I-P1257 (I-Volkswagen, i-Audi, i-Skoda, isihlalo) I-Valve kumjikelezo wokupholisa injini - isifunda esivulekile

I-P1257 - I-OBD-II Ikhodi Yenkinga Incazelo Yobuchwepheshe

Ikhodi yenkinga engu-P1257 ikhombisa isekethe evulekile kusekethe ye-valve kusekethe yokupholisa injini ezimotweni zeVolkswagen, Audi, Skoda, kanye neSeat.

Isho ukuthini ikhodi yephutha P1257?

Ikhodi yenkinga P1257 ikhombisa inkinga ngevalvu kusekethe yokupholisa injini. Isekhethi epholile ngokuvamile isetshenziselwa ukulawula izinga lokushisa lenjini. I-valve kule sekhethi ingavuleka noma ivale kuye ngesidingo sokupholisa injini. Isekhethi evulekile kuvalvu isho ukuthi isiyingi sikagesi esixhuma i-valve kuyunithi yokulawula injini yephukile. Lokhu kungaholela ekusebenzeni okungalungile kwesistimu yokupholisa futhi, ngenxa yalokho, izinkinga ngokushisa kwenjini.

Izizathu ezingenzeka

Ezinye izizathu ezingenzeka zekhodi yenkinga ye-P1257:

• Izintambo eziphukile noma ezilimele: Izintambo ezixhuma i-valve yesekethe epholile kumojula yokulawula injini ingase yephuke noma yonakaliswe ngenxa yokugqwala, ukushisa ngokweqile noma ukulimala komshini.
• Iphutha levalvu: Ivalvu ngokwayo kusekhethi yokupholisa ingase ibe nephutha ngenxa yendlela ephukile noma ukunamathela, okuholela ekulungisweni kokugeleza kokupholisa okungafanele.
• Izinkinga ngeyunithi yokulawula injini (ECU): Ukungasebenzi kahle kweyunithi yokulawula injini enesibopho sokulawula ivalvu yesekethe epholile kungase kubangele ukuthi ivalvu ingasebenzi kahle.
• Izinkinga zesistimu kagesi: I-voltage ehlinzekwa kuvalvu yesekethe epholile ingase ingalungile ngenxa yezinkinga zesistimu kagesi yemoto, njengamafuse aphephethiwe noma ukushisa ngokweqile kwe-relay.
• Izinkinga ngenzwa yezinga lokushisa: Uma inzwa yezinga lokushisa elawula i-valve yesekethe epholile yehlulekile noma inikeza idatha engalungile, ingase futhi ibangele i-P1257.

Ukuze unqume ngokunembile imbangela, kuyadingeka ukuxilonga imoto usebenzisa imishini ekhethekile.

Yiziphi izimpawu zekhodi yephutha? P1257?

Izimpawu zekhodi yenkinga P1257 zingahluka ngokuya ngembangela ethile yekhodi yephutha nezimo zokusebenza zenjini, ezinye zezimpawu ezingaba yilezi:

• Ukwanda kwezinga lokushisa kwenjini: Uma ivelufa esesekethe yesipholile ingasebenzi kahle ngenxa yesekhethi evulekile noma ukungasebenzi kahle, kungabangela izinga lokushisa lenjini likhuphuke. Umshayeli angase aqaphele izinga lokushisa lenjini likhuphuka ngaphezu kokuvamile kuphaneli yensimbi.
• Ukwehliswa kokusebenza: Izinga lokushisa lenjini elingalungile lingabangela ukusebenza kabi kwenjini, okuholela ekulahlekelweni kwamandla, ukusebenza kanzima, noma ngisho nokungenzi lutho okuntantayo.
• Izinguquko ekusebenzeni kwesistimu yokupholisa: Kungase kube noshintsho ekusebenzeni kwesistimu yokupholisa, njengokupholisa kwenjini okunganele noma ukuvuza kwe-coolant ngenxa yokusebenza okungalungile kwe-valve kusekethe yokujikeleza.
• Ukwenyuka kokusetshenziswa kukaphethiloli: Izinga lokushisa lenjini elingalungile lingabuye liholele ekwenyukeni kokusetshenziswa kukaphethiloli ngenxa yokungasebenzi kahle kwenjini.
• Amaphutha avela kuphaneli yezinsimbi: Kwezinye izimo, imoto ingase ibonise amaphutha kuphaneli yezinsimbi ezihlobene nesistimu yokupholisa noma ukuphathwa kwenjini.

Uma ubona noma yiziphi izimpawu ezilandelayo, kutuswa ukuthi ube nokuxilonga umakhenikha okufanelekile futhi ulungise inkinga ehlotshaniswa ne-DTC P1257.

Indlela yokuxilonga ikhodi yephutha P1257?

Ukuze uhlole i-DTC P1257, landela lezi zinyathelo:

1. Ihlola Amakhodi Ephutha: Sebenzisa ithuluzi lokuskena kokuxilonga ukuze ufunde amakhodi amaphutha avela ku-ECU. Qinisekisa ukuthi ikhodi P1257 ikhona futhi ubhale amanye amakhodi amaphutha ahlobene uma ekhona.
2. Ukuhlolwa okubonakalayo kwe-wiring: Hlola izintambo ezixhuma i-valve yesekethe epholisayo kumojuli yokulawula injini ukuze uthole amakhefu, umonakalo noma ukugqwala.
3. Ihlola ukuxhumana nezixhumi: Qiniseka ukuthi zonke izixhumi zikagesi nezixhumi zisesimweni esihle futhi zixhumeke ngokuphephile.
4. Ihlola i-valve yesifunda: Hlola isimo se-valve yesekethe epholile ukuvaleka noma ukunamathela. Uma i-valve ingavuli noma ivaleke kahle, kungase kudingeke ukuthi ishintshwe.
5. Ihlola amasignali kanye ne-voltage: Sebenzisa i-multimeter ukuhlola amasignali kanye ne-voltage ku-wiring ye-valve nokuxhumeka ku-ECM.
6. Ukuxilongwa kweyunithi yokulawula injini (ECU): Yenza ukuxilongwa kuyunithi yokulawula injini ukuze uhlole ukusebenza kwayo kanye nokuba khona kwamaphutha ahlobene nokulawulwa kwe-valve yomjikelezo.
7. Ukuhlolwa kwenzwa yezinga lokushisa: Hlola ukusebenza kwenzwa yezinga lokushisa elawula ukusebenza kwevalvu yesekethe epholile.
8. Ihlola isistimu yokupholisa: Hlola isimo sesistimu yokupholisa, okuhlanganisa i-thermostat, irediyetha, nokuvuza kokupholisa.

Uma ungenalo ulwazi noma amakhono okuzihlolela ngokwakho, kutuswa ukuthi uxhumane nomakhenikha wezimoto ochwepheshe noma isikhungo sesevisi.

Amaphutha okuxilonga

Lapho uxilonga i-DTC P1257, kungenzeka amaphutha alandelayo:

• Ukuchazwa okungalungile kwekhodi yephutha: Kwesinye isikhathi oomakhenikha bangase bahumushe ngokungeyikho ikhodi ye-P1257 futhi baqale ukushintsha izingxenye ngaphandle kokwenza ukuxilonga okwanele. Lokhu kungase kubangele izindleko zokulungisa ezingadingekile.
• Ukuxilongwa okungaphelele: Ukungenzi ukuxilonga okuphelele kungase kuphumele ekuphutheni ezinye izinkinga ezingase zihlobane nezimpawu kodwa zingabonakali ngekhodi ye-P1257.
• Ukuhlolwa okunganele kwezintambo nokuxhumana: Ukwehluleka ukuhlola izintambo nokuxhumana kungase kubangele ukuthi imbangela yephutha ibonwe ngokungalungile. Kubalulekile ukuhlola ngokucophelela konke ukuxhumana kanye nezintambo zokunqamuka, ukulimala noma ukugqwala.
• Ukungasebenzi kahle kwenzwa yezinga lokushisa: Ukuhluleka ukucabangela ukuthi kungenzeka yini inzwa yezinga lokushisa engalungile kungase kubangele ukuxilongwa okungalungile kanye nokushintshwa kwezingxenye ezingadingekile.
• Ukuhlolwa kwevalvu yesiyingi kuhlulekile: Ukuhlolwa okungalungile kwe-valve yesifunda epholile noma ukunakwa okwanele ekusebenzeni kwayo kungase kuholele eziphethweni ezingalungile kanye nokulungiswa okuyiphutha.

Ukuze ugweme lawa maphutha, kubalulekile ukwenza ukuxilongwa okuphelele, kucatshangelwa zonke izimbangela ezingenzeka zekhodi ye-P1257.

Ibucayi kangakanani ikhodi yephutha? P1257?

Ikhodi yenkinga engu-P1257 kufanele ibhekwe njengento engathi sína njengoba ikhombisa izinkinga ezingaba khona ngesistimu yokupholisa injini. Ukwehluleka ukulawula izinga lokushisa kwenjini kungaholela emiphumeleni engathi sína njengokushisisa kwenjini, ukulimala kwezivalo, ngisho nokwehluleka kwenjini.

Amazinga okushisa enjini aphakeme angabangela ukupholisa okunganele, okuholela ekusebenzeni kabi kanye nokulimala kwenjini okungenzeka. Izimbangela zekhodi ye-P1257 zingahlukahluka, futhi uma inkinga ingaxazululwa, ingaholela emsebenzini wokulungisa onzima futhi obizayo.

Ngakho-ke, kunconywa ukuthi uxhumane nomakhenikha oqeqeshiwe ngokushesha ukuze uhlole futhi ulungise inkinga lapho uhlangabezana nekhodi yenkinga ye-P1257 ukuze ugweme ukulimala okukhulu kwenjini futhi uqinisekise ukusebenza kwemoto ephephile.

Yikuphi ukulungisa okuzosiza ukuqeda ikhodi? P1257?

Ukuxazulula ikhodi ye-P1257 kuzodinga izinyathelo ezithile zokulungisa ngokuya ngesizathu esithile sephutha, izenzo ezimbalwa zokulungisa okungenzeka:

1. Ukushintsha izintambo ezilimele noma izixhumi: Uma izintambo eziphukile noma ezilimele noma izixhumi zidala i-P1257, buyisela izintambo ezilimele noma izixhumi.
2. Ukushintsha i-valve yesifunda epholile: Uma i-valve kusekethe yokupholisa ingasebenzi kahle, faka i-valve entsha esikhundleni sayo.
3. Ukulungisa noma ukushintshwa kweyunithi yokulawula injini (ECU): Ezimweni ezingavamile, inkinga ingase ihlobane neyunithi yokulawula injini. Lungisa noma shintsha iyunithi yokulawula injini uma kutholakala amaphutha.
4. Ukuhlola nokulungisa uhlelo lokupholisa: Hlola isimo sesistimu yokupholisa, okuhlanganisa i-thermostat, irediyetha, nokuvuza kokupholisa. Lungisa noma shintsha noma yiziphi izinkinga ezikhonjiwe.
5. Ukuxilongwa nokulungiswa kwenzwa yezinga lokushisa: Hlola ukusebenza kwenzwa yezinga lokushisa elawula ukusebenza kwevalvu yesekethe epholile. Uma kunesidingo, shintsha noma lungisa inzwa.

Kubalulekile ukwenza ukuxilongwa okuphelele ukuze kutholakale imbangela yangempela yekhodi ye-P1257 ngaphambi kokwenza umsebenzi wokulungisa. Uma ungenalo ulwazi lokukhanda izimoto, kuhle ukuthinta umakhenikha oqeqeshiwe noma isikhungo sesevisi esigunyaziwe ukuze uxilongwe futhi ulungiswe.
