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 felle feela ho, General Motors, Dodge, Jeep, Chevrolet, Chrysler, Ram, jj. Le ha e le tse akaretsang, mehato e nepahetseng ea ho lokisa e ka fapana ho latela selemo sa meetso, make, model le phetiso.

OBD-II DTC P3449 le likhoutu tse tsamaellanang P3450, P3451 le P3452 li amahanngoa le sekhahla sa ho koala / ho laola sekhahla sa silinda # 7.

Morero oa sekhahla sa taolo ea pompo ea silinda 7 ke ho fetola ts'ebetso ea silindara (mohlala V4 mofuta oa enjene ea V8) ho ntlafatsa moruo oa mafura nakong ea ts'ebetso ea boima ba motlakase joalo ka ho khanna tseleng e kholo. Mojule oa taolo ea enjene (ECM) o laola mekhoa ea enjene ea silindara ea 4 kapa 8, ho kenyeletsoa le ho koala li-valve tsa motlakase bakeng sa li-cylinders tse 'ne tsa enjene. Khoutu ena e bua ka silindara ea 7, 'me lisilindara tse ling tse tharo ts'ebetsong ena li khethoa ke phetolo ea enjene le tatellano ea ho thunya silindara. Nomoro ea `` silinda deactivation solenoid '' e le ngoe e kentsoe haufi kapa haufi le lesoba haufi le silindara sena, ho latela koloi le tlhophiso.

Ha ECM e lemoha motlakase o sa tloaelehang kapa khanyetso ho sekontiri sa taolo ea li-valve sa ho thibela / ho kenya, DTC P7 e tla seta mme lebone la enjene ea cheke le tla bonesa haufinyane, leseli la lits'ebeletso tsa enjene, kapa ka bobeli li ka bonesa. Maemong a mang, ECM e kanna ea tima cylinder # 3449 injector ho fihlela bothata bo lokisoa mme khoutu e hlakotsoe, e leng se ka hlahisang enjene e sa bonahaleng hantle.

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 P3449 a ka kenyelletsa:

• Enjene e kanna ea se sebetse hantle
• Keketseho ea tšebeliso ea mafura
• Ts'ebetso e mpe 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 P3449 a ka kenyelletsa:

• Haelloang silindara shutdown solenoid
• 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

Ka mor'a moo, fumana likarolo tsohle tse amanang le cylinder 7 inlet shut-off control valve 'me u shebe tšenyo e totobetseng ea' mele. Ho itšetlehile ka koloi e khethehileng, potoloho ena e ka kenyelletsa likarolo tse 'maloa, ho kenyelletsa le solenoid ea ho koala, li-switches, matšoao a phoso 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. Ts'ebetso ena e lokela ho kenyelletsa likhokahano tsohle tsa motlakase le likhokahano ho likarolo tsohle, ho kenyeletsoa le ECM. Sheba leqephe le khethehileng la data ea koloi ho hlahloba cylinder 7 shutoff / intake valve control circuit configuration le ho netefatsa karolo e 'ngoe le e' ngoe e kenyelletsoeng potolohong, e ka kenyelletsang fuse kapa fusible link.
