P052A Cold start, camshaft position nthawi - mopitirira muyeso, banki 1

Mapepala a OBD-II DTC

Kuzizira kozizira, camshaft nthawi, kupita patsogolo kwambiri, banki 1

Kodi izi zikutanthauzanji?

Imeneyi ndi nambala yovuta yoyeza matenda (DTC) ndipo imagwiritsidwa ntchito kwambiri pamagalimoto a OBD-II. Zogulitsa zamagalimoto zimatha kuphatikiza, koma sizingokhala, VW, Audi, Ford, Nissan, Hyundai, BMW, Mini, Mercedes-Benz, Jeep, ndi zina zambiri.

ECM (Engine Control Module) ndi kompyuta yamphamvu kwambiri yomwe imayang'anira ndikuyang'anira makina oyatsira injini yagalimoto, malo amakanika azinthu zozungulira, jakisoni wamafuta, makina otulutsa, utsi, kutumiza, ndi makina ena ambiri.

Dongosolo lina lomwe ECM liyenera kuyang'anira ndikusintha moyenera ndi nthawi ya valve variable (VVT). Kwenikweni, machitidwewa amalola ECM kuwongolera nthawi yamakina pakati pa camshaft ndi crankshaft. Izi zimawonjezera mphamvu yonse ya injini. Osatchulanso phindu la mafuta. Zowonadi, nthawi yoyenera ya injini yanu iyenera kusinthidwa kuti ikhale yosinthika. Pachifukwa ichi, adapanga dongosolo la VVT.

P052A (chiyambi chozizira, nthawi yowonjezera ya camshaft 1) ndi code yomwe imachenjeza wogwiritsa ntchito kuti ECM yakhala ikuyang'anira "mopitirira malire" - malo owonjezera a VVT kuti azindikire nthawi ya banki 1. Kawirikawiri chifukwa cha kuyamba kozizira . Kudziyesa kwa VVT uku kumalephera chifukwa kuchuluka kwa camshaft kupitilira kapena chifukwa kumakhalabe pamalo otalikirapo. Bank 1 ndi mbali ya injini yomwe ili ndi silinda #1.

Zindikirani. Camshaft "A" ndiyomwe imalowetsa, kumanzere kapena kutsogolo kwa camshaft. Kumanzere/Kumanja ndi Kutsogolo/Kumbuyo kumatanthauzidwa ngati kuti mwakhala pampando wa dalaivala.

Kodi kuuma kwa DTC kumeneku ndi kotani?

Code P052A ndi vuto lomwe liyenera kutumizidwa kwa makaniko nthawi yomweyo chifukwa ndizovuta kwambiri, osasiya vuto lalikulu. Vuto lamtunduwu limakhudza kwambiri ECM, kotero katswiri ayenera kuyang'ana galimoto yanu ngati izi kapena DTC yokhudzana nayo ikuwonekera. Nthawi zambiri ECM sizindikira kuyankha komwe kumafunikira pamalamulo angapo apakompyuta a VVT ​​ndipo code idakhazikitsidwa.

Popeza vutoli limayambitsidwa ndimasinthidwe amagetsi a nthawi yamagetsi, omwe ndimayendedwe amagetsi, magwiridwe ake azikhala ochepa m'malo opindika, mukamayendetsa m'misewu yopanda pake, kapena pakuyenda mwamphamvu. Osanenapo kusintha kosalekeza kwa dongosololi kuti athetse mavuto, kumabweretsa mafuta ochulukirapo komanso kuwoneka kwamavuto akamagwa mafuta, omwe amakhudza magwiridwe antchito a VVT.

Kodi zina mwazizindikiro za code ndi ziti?

Zizindikiro za kachidindo ka P052A zitha kuphatikizira izi:

• Kugwiritsa ntchito injini molakwika
• Kuchepetsa mafuta
• Zotheka kusokonekera poyambira
• Mavuto oyambira ozizira

Kodi zina mwazomwe zimayambitsa codezi ndi ziti?

Zoyambitsa za P052A DTC zitha kuphatikizira izi:

• Crankshaft malo kachipangizo zosalongosoka
• Camshaft udindo kachipangizo kuonongeka
• Valavu ya solenoid yolamulira magawo amagetsi olowera ndi olakwika
• Khomo lolowera mkati lopangira valavu ndi lolakwika.
• Zinyalala zasonkhanitsidwa mdera lolandila camshaft.
• Chingwe cha nthawi chayikidwa molakwika
• Zinthu zakunja zimaipitsa poyambira mafuta pochepetsa magawo amagetsi.

Kodi ndi njira ziti zodziwira ndikusokoneza P052A?

Gawo loyamba pamavuto amtundu uliwonse ndikuwunikanso za Technical Service Bulletins (TSB) pamavuto odziwika ndi galimoto inayake.

Njira zodziwitsira zapamwamba zimangokhala zododometsa kwambiri zamagalimoto ndipo zimatha kufunikira zida zoyenerera komanso chidziwitso kuti zichitike molondola. Timalongosola njira zomwe zili pansipa, koma tchulani buku lanu lokonzekera galimoto / mapangidwe / mtundu / kapangidwe kake ka mayendedwe amtundu wa galimoto yanu.

Onetsetsani kuti mwayang'ana zilembo zamautumiki zomwe zitha kupereka mayankho pamavuto aliwonse, chifukwa magalimoto ambiri ali ndi mapulogalamu osinthidwa mumayendedwe awo oyendetsa injini. Ngati pakufunika kusintha, ndibwino kugwiritsa ntchito fakitale yatsopano ECU ndikukonzekera pulogalamu yatsopano. Gawo ili lidzafunika kuti mupite kumalo ovomerezeka ovomerezeka pagalimoto yanu.

ZINDIKIRANI. Kumbukirani kuti ECM ikhoza kusinthidwa mosavuta ngati injini ya injini ilidi yolakwika, zomwe zingakhale chifukwa cha gawo lomwe likusowa pakuwunika koyambirira. Ichi ndichifukwa chake akatswiri amakono amatsatira mtundu wina wa tchati poyang'ana DTC kuti itetezedwe molakwika. Nthawi zonse ndibwino kuti mufunsane zambiri zautumiki wanu poyamba.

Atanena izi, ndibwino kuti muwone ngati camshaft.cuum idaduka nthawi yomweyo, chifukwa zimatha kubweretsa mavuto ena mtsogolo ngati angadzasiyidwe osayang'aniridwa. Onaninso buku lanu lautumiki pazinthu zina zakuwunikira ndi malo omwe amapezeka.

Kutengera mtundu wa camshaft position sensor yomwe muli nayo (monga Hall athari, sensor yotsutsana, etc.), matendawa amasiyana kutengera wopanga ndi mtundu wake. Poterepa, sensa iyenera kupatsidwa mphamvu kuti iwunikire pomwe pali ma shafts. Ngati cholakwika chikupezeka, sinthani kachipangizo, konzani ma code ndikuyesa kuyendetsa galimotoyo.

Popeza kuti pali "kuyamba kozizira" pamafotokozedwe amtunduwu, muyenera kuti muyang'ane injector yanu yoyambira yozizira. Itha kukhalanso mutu wokwera ndipo imapezeka pamlingo winawake. Zingwe za nozzle zimatha kuwuma ndi kuphwanya chifukwa cha zinthu zomwe zimayambitsa kulumikizana kwapakatikati. Ndipo mwina vuto loyambira kuzizira. Samalani kwambiri mukadula cholumikizira chilichonse cha jakisoni mukazindikira. Monga tanenera, ndi osalimba.

Nkhaniyi ndi yongofuna kudziwa zambiri komanso zidziwitso zaumisili ndi zolembera zamagalimoto anu nthawi zonse ziyenera kukhala patsogolo.

Zokambirana zokhudzana ndi DTC

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

Mukufuna thandizo lina ndi nambala ya P052A?

Ngati mukufunabe thandizo lokhudza DTC P052A, 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.
