Khoutu ea phoso e bolela eng P0738?

Khoutu P0738 ke khoutu e tloaelehileng ea bothata ea OBD-II e bonts'ang bothata ka sensor ea lebelo la enjene ho Transmission Control Module (TCM). Sensor ena e lekola lebelo la enjene ebe e fetisetsa data ho mojule oa taolo ea powertrain (PCM), e sebelisang tlhahisoleseling ena ho fetola likere ka nepo. Ka tloaelo, lebelo la enjine le tlameha ho fapana ho latela lebelo le ntseng le eketseha la koloi ho netefatsa liphetoho tse thellang. Ha PCM e lemoha hore lebelo la enjene le fetoha ka potlako haholo kapa ha le fetohe ho hang, e hlahisa khoutu P0738. Khoutu ena e ka boela ea behoa haeba PCM e sa amohele letšoao ho tsoa ho sensor ea lebelo la enjene.

Khoutu ea P0738 ke khoutu e akaretsang ea OBD-II e sebetsang ho mefuta e fapaneng ea likoloi tse kenyelletsang Dodge, Chevrolet, Honda, Toyota, Hyundai, Jaguar le tse ling tse ngata. Le hoja khoutu e tloaelehile, mehato e tobileng ea ho e rarolla e ka 'na ea fapana ho itšetlehile ka koloi e itseng le tlhophiso ea eona.

Ka tloaelo, P0738 e amahanngoa le mathata a motlakase, hangata ho feta a mechine. Leha ho le joalo, mehato e nepahetseng ea ho hlahloba le ho lokisa e ka hloka tšebeletso ea setsebi 'me e ka fapana ho itšetlehile ka ho etsoa le mofuta oa koloi.

Lisosa tse ka khonehang

Lisosa tse ka bang teng tsa khoutu ea P0738 li kenyelletsa:

Matšoao ana a ka 'na a bontša mathata a phetisetso, ho kopanyelletsa le ho feto-fetoha ho hoholo, bothata ba enjene, le mathata a ponts'o ea lebelo la lebelo, a ka qetellang a baka moruo o mobe oa mafura.

Mokhoa oa ho fumana khoutu ea phoso P0738?

Ho hlahloba le ho lokisa khoutu P0738, ho kgothaletswa ho latela mehato ena:

1. Sebelisa sekena sa khoutu ea OBD-II ho fumana khoutu ea P0738 le ho hlahloba likhoutu tse ling tsa mathata.
2. Haeba ho fumanoa likhoutu tse ling, li shebe ka tatellano eo li hlahang ho eona sekeneng ebe u li rarolla ho qala ka ea pele.
3. Kamora ho hlahlojoa, hlakola likhoutu tsa mathata, qala koloi bocha, 'me u hlahlobe hore na khoutu ea P0738 e ntse e tsoela pele. Haeba khoutu e fela ka mor'a ho tsosolosa le ho qala bocha, e ka 'na eaba e bile bothata ba nakoana.
4. Haeba khoutu ea P0738 e phehella, hlahloba boemo ba mokelikeli oa phetiso le ho lutla hofe kapa hofe. Eketsa mokelikeli kamoo ho hlokahalang 'me u hlahlobe ka hloko hore na ha e lutle. Mokelikeli o lutlang o ka baka tšenyo e eketsehileng.
5. Haeba mokelikeli oa phetiso o silafetse, o nkele sebaka. Haeba mokelikeli o le litšila ka ho feteletseng, phetisetso e ka 'na ea hloka ho lokisoa kapa ho nkeloa sebaka.
6. Etsa tlhahlobo ea pono ea likarolo tsa motlakase. Tlosa lithapo tse senyehileng, likhokahano le li-fuse.
7. Lekola li-sensor tsa lebelo la tlhahiso, ho etsa bonnete ba hore sebaka sa bona sa matšoao le voltage ea litšupiso lia behoa leihlo.
8. Kamora ho lokisa khoutu ea P0738, hlakola likhoutu tsa mathata ebe o qala koloi bocha ho bona hore na khoutu e ea fela.

Ho bohlokoa hape ho nahana ka li-bulletin tsa litšebeletso tsa tekheniki (TSBs) bakeng sa koloi ea hau, kaha li ka ba le leseli mabapi le mathata a tsejoang le tharollo. Ho lokisa li-circuits le litsamaiso tsa lebelo la enjene ho ka hloka lisebelisoa tse khethehileng joalo ka sebali sa khoutu ea OBD, multimeter le lisebelisoa tsa wiring. Ela hloko mehato ea ts'ireletso 'me u netefatse bots'epehi ba betri le sistimi ea ho tjhaja pele o sebetsa ho likarolo tsa motlakase.
