Exhaust khase e laolang valve "A" e tlaase

Khoutu ea phoso e bolela eng P0477?

Bothata ba P0477 bo amana le taolo e tlaase ea khatello ea khatello ea motlakase 'me e ka etsahala ka likoloi tse sa tšoaneng, ho akarelletsa Ford, Dodge, Mercedes, Nissan le VW. Khoutu ena e bonts'a motlakase o fosahetseng o baloang ke sensor ea khatello ea khase ea exhaust mme e romelloa mojuleng oa taolo ea enjene (PCM). Haeba motlakase ona o le ka tlase ho tloaelehileng, PCM e boloka khoutu ea P0477.

The exhaust backpressure valve e laola exhaust backpressure, e thusang ho eketsa ho futhumala ha ka hare le ho fokotsa nako ea ho felloa ke moea ha mocheso oa mocheso o tlase o le teng. The Engine Control Module (ECM) e sebelisa tlhahisoleseding e mabapi le ho ntša metsi ka morao, mocheso oa moea o kenang, mocheso oa oli ea enjene, le mojaro oa enjene ho laola valve. Valve e laoloa ka potoloho ea tlhahiso ea 12V ka hare ho ECM.

Maemong a tlase a mocheso le maemo a itseng, valve e ka 'na ea lula e koetsoe ka mokhoa o itseng, e leng se etsang hore hare-hare ho futhumale. Ha enjene le oli li ntse li futhumala, valve e laola khatello ea morao ea ho tsoa. Ho rarolla mathata P0477 ho ka 'na ha hloka ho hlahloba mohala, valve le likarolo tse ling tsa tsamaiso ea ho laola khase.

Lisosa tse ka khonehang

Khoutu ena ea mathata (P0477) e ka hlaha ka lebaka la mathata a 'maloa a ka bang teng:

1. The exhaust manifold check valve e fosahetse.
2. Wiring e kopanyang valve ea ho hlahloba e tsoang ka bongata e ka 'na ea buleha kapa ea khutsufatsoa.
3. Mathata ka har'a potoloho ea li-valve tsa ho cheka tse ngata, joalo ka khokahano e mpe ea motlakase.
4. Matla a sa lekaneng a potoloho ea matla pakeng tsa solenoid ea khatello ea khase le PCM (Powertrain Control Module).
5. Bula potolohong ea phepelo ea motlakase lipakeng tsa solenoid ea khatello ea khase le PCM.
6. Nako e khuts'oane ho ea fatše ka har'a potoloho ea phepelo ea motlakase ea motlakase oa taolo ea khatello ea khase ea motlakase.
7. Relay ea taolo ea khatello ea khase ea exhaust e fosahetse.
8. Bothata bo ka bang teng ka taolo ea khatello ea khase ea solenoid kapa bothata le PCM (le hoja sena se ke ke sa etsahala).

Ho rarolla khoutu ena ea phoso, tlhahlobo e tlameha ho etsoa, ​​​​ho qala ka ho hlahloba likhokahano tsa mehala le motlakase, le ho tsoela pele ka ho lekola likarolo tsa sistimi ea taolo ea khase e tsoang joalo ka li-valve tsa tlhahlobo ea manifold exhaust, solenoids le relays. Sesosa se ka 'nang sa etsahala haholo ke phoso ea lithapo kapa likarolo tsa motlakase tsa sistimi.

Matšoao a khoutu ea phoso ke afe? P0477?

Matšoao a amanang le khoutu ea P0477 a ka kenyelletsa:

1. Leseli la Malfunction Indicator (MIL) kapa "Check Engine" lea hlaha.
2. Ho hloka matla a enjene a hlokahalang.
3. Ho lahleheloa ke ts'ebetso ea enjene, ho kenyelletsa le mathata a ka bang teng a ho hula.
4. Nako e eketsehileng ea ho futhumatsa enjene e batang.

Matšoao ana a ka 'na a bontša mathata a tlaase a khatello tsamaisong ea ho laola khatello ea metsi.

Mokhoa oa ho fumana khoutu ea phoso P0477?

Ho loantša khoutu ea phoso P0477, ho kgothaletswa ho latela mehato ena:

1. Sheba le ho lokisa phala e koetsoeng ka morao ea khatello.
2. Lokisa, hloekisa kapa u nke sebaka sa sensor ea exhaust backpressure.
3. Lokisa kapa u nke sebaka sa valve ea ho hlahloba khatello ea khase e tsoang.
4. Hlahloba, 'me, ha ho hlokahala, u lokise lithapo life kapa life tse khutsufalitsoeng kapa tse khaotsoeng tsa khatello ea motlakase.
5. Sheba khokahanyo ea motlakase seketjaneng sa valve ea khatello ea morao. Lokisa kapa chencha ha ho hlokahala.
6. Kenya sebaka sa solenoids ea khatello ea mokokotlo e sothehileng.
7. Lokisa kapa fetola likarolo tsa motlakase tse senyehileng joalo ka mehala le likhokello.
8. Haeba mehato e meng kaofela e hlōleha, nahana ka ho tsosolosa PCM e fosahetseng (mojule oa taolo ea enjene), leha sena se ke ke sa etsahala.
9. Hape ke habohlokoa ho hlahloba le ho lokisa mathata a amanang le likhoutu tse ling tsa phoso ho PCM tse ka 'nang tsa amana le tsamaiso ea khatello ea morao ea ho tima.
10. Pele o etsa mehato ena, ho kgothaletswa hore o hlahlobe Bulletin ya Tshebeletso ya Setsebi (TSB) bakeng sa koloi ya hao e itseng ho netefatsa hore moetsi wa koloi ha a fane ka firmware ya PCM kapa reprogramming ho rarolla bothata bona.
11. Hopola ho etsa liteko ka sesebelisoa sa ho hlakola DTC mohopolong le ho bona hore na khoutu ea P0477 ea khutla ka mor'a hore ho etsoe tokiso.
