I-P0259 - I-OBD-II Ikhodi Yenkinga Incazelo Yobuchwepheshe

Izinga eliphezulu lokulawula umthamo kaphethiloli wephampu yomjovo B

Isho ukuthini ikhodi yephutha P0259?

Ikhodi P0259 ikhombisa izinga eliphezulu lokulawula ukulinganisa uphethiloli wepompo lomjovo (ikhamera/irotha/umjovo). Lesi simo senzeka lapho i-voltage ku-sensor ihlala ngaphezu kwezinga elicacisiwe (imvamisa enkulu kuno-4,8 V) isikhathi eside. Lokhu ngokuvamile kungenxa yezinkinga kumjikelezo kagesi. Kubalulekile ukwenza ukuxilonga nokulungisa ukugwema ukuthikameza ukulethwa kukaphethiloli nokusebenza kwenjini.

Le khodi yokuxilonga i-P0259 isebenza ezinjinini ezahlukahlukene zikadizili ezifakwe uhlelo lwe-OBD-II. Ingenzeka kwaFord, Chevy, GMC, Ram, nakwezinye izinhlobo zeMercedes Benz kanye neVW. Kodwa-ke, izinqubo zokuxazulula inkinga zingahluka kuye ngokwakhiwa, imodeli, nokucushwa kwemoto.

Iphampu yomjovo "B" isistimu yokulawula ukulinganisa uphethiloli ngokuvamile ihlanganisa inzwa ye-fuel rack position (FRP) kanye nedrayivu yobuningi bamafutha. Inzwa ye-FRP iguqula inani likaphethiloli wedizili elinikezwe ama-injection libe isignali kagesi kumojula yokulawula i-powertrain (PCM). I-PCM isebenzisa lesi siginali ukuze inqume inani likaphethiloli elinikezwa injini ngokusekelwe ezimweni zamanje.

Ikhodi P0259 ikhombisa ukuthi isignali yokufaka inzwa ye-FRP ayifani nezimo ezijwayelekile zokusebenza kwenjini ezigcinwe kumemori ye-PCM. Le khodi iphinda ihlole isignali kagesi kusuka kunzwa ye-FRP uma ukhiye uvuliwe ekuqaleni.

Ukuze uxazulule izinkinga, bheka imanuwali yokulungisa yohlobo oluthile lwemoto yakho. Izinqubo zingahluka kuye ngomkhiqizi, uhlobo lwenzwa ye-FRP, nombala wentambo, futhi kuzodinga ukuxilongwa okuningiliziwe kanye nokungenzeka kulungiswe isekethe kagesi.

Izizathu ezingenzeka

Izimbangela zekhodi ye-P0259 zingabandakanya:

Isifunda esifushane kumjikelezo wesiginali yenzwa ye-FRP.
Ukuphelelwa amandla noma ukumiswa kwenzwa ye-FRP.
Ukuhluleka kwenzwa ye-FRP.
Ukwehluleka kwe-PCM okungenzeka (akunakwenzeka).
Isijojo sikaphethiloli esivuzayo noma esilimele.
Izinkinga ngepompo likaphethiloli.
Ukuvuza kwe-vacuum yenjini.
Ukungasebenzi kahle kwenzwa yomoya-mpilo.
Izinkinga ngokugeleza komoya omningi noma inzwa yokucindezela komoya ehlukahlukene.
Ukuxhumeka kukagesi okungalungile.
Ukuhluleka kwe-PCM.

Ukuthola kanye nokulungisa lezi zinkinga kudinga ukuxilonga futhi ngokunokwenzeka nokulungisa izingxenye zikagesi nemishini yemoto.

Yiziphi izimpawu zekhodi yephutha? P0259?

Izimpawu zekhodi yenkinga ye-P0259 zingabandakanya okulandelayo:

Izimpawu ezijwayelekile:

Amandla enjini aphansi nokusebenza okulinganiselwe.
Ukusabela kwe-throttle okungavamile kanye nokuqala kwamakhaza okunzima.
Ukunciphisa ukusebenza kahle kukaphethiloli.
Ukusebenza kwenjini enensayo nomsindo owandayo.
Ukungasebenzi kahle kwe-ECM/PCM.
Ukusebenzisa injini ngengxube ecebile noma ethambile.
Injini ayifihli kahle futhi ilahlekelwa ukusabela kwe-throttle.
Ukukhishwa kwentuthu enjinini ngesikhathi sokuqalisa ngekhabhoni eyandayo.

Izimpawu ezengeziwe:

Ukukhanya kwenkomba yokungasebenzi kahle (MIL) ukukhanya.
Ukwehliswa okwengeziwe ekusebenzeni kahle kukaphethiloli.

Indlela yokuxilonga ikhodi yephutha P0259?

Ukuze uhlole ngempumelelo ikhodi ye-P0259 futhi uxazulule izimbangela zayo, landela lezi zinyathelo:

Bheka amanqamu wezobuchwepheshe (TSB): Qala ngokuhlola amanqampunqampu esevisi yezobuchwepheshe ahlotshaniswa nemoto yakho. Kungenzeka ukuthi inkinga yakho isivele iyinkinga eyaziwayo nexazululiwe, futhi umenzi unikeze isisombululo esifanele, esingakongela isikhathi nemali lapho uxilonga.
Thola inzwa ye-FRP: Thola inzwa ye-fuel rail position (FRP) emotweni yakho. Le nzwa ivamise ukutholakala ngaphakathi noma eceleni kwephampu yomjovo kaphethiloli futhi iboshelwa enjinini.
Hlola isixhumi nezintambo: Hlola ngokucophelela isixhumi nezintambo ezihlotshaniswa nenzwa ye-FRP. Bheka imihuzuko, ama-scuffs, izintambo ezilimele, ukusha noma ipulasitiki encibilikisiwe.
Hlanza futhi usevise isixhumi: Uma ukuhlanza amatheminali kuyadingeka, sebenzisa isicoci esikhethekile sikagesi kanye nebhulashi lepulasitiki. Ngemva kwalokhu, sebenzisa amafutha kagesi ezindaweni zokuxhumana.
Hlola ngethuluzi lokuxilonga: Uma unethuluzi lokuskena, sula ama-DTC ekhanda futhi ubone ukuthi ikhodi ye-P0259 iyabuya yini. Uma lokhu kungenzeki, inkinga ingase ibe ngoxhumo.
Hlola inzwa ye-FRP kanye nesifunda sayo: Uma ukhiye uvaliwe, nqamula isixhumi sikagesi senzwa ye-FRP bese uhlola i-voltage. Xhuma intambo emnyama ye-voltmeter yedijithali kutheminali yaphansi yesixhumi nomthofu obomvu kutheminali yamandla. Vula ukhiye bese uhlola ukuthi ukufundwa kuyafana yini nabakhiqizi bezimoto (ngokuvamile i-12V noma i-5V). Uma kungenjalo, lungisa noma shintsha amandla noma izintambo zaphansi, noma i-PCM imbala.
Hlola ikhebuli yesignali: Hambisa umthofu we-voltmeter obomvu usuka kutheminali yamandla uye kutheminali yekhebula lesignali. I-voltmeter kufanele ifunde i-5V. Uma kungenjalo, lungisa ikhebuli yesignali noma shintsha i-PCM.
Hlola isistimu yamafutha: Hlola ithangi likaphethiloli, izintambo zikaphethiloli, nesihlungi sikaphethiloli ukuze sibone umonakalo noma ukungasebenzi kahle.
Hlola umfutho wamafutha: Thatha ukufundwa komfutho kaphethiloli okwenziwa ngesandla esitimeleni sikaphethiloli futhi ukuqhathanise nezicaciso zokukhiqiza. Sebenzisa isithwebuli sokuxilonga ukuze uqhathanise lokhu kufundwa nokufunda mathupha.
Hlola iphampu yamafutha nama-injector: Bheka ngokucophelela isimo somjovo kaphethiloli ukuthi awukona yini umonakalo noma ukuvuza, bese uwushintsha noma uwulungise uma kunesidingo. Ukuhlola ukusebenza komjovo, sebenzisa inkomba ye-Noid bese wenza ukuhlola komsindo.
Bheka i-PCM: Bheka amaphutha e-PCM (imojuli yokulawula injini). Nakuba bengekho

Amaphutha okuxilonga

Ukuze kuhlolwe ngempumelelo futhi kuxazululwe inkinga, le ndlela elandelayo kufanele ilandelwe:

Ukuxilongwa okuphelele: Kubalulekile ukwenza ukuhlaziya okuphelele kwenkinga, kuqedwe ukuthi kungenzeka kube nezimbangela ezifihliwe.
Izingxenye ezibalulekile okufanele zihlolwe: Kufanele kuqashelwe ngokukhethekile lezi zingxenye ezilandelayo:

Isihlungi samafutha: Hlola isimo sesihlungi, njengoba ukuvala kungaphazamisa ukulethwa kukaphethiloli.
Ukulawula umfutho wamafutha: Linganisa ukusebenza kwesilawuli sokucindezela, njengoba ukungasebenzi kwayo kungase kubangele iphutha.
Iphampu yesibaseli: Hlola isimo sephampu, njengoba amaphampu angalungile angase abangele inkinga.
Imigqa yamafutha: Bheka izintambo zikaphethiloli ukuthi azivuzi yini, okungase kubangele ikhodi engu-P0259.
I-Powertrain Control Module (PCM): Hlola ukungasebenzi kahle kwe-PCM, nakuba izimo ezinjalo zingavamile, zingathinta uhlelo lokulethwa kukaphethiloli futhi zibangele iphutha.
Izintambo namahhanisi: Hlola ngokucophelela isimo sezintambo zikagesi namahhanisi, njengoba izinkinga kuzo zingaba umthombo wephutha.

Ukuqaliswa okuqhubekayo kwazo zonke izigaba zokuxilonga kanye nokuhlolwa ngokucophelela kwengxenye ngayinye efakwe ohlwini kuzokuvumela ukuthi unqume ngokunembile imbangela yangempela yephutha futhi uqale ukuyiqeda.
