P2438 Secondary mpweya jekeseni dongosolo mpweya otaya / kuthamanga sensa dera, banki 2

Mapepala a OBD-II DTC

Secondary Air Misa / Anzanu SENSOR Dera Bank 2

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 sikuchepera ku, Buick, Chevrolet, Cadillac, Lexus, Toyota, BMW, Subaru, ndi zina zambiri. Ngakhale zili choncho, njira zowongolera zenizeni zimatha kusiyanasiyana kutengera mtundu wachitsanzo, kapangidwe, kapangidwe ndi kapangidwe kake. ...

OBD-II DTC P2438 ndi manambala ofananira P2435, P2436, P2437 ndi P2439 amagwirizana ndi njira yachiwiri ya jakisoni wa mpweya / sensor sensor circuit bank 2. Block 2 ndi mbali ya injini yomwe ilibe silinda # 1.

Dulani 2 yoyendera mpweya / kuthamanga kwa sensa yoyeserera ya jekeseni ya mpweya yachiwiri idapangidwa kuti ichepetse kuchuluka kwama utsi wama hydrocarbon omwe amatulutsidwa injini ikayamba nyengo yozizira. Power Control Module (PCM) imayambitsa mpope wa mpweya kuti upereke mpweya wabwino wopanikizika kuti uthandizire kugwira ntchito, kuchepetsa utsi woyipa. Izi zimathandizanso injini kuti izitha kutentha mwachangu. Makina othamangitsira mpweya amagwiritsidwa ntchito poyang'anira kuthamanga kwa mpweya wothamanga wa mpweya kuti utsegule ndi kutseka valavu pamavuto ndi zovuta monga amalimbikitsira opanga.

PCM ikazindikira kuti voliyumu kapena kulimbikira kumakhala kwakukulu kwambiri kuposa miyezo yoyenera kuyembekezera, njira yachiwiri yopangira mpweya, banki 2, kuthamanga kwa mpweya / kuthamanga kwa sensor kumakhazikitsa nambala P2438 ndipo kuwala kwa injini kumatha kuwunikira.

Zida zowonjezera mpweya:

Kodi kuuma kwa DTC kumeneku ndi kotani?

Kukula kwa code iyi kumatha kusiyanasiyana kuchokera pakulimbitsa mpaka pakulimba kutengera zizindikilo zavutoli. Zina mwazizindikiro za DTC iyi zitha kupangitsa kuyendetsa kukhala kowopsa kwambiri.

Kodi zina mwazizindikiro za code ndi ziti?

Zizindikiro za vuto la P2438 zitha kuphatikiza:

• Injini ikhoza kukhazikika pa liwiro laulesi
• Injini siyamba
• Sekondale mpweya jekeseni dongosolo limapanga phokoso
• Kugwiritsa ntchito injini molakwika
• Chowunikira cha injini chikuyatsa

Kodi zina mwazomwe zimayambitsa codezi ndi ziti?

Zifukwa za code iyi P2438 zitha kuphatikizira izi:

• Sekondale mpweya jekeseni mpope zosalongosoka
• Chongani valavu zosalongosoka.
• Cholakwika mpweya ulamuliro solenoid valavu
• Mpweya wothamanga wa mpweya wosalongosoka
• Kulumikizana kolakwika kapena kowonongeka
• Zowonongeka, zowonongeka kapena zotayirira
• PCM yolakwika

Kodi ndi njira ziti zina zothetsera P2438?

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.

Kutengera ndi galimotoyi, magawowa atha kuphatikizira zinthu zingapo, kuphatikiza pampu yachiwiri yopopera mpweya, valavu yowunika, makina othamangitsira, vavu wowongolera mpweya, ndi PCM. Onaninso zowunikira kuti muwone zolumikizira zomwe zikugwirizana ndi zolakwika monga kukwapula, abrasions, mawaya opanda kanthu, kapena mawanga owotcha. Chotsatira, muyenera kuyang'anitsitsa zolumikizira ndi kulumikizana kuti zitheke, kuwonongeka ndi kuwonongeka kwa omwe alumikizana nawo. Njirayi iyenera kuphatikiza zolumikizira zamagetsi zonse ndikulumikiza kuzinthu zonse, kuphatikiza PCM. Funsani deta yanu yapaderadera kuti mutsimikizire momwe dera likuyendera ndikusinthira gawo lililonse lomwe lingaphatikizepo fuse kapena fuse. Valavu ya cheke iyenera kufufuzidwa kuti iwonetsetse kuti kutuluka kwa mpweya kuli mbali imodzi kokha. Kukhazikika kwa madzi oundana mu mpope wachiwiri wa jekeseni wa mpweya nthawi yozizira kwambiri kumawonetsa kusayenda bwino kwa valavu yoyendera njira imodzi yolola condensate kuchokera pagasi lotulutsa kuti alowe pampopu.

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 mpope wachiwiri wa jekeseni wa mpweya
• Kuchotsa valavu yoyang'ana njira yolakwika imodzi
• Kusintha kachipangizo kamene kamatulutsa mpweya
• Kuchotsa valavu yowongolera mpweya
• Kukonza zolumikizira ndi dzimbiri
• Konzani kapena sinthanitsani zingwe zolakwika
• Kuwala kapena kusintha PCM

Vuto lalikulu

• Kusintha mpope wachiwiri wa jekeseni wa mpweya pomwe njira yoyipa yoyendera imodzi kapena waya yolakwika imayambitsa PCM iyi.

Tikukhulupirira kuti zomwe zalembedwa m'mbuyomu zakuthandizani kuloza njira yoyenera kuthana ndi vuto la Secondary Air Injection Air Flow / Pressure Sensor Circuit DTC, Bank. galimoto nthawi zonse ziyenera kukhala patsogolo.

Zokambirana zokhudzana ndi DTC

• Thandizani P2438 pa 2007 Tundra yangaNdikuyesera kuti ndipeze mzere wapamwamba 2 wachiwiri woyendetsa jekeseni wa mpweya / kuthamanga kwa sensa. Kodi pali amene angandiwongolere njira yoyenera? Zikomo Gebby43 ... 

Mukufuna thandizo lina ndi code P2438?

Ngati mukufunabe thandizo ndi DTC P2438, 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.
