ukucindezela kokukhipha.

Indlela yokuxilonga ikhodi yephutha P0477?

Ukuze ulwe nekhodi yephutha engu-P0477, kunconywa ukuthi ulandele lezi zinyathelo:

1. Hlola futhi ulungise ipayipi lokucindezela emuva elivalekile.
2. Lungisa, hlanza noma buyisela inzwa yokucindezela kwe-backpressure exhaust.
3. Lungisa noma shintsha i-valve yokuhlola ingcindezi yegesi ephumayo.
4. Hlola futhi, uma kunesidingo, lungisa noma iyiphi intambo yokubopha izintambo ezifushanisiwe noma enqanyuliwe.
5. Hlola ukuxhumana kukagesi kusekethe yevalvu yomfutho wangemuva. Lungisa noma shintsha uma kunesidingo.
6. Shintshanisa i-solenoid ye-valve ephumayo esontekile emuva.
7. Lungisa noma shintsha izingxenye zikagesi ezilimele njengezintambo nezixhumi.
8. Uma zonke ezinye izinyathelo zihluleka, cabanga ukwakha kabusha i-PCM engalungile (imojula yokulawula injini), nakuba lokhu kungenakwenzeka.
9. Kuyafaneleka futhi ukuxilonga nokulungisa izinkinga ezihlobene namanye amakhodi wephutha ku-PCM angase ahlobane nesistimu yokucindezela emuva kokukhipha amandla.
10. Ngaphambi kokwenza lezi zinyathelo, kunconywa ukuthi ubuyekeze i-Technical Service Bulletin (TSB) yemoto yakho ethile ukuze uqinisekise ukuthi umkhiqizi wemoto akahlinzekanga nge-firmware ye-PCM noma ukuhlela kabusha ukuze kuxazululwe le nkinga.
11. Khumbula ukwenza izivivinyo usebenzisa ithuluzi lokuskena ukuze usule ama-DTC enkumbulweni futhi ubone ukuthi ingabe ikhodi ye-P0477 iyabuya yini ngemva kokulungiswa.

Amaphutha okuxilonga

Ukuxilongwa Okungekho Kweshubhu Lokucindezela Emuva Elivalekile: Ishubhu yokucindezela emuva evalekile noma evalekile ingaba imbangela evamile yekhodi ye-P0477, nokho, ngezinye izikhathi ingagejwa ngesikhathi sokuxilongwa kokuqala. Kuyadingeka ukunaka lesi sici futhi uhlole isimo se-tube ngesikhathi sokuhlolwa kokuqala kwesistimu.

Ibucayi kangakanani ikhodi yephutha? P0477?

Ikhodi yenkinga i-P0477, ehlotshaniswa nokulawulwa kwe-valve yokucindezela okuphansi, ingathinta ukusebenza kwenjini nokusebenza kahle, ikakhulukazi phakathi nokuqala okubandayo. Nokho, lokhu akukhona ukungasebenzi kahle okuzomisa injini ngokushesha noma kube yingozi kumshayeli. Kodwa-ke, uma ikhodi ye-P0477 iphikelela, kungase kubangele ukwanda kokusetshenziswa kukaphethiloli, ukuncipha kwamandla, kanye nesikhathi eside sokufudumala kwenjini. Kunconywa ukuxazulula le nkinga ngokushesha ngangokunokwenzeka ukuze ugweme izinkinga ezengeziwe futhi ugcine injini isebenza ngokujwayelekile.

Yikuphi ukulungisa okuzosiza ukuqeda ikhodi? P0477?

Ukuze uxazulule ikhodi ephansi ye-P0477 Exhaust Pressure Valve Regulation, yenza lokhu kulungisa okulandelayo:

1. Ukulungisa Nokulungisa Ishubhu Lokucindezela Emuva Elivalekile: Hlola ukuvaleka kwepayipi le-exhaust.
2. Ukulungisa, ukuhlanzwa nokushintshwa kwenzwa yokucindezela kwe-exhaust backpressure: Inzwa ye-EBP ingadinga ukuhlanzwa noma ukushintshwa.
3. Ukushintsha i-valve yokuhlola ingcindezi yegesi ephumayo: Uma i-valve ilimele noma ingasebenzi kahle, ingadinga ukushintshwa.
4. Ukulungisa i-harness yevalvu yokukhipha umoya emfushane noma enqanyuliwe: Hlola isimo sezintambo futhi uzilungise noma uzishintshe uma kunesidingo.
5. Ihlola uxhumo lukagesi kumjikelezo wevalvu ye-exhaust back pressure: Naka isimo sokuxhunywa kukagesi futhi ulungise noma ushintshe uma kunesidingo.
6. Ukushintsha i-solenoid ye-valve ye-valve ye-exhaust ekhubazekile: Uma ama-solenoids onakalisiwe, ashintshe.
7. Ukulungisa noma ukulungisa izingxenye zikagesi ezilimele njengezintambo nezixhumi: Hlola izintambo zokulimala futhi ulungise noma ushintshe izingxenye ezilimele.
8. Ukubuyisela i-PCM engalungile: Ezimweni ezingavamile, imojula yokulawula injini (PCM) ingase idinge ukulungiswa noma ukushintshwa.
9. Ukuxilonga nokuxazulula izinkinga ezihlobene namanye amakhodi ku-PCM ahlobene nesistimu yengcindezi yokubuyisela exhaust: Hlola amanye amakhodi ahlobene futhi uxazulule izinkinga uma ekhona.

Qiniseka ukuthi wenza ukuxilonga nokulungisa ngokusho kwezincomo zomkhiqizi wemoto futhi usebenzise imishini efanele. Kuphinde kunconywe ukuthi uxhumane nomakhenikha oqeqeshiwe noma isitolo sokulungisa izimoto ukuze uxilonga ngokunembile futhi uxazulule inkinga yekhodi ye-P0477.
