P0402 Phallo e Feteletseng ea Khase e Khetholloang

P0402 - Tlhaloso ea Setsebi

Phallo e feteletseng ea exhaust gas recirculation (EGR) e fumanwe.

P0402 ke khoutu e tloaelehileng ea OBD-II e fumanoeng ke mojule oa taolo ea enjene (ECM) e bonts'ang hore valve ea exhaust gas recirculation (EGR) e lumella khase e ngata haholo ea ho tsoa ha e laeloa ho bula phallo ea khase e kenang ka bongata.

Khoutu ea mathata P0402 e bolela'ng?

Khoutu ena ea Mathata a Tlhatlhobo (DTC) ke khoutu ea phetisetso e akaretsang, ho bolelang hore e sebetsa ho likoloi tse nang le thepa ea OBD-II. Le ha e le ka kakaretso, mehato e ikhethileng ea ho lokisa e ka fapana ho latela mofuta / mofuta.

EGR e emetse Exhaust Gas Recirculation. Ke karolo ea sistimi ea ho qeta koloi mme e sebelisetsoa ho fokotsa mocheso le khatello ea mollo ho laola li-oxide tsa naetrojene.

Ka tloaelo, sistimi ea motlakase oa ho qeta moea e na le likarolo tse tharo: sephahla sa khase se kenang, se sebelisang motlakase le phapang ea khatello ea khatello (DPF). Lintho tsena li sebetsa 'moho ho fana ka palo e nepahetseng ea ho pheta-pheta ho ipapisitse le mocheso oa enjene, mojaro, jj. Khoutu ea P0402 e bolela hore OBD e fumane palo e fetelletseng ea EGR.

Matšoao

U ka hlokomela mathata ka ho sebetsana, mohlala, enjene e kanna ea senyeha ha e sebetsa. Ho kanna ha ba le matšoao a mang hape.

• Leseli la Check Engine le tla tla 'me khoutu e tla bolokoa ho ECM.
• Enjene e ka 'na ea sebetsa hampe haeba valve e khomaretsoe sebakeng se bulehileng.
• Sistimi ea EGR ea enjine e kanna ea ba le ho lutla ha metsi ho sensor ea backpressure.

Lisosa tsa khoutu ea P0402

Khoutu ea P0402 e kanna ea bolela hore ketsahalo e le 'ngoe kapa tse' maloa tse latelang li etsahetse:

• Sensor ea DPFE (Differential Pressure) e na le sekoli mme e hloka ho nkeloa sebaka.
• Mokelikeli o felisang moea o koahetsoeng (ho ka etsahala hore o aha khabone).
• Ho qeta monono phepelo ea khase e fosahetse
• Sephahla sa motlakase oa khase se ka 'na sa se bulehe ka lebaka la ho haelloa ke moea.

Litharollo tse ka bang teng

Tabeng ea P0402, hangata batho ba nka sebaka sa valve ea EGR, empa bothata bo khutla. Tharollo e ka bang teng haholo ke ho nkela sensor ea DPFE sebaka.

• Lekola motlakase ho sensor ea DPFE ho EGR e sa sebetseng le e bulehileng.
• Kenya sebaka sa senotlolo sa DPFE.

KHOUTU EA HO HLAHLOBA JOANG MACHHANIC DIAGNOSTIC P0402?

• Skena data e emisa likhoutu le litokomane ho netefatsa bothata.
• E hlakola enjene le likhoutu tsa ETC le liteko tsa litsela ho bona hore na khoutu ea khutla.
• Hlahloba ka mahlo li-vacuum hoses, wiring, likhokahano ho valve ea EGR le solenoid ea taolo, le sensor ea mocheso oa EGR le sensor ea khatello ea morao.
• E thibela le ho etsa liteko haeba vacuum ea EGR e ka sebelisoa ho valve ha solenoid ea taolo e bula ka khanya ho ea ho lebelo le itekanetseng, eseng feela e bulehile ka ho feletseng.
• E lekola converter ea catalytic bakeng sa tšenyo kapa khatello e feteletseng ea morao ho sistimi ea EGR.
• E tlosa valve ea EGR le sensor ea mocheso ho hlahloba hore na carbon e tšoere valve ea EGR e bulehile 'me carbon e thibela EGR purge port, e thibelang valve ho tsoa ka ntle ho vacuum.

LIPHOSO TSE TLOAELEHANG HA HO HLAHLOBA KHOUTU P0402

• Kenya sebaka sa valve ea EGR ntle le ho hlahloba mochine oa khatello ea EGR ho etsa bonnete ba hore o khona ho laola ho buloa ha valve ea EGR.
• Se ke oa hlahloba hore na valve ea EGR e ts'oaroe ke sekotoana sa mashala se bulehileng ka mochini pele u se nkela sebaka.

KHOUTU P0402 E TEHELE KAE?

• Phallo e feteletseng ea khase e nang le phallo e feteletseng e ka etsa hore enjene e thekesele kapa e thekesele ha e ntse e eketseha, kapa ha etsa hore enjene e sebetse ka thata haholo.
• Lebone le kentsoeng la Check Engine le tla etsa hore koloi e hlolehe ho etsa tlhahlobo ea mesi.
• Haeba catalytic converter e koetsoe e baka khoutu, e ka fella ka tahlehelo ea matla kapa enjene e qalang.

KE NTOA EFE E KA LOKELANG KHOUTU P0402?

• Ho fetola valve ea EGR e tsitsitseng
• Ho fetola e robehileng catalytic converter
• Ho fetola sensor ea mocheso oa EGR kapa ho e hloekisa ho tloha ho li-deposit tsa carbon ho e lokisa haeba e ngolisa phetoho e ngata haholo ea mocheso.
• EGR Back Pressure Control Valve Replacement

TLATSETSO HO HLOKOMELA KHOUTU P0402

Khoutu P0402 e qala ha sensor ea mocheso oa EGR e lemoha phetoho e kholoanyane ea mocheso ho feta eo EGR e laetseng ho e bula. Hangata sena se bakoa ke hore EGR backpressure control valve diaphragm e fefoloa ha nako e ntse e feta ke khatello ea morao-rao kapa ntho e thibelang karolo e itseng.
