P0748 I-pressure control solenoid valve A kagesi

Ikhodi Yenkinga ye-OBD-II - P0748 - Ishidi Ledatha

I-P0748 - I-valve yokulawula ingcindezi ye-solenoid A, kagesi.

Le khodi imele i-Electric Pressure Control Solenoid. Le khodi ingase ibe nencazelo ehlukile kwezinye izinhlobo zezimoto, ngakho qiniseka ukuthi uhlola amakhodi athile emoto yakho.

Isho ukuthini ikhodi yenkinga P0748?

Le yi-Generic Transmission Diagnostic Trouble Code (DTC) futhi isetshenziswa kakhulu ezimotweni ze-OBD-II ezifakwe nge-automatic transmission.

Lokhu kungafaka, kodwa kungagcini lapho, iFord, Mercury, Lincoln, Jaguar, Chevrolet, Toyota, Nissan, Allison / Duramax, Dodge, Jeep, Honda, Acura, njll. unyaka. , yenza, imodeli kanye nemishini yeyunithi yamandla.

Lapho i-P0748 OBD-II DTC isethiwe, imojula yokulawula i-powertrain (PCM) ithole inkinga nge-solenoid yokulawula ingcindezi yokudlulisa i-solenoid "A". Iningi lemishini eshintshashintshayo inama-solenoid okungenani amathathu, okungama-solenoid A, B, kanye no-C. Amakhodi ezinkinga ahlotshaniswa ne-solenoid "A" angu-P0745, P0746, P0747, P0748, kanye ne-P0749. Isethi yekhodi isekelwe iphutha elithile elixwayisa i-PCM futhi likhanyise ukukhanya kwenjini yokuhlola.

Amandla okulawula ingcindezi yokudlulisa ilawula ingcindezi yoketshezi ukuze isebenze kahle ngokuhambisa okuzenzakalelayo. I-PCM ithola isignali ye-elekthronikhi esuselwa kwingcindezi engaphakathi kwama-solenoids. Ukudluliswa okuzenzakalelayo kulawulwa ngamabhande nokuxhuma okushintsha amagiya ngokufaka ingcindezi yoketshezi endaweni efanele ngesikhathi esifanele. Ngokuya ngamasignali avela kumadivayisi ahambisana nokulawulwa kwejubane lemoto, i-PCM ilawula ama-solenoids okucindezela ukuqondisa uketshezi ngokucindezela okufanele kumasekhethi ahlukahlukene wokubacindezela ashintsha isilinganiso sokudlulisa ngesikhathi esifanele.

I-P0748 isethwe yi-PCM lapho i-solenoid ka- "A" yokulawula ingcindezi ihlangabezana nephutha likagesi.

Isibonelo se-solenoid yokulawula ingcindezi yokudlulisa:

Buyini ubunzima bale DTC?

Ubukhali bale khodi imvamisa buqala ngokulingene, kepha bungadlulela ngokushesha buye ezingeni elibi kakhulu uma bungalungiswa ngesikhathi esifanele.

Yiziphi ezinye izimpawu zekhodi P0748?

Uma le khodi igcinwe, ungase ungaboni noma yiziphi izimpawu ezisobala, noma ungase ubone izinkinga ezinkulu zokushintsha, njengokungashintshi nhlobo. Injini ingase ime lapho ingenzi lutho, ukushintsha amagiya kungase kube nzima noma kushelele, futhi ukudluliselwa kungase kushise kakhulu. Ezinye izimpawu zihlanganisa ukonga kukaphethiloli okuncishisiwe kanye nesibani sesikhombi sokungasebenzi kahle (MIL) sivuliwe. Amanye amakhodi angasethwa, njengalawo ahlobene nesilinganiso segiya, ama-shift solenoid, noma isiliphu sokudlulisela.

Izimpawu zekhodi yenkinga ye-P0748 zingafaka:

• Imoto iya kwimodi ephuthumayo
• Izitroli zokuhambisa uma ushintsha amagiya
• Ukushisa ngokweqile kokudluliswa
• Ukudluliswa kunamathele egiyeni
• Ukwehla komnotho kaphethiloli
• Izimpawu ezinjenge-misfire
• Isibani se-Check Engine sivuliwe

Yiziphi ezinye zezimbangela ezivamile zekhodi?

I-valve yokulawula ukucindezela i-solenoid ingase yehluleke uma kukhona noma yiziphi izimo ezilandelayo:

• Uketshezi lokudlulisela olungcolile noma olungcolile
• Uketshezi olunomthamo omncane
• Ukuvinjwa kwe-hydraulic kumaphaseji oketshezi okudlulisela
• I-valve yokulawula ingcindezi kagesi embi
• Iphutha lokudluliswa kwemishini kwangaphakathi
• I-TCM enephutha (Transmission Control Module)
• I-PCM enamaphutha (kuyaqabukela)
• Iphutha le-solenoid yokulawula ingcindezi
• Uketshezi olungcolile noma olonakele
• Isihlungi sokudlulisa esingcolile noma esivimbekile
• Ipompo lokudlulisa elinamaphutha
• Iphutha lokuhambisa umzimba we-valve
• Amaphaseji wokubacindezela anomkhawulo
• Isixhumi esonakalisiwe noma esonakele
• Izintambo ezingalungile noma ezilimele
• I-PCM enamaphutha

Yiziphi ezinye zezinyathelo zokuxazulula inkinga nge-P0748?

Ngaphambi kokuqala inqubo yokuxazulula inkinga nganoma iyiphi inkinga, kufanele ubuyekeze i-Technical Service Bulletins (TSB) yemoto ethile ngonyaka, imodeli nokudluliswa. Kwezinye izimo, lokhu kungakongela isikhathi esiningi ngokuhamba kwesikhathi ngokukukhomba endaweni efanele. Kufanele futhi uhlole amarekhodi ezimoto ukubheka ukuthi isihlungi noketshezi kugcine nini ukushintshwa, uma kungenzeka.

Ukuhlola uketshezi nezintambo

Isinyathelo sokuqala ukuhlola izinga loketshezi futhi uhlole isimo soketshezi ukuthi alinawo yini ukungcola. Ngaphambi kokushintsha uketshezi, kufanele uhlole amarekhodi emoto ukuthola ukuthi isihlungi noketshezi kugcine nini ukushintshwa.

Lokhu kulandelwa ukuhlolwa okubukwayo okuningiliziwe ukuhlola isimo se-wiring ukuthi sinamaphutha asobala yini. Hlola izixhumi nokuxhuma ukuphepha, ukugqwala nokonakala kwezikhonkwane. Lokhu kufanele kufaka yonke intambo nezixhumi kuma-solenoids wokulawula ingcindezi yokudlulisa, iphampu yokudlulisa, ne-PCM. Iphampu lokudlulisa lingaqhutshwa ngogesi noma ngemishini, ngokuya ngokucushwa.

Izinyathelo ezithuthukile

Izinyathelo ezingezekile zihlala ziqondene nezimoto futhi zidinga ukuthi kwenziwe imishini efanelekile efanele ukwenziwa ngokunembile. Lezi zinqubo zidinga imultimeter yedijithali kanye nemibhalo eqondene nezobuchwepheshe eqondene nemoto. Kufanele uthole imiyalo ethile yokuxazulula inkinga yemoto yakho ngaphambi kokuqhubeka ngezinyathelo ezithuthukile. Izidingo zamandla kagesi zingahluka kakhulu kusuka kwimodeli yemoto ukuya emotweni. Izidingo zengcindezi ye-Fluid nazo zizohluka ngokuya ngokwakhiwa kokudlulisa nokucushwa.

Ukuhlolwa kokuqhubeka

Ngaphandle kokuthi kuchazwe ngenye indlela kudathasethi, ukufundwa kwentambo okujwayelekile nokufundwa kokuxhumeka kufanele kube ngama-0 ohms wokumelana. Ukuhlolwa kokuqhubeka kufanele njalo kwenziwe ngamandla wesifunda kunganqanyuliwe ukugwema ukujikeleza okufishane kwesekethe futhi kudale umonakalo omkhulu. Ukumelana noma ukungabikho okuqhubekayo kubonisa izintambo ezingalungile ezivulekile noma ezifushane futhi ezidinga ukulungiswa noma ukushintshwa.

Yiziphi izindlela ezijwayelekile zokulungisa le khodi?

• Kumiselela uketshezi nesihlungi
• Faka esikhundleni se-solenoid yokulawula ingcindezi enesici.
• Lungisa noma shintsha ipompo lokuhambisa elingalungile
• Lungisa noma shintsha umzimba we-valve wokuhambisa onamaphutha
• Ukudluliswa kokugeleza kwamaphaseji ahlanzekile
• Ukuhlanza izixhumi kusuka ku-corrosion
• Ukulungisa noma ukushintsha izintambo
• Ukukhanya noma ukufaka i-PCM esikhundleni

Okungahle kwenzeke ku-misdiagnosis kungafaka:

• Inkinga yokusebenza kabi kwezinjini
• Inkinga yepompo yokudlulisa
• Inkinga yokudlulisa yangaphakathi
• Inkinga yokudlulisa

Ngethemba ukuthi ulwazi olukulesi sihloko lusizile ukukukhomba endaweni efanele yokuxazulula inkinga yakho yokulawula ingcindezi ye-solenoid DTC. Le ndatshana yenzelwe ulwazi kuphela futhi imininingwane ethile yezobuchwepheshe kanye namabhulethini wensizakalo yemoto yakho kufanele kuhlale kuqala.

AMAPHUTHA AVAMILE LAPHO KUHLOLWA IKHODI P0748

Ngokuvamile lokhu kungasebenzi kahle kubizwa ngokuthi inkinga yomlilo ongalungile enjinini noma iphampu yomfutho ophezulu ibhekwa njengembangela. Izintambo nezinye izifunda ezihilelekile zinganakwa njengezimbangela ezingase zibe khona. Kubalulekile ukuqinisekisa ukuthi inqubo ephelele yokuxilonga iyenziwa.

IYIZINKANI IKHODI P0748?

Izinkinga zokudlulisela kufanele zihlale zilungiswa ngokushesha ngangokunokwenzeka. Ngisho noma inkinga ingakathuthuki kwaze kwaba seqophelweni lapho kwenzeke khona ukungaphumeleli komshini kwangaphakathi, ukuqala kwezimpawu kusho ukuthi kunenkinga engase ibe nkulu ngesikhathi esifushane kakhulu.

YIKUPHI UKULUNGISA ONGALUNGISA IKHODI P0748?

Ukulungiswa okungaba khona kwale khodi yephutha kufaka phakathi:

• Ukulungiswa kwamasekhethi okulawula ukucindezela njengezintambo nezixhumi
• I-Pressure Regulator Solenoid Replacement
• Ukushintsha isilawuli somfutho we-elekthronikhi
• Ukubuyiselwa noma ukushintshwa kwawo wonke ama-gearbox, okuhlanganisa nesiguquli se-torque.
• Ukuhlanza nokushintsha uketshezi lokudlulisela
• Ukushintsha kwe-TSM

IMIBONO ENGEZIWE MAYELANA NEKHODI P0748 CABANGA

Ukuhlola isimo samafutha okudlulisela kuyisinyathelo esibalulekile ekuxazululeni inkinga yokudlulisela. Uma uketshezi lubukeka noma lunukela ukushile, noma lunombala omnyama, ongacacile, imoto cishe impela ihamba nezinga eliphansi loketshezi. Lokhu kusho ukuthi umonakalo wangaphakathi oyinhlekelele kungenzeka ukuthi usuvele wenzekile.

Nakuba ezinye izingxenye zenqubo yokuxilonga zingenziwa ekhaya, njengokuhlola uketshezi lwe-B. Transmission (uma une-dipstick). Kungcono ukuthintana nochwepheshe abaqeqeshiwe ngokushesha ngangokunokwenzeka.
