P0400 Kutulutsa Mpweya Woyendetsa Kutaya Kutayika

Khodi Yovuta ya OBD-II - P0400 - Kufotokozera Zaukadaulo

P0400 - Kusokonekera kwa dongosolo la exhaust gas recirculation (EGR).

Kodi vuto la P0400 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.

Valavu ya Exhaust Gas Recirculation (EGR) ndi valavu yomwe imagwiritsa ntchito mpweya womwe umayambiranso kutentha kwa mpweya.

Modulerain control module (PCM) imatsimikizira kufunikira kutengera kuchuluka kwa injini, kutentha, ndi zina. Ngati PCM itazindikira kuti kuchuluka kwa mpweya wokwanira wolowa mu silindayo kunali kosakwanira kapena kulibe, nambala iyi yakhazikitsidwa.

Zizindikiro

Woyendetsa sangazindikire zina zilizonse kupatula MIL (Kuwala Koyendetsa Chizindikiro). Komabe, zizindikilo zobisika zidzawonjezera kutentha kwamoto komanso kuwonjezeka kwa mpweya wa NOx.

• Yatsani chenjezo la injini pa bolodi.
• Kuwonjezeka kwa mpweya wa NOx komanso kuwonjezeka kwa kutentha kwa moto.
• Kugwedezeka kotheka kwa injini.

Zifukwa za P0400 kodi

Khodi ya P0400 itha kutanthauza kuti chimodzi kapena zingapo mwazimene zachitika:

• Odzaza utsi mpweya recirculation ritsa, amene kulepheretsa otaya mpweya utsi.
• Utsi recirculation solenoid zosalongosoka
• Zolakwitsa utsi mpweya recirculation solenoid vavu vavu Kulumikizana / mangani
• Mizere yopuma imawonongeka / sinadulidwe kuchokera pamagetsi a EGR kapena pa valve ya EGR.
• Utsi mpweya recirculation vavu zosalongosoka
• Vavu ya EGR yowonongeka kapena yosalongosoka. Valve ya EGR ikhoza kumamatira kapena kutsekedwa.
• Zolakwika kapena zowonongeka za EGR sensor sensor ndi mabwalo.
• Tsegulani kapena lalifupi mu EGR valve wiring harness.
• Kusagwirizana kwamagetsi ku valavu ya EGR.
• Ndime ya EGR yatsekedwa, kuletsa kutuluka kwa mpweya wotulutsa mpweya.
• Ma hoses owonongeka kapena osalumikizidwa kuchokera ku EGR valve solenoid.

Mayankho otheka

Popeza mapangidwe amagetsi otulutsa mpweya amasiyana, kuyesa kokha sikungakhale kokwanira:

• Pogwiritsa ntchito chida chosakira, gwiritsani ntchito valavu ya EGR pomwe injini ikuyenda. Ngati injini ikupunthwa, vutoli limakhala kulephera kwa zingwe kapenanso kutsekereza kwapakatikati.
• Ngati injini sikuphunthwa, gwiritsani ntchito valavu ya EGR pamanja ngati kungatheke. Pokhapokha ngati injini ikudumphira kapena malo ogulitsira, madoko amakhala otsekedwa. Kuchotsa mavavu ndikuyeretsa madoko onse kudzafunika.
• Kuyesa kwa solenoid kumangogwiritsidwa ntchito ndi chida chowunikira chifukwa ma solenoid ambiri amakhala ndi magetsi ozungulira m'malo mowirikiza.
• Onani mizere yonse yazitsulo, zotsekemera, ndi zina zambiri.
• Yendani ndi zingwe za solenoid ndi solenoid kuti iwonongeke.
• Sinthanitsani valavu yowotchera mpweya.

Ma Code a EGR Ogwirizana: P0401, P0402, P0403, P0404, P0405, P0406, P0407, P0408, P0409

Zolakwa Zomwe Zimachitika Mukamazindikira Khodi P0400

• Kusintha valavu ya EGR musanayang'ane ma depositi a kaboni pa sensa ya kutentha kwa EGR.
• Kusintha valavu ya EGR popanda kuyang'ana mphamvu ya EGR.

Kodi P0400 ndi yowopsa bwanji?

• Valavu ya EGR yolakwika imatha kuyambitsa injini kuyaka mopitilira muyeso, zomwe zitha kuwononga mkati mwa pistoni ya injini ndi ma valve.
• Kuwala kwa injini yowunikira kumapangitsa galimotoyo kulephera kuyesa mpweya chifukwa cha NOx yochulukirapo.

Ndi kukonza kotani komwe kungakonze P0400?

• Kusintha kwa valve ya USR
• Kusintha mzere wosweka wosweka ku valavu ya EGR
• Kusintha sensor kutentha kwa EGR kapena kuyeretsa kuchokera ku mwaye kuti mukonze
• Kuchotsa ma depositi a kaboni kuchokera ku mapaipi a EGR kupita kumalo ochulukirapo

Ndemanga zowonjezera zomwe muyenera kuziganizira ponena za code P0400

Code P0400 imayambika pamene EGR sensor sensor sikuwona kusintha kwa kutentha pamene EGR ikulamulidwa kuti itsegule. Masensa awa amakonda kudziunjikira mpweya wambiri, zomwe zimawapangitsa kukhala osamva kutentha kuchokera ku mpweya wa EGR.

Mukufuna thandizo lina ndi nambala yanu ya p0400?

Ngati mukufunabe thandizo ndi DTC P0400, 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.
