P0402 Ukugeleza Kokushiswa Kwegesi Okukhulu Kakhulu Kutholakele

I-P0402 - Incazelo Yobuchwepheshe

Kutholwe ukugeleza kwe-exhaust gas recirculation (EGR) eyeqile.

I-P0402 iyikhodi evamile ye-OBD-II etholwe yimojula yokulawula injini (ECM) ebonisa ukuthi i-valve ye-exhaust gas recirculation (EGR) ivumela igesi ekhipha umoya ekhishwa kabusha eningi kakhulu uma iyalwa ukuthi ivule ukugeleza kwegesi ehlukahlukene.

Isho ukuthini ikhodi yenkinga P0402?

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-EGR imele ukukhishwa kwegesi ye-Exhaust. Kuyingxenye yohlelo lokukhipha imoto futhi kusetshenziselwa ukunciphisa ukushisa komlilo nengcindezi ukulawula i-nitrogen oxides.

Imvamisa, uhlelo lokukhishwa kabusha kwegesi lokukhipha luqukethe izingxenye ezintathu: i-valve yokukhipha igesi, i-actuator solenoid kanye ne-differential sensor sensor (DPF). Lezi zinto zisebenza ngokubambisana ukuhlinzeka inani elifanele lokuphindwaphindwa kabusha kususelwa ekushiseni kwenjini, umthwalo, njll. Ikhodi ye-P0402 isho ukuthi i-OBD ithole inani elidlulele le-EGR.

Izimpawu

Ungaqaphela izinkinga ngokuphatha, isibonelo, injini ingahluleka lapho idling. Kungaba nezinye izimpawu futhi.

• Ukukhanya Kwenjini Yokuhlola kuzokhanya futhi ikhodi izogcinwa ku-ECM.
• Injini ingase isebenze kabi uma i-valve ibambeke endaweni evulekile.
• Isistimu ye-EGR yenjini ingaba nokuvuza kwe-exhaust kunzwa yokucindezela kwangemuva.

Izimbangela zephutha P0402

Ikhodi ye-P0402 kungenzeka isho ukuthi umcimbi owodwa noma eminingi yenzekile:

• Inzwa ye-DPFE (Differential Pressure) ayisebenzi kahle futhi idinga ukushintshwa.
• Ukukhishwa kwegesi yokukhipha kuvimbekile (cishe ukwakhiwa kwekhabhoni).
• Exhaust igesi recirculation valve kungalungile
• Iveluvu yokukhipha igesi yokukhipha kungenzeka ingavuleki ngenxa yokungabi nalutho.

Izixazululo ezingenzeka

Endabeni ye-P0402, abantu ngokuvamile bashintsha i-valve ye-EGR, kodwa inkinga ibuya. Isixazululo esingenzeka kakhulu ukufaka esikhundleni senzwa ye-DPFE.

• Bheka i-voltage kuzinzwa ze-DPFE kuzo zombili i-idle nevulekile ye-EGR.
• Miselela inzwa ye-DPFE.

Amakhodi E-EGR Ahlanganisiwe: P0400, P0401, P0403, P0404, P0405, P0406, P0407, P0408, P0409

IYENZA KANJANI IKHODI YE-MCHHANIC DIAGNOSTIC P0402?

• Iskena idatha imisa amakhodi ozimele namadokhumenti ukuze kuqinisekiswe inkinga.
• Isula amakhodi enjini nawe-ETC nokuhlolwa komgwaqo ukuze kubonakale ukuthi ikhodi iyabuya yini.
• Hlola ngokubonakalayo amapayipi evacuum, izintambo, ukuxhumana kwe-valve ye-EGR nokulawula i-solenoid, kanye nenzwa yezinga lokushisa ye-EGR nenzwa yokucindezela emuva.
• Ikhubaza futhi ihlole uma ivacuum ye-EGR valve ingasetshenziswa kuvalvu lapho i-solenoid yokulawula ivuleka ekukhanyeni kuya ekusheshiseni okumaphakathi, hhayi nje ukuvula ngokugcwele.
• Ihlola isiguquli se-catalytic ngomonakalo noma ingcindezi engemuva eyeqile kusistimu ye-EGR.
• Ikhipha i-valve ye-EGR nenzwa yezinga lokushisa ukuze ihlole ukuthi ingabe ikhabhoni ibambe i-valve ye-EGR ivuliwe futhi ikhabhoni ivimbe imbobo yokuhlanza i-EGR, ivimbela ivalvu ukuthi ingaphumi ku-vacuum.

AMAPHUTHA AVAMILE LAPHO KUHLOLWA IKHODI P0402

• Shintsha i-valve ye-EGR ngaphandle kokuhlola inzwa yokucindezela kwe-EGR ukuze uqiniseke ukuthi ingakwazi ukulawula ukuvulwa kwe-valve ye-EGR.
• Ungahloli ukuthi i-valve ye-EGR ibanjwe yini ucezu lwamalahle oluvuleke ngomshini ngaphambi kokuyishintsha.

IYIZINKANI IKHODI P0402?

• Ukuzungeza kabusha kwegesi okugeleza kakhulu kungabangela injini ukuba inyakaze noma ime lapho isheshisa, noma kubangele injini ukuba ingasebenzi ibe nzima kakhulu.
• Isibani se-Check Engine esicushiwe sizobangela imoto ukuthi yehlule uhlolo lokukhishwa kwekhabhoni.
• Uma isiguquli se-catalytic sivinjiwe esibangela ikhodi, singaholela ekulahlekelweni kwamandla noma injini eqalayo.

YIKUPHI UKULUNGISA ONGALUNGISA IKHODI P0402?

• Ukushintsha i-valve ye-EGR ebambekile evuliwe
• Ukushintsha isiguquli se-catalytic esiphukile
• Ukushintsha inzwa yezinga lokushisa ye-EGR noma ukuyihlanza kusukela kumadiphozithi ekhabhoni ukuze uyilungise uma ibhalisa ukushintsha okukhulu kwezinga lokushisa.
• I-EGR Back Pressure Control Valve Replacement

IMIBONO ENGEZIWE UKUZE UQAPHELE IKHODI P0402

Ikhodi P0402 iqaliswa lapho inzwa yezinga lokushisa ye-EGR ithola uguquko olukhulu lwezinga lokushisa kune-EGR eyalwe ukuba luyivule. Lokhu ngokuvamile kubangelwa i-EGR backpressure control valve diaphragm eshaywa ngokuhamba kwesikhathi ukucindezela kwe-exhaust backpressure noma i-catalyst evinjwe kancane.

Udinga usizo olwengeziwe ngekhodi le-p0402?

Uma usadinga usizo nge-DTC P0402, 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.
