I-P0474 isignali yesekethe yokuzwa ingcindezi engapheli

I-P0474 - I-OBD-II Ikhodi Yenkinga Incazelo Yobuchwepheshe

Ikhodi yenkinga engu-P0474 ibonisa ukuthi i-PCM ithole isignali yesifunda senzwa yokucindezela kwegesi ephumayo.

Isho ukuthini ikhodi yephutha P0474?

Ikhodi yenkinga P0474 ikhombisa isignali yesikhashana kusekethe yenzwa yokucindezela kwegesi ephumayo. Ukucindezelwa kwegesi ephumayo kuvame ukugadwa ezimotweni ezinodizili nezinjini ezishajayo. Inzwa yokucindezela kwegesi ephumayo inikeza ukufundwa kwe-voltage ku-ECM (imojula yokulawula injini) ukuze inqume izinga lamanje lokucindezela. Uma inani langempela lokucindezela lihluka enanini elicaciswe kuzicaciso zomkhiqizi, kuzovela ikhodi engu-P0474.

Izizathu ezingenzeka

Ezinye izizathu ezingenzeka zekhodi yenkinga ye-P0474:

• Khipha inzwa yengcindezi yegesi: Ikhwalithi yesignali engalungile evela kunzwa yokucindezela kwegesi ephumayo ingase ibangelwe ukuguga, ukulimala noma ukungasebenzi kahle.
• Izinkinga zikagesi: Ukuvula, ukugqwala noma ukulimala kumjikelezo kagesi oxhuma inzwa yokucindezela kwegesi ephumayo ku-PCM (imojula yokulawula injini) kungabangela isignali yesikhashana.
• Izinkinga ze-PCM: Ukungasebenzi kahle noma amaphutha esofthiwe ku-PCM angabangela i-P0474.
• Ukulimala ngomshini: Ukulimala noma ukuguqulwa ohlelweni lwe-exhaust, njengokuvuza, ukuvinjwa noma izinkinga nge-exhaust manifold, kungabangela ukungazinzi ekucindezelweni kwegesi yokukhipha kanye nomlayezo wephutha.
• Izinkinga ze-Turbo: Ezimotweni ezine-turbocharged, izinkinga nge-turbo noma i-boost control valve zingabangela ingcindezi engazinzile ohlelweni lwe-exhaust.

Lezi yizimbangela ezivamile nje futhi kunconywa ukuthi kwenziwe olunye ukuxilongwa ukuze kutholakale inkinga.

Yiziphi izimpawu zekhodi yephutha? P0474?

Izimpawu zekhodi yenkinga engu-P0474 zingahluka kuye ngembangela ethile nokwakheka kwemoto, ezinye izimpawu ezivamile ezingase zenzeke yilezi:

• Hlola Engine Light Ikhanyisa: Olunye lwezimpawu zokuqala zenkinga kungaba ukusebenza kwesibani se-Check Engine kudeshibhodi yakho.
• Ukulahleka kwamandla enjini: Isignali yenzwa yegesi ephumayo engazinzile ingase ibangele injini ukuba iphelelwe amandla noma ingasebenzi kahle.
• Idle engazinzile: Uma i-exhaust gas pressure ingazinzile ngokwanele, isivinini sokungenzi lutho senjini singase sithinteke.
• Ukwanda kokusetshenziswa kukaphethiloli: Ingcindezi yesistimu yokukhipha umoya engazinzile ingase ibangele ukukhuphuka kokusetshenziswa kukaphethiloli.
• Izinkinga ze-Turbocharging (zezimoto ezine-turbocharged): Endabeni yezimoto ezine-turbocharged, ukuntengantenga kwe-boost kungenzeka, okungase futhi kuholele ekulahlekelweni kwamandla nezinye izinkinga zenjini.

Uma usola inkinga ngenzwa yakho yokucindezela kwegesi ephumayo noma uqaphela izimpawu ezingenhla, kutuswa ukuthi uyiyise kumakhenikha oqeqeshiwe ukuze ixilongwe futhi ilungiswe.

Indlela yokuxilonga ikhodi yephutha P0474?

Nge-DTC P0474, landela lezi zinyathelo zokuxilonga:

• Ihlola ukuxhumana nezintambo: Hlola konke ukuxhumeka kukagesi nezintambo ezixhuma inzwa yokucindezela kwegesi ephumayo kumojula yokulawula injini (PCM) noma injini. Naka ukulimala okungenzeka, ukugqwala noma amakhefu.
• Ihlola inzwa yokucindezela kwegesi ephumayo: Sebenzisa i-multimeter ukuze uhlole ukusebenza kwenzwa yokucindezela kwegesi ephumayo. Hlola ukumelana kwayo namandla kagesi ngaphansi kwezimo ezihlukene zokusebenza kwenjini. Qhathanisa amanani atholiwe nedatha yobuchwepheshe yomkhiqizi.
• Ukuhlola ingcindezi ohlelweni lwe-exhaust: Linganisa ingcindezi yangempela ohlelweni lwe-exhaust usebenzisa i-gauge ye-exhaust pressure. Qinisekisa ukuthi umfutho olinganisiwe ufana nokucindezela okulindelekile ngokuya ngezicaciso zomkhiqizi.
• Ihlola i-turbocharging (uma ifakwe): Uma imoto yakho ifakwe i-turbocharger, qiniseka ukuthi isebenza ngendlela efanele. Hlola i-turbocharger kanye nesistimu yokuphakelwa komoya ukuvuza noma ukulimala.
• Ukuxilongwa kwe-PCM: Uma zonke ezinye izingxenye zihlolwa futhi ungatholi zinkinga, kungase kube nenkinga nge-PCM. Thola imojuli yokulawula injini usebenzisa okokusebenza okufanele, noma uthinte uchwepheshe ukuze uthole ukuxilonga okuningiliziwe.

Ngemva kokuqeda lezi zinyathelo, uzokwazi ukukhomba imbangela futhi uxazulule inkinga ebangela ikhodi yenkathazo ye-P0474.

Amaphutha okuxilonga

Lapho uxilonga i-DTC P0474, kungenzeka amaphutha alandelayo:

1. Ukuchazwa kabi kwezimpawu: Ezinye izimpawu zingase zidideke noma zifane nezinye izinkinga. Isibonelo, izinkinga nge-turbocharging noma isignali yenzwa yengcindezi yegesi ephumayo ingalingisa amanye amaphutha, okungaholela ekuxilongweni okungalungile.
2. Ukuhlola okunganele kokuxhunywa kukagesi: Ukuhlolwa kokuxhunywa kukagesi okungalungile noma okungaphelele kungabangela inkinga ukuthi ibonwe ngokungalungile. Kubalulekile ukwenza isiqiniseko sokuthi zonke izintambo ziqinile, izintambo zilungile futhi akukho ukugqwala.
3. Ukweqa ukuxilongwa kwezinye izingxenye: Kwesinye isikhathi ukuxilonga kukhawulelwe ekuhloleni kuphela inzwa yokucindezela kwegesi ephumayo, futhi ezinye izingxenye zesistimu azihlolwa kahle. Lokhu kungase kubangele ukuthi uphuthelwe ezinye izinkinga ezingase zibangele ikhodi ye-P0474.
4. Ukuchazwa kabi kwemiphumela yokuhlolwa: Ukuchazwa okungalungile kwemiphumela yokuhlolwa noma yokulinganisa kungase kuholele eziphethweni ezingalungile mayelana nempilo yohlelo. Kubalulekile ukuhumusha kahle idatha etholwe ngesikhathi senqubo yokuxilonga.
5. Amathuluzi noma amathuluzi anganele: Ukusebenzisa imishini yokuxilonga engalungile noma enganele kungaholela emiphumeleni engalungile kanye neziphetho eziyiphutha.

Ukuze ugweme lawa maphutha, kubalulekile ukwenza ngokucophelela isinyathelo ngasinye sokuxilonga, hlola zonke izingxenye zesistimu, futhi usebenzise imishini efanele.

Ibucayi kangakanani ikhodi yephutha? P0474?

Ikhodi yenkinga P0474 ikhombisa inkinga ngenzwa yokucindezela kwegesi ephumayo. Ngokuya ngembangela ethile yale nkinga, ubunzima bekhodi ye-P0474 bungahluka.

Uma inkinga ibangelwa kuphela ukungasebenzi kahle kwenzwa yesikhashana noma inkinga kagesi, kungase kungabi yingozi enkulu ekuphepheni kokushayela noma ekusebenzeni kwenjini. Kodwa-ke, uma inkinga ingenxa yokulimala kwangempela kwenzwa noma ezinye izingxenye zesistimu yokulawula injini, kungase kubangele ukusebenza kabi kwenjini, ukwanda kokukhishwa kwezinto ezikhishwayo, ukuncipha komnotho kaphethiloli, futhi ekugcineni kungenzeka nomonakalo wenjini.

Kunoma yikuphi, ikhodi ye-P0474 kufanele ibuyekezwe ngokucophelela futhi ixazululwe ngokushesha ngangokunokwenzeka ukuze kugwenywe ezinye izinkinga zokusebenza kwenjini nokunciphisa ukuthembeka kwenjini. Uma ukukhanya kwe-MIL (Injini Yokuhlola) kukhanyisa kudeshibhodi yakho, kuyatuswa ukuthi uyixilonge futhi ilungiswe uchwepheshe oqeqeshiwe.

Yikuphi ukulungisa okuzosiza ukuqeda ikhodi? P0474?

Ukulungiswa okudingekayo ukuze kuxazululwe ikhodi yenkathazo ye-P0474 kuzoncika kumbangela ethile yaleli phutha, kunezenzo ezimbalwa ezingenzeka ezingasiza ukuxazulula le khodi:

1. Ukushintsha i-Exhaust Gas Pressure Sensor: Uma inzwa inephutha noma ilimele, ukuyishintsha ngokuvamile kuzoxazulula inkinga. Inzwa kufanele ishintshwe kufakwe entsha ehambisana nemodeli ethile kanye nokwakheka kwemoto.
2. Ukuhlola nokuhlanza uxhumo lukagesi: Kwesinye isikhathi inkinga ingabangelwa ukuthintana kahle noma ukugqwala ekuxhumekeni kukagesi phakathi kwenzwa kanye nemojula yokulawula injini. Hlola ukuxhumana futhi ukuhlanze noma ukulungise uma kudingeka.
3. Ukuxilongwa nokulungiswa kwezinye izingxenye zesistimu: Ngaphandle kwenzwa yokucindezela kwegesi ephumayo, inkinga ingase ihlotshaniswe nezinye izingxenye ze-exhaust noma uhlelo lokuphatha injini. Lokhu kungase kuhlanganise ukuhlola nokufaka esikhundleni se-valve ye-EGR (exhaust gas recirculation), inzwa yokucindezela kwe-turbo, ama-gaskets namapayipi aphumayo, nezinye izinto.
4. Isibuyekezo Sesofthiwe ye-PCM: Kwesinye isikhathi ukuvuselela isofthiwe yemojula yokulawula injini (PCM) kungaxazulula inkinga uma iphutha libangelwa iphutha lesofthiwe.

Kunconywa ukuthi ube nomakhenikha wezimoto oqeqeshiwe noma isitolo sokukhanda izimoto futhi ulungise ikhodi ye-P0474. Bazokwazi ukucacisa kahle imbangela yephutha futhi benze umsebenzi wokulungisa odingekayo.
