P0402 Kutaya Kwambiri Kwambiri Kutulutsa Mpweya Kumapezeka

P0402 - Kufotokozera Zaukadaulo

Kutuluka kwa gasi wotuluka mochulukira (EGR) kwapezeka.

P0402 ndi generic OBD-II kachidindo wapezeka ndi injini ulamuliro gawo (ECM) kusonyeza kuti injini utsi mpweya recirculation (EGR) valavu amalola recirculated kwambiri recirculated utsi mpweya pamene analamula kuti atsegule kudya zobwezedwa gasi kutuluka.

Kodi vuto la P0402 limatanthauza chiyani?

Izi Diagnostic Trouble Code (DTC) ndi njira yolozera, zomwe zikutanthauza kuti imagwira ntchito pamagalimoto okhala ndi OBD-II. Ngakhale zambiri, njira zina zakukonzanso zimatha kusiyanasiyana kutengera mtundu / mtundu.

EGR imayimira Kutulutsa mpweya wamafuta. Ndi gawo limodzi lamagalimoto otulutsa utsi ndipo amagwiritsidwa ntchito pochepetsa kutentha ndi kukakamiza kuyang'anira ma oxide a nitrogeni.

Nthawi zambiri, mpweya wamafuta okhathamira umakhala ndi magawo atatu: mpweya wotulutsa mpweya wotulutsa mpweya, chojambulira chopangira mphamvu ndi masensa apakati (DPF). Zinthu izi zimagwirira ntchito limodzi kuti zipereke kuchuluka koyenera kwa recirculation kutengera kutentha kwa injini, katundu, ndi zina. P0402 code zikutanthauza kuti OBD yapeza kuchuluka kwa EGR.

Zizindikiro

Mutha kuwona zovuta pakusamalira, mwachitsanzo, injini imatha kulephera kugwira ntchito. Pakhoza kukhala zizindikilo zina.

• Kuunikira kwa Check Engine kudzayatsidwa ndipo codeyo idzasungidwa mu ECM.
• Injini ikhoza kuyenda movutirapo ngati valavu yakanikira pamalo otseguka.
• Dongosolo la EGR la injini litha kukhala ndi kutayikira kwamagetsi pa sensa yakumbuyo yakumbuyo.

Zifukwa za P0402 kodi

Khodi ya P0402 imatha kutanthauza kuti chimodzi kapena zingapo mwazimene zachitika:

• Chojambulira cha DPFE (Differential Pressure) ndicholakwika ndipo chimafunika kusinthidwa.
• Kutulutsa mpweya wamafuta kumadzaza (makamaka kumanga kwa kaboni).
• Utsi mpweya recirculation vavu zosalongosoka
• Mpweya wotsekemera wa mpweya sungatseguke chifukwa cha kusowa kwa mpweya.

Mayankho otheka

Pankhani ya P0402, anthu nthawi zambiri amalowetsa valve ya EGR, koma vuto limabwereranso. Yankho lotheka kwambiri ndikusintha sensa ya DPFE.

• Fufuzani magetsi pa sensa ya DPFE onse osagwira komanso otseguka EGR.
• Sinthani sensa ya DPFE.

Ma Code a EGR Ogwirizana: P0400, P0401, P0403, P0404, P0405, P0406, P0407, P0408, P0409

KODI MACHHANIC DIAGNOSTIC KODI P0402 Imatani?

• Kusanthula deta kumayimitsa ma code frame ndi zikalata kutsimikizira vuto.
• Imachotsa ma code a injini ndi ETC ndi kuyesa kwa msewu kuti muwone ngati khodiyo ibwerera.
• Yang'anani mowoneka bwino ma hoses a vacuum, ma wiring, kulumikizana ndi valavu ya EGR ndikuwongolera solenoid, ndi sensa ya kutentha kwa EGR ndi sensa yakumbuyo yakumbuyo.
• Imalepheretsa ndikuyesa ngati EGR vacuum vacuum ingagwiritsidwe ntchito pa valavu pamene solenoid yolamulira imatsegulidwa pa kuwala kuti ikhale yothamanga, osati yotseguka.
• Imayang'ana chosinthira chothandizira kuti chiwonongeke kapena kupanikizika kwambiri kumbuyo mu dongosolo la EGR.
• Imachotsa valavu ya EGR ndi sensa ya kutentha kuti muwone ngati kaboni ikugwira valavu ya EGR yotseguka ndipo kaboni ikulepheretsa doko la EGR purge, kuteteza valavu kuti isatuluke mu vacuum.

ZOPHUNZITSA ZAMBIRI PAMENE AMADZIWA KODI P0402

• Bwezerani valavu ya EGR popanda kuyang'ana mphamvu ya EGR kuti muwonetsetse kuti ikhoza kulamulira kutsegula kwa valve ya EGR.
• Musayang'ane ngati valavu ya EGR ikugwiridwa ndi malasha otseguka mwamakina musanalowe m'malo mwake.

KODI P0402 NDI YOYAMBA BWANJI?

• Kuchulukanso kwa gasi kumapangitsa kuti injini igwedezeke kapena kuyimitsidwa pothamanga, kapena kupangitsa injiniyo kuti ikhale yovuta kwambiri.
• Kuunikira kwa Check Engine kokhazikitsidwa kumapangitsa galimotoyo kulephera kuyesa kutulutsa mpweya.
• Ngati chosinthira chothandizira chatsekedwa ndikuyambitsa nambalayo, zitha kuchititsa kuti mphamvu kapena injini iyambe kutha.

KODI KUKONZA KODI KUUNGAKONZE KODI P0402)?

• Kusintha valavu yotseguka ya EGR
• Kusintha chosinthira chothandizira chosweka
• Kusintha sensor kutentha kwa EGR kapena kuyeretsa kuchokera ku ma depositi a kaboni kuti mukonze ngati ilembetsa kusintha kwa kutentha kwambiri.
• EGR Back Pressure Control Valve Replacement

ZOWONJEZERA ZOWONJEZERA KUDZIWA KODI P0402

Code P0402 imayambika pamene EGR sensor sensor imazindikira kusintha kwakukulu kwa kutentha kuposa momwe EGR idalamula kuti itsegule. Izi nthawi zambiri zimayamba chifukwa cha EGR backpressure control valve diaphragm ikuwomberedwa pakapita nthawi ndi utsi wobwerera kumbuyo kapena chothandizira chotsekedwa pang'ono.

Mukufuna thandizo lina ndi nambala yanu ya p0402?

Ngati mukufunabe thandizo ndi DTC P0402, lembani funso mu ndemanga pansipa pamutuwu.

ZINDIKIRANI. Izi zimaperekedwa kuti zidziwitse zokha. Sikuti tizigwiritsa ntchito ngati malingaliro okonzanso ndipo sitili ndi udindo pazomwe mungachite pagalimoto iliyonse. Zomwe zili patsamba lino ndizotetezedwa ndi zovomerezeka.
