P0446 - OBD-II Mathata Code Tlhaloso Tlhaloso ea Botekgeniki

Ho se sebetse hantle ha potoloho ea potoloho ea mouoane emission

Khoutu ea phoso e bolela eng P0446?

Khoutu ea mathata P0446 e amana le sistimi ea taolo ea mouoane oa mouoane (EVAP) mme hangata e bonts'a bothata ka valve ea moea. Sephahla sena se na le boikarabelo ba ho boloka khatello le ho thibela mouoane oa mafura hore o se ke oa tsoa tsamaisong. Haeba e sa sebetse hantle, e ka baka likhoutu tse fapaneng tsa liphoso ho tloha ho P0442 ho isa P0463. Litokiso li kenyelletsa ho nkela kapa ho lokisa valve ea moea, ho hlahloba potoloho ea taolo, le mehato e meng ea tlhahlobo.

Lisosa tse ka khonehang

Khoutu ea bothata P0446 e ka bonts'a mathata a latelang:

1. Sephahla se nang le phoso.
2. Mathata le potoloho ea taolo ea li-valve tsa ho qeta, joalo ka ho hanyetsa ho bulehileng, ho khuts'oane kapa ho fetelletseng.
3. Ventilation valve e koetsoe.
4. Ho ka 'na ha e-ba le mathata ka PCM (mojule oa software ea taolo ea enjene).

Lisosa tse tloaelehileng haholo tsa khoutu ena ea phoso ke valve e nang le phoso kapa e koetsoeng, mathata a potoloho ea taolo joalo ka mehala e fosahetseng. Hape hlokomela hore ho ka 'na ha e-ba le lintlha tse ling tse kang khase ea khase e sieo, ho sebelisa sekoahelo se fosahetseng sa mafura, kapa tšitiso ea khase ea khase.

Matšoao a khoutu ea phoso ke afe? P0446?

Khoutu ea phoso ea P0446 hangata e iponahatsa ka matšoao a latelang:

1. Lebone la enjine ea cheke (MIL) kapa lebone le sa sebetseng hantle setsing sa lisebelisoa lea hlaha.
2. Tsebiso e ka bang teng ea monko oa mafura, haholo-holo ha u eme haufi le koloi.

Khoutu ena e bonts'a bothata ka valve ea ho tima mouoane oa mouoane (EVAP). Leha ho le joalo, ho bohlokoa hape ho hlokomela hore mathata a mang a koloi a ka etsa hore khoutu ena e hlahe, joalo ka sekoti sa mashala se fosahetseng, li-hoses tse koetsoeng kapa tse senyehileng kapa li-filters, kapa mochine o fosahetseng oa khatello ea tsamaiso ea EVAP. Sena se ka boela sa baka likhoutu tse ling tsa liphoso tse amanang le sistimi ea EVAP.

Mokhoa oa ho fumana khoutu ea phoso P0446?

Ho kgothaletswa hore o ikopanye le setsebi ho hlahloba le ho rarolla khoutu ya P0446. Ba tlameha ho phethahatsa mehato e latelang:

1. Hlakola koloi ho netefatsa hore khoutu P0446 ke eona feela bothata.
2. Sheba boemo ba sekoahelo sa khase, u se nkele sebaka ha ho hlokahala.
3. Lekola sistimi ea EVAP bakeng sa ho lutla o sebelisa jenereithara ea khatello ea mosi.
4. Sheba boemo ba valve ea ho laola moea oa EVAP, ho e hloekisa kapa ho e nkela sebaka ha ho hlokahala.
5. Etsa bonnete ba hore ho na le matla le fatše ho potoloho ea taolo.
6. Leka ho tiisa sekoahelo sa khase le ho hlakola khoutu ea phoso haeba e senyehile.
7. Haeba khoutu ea P0446 e phehella ka mor'a mehato e ka holimo, ho ka 'na ha hlokahala liteko tse ngata tsa tlhahlobo ea mafu.

Hape ke habohlokoa ho hlokomela hore khoutu ea P0446 e ka hlaha ka lebaka la mathata a mang le tsamaiso ea EVAP, kahoo ke habohlokoa ho etsa mosebetsi oohle o hlokahalang oa ho hlahloba ho tseba hantle motso oa bothata.

Liphoso tsa tlhahlobo

Karolwana ea sengoloa "Liphoso ha ho hlahlojoa P0446":

Ka Phoso Ho Hlokomoloha Li-DTC Tse Ling: Ka linako tse ling mechanics e ka tsepamisa maikutlo ho khoutu ea P0446 feela ha e ntse e shebile likhoutu tse ling tse amanang joalo ka P0442 kapa P0455 tse ka bonts'ang mathata a amanang le sistimi ea EVAP. Sena se ka lebisa tlhahlobong e fosahetseng le tharollo ea sesosa sa khoutu ea P0446. Ka hona, ho bohlokoa ho hlahloba ka hloko likhoutu tsohle tsa liphoso le ho etsa tlhahlobo e felletseng ea sistimi ea EVAP ho tseba liphoso ka nepo.

Khoutu ea phoso e tebile hakae? P0446?

Bohloko ba khoutu ea P0446, leha e le nyane, ha bo bolele hore e lokela ho hlokomolohuoa. Mathata ka sistimi ea koloi ea hau ea EVAP qetellong a ka senya likarolo tse ling tsa bohlokoa tsa koloi mme a etsa hore ho hlahe likhoutu tse ling tsa liphoso. Ka hona, ke habohlokoa ho nka khoutu ena ka botebo 'me u ikopanye le mochine o tšoanelehang bakeng sa tlhahlobo ea setsebi le ho lokisoa hang ha e hlaha. Sena se tla thusa ho thibela mathata a mang le ho boloka koloi ea hau e sebetsa hantle.

Ke tokiso efe e tla thusa ho felisa khoutu? P0446?

Ho rarolla khoutu ea P0446, o ka nka mehato e latelang:

1. Sheba sekoahelo sa khase: Etsa bonnete ba hore se koetsoe ka mokhoa o sireletsehileng 'me ha se senyehe. Tlosa sekoahelo haeba se senyehile.
2. Sheba Potoloho ea Taolo: Hlahloba potoloho ea taolo ea valve ea EVAP. Fumana le ho lokisa ho bula, lifupi, kapa ho hanyetsa ho feteletseng ho potoloha.
3. Sheba valve ea moea ea EVAP: Sheba valve ka boeona bakeng sa li-clog kapa liphoso. E hloekise kapa e khutlise ha ho hlokahala.
4. Sheba lithapo: Sheba boemo ba mohala bakeng sa khefu, li-circuits tse khutšoane kapa tšenyo. Ela hloko ka ho khetheha mohala o eang ho valve ea moea.
5. Hlahloba PCM: Maemong a mang, bothata bo ka 'na ba bakoa ke mojule oa taolo ea enjene e fosahetseng (PCM). E hlahlobe hore na ha e sebetse hantle.
6. Ho lokisa kapa ho fetola likaroloana: Ho itšetlehile ka liphello tsa ho hlahloba, ho ka 'na ha hlokahala ho lokisa kapa ho nkela sebaka se le seng kapa tse ngata tsa tsamaiso ea EVAP, ho akarelletsa le valve ea vent, wiring, kapa PCM.
7. Hlakola Khoutu: Kamora ho qeta tokiso, hlakola khoutu ea P0446 u sebelisa sekena ho hlakola liphoso.

Hopola, ho kgothaletswa hore o ikopanye le mak'henike a tshwanelehileng kapa lebenkele la ho lokisa dikoloi bakeng sa ho hlahlojwa ka nepo le ho lokiswa, haholoholo haeba o sa kgodisehe ka bokgoni ba hao ba ho lokisa koloi.
