Bohareng Shaft Speed ​​Sensor C Potoloho

See se bolela eng?

Ena ke Kh'outu ea Tlhatlhobo ea generic (DTC) mme e sebelisoa hangata ho likoloi tsa OBD-II tse nang le phetiso e ikemetseng. Sena se ka kenyelletsa empa ha se felle feela ho Mazda, Toyota, Chrysler, Ford, VW, Dodge, Jeep, Mercedes, Lexus, Chevrolet, jj.

Leha e le kakaretso, mehato e nepahetseng ea ho lokisa e ka fapana ho latela selemo sa mohlala, sebopeho, phetisetso le phetisetso ea phetisetso.

Countershaft, eo hape e tsejoang ka hore ke countershaft, e thusa ho aba matla a potolohang ho tloha ho drive drive ho isa shaft e hlahisang kahare ho phetisetso. Lebelo la countershaft le latela hore na u ho gear efe. Phetisong ea matsoho, sena se laeloa ke sebali sa likhetho, ka hona ha ho na lebaka la ho laola lebelo la lipakeng tsa theko.

Ka lehlakoreng le leng, phetisong ea othomathike, haeba u le ka har'a "D" mode ea ho khanna, lisebelisoa tseo u leng ho tsona li khethoa ke TCM (module ea taolo ea phetisetso) e sebelisa lisebelisoa tse ngata tsa kutlo tse tlatsetsang liphetohong tse boreleli le tse sebetsang. E 'ngoe ea li-sensor tse kenyellelitsoeng mona ke sensor ea lebelo le mahareng la shaft. TCM e hloka kenyelletso e khethehileng ho thusa ho khetholla le ho lokisa khatello ea haeteroliki, lintlha tsa phetoho le lipaterone. Boiphihlelo ba ho hloaea mefuta e meng ea li-sensor tsa lebelo (mohlala: VSS (sensor ea senotlolo sa koloi), ESS (enjene ea lebelo la enjene), jj.) E tla u thusa ka sena, hobane li-sensor tse ngata tsa lebelo li tšoana ka moralo.

ECM (Engine Control Module) ka kopanelo le TCM (Transmission Control Module) e ka kenya tšebetsong P2749 le likhoutu tse amanang le eona (P2750, P2751, P2752) ha ba lekola ho se sebetse hantle ho sensor ea lebelo la shaft kapa lipotoloho. Nako le nako, ha sensor e hloleha, TCM e sebelisa li-sensors tse ling tsa lebelo phetisong ebe e beha khatello ea "backup" ea hydraulic ho boloka phetiso ea othomathike e sebetsa, empa sena se ka fapana haholo lipakeng tsa baetsi.

Khoutu P2749 Intermediate Shaft C Speed ​​Sensor Circuit e behiloe ke ECM (Engine Control Module) le / kapa TCM (Transmission Control Module) ha ba shebile ho se sebetse hantle ho C speed sensor kapa potoloho ea eona. Sheba buka ea hau ea ho lokisa likoloi ho fumana hore na ke karolo efe ea ketane ea "C" e loketseng ts'ebeliso ea hau e ikhethang.

HLOKOMELA. Ngola likhoutu life kapa life tse sebetsang lits'ebetsong tse ling haeba ho bonesitsoe mabone a mangata a tlhokomeliso (mohlala, taolo ea likhohlopo, ABS, VSC, jj.).

Setšoantšo sa sensor ea lebelo la phetiso:

Boima ba DTC ee ke bofe?

Nka re phoso ena e matla haholo. Joalokaha ho boletsoe pejana, phetiso ea hau ea othomathiki e kanna ea sebetsa hantle. Leha ho le joalo, e ka boela ea e-ba sesupo haeba ho na le bothata bo le bong kapa ho feta. Leano le molemohali ke ho hlahloba bothata bofe kapa bofe ba phetiso kapele kamoo ho ka khonehang.

A mang a matšoao a khoutu ke afe?

Matšoao a khoutu ea mathata a P2749 a ka kenyelletsa:

• Ho fetoha ka thata ha gear
• Lipontšo tse ngata tsa dashboard lia bonesa
• Ho sebetsana hampe
• Lebelo le sa tsitsang la enjene

A mang a mabaka a tloaelehileng a khoutu ke afe?

Mabaka a khoutu ena ea enjene ea P2749 a ka kenyelletsa:

• Semela se lebelo se senyehileng kapa se senyehileng sa shaft
• Phoso ea motlakase mohala o pakeng tsa senotlolo sa lebelo le li-module tse sebelisitsoeng
• Mathata a kahare le ECM le / kapa TCM
• Lisebelisoa tse ling tse amanang le tsona / li-solenoids li senyehile kapa ha li na thuso (mohlala: input shaft speed sensor, output shaft sensor, shift solenoid, jj.)
• Mokelikeli oa tšoaetso o litšila kapa o tlaase o ikemetseng (ATF)

Ke mehato efe e meng ea ho rarolla bothata ba P2749?

Mohato oa mantlha # 1

Haeba u etsa lipatlisiso ka khoutu ena, ke tla nka hore u se u ntse u hlahlobile boemo ba mokelikeli oa phetisetso. Haeba ho se joalo, qala ka sena. Etsa bonnete ba hore mokelikeli o hloekile ebile o tletse hantle. Hang ha mokelikeli o se o lokile, o hloka ho fumana senotlolo sa lebelo la countershaft. Hangata li-sensor tsena li kentsoe ka kotloloho matlong a phetisetso.

U ka fihlella sensor ka tlasa hood, hona ho ka kenyelletsa ho tlosa karolo e ngoe e joalo ka e hloekisang moea le lebokose, libakete tse fapaneng, mehala, jj ho fumana phihlello. Etsa bonnete ba hore senotlolo le sehokedi se amanang le tsona li maemong a matle ebile li hokahane ka botlalo.

KELETSO: Ho chesoa ha ATF (motlakase oa phetisetso ea othomathike) e nkha joaloka mokelikeli o mocha oa hlokahala, kahoo u se ke oa tšaba ho etsa ts'ebeletso e felletseng ea phetisetso ka li-filters, gaskets le fluid.

Mohato oa mantlha # 2

Sensor ea lebelo le fumanehang habonolo e lokela ho tlosoa le ho hloekisoa. Ha ho hlokahale letho, 'me haeba u fumana hore sensor e litšila haholo ka mor'a ho tlosoa, u ka hlatsoa mathata a hau ka tsela ea sebele. Sebelisa hloekiso ea mariki le rag ho boloka sensor e hloekile. Litšila le / kapa litelu li ka ama ho baloa ha lisele, kahoo etsa bonnete ba hore sensor ea hau e hloekile!

HLOKOMELA. Letšoao lefe kapa lefe la khohlano ho sensor le ka bonts'a sebaka se sa lekanang lipakeng tsa lesale la senoko le sensor. Mohlomong sensor e fosahetse mme joale e se e le lesale. Haeba sensor e ncha e sa hloekise selikalikoe, sheba mekhoa ea ho etsa thepa ho lokisa lekhalo la sensor / reactor.

Mohato oa mantlha # 3

Sheba sensor le potoloho ea eona. Ho leka sensor ka boeona, o tla hloka ho sebelisa multimeter le litlhaloso tse ikhethileng tsa moetsi le ho lekanya litekanyetso tse fapaneng tsa motlakase lipakeng tsa lithakhisa tsa sensor. Leqheka le leng le letle ke ho etsa liteko tsena ho tsoa lithapong tse tšoanang, empa ho lithapo tse nepahetseng ho sehokelo sa ECM kapa TCM. Sena se tla hlahloba botšepehi ba lebanta la setulo le sebelisoang hammoho le sensor.
