I-P0257 Iphampu yomjovo yokulawula imitha kaphethiloli, uhla B

I-P0257 - I-OBD-II Ikhodi Yenkinga Incazelo Yobuchwepheshe

Ibanga/ukusebenza kokulawula ukulinganisa uphethiloli kwephampu yomjovo B (ikhamera/irotha/umjovo)

Isho ukuthini ikhodi yenkinga P0257?

Ikhodi evamile yokudlulisa/yenkinga yenjini engu-P0257 isebenza ezimotweni eziningi zikadizili ezine-OBD-II, okuhlanganisa iFord, iChevy, i-GMC, iRam nezinye, futhi kwesinye isikhathi iMercedes Benz neVW. Nakuba kujwayelekile, izindlela zokulungisa zingahluka kuye ngokwenziwa, imodeli, nonyaka.

Isekhethi yokulawula ukulinganisa kwephampu yomjovo “B” ihlanganisa inzwa ye-fuel rail position (FRP) kanye ne-fuel quantity actuator. I-FRP inikeza isignali ku-PCM ukuze ilawule ukulethwa kukaphethiloli. I-P0257 iqaliswa uma isignali ye-FRP ingahambisani nokulindelwe yi-PCM, noma umzuzwana.

Ikhodi P0257 ingenzeka ngenxa yezinkinga zemishini noma zikagesi, njengezinkinga ngesekhethi yenzwa ye-EVAP noma ye-FRP. Khumbula ukubheka imanuwali yokulungisa imoto yakho ukuze uthole imininingwane.

Izizathu ezingenzeka

Ikhodi P0257 ingenzeka ngezizathu ezahlukahlukene, kufaka phakathi:

1. Isihlungi sikaphethiloli esingcolile noma esivalekile.
2. Izinkinga ngamasekhethi avuliwe noma amafushane.
3. Izixhumi zikagesi okungenzeka zivuliwe noma zibe mfushane.
4. Iphampu yamafutha engalungile.
5. Umshayeli we-activator control control ku-powertrain control module unephutha.

Ikhodi ye-P0257 ingase futhi ibangelwe izici ezihlukahlukene, okuhlanganisa okuvulekile noma okufushane kumjikelezo wesiginali kuya kunzwa ye-FRP, okufushane ukuya phansi kumjikelezo wesignali yenzwa ye-FRP, noma ukulahlekelwa amandla noma umhlabathi kunzwa ye-FRP. Kungenzeka futhi ukuthi inzwa ye-FRP ngokwayo inephutha, nakuba lokhu kuncane kakhulu, noma ukwehluleka okungavamile kwe-PCM.

Yiziphi izimpawu zekhodi yenkinga P0257?

Izimpawu zekhodi yenkinga ye-P0257 zingafaka:

1. Isibani senkomba esingasebenzi kahle (MIL) sivuliwe.
2. Ukunciphisa ukusebenza kahle kukaphethiloli.

Ngokuvamile, izimpawu ezihlobene nekhodi ye-P0257 zingase zibe zincane. Le khodi iphikelela futhi ukukhanya kwenjini yokuhlola kungase kukhanye. Kwezinye izimo, imoto ingase ingaqalisi noma kube nzima ukuyiqalisa, futhi ingase ikhiphe intuthu eyengeziwe ohlelweni lwe-exhaust. Injini ingase iqhume kabi futhi isebenze kabi, ikakhulukazi uma izama ukusheshisa.

Indlela yokuxilonga ikhodi yenkinga P0257?

Omakhenikha basebenzisa iskena se-OBD-II ukuze bathole ukuxilonga. Ixhuma kukhompuyutha yemoto futhi iqoqe idatha, okuhlanganisa namakhodi ephutha. Ukusetha kabusha ikhodi kungabonisa ukuthi izobuya yini ngemva kokuxilongwa.

Iphuzu elihle lokuqala njalo ukuhlola amanqampunqampu esevisi yezobuchwepheshe (TSBs) ukuze imoto yakho ifunde ngezinkinga ezaziwayo nezisombululo zazo. Okulandelayo, thola inzwa ye-FRP, evame ukutholakala empompini yomjovo kaphethiloli. Hlola isixhumi nezintambo zokulimala nokugqwala, hlanza futhi ugcobe amatheminali.

Uma unethuluzi lokuskena, sula amakhodi enkathazo futhi ubone ukuthi i-P0257 iyabuya yini. Uma kunjalo, kuzomele uhlole inzwa ye-FRP namasekhethi ahlobene. Hlola amandla nokubekwa phansi kwenzwa. Uma ikhodi ibuya, inzwa ye-FRP ingase idinge ukushintshwa. Xhumana nomhloli wezimoto oqeqeshiwe ukuze uthole usizo olwengeziwe kanye nokushintshwa okungenzeka kwe-PCM uma kudingeka.

Amaphutha okuxilonga

Kubalulekile ukukhumbula ukuthi lapho uxilonga amakhodi enkathazo afana ne-P0257, ukuqagela ngembangela akulungile ngaso sonke isikhathi. Inkolelo yokuthi inkinga inama-injector noma izijovo zeyunithi ingase ingalungile. Njengoba uphawule kahle, ngokuvamile imbangela eyinhloko inkinga ngesihlungi sikaphethiloli noma ezinye izakhi zesistimu yokunikezela uphethiloli.

Ukuze uhlonze ngokunembile futhi ulungise inkinga, kuhle ngaso sonke isikhathi ukuthi ihlolwe kusetshenziswa amathuluzi namasu ochwepheshe, futhi uxhumane noomakhenikha abaqeqeshiwe. Lokhu kuzokusiza ugweme izindleko ezingadingekile zokushintsha izinto ezingadingekile futhi ubuyisele imoto yakho esimweni sokusebenza ngokushesha.

Ibucayi kangakanani ikhodi yenkathazo P0257?

Sicela uqaphele ukuthi ukukhanya kwenjini yokuhlola okukhanyisiwe namakhodi ephutha afana ne-P0257 akufanele kushaywe indiva. Ngisho noma imoto ibonakala ijwayelekile ngokubukeka, izinkinga ezingathi sína zokusebenza zingase zenzeke, okuhlanganisa ubunzima bokuqalisa injini noma ukuziphatha okungavamile kwemoto. Izinguquko ezinjalo ekusebenzeni kwemoto zingathinta ukuphepha nokusebenza kwemoto.

Ubunzima benkinga buncike esimweni sayo. Uma imbangela kuyinkinga yemishini, ingaba yingozi kakhulu. Uma kwenzeka ukwehluleka kukagesi, nakuba kungabalulekile kangako, kusadingeka ukuxazulula ngokushesha inkinga njengoba i-PCM (imodyuli yokulawula injini) ingabanxephezela ngezinga elithile.

Ikuphi ukulungiswa okuzoxazulula ikhodi ye-P0257?

Nazi izinyathelo ezimbalwa omakhenikha abangazithatha ukuze baxazulule ikhodi ye-P0257 emotweni yakho:

1. Xhuma idivayisi yakho ye-OBD-II ukuze uhlole imoto yakho.
2. Setha kabusha ikhodi bese uhlola kabusha ukuze ubone ukuthi ikhodi ye-P0257 iyabuya yini.
3. Hlola uxhumo lukagesi ukugqwala noma ezinye izinkinga. Uma kunesidingo, lungisa noma ushintshe izingxenye ezilimele.
4. Cabangela ukushintsha isihlungi sikaphethiloli.
5. Cabangela ukushintsha iphampu yakho kaphethiloli.
6. Bheka ukufaka esikhundleni se-activator yokulawula uphethiloli kumojuli yokulawula ukudlulisa.
