P3449 Cylinder 7 Kukhazikitsa / Kuyika Valavu Yoyendetsa Dera / Kutsegula

Mapepala a OBD-II DTC

Cylinder 7 Deactivation / Intake Valve Control Circuit / Open

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, General Motors, Dodge, Jeep, Chevrolet, Chrysler, Ram, ndi zina zambiri. Ngakhale zili zachilendo, njira zowongolera zenizeni zimatha kusiyanasiyana kutengera mtundu wachitsanzo, kupanga, mtundu, ndi kufalitsa.

OBD-II DTC P3449 ndi ma nambala ofanana P3450, P3451 ndi P3452 amalumikizidwa ndi silinda # 7 yolowera vavu yotseka / yoyang'anira dera.

Cholinga chamagetsi oyimitsira / kutsegulira ma valve oyeserera ndi kusintha magwiridwe anthawi zonse (monga njira ya V7 ya injini ya V4) kuti ichulukitse mafuta pakamagwira ntchito zochepa monga kuyendetsa pamsewu. Ma module a injini (ECM) amawongolera ma 8- kapena 4-cylinder engine modes, kuphatikiza ma valve oyimitsa otsekemera amagetsi anayi a injini. Nambala iyi imanena za silinda nambala 8, ndipo masilindala ena atatu munjira imeneyi amatsimikizidwa ndi kasinthidwe ka injini ndi kuwombera kwamphamvu. Cylinder deactivation solenoid nambala wani imayikidwa pafupi kapena pafupi ndi polowera pafupi ndi silindayi, kutengera galimoto ndi kasinthidwe kake.

ECM ikazindikira mphamvu yachilendo kapena kukana mu cylinder 7 deactivation / control valve control dera, DTC P3449 imakhazikika ndipo kuwala kwa injini kuwunika posachedwa kuwunikira, kuwunikira kwa injini, kapena zonsezi zitha kuwunikira. Nthawi zina, ECM ikhoza kulepheretsa jekeseni wa silinda # 7 mpaka vutolo litakonzedwa ndikukhazikitsa kachidindo, zomwe zimapangitsa kuti injini iwonongeke.

Cylinder kutseka solenoids:

Kodi kuuma kwa DTC kumeneku ndi kotani?

Kukula kwa code iyi kumatha kusiyanasiyana kuchokera pakulimbitsa mpaka pakulimba kutengera zizindikilo zavutoli. Zoyatsira zaposachedwa zimafunikira kuyang'aniridwa mwachangu chifukwa zimatha kuwononga makina amkati amkati.

Kodi zina mwazizindikiro za code ndi ziti?

Zizindikiro za vuto la P3449 zitha kuphatikiza:

• Engine mwina wonongeka
• 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 P3449 zitha kuphatikizira izi:

• Wopanda yamphamvu shutdown solenoid
• Mafuta otsika a injini kapena kuthamanga
• Kupitilira mafuta pang'ono
• Kulumikizana kolakwika kapena kowonongeka
• Zowonongeka, zowonongeka kapena zotayirira
• ECM yolakwika

Kodi ndi njira ziti zina zothetsera P3449?

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

Gawo lachiwiri ndikuwunika momwe mafuta a injini alili ndikuwonetsetsa kuti akusungidwa pamlingo woyenera. Kenaka, pezani zigawo zonse zomwe zimagwirizanitsidwa ndi cylinder 7 inlet shut-off valve control circuit ndikuyang'ana kuwonongeka kwa thupi. Kutengera ndi galimoto yeniyeni, derali likhoza kukhala ndi zigawo zingapo, kuphatikizapo shutdown solenoid, masiwichi, zizindikiro zolakwika, 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 kuphatikiza zolumikizira zonse zamagetsi ndi zolumikizira kuzinthu zonse, kuphatikiza ECM. Yang'anani pepala la deta la galimoto kuti muwone kusintha kwa cylinder 7 shutoff / inlet valve control circuit ndi kutsimikizira chigawo chilichonse chomwe chikuphatikizidwa mu dera, chomwe chingaphatikizepo fuse kapena fusible link.

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?

• Kuchotsa pulogalamu yoyimitsa mphamvu
• Kukonza zolumikizira ndi dzimbiri
• Konzani kapena sinthanitsani zingwe zolakwika
• Mafuta ndi fyuluta zimasintha
• Kuyeretsa malo odutsa mafuta
• Kuwala kapena kusintha ECM

Vuto lalikulu

• Kubwezeretsa pulojekitiyi ndi mafuta osakwanira kapena waya wolakwika kumapangitsa ECM kukhazikitsa nambala iyi.

Tikukhulupirira kuti zambiri zomwe zili m'nkhaniyi zakuthandizani kuloza njira yoyenera yothetsera vuto la kulowetsa ma valve / silinda 7 dera loletsa vuto la DTC. patsogolo.
