Ikhodi yenkinga ye-P0175 OBD-II: Ukushiswa Kucebile Kakhulu (Ibhange 2)

Idatha ye-DTC P0175

I-P0175 - Ingxube inothe kakhulu (Ibhange 2)

Isho ukuthini ikhodi yenkinga P0175?

I-P0175 ikhombisa ukuthi imojula yokulawula injini (ECM) ithola uphethiloli omningi kanye ne-oxygen eyanele engxubeni yamafutha omoya (afr). Le khodi izosethwa lapho i-ECM ingakwazi ukunxephezela inani lomoya noma uphethiloli odingekayo ukuze kubuyiselwe isilinganiso sephethiloli yomoya kumapharamitha acacisiwe.

Ezinjini zikaphethiloli, isilinganiso sikaphethiloli esonga kakhulu singu-14,7:1, noma izingxenye zomoya eziyi-14,7 kuya kuphethiloli oyingxenye eyodwa. lesi silinganiso siphinde sidale inani eliphezulu lamandla ohlelweni lokuvutha.

Inqubo yomlilo ilula kakhulu kodwa ithambile. Izimoto eziningi zinamakamelo avuthayo amane kuya kwayisishiyagalombili ngaphakathi enjinini. umoya, uphethiloli, nenhlansi kuphoqeleka ukuthi kungene emagumbini avuthayo, okwenza "ukuqhuma" (okwaziwa kakhulu ngokuthi ukuvutha). inhlansi inikezwa ekamelweni ngalinye elivuthayo i-nanosecond eyodwa ngemva kokuba umoya nophethiloli kufinyelele ekamelweni futhi liwuthungele. igumbi ngalinye elivuthayo linepiston; I-piston ngayinye iqhutshwa amandla omlilo ngesivinini esikhulu nangezikhathi ezahlukene.

umehluko ngesikhathi sepiston ngayinye kunqunywa isilinganiso samafutha omoya kanye nesikhathi senjini. uma i-piston yehla, kufanele ibuyele phezulu ngenqubo yokuvutha elandelayo. i-piston kancane kancane ihlehla ihlehla isikhathi ngasinye lapho enye yamasilinda ithola inqubo yayo yokuvutha, njengoba wonke exhunywe emhlanganweni ojikelezayo owaziwa ngokuthi i-crankshaft. kucishe kufane nomphumela we-juggling; nganoma yisiphi isikhathi, i-piston eyodwa iya phezulu, enye iphezulu, futhi i-piston yesithathu iya phansi.

uma okuthile kule nqubo kwehluleka, izingxenye zangaphakathi zenjini zizosebenza kanzima futhi zisebenze ngokumelene nezinye, noma injini ingase ingaqali nhlobo. Endabeni yekhodi P0175, cishe kuzokhuphuka ibanga legesi ngoba i-ECM ithole ukuthi kusetshenziswa igesi eningi kakhulu.

Le khodi yokuxilonga (i-dtc) iyikhodi evamile yokudlulisela, okusho ukuthi isebenza ezimotweni ezihlome nge-obd-ii. Nakuba ngokuvamile, izinyathelo ezithile zokulungisa zingahluka kuye ngokwenziwa/imodeli. Lokhu kusho ukuthi inzwa ye-oxygen esebhange 2 ithole isimo esicebile (i-oxygen encane kakhulu ekukhishweni). ezinjinini ze-v6/v8/v10, ibhange 2 liwuhlangothi lwenjini olungenayo # 1 isilinda. inothi. Le khodi yenkathazo ifana kakhulu nekhodi ye-P0172, futhi empeleni, imoto yakho ingase ibonise womabili amakhodi ngesikhathi esisodwa.

Incazelo ye-P0175 Nissan

Ngokuzifundela, isilinganiso sangempela sengxube yengxube yomoya/yephethiloli singasondela kusilinganiso sethiyori esisuselwe empendulweni evela kuzinzwa zomoya-mpilo ezishisayo. I-Engine Control Module (ECM) ibala lesi sinxephezelo ukuze ilungise umehluko phakathi kwezilinganiso zengxube zangempela nezetiyori. Uma isinxephezelo siphezulu kakhulu, okubonisa isilinganiso esinganele sengxube, i-ECM ihumusha lokhu njengokungasebenzi kahle kwesistimu yomjovo kaphethiloli futhi yenze kusebenze Inkomba Yesikhombi Sokungasebenzi (MIL) ngemva kokudlulisa ukuqonda kokuxilonga ohambweni olubili.

Izimpawu ze-DTC P0175

Cishe ngeke uzibone izinkinga ezinkulu zokusingatha, kodwa izimpawu ezilandelayo zingase zenzeke:

• Ukwenyuka kokusetshenziswa kukaphethiloli.
• Ukuba khona kwe-soot noma idiphozithi emnyama ohlelweni lwe-exhaust.
• Hlola inkomba ethi "Hlola Injini" kuphaneli yezinsimbi.
• Kungase kube nephunga elinamandla lokukhipha.

Izinkinga ze-DTC P0175

Ikhodi ye-P0175 ingasho ukuthi umcimbi owodwa noma eminingi yenzekile:

• Inzwa ye-mass air flow (MAF) ingcolile noma inephutha, mhlawumbe ngenxa yokusetshenziswa kwezihlungi zomoya "ezigcotshiwe".
• Ukuvuza kwe-vacuum.
• Izinkinga ngomfutho noma ukunikezwa kukaphethiloli.
• Inzwa ye-oxygen yangaphambili eshisayo inephutha.
• Ukushisa okungalungile.
• Ama-injection kaphethiloli angalungile.
• Umjovo wesibaseli uvalekile, uvinjiwe noma uyavuza.
• Isilawuli sikaphethiloli sinephutha.
• Inzwa yokugeleza komoya engcolile noma enephutha.
• Inzwa yokushisa yesipholisi engaphelele.
• I-thermostat engalungile.
• I-ECM idinga ukuhlelwa kabusha.
• Inzwa ye-oxygen engcolile noma enephutha.
• Ukuvuza kwe-vacuum.
• Inkinga ngokutholakala kwamafutha.
• Umfutho kaphethiloli ongalungile.

Ungazixilonga kanjani

• Hlola umfutho wamafutha.
• Hlola ama-injection kaphethiloli ukuze uthole imikhawulo.
• Hlola i-pulse ye-fuel injector.
• Hlola imigqa kaphethiloli ukuze uthole amaphinifa nokuqhekeka.
• Hlola yonke imigqa yevacuum ukuze uthole imifantu noma umonakalo.
• Hlola izinzwa zomoya-mpilo.
• Sebenzisa ithuluzi lokuskena ukukala izinga lokushisa lenjini, bese uqhathanisa imiphumela nethemometha ye-infrared.

Amaphutha okuxilonga

Ingxenye ibhekwa njengengavumelekile ngaphandle kokuqinisekiswa ngokuhlolwa.

Ibucayi kangakanani ikhodi yenkathazo P0175?

Uhlelo olunothe kakhulu lunganciphisa impilo yesiguquli se-catalytic futhi lukhulise ukusetshenziswa kukaphethiloli, okungabiza kakhulu.

Isilinganiso somoya ocindezelwe okungalungile singaholela ekusebenzeni kwenjini esindayo kanye nokwanda kokukhishwa kwezinto eziyingozi.

Yikuphi ukulungiswa okuzoxazulula ikhodi yenkinga ye-P0175?

Izixazululo ezingaba khona zihlanganisa:

1. Hlola wonke amapayipi evacuum nawe-PCV bese uwashintsha uma kunesidingo.
2. Hlanza inzwa yokugeleza komoya omkhulu. Uma udinga usizo, bheka imanuwali yesevisi yakho ukuze uthole indawo ekuyo. Ukuhlanza, kunconywa ukusebenzisa i-electronic cleaner noma i-brake cleaner. Qiniseka ukuthi inzwa yome ngokuphelele ngaphambi kokuyibuyisela futhi.
3. Hlola ulayini kaphethiloli ngokuqhekeka, ukuvuza noma amaphini.
4. Hlola umfutho kaphethiloli kumzila kaphethiloli.
5. Hlola isimo futhi, uma kunesidingo, hlanza ama-injection kaphethiloli. Ungasebenzisa isicoci somshini wokujova uphethiloli noma uxhumane nochwepheshe ukuze uhlanze/ushintshe.
6. Hlola ukuvuza kwe-exhaust enhla kwenzwa ye-oxygen yokuqala (nakuba lokhu kuyimbangela engenakwenzeka yenkinga).
7. Faka esikhundleni imigqa yokufunxa ephukile noma ephukile.
8. Hlanza noma shintsha izinzwa zomoya-mpilo.
9. Hlanza noma shintsha inzwa yokugeleza komoya.
10. Hlela kabusha i-ECM (imojula yokulawula injini) uma kunesidingo.
11. Shintshanisa iphampu yamafutha.
12. Shintsha isihlungi sikaphethiloli.
13. Shintshanisa izintambo zikaphethiloli ezilimele noma eziphiniwe.
14. Shintshanisa ama-injection kaphethiloli angalungile.
15. Shintshanisa i-thermostat ebambekile.
16. Shintshanisa inzwa yezinga lokushisa epholile engalungile.

Uyilungisa Kanjani Ikhodi Yenjini ye-P0175 ngemizuzu emi-2 [Izindlela ezi-2 ze-DIY / $8.99 Kuphela]

Amazwana engeziwe

Hlola ukuthi isistimu yokupholisa yemoto yakho isebenza kahle yini. Ukusebenza okungavamile kwesistimu yokupholisa kungaphazamisa ukusebenza kwenjini. Lokhu kungenxa yokuthi i-ECM ishunwe ukuze isebenze kahle emazingeni okushisa aphezulu ngezinsuku ezibandayo, okusiza injini ukuthi ifudumale ngokushesha. Uma inzwa yezinga lokushisa elipholile inephutha noma i-thermostat ibambekile, imoto ingase ingafinyeleli izinga lokushisa elifunekayo, okuholela engxubeni ehlala inothe.
