Matšoao a khoutu ea phoso ke afe? P0454?

Letšoao le ka sehloohong la khoutu ea P0454 ke hore leseli la Check Engine lea hlaha. Leha ho le joalo, pele kapa ka mor'a hore sesupo se bulehe, u ka 'na ua se ke ua hlokomela ho se sebetse hantle ha koloi.

Matšoao a khoutu ena a ka kenyelletsa ho fokotseha ho fokolang ha ts'ebetso ea mafura le MIL e bonesitsoeng (lebone la ho se sebetse hantle). Maemong a mangata ka khoutu ea P0454, ha ho na matšoao.

Ho bohlokoa ho hlokomela hore likhoutu tse fapaneng tsa liphoso tse joalo ka P0442, P0451, P0452, P0453 le tse ling tse amanang le sistimi ea "evaporative emission control" (EVAP) ea koloi e kanna ea ba thata ho bonts'a matšoao. Leha ho le joalo, ho hlokomoloha khoutu ha e hlaha ho ka senya tsamaiso ea EVAP.

Ka hona, ho kgothaletswa ho tseba lisosa tsa khoutu ea P0454 le ho nka mehato e hlokahalang ho e felisa. Leha ho le joalo, haeba u fumana khoutu ena ka koloing ea hau, hoa utloahala ho etsa tlhahlobo le ho lokisa ho boloka botšepehi le katleho ea tsamaiso ea EVAP.

Mokhoa oa ho fumana khoutu ea phoso P0454?

Ho fumana khoutu ea P0454, o tla hloka lisebelisoa le lits'ebetso tse latelang:

1. OBD II Diagnostic Scanner: Hokela sesebelisoa sa ho skena boema-kepeng ba koloi ea OBD II ho skena sistimi ea khomphutha e holim'a board bakeng sa khoutu ea P0454.
2. Digital Volt / Ohmmeter: Sesebelisoa sa ho hlahloba lipotoloho tsa motlakase, lithapo le likhokahanyo. Sena se tla thusa ho tseba khefu kapa lipotoloho tse khutšoane tsamaisong.
3. Boitsebiso ba Koloi: Mohloli o tšepahalang oa tlhahisoleseling mabapi le koloi ea hau, joalo ka All Data DIY kapa bukana ea lits'ebeletso bakeng sa moetso oa hau o ikhethileng.
4. Mochini oa mosi (haeba ho hlokahala): Sesebelisoa se thusang ho tseba ho lutla ho sistimi ea EVAP, haholo haeba ho sa bonahale ka tlhahlobo ea pono.

Mokhoa oa ho hlahloba:

1. Tlhahlobo ea pono: Sheba li-hoses, lithapo, lithapo tsa motlakase le likhokahano ho sistimi ea EVAP. Ela hloko likarolo tse ka 'nang tsa senyeha kapa tse haufi le likarolo tsa tsamaiso ea mocheso o chesang. Hape etsa bonnete ba hore sekoahelo sa khase se koetsoe ka thata.
2. Ho hokela seskena: Hokela sehatisi boema-kepeng ba tlhahlobo ea koloi 'me u fumane likhoutu tsohle tse bolokiloeng ebe u emisa data ea foreimi. Ngola lintlha tsena fatše.
3. Seta dikhoutu botjha le teko drive: Hlakola likhoutu ho sekena 'me u leke koloi ho fihlela khoutu e hlakoloa kapa mokhoa oa OBD-II Ready o hlaha. Likhoutu tsa EVAP hangata lia hlaka ka mor'a lipotoloho tse 'maloa tsa ho khanna ntle le phoso.
4. Tlhokomelo ea khatello ea EVAP: Sheba lets'oao la sensor ea khatello ea EVAP u sebelisa phallo ea tlhahlobo ea skena. Etsa bonnete ba hore khatello ea tsamaiso e kopana le litlhaloso tsa moetsi.
5. Ho hlahloba sensor ea khatello ea EVAP: Haeba khoutu e bontša bothata ka sensor ea khatello ea EVAP, e hlahlobe. Sensor hangata e fumaneha kaholimo ho tanka ea mafura. Latela likhothaletso tsa moetsi bakeng sa tlhahlobo le ho khutlisa sensor ha ho hlokahala.
6. Ho hlahloba lipotoloho tsa motlakase: Hakolla balaoli bohle ba amehang 'me u leke lipotoloho ka bomong u sebelisa volt/ohmmeter ea dijithale. Fetola kapa u lokise li-circuits tse bulehileng kapa tse khuts'oane ha ho hlokahala.

Lintlha tse ling: Khatello e tlase kapa e phahameng ea sistimi ea EVAP e ka baka P0454. Etsa bonnete ba hore khatello e ka har'a litlhahiso tsa moetsi. Haeba sensor ea khatello ea EVAP e fosahetse, e nkele sebaka.

Lisebelisoa tse hlokahalang ho fumana khoutu ea P0454 li kenyelletsa:

1. OBDII Scanner: Ho skena sistimi ea khomphutha e kahare le ho bona khoutu ea P0454.
2. Digital Volt / Ohmmeter: Ho hlahloba lipotoloho tsa motlakase le lihokelo.
3. Boitsebiso ba Koloi: Mohloli o tšepahalang oa tlhahisoleseling mabapi le koloi ea hau, joalo ka All Data DIY kapa buka ea litšebeletso
