Ikhodi Yenkinga ye-OBD-II - P0121 Incazelo Yobuchwepheshe

I-P0121 - Inzwa Yesimo Se-Throttle/Shintsha Ibanga Lesifunda/Inkinga Yokusebenza.

I-DTC P0121 yenzeka lapho imojula yokulawula injini (ECU, ECM noma PCM) ithola inzwa engalungile ye-throttle position (TPS - Throttle Position Sensor), ebizwa nangokuthi i-potentiometer, ethumela amanani angalungile ngokuvumelana nemithethonqubo.

Isho ukuthini ikhodi yenkinga P0121?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezihlomele i-OBD-II. Yize kuvamile emvelweni, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli.

Inzwa ye-throttle position iyi-potentiometer ekala inani lokuvuleka kwe-throttle. Njengoba i-throttle ivuliwe, ukufundwa (kulinganiswa ngama-volts) kuyanda.

Imodyuli yokulawula i-powertrain (PCM) inikezela ngesiginali engu-5V yesikhombi ku-Throttle Position Sensor (TPS) futhi imvamisa futhi iphansi. Isilinganiso esijwayelekile: idle = 5V; mpintsha ogcwele = 4.5 volts. Uma i-PCM ithola ukuthi i-throttle angle inkulu noma incane kunalokho okufanele ibe yi-RPM ethile, izosetha le khodi.

Izimpawu ezingaba khona

Izimpawu zekhodi yenkinga ye-P0121 zingafaka:

  • Ilambu Lesikhombi Esingasebenzi kahle (MIL) esikhanyisiwe (Bheka i-Light Light noma i-Engine Service Ngokushesha)
  • Ukukhubeka okungatheni lapho kusheshiswa noma kwehliswa
  • Ukuqhuma intuthu emnyama lapho kusheshiswa
  • Ayiqali
  • Vula isibani sesexwayiso senjini esihambisanayo.
  • Ukungasebenzi kahle kwenjini, okungaholela ekushayweni kabi.
  • Izinkinga ngokusheshisa ukuqondisa.
  • Izinkinga ngokuqalisa injini.
  • Ukwenyuka kokusetshenziswa kukaphethiloli.

Nokho, lezi zimpawu zingase futhi zivele zihlangene namanye amakhodi amaphutha.

Izimbangela zephutha P0121

Inzwa ye-throttle position yenza umsebenzi wokuqapha nokunquma i-angle yokuvula yale damper. Ulwazi olurekhodiwe lube seluthunyelwa kuyunithi yokulawula injini, eyisebenzisela ukubala inani likaphethiloli elidingekayo ukuze lijovwe kusekethe ukuze kuzuzwe ukusha okuphelele. Uma imojula yokulawula injini ithola indawo eshintshashintshayo ye-throttle ngenxa yenzwa yendawo enephutha, i-DTC P0121 izosethwa ngokuzenzakalelayo.

Ikhodi ye-P0121 ingasho ukuthi umcimbi owodwa noma eminingi yenzekile:

  • Ukungasebenzi kahle kwenzwa yokuma kwe-Throttle.
  • Iphutha lezintambo ngenxa yocingo olungenalutho noma isifunda esifushane.
  • Inkinga yezintambo zenzwa yokuma kwe-Throttle.
  • Ukuba khona komswakama noma ukungena kwangaphandle okuthinta ukusebenza kwesistimu kagesi.
  • Izixhumi ezinephutha.
  • Ukungasebenzi kahle kwemojuli yokulawula injini, ukuthumela amakhodi angalungile.
  • I-TPS inesikhashana esivulekile noma isifunda esifushane sangaphakathi.
  • I-harness iyahlikihla, ibangela ukujikeleza okuvulekile noma okufushane ku-wiring.
  • Ukuxhumeka okungalungile ku-TPS
  • I-PCM engalungile (mancane amathuba okuthi)
  • Amanzi noma ukugqwala kusixhumi noma inzwa

Izixazululo ezingenzeka

1. Uma ukwazi ukufinyelela ithuluzi lokuskena, bona ukuthi yini okufundwayo okungasebenzi futhi okubanzi okuvulekile kwe-TPS kwe-TPS. Qiniseka ukuthi basondelene nemininingwane eshiwo ngenhla. Uma kungenjalo, shintsha i-TPS bese uqala kabusha.

2. Bheka isekhethi esivulekile noma esifushane esisesiginali ye-TPS. Awukwazi ukusebenzisa ithuluzi lokuskena kulokhu. Uzodinga i-oscillator. Lokhu kungenxa yokuthi amathuluzi okuskena athatha amasampula wokufundwa okuningi okuhlukile kulayini owodwa noma emibili yedatha futhi angalahlekelwa ukuphuma okuphakathi. Xhuma i-oscilloscope futhi ugcine isignali. Kufanele iphakame futhi iwele ngaphandle kwezihibe, ngaphandle kokuphuma noma ukuphuma.

3. Uma kungatholakali nkinga, yenza isivivinyo sokuzulazula. Yenza lokhu ngokunyakazisa isixhumi ne-harness ngenkathi ubheka iphethini. Uphuma uphume? Uma kunjalo, shintsha i-TPS bese uqala kabusha.

4. Uma ungenaso isignali ye-TPS, hlola ireferensi engu-5V kusixhumi. Uma ukhona, hlola isifunda somhlabathi ukuthola isifunda esivulekile noma esifushane.

5. Qiniseka ukuthi isekhethi yesiginali ayiyona i-12V. Akufanele ibe namandla kagesi ebhethri. Uma kunjalo, landela isifunda okwesikhashana ukuya ku-voltage nokulungisa.

6. Funa amanzi kusixhumi bese ushintsha i-TPS uma kudingeka.

Enye inzwa ye-TPS nama-DTC wesekethe: P0120, P0122, P0123, P0124

Amathiphu Wokulungisa

Ngemva kokuba imoto isiyiswe endaweni yokusebenzela, umakhenikha ngokuvamile uzokwenza lezi zinyathelo ezilandelayo ukuze ahlonze kahle inkinga:

  • Skena amakhodi ephutha ngesikena esifanelekile se-OBC-II. Uma lokhu sekwenziwe futhi ngemva kokuba amakhodi esethiwe kabusha, sizoqhubeka nokuhlola ukushayela emgwaqeni ukuze sibone ukuthi amakhodi aphinde avele yini.
  • Ihlola inzwa yokuma kwe-throttle.
  • Ukuhlolwa kwezingxenye zesistimu yekhebula.
  • Ukuhlolwa kwe-throttle valve.
  • Ukulinganisa ukumelana kwenzwa ngensimbi efanelekile.
  • Ukuhlolwa kwezixhumi.

Ukushintshwa okusheshayo kwenzwa ye-throttle akunconywa, njengoba imbangela ye-P0121 DTC ingase ilele kwenye into, njengesifunda esifushane noma izixhumi ezimbi.

Ngokuvamile, ukulungiswa okuvame ukuhlanza le khodi kungokulandelayo:

  • Lungisa noma shintsha inzwa yokuma kwe-throttle.
  • Ukulungisa noma ukushintshwa kwezixhumi.
  • Ukulungisa noma ukushintshwa kwezakhi zezintambo zikagesi ezinephutha.

Ukushayela ngekhodi yephutha engu-P0121 akunconywa, njengoba lokhu kungase kuthinte kabi ukuzinza kwemoto emgwaqeni. Ngalesi sizathu, kufanele uhambise imoto yakho endaweni yokusebenzela ngokushesha okukhulu. Uma kubhekwa inkimbinkimbi yokuhlola okwenziwayo, inketho ye-DIY egaraji lasekhaya ngeshwa ayinakwenzeka.

Kunzima ukulinganisa izindleko ezizayo, ngoba okuningi kuncike emiphumeleni yokuxilongwa okwenziwa umakhenikha. Imvamisa, izindleko zokulungisa i-throttle body endaweni yokusebenzela zingadlula ama-euro angama-300.
