Mapepala a OBD-II DTC

Dera "A" la turbocharger / supercharger boost regulator, chizindikiro chokwera

Kodi izi zikutanthauzanji?

Izi Diagnostic Trouble Code (DTC) ndi njira yofalitsira, zomwe zikutanthauza kuti imagwira ntchito pamagalimoto okhala ndi OBD-II omwe ali ndi supercharger kapena turbocharger (Toyota, GMC Chevrolet Duramax, Mazda, Chrysler, Jeep, Ford Powerstroke, etc.).) . Ngakhale zambiri, njira zakukonzanso zitha kusiyanasiyana kutengera mtundu / mtundu.

Turbocharger ndi supercharger ndi mapampu a mpweya omwe amakakamiza mpweya kulowa mu injini kuti muwonjezere mphamvu. Ma supercharger amayendetsedwa ndi lamba kuchokera ku crankshaft ya injini, pomwe ma turbocharger amayendetsedwa ndi mpweya wotulutsa injini.

Magalimoto ambiri amakono ogwiritsa ntchito turbocharger amagwiritsa ntchito otchedwa variable geometry turbocharger (VGT). Mtundu wa turbocharger uli ndimasamba osinthika kunja kwa chopangira mphamvu chomwe chitha kutsegulidwa ndikutseka kuti chisinthe kuchuluka kwakulimbikitsira. Izi zimapangitsa turbo kuti iziyendetsedwa mosadalira kuthamanga kwa injini. Nthawi zambiri ma vanes amatseguka pomwe injini ikulemera pang'ono ndipo imatseguka ikamakula. Malo omwe ali nawo amayang'aniridwa ndi module powertrain control module (PCM), nthawi zambiri kudzera pamagetsi oyendetsa magetsi kapena mota. Udindo wa turbocharger umatsimikizika kugwiritsa ntchito sensa yapadera.

Pamagalimoto omwe amagwiritsa ntchito njira yokhazikika yosinthira turbocharger kapena supercharger, zowonjezera zimayendetsedwa kudzera mu zinyalala kapena zinyalala. Valavuyi imatsegulidwa kuti ipereke mphamvu yakulimbikitsira. PCM imayang'anitsitsa dongosolo lino ndi mphamvu yowonjezera mphamvu.

Pa DTC iyi, "A" imawonetsa vuto m'chigawo china osati chizindikiro kapena chinthu china.

Code P0048 idakhazikitsidwa pomwe PCM imapereka mphamvu yolimbikitsira mphamvu yamagetsi, kaya injini ikugwiritsa ntchito VGT turbocharging kapena turbocharger / supercharger yachikhalidwe.

Mtundu umodzi wa turbocharger boost control solenoid valve:

Zokhudzana ndi Turbo / Supercharger Engine DTC Codes:

• P0045 Turbocharger / Supercharger Zowonjezera Kuwongolera «A» Dera / Kutsegula
• P0046 Turbocharger / Supercharger Boost Control "A" Maulendo Ozungulira / Magwiridwe
• P0047 Turbocharger / Supercharger Limbikitsani Kuwongolera «A» Dera Low
• P0049 Turbocharger / Supercharger Turbine Yopitilira
• P004A Turbocharger / Supercharger Boost Control "A" Dera losakhazikika / losakhazikika

Kuuma kwa code ndi zizindikilo

Kuvuta kwa ma code awa ndikwapakati mpaka kukhwima. Nthawi zina, zovuta za turbocharger/supercharger zimatha kuwononga injini kwambiri. Ndikoyenera kukonza code iyi posachedwa.

Zizindikiro za chikhombo cha P0048 zitha kuphatikizira izi:

• Kuchulukitsa kwambiri kumapangitsa kugogoda komanso kuwonongeka kwa injini
• Chongani Engine Kuwala

zifukwa

Zifukwa zomwe zingakhazikitsire nambala iyi:

• Mphamvu yolimbitsa mphamvu / turbocharger position sensor
• Zowonongeka turbocharger / supercharger
• Opunduka ulamuliro solenoid
• Mavuto a zingwe
• PCM yolakwika
• Kutuluka kwa zingalowe ngati valavu imayang'aniridwa ndi zingalowe

Njira zowunikira ndikukonzanso

Yambani poyang'ana poyang'ana turbocharger ndi turbocharger control system. Fufuzani malumikizidwe otayirira, ma waya owonongeka, kutuluka kwa zingalowe, ndi zina zambiri. Kenako onani malipoti aukadaulo (TSB) okhudzana ndi vutoli. Ngati palibe chomwe chikupezeka, muyenera kupitilira pakuwunika pang'onopang'ono.

Otsatirawa ndi njira yodziwika bwino popeza kuyesa kwa nambala iyi kumasiyana ndi galimoto ndi galimoto. Kuti muyesetse bwino dongosololi, muyenera kuyang'ana pa chojambula chojambula cha wopanga.

Tsimikizani momwe makina amagwirira ntchito polamula kuti pulogalamu yoyang'anira isinthidwe ndi chida choonera mbali ziwiri. Kwezani liwiro la injini mpaka pafupifupi 1,200 rpm ndikusintha ndi kuzimitsa ma solenoid. Izi ziyenera kusintha injini ya RPM ndipo chida chowonera PID sensa iyeneranso kusintha. Kuthamanga kukasinthasintha, koma woyang'anira PID / wolamulira sanasinthe, akuganiza kuti pali vuto mu sensa kapena dera lake. Ngati RPM sasintha, ganizirani kuti vutoli lili ndi solenoid, turbocharger / supercharger, kapena wiring.

• Kuyesa dera: fufuzani mphamvu ndi nthaka pa solenoid. Chidziwitso: Mukamayesa mayeserowa, solenoid iyenera kulamulidwa ON ndi chida chowunikira. Ngati kulibe mphamvu kapena kulumikiza pansi, muyenera kupeza chithunzi cholumikizira fakitale kuti mudziwe chomwe chikuyambitsa.
• Chongani turbocharger / supercharger: chotsani mpweya kuti muwone turbocharger / supercharger kuti yawonongeka kapena zinyalala. Ngati kuwonongeka kukupezeka, sinthanitsani chipangizocho.
• Chongani malo / kuthamanga kwa sensa ndi dera: nthawi zambiri mawaya atatu amayenera kulumikizidwa ndi chojambulira: mphamvu, nthaka ndi siginecha. Onetsetsani kuti onse atatu alipo.
• Chongani mphamvu ya mphamvu yoyendetsera: Nthawi zina, mutha kuyang'ana ma solenoid poyang'ana kukana kwake kwamkati ndi ohmmeter. Onani Zambiri Zokonza Makampani kuti mumve zambiri. Muthanso kulumikiza solenoid ku mphamvu ndi nthaka kuti muyese ngati ikugwira ntchito.

Zokambirana zokhudzana ndi DTC

Mukufuna thandizo lina ndi nambala yanu ya p0048?

Ngati mukufunabe thandizo ndi DTC P0048, 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.
