I-P0048 Turbo / Supercharger Boost Control Circuit Ephakeme

I-P0048 Turbo / Supercharger Boost Control Circuit Ephakeme

Idatha ye-OBD-II DTC

Isekethe "A" yesilawuli sokuqinisa i-turbocharger / supercharger, isignali ephezulu

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezifakiwe ze-OBD-II ezine-supercharger noma i-turbocharger (iToyota, GMC Chevrolet Duramax, Mazda, Chrysler, Jeep, Ford Powerstroke, njll.).) . Noma kujwayelekile, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli.

Ama-Turbocharger nama-supercharger amaphampu omoya aphoqelela umoya enjinini ukuze kwandiswe amandla. Ama-supercharger ashayelwa ibhande ku-crankshaft yenjini, kanti ama-turbocharger ashayelwa amagesi e-exhaust enjini.

Izimoto eziningi zesimanje ezine-turbocharged zisebenzisa lokho okuthiwa yi-variable geometry turbocharger (VGT). Lolu hlobo lwe-turbocharger lunezinhlamvu ezilungiswayo ezungeze ingaphandle le-turbine elingavulwa futhi livaliwe ukushintsha inani lengcindezi yokuqinisa. Lokhu kuvumela ukuthi i-turbo ilawulwe ngaphandle kwesivinini senjini. Amaveni avamise ukuvula uma injini ingaphansi komthwalo omncane futhi ivuleke uma umthwalo wanda. Isikhundla se-blade silawulwa yi-powertrain control module (PCM), imvamisa isebenzisa i-elektroniki yokulawula i-solenoid noma imoto. Ukuma kwe-turbocharger kunqunywa kusetshenziswa inzwa yesikhundla esikhethekile.

Ezimotweni ezisebenzisa i-turbocharger noma i-supercharger yendabuko engaguquguquki yendabuko, umfutho ulawulwa nge-wastegate noma nge-wastegate. Le valve ivula ukukhipha umfutho wokunyusa. I-PCM iqaphe lolu hlelo ngenzwa yokunyusa umfutho.

Kule DTC, i- "A" ikhombisa inkinga engxenyeni yesekethe yohlelo hhayi uphawu oluthile noma into ethile.

Ikhodi P0048 isethwe lapho i-PCM inika isilawuli esiphezulu se-solenoid signal, noma ngabe injini isebenzisa i-VGT turbocharging noma i-turbocharger / supercharger yendabuko.

Uhlobo olulodwa lwe-turbocharger boost control solenoid valve:

I-Turbo / Supercharger Engine DTC ehlanganisiwe:

• I-P0045 Turbocharger / Supercharger Boost Control «A» Isekethe / Vula
• I-P0046 Turbocharger / Supercharger Boost Control "A" Ibanga Lesekethe / Ukusebenza
• P0047 Turbocharger / Supercharger Boost Control «A» Isekethe Phansi
• I-P0049 Turbocharger / Supercharger Turbine yeqiwe
• I-P004A Turbocharger / Supercharger Boost Control "A" Isifunda esingazinzile / esingazinzile

Ukuqina kwekhodi nezimpawu

Ukuqina kwalawa makhodi kumaphakathi kuya kokuqina. Kwezinye izimo, izinkinga ze-turbocharger/supercharger zingadala umonakalo omkhulu wenjini. Kunconywa ukuthi ulungise le khodi ngokushesha okukhulu.

Izimpawu zekhodi ye-P0048 zingafaka:

• Ukusheshisa ngokweqile okuholela ekuqhumeni nasekulimaleni kwenjini
• Hlola Injini Yokukhanya

izizathu

Izizathu ezingaba khona zokusetha le khodi:

• Inzwa yokuqinisa umfutho / iturbocharger engalungile
• Iphutha le-turbocharger / supercharger
• Iphutha le-solenoid yokulawula
• Izinkinga zokufaka izintambo
• I-PCM enamaphutha
• Ukuvuza komshini uma i-valve ilawulwa nge-vacuum

Izinqubo zokuxilonga nokulungisa

Qala ngokuhlola ngokubuka uhlelo lokulawula i-turbocharger ne-turbocharger. Bheka ukuxhumana okuxekethile, izintambo ezilimele, ukuvuza komshini, njll. Bese ubheka ama-bulletins ezinsizakalo zobuchwepheshe (i-TSB) maqondana nenkinga. Uma kungatholakali lutho, kuzodingeka uqhubekele ekuhlolweni kwesistimu ngezinyathelo.

Okulandelayo inqubo ejwayelekile njengoba ukuhlolwa kwale khodi kwehlukile emotweni kuya emotweni. Ukuze uvivinye ngokunembile isistimu, udinga ukubhekisa kutchartchch flowchart yomkhiqizi.

Qinisekisa ukusebenza kwesistimu ngokuyala i-solenoid yokulawula ukuthi ibeke kabusha ngethuluzi lokuskena elenzelwa eceleni. Nyusa isivinini senjini sifike cishe ku-1,200 XNUMX rpm bese ushintsha futhi ucishe i-solenoid. Lokhu kufanele kushintshe i-RPM yenjini nethuluzi lokuskena i-PID sensor position nayo kufanele ishintshe. Uma ijubane liyashintshashintsha, kepha isikhundla se-PID / isilawuli sengcindezi asiguquki, sola inkinga kunzwa noma kusekethe yayo. Uma i-RPM ingashintshi, sola ukuthi inkinga iku-solenoid yokulawula, i-turbocharger / supercharger, noma i-wiring.

• Ukuhlola isifunda: hlola amandla nomhlabathi ku-solenoid. Qaphela: Lapho wenza lezi zivivinyo, i-solenoid kumele i-ON VUWE ngethuluzi lokuskena. Uma kungekho ukuxhumana kwamandla noma komhlaba, uzodinga ukulandelela umdwebo wiring wefekthri ukuthola imbangela.
• Bheka i-turbocharger / supercharger: susa ukungena komoya ukuhlola i-turbocharger / supercharger ngomonakalo noma imfucumfucu. Uma kutholakala umonakalo, shintsha iyunithi.
• Bheka inzwa yokuma / yengcindezi kanye nesekethe: ezimweni eziningi izintambo ezintathu kufanele zixhunywe kunzwa yendawo: amandla, umhlabathi nesiginali. Qiniseka ukuthi bobathathu bakhona.
• Hlola i-solenoid yokulawula: Kwezinye izimo, ungabheka i-solenoid ngokuhlola ukumelana kwayo kwangaphakathi nge-ohmmeter. Bona Imininingwane Yokulungisa Imboni ngemininingwane. Ungaxhuma futhi i-solenoid emandleni nasemhlabathini ukuze uvivinye ukuthi kuyasebenza yini.
