P245B Kutulutsa Mpweya Wozizira Wozizira Wodutsa Panjinga / Magwiridwe

Mapepala a OBD-II DTC

EGR Wozizira Kulambalala Dera Kuchokera M'njira / Magwiridwe

Kodi izi zikutanthauzanji?

Iyi ndi generic Powertrain Diagnostic Trouble Code (DTC) yogwiritsidwa ntchito pamagalimoto ambiri a OBD-II (1996 ndi atsopano). Izi zitha kuphatikizira, koma sizingokhala mu, Ford, Dodge, Ram, Jeep, Chevrolet, Volkswagen, Mercedes, ndi zina zambiri. Ngakhale zili choncho, njira zowongolera zenizeni zimatha kusiyanasiyana kutengera mtundu wachitsanzo, kupanga, mtundu ndi kapangidwe kake. ...

Khodi yovuta ya OBD-II P245B ndi ma P245A, P245C, ndi P245D omwe amagwirizana nawo amalumikizidwa ndi dera lozizira la EGR.

Cholinga cha gawo loyendetsa bwino la EGR ndikutsegula ndi kutseka valavu yolumpha ya EGR pansi pazomwe zidakonzedweratu kuti zisawonongeke kuzizira kwa EGR, kotchedwa plugging, komwe kumakhudza magwiridwe antchito a injini ya dizilo. Gawo loyang'anira injini (ECM) limayang'anira dera lino polandila zofufuzira kuchokera pachosinthira kutentha kwa EGR ndi zinthu zina zogwirizana kuti ziwongolere valavu yozizira ya EGR, yomwe imabwezeretsa mpweya wakutentha pakuwotcha kwamitundu yambiri. Malo a valavu ya EGR, ozizira a EGR, chosinthira kutentha ndi zinthu zina zogwirizana zimasiyanasiyana kuchokera pagalimoto kupita pagalimoto ndipo zimasiyanasiyana kwambiri kuchokera pakupanga mpaka kupanga.

ECM ikazindikira mphamvu yachilendo kapena kukana kunja kwa magwiridwe anthawi zonse omwe akuyembekezeredwa pa EGR yozizira yoyendetsera dera, nambala ya P245B imakhazikika ndikuwunika kwa injini, kuwala kwa injini, kapena magetsi onse awiri.

Chitsanzo EGR ozizira kulambalala valavu:

Kodi kuuma kwa DTC kumeneku ndi kotani?

Kukula kwa code iyi kumatha kusiyanasiyana kuchokera pakatikati mpaka povuta, kutengera zizindikilo zavutoli komanso mulingo wa chiller ndikudutsa magwiridwe antchito. Valavu ya EGR yolakwika kapena yoyendetsa dera ingayambitse kuyatsa kwambiri ndikuwotchera injini, komwe kumatha kuwononga ma pistoni, mavavu, ndi zida zina zama injini zamkati.

Kodi zina mwazizindikiro za code ndi ziti?

Zizindikiro za vuto la P245B zitha kuphatikizira izi:

• Injini Imatha Kulephera Kutulutsa Mpweya
• Kuyatsira kulira kapena kugogoda mukamathamanga
• Kuchuluka mafuta
• Kugwiritsa ntchito injini molakwika
• Kuunika kwa injini yakutsegulira kudzafika posachedwa
• Chowunikira cha injini chikuyatsa

Kodi zina mwazomwe zimayambitsa codezi ndi ziti?

Zifukwa za code iyi ya P245B zitha kuphatikizira izi:

• Utsi recirculation ozizira kuzilambalala vavu zosalongosoka
• Yotsekeka kapena kuonongeka utsi recirculation ozizira
• Kutentha kusinthasintha
• Kuchulukitsa kaboni
• Kulumikizana kolakwika kapena kowonongeka
• Zowonongeka, zowonongeka kapena zotayirira
• ECM yolakwika

Kodi ndi njira ziti zina zothetsera P245B?

Gawo loyamba pothetsera vuto lililonse ndikuwunikanso za Technical Service Bulletins (TSBs) zamagalimoto pachaka, mtundu, ndi kupangira magetsi. Nthawi zina, izi zimatha kukupulumutsirani nthawi yayitali ndikukulozerani njira yoyenera.

Gawo lachiwiri ndikupeza zigawo zonse zomwe zimagwirizanitsidwa ndi dera lozizira la EGR ndikuwunika kuti liwone kuwonongeka kwakuthupi. Malingana ndi galimoto yeniyeni, derali likhoza kukhala ndi zigawo zingapo, kuphatikizapo kusintha kwa kutentha, valavu yodutsa, EGR valve, EGR cooler, ndi unit control unit. Yang'anani mozama kuti muwone mawaya omwe akugwirizana nawo kuti muwone zolakwika zoonekeratu monga zokwapula, zotupa, mawaya owonekera, kapena zipsera. Kenako, yang'anani zolumikizira ndi maulumikizidwe kuti chitetezo, dzimbiri ndi kuwonongeka kwa ojambula. Njirayi iyenera kuphatikizira kulumikizana kwa ma waya kuzinthu zonse kuphatikiza kusintha kwa kutentha kwa EGR ndi gawo lowongolera injini. Yang'anani pa pepala la deta la galimoto kuti muwone makonzedwe a EGR bypass valve control circuit ndi kutsimikizira chigawo chilichonse chomwe chikuphatikizidwa mu dera, zomwe zingaphatikizepo fuse kapena fusible link muzinthu zina.

Njira zapamwamba

Njira zowonjezerazo zimakhala zenizeni zagalimoto ndipo zimafuna zida zoyenerera kuti zichitike molondola. Njirazi zimafuna zikwangwani zama digito zama multimeter komanso zamagalimoto.

Mayeso amagetsi

Ma voliyumu ofotokozera ndi magulu ololeka amatha kusiyanasiyana kutengera mtundu wamagalimoto ndi kasinthidwe ka dera. Dongosolo lenileni laumisiri liphatikizira matebulo othetsera mavuto ndi njira zoyenera kukuthandizani kudziwa molondola.

Izi zikazindikira kuti magetsi kapena nthaka ikusowa, kuyeserera kopitilira muyeso kungafunike kuti mutsimikizire kukhulupirika kwa zingwe, zolumikizira, ndi zinthu zina. Kuyesa kopitilira muyeso kumayenera kuchitika nthawi zonse ndi mphamvu yolumikizidwa kudera ndikuwerengedwa koyenera kwa zingwe ndi kulumikizana kuyenera kukhala 0 ohms of resistance. Kukaniza kapena kusapitilira kwina kumawonetsa cholakwika cha waya chomwe chimatsegulidwa, kuchepetsedwa, kapena kuwonongeka ndipo chikufunika kukonzedwa kapena kusinthidwa.

Kodi njira zokhazikika zotani zokonzera code iyi ndi ziti?

• Kusintha utsi recirculation wozizira
• Kusintha valavu yozizira ya EGR
• Kuchotsa chosinthira kutentha
• Kukonza zolumikizira ndi dzimbiri
• Konzani kapena sinthanitsani zingwe zolakwika
• Kukonza kaboni
• Kuwala kapena kusintha ECM

Vuto lalikulu

• Kusintha valavu yozizira yozizira ya EGR pakumanga kaboni kapena kulumikizana kolakwika kumapangitsa ECM kukhazikitsa nambala iyi.

Tikukhulupirira kuti zambiri zomwe zatchulidwa m'nkhaniyi zakuthandizani kukulozerani njira yabwino yothetsera vuto lozizira la EGR podutsa gawo loyendetsa DTC. Nkhaniyi ndi yongofuna kudziwa zambiri komanso ma data aukadaulo a galimoto yanu ayenera kukhala patsogolo nthawi zonse.

Zokambirana zokhudzana ndi DTC

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

Mukufuna thandizo lina ndi nambala ya P245B?

Ngati mukufunabe thandizo ndi DTC P245B, 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.
