P2426 Chizindikiro chotsika cha mayendedwe olamulira a valavu yozizira yamafuta okonzanso gasi

Mapepala a OBD-II DTC

Mulingo wazizindikiro wotsika mu gawo lolamulira la valavu yozizira yamafuta oyimitsira mpweya

Kodi izi zikutanthauzanji?

Code Yovutikira Ndi Kuzindikira (DTC) ndi nambala yofalitsira ndipo imagwira ntchito pamagalimoto ambiri a OBD-II (1996 ndi atsopano). Izi zitha kuphatikizira, koma sizingokhala mu, VW, Nissan, Audi, Ford, ndi zina zambiri. Ngakhale zili choncho, njira zowongolera zenizeni zimatha kusiyanasiyana kutengera mtundu wachitsanzo, kapangidwe, kapangidwe kake ndi kasinthidwe kake.

Khodi yosungidwa P2426 imatanthauza kuti gawo loyendetsa mphamvu yamagetsi (PCM) lapeza mphamvu yamagetsi yosakwanira mu gawo loyendetsa ma valve la EGR. Machitidwe ozizira a EGR amangogwiritsidwa ntchito mu injini za dizilo.

Dongosolo la EGR lakonzedwa kuti libweretse ena mwa mpweya wotulutsa utsi kubwereranso ku makina opangira injini, komwe umalowetsa m'malo mpweya wabwino wokhala ndi mpweya wabwino. Kubwezeretsa utsi wamafuta ndi mpweya wokhala ndi mpweya wabwino kumachepetsa kuchuluka kwa ma nitrojeni oxide (NOx). NOx imayendetsedwa ndi malamulo aboma ndipo ndi imodzi mwazomwe zimayambitsa mpweya wozimitsa mpweya wa ozoni.

Machitidwe ozizira a EGR amagwiritsidwa ntchito pochepetsa kutentha kwa mpweya wa EGR asanalowe mu injini yolowetsa mpweya. Dongosolo lozizira la EGR limagwira ngati radiator kapena pachimake pa heater. Choziziritsira injini chimasindikizidwa mkati mwa malo omata omwe adayikidwa kuti alole mpweya wa EGR kuti udutse. Wopopera wozizira nthawi zina amagwiritsidwanso ntchito. Valavu yozizira yamagetsi yolamulidwa ndi zamagetsi imayendetsa mayendedwe ozizira a injini kupita ku EGR yozizira pamikhalidwe ina.

PCM imagwiritsa ntchito zolowetsa kuchokera ku makina ozizira otenthetsera injini (ECT) ndi EGR ozizira kutentha masensa / s kuti adziwe kuti ndi liti pomwe valavu yozizira ya EGR imatsegulira kapena kutseka nthawi iliyonse. PCM imayang'anira ma voliyumu ku makina olamulira a EGR ozizira nthawi iliyonse kiyi ikatsegulidwa.

Mawonekedwe ozizira a EGR ndi masensa ozizira otentha a EGR amadziwitsa PCM zosintha mu EGR yozizira komanso kutentha kwa injini. PCM imayerekezera zolowererazi kuti ziwerengere ngati makina ozizira a EGR akugwira bwino ntchito. Kutulutsa mpweya wamafuta oyatsira kutentha nthawi zambiri kumakhala pafupi ndi valavu yotulutsa mpweya, pomwe masensa a ECT nthawi zambiri amakhala mu jekete yamadzi yamphamvu kapena jekete yamadzi yambiri.

Ngati magetsi oyendetsa magetsi a EGR ndi otsika kwambiri, pansi pamtundu woyenera, kapena ngati zolowera ku EGR sensor sensor / sensors sizofanana ndi zomwe zimachokera ku ECT sensa, P2426 idzasungidwa ndipo nyali yowunikira itha kuwunikiridwa .

Mpweya utsi recirculation valavu ndi gawo la utsi dongosolo mpweya recirculation:

Kodi kuuma kwa DTC kumeneku ndi kotani?

Khodi yosungidwa P2426 imanena za dongosolo la EGR. Sayenera kukhala m'gulu lolemera.

Kodi zina mwazizindikiro za code ndi ziti?

Zizindikiro za vuto la P2426 zitha kuphatikiza:

• Palibe zizindikiro (kupatula kusunga nambala)
• Kuchuluka kwa kutentha kwamphamvu
• Kuchepetsa mafuta
• Utsi Mpweya Kutentha SENSOR zizindikiro
• Zizindikiro za kutentha kwa injini

Kodi zina mwazomwe zimayambitsa codezi ndi ziti?

Zifukwa za code iyi zitha kuphatikizira izi:

• Tsegulani kapena zazifupi mu waya kapena zolumikizira kuti muwongolere mpweya wotulutsa mpweya wozizira
• Mulingo wozizira wotsika wa injini
• Zowonongeka / zotenthetsera kutentha kwa mpweya wamagetsi
• Utsi recirculation wozizira ozizira
• Kutentha kwa injini
• Utsi mpweya recirculation kuzirala zimakupiza zosalongosoka

Kodi ndi njira ziti zina zothetsera P2426?

Makina oziziritsa injini ayenera kudzazidwa pamlingo woyenera ndi chozizira choyenera musanapite. Ngati pali injini zoziziritsa moto kapena injini ikamatenthedwa, iyenera kukonzedwa musanapitirize kudziwa kuti P2426 yasungidwa.

Makina owunikira, digito volt/ohmmeter, gwero lazidziwitso zamagalimoto, ndi thermometer ya infrared (yokhala ndi laser pointer) ndi zina mwa zida zomwe ndingagwiritse ntchito pozindikira P2426.

Ndikhoza kuyamba poyang'ana mwachidwi mawaya ndi zolumikizira zogwirizana ndi kachipangizo kotentha ka EGR ndi sensa ya ECT. Zingwe zomwe zili pafupi kwambiri ndi mapaipi otentha otentha ndi malo ochulukirapo ziyenera kuwunikidwa mosamala.

Lumikizani chojambulira pa doko lodziwitsa magalimoto ndikupeza ma code onse osungidwa ndi chimango chazomwe zimayimitsidwa. Ndisanachotse ma code ndikuyesa galimotoyi, ndikufuna kuti ndilembe zidziwitsozi ngati zingadzakhale zodukiza.

Pakadali pano, chimodzi mwazinthu ziwiri zichitike: PCM ipita modikirira (palibe manambala omwe asungidwa), kapena P2426 idzayeretsedwa.

PCM ikakhala yokonzeka, P2426 ndiyosakhazikika ndipo imavuta kuyipeza. Nthaŵi zambiri, vutoli liyenera kukulirakulira asanadziwe bwinobwino.

Ngati P2426 yakhazikitsidwanso, gwiritsani ntchito sikani yosanja kuti muwone momwe kachipangizo ka EGR kachipangizo kamatchulira komanso kachipangizo ka ECT. Kuchepetsa kutsata kwa sikani kuti muphatikize zokhazokha zomwe zingayambitse kuyankha kwachangu. Ngati sikani ikuwonetsa kuti kutentha kwa EGR ndi ECT kuli m'njira zovomerezeka, kukayikira PCM yolakwika kapena pulogalamu yolakwika ya PCM. Izi sizomwe mungachite.

Ngati EGR kutentha sensa ya data kapena yozizira ya sensa ya kutentha imakhala yosakhazikika kapena yopanda malongosoledwe, yesani sensa / masensa omwewo potsatira njira zoyeserera ndi malongosoledwe omwe amaperekedwa pagalimoto yanu. Zosintha zomwe sizikugwirizana ndi zomwe wopanga akuyenera kuziona ngati zopanda pake.

Gwiritsani ntchito DVOM kuyesa gawo loyendetsa ma valve ozizira la EGR ngati masensa akugwira ntchito bwino. Kumbukirani kuzimitsa owongolera onse asanayesedwe. Konzani kapena sinthani ma circuits otseguka kapena afupikitsa ngati kuli kofunikira.

Ngati maseketi onse amagetsi a EGR ali olimba, gwiritsani ntchito infrared thermometer kuti muwone kutentha kwa mpweya wa utsi pamalo olowera ozizira a EGR (valavu) komanso potulutsa chozizira cha EGR (ndi injini yomwe ikuyenda komanso mwachizolowezi kutentha kutentha). Yerekezerani zotsatira ndi zomwe wopanga akuchita ndikusintha zinthu zilizonse zolakwika za EGR ngati kuli kofunikira.

• Kukhazikitsa aftermarket komanso magwiridwe antchito oyendetsera bwino mpweya kutha kubweretsa kusungidwa kwa P2426.

Zokambirana zokhudzana ndi DTC

• Pakadali pano palibe mitu yofananira m'mabwalo athu. Tumizani mutu watsopano pamsonkhano tsopano.

Mukufuna thandizo lina ndi code P2426?

Ngati mukufunabe thandizo ndi DTC P2426, 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.
