P0352 Ukungasebenzi kahle kwesekethe eyinhloko / yesibili yekhoyili yokushisa B
Okuqukethwe
Ikhodi Yenkinga ye-OBD-II P0352 - Idatha yedatha
Ukukhubazeka Kwakhoyili B Primary / Secondary Circuit Ukungasebenzi
Isho ukuthini ikhodi yenkinga P0352?
Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezihlomele i-OBD-II. Yize kuvamile emvelweni, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli.
I-COP (coil on plug) ignition system iyona esetshenziswa ezinjinini eziningi zesimanje. Isilinda ngasinye sinekhoyili ehlukile elawulwa yi-PCM (Powertrain Control Module).
Lokhu kuqeda isidingo sezintambo ze-spark plug ngokubeka ikhoyili phezu kwe-spark plug. Ikhoyili ngayinye inezintambo ezimbili. Eyodwa amandla ebhethri, ngokuvamile asuka esikhungweni sokusabalalisa amandla. Enye intambo yi-coil driver circuitry evela ku-PCM. I-PCM isekela/inqamula le sekhethi ukuze icuphe noma ivale ikhoyili. Isekhethi yomshayeli wekhoyili igadwa yi-PCM ukuze kutholakale amaphutha.
Uma kutholakala okuvulekile noma okufushane kwisekho yomshayeli wekhoyili ongu-2, ikhodi ye-P0352 ingavela. Ngaphezu kwalokho, kuya ngemoto, i-PCM ingakhubaza futhi injektha kaphethiloli eya kusilinda.
Izimpawu
Izimpawu zekhodi yenkinga ye-P0352 zingafaka:
- Ukukhanya kwe-MIL (Isibani Sesikhombi Sokungasebenzi Kahle)
- Ukulimazeka kwenjini kungabakhona noma kube ngezikhathi ezithile
- Ukudlidliza okungavamile kungase kuzwakale lapho ungenzi lutho noma ngenkathi ushayela
- Ukulahlekelwa ukusheshisa
Izimbangela zephutha P0352
Izimbangela ezingaba khona zekhodi ye-P0352 zifaka:
- Mfushane ku-voltage noma emhlabathini kumjikelezo womshayeli we-COP
- Vula ku-COP driver circuit
- Ukuxhumeka okungalungile kukhoyili noma okhiye bokuxhuma abaphukile
- Ikhoyili engalungile (COP)
- Iphutha lokulawula ukuhamba
- Izintambo ezilimele noma ezigqwalile kubhethri yesilinda sesibili
- Ukulimala noma ukugqwala kwezintambo ezixhuma ikhoyili yesilinda sesibili kumojula yokulawula injini.
- Isekhethi evulekile noma emfushane kuhhanisi yezintambo yesiyingi sebhethri yesilinda sesibili.
- Imojuli yokulawula injini enephutha
- Iphakethe lekhoyili elingalungile
- Inhlansi, izibani zangaphambili ezinephutha
Izixazululo ezingenzeka
Ngabe injini ibhekene nokungasebenzi kahle manje? Ngaphandle kwalokho, inkinga kungenzeka ibe yesikhashana. Zama ukuzulazula futhi ubheke izintambo kwikhoyili # 2 kanye nasezintanjeni zocingo kwi-PCM. Uma ukuphambanisa izintambo kubangela ukungqubuzana ebusweni, lungisa inkinga yezintambo. Bheka ukuxhumana okungekuhle kusixhumi sekhoyili. Qiniseka ukuthi amahanisi awakhishwanga ngaphandle kwendawo noma ukujahwa. Lungisa uma kunesidingo
Uma injini ingasebenzi kahle njengamanje, misa injini bese unqamula isixhumi se- harness # 2. Bese uqala injini bese uhlola isignali yokulawula kwikhoyili # 2. Sebenzisa ubukhulu kuzokunikeza ireferensi ebonakalayo ongayibona, kepha njengoba abantu abaningi bengenakho ukufinyelela kuyo, kunendlela elula. Sebenzisa i-voltmeter esikalini se-AC hertz bese ubona ukuthi akukho yini ukufundwa ebangeni elingu-5 kuye ku-20 Hz noma kunjalo, okukhombisa ukuthi umshayeli uyasebenza. Uma kunesiginali kaHertz, shintsha ikhoyili # 2 yokushisa. Lokhu kungenzeka kubi kakhulu. Uma ungatholi noma iyiphi isignali yokuvama evela ku-PCM kusekhethi yomshayeli wekhoyili ebonisa ukuthi i-PCM iyamisa / inqamula isekethe (noma ayikho iphethini ebonakalayo esikalini uma unayo), shiya ikhoyili inqanyuliwe bese uhlola Amandla we-DC kusishayeli wesifunda kusixhumi sekhoyili yokushisa. Uma kunanoma yimaphi amandla kagesi abalulekile kulolu cingo, khona-ke kukhona okufishane kuya kwamandla kagesi kwenye indawo. Thola isifunda esifushane bese uyilungisa.
Uma kungekho voltage kumjikelezo womshayeli, cisha ukuthungela. Nqamula isixhumi se-PCM bese uhlola ubuqotho besishayeli phakathi kwe-PCM nekhoyili. Uma kungekho okuqhubekayo, lungisa isekethe evulekile noma emfushane phansi. Uma kuvulekile, hlola ukumelana phakathi komhlaba kanye nesixhumi sekhoyili sokuthungela. Kumele kube khona ukumelana okungapheli. Uma kungenjalo, lungisa okufushane kube phansi kusifunda somshayeli wamakhoyili.
QAPHELA. Uma intambo yesiginali yomshayeli wamakhoyili we-ignition ingavuleki noma ingashintshi ku-voltage noma phansi futhi ayikho isignali ye-trigger kwikhoyili, khona-ke kusolwa umshayeli wekhoyili we-PCM oyiphutha. Futhi qaphela ukuthi uma umshayeli we-PCM enesici, kungahle kube nenkinga yezintambo ebangele ukuthi i-PCM yehluleke. Kunconywa ukuthi wenze isheke elingenhla ngemuva kokufaka i-PCM ukuqinisekisa ukuthi ayiphinde yehluleke. Uma uthola ukuthi injini ayiphosi ukuthungela, ikhoyili idubula kahle, kepha i-P0352 ihlala isetha kabusha, kungenzeka ukuthi uhlelo lokuqapha ikhoyili lwe-PCM lungasebenzi kahle.
IYENZA KANJANI IKHODI YE-MCHHANIC DIAGNOSTIC P0352?
- Yenza ukuhlola amandla eqenjini elihlosiwe lamakhoyili.
- Hlola isimo sama-electrode e-spark plug.
- Ikala i-voltage ekhona kuphakethe lekhoyili
- Hlola izintambo ezixhuma kumaphakethe wekhoyili ukuthi azigugile, azigqwali, futhi ngezinye izikhathi ziyancibilika.
- Ihlola isekethe yebhethri ukuze ibekwe phansi ngendlela efanele.
- Ihlola inani eliningi lokuvuza kwe-vacuum
- Sebenzisa i-multimeter ukukala isignali ye-Hertz ethunyelwa ku-coil pack (isiza ukuhlola ukuthi i-ECM ithumela isignali efanele yini ku-coil pack)
AMAPHUTHA AVAMILE LAPHO KUHLOLWA IKHODI P0352
Abanye bangase banganaki iqiniso lokuthi ukuvuza kwe-vacuum nakho kungase kubangele le khodi. Futhi, abanye bangase badebeselele ukukala isignali ye-hertz edinga ukuthunyelwa isuka ku-ECM iye kukhoyili. Ukulinganisa isignali ye-Hertz kusiza ukuthola ukuthi imojuli yokulawula injini inephutha noma kukhona okungahambi kahle kusekethe yephakethe lekhoyili, njengokugqwala noma izintambo ezilimele.
IYIZINKANI IKHODI P0352?
Lokhu kubucayi kakhulu ngoba awukwazi ukudlula ngokusemthethweni ukuhlolwa kwemoto ngesibani se-Check Engine sivuliwe. Ukushayela i-Misfire kubi enjinini ngoba uma isilinda esisodwa sivimbekile, amanye amasilinda kuzomele asebenze kanzima ngokuphindwe kabili ukuze ajike imoto. Lokhu kuzobeka ingcindezi kwamanye amasilinda futhi kubangele ukuthi izingxenye ezifana nama-piston ring, ama-spark plug namanye ama-coil pack agqoke ngokushesha. Le khodi yaziwa ngokudala injini engalungile, okuholela ekulimaleni kwesiguquli esinamandla noma ukuxhuma uma ingalungiswanga ngokushesha ngokwanele.
YIKUPHI UKULUNGISA ONGALUNGISA IKHODI P0352?
- Ukushintsha ibhethri
- Ukushintsha ama-spark plugs
- Ukulungisa ukuvuza kwe-vacuum, okufana ne-gasket eningi evuzayo noma ulayini we-vacuum ophukile
- Ukushintsha iyunithi yokulawula injini
- Lungisa noma shintsha noma yiziphi izintambo zebhethri ezilimele.
IMIBONO ENGEZIWE UKUZE UQAPHELE IKHODI P0352
Kunconywa kakhulu ukuhlola isignali ye-Hertz kusuka ku-ECM kuya kubhethri. Kuyanconywa futhi ukuthi uhlole ukuphindaphindeka komthamo wokuvuza kwe-vacuum.
Udinga usizo olwengeziwe ngekhodi le-p0352?
Uma usadinga usizo nge-DTC P0352, 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.
