P0079 B1 Exhaust Valve Control Solenoid Potoloho e tlase

Lethathamo la lintlha tsa OBD-II DTC

Boemo ba lets'oao le tlase ho potoloho ea belofo ea solenoid ea taolo ea valve ea ho qeta (Banka 1)

See se bolela eng?

Khoutu ena ke khoutu ea "powertrain" e tloaelehileng ea OBD-II, e bolelang hore e sebetsa mefuteng eohle ea likoloi le likoloi (1996 le tse ncha), leha mehato e ikhethileng ea ho lokisa e ka fapana ho latela mohlala.

Likoloing tse nang le sistimi ea li-valve ea nako e feto-fetohang (VVT), module ea taolo ea enjene / powertrain control module (ECM / PCM) e lekola boemo ba camshaft ka ho fetola boemo ba oli ea enjene le camshaft position control solenoid. Solenoid ea taolo e laoloa ke lets'oao la pulse wide modulated (PWM) le tsoang ho ECM / PCM. ECM / PCM e lekola lets'oao lena mme, haeba matla a motlakase a le ka tlase ho tlhaiso-leseling, e beha DTC ena mme e bonesa Lebone la Sesebelisoa sa Ts'ebetso (MIL).

Banka ea 1 e bua ka lehlakore la # 1 la cylinder ea enjene - etsa bonnete ba hore u hlahloba ho latela litlhaloso tsa moetsi. The exhaust valve control solenoid hangata e fumaneha ka lehlakoreng le nang le mokelikeli o mongata oa hlooho ea silinda. Khoutu ena e tšoana le likhoutu P0078 le P0080. Khoutu ena e kanna ea tsamaea le P0027.

Mehato ea ho tseba

Wiring Harness - Hakolla likhokahanyo tsa marapo ho PCM/ECM u sebelisa setšoantšo sa lithapo, fumana lithapo tsa + le - ho solenoid. Solenoid e ka khannoa ho tloha ka lehlakoreng la fatše kapa ho tloha lehlakoreng la matla, ho itšetlehile ka kopo. Sheba lits'oants'o tsa lithapo tsa fektheri ho fumana hore na motlakase o phalla joang potolohong. U sebelisa digital voltmeter (DVOM) e behiloeng sebakeng sa li-volts, hlahloba motlakase ho terata e ntle ea betri ea koloi le terata e fosahetseng terata ka 'ngoe ho ea ho solenoid ea taolo. Ho itšetlehile ka kopo, haeba solenoid e thehiloe ho chassis, hlahloba terata ea matla ho solenoid ea taolo ho PCM / ECM wiring harness, ha hoa lokela ho ba le motlakase o teng. Haeba motlakase o le teng, hlahloba sebaka se sekhutšoane ho ea fatše ka har'a mohala ho ea ho solenoid ea taolo ka ho khaola lihokelo ebe u khutlela ho solenoid.

Laola Solenoid - Sheba sebaka se sekhutšoane ho ea fatše ka solenoid ea taolo ka ho hokela lead e le 'ngoe ea DVOM sebakeng se tsebahalang se setle le se seng ho terminal ka 'ngoe ho solenoid ea taolo. Haeba khanyetso e le tlase, solenoid e ka khutsufatsoa ka hare.

PCM/ECM - Haeba lithapo tsohle le taolo ea solenoid li lokile, ho tla hlokahala ho beha leihlo solenoid ha enjene e ntse e sebetsa ka ho sheba lithapo ho PCM/ECM. U sebelisa sesebelisoa se tsoetseng pele sa skena se balang mesebetsi ea enjine, hlokomela potoloho ea mosebetsi e behiloeng ke taolo ea solenoid. Ho tla hlokahala ho laola solenoid ha enjene e ntse e sebetsa ka lebelo le meroalo e fapaneng. U sebelisa oscilloscope kapa graphical multimeter set to duty cycle, hokela terata e fosahetseng sebakeng se tsebahalang se setle le terata e ntle ho terminal efe kapa efe ea terata ho solenoid ka boeona. Ho bala ha multimeter ho lokela ho ts'oana le potoloho ea mosebetsi e boletsoeng sesebelisoa sa scan. Haeba li fapane, polarity e ka 'na ea fetoloa - kopanya mohala o motle ka lehlakoreng le leng la mohala ho solenoid' me u phete tlhahlobo ho hlahloba. Haeba ho se na pontšo e fumanoang ho PCM, PCM ka boeona e ka 'na ea e-ba phoso.
