I-P0470 - I-OBD-II Ikhodi Yenkinga Incazelo Yobuchwepheshe

Khipha inzwa yengcindezi yegesi

Isho ukuthini ikhodi yephutha P0470?

Le khodi evamile yokuxilonga iyasebenza ezinhlobonhlobo zezimoto, okuhlanganisa iFord, Mercedes kanye neNissan, enezinhlobo ezahlukene zezinjini, okuhlanganisa uphethiloli nodizili, kusukela ngo-2005. Ihlobene nokucindezelwa kwegesi yokukhipha futhi ingase ibonise inkinga kagesi noma yemishini. Kwesinye isikhathi ingahambisana nekhodi ye-P0471, ehluka ngesikhathi kanye nemvelo yokwehluleka kwenzwa yokucindezela kokukhipha. Izinyathelo zokulungisa zincike kumkhiqizi, uhlobo lukaphethiloli nombala wentambo.

Ikhodi yenkinga P0470 ijwayelekile kuzo zonke izinhlobo zezimoto namamodeli ahlukahlukene. Ibonisa inkinga ngenzwa yokucindezela kwegesi ephumayo futhi ingase ibe ngenxa yezinkinga zikagesi noma zemishini. Kwesinye isikhathi ihambisana nekhodi ye-P0471, ehluka ngesikhathi senkinga kanye nemvelo yokuhluleka kwenzwa. Izinyathelo zokulungisa zingahluka kuye ngomkhiqizi, uhlobo lukaphethiloli, nombala wentambo.

Inzwa ye-Exhaust Back Pressure (EBP) idlala indima ebalulekile ekulinganiseni umfutho wegesi ephumayo futhi ivumela ukulawulwa kwe-Exhaust Back Pressure Regulator (EPR) ngomyalo ovela ku-Engine Control Module (ECM).

Ukulinganisa Okujwayelekile Kokucindezela:

Amakhodi Enkinga Yenzwa Yokukhipha Ingcindezi Ehlobene:

  • I-P0471 Exhaust Gas Pressure Sensor “A” Ibanga Lesifunda/Ukusebenza
  • I-P0472 Izinga lesignali eliphansi kumjikelezo wenzwa yokucindezela kwegesi ephumayo “A”
  • I-P0473 Exhaust gas pressure sensor “A” high circuit
  • I-P0474 Exhaust gas pressure sensor “A” ukungasebenzi kahle kwesekethe

Izizathu ezingenzeka

Le khodi ye-P0470 ingase ivele ngenxa yezizathu ezilandelayo:

  1. Kukhona ukuvaleka kushubhu phakathi kwe-multifold exhaust kanye nenzwa yokucindezela.
  2. Izinkinga nge-EGR noma isistimu yokungenisa umoya, okuhlanganisa ukuvuza komoya okushaja.
  3. Inzwa yokucindezela kwegesi ephumayo enesici.
  4. Okungavamile: Ukulimala okungenzeka ku-Powertrain Control Module (PCM), nakuba kungenakwenzeka.
  5. Kukhona ukuvaleka kupayipi elixhuma inzwa yokucindezela ku-multifold exhaust.
  6. I-exhaust gas recirculation system ayisebenzi kahle, okungaholela ekuvuzeni komoya.
  7. Inzwa ye-backpressure sensor enephutha.
  8. Izinkinga nge-exhaust backpressure wiring harness, njengokuvula noma amasekhethi amafushane.
  9. Uxhumano lukagesi olungeluhle kusekethe yenzwa yokucindezela kwe-backpressure exhaust.

Yiziphi izimpawu zekhodi yephutha? P0470?

Izimpawu zekhodi ye-P0470 zifaka:

  1. I-Malfunction Indicator Light (MIL), eyaziwa nangokuthi isibani senjini yokuhlola, iyakhanya.
  2. Ukubukeka okungenzeka kwesibani esithi "Hlola Injini" kuphaneli yokulawula enekhodi enephutha egcinwe kumemori ye-ECM.
  3. Ukuphelelwa amandla enjini.
  4. Amathuba okukhubaza isilawuli sokucindezela igesi ephumayo.

Ikhodi ye-P0470 ithathwa njengebucayi ngoba ingaphazamisa ukuphatha nokusebenza kwemoto. Kodwa ingaqedwa kalula ngokushintsha inzwa yokucindezela kwegesi engasebenzi kahle.

Izimpawu zekhodi ye-P0470 nazo zingabandakanya:

  1. Isibani senjini yokuhlola sihlala sikhanya.
  2. Ukuntuleka kwamandla.
  3. Ukwehluleka ukukhiqiza kabusha isihlungi se-diesel particulate, okungase kuphumele ekuhlulekeni kokuqala kwenjini.

Indlela yokuxilonga ikhodi yephutha P0470?

Indlela enhle yokuqala ukuhlonza ikhodi ye-P0470 ukuhlola i-Technical Service Bulletin (TSB) ukuze uthole uhlobo lwemoto yakho. Umkhiqizi angase anikeze isibuyekezo sesofthiwe (i-firmware) ukuze i-PCM ilungise le nkinga. Okulandelayo, thola inzwa yokucindezela kwegesi ephumayo emotweni yakho bese unqamula ishubhu eliyixhuma exhaust manifold.

Zama ukusula leli shubhu kunoma iyiphi ikhabhoni engase ibangele ikhodi ye-P0470. Uma ishubhu lihlanzekile, hlola izixhumi nezintambo zokulimala noma ukugqwala. Okulandelayo, hlola amandla angu-5V namasekhethi esignali yenzwa usebenzisa i-digital volt-ohmmeter (DVOM).

Qiniseka ukuthi inzwa isekelwe kahle. Uma zonke izivivinyo zidlula, kungase kudingeke ukushintshwa kwenzwa yokucindezela kwegesi ephumayo. Uma ikhodi ye-P0470 iqhubeka nokuvela, i-PCM engalungile ingase futhi ibe imbangela, kodwa ingakhishwa kuphela ngemva kokufaka inzwa nokwenza izivivinyo ezengeziwe.

Amaphutha okuxilonga

Izimbangela ezingaba khona zekhodi ye-P0470

Lapho uxilonga ikhodi ye-P0470, kubalulekile ukucabangela izimbangela ezimbalwa ezingase ziholele kule khodi. Ngezansi izinto ezibalulekile okufanele zicatshangelwe:

  1. Ukuvinjwa kushubhu kusuka ku-exhaust manifold kuya kunzwa yokucindezela: Esinye isimo esingenzeka ukuthi i-carbon yakheka ohlelweni lwe-exhaust, engabangela ukuvinjelwa kwe-tube lapho inzwa yokucindezela ithola ulwazi. Lokhu kungase kubangele ukufundwa okungalungile kanye nekhodi P0470.
  2. Izinkinga ngohlelo lwe-exhaust gas recirculation (EGR), ukungenisa komoya noma ukushaja ukuvuza komoya: Izinkinga nge-exhaust noma izinhlelo zokunikezela komoya zingathinta ingcindezi ohlelweni lokukhipha umoya futhi zibangele ikhodi ye-P0470. Ukuxilongwa okuthembekile kwalezi zingxenye kungaba isinyathelo esibalulekile.
  3. Ukungasebenzi kahle kwenzwa ye-Exhaust gas pressure: Inzwa yokucindezela kwegesi ephumayo ngokwayo ingase yehluleke noma ikhiqize amasignali angalungile, okuholela kukhodi ye-P0470.
  4. Izinkinga zenzwa ye-Exhaust Back Pressure (EBP): Inzwa ye-backpressure exhaust iyingxenye ebalulekile yesistimu yokulawula injini futhi ingahlotshaniswa nekhodi ye-P0470.
  5. Izinkinga ngezintambo nokuxhumeka kukagesi: Izintambo ezilimele, ukugqwala, noma ukuxhumeka kukagesi okungalungile phakathi kwezinzwa nohlelo lokulawula kungabangela amasignali angalungile kanye nekhodi ye-P0470.

Lezi zimbangela ezingaba khona zekhodi ye-P0470 zibalulekile ukuthi zicatshangelwe ngesikhathi sokuxilongwa nokulungiswa ukuze kukhonjwe futhi kulungiswe umsuka wenkinga.

Ibucayi kangakanani ikhodi yephutha? P0470?

Ikhodi yenkinga P0470 ikhombisa inkinga ngenzwa yokucindezela kwegesi ephumayo noma ingcindezi yesistimu yokukhipha umoya. Lokhu kungase kuthinte ukusebenza kwenjini, ukusebenza nokusetshenziswa kukaphethiloli. Nakuba lesi kungesona isimo esiphuthumayo esibucayi, ukungasebenzi kahle okungaholela ezinkingeni ezinkulu uma kungalungiswa. Kunconywa ukuthi injini yakho ixilongwe futhi ilungiswe umakhenikha uma ikhodi ye-P0470 ibonakala ivimbela ukonakala kwenjini futhi igcine ukusebenza kwenjini.

Yikuphi ukulungisa okuzosiza ukuqeda ikhodi? P0470?

Ukuxazulula ikhodi ye-P0470 kuhilela izinyathelo ezimbalwa, kuye ngesizathu esihlonziwe:

  1. Ihlola Izincwadi Zesevisi Yezobuchwepheshe (TSB): Qala ngokubheka ulwazi kumanqampunqampu wesevisi yezobuchwepheshe, angase aqukathe izincomo zomkhiqizi zokuxazulula le nkinga. Umkhiqizi angase anikeze ukukhanya/ukukhanyisa kabusha kwe-PCM okungase kusule ikhodi.
  2. Ukuhlola inzwa yokucindezela kokukhipha umoya: Nqamula inzwa yokucindezela kwegesi ephumayo futhi uhlole amadiphozithi ekhabhoni noma umonakalo. Hlanza noma shintsha inzwa uma kunesidingo.
  3. Ukuhlola izintambo: Hlola ngokubuka izintambo, bheka umonakalo, ukugqwala noma izintambo eziphukile. Nqamula izixhumi futhi uzihlanze uma kunesidingo.
  4. Ihlola amandla namasekhethi esignali: Usebenzisa imitha yedijithali ye-volt-ohm (DVOM), hlola amandla angu-5V namasekhethi esignali aya kunzwa. Qiniseka ukuthi i-voltage ihlangabezana nezicaciso zomkhiqizi.
  5. Ukuhlola phansi: Hlola ukuthi ingabe inzwa yokucindezela kwegesi ephumayo isekelwe kahle yini.
  6. Ukuhlola ishubhu nokuxhumana: Hlola ngokucophelela ishubhu elixhuma i-turbocharger endaweni eningi yokuyithatha ukuze ivuze.
  7. Ukusula amaphutha: Sebenzisa iskena se-OBD-II ukuze usule ikhodi ye-P0470 kumemori ye-PCM. Ngemva kwalokhu, shayela imoto futhi uhlole ukuthi iphutha liyavela futhi.
  8. Ukushintshwa kwenzwa: Uma inkinga ingenakuxazululwa ngezinye izindlela, buyisela inzwa yokucindezela kwegesi yokukhipha.
  9. Ukuhlola kwe-PCM: Uma zonke lezi zinyathelo ezingenhla zingayixazululi inkinga, kungase kube nenkinga nge-PCM. Kodwa-ke, le nketho kufanele ibhekwe kuphela njengesisetshenziswa sokugcina.

Khumbula ukuthi ukuxilongwa nokulungiswa kufanele kwenziwe umakhenikha oqeqeshiwe noma isikhungo sesevisi ukuze kuqinisekiswe imbangela eqondile kanye nokuxazululwa okusebenzayo kwekhodi ye-P0470.
