P0179 - OBD-II Mathata Code Tlhaloso Tlhaloso ea Botekgeniki

Kenyelletso e phahameng ea sensor ea sebopeho sa mafura

DTC P0179 e bolela'ng?

Code P0179 tsamaisong ea OBD-II e emetse "Diesel Fuel Sensor Circuit Input High," eo ka tloaelo e bontšang hore ho na le bokhutšoanyane ho sensor kapa wiring e bakang motlakase o phahameng.

DTC ena e sebetsa ho mefuta e fapaneng ea likoloi tse nang le sistimi ea OBD-II, ho kenyelletsa Ford, BMW, Chevy, Pontiac, Mazda, VW, Honda, Scion, Land Rover le tse ling. Ho na le likhoutu tse ling tse tharo tse amanang le sebopeho sa sensor ea potoloho ea mafura: P0176, P0177, le P0178. Potoloho ena, eo hape e tsejoang e le flex fuel sensor circuit, e lekola litaba tsa ethanol tsa peterole ka enjene ea mafura a flex. Ethanol e ka 'na ea fapana ka ho tlatsa ka' ngoe, 'me potoloho ea sensor ea mafura e fetisetsa lipontšo ho ECM ho latela boemo ba ethanol. ECM (Engine Control Module) e laola ho tima mollo le ente ea mafura bakeng sa ts'ebetso e nepahetseng le moruo oa mafura.

Khoutu ea P0179 e qala ha ECM e bona voltage e phahameng ho potoloho ea sensor ea mafura. Hangata sena se bontša bothata ba motlakase.

Ho feta moo, PCM (mojule ea taolo ea enjine) e beha leihlo maemo a ethanol a mafura, mme ha boemo ba ethanol bo feta 10% ka peterole, bo ka baka P0179. Likoloi tse ling li ka sebelisa maemo a phahameng a ethanol (ho fihla ho 85%) mafura, empa sena se ipapisitse le mohlala le lintlha tsa koloi.

Ha sena se etsahala, mochine oa motsoako oa mafura o romela lipontšo ho PCM e bontšang hore ho na le bothata, 'me ha e arabela, PCM e hlahisa khoutu ea phoso ea P0179 'me e kenya Leseli la Check Engine.

Kenyelletso e phahameng ho potoloho ea sensor e ka ba le lisosa tse fapaneng, ho kenyelletsa tšilafalo ea mafura, mathata a khokahano, mathata a sensor, kapa esita le lithapo tse qhibilihisitsoeng tse ka bakang potoloho e khuts'oane.

Lisosa tse Tloaelehileng tsa Khoutu ea Mathata P0179

Tšilafalo ea mafura ke sesosa se atileng haholo sa khoutu ea bothata ea P0179. Lisosa tse ling tse ka hlahang li kenyelletsa:

• Lihokelo tsa terata tse senyehileng, tse bulehileng kapa tse khutsufalitsoeng.
• Sensor ea sebopeho sa mafura e fosahetse.
• PCM e fosahetseng (e sa tloaelehang).

Matšoao a khoutu P0179 ke afe?

Boemo ba ho tiea ba khoutu ena ea P0179 bo itekanetse. Matšoao a amanang le khoutu ena a ka kenyelletsa:

• Keketseho ea tšebeliso ea mafura.
• Ts'ebetso e tlase ea enjene.
• Letšoao la ho tima le hlahloba enjene.
• Maemo ao enjene e sa qaleng hang ka mor'a ho leka ho qala.

Ho hlakile hore ts'ebetso ea Leseli la Check Engine ke letšoao le atileng haholo la bothata. Ha e le matšoao, a ka fapana ho tloha ho a tloaelehileng ho isa ho a matla, ho itšetlehile ka mofuta oa sesosa.

Ke habohlokoa ho hlokomela hore metsi a feteletseng ka mafura a ka baka mathata a ts'ebetso ea enjene, haholo-holo haeba sensor e sitoa ho lemoha boteng bona.

Mochine o hlahloba khoutu ea P0179 joang?

Mochine oa likoloi o etsa liketso tse latelang:

1. Likhoutu tsa liphoso tse skena le li-log li emisa data ea foreimi.
2. E hlakola likhoutu ho hlahloba hore na phoso ea khutla.

E boetse e etsa tlhahlobo ea pono ea wiring ea sensor le likhokahano bakeng sa li-circuits tse khutšoane tse ka bang teng.

Haeba ho hlokahala, e hakolla khokahano ho sensor mme e hlahlobe ho bona hore na khokahano ea sensor e silafetse kapa e silafetse, e ka bakang potoloho e khuts'oane.

Tlhokomeliso: Mohato oa pele oa ho rarolla mathata ke ho hlahloba Li-Bulletin tsa Tšebeletso ea Tekheniki tse sebetsang selemo sa koloi ea hau, mohlala, le powertrain. Sena se ka boloka nako e ngata 'me sa u lebisa tseleng e nepahetseng bakeng sa litokiso.

Liphoso tsa tlhahlobo

Ho thibela tlhahlobo e fosahetseng, latela litataiso tsena:

1. Lekola likhokahano tsa sensor ka hloko ho netefatsa khokahano e ntle. Hoa etsahala hore kamora ho sebeletsa filthara, khokahano e kanna ea se ke ea tiisoa ka mokhoa o sireletsehileng, 'me mabitso a sensor kapa sehokelo a ka kobeha.
2. Tlosa sehokelo sa sensor 'me u hlahlobe sistimi hape. Haeba khoutu ea P0179 e nyamela 'me e nkeloa sebaka ke khoutu ea P0178 kapa P0177, e ka bontša hore mohala ha o khutsufatsoe.

Ke litokiso life tse tla thusa ho lokisa khoutu ea P0179?

Latela mehato ena:

1. Hlakola sefe ea mafura 'me u e hloekise.
2. Sheba likhoutu tsa mabone a enjene.
3. Tlosa sensor e fosahetseng kapa e khuts'oane.
4. Lokisa lithapo tse khutsufalitsoeng kapa tse chesitsoeng kapa khokahanyo ho sensor.
5. Kenya sebaka sa "fuel filter" lebokoseng ka sensor 'me u hlakole likhoutu.
6. Kenya sebaka sa tanka ea mafura.
7. Tlosa mafura a silafetseng.
8. Hloekisa likhokahano ho tsoa ho kutu.
9. Haeba ho hlokahala, lokisa kapa u nke sebaka sa mohala.
10. Fetola lithapo tsa mafura kapa li-fittings.
11. Kenya sebaka sa sensor ea sebopeho sa mafura.
12. Nahana ka ho benya kapa ho nkela ECM sebaka.

Khoutu P0179 e kanna ea se tloaelehe haholo 'me e ka bonts'a metsi ka har'a mafura. Hape, joalo ka ha u boletse, e ka khoptjoa haeba khokahano e khutsufalitsoe kapa likhokahano li sa etse khokahano e nepahetseng. Ka hona, ho bohlokoa ho hlahloba ka hloko le ho lokisa mathata a likhoele le likhokahanyo le ho etsa bonnete ba hore mafura a hloekile ebile ha a na metsi ho qoba tlhahlobo e fosahetseng le ho nkela likarolo tse ling tse sa hlokahaleng.
