Sensor Speed ​​​​Sensor Range / Ts'ebetso

Khoutu ea phoso e bolela eng P0721?

Khoutu ea mathata P0721 ke khoutu e tloaelehileng ea tlhahlobo ea phetisetso ea OBD-II e sebetsang ho likoloi tsa mefuta e fapaneng e kang VW, BMW, Mercedes, Chevrolet, GMC, Allison, Duramax, Dodge, Ram, Ford, Honda, Hyundai, Audi le tse ling. . Le hoja ka kakaretso ka tlhaho, mehato e khethehileng ea ho lokisa e ka fapana ho itšetlehile ka selemo, ho etsoa, ​​mohlala le thepa ea koloi. Khoutu ea P0721 e amana le sensor ea lebelo la phetisetso mme ts'ebetso ea eona e ka bakoa ke liphoso tse fapaneng tse kang P0720, P0722 le P0723, tse bonts'ang mathata a itseng.

Morero oa sensor ea lebelo la phetisetso ke ho fana ka tlhaiso-leseling ea lebelo la phetisetso ho PCM (mojule ea taolo ea enjine). Lintlha tsena lia hlokahala ho laola li-solenoids tsa shift le ho lekola ts'ebetso ea ho fetoha ha gear, khatello ea phetisetso le, maemong a mang, lebelo la lebelo.

Likoloi tse nang le phetisetso e laoloang ke elektroniki, sensor ea lebelo la tlhahiso (OSS) e teng qetellong ea shaft e hlahisoang. E lekanya lebelo la ho potoloha ha shaft, e leng bohlokoa bakeng sa ho tseba nako ea ho fetoha ha gear le ts'ebetso ea torque converter.

Ha PCM/ECM e etsa qeto ea hore sensor ea OSS ha e sebetse hantle kapa haeba e le ka ntle ho mefuta e tloaelehileng, e ka etsa hore khoutu ea P0721 e behe. Khoutu ena e bonts'a mathata a phetisetso a ka bang teng mme e ka baka ts'ebetso e fosahetseng ea converter ea torque, nako ea ho fetoha, le likarolo tse ling.

Lisosa tse ka khonehang

Lisosa tsa khoutu ea P0721 li kenyelletsa:

1. Mathata ka lithapo kapa likhokahano.

Liphoso tsena li ka lebisa tlhokomelong e fosahetseng le litšenyehelong tse sa hlokahaleng bakeng sa ho nkela likarolo tse ling sebaka seo ha e le hantle se nang le phoso.

Khoutu ea phoso e tebile hakae? P0721?

Khoutu ea mathata P0721 e amanang le sensor ea lebelo la phetisetso e ka ba e tebileng mme e ka ama ts'ebetso e tloaelehileng ea koloi. Mona ke lintlha tse 'maloa tse ka totobatsang botebo ba khoutu ena:

1. Tahlehelo ea Moruo oa Mafura: Kaha khoutu ena e amana le ts'ebetso ea phetisetso, boteng ba eona bo ka fella ka liphetoho tse fosahetseng tsa lisebelisoa le tahlehelo ea moruo oa mafura.
2. Kotsi ea Karohano ea Phetisetso: Baetsi ba lokiselitse litsamaiso tsa taolo ea phetisetso hore li fetole likere ka nepo ho ipapisitse le kenyeletso e tsoang ho sensor ea lebelo la tlhahiso. Ho se sebetse hantle ha sensor ena ho ka etsa hore ho be le liphetoho tse thata kapa tse fosahetseng, tse ka lebisang ho senya le ho senya phetisetso.
3. Bothata ba ho Ts'oara: Baetsi ba ka sebelisa data ho tsoa ho sensor speed speed ho lokisa ts'ebetso ea enjene le phetisetso maemong a fapaneng. Sensor e fosahetseng e ka ama tsela eo koloi e sebetsang ka eona.
4. Limp Mode: Maemong a mang, ha khoutu ea P0721 e fumanoa, tsamaiso ea koloi e ka 'na ea kenya koloi boemong bo fokolang, e leng ho tla fokotsa ts'ebetso ea eona le lebelo ho thibela tšenyo e eketsehileng.

Kahoo, khoutu P0721 e lokela ho nkoa e le ea bohlokoa 'me e hloka tlhokomelo ea hang-hang. Ho qoba mathata le tšenyo e eketsehileng, ho kgothaletswa hore o buisane le makheneke mme o etse hore e hlahlojwe le ho e lokisa ha ho hlokahala.

Ke tokiso efe e tla thusa ho felisa khoutu? P0721?

Ho ka hlokahala lethathamo le latelang la litokiso ho rarolla DTC P0721:

1. Output Speed ​​​​Sensor (OSS) Hlahloba: Mochini o lokela ho lekola boemo le ho kenya sensor ea lebelo la tlhahiso ka nepo. Haeba sensor e sa sebetse, e lokela ho nkeloa sebaka ke e ncha.
2. Ho hlahloba Input Shaft Speed ​​​​Sensor: Mochine o lokela ho lekola boemo le ts'ebetso e nepahetseng ea sensor ea lebelo la shaft. Haeba e fosahetse, e tlameha ho nkeloa sebaka.
3. Ho hlahloba Sensor ea Mocheso oa Mokelikeli oa Phetiso: Mokelikeli oa mocheso oa mocheso oa mocheso o ka ama ts'ebetso ea tsamaiso ea tsamaiso ea phetisetso. Haeba e fosahetse, e lokela ho nkeloa sebaka.
4. Ho lekola likhokahano tsa Motlakase le Lithapo: Mochine o lokela ho hlahloba likhokahano tsohle tsa motlakase, likhoele, le likhokahanyo tse amanang le lisensara le sistimi ea taolo ea phetisetso. Haeba tšenyo e fumanoa, ho ka 'na ha hlokahala hore ho khutlise likhoele kapa ho lokisoe.
5. Ho hlahloba Boemo le Boemo ba Mokelikeli oa Phetiso: Boemo kapa boemo bo sa nepahalang ba mokelikeli oa phetiso bo ka ama ts'ebetso ea li-sensor le sistimi ea taolo. Haeba ho hlokahala, mokelikeli o lokela ho nkeloa sebaka 'me boemo bo phahamisetsoe boemong bo hlokahalang.
6. Sheba likaroloana tsa tšepe ka har'a mokelikeli oa phetiso: Likaroloana tsa tšepe ka har'a mokelikeli li ka bontša mathata ka har'a phetiso. Tabeng ena, phetiso e ka 'na ea hloka ho lokisoa kapa ho nkeloa sebaka.
7. Hlakola le ho seta botjha khoutu ya mathata: Kamora ho qeta mosebetsi wa tokiso, mak'henike o lokela ho skena sisteme le ho seta khoutu ya phoso ya P0721 botjha.

Ka kopo hopola hore mehato e tobileng le boholo ba mosebetsi li ka fapana ho itšetlehile ka ho etsoa, ​​​​moetso le tlhophiso ea koloi. Ho bohlokoa ho ba le mochini o nang le boiphihlelo kapa lebenkele la ho lokisa likoloi le ho le lokisa ho rarolla khoutu ena ea mathata.
