See se bolela eng?

Ena ke Khoutu ea Mathata ea Generic Powertrain Diagnostic Trouble (DTC) e sebetsang ho likoloi tse ngata tsa OBD-II (1996 le tse ncha). Sena se ka kenyelletsa, empa ha se na moeli ho, likoloi tse tsoang Dodge, Peugeot, Jeep, Chevrolet, Chrysler, jj. Leha e le ka sebopeho sa kakaretso, mehato e nepahetseng ea ho lokisa e ka fapana ho latela selemo sa mohlala, sebopeho, sebopeho le enjene.

OBD-II DTC P3405 le likhoutu tse tsamaellanang P3406, P3407 le P3408 li amahanngoa le sekontiri sa taolo ea li-valve tsa ho qeta monono.

Morero oa potoloho ea taolo ea "valve" ea ho qeta monono ke ho etsa hore pompo e sebetse e le hore e ikamahanye le tšebetso ea silindara (mohlala, V1 enjene ea V4 enjene) ho ntlafatsa moruo oa mafura nakong ea khanya ea motlakase kapa tseleng e kholo. Mojule oa taolo ea enjene (ECM) o laola mefuta ea enjine ea 8- kapa 4-silindara ka ho tima li-cylinders tse 'ne tsa enjene. Ts'ebetso ena e fihlelleha ka ho bulela li-solenoids tsa nako ea li-valve tse fetolang li-valve le ho tima ha ho hlokahala. Khoutu ena e bua ka silindara ea 8, 'me lisilindara tse ling tse tharo ts'ebetsong ena li khethoa ke taolo ea enjene le tatellano ea ho thunya silindara. ECM e tla fokotsa silindara ho fihlela metsotso e 1 ka mokhoa oa V10 ebe e khutlela mokhoeng oa V4 motsotso o le mong. Valve bakeng sa nako e fapaneng ea li-valve ea silinda ea nomoro ea 8 e kentsoe kapa haufi le mefuta e mengata ea ho qeta moea haufi le silinda sena, ho latela sebopeho le koloi.

Ha ECM e fumana motlakase o sa tloaelehang kapa khanyetso ho potoloho ea taolo ea pompo ea silinda 1, DTC P3405 e tla beha mme leseli la enjene ea cheke, leseli la ts'ebeletso ea enjene, kapa ka bobeli li ka bonesa. Maemong a mang, ECM e kanna ea tima sejoe sa cylinder 1 ho fihlela bothata bo lokisoa mme khoutu e hlakotsoe, e leng se ka hlahisang enjene e sa bonahaleng hantle.

Li-solenoids tsa ho koala Moqomo

Boima ba DTC ee ke bofe?

Boima ba khoutu ena bo ka fapana haholo ho tloha ho bo itekanetseng ho ea ho matla ho latela matšoao a itseng a bothata. Lits'oants'o tse mpe tsa thipa li hloka tlhokomelo e potlakileng kaha li ka baka tšenyo e sa feleng ho likarolo tsa enjene ea kahare.

A mang a matšoao a khoutu ke afe?

Matšoao a khoutu ea mathata a P3405 a ka kenyelletsa:

• Keketseho ea tšebeliso ea mafura
• Ts'ebetso e mpe ea enjene
• Enjene ea enjene
• Leseli la enjene ea ts'ebeletso le tla bonesoa haufinyane
• Leseli la enjene ea ho hlahloba le laetse

A mang a mabaka a tloaelehileng a khoutu ke afe?

Mabaka a khoutu ena ea P3405 a ka kenyelletsa:

• Solenoid ea sistimi ea li-valve ea nako e fapaneng e fosahetse.
• Boemo ba oli ea enjene e tlase kapa khatello
• Karolo e fokolang ea oli
• Wiring e fosahetseng kapa e senyehileng
• Sehokelo se senyehileng, se senyehileng kapa se hlephileng
• ECM e nang le phoso

Ke mehato efe e meng ea ho rarolla bothata ba P3405?

Mohato oa pele oa ho rarolla bothata leha e le bofe ke ho lekola li-Bulletins tsa Ts'ebetso ea Tlhaho ea koloi ka selemo, mohlala le enjene. Sena se ka u bolokela nako le chelete hobane ha e le hantle ke tharollo e tsebahalang bothateng bo tsebahalang.

Mohato oa bobeli ke ho hlahloba boemo ba oli ea enjene le ho etsa bonnete ba hore e bolokiloe ho isa boemong bo nepahetseng. Ebe u fumana likarolo tsohle tse amanang le potoloho ea cylinder 1 exhaust valve 'me u shebe tšenyo e hlakileng ea' mele. Ho itšetlehile ka koloi e itseng, potoloho ena e ka kenyelletsa likarolo tse 'maloa, ho kenyelletsa le solenoid ea nako ea valve e feto-fetohang, li-switches, matšoao a ho se sebetse hantle, le mochine oa ho laola enjene. Etsa tlhahlobo e phethahetseng ea pono ho hlahloba mehala e amanang le eona bakeng sa mefokolo e totobetseng joalo ka mengoapo, makhopho, mehala e pepeneneng, kapa matšoao a cheleng. Ka mor'a moo, hlahloba lihokelo le likhokahano bakeng sa ts'ireletso, kutu le tšenyo ho likhokahano. Sheba leqephe la data e khethehileng ea koloi ho netefatsa tlhophiso le ho khetholla karolo e 'ngoe le e' ngoe e kenyellelitsoeng ho cylinder 1 exhaust valve control circuit.

Mehato e tsoetseng pele

Mehato ea tlatsetso e ba koloi e ikhethang 'me e hloka hore lisebelisoa tse tsoetseng pele tse loketseng li etsoe ka nepo. Ts'ebetso tsena li hloka litokomane tsa dijithale tsa multimeter le tse ikhethileng tsa koloi. Boemong bona, khatello ea oli e ka nolofatsa ts'ebetso ea ho rarolla mathata ho netefatsa thibelo ea phallo ea oli.

Teko ea Voltage

Mefuta ea litšupiso le mefuta e lumelletsoeng e ka fapana ho latela koloi e itseng le phetolo ea potoloho. Lintlha tse ikhethileng tsa tekheniki li tla kenyelletsa litafole tsa ho rarolla mathata le tatellano e nepahetseng ea mehato ho u thusa ho fumana tlhahlobo e nepahetseng.

Haeba ts'ebetso ena e fumana hore mohloli oa motlakase kapa mobu ha o eo, ho ka hlokahala hore ho etsoe teko ea ho tsoela pele ho netefatsa bots'epehi ba mehala, likhokelo le likarolo tse ling. Liteko tsa tsoelo-pele li lokela ho lula li etsoa ka motlakase o khaohantsoeng le potoloho, 'me ho bala ho tloaelehileng bakeng sa wiring le likhokelo ho lokela ho ba 0 ohms ea ho hanyetsa. Ho hanyetsa kapa ho se tsoele pele ho bonts'a phoso ea wiring e bulehileng, e khutsufalitsoeng kapa e senyehileng mme e hloka ho lokisoa kapa ho nkeloa sebaka.

Ke mekhoa efe e metle ea ho lokisa khoutu ee?

• Ho tlosa solenoid nako belofo nako
• Ho hloekisa likhokelo ho tsoa ts'enyehong
• Lokisa kapa u tlose mohala o fosahetseng
• Ho hloekisa litemana tsa oli tse koetsoeng
• Ho khanya kapa ho nkela ECM sebaka

Phoso e akaretsang

• Ho tlosa solenoid ea nako e fapaneng ea li-valve ka khatello e sa lekaneng ea oli kapa wiring e fosahetseng ho etsa hore ECM e behe khoutu ena.

Rea ts'epa hore tlhaiso-leseling e fumanehang sehloohong sena e u thusitse ho u supisa tsela e nepahetseng ea ho rarolla bothata ba potoloho ea taolo ea li-valve tsa ho qeta. Sengoloa sena se etselitsoe tlhaiso-leseling feela mme lintlha tse ikhethang tsa tlhaiso-leseling le lintlha tsa ts'ebeletso bakeng sa koloi ea hau li lokela ho lula li etelletsa pele.
