U ka hlahloba sensor ea PMH joang?

Sensor Setsi sa bafu se holimo (TDC) ea koloi ea hau e etsa qeto ea boemo lipistone... E ntan'o fetisetsa tlhahisoleseding ena ho enjene ea ECU, e ka khonang ho tseba hore na ente ea peterole e hlokahalang bakeng sa lebelo. Haeba sensor ea TDC e sa sebetse, u tla ba le eona mathata a ho qala... Mona ke mokhoa oa ho hlahloba sensor ea PMH.

Lintho tse bonahalang:

• E phunyeletsang
• Chiffon
• Lisebelisoa
• Voltmeter
• oscilloscope
• Multimeter

🔎 Mohato oa 1: Sheba sensor ea TDC ka mahlo.

Ho leka sensor ea TDC, o tlameha ho qala ho e fumana. Sensor ea TDC, eo hape e bitsoang sensor ea crankshaft, e fumaneha ka har'a crankshaft le flywheel ka tlase ho enjene. Tlosa "sensor retaining screw" 'me u hakolle harness lipakeng tsa sensor ea TDC le enjene ea ECU.

Ha re qale ka tlhahlobo e bonolo ea pono ea sensor ea TDC:

• Etsa bonnete ba hore ha e koalehe;
• Etsa bonnete ba hore lekhalo la moea ha lea senyeha;
• Sheba marang-rang pakeng tsa sensor ea TDC le ECU ea enjene.

U ka boela ua nka monyetla oa ho hlahloba kutlo ea hau ea PMH u sebelisa sesupa-tsela. Ke mofuta oa teko ea pele, e ka u joetsa hore na sensor ea sebetsa. Ehlile, sensor ea TDC e inductive e na le matla a khoheli a bonang lintho tsa tšepe.

• Haeba sensor e hula leboea, e sebetsa;
• Haeba a hula boroa, ke HS!

Tlhokomeliso, tlhahlobo ena ha e sebetse ka kutlo e sebetsang ea PHM, e tsejoang hape e le Hall effect. Sensor e sebetsang ea TDC ha e na lebala la motlakase hobane ke ea elektronike ka ho feletseng. E fumanoa, haholo-holo, lienjiniking tsa morao-rao.

💧 Mohato oa 2. Hloekisa sensor ea TDC.

Bakeng sa ts'ebetso e felletseng, sensor ea TDC ha ea lokela ho silafala. Mona ke mokhoa oa ho hloekisa sensor ea TDC pele u e hlahloba:

• Fafatsa WD 40 kapa mafura afe kapa afe 'meleng oa kutlo;
• Hlakola ka bonolo ka lesela le hloekileng ho fihlela litšila tsohle le mafome li tlosoa.

⚡ Mohato oa 3. Sheba letšoao la motlakase le ho hanyetsa ha sensor ea TDC.

Ebe u sheba lets'oao la motlakase le khanyetso ea sensor ea hau ea TDC. Leha ho le joalo, ela hloko mofuta oa sensor eo ho buuoang ka eona: haeba u na le sensor e sebetsang ea TDC, ha u na khanyetso ea tlhahlobo. U ka sheba feela lets'oao ho tsoa ho sensor ea TDC ea Hall effect.

Sebelisa ohmmeter kapa multimeter ho lekola sensor ea TDC ea inductive. Hokela multimeter ho tlhahiso ea sensor ea TDC 'me u hlahlobe boleng bo bontšitsoeng. E itšetlehile ka moetsi oa koloi. Leha ho le joalo, e tla ba pakeng tsa 250 le 1000 ohms. Haeba e le zero, ho na le potoloho e khuts'oane kae-kae.

Ebe u hlahloba letšoao la motlakase. Sebelisa oscilloscope ho leka sensor ea TDC ea Hall effect e nang le lithapo tse 3 (tse ntle, tse mpe le tse nang le letšoao). E ile ea bonahala e le khutlonnetsepa. Bakeng sa sensor e sebetsang ea TDC, oscilloscope ke sinusoidal.

Sheba letšoao la tlhahiso ka voltmeter. Tlosa sehokelo sa sensor ea TDC ebe u hokela voltmeter ho tsoa ho AC. Sephetho sa sensor e ntle ea TDC se pakeng tsa 250 mV le 1 Volt.

👨‍🔧 Mohato oa 4. Etsa tlhahlobo ea elektronike.

Leha ho le joalo, mokhoa o ka tšeptjoang ka ho fetisisa le o ka tšeptjoang oa ho hlahloba sensor ea TDC, tlhahlobo ea elektronike, ha e fumanehe ho bohle. Ehlile, joale o lokela ho ba le nyeoe ea tlhahlobo le software e tsamaeang le autodiagnostic. Leha ho le joalo, sesebelisoa sena se turu haholo 'me hangata ke tsa mak'henike a litsebi feela. Empa haeba u le mak'henike, ha ho letho le u thibelang ho tsetela.

Software ea ho hlahloba e khutlisa khoutu ea phoso e bontšang mofuta oa bothata ka sensor ea TDC (mohlala, ha ho na pontšo). U ka boela ua tsamaisa li-diagnostics ha u qala ho shebella, ka curve e hlokometsoeng, ts'ebetso e nepahetseng ea sensor.

🔧 Mohato oa 5: Kopanya sensor ea TDC

Kamora ho hlahloba sensor ea TDC, o tlameha ho e kopanya hape. Kenya sensor flat, tiisa screw fixing. Kopanya lehare la sensor hape, ebe o qala koloi ho netefatsa hore e sebetsa hantle.

Ke eona, u tseba ho leka sensor ea PMH! Empa, joalo ka ha u se u ntse u utloisisa, tlhahlobo e ntle ka ho fetisisa e ntse e le tlhahlobo ea elektronike, mekhoa ea eona e u lumellang ho fumana hantle hore na bothata ke bofe. Ho hlahloba le nka sebaka sa sensor ea PMHkahoo bapisa likarache tse pota-potileng 'me u tšepe koloi ea hau ho batho ba molemo!
