P0639 - OBD-II Mathata Code Tlhaloso Tlhaloso ea Botekgeniki

Lethathamo la Taolo ea Lits'ebetso tsa Throttle Actuator (Banka ea 2)

Khoutu ea phoso e bolela eng P0639?

Likoloi tse ling tsa sejoale-joale li na le sistimi ea ho laola li-drive-by-wire throttle control e kenyelletsang sensor ho accelerator pedal, module ea taolo ea motlakase / enjene (PCM/ECM), le enjene ea throttle actuator. PCM/ECM e sebelisa sensor ea boemo ba throttle (TPS) ho lekola boemo ba 'nete ba throttle. Haeba boemo bona bo le ka ntle ho boleng bo boletsoeng, PCM/ECM e beha DTC P0638.

Hlokomela hore "banka 2" e bua ka lehlakore la enjene le shebaneng le silinda ea nomoro ea pele. Hangata ho na le valve e le 'ngoe ea throttle bakeng sa banka e' ngoe le e 'ngoe ea li-cylinders. Khoutu P0638 e bonts'a bothata karolong ena ea sistimi. Haeba li-code tsa P0638 le P0639 ka bobeli li fumanoa, sena se ka bontša mathata a marang-rang, ho hloka matla, kapa mathata a PCM/ECM.

Boholo ba li-valve tsena tsa throttle ha li khone ho lokisoa 'me li hloka ho nchafatsoa. 'mele oa throttle hangata o tšoaroa o butsoe ha enjene e hlōleha. Haeba valve ea throttle e fosahetse ka ho feletseng, koloi e ka khannoa feela ka lebelo le tlaase.

Haeba likhoutu tse amanang le sensor ea boemo ba throttle li fumanoa, li tlameha ho lokisoa pele li hlahloba khoutu ea P0639. Khoutu ena e bonts'a phoso tsamaisong ea taolo ea throttle actuator bankeng ea 2 ea enjene, eo hangata e se nang cylinder number one. Li-module tse ling tsa taolo le tsona li ka lemoha phoso ena mme ho bona khoutu e tla ba P0639.

Lisosa tse ka khonehang

Khoutu ea mathata P0639 e ka hlaha ka lebaka la mathata a taolo ea throttle actuator, actuator ka boeona, kapa sensor ea boemo ba throttle. Hape, li-wiring tsa marang-rang tse fosahetseng (CAN), mobu o sa lokelang, kapa mathata a lithapo tsa fatše ho li-module tsa taolo li ka baka molaetsa ona. Lebaka le ka bang teng hape e ka ba sekoli beseng ea CAN.

Hangata, khoutu P0639 e amahanngoa le:

1. Bothata ke sensor ea boemo ba pedal pedal.
2. Bothata ba sensor ea boemo ba throttle.
3. Ho hloleha ha motlakase oa throttle.
4. 'Mele oa throttle o litšila.
5. Mathata a lithapo, ho kenyelletsa le likhokahano tse ka bang litšila kapa tse hlephileng.
6. PCM/ECM (mojule oa taolo ea enjine) ha e sebetse hantle.

Haeba khoutu ea P0639 e etsahala, tlhahlobo e felletseng e tlameha ho etsoa ho fumana sesosa se tobileng le ho nka khato e nepahetseng ea tokiso.

Matšoao a khoutu ea phoso ke afe? P0639?

Matšoao a latelang a ka hlaha ka DTC P0639:

1. Mathata ka ho qala enjene.
2. Li-misfire, haholo-holo ka lisebelisoa tse sa jeleng paate.
3. Enjene e ema ntle le temoso.
4. Ho tsoa ha mosi o motšo ho tsoa tsamaisong ea ho tima ha koloi e qala.
5. Ho senyeha hoa ho potlakisa.
6. Leseli la Check Engine lea khantša.
7. Boikutlo ba ho qeaqea ha o potlakisa.

Mokhoa oa ho fumana khoutu ea phoso P0639?

Sensor ea boemo ba khase e lutse holim'a pedal ka boeona 'me hangata e hokahanngoa ka lithapo tse tharo: 5 V referense voltage, fatše le pontšo. Sheba lithapo bakeng sa khokahanyo e sireletsehileng 'me ha ho matheba a hlephileng. Hape hlahloba fatše ho sebelisa volt-ohmmeter le 5V referense voltage ho tloha PCM.

Matla a pontšo a lokela ho fapana ho tloha ho 0,5 V ha pedal e sa hatelloa ho 4,5 V ha e bulehile ka ho feletseng. Ho ka 'na ha hlokahala ho hlahloba lets'oao ho PCM ho bapisa sensor. Multimeter kapa oscilloscope ea graphical e ka thusa ho tseba hore na phetoho ea motlakase e boreleli hakae nakong eohle ea motsamao.

Sensor ea boemo ba throttle e boetse e na le lithapo tse tharo 'me e hloka ho lekola likhokahano, fatše, le motlakase oa referense oa 5V. Sheba hore na motlakase o fetoha joang ha o tobetsa pedali ea khase. Lekola koloi ea throttle bakeng sa ho hanyetsa, e lokelang ho ba ka har'a litlhaloso tsa fektheri. Haeba khanyetso e sa tloaeleha, motlakase o ka 'na oa se ke oa tsamaea kamoo ho neng ho lebelletsoe.

Enjene ea throttle e sebetsa ho ipapisitse le lets'oao le tsoang sebakeng sa pedal le liparamente tse boletsoeng esale pele tse laoloang ke PCM/ECM. Hlahloba ho hanyetsa motlakase ka ho khaola sehokelo le ho sebelisa volt-ohmmeter ho netefatsa hore e ka har'a litlhaloso tsa feme. Hape hlahloba lithapo u sebelisa setšoantšo sa fektheri ho fumana lithapo tse nepahetseng.

Bakeng sa potoloho ea mosebetsi oa enjene, sebelisa multimeter ea graphing kapa oscilloscope ho netefatsa hore e lumellana le peresente e behiloeng ke PCM/ECM. Ho ka hlokahala sesebelisoa se tsoetseng pele bakeng sa tlhahlobo e nepahetseng.

Lekola 'mele oa throttle bakeng sa boteng ba tšitiso, ditshila kapa mafura a ka sitisang tshebetso ya yona e tlwaelehileng.

Hlahloba PCM/ECM ho sebelisa sesebelisoa sa ho hlahloba hore na lets'oao le lakatsehang la ho kenya, sebaka sa 'nete sa throttle, le boemo ba enjene e shebiloeng li tsamaellana. Haeba boleng bo sa lumellane, ho ka ba le bothata ba ho hanyetsa mohala.

Wiring e ka hlahlojoa ka ho khaola sensor le li-connectors tsa PCM / ECM le ho sebelisa volt-ohmmeter ho hlahloba ho hanyetsa ha likhoele. Liphoso tsa lithapo li ka baka puisano e fosahetseng le PCM/ECM mme tsa baka likhoutu tsa liphoso.

Liphoso tsa tlhahlobo

Ha ho hlahlojoa khoutu ea bothata ea P0639, hangata mechini e mengata e etsa phoso ea ho tsepamisa maikutlo feela matšoao le likhoutu tse bolokiloeng. Mokhoa o atlehang ka ho fetisisa oa ho atamela bothata bona ke ho kenya data ea foreimi ea freeze le ho sekaseka likhoutu ka tatellano eo li bolokiloeng ka eona. Sena se tla u lumella ho tseba ka nepo le ho felisa sesosa sa phoso P0639.

Khoutu ea phoso e tebile hakae? P0639?

Khoutu ea bothata P0639, leha e se kamehla e bakang mathata a potlakileng ts'ebetsong ea koloi, e lokela ho fumanoa le ho lokisoa kapele kamoo ho ka khonehang. Haeba e sa rarolloe, khoutu ena e ka qetella e lebisa mathateng a tebileng joalo ka ha enjene e sa qale kapa ho ema ka tsela e sa tloaelehang. Ka hona, ho kgothaletswa ho etsa tlhahlobo le ho lokisa ho thibela mathata a ka bang teng.

Ke tokiso efe e tla thusa ho felisa khoutu? P0639?

Ho rarolla le ho seta khoutu ea P0639 bocha, ho khothaletsoa hore mochini oa hau a etse mehato e latelang ea tokiso:

1. Kenya sebaka sa likhoele leha e le life tse senyehileng kapa tse senyehileng, lihokelo kapa likarolo tse amanang le sistimi ea throttle.
2. Haeba ho se sebetse hantle ha throttle valve drive motor e fumanoa, e lokela ho nkeloa sebaka ke e sebetsang.
3. Haeba ho hlokahala, nka sebaka sa 'mele oohle oa throttle, ho kenyelletsa le sensor ea boemo ba throttle, joalokaha e khothalelitsoe ke moetsi.
4. Ha o nkela 'mele oa throttle sebaka, mochine o lokela ho nahana ka ho nkela sensor ea pedal sebaka, haeba ho boletsoe.
5. Fetola li-module tsohle tse fosahetseng tsa taolo, haeba li fumaneha.
6. Hokela kapa ho khutlisetsa lihokelo life kapa life tse hlephileng, tse jeleng kapa tse senyehileng tsamaisong.
7. Kenya sebaka sa lithapo life kapa life tse nang le phoso borokhong ba libese ba CAN haeba ho tsejoe hore ke mohloli oa bothata.

Ho hlahlojoa ka hloko le ho kenya ts'ebetsong mehato e boletsoeng ho tla thusa ho felisa khoutu ea P0639 le ho khutlisetsa koloi ts'ebetsong e tloaelehileng.
