I-P2140 DTC Throttle / Pedal Position Sensor Voltage Correlation

I-P2140 DTC Throttle / Pedal Position Sensor Voltage Correlation

Idatha ye-OBD-II DTC

Inzwa / Isikhundla Sendawo Yokuphamba / E / F Shintsha i-Voltage Correlation

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Yokuhlola (i-DTC) yikhodi yokudlulisela ejwayelekile. Kubhekwa njengendawo yonke njengoba kusebenza kukho konke ukwakheka namamodeli ezimoto (ngo-1996 nangaphezulu), yize izinyathelo ezithile zokulungisa zingahluka kancane ngokuya ngemodeli.

Ikhodi yokungasebenzi kahle kwemoto I-P2140 Throttle / Pedal Position Sensor / E / F Shintsha i-Voltage Correlation Kusho inkinga ngamandla we-valve mpintsha wokuvula nokuvala kahle.

Ngawo-1990, abakhiqizi bezimoto baqala ukwethula ubuchwepheshe bokulawula i-throttle "Drive by wire" yonke indawo. Inhloso yayo wukuhlinzeka ngokulawula okuthe xaxa kokungcoliswa komoya, ukonga kukaphethiloli, ukulawulwa kokudonsa kanye nokuzinza, i-cruise control kanye nokusabela kokudluliswa kwemishini.

Ngaphambi kwalokhu, i-valve mpintsha yemoto yayilawulwa ngentambo elula enokuxhumeka okuqondile phakathi kwephethiloli yegesi ne-valve mpintsha. I-Throttle Position Sensor (TPS) itholakala maqondana ne-throttle rod uxhumano emzimbeni we-throttle. I-TPS iguqula ukunyakaza kokuma nempo ibe yisiginali yamandla bese iyithumela kukhompyutha yokulawula injini, esebenzisa isiginali ye-AC voltage ukwakha isu lokulawula injini.

Ubuchwepheshe obusha be- "electronic throttle valve" technology buqukethe i-accelerator pedal position sensor, umzimba we-throttle olawulwa nge-elekthronikhi ophelele nenjini yangaphakathi, izinzwa zesimo se-throttle ezimbili ezihlanganisiwe zama-coefficients wokuhlanganisa nekhompyutha yokuphatha injini.

Yize ikhodi inezinhlaka ezifanayo, ibizwa ngamagama ahlukile kweminye imikhiqizo, enjenge “Throttle Position Sensor Circuit Range / Performance” ku-Infiniti noma “Electronic Throttle Control Failure Power Management” kwaHyundai.

Uma ucindezela i-pedator ye-accelerator, ucindezela inzwa ekhombisa inani lokuvula elifunekayo, elithunyelwa kukhompyutha yokulawula injini. Ukuphendula, ikhompiyutha ithumela i-voltage emotweni ukuvula i-mpintsha. Izinzwa ezimbili zempumuzo ezakhelwe emzimbeni we-mpintsha ziguqula inani lokuvula lokuqina libe yisiginali yamandla we-voltage kwikhompyutha.

Isithombe Somzimba We-Throttle, Inzwa Yesimo Se-Throttle (TPS) - ingxenye emnyama ngezansi kwesokudla:

Ikhompyutha ibheka isilinganiso sazo zombili izintambo. Lapho zombili izintambo zifana, uhlelo lusebenza ngokujwayelekile. Lapho ziphambuka ngemizuzwana emibili, ikhodi i-P2140 isethiwe, ekhombisa ukungasebenzi kahle kwenye indawo kuhlelo. Amanye amakhodi wephutha angafakwa kule khodi ukuze kuqhutshekwe nokuhlonza inkinga. Iqiniso ukuthi ukulahlekelwa ukulawula kwe-throttle kungaba yingozi.

Nasi isithombe se-accelerator pedal ngenzwa ne-wiring enamathiselwe:

QAPHELA. Le DTC P2140 ngokuyisisekelo iyefana ne-P2135, P2136, P2137, P2138 ne-P2139, izinyathelo zokuxilonga zizolingana kuwo wonke amakhodi.

izimpawu

Izimpawu zekhodi P2140 zingasukela ekumiseni kuze kube sekumeni, awekho amandla nhlobo, akukho ukusheshisa, ukulahleka kwamandla kungazelelwe ngesivinini sokuhamba, noma ukubambelela empini ku-rpm yamanje. Ngaphezu kwalokho, ukukhanya kwenjini yokuhlola kuzovela bese kuzobekwa ikhodi.

Izimbangela Ezingenzeka ze-DTC P2140

• Kokuhlangenwe nakho kwami, isixhumi sezintambo noma umsila wengulube emzimbeni wempintsha unikeza izinkinga ngendlela yokuxhuma okungalungile. Amatheminali abesifazane kwi-pigtail ayonakalisiwe noma akhishwe kusixhumi.
• Ukujikeleza okuncane okungenzeka kocingo olungenalutho kuya ku-pigtail phansi.
• Isembozo esiphezulu somzimba wokukhubazeka sikhubazekile, okuphazamisa ukujikeleza okulungile kwamagiya.
• Umzimba we-elekthronikhi unephutha emzimbeni.
• Inzwa yokuhamba ye-accelerator engaphelele noma i-wiring.
• Ikhompyutha elawula injini ayisebenzi.
• Izinzwa ze-TPS azihlangani imizuzwana embalwa futhi ikhompyutha idinga ukujikeleza ngesigaba sokufunda kabusha ukuze ibuyise impendulo esebenzayo yomzimba, noma ikhompyutha idinga ukwenziwa kabusha ngumthengisi.

Izinyathelo zokuxilonga / zokulungisa

Amanothi ambalwa mayelana ne-throttle elawulwa ngogesi. Lolu hlelo luzwela ngendlela emangalisayo futhi lusengozini yokulimala kunanoma iyiphi enye isistimu. Yiphathe kanye nezingxenye zayo ngokucophelela okukhulu. Iconsi elilodwa noma ukuphathwa kabi futhi lokho kungumlando.

Ngokungezelela ku-accelerator pedal sensor, ezinye izingxenye zitholakala emzimbeni we-throttle. Lapho uhlolwa, uzobona isembozo sepulasitiki esicaba ngaphezulu komzimba wempintsha. Iqukethe amagiya okushukumisa i-valve mpintsha. Imoto inamagiya amancane ensimbi aphuma ezindlini ezingaphansi kwesembozo. Ishayela igiya elikhulu "lepulasitiki" elinamathele emzimbeni mpintsha.

Iphini eligxilisa futhi lisekele igiya lingena emzimbeni wempintsha, bese kuthi iphini eliphezulu lingene kukhava "omncane" wepulasitiki. Uma ikhava ikhubazeka nganoma iyiphi indlela, igiya lizohluleka, elidinga ukushintshwa komzimba okuphelele.

• Into yokuqala okufanele ukwenze ukungena ku-inthanethi bese uthola i-TSB (Service Bulletin) yemoto yakho ehambisana nekhodi. Lawa ma-TSB angumphumela wezikhalazo zamakhasimende noma izinkinga ezihlonziwe kanye nenqubo yokulungisa enconyiwe yomkhiqizi.
• Bheka ku-inthanethi noma kumanuwali yakho yesevisi ukuthola inqubo engaphinde yokufunda kabusha ukuqala kabusha ikhompyutha yakho. Isibonelo, ku-Nissan, vula ukuthungela bese ulinda imizuzwana emi-3. Ngemizuzwana emi-5 elandelayo, cindezela bese ukhipha isinyathelo kaningi. Linda imizuzwana engu-5, cindezela bese ubamba isinyathelo ngamasekhondi ayi-7. Lapho ilambu lenjini yokuhlola liqala ukukhanyisa, dedela iphedali. Linda imizuzwana engu-10, cindezela i-pedal futhi imizuzwana eyi-10 bese uyadedela. Cisha ukuthungela.
• Susa isixhumi sikagesi emzimbeni mpintsha. Ihlole ngokucophelela ngamatheminali wokukhipha alahlekile noma agobile. Bheka ukugqwala. Susa noma imuphi umkhondo wokugqwala nge-screwdriver esincane esikhwameni. Faka inani elincane lamafutha kagesi ezikhumulweni bese uxhuma kabusha.
• Uma isixhumi sokugcina sigobile noma izikhonkwane ezingekho, ungathenga i-pigtail entsha ezindaweni eziningi zezitolo noma kumthengisi wakho.
• Hlola isembozo esiphezulu somzimba wokugoqa ukuthola imifantu noma ukusonteka. Uma kukhona, shayela umthengisi ubuze ukuthi ngabe bathengisa kuphela ikhava ephezulu. Uma kungenjalo, shintsha umzimba wempintsha.
• Sebenzisa i-voltmeter ukuhlola i-accelerator pedal sensor. Kuzoba nama-volts ama-5 okusetshenziswa kuwo, futhi kuzoba nesiginali eshintshayo eduze kwayo. Vula ukhiye bese ucindezela kancane iphedali. Amandla kagesi kufanele akhule kancane ukusuka ku-5 kuye ku-5.0. Faka esikhundleni saso uma i-voltage ikhuphuka kakhulu noma kungekho voltage ocingweni lwesiginali.
• Sesha i-Intanethi ukuthola amatheminali ocingo emzimbeni wemoto yakho. Hlola isixhumi somzimba mpintsha ukuthola amandla emotweni yokumpintsha. Cela umsizi akhanyise ukhiye bese ecindezela kancane iphedali. Uma engekho amandla, ikhompyutha inephutha. Umzimba we-throttle awunasici uma unamandla.

Amanye ama-DTC ahlobene ne-throttle: P0068, P0120, P0121, P0122, P0123, P0124, P0510 nabanye.

QAPHELA. Lolu lwazi lunikezwa ngenhloso yokwaziswa kuphela. Akuhloselwe ukuthi isetshenziswe njengesincomo sokulungisa futhi asinacala nganoma yisiphi isenzo osithathayo kunoma iyiphi imoto. Yonke imininingwane ekulesi siza ivikelwe yi-copyright.
