P049E EGR B Udindo Wapamwamba Kupitilira Malire Ophunzirira

Mapepala a OBD-II DTC

Kutulutsa Mpweya Wotsitsimula Gasi B Kupitilira Malire Ophunzitsira

Kodi izi zikutanthauzanji?

Imeneyi ndi nambala yovutikira yotengera matenda (DTC) ndipo imagwiritsidwa ntchito kwambiri pamagalimoto a OBD-II omwe ali ndi Exhaust Gas Recirculation (EGR) system. Izi zitha kuphatikizira, koma sikuchepera, magalimoto ochokera ku Dodge / Ram (Cummins), Chevy / GMC (Duramax), Honda, Jeep, Hyundai, ndi zina zambiri.

Ngakhale ndizazonse, njira zowongolera zenizeni zimatha kusiyanasiyana kutengera mtundu wachitsanzo, kapangidwe, kapangidwe kake, ndi kasinthidwe kakutumizirana.

Ngati galimoto yanu yokhala ndi OBD-II yasunga nambala ya P049E, zikutanthauza kuti powertrain control module (PCM) yawona kuti ikuwonongeka panjira yoyeserera ya valavu yotsika ya mpweya (EGR). B amatanthauza malo ena ake a valavu ya EGR.

Makina oyendetsa gasi otsika otulutsa utsi apangidwa kuti azidyetsa gawo lina la mpweya wamafuta kubwerera muzowonjezera zochulukirapo kuti athe kuwotchedwanso kachiwiri. Izi ndizofunikira pochepetsa kuchuluka kwa ma nitrous oxide (NOx) tinthu tomwe timatulutsidwa mumlengalenga ngati zotsatira zoyaka moto wamkati ndi injini ya dizilo. NOx amakhulupirira kuti ndi amene amathandizira kuti ozoni asawonongeke chifukwa chotulutsa mpweya. Kutulutsa kwa NOx kuchokera kumagalimoto ku North America kumatsata malamulo aboma.

Malire ophunzirira ndi digiri yokhazikika yomwe imawonetsa magawo ochepera komanso apamwamba kwambiri omwe malo ena (B) a valavu yotsika ya EGR amatha kusintha. Ngati PCM ikuwona kuti malo enieni a EGR valve ali kunja kwa magawowa, code ya P049E idzasungidwa ndipo nyali yowonetsera zolakwika (MIL) ikhoza kubwera. M'magalimoto ena, zimatengera maulendo angapo oyatsa (polephera) kuyambitsa MIL.

Kodi kuuma kwa DTC kumeneku ndi kotani?

Popeza nambala ya P049E ndiyokhudzana ndi dongosolo la EGR, sayenera kuonedwa ngati yayikulu.

Kodi zina mwazizindikiro za code ndi ziti?

Zizindikiro za vuto la P049E zitha kuphatikizira izi:

• Zowonjezera, sipadzakhala zizindikiro ndi code iyi.
• Kuchepetsa mafuta pang'ono
• Zotheka kuthana ndi mavuto

Kodi zina mwazomwe zimayambitsa codezi ndi ziti?

Zifukwa zamakhodi awa a P049E EGR atha kuphatikiza:

• Opunduka utsi vavu recirculation vavu
• Utsi mpweya recirculation kachipangizo zosalongosoka
• Zolakwika za PCM kapena PCM zolakwika

Kodi ndi njira ziti zina zothetsera P049E?

Nthawi zambiri ndimayamba kupeza matenda anga ndikupeza cholumikizira chagalimoto ndikupeza ma nambala onse osungidwa ndi zambiri zofananira. Nditha kulemba zonsezi ndikamazifuna ndikamapeza matenda anga. Kenako ndimayesa kuyendetsa galimoto kuti ndiwone ngati nambala yokhayo yasintha nthawi yomweyo.

Pofufuza za Vehicle Technical Service Bulletins (TSB) zolembera zomwe zikufanana ndi galimoto, ma code omwe adasungidwa, ndikuwonetsa zisonyezo, mutha kupeza yankho la matenda anu (omwe angakhale ovuta). Popeza marekodi a TSB amachokera kwa akatswiri masauzande ambiri, nthawi zambiri amakhala ndi mfundo zothandiza kwambiri.

Ngati P049E ikasungidwa ndikachotsa ma code, ndidzakhala ndi mwayi wopeza ma scanner, a digital volt / ohmmeter (DVOM), komanso gwero lodalirika lazidziwitso zamagalimoto.

Tsopano nditha kuyang'anitsitsa valavu ya EGR ndi zingwe zonse zolumikizira ndi zolumikizira. Yang'anani pa zingwe zama waya zomwe zimayendetsedwa pafupi ndi zida zotentha komanso m'mbali mwammbali nthawi zambiri zimalumikizidwa ndi zotchinga zotulutsa utsi.

Dziwani: Chotsani owongolera ena onse mdera musanayese kukana / kupitiriza ndi DVOM.

Pogwiritsa ntchito zithunzi zolumikizira ndi zolumikizira zolumikizira zomwe zili mgwero lazidziwitso zamagalimoto anu, yesani gawo lililonse lolumikizira mpweya (ndi DVOM) dera lolozera. Kungakhale kofunikira kuyika pamanja dongosolo la EGR pogwiritsa ntchito sikani, popeza makina ambiri amafunikira liwiro lokhazikitsira musanatsegule lokha. Maulendo omwe samakwaniritsa zomwe wopanga amafunikira adzafunika kuti abwerere komwe adachokera (kawirikawiri cholumikizira PCM) ndikuyesedwanso. Ngati simukupezeka chizindikiro chochokera ku PCM, ganizirani za PCM yolakwika kapena pulogalamu yolakwika ya PCM. M'malo mwake, konzani kapena sinthanitsani masekete otseguka / afupika pakafunika.

Gwiritsani ntchito DVOM kuyesa valavu yeniyeni ya EGR ndi masensa omangidwa ngati ma circuits onse ali mkati mwazomwe opanga amapanga. Gwero lazidziwitso zamagalimoto anu liperekanso chidziwitso kuti muyese gawoli. Ngati utsi wamafuta wotsitsimula wotsitsa komanso masensa onse (ophatikizidwa) sakugwirizana ndi zomwe wopanga akuganiza, akuwakayikira kuti ndizolakwika.

Nambala iyi iyenera kuwonetsedwa pagalimoto zokha zokhala ndi mpweya wamagetsi wotsitsa.

Zokambirana zokhudzana ndi DTC

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

Mukufuna thandizo lina ndi nambala ya P049E?

Ngati mukufunabe thandizo ndi DTC P049E, 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.
