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 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 P3402 le likhoutu tse tsamaellanang P3401, P3403 le P3404 li amahanngoa le sekhahla sa ho koala / ho laola sekhahla sa silinda # 1.

Morero oa sekhahla sa taolo ea pompo ea silinda 1 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 1, '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 bothata ba tšebetso ka har'a voltage kapa ho hana ho potoloha ha silindara 1 ea ho noa / ho tima / ho laola, khoutu P3402 e tla seta mme lebone la enjene ea cheke, lebone la ts'ebeletso ea enjene, kapa ka bobeli li ka bonesa. Maemong a mang, ECM e kanna ea tima ente ea # 1 ho fihlela bothata bo lokisoa mme khoutu e hlakotsoe, e leng se ka hlahisang mollo o sa bonahaleng oa enjene.

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 P3402 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 P3402 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
• ECM e nang le phoso

Ke mehato efe e meng ea ho rarolla bothata ba P3402?

Mohato oa pele oa ho rarolla bothata bofe kapa bofe ke ho lekola likoloi tse ikhethileng tsa Technical Service Bulletins (TSBs) ka selemo, mohlala le enjene. Maemong a mang, sena se ka u bolokela nako e telele ka ho u supisa tsela e nepahetseng.

Mohato oa bobeli ke ho hlahloba boemo ba oli ea enjene le ho etsa bonnete ba hore e bolokiloe ho isa boemong bo nepahetseng. Ka mor'a moo, fumana likarolo tsohle tse amanang le cylinder 1 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 1 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.

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.

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?

• E nchafatsa ts'ebetso ea motlakase oa ho tima
• Ho hloekisa likhokelo ho tsoa ts'enyehong
• Lokisa kapa u tlose mohala o fosahetseng
• Phetoho ea oli le sefa
• Ho hloekisa litemana tsa oli tse koetsoeng
