P0643 Reference voltage sensor circuit “A” high

I-P0643 - I-OBD-II Ikhodi Yenkinga Incazelo Yobuchwepheshe

Ikhodi yenkinga engu-P0643 ikhombisa ukuthi i-voltage kusekethe kagesi yereferensi yenzwa “A” iphezulu kakhulu (uma iqhathaniswa nenani elicaciswe ekucacisweni komkhiqizi).

Isho ukuthini ikhodi yephutha P0643?

Ikhodi yenkinga engu-P0643 ikhombisa ukuthi i-sensor reference voltage circuit "A" iphezulu kakhulu uma iqhathaniswa nokucaciswa komkhiqizi. Lokhu kusho ukuthi imojula yokulawula i-powertrain (i-PCM), imojula yokulawula injini (ECM), noma enye imojuli yokulawula insiza yemoto ithole i-voltage ephezulu ngokungavamile kule sekethi. I-Engine Control Module (ECM) ngokuvamile inamasekhethi amathathu ayizithenjwa angu-5-volt aphakela izinzwa ezihlukahlukene. Isekethe ngayinye iklanyelwe ukunikeza i-voltage yereferensi kuzinzwa ezithile. Imvamisa, isekethe ethi “A” inesibopho sokuhlinzeka nge-voltage eyireferensi kunzwa ye-accelerator pedal position.

Izizathu ezingenzeka

Ezinye izizathu ezingenzeka zekhodi ye-P0643:

• Intambo eyonakele noma isixhumi kumjikelezo wevolthi yesithenjwa: Ukulimala kwezintambo noma izixhumi kungabangela isifunda esifushane noma esivulekile, esingabangela i-voltage ephezulu.
• Ukungasebenzi kahle kwenzwa: Uma inzwa ethola i-voltage yereferensi evela kusekethe "A" ilimele noma ingasebenzi kahle, ingabangela i-voltage ephezulu ngokungavamile kusekethe.
• Imojula yokulawula injini (ECM) noma ukungasebenzi kahle kwemojuli yokulawula i-powertrain (PCM): Imojula yokulawula imoto ngokwayo ingase yonakale noma ingasebenzi kahle, kuyenze ikhiqize amasignali kagesi angalungile.
• Izinkinga ngesistimu yokubeka phansi: Ukubeka phansi okungafanele nakho kungabangela amaphutha kumjikelezo wereferensi kagesi, okungabangela ukuthi ikhodi P0643 ivele.
• Iphutha le-generator: Uma i-alternator yemoto yakho ihluleka noma ikhiqiza amandla kagesi amaningi, ingase futhi ibangele i-P0643.

Yiziphi izimpawu zekhodi yephutha? P0643?

Ezinye izimpawu ezingaba khona lapho ikhodi yenkathazo P0643 ikhona:

• Hlola Injini Inkomba: Uma i-P0643 ikhona, i-Check Engine Light noma i-MIL (I-Malfunction Indicator Lamp) ingase ikukhanyise kudeshibhodi yakho ukukhombisa inkinga.
• Ukulahlekelwa Amandla: Kungase kube nokuncipha noma ukulahlekelwa amandla enjini ngenxa yokusebenza okungalungile kwesistimu yokulawula.
• Ukungenzi lutho okungazinzile: Imoto ingase ibe nokungenzi lutho noma okunyakazayo ngenxa yezinzwa ezingasebenzi kahle noma isistimu yokulawula.
• Uwonga uphethiloli ongemuhle: Ukwenyuka kokusetshenziswa kukaphethiloli noma ukuncipha kokusebenza kahle kungase kube ngenxa yokusebenza okungafanele kwesistimu yokulawula.
• Isivinini esingazinzile: Izinkinga ngesivinini senjini zingase zenzeke, njengokuhlengezela noma ukushintsha kwejubane ngaphandle kwesizathu esibonakalayo.

Indlela yokuxilonga ikhodi yephutha P0643?

Izinyathelo ezilandelayo ziyanconywa ukuxilonga nokuxazulula i-DTC P0643:

1. Ihlola ukuxhumana nezintambo: Hlola konke ukuxhumeka kukagesi okuhlotshaniswa nesekhethi yereferensi yenzwa ethi “A”, okuhlanganisa izixhumi, izikhonkwane, nezintambo ngomonakalo, ukugqwala, noma ukunqamuka.
2. Ukuhlola amandla kagesi: Usebenzisa i-multimeter, kala i-voltage kusekethe "A" ye-voltage yereferensi yenzwa. Qiniseka ukuthi i-voltage ihlangabezana nezicaciso zomkhiqizi.
3. Ihlola izinzwa: Hlola isimo kanye nokusebenza kwezinzwa ezithola i-voltage yereferensi kusekethe ethi “A”. Qiniseka ukuthi izinzwa azonakalanga futhi zixhumeke ngendlela efanele.
4. Ihlola Imojula Yokulawula Injini (ECM): Hlola imojuli yokulawula injini ukuze uthole amaphutha noma ukungasebenzi kahle. Imishini ekhethekile yokuxilonga ye-ECM ingase idingeke.
5. Setha kabusha amaphutha: Ngemva kokuhlola kahle nokulungisa inkinga, setha kabusha ikhodi yenkinga futhi uyithathe uyihlole ukuze uqiniseke ukuthi inkinga ixazululiwe.

Uma inkinga ingeke ikhonjwe noma ixazululwe uwedwa, kutuswa ukuthi uxhumane nochwepheshe bezimoto abaqeqeshiwe noma isitolo sokulungisa izimoto ukuze uxilongwe futhi ulungiswe.

Amaphutha okuxilonga

Lapho uxilonga i-DTC P0643, kungenzeka amaphutha alandelayo:

• Ukuchazwa okungalungile kwedatha: Elinye lamaphutha amakhulu kungaba ukuchazwa okungalungile kwedatha etholwe lapho kuhlolwa i-voltage noma isimo se-wiring. Lokhu kungase kuholele ekunqumeni okuyiphutha kwembangela yokungasebenzi kahle.
• Ukushintshwa kwengxenye okungalungile: Uma ukuxilongwa okuphelele kungenziwanga, kunengozi yokushintsha izingxenye ngokungadingekile. Lokhu kungaholela ekusetshenzisweni kwesikhathi esengeziwe nezinsiza ngaphandle kokuxazulula inkinga ewumsuka.
• Ukuziba ezinye izinkinga ezingaba khona: Ngokugxila enkingeni eyodwa, ungase uphuthelwe ezinye izimbangela zokwehluleka. Kubalulekile ukucabangela zonke izici ezingenzeka ezithinta i-sensor voltage reference circuit.
• Ukuxhumeka kwenzwa okungalungile: Lapho uhlola izinzwa, kufanele uqinisekise ukuthi zixhumeke ngendlela efanele futhi zihlangabezana nezimfuneko zomkhiqizi. Ukuxhumeka okungalungile kungase kuholele emiphumeleni yokuxilonga engalungile.
• Izinkinga zezingxenyekazi zekhompuyutha: Amathuluzi okuxilonga anganembile ngokwanele noma anephutha angaholela eziphethweni ezingalungile. Kubalulekile ukusebenzisa amathuluzi athembekile futhi alinganisiwe ukuze kutholakale ukuxilongwa okunembile.

Ukuze ugweme lawa maphutha, kunconywa ukwenza ukuxilongwa ngokucophelela, ngokulandela izinqubo nezincomo zomkhiqizi, futhi, uma kunesidingo, funa usizo ochwepheshe abanolwazi.

Ibucayi kangakanani ikhodi yephutha? P0643?

Ikhodi yenkinga engu-P0643 ibonisa ukuthi isifunda se-voltage yesithenjwa senzwa siphezulu kakhulu. Lokhu kungaba yinkinga enkulu ephazamisa ukusebenza kwezinhlelo zezimoto ezahlukene njenge-fuel injection system, ignition system nezinye. Uma ingalungiswanga, le nkinga ingaholela ekusebenzeni kabi kwenjini, ukuphelelwa amandla, ukonga kahle kukaphethiloli, nokwanda kwesisi esikhipha umoya.

Ngaphezu kwalokho, i-voltage enganele kumjikelezo kagesi wereferensi ingabangela izinkinga ngohlelo lokuphatha injini nezinye izinhlelo zezimoto, ezingathinta ukuphepha nokuthembeka kokushayela.

Ngakho-ke, nakuba le khodi yenkinga ingase ingabi bucayi ngokushesha, kubalulekile ukuyithatha ngokungathi sína futhi ixilongelwe futhi ilungiswe ngokushesha ngangokunokwenzeka ukuze ugweme imiphumela emibi kakhulu.

Yikuphi ukulungisa okuzosiza ukuqeda ikhodi? P0643?

Ukuze uxazulule i-DTC P0643, landela lezi zinyathelo:

1. Ukuhlola I-Reference Voltage Circuit: Okokuqala, hlola umjikelezo we-voltage yereferensi wezikhindi noma ukuvula. Lokhu kungenziwa ngokusebenzisa i-multimeter ngokulinganisa i-voltage kuzikhonkwane zokuxhuma ezihambisanayo.
2. Ukuhlola Izinzwa Nezinzwa Ze-Accelerator Pedal: Hlola izinzwa ezinikwa amandla i-reference voltage circuit, njengenzwa ye-accelerator pedal position. Qiniseka ukuthi zisebenza kahle futhi zine-voltage efanele.
3. Hlola Izintambo Nezixhumi: Hlola izintambo nezixhumi ukuze ubone umonakalo, ukugqwala, noma abathintwayo abampofu. Lungisa noma shintsha izingxenye ezilimele.
4. Ukushintsha i-PCM/ECM: Uma zonke lezi zinyathelo ezingenhla zingayixazululi inkinga, i-PCM/ECM ngokwayo ingase ibe nephutha. Kulokhu, ukushintshwa noma ukuhlelwa kabusha kwemodyuli yokulawula injini kuyadingeka.
5. Izinyathelo zokulungisa ezengeziwe: Ngezinye izikhathi inkinga ingabangelwa ezinye izici, njengokujikeleza okufushane kwenye isistimu yemoto. Kulokhu, ukuxilonga okwengeziwe nokulungiswa kuyadingeka.

Ngemva kokuqeda lezi zinyathelo, kufanele uhlole imoto ukuze ubone ukuthi ingabe iphutha lenzekile. Uma kwenziwa kahle, ikhodi ye-P0643 kufanele ixazulule. Uma inkinga iqhubeka, kunconywa ukuthi uxhumane nochwepheshe bokuxilonga imoto nokulungisa ukuze uthole ukuhlaziya okujulile.
