P2249 O2 Sensor Reference Voltage Bank 2 Sensor 1 Yotsika

Mapepala a OBD-II DTC

O2 SENSOR Reference Bank 2 SENSOR 1 Yotsika

Kodi P2249 amatanthauza chiyani?

Code Yovutikira Ndi Kuzindikira (DTC) ndi nambala yofalitsira ndipo imagwira ntchito pamagalimoto ambiri a OBD-II (1996 ndi atsopano). Izi zitha kuphatikizira, koma sikuchepera, magalimoto ochokera ku Honda, Ford, Mazda, VW, Mercedes-Benz, Audi, Hyundai, Acura, BMW, ndi zina zambiri. za kapangidwe. zopangidwa, mitundu ndi zotumiza. kasinthidwe.

Khodi yosungidwa P2249 imatanthauza kuti powertrain control module (PCM) yapeza voliyumu yotsika ya sensa ya O2 kumtunda kwa injini block 1. SENSOR 2 imatanthawuza kumtunda kwakumtunda ndikuletsa XNUMX kumatanthauza injini yomwe ilibe cholembera nambala wani.

Kuchuluka kwa mafuta pamlengalenga pamzera uliwonse wama injini kumayang'aniridwa ndi PCM pogwiritsa ntchito deta kuchokera pama sensa otentha a oxygen. Chojambulira chilichonse cha oxygen chimamangidwa pogwiritsa ntchito zirconia sensing element yomwe ili mkatikati mwa nyumba yazitsulo. Maelekitirodi ang'onoang'ono (nthawi zambiri amakhala platinamu) amalumikiza chinthu chodziwikiratu ku mawaya omwe ali mu cholumikizira cha oksijeni cholumikizira, ndipo cholumikizacho chimalumikizidwa ndi netiweki yolamulira (CAN) yomwe imalumikiza zingwe za sensa ya oxygen ku cholumikizira cha PCM.

Chojambulira chilichonse cha oksijeni chimasokonekera (kapena kupindika) mu chitoliro cha utsi. Ili bwino kotero kuti chinthu chofunafuna chili pafupi kwambiri ndi chitoliro. Pamene mpweya wotulutsa zinyalala umachoka m'chipinda choyaka moto (kudzera munthawi zambiri za utsi) ndikudutsa mu utsi (kuphatikiza otembenuza othandizira), amadutsa pama sensa a oxygen. Mpweya wotulutsa utsi umalowa mu kachipangizo ka oxygen kudzera muzitsulo zopangidwa mwapadera m'nyumba zazitsulo ndikuzungulira mozungulira. Mpweya wozungulira womwe umazungulira umakokedwa ndi zingwe zazitali zanyumba ya sensa, momwe amadzaza chipinda chaching'ono pakati. Kenako mpweya (m'chipinda chaching'ono) umatentha. Izi zimapangitsa ma ayoni a oxygen kuti apange mphamvu, yomwe PCM imazindikira ngati magetsi.

Kusiyanitsa pakati pa kuchuluka kwa ma ayoni a oxygen mumlengalenga wozungulira (wolowetsedwa mu sensa ya O2) ndi kuchuluka kwa mamolekyulu a oksijeni mu utsi kumapangitsa kuti ma ayoni a oxygen mkati mwa sensa ya O2 abwere mofulumira komanso mosadukiza kuchokera pa pulatinamu imodzi kupita kwina. ... Mitundu ya okosijeni ikamayenda pakati pa magawo a platinamu, mphamvu yotulutsa mpweya wa oxygen imasintha. PCM imawona kusintha kumeneku pamphamvu yamagetsi yotulutsa mpweya monga kusintha kwa mpweya wa mpweya mumafuta otulutsa mpweya. Zotulutsa zamagetsi kuchokera ku zotengera za oxygen ndizotsika pomwe mpweya wambiri umakhalapo mu utsi (dziko lowonda) komanso kupitilira apo mpweya wocheperako umakhalapo mu utsi (chuma).

PCM ikazindikira mtengo wamagetsi wotsika pamagetsi amagetsi a oxygen, nambala ya P2249 idzasungidwa ndipo nyali yowunikira (MIL) itha kuwunikira. Magalimoto ambiri amafunikira mayendedwe angapo oyatsa (akadzalephera) kuti ayatse nyali yochenjeza.

Chitsanzo mpweya kachipangizo O2:

Kodi kuuma kwa DTC kumeneku ndi kotani?

Kusakwanira kwamagetsi pamagetsi oyang'ana pa sensa ya O2 kumatha kubweretsa kuchepa kwachuma kwamafuta ndikuchepetsa magwiridwe antchito a injini. P2249 iyenera kugawidwa mwanjira yayikulu ndipo iyenera kukonzedwa posachedwa.

Kodi zina mwazizindikiro za code ndi ziti?

Zizindikiro za vuto la P2249 zitha kuphatikiza:

Kuchepetsa mafuta
Mphamvu yamagetsi yochepetsedwa
Ma Code Okhutiritsa Osungidwa kapena Ma Code Otsamira / Olemera Otulutsa
Nyali ya injini yothandizira idzawala posachedwa

Kodi zina mwazomwe zimayambitsa codezi ndi ziti?

Zifukwa za code iyi zitha kuphatikizira izi:

Lumikizanani nafe
Zowonongeka zamagetsi / s
Chowotcha chopindika, chosweka, chosweka, kapena chosadulidwa ndi / kapena zolumikizira

Kodi ndi njira ziti zina zothetsera P2249?

Mufunika makina osakira matenda, digito volt / ohmmeter (DVOM), ndi gwero lodalirika lazidziwitso zamagalimoto kuti mupeze nambala ya P2249 molondola.

Mutha kusunga nthawi posaka Technical Service Bulletins (TSBs) yomwe imasunganso nambala yosungidwa, galimoto (chaka, kupanga, mtundu, ndi injini) ndi zizindikilo zomwe zapezeka. Izi zitha kupezeka pagalimoto yanu. Ngati mupeza TSB yoyenera, itha kukonza vuto lanu mwachangu.

Mutatha kulumikiza sikaniyo pagalimoto yodziwitsa magalimoto ndikupeza ma nambala onse osungidwa ndi zomwe zimayimitsidwa pazenera, lembani zidziwitsozo (ngati nambala yake izikhala yapakatikati). Pambuyo pake, chotsani ma code ndikuyesa kuyendetsa galimoto mpaka chimodzi mwazinthu ziwiri zichitike; codeyo ibwezeretsedwa kapena PCM imalowa munjira yokonzeka.

Code ikhoza kukhala yovuta kwambiri kudziwa ngati PCM ilowa m'malo okonzeka pakadali pano chifukwa nambala yake ndiyapakatikati. Chikhalidwe chomwe chinayambitsa kulimbikira kwa P2249 kungafune kukulirakulira asanadziwe molondola. Ngati codeyo yabwezeretsedwa, pitilizani kudziwa.

Mutha kuwona zolumikizira, zolumikizira zolumikizira, malo ophatikizika, zithunzi zolumikizira, ndi zithunzi zazithunzi (zogwirizana ndi nambala ndi galimoto yomwe ikufunsidwayo) pogwiritsa ntchito gwero lazidziwitso zamagalimoto anu.

Yang'anirani zowunikira zolumikizira ndi zolumikizira. Konzani kapena sinthani mawaya odulidwa, owotcha, kapena owonongeka.

Gwiritsani ntchito DVOM kuti muwone mphamvu ya sensa ya O2 pini yoyenera yolumikizira (pafupi ndi sensa). Ngati mulibe magetsi, yang'anani mafayilowo. Sinthanitsani mafyuzi owombedwa kapena olakwika ngati kuli kofunikira.

Ngati magetsi amapezeka, yang'anani dera loyenera pa cholumikizira cha PCM. Ngati palibe magetsi, sakayikira dera lotseguka pakati pa sensa yomwe ikufunsidwa ndi PCM. Ngati magetsi amapezeka pamenepo, ganizirani za PCM yolakwika kapena pulogalamu yolakwika ya PCM.

Kuti muwone masensa a O2: Yambitsani injini ndikulola kuti izitha kutentha. Lolani injini iwonongeke (mosalowerera ndale kapena poyimika). Ndi sikani yolumikizidwa ndi doko lodziwira galimoto, onaninso kulowetsa kwa kachipangizo ka oxygen mumtsinje wa data. Chepetsani kutsika kwanu kuti muphatikize zokhazo zofunikira kuti muyankhe mwachangu.

Ngati masensa a oxygen akugwira ntchito bwino, ma voliyumu opyola masensa a oksijeni kumtunda kwa chosinthira chazizindikiro azingoyenda mosalekeza kuchokera pa 1 mpaka 900 millivolts pomwe PCM ilowa mumalowedwe otsekedwa. Masensa otumizira amphaka azizunguliranso pakati pa 1 ndi 900 millivolts, koma adzakhazikitsidwa nthawi inayake ndikukhala olimba (poyerekeza ndi masensa amkati amphaka). Masensa a oxygen omwe sakugwira ntchito moyenera ayenera kuonedwa ngati olakwika ngati injini ikugwira bwino ntchito.

Fuse ya O2 yotulutsa sikuti imayambitsa nambala yosungidwa ya P2249, koma kuyankha kanthawi kochepa mu dera.

Zokambirana zokhudzana ndi DTC

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

Mukufuna thandizo lina ndi code P2249?

Ngati mukufunabe thandizo ndi DTC P2249, 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.
