Mokhoa oa ho fumana khoutu ea phoso P0840?

Ho utloisisa khoutu ea P0840 ho ka ba thata. Ha phoso ena e hlaha, ho ka 'na ha e-ba le mathata ka wiring, sensor ea TFPS, TCM, kapa mathata a ka hare a phetisetso. E kgothaletswa ho qala ka ho hlahloba Tekheniki Service Bulletins (TSBs) le ho etsa tlhahlobo ea pono ea TFPS sehokelo le wiring. Bakeng sa tlhahlobo, o ka sebelisa voltmeter ea digital (DVOM) le ohmmeter. Haeba ho na le liphoso tse fumanoeng, likarolo tse amehang li lokela ho nkeloa sebaka 'me likarolo tsa PCM/TCM li hlophiselitsoe koloi ea hau. Haeba u belaela, ho molemo ho ikopanya le setsebi sa tlhahlobo ea likoloi se tšoanelehang.

Liphoso tsa tlhahlobo

Ha ho hlahlojoa khoutu ea P0840, liphoso tse tloaelehileng li ka kenyelletsa:

1. Ho hlahloba lintlha tse sa lekaneng tsa lits'ebeletso tsa tekheniki (TSBs) bakeng sa litaba tse tsebahalang le litokiso tse amanang le khoutu ena.
2. Tlhahlobo e sa phethahalang kapa e futsanehileng ea lithapo le li-connectors tse lebisang ho transmission fluid pressure sensor (TFPS).
3. Tlhaloso e fosahetseng ea liphetho tsa tlhahlobo, haholo-holo mabapi le litlhaloso tsa moetsi bakeng sa ho hanyetsa le motlakase.
4. Ho hloleha ho hlahloba mathata a phetiso ea ka hare joalo ka ho lutla, ho thibela khatello kapa mathata a 'mele oa valve.
5. Ho hlokomoloha ho hlophisa hantle kapa ho lekanya PCM/TCM ka mor'a ho fetola likarolo.

Ka lebaka la bothata ba ho hlahloba bothata bona, ho khothalletsoa hore u ikopanye le setsebi se tšoanelehang kapa lebenkele la ho lokisa likoloi bakeng sa tlhahlobo e nepahetseng le e sebetsang hantle le ho lokisoa.

Khoutu ea phoso e tebile hakae? P0840?

Khoutu ea bothata P0840 e bonts'a bothata tsamaisong ea taolo ea phetisetso e amanang le mochini oa khatello ea mokelikeli oa phetisetso / switch. Ho itšetlehile ka sesosa se tobileng le maemo a tšebeliso ea koloi, boima ba khoutu ena bo ka fapana. Tse ling tsa litlamorao tse ka bang teng li ka kenyelletsa ho feto-fetoha ha lisebelisoa tse sa tloaelehang, tšebeliso e eketsehileng ea mafura, kapa mathata a mang a phetisetso.

Ke habohlokoa ho ela hloko matšoao 'me u qale ho hlahloba le ho lokisa hang-hang ho qoba ho mpefatsa bothata le tšenyo e ka bang teng phetisong. Ho khothalletsoa ho ikopanya le setsebi se tšoanelehang bakeng sa tlhahlobo e nepahetseng haholoanyane le ho rarolla mathata.

Ke tokiso efe e tla thusa ho felisa khoutu? P0840?

Litokiso tse latelang li ka hlokoa ho rarolla khoutu ea P0840:

1. Sheba 'me u nkele lithapo tse senyehileng kapa tse robehileng sebakeng sa transmission fluid pressure sensor/switch (TFPS).
2. Ho nkela sebaka sa sensaro sa khatello ea mokelikeli o fosahetseng.
3. Ho hlahloba le ho sebeletsa mokelikeli oa phetiso, ho kenyeletsoa ho nkela sefe sebaka le ho tlosa litšila.
4. Hlalosa 'me, ha ho hlokahala, u nke sebaka sa mochine oa ho laola phetiso (TCM) kapa mochine oa taolo ea enjene (PCM) haeba bothata bo amana le bona.
5. Hlahloba le ho lokisa mathata afe kapa afe a phetiso ea ka hare a kang ho lutla, ho thibela khatello kapa mathata a 'mele oa valve.

Ho khothalletsoa hore u ikopanye le setsebi se tšoanelehang kapa lebenkele la ho lokisa likoloi bakeng sa tlhahlobo e nepahetseng haholoanyane le mosebetsi o nepahetseng oa ho lokisa.
