P0641 - Sensor A Reference Voltage Circuit Open

Khoutu ea mathata P0641 e bolela'ng?

Khoutu ena ea Mathata a Tlhatlhobo (DTC) ke khoutu ea phetisetso e akaretsang, ho bolelang hore e sebetsa ho likoloi tse nang le thepa ea OBD-II. Le ha e le ka kakaretso, mehato e ikhethileng ea ho lokisa e ka fapana ho latela mofuta / mofuta.

Ha ke fumana khoutu e bolokiloeng ea P0641, ho bolela hore module ea powertrain control module (PCM) e fumane potoloho e bulehileng bakeng sa sensor e itseng; hlalositsoe ntlheng ena e le "A". Ha u fumana khoutu ea OBD-II, lentsoe "bula" le ka nkeloa sebaka ke "ha le eo".

Sensor eo ho buuoang ka eona hangata e amahanngoa le phetisetso ea othomathiki, nyeoe ea phetisetso, kapa e 'ngoe ea phapang. Khoutu ena e batla e lateloa ke khoutu ea sensor e ikhethileng haholoanyane. P0641 e eketsa hore potoloho e bulehile. Sheba mohloli o tšepahalang oa tlhaiso-leseling ea koloi (All Data DIY ke khetho e ntle) ho fumana sebaka (le ts'ebetso) ea sensor e amanang le koloi eo ho buuoang ka eona. Haeba P0641 e bolokiloe ka thoko, belaela hore ho etsahetse phoso ea lenaneo la PCM. Ho hlakile hore o tla hloka ho hlahloba le ho lokisa likhoutu tse ling tsa sensor pele o hlahloba le ho lokisa P0641, empa hlokomela "A" potoloho e bulehileng.

Tlhaloso ea motlakase (hangata volts tse hlano) e sebelisoa ho sensor e botsitsoeng ka potoloho e fetoloang (e nang le matla a motlakase). Hape ho lokela ho ba le lets'oao la fatše. Sensor e kanna ea ba le khanyetso e fapaneng kapa motlakase o fapaneng mme e koala potoloho e itseng. Ho hanyetsa ha sensor ho fokotseha ka khatello e ntseng e eketseha, mocheso kapa lebelo le ka tsela e fapaneng. Kaha khanyetso ea sensor e fetoha ka maemo, e fa PCM le lets'oao la motlakase oa ho kenya. Haeba lets'oao lena la ho kenya motlakase le sa amoheloe ke PCM, potoloho e nkuoa e bulehile mme P0641 e tla bolokoa.

Lebone la Sesebelisoa sa Ts'ebetso (MIL) le lona le ka bonesetsoa, ​​empa hlokomela hore likoloi tse ling li tla nka mekoloko e mengata ea ho khanna (ka ho se sebetse hantle) hore MIL e bule. Ka lebaka lena, o tlameha ho lumella PCM ho kenya mokhoa oa ho emisa pele o nahana hore ho lokisoa ho atlehile. Tlosa khoutu kamora ho e lokisa ebe o khanna joalo ka ha e le tloaelo. Haeba PCM e qala ho itokisa, tokiso e atlehile. Haeba khoutu e hlakotsoe, PCM e ke ke ea kena maemong a loketseng mme o tla tseba hore bothata bo ntse bo le teng.

Boima le matšoao

Boima ba P0641 e bolokiloeng bo ipapisitse le hore na potoloho ea kutlo e sebakeng se bulehileng. Pele o ka tseba hore na boima bo bokae, o hloka ho lekola likhoutu tse ling tse bolokiloeng.

Matšoao a khoutu ea P0641 a ka kenyelletsa:

• Ho se khone ho chencha phetiso lipakeng tsa mekhoa ea lipapali le moruo
• Lits'oants'o tsa phetoho ea likere
• Ho lieha (kapa ho hloka) ho bulela phetiso
• Phetiso ea phetiso ha e fetohe lipakeng tsa XNUMXWD le XNUMXWD
• Ho hloleha ha nyeoe ea phetisetso ho chencha ho tloha tlase ho ea holimo
• Ho hloka kenyelletso ea phapang e ka pele
• Ho haella ha boitlamo ba setsi se ka pele
• Speedometer / odometer e fosahetseng kapa e sa sebetseng

Lisosa tsa khoutu ea P0641

Lisosa tse ka bang teng tsa khoutu ena ea enjene li kenyelletsa:

• Potoloho e bulehileng le / kapa lihokelo
• Li-fuse tse senyehileng kapa tse phatlohileng le / kapa fuse
• Phoso ea matla a sistimi
• Sensor e mpe
• Mojule oa taolo ea enjine e sa sebetseng (ECM)
• Mohala oa ECM o butsoe kapa o khutsufalitsoe
• Potoloho e mpe ea motlakase ECM
• Sensor e khutsufalitsoe ho 5 volts See se bolela'ng?

Mekhoa ea ho hlahloba le ho lokisa

Ho fumana khoutu e bolokiloeng ea P0641, ke tla hloka phihlello ho sekena se hlahlojoang, digital volt / ohmmeter (DVOM), le mohloli o tšepahalang oa tlhaiso-leseling ea koloi (joalo ka All Data DIY). Oscilloscope ea letsoho le eona e ka ba molemo maemong a mang.

Sebelisa mohloli oa tlhaiso-leseling ea koloi ea hau ho tseba hore na sensor e sebakeng sefe le moo e sebetsang teng ha e amana le koloi ea hau. Lekola li-fuse tsa sistimi le li-fuse tse felletseng tsa mojaro. Li-fuse tse ka hlahang li tloaelehile ha potoloho e imetsoe habobebe, hangata e hloleha ha potoloho e laetsoe ka botlalo. Li-fuse tse phatlohileng li lokela ho nkeloa sebaka, ho hopoloa hore potoloho e khuts'oane e kanna ea ba sesosa sa fuse e phatlohileng.

Hlahloba ka mahlahahlaha lisebelisoa tsa wiring le lihokelo. Lokisa kapa kenya mohala o senyehileng kapa o chesitsoeng, likhokelo le likarolo ha ho hlokahala.

Eaba ke hokahanya sekena le socket ea tlhahlobo ea koloi mme ka fumana li-DTC tsohle tse bolokiloeng. Ke rata ho li ngola fatše hammoho le tlhaiso-leseling efe kapa efe e amanang le leqhoa, kaha tlhaiso-leseling ena e ka ba molemo haeba khoutu e ka ba e sa sebetseng. Kamora moo, ke ne ke ea pele ke hlakola khoutu mme ke leke koloi ho bona hore na e seta bocha hanghang.

Haeba li-fuse tsohle tsa sistimi li lokile 'me khoutu e hlophisoa bocha hanghang, sebelisa DVOM ho lekola lits'oants'o tsa motlakase le matšoao a fatše ho sensor e botsitsoeng. Ka kakaretso, o lokela ho lebella ho ba le li-volts tse hlano le sebaka se lumellanang sehokelong sa kutlo.

Haeba lipontšo tsa motlakase le tsa lefats'e li le teng sehokelong sa sensor, tsoela pele ho leka ho hanyetsa sensor le maemo a bots'epehi. Sebelisa mohloli oa tlhaiso-leseling ea koloi ho fumana lintlha tsa tlhahlobo le ho bapisa liphetho tsa hau tsa nnete le tsona. Lisebelisoa tse sa sebetsaneng le lintlha tsena li lokela ho nkeloa sebaka.

Tlosa balaoli bohle ba amanang le sistimi pele u leka ho hanyetsa le DVOM. Haeba ho se na lets'oao la phepelo ea motlakase ho sensor, hakolla balaoli bohle ba amanang le eona mme o sebelise DVOM ho leka ho hanela ha potoloho le ho tsoela pele lipakeng tsa senotlolo le PCM. Tlosa lipotoloho tse bulehileng kapa tse khuts'oane ha ho hlokahala. Haeba u sebelisa sesebelisoa sa motlakase se iphetang, sebelisa oscilloscope ho lekola data ka nako ea 'nete; ho ela hloko ka ho khetheha likhalase le lipotoloho tse bulehileng ka botlalo.
