Isifunda se-P252C se-injini esezingeni eliphansi

Idatha ye-OBD-II DTC

Izinga lesiginali eliphansi esiteshini senzwa yekhwalithi kawoyela wenjini

Kusho ukuthini lokhu?

Le yiGeneric Powertrain Diagnostic Trouble Code (DTC) esebenza ezimotweni eziningi ze-OBD-II (1996 nezintsha). Lokhu kungafaka, kodwa kungagcini lapho, izimoto ezivela kwaGeneral Motors, VW, Ford, BMW, Mercedes, njll. Naphezu kohlobo olujwayelekile, izinyathelo eziqondile zokulungisa zingahluka ngokuya ngohlobo lwemodeli, ukwakheka, imodeli nokwakheka kokudluliswa.

I-OBD-II DTC P252C namakhodi ahambisanayo P252A, P252B, P252D kanye ne-P252E ahlotshaniswa nesekethe lenzwa yekhwalithi kawoyela.

Isekethe yesenseli yekhwalithi kawoyela yakhelwe ukuthumela isignali kwimodyuli yokulawula injini (ECM) ekhombisa isimo esiphelele samafutha enjini. Lesi sifunda sihlola ikhwalithi, izinga lokushisa kanye nezinga lamafutha enjini. Inzwa yekhwalithi kawoyela wenjini ingenye yezinto eziyinhloko kulesi sifunda futhi itholakala epanini likawoyela wenjini. Indawo ngqo nokusebenza kwenzwa kuyahlukahluka kuye ngemoto, kepha inhloso yalesi sifunda iyafana. Ukulungiswa kuzohluka ngezinsimbi ezakhelwe ukuqapha uwoyela wenjini nokubonisa isimo kudeshibhodi ukuxwayisa umshayeli. Ezinye izimoto zingafakelwa izinzwa noma izinkomba zokushisa kukawoyela, izinga lamafutha kanye / noma ingcindezi kawoyela.

Lapho i-ECM ithola ukuthi amandla kagesi noma ukumelana nesekethe lenzwa yekhwalithi kawoyela kuphansi kakhulu, ngaphansi komkhawulo ojwayelekile webanga, kuzobekwa ikhodi ye-P252C bese kuthi ukukhanya kwenjini yokuhlola, ukukhanya kwensizakalo yenjini, noma kokubili kungakhanyisa. Kwezinye izimo, i-ECM ingayivala injini futhi iyivimbele ekuqaliseni kabusha kuze kube inkinga ilungiswa futhi ikhodi isuliwe.

Inzwa yekhwalithi kawoyela:

Buyini ubunzima bale DTC?

Le khodi ibucayi futhi idinga ukunakwa ngokushesha njengoba ukuthambisa okunganele noma ingcindezi kawoyela kungadala ngokushesha okukhulu ukulimala unomphela ezintweni zenjini zangaphakathi.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenkinga ye-P252C zingafaka:

• Injini ayikwazi ukujikisa
• Ukufunda okuphansi kwengcindezi kawoyela
• Ukukhanya kwenjini yensiza kuzokhanya kungekudala
• Isibani senjini yokuhlola sivuliwe
• Umlayezo wokuhlola uwoyela kuqoqo lezinsimbi

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi ye-P252C zingafaka:

• Inzwa yekhwalithi kawoyela engaphelele
• Izinga lamafutha wenjini ephansi
• Uwoyela osezingeni eliphansi
• Izintambo ezingalungile noma ezilimele
• Isixhumi esonakalisiwe noma esonakele
• I-ECM enamaphutha

Yiziphi ezinye zezinyathelo zokuxazulula inkinga i-P252C?

Isinyathelo sokuqala sokuxazulula inkinga noma iyiphi inkinga ukubuyekeza i-Technical Service Bulletins (TSBs) yemoto ethile ngonyaka, imodeli nokutshala amandla. Kwezinye izimo, lokhu kungakongela isikhathi esiningi ngokuhamba kwesikhathi ngokukukhomba endaweni efanele.

Isinyathelo sesibili ukuhlola isimo samafutha enjini futhi uqiniseke ukuthi agcinwe ezingeni elifanele. Bese uthola zonke izakhi ezihlotshaniswa nesekhethi yenzwa yekhwalithi yamafutha enjini bese ubheka umonakalo osobala obonakalayo. Kuye ngemoto ethile, lesi sijikelezo singahlanganisa izingxenye eziningana, okuhlanganisa inzwa yekhwalithi kawoyela, amaswishi, izinkomba zokungasebenzi kahle, igeji yomfutho kawoyela, kanye neyunithi yokulawula injini. Yenza ukuhlola okujulile kokubuka ukuze uhlole izintambo ezihambisanayo ukuze uthole ukukhubazeka okusobala njengokuklwebheka, imihuzuko, izintambo eziveziwe, noma izimpawu zokusha. Okulandelayo, hlola izixhumi nezixhumi ukuze uthole ukuphepha, ukugqwala kanye nokulimala koxhumana nabo. Le nqubo kufanele ifake zonke izixhumi zikagesi nezixhumi kuzo zonke izingxenye, kuhlanganise ne-ECM. Bheka ishidi ledatha elithile lemoto ukuze uhlole ukucushwa kwesekhethi yenzwa yekhwalithi kawoyela futhi uqinisekise ingxenye ngayinye efakwe kusekethe, engafaka i-fuse noma isixhumanisi se-fusible.

Izinyathelo ezithuthukile

Izinyathelo ezengeziwe ziqondiswa kakhulu yimoto futhi zidinga ukuthi imishini efanelekile ukuthi yenziwe ngokunembile. Lezi zinqubo zidinga imultimeter yedijithali kanye nemibhalo eqondene nezobuchwepheshe eqondene nemoto.

Ukuhlolwa kwe-Voltage

Amandla wereferensi kanye nobubanzi obuvumelekile bungahluka ngokuya ngemoto ethile nokumiswa kwesekethe. Imininingwane ethile yezobuchwepheshe izobandakanya amatafula wokuxazulula inkinga nokulandelana okufanele kwezinyathelo ukukusiza wenze ukuxilongwa okunembile.

Uma le nqubo ithola ukuthi umthombo wamandla noma umhlaba ulahlekile, ukuhlolwa kokuqhubeka kungadingeka ukuhlola ubuqotho bezintambo, izixhumi, nezinye izinto. Ukuhlolwa kokuqhubeka kufanele kwenziwe njalo ngamandla angaxhunywanga kusekethe kanye nokuxhunywa kwentambo okujwayelekile nokufundwa kokuxhumeka kufanele kube ngama-0 ohms wokumelana. Ukumelana noma ukungabikho okuqhubekayo kubonisa iphutha lokuxhumeka elivulekile, elifushane, noma elonakalisiwe futhi elidinga ukulungiswa noma ukushintshwa.

Yiziphi izindlela ezijwayelekile zokulungisa le khodi?

• Ukufaka esikhundleni inzwa yekhwalithi kawoyela
• Ukuhlanza izixhumi kusuka ku-corrosion
• Lungisa noma buyisela izintambo ezingalungile
• Ushintsho lwamafutha nesihlungi
• Ukulungiswa noma ukushintshwa kwamateyipu angavumelekile
• Ukukhanya noma ukufaka esikhundleni i-ECM

Iphutha elijwayelekile

• I-ECM isetha le khodi ngemuva kokufaka inzwa yekhwalithi kawoyela wenjini ngentambo engalungile.

Ngethemba ukuthi ulwazi olukule ndatshana lusizile ukukukhomba endaweni efanele ukuxazulula inkinga yenkinga yesifunda sakho senzwa se-DTC. Le ndatshana yenzelwe ulwazi kuphela futhi imininingwane ethile yezobuchwepheshe kanye namabhulethini wensizakalo yemoto yakho kufanele kuhlale kuqala.

Udinga usizo olwengeziwe ngekhodi le-P252C?

Uma usadinga usizo nge-DTC P252C, thumela umbuzo kumazwana angezansi kwalesi sihloko.

QAPHELA. Lolu lwazi lunikezwa ngenhloso yokwaziswa kuphela. Akuhloselwe ukuthi isetshenziswe njengesincomo sokulungisa futhi asinacala nganoma yisiphi isenzo osithathayo kunoma iyiphi imoto. Yonke imininingwane ekulesi siza ivikelwe yi-copyright.
