P2120 Maƙallan Matsayin Matsayi / Canza C Circuit

Bayanan Bayani na OBD-II

Rashin aiki na sarkar firikwensin matsayi na bawul ɗin malam buɗe ido / feda / canza "D"

Mene ne wannan yake nufi?

Wannan Lambar Matsalar Bincike (DTC) lambar watsawa ce gaba ɗaya, wanda ke nufin ya shafi motocin OBD-II sanye take. Kodayake gabaɗaya a cikin yanayi, takamaiman matakan gyara na iya bambanta dangane da alama / ƙirar.

TPS (Matsakaicin Matsayi Sensor) wani ma'auni ne mai ƙarfi wanda aka ɗora akan maƙarƙashiya. Yana ƙayyade kusurwar maƙura. Lokacin da ma'aunin yana motsawa, TPS tana aika sigina zuwa PCM (Module Sarrafa Powertrain). Yawanci firikwensin waya 5: Nufin XNUMXV daga PCM zuwa TPS, ƙasa daga PCM zuwa TPS, da dawowar sigina daga TPS zuwa PCM.

TPS tana aika bayanin matsayin maƙura zuwa PCM akan wannan siginar waya. Lokacin da aka rufe maƙura, siginar tana kusan volts 45. Tare da WOT (Wide Open Throttle), ƙarfin siginar TPS yana kusanci 5 volts. Lokacin da PCM ta gano ƙarfin lantarki a waje da kewayon aiki na al'ada, an saita P2120. Harafin "D" yana nufin takamaiman da'irar, firikwensin, ko yanki na takamaiman da'ira.

NOTE: PCM ya san cewa duk wani babban canji a matsayin maƙura yana nufin canji mai dacewa a matsin lamba mai yawa (MAP). A kan wasu samfura, PCM za ta sa ido kan MAP da TPS don kwatantawa. Wannan yana nufin cewa idan PCM ya ga babban canji a cikin matsin lamba, yana tsammanin ganin canji mai dacewa a cikin matsi da yawa kuma akasin haka. Idan bai ga wannan canjin kwatankwacin ba, ana iya saita P2120. Wannan bai shafi dukkan samfura ba.

Idan kuna da damar yin amfani da kayan aikin sikirin, lura da ƙarfin TPS tare da KOEO (Injin Kashe Inji). Tare da rufe maƙura, ƙarfin lantarki ya zama kusan 45 V. Ya kamata a hankali ya tashi zuwa kusan 4.5-5 volts yayin da kuke tura maƙura. Wani lokaci, oscilloscope ne kawai zai iya kama siginar wutar lantarki na lokaci -lokaci na siginar TPS. Idan kun lura da gazawa a cikin wutar lantarki ta TPS, maye gurbin TPS.

NOTE. Wasu firikwensin TPS suna buƙatar daidaitawa mai kyau. Idan baku jin daɗin amfani da DVOM (Digital Volt Ohmmeter) don saita sabon TPS ɗin ku, mafi kyawun faren ku shine ɗaukar motar ku zuwa shago. Idan wutar lantarki ba 45V ba (+ ko -3V ko makamancin haka) tare da rufe ma'aunin, ko kuma idan karatun ya makale, cire haɗin haɗin TPS. Yin amfani da KOEO, bincika alamar 5V akan mai haɗawa da ƙasa mai kyau. Kuna iya gwada da'irar siginar ta hanyar matsar da waya mai fulawa tsakanin kewayen ƙasa na mai haɗin TPS da da'irar sigina. Idan karatun TPS akan kayan aikin dubawa yanzu ya karanta sifili, maye gurbin TPS. Koyaya, idan wannan bai canza karatun zuwa sifili ba, bincika buɗe ko gajere a cikin wayar siginar, kuma idan ba a sami komai ba, yi zargin PCM mara kyau. Idan magudi na kayan aikin TPS yana haifar da kowane canji a cikin aiki, to ana zargin TPS mara kyau.

• A halin yanzu babu batutuwa masu alaƙa a cikin dandalin mu. Sanya sabon taken akan dandalin yanzu.

Kuna buƙatar ƙarin taimako tare da lambar ku ta p2120?

Idan har yanzu kuna buƙatar taimako tare da DTC P2120, aika tambaya a cikin sharhin da ke ƙasa wannan labarin.

NOTE. An ba da wannan bayanin don dalilai na bayanai kawai. Ba a yi nufin amfani da shi azaman shawarar gyara ba kuma ba mu da alhakin duk wani mataki da za ku ɗauka a kan kowane abin hawa. Duk bayanan da ke wannan shafin ana kiyaye su ta haƙƙin mallaka.
