I-P0639 I-Throttle Actuator Range/Ipharamitha B2

I-P0639 - I-OBD-II Ikhodi Yenkinga Incazelo Yobuchwepheshe

Ibanga/Ukusebenza Kwe-Throttle Actuator (Ibhange 2)

Isho ukuthini ikhodi yephutha P0639?

Ezinye izimoto zesimanje zinesistimu yokulawula i-drive-by-wire throttle ehlanganisa inzwa ku-accelerator pedal, i-powertrain/injini yokulawula module (PCM/ECM), kanye ne-throttle actuator motor. I-PCM/ECM isebenzisa inzwa ye-throttle position (TPS) ukuze iqaphe ukuma kwangempela kwe-throttle. Uma lesi sikhundla singaphandle kwevelu eshiwo, i-PCM/ECM isetha i-DTC P0638.

Qaphela ukuthi "ibhange 2" libhekisela ohlangothini lwenjini oluphambene nesilinda inombolo eyodwa. Ngokuvamile kuba khona i-throttle valve yebhange ngalinye lamasilinda. Ikhodi P0638 ikhombisa inkinga kule ngxenye yesistimu. Uma womabili amakhodi e-P0638 kanye ne-P0639 etholwa, kungase kubonise izinkinga zezintambo, ukuntuleka kwamandla, noma izinkinga nge-PCM/ECM.

Iningi lala ma-throttle valve alikwazi ukulungiswa futhi lidinga ukushintshwa. I-throttle body ivamise ukubanjwa ivuliwe lapho injini ihluleka. Uma i-throttle valve inephutha ngokuphelele, imoto ingashayelwa kuphela ngesivinini esiphansi.

Uma amakhodi ahlobene nenzwa ye-throttle position etholakala, kufanele alungiswe ngaphambi kokuhlaziya ikhodi ye-P0639. Le khodi ibonisa iphutha kusistimu yokulawula i-throttle actuator ebhange 2 lenjini, ngokuvamile elingenayo inombolo yesilinda sokuqala. Amanye amamojula okulawula angase athole leli phutha futhi kuwo ikhodi izoba ngu-P0639.

Izizathu ezingenzeka

Ikhodi yenkinga engu-P0639 ingenzeka ngenxa yezinkinga zokulawula i-throttle actuator, i-actuator ngokwayo, noma inzwa ye-throttle position. Futhi, izintambo ezingalungile zenethiwekhi (CAN), ukubeka phansi okungafanele, noma izinkinga ngezintambo eziphansi kumamojula okulawula kungabangela lo mlayezo. Isizathu esingenzeka futhi kungaba nenkinga ebhasini le-CAN.

Ngokuvamile, ikhodi P0639 ihlotshaniswa ne:

1. Inkinga ngenzwa yokuma kwephedali.
2. Inkinga ngenzwa yokuma kwe-throttle.
3. Ukuhluleka kwe-throttle motor.
4. Umzimba we-throttle ongcolile.
5. Izinkinga zezintambo, okuhlanganisa ukuxhumana okungenzeka kungcolile noma okuxekethile.
6. I-PCM/ECM (imojula yokulawula injini) ukungasebenzi kahle.

Uma kwenzeka ikhodi ye-P0639, ukuxilonga okuningiliziwe kufanele kwenziwe ukuze kutholwe imbangela ethile futhi kuthathwe izinyathelo ezifanele zokuyilungisa.

Yiziphi izimpawu zekhodi yephutha? P0639?

Izimpawu ezilandelayo zingase zenzeke nge-DTC P0639:

1. Izinkinga ngokuqalisa injini.
2. Imililo engalungile, ikakhulukazi egiyeni elingathathi hlangothi.
3. Injini iyama ngaphandle kwesixwayiso.
4. Kuphuma intuthu emnyama ohlelweni lwe-exhaust uma uqala imoto.
5. Ukuwohloka kokusheshisa.
6. Inkomba yokuthungela ihlola injini (Hlola Injini).
7. Ukuzwa ukungabaza lapho usheshisa.

Indlela yokuxilonga ikhodi yephutha P0639?

Inzwa yesikhundla segesi etholakala ku-pedal ngokwayo futhi ngokuvamile ixhunywe ngezintambo ezintathu: i-voltage yereferensi engu-5 V, umhlabathi nesiginali. Hlola izintambo ukuze uthole uxhumano oluvikelekile futhi azikho izindawo ezixekethile. Futhi hlola umhlabathi usebenzisa i-volt-ohmmeter kanye ne-voltage yesithenjwa engu-5V evela ku-PCM.

I-voltage yesiginali kufanele ihluke ukusuka ku-0,5 V uma i-pedal ingacindezelwa ukuya ku-4,5 V uma ivuliwe ngokugcwele. Kungase kudingeke ukuhlola isignali ku-PCM ukuze ifane nenzwa. I-multimeter eyisithombe noma i-oscilloscope ingasiza ekunqumeni ukushelela kokushintsha kwamandla kagesi kulo lonke uhla lokunyakaza.

Inzwa yesimo sempintsha futhi inezintambo ezintathu futhi idinga ukuhlola uxhumo, umhlabathi, kanye ne-voltage eyireferensi engu-5V. Buka izinguquko zikagesi uma ucindezela i-pedal yegesi. Hlola injini ye-throttle ukumelana, okufanele ibe ngaphakathi kwemininingwane yefekthri. Uma ukumelana kungavamile, injini ingase inganyakazi njengoba kulindelekile.

I-throttle motor isebenza ngokususelwe kusiginali esuka endaweni yokunyathela kanye namapharamitha achazwe ngaphambilini alawulwa yi-PCM/ECM. Hlola ukumelana kwemoto ngokunqamula isixhumi futhi usebenzise i-volt-ohmmeter ukuze uqinisekise ukuthi ingaphakathi kwezicaciso zasembonini. Futhi hlola izintambo usebenzisa umdwebo wefekthri ukuze uthole izintambo ezifanele.

Ngomjikelezo womsebenzi wenjini, sebenzisa i-graphing multimeter noma i-oscilloscope ukuze uqinisekise ukuthi ifana nephesenti elibekwe yi-PCM/ECM. Ithuluzi lokuskena elithuthukisiwe lingadingeka ukuze kuhlolwe okunembile.

Hlola umzimba we-throttle ngokuba khona kwezithiyo, ukungcola noma amafutha angase aphazamise ukusebenza kwawo okuvamile.

Hlola I-PCM/ECM usebenzisa ithuluzi lokuskena ukuze uhlole ukuthi isignali yokufaka oyifunayo, indawo ephihliza ngempela, kanye nendawo eqondiwe yokuma kwenjini. Uma amanani engafani, kungase kube nenkinga yokumelana nezintambo.

Izintambo zingabhekwa ngokunqamula inzwa nezixhumi ze-PCM/ECM nokusebenzisa i-volt-ohmmeter ukuhlola ukumelana kwezintambo. Amaphutha ezintambo angabangela ukuxhumana okungalungile ne-PCM/ECM futhi kubangele amakhodi amaphutha.

Amaphutha okuxilonga

Lapho uxilonga ikhodi yenkathazo ye-P0639, omakanika abaningi bavame ukwenza iphutha lokugxila kuphela kuzimpawu namakhodi agciniwe. Indlela esebenza kahle kakhulu yokubhekana nale nkinga iwukulayisha idatha yozimele wokufriza futhi uhlaziye amakhodi ngendlela agcinwe ngayo. Lokhu kuzokuvumela ukuthi ukhombe ngokunembile futhi uqede imbangela yephutha P0639.

Ibucayi kangakanani ikhodi yephutha? P0639?

Ikhodi yenkinga engu-P0639, nakuba ingabangeli izinkinga ngokushesha ngokusebenza kwemoto, kufanele ihlolwe futhi ilungiswe ngokushesha ngangokunokwenzeka. Uma iyekwa inganakiwe, le khodi ekugcineni ingaholela ezinkingeni ezinkulu njengokungaqali kwenjini noma ukuma ngendlela engavamile. Ngakho-ke, kunconywa ukwenza ukuxilongwa nokulungiswa ukuze kuvinjelwe izinkinga ezingase zibe khona.

Yikuphi ukulungisa okuzosiza ukuqeda ikhodi? P0639?

Ukuze uxazulule inkinga futhi usethe kabusha ikhodi ye-P0639, kunconywa ukuthi umakhenikha wakho enze lezi zinyathelo zokulungisa ezilandelayo:

1. Shintshanisa noma yiziphi izintambo ezinokukhubazeka noma ezilimele, izixhumi noma izingxenye ezihlobene nesistimu ye-throttle.
2. Uma kutholakala ukungasebenzi kahle kwe-throttle valve drive motor, kufanele kushintshwe esebenzayo.
3. Uma kudingeka, shintsha wonke umzimba we-throttle, okuhlanganisa inzwa yokuma kwe-throttle, njengoba kunconywe umenzi.
4. Lapho ushintsha umzimba we-throttle, umakhenikha kufanele futhi acabangele ukufaka esikhundleni senzwa yokunyathela, uma kucacisiwe.
5. Shintshanisa wonke amamojula okulawula anephutha, uma ekhona.
6. Xhuma noma shintsha noma yiziphi izixhumi zikagesi ezixegayo, ezigqwalile noma ezilimele ohlelweni.
7. Shintshanisa noma yiziphi izintambo ezingalungile kwihhanisi lamabhasi e-CAN uma zikhonjwa njengomthombo wenkinga.

Ukuxilongwa ngokucophelela nokuqaliswa kwezinyathelo ezishiwo kuzosiza ukuqeda ikhodi ye-P0639 futhi kubuyisele imoto ekusebenzeni okujwayelekile.
