P0016 cholakwika cha mismatch pakati pa zizindikiro za masensa KV ndi RV - chifukwa ndi kuchotsa

29.08.2022 /

Zolakwika p0016 zizindikiro kwa dalaivala kuti pali kusiyana pa malo a shafts. Khodi yotere imatuluka pamene deta yochokera ku crankshaft ndi camshaft sensors (DPKV ndi DPRV) sizikufanana, ndiko kuti, malo aang'ono a camshaft ndi crankshaft wachibale wina ndi mzake wapatuka kuchokera ku chikhalidwe.

Khodi yolakwika P0016: chifukwa chiyani ikuwoneka?

Nthawi ya mavavu - nthawi yotsegula ndi kutseka kwa mavavu olowetsa ndi kutuluka, omwe nthawi zambiri amawonetsedwa mumayendedwe a crankshaft ndipo amadziwika poyerekezera ndi nthawi yoyamba kapena yomaliza ya zikwapu zofananira.

Chiŵerengero cha shaft chimagwiritsidwa ntchito ndi wolamulira kuti adziwe ngati ma cylinders ali okonzeka asanayambe jekeseni wa mafuta kuchokera ku majekeseni ofanana. Deta yochokera ku camshaft sensor imagwiritsidwanso ntchito ndi ECM kudziwa mipata. Ndipo ngati ECU sichilandira chidziwitso chotere, imapanga chizindikiro cha matenda kuti chiwonongeke, ndipo imapanga mafuta pogwiritsa ntchito njira yoyatsira yapawiri-synchronous.

Kulakwitsa kotereku kumakhala kochitika m'magalimoto okhala ndi nthawi yoyendera, koma pamagalimoto okhala ndi lamba wanthawi, nthawi zina amathanso kutuluka. Panthawi imodzimodziyo, khalidwe la galimoto silingasinthe kwambiri; pa makina ena, ngati cholakwika p 016 chikuchitika, galimoto imataya mphamvu ndipo injini yoyaka mkati imakhala ndi mantha. Komanso, cholakwika choterechi chikhoza kuwoneka m'njira zosiyanasiyana (pamawotha, osagwira ntchito, osanyamula), zonse zimatengera zomwe zidachitika.

Zoyenera kuwonetsa kusweka

Khodi yolephera imasainidwa pamene DPRV control pulse sichingadziwike pazigawo zofunikira pazitsulo zonse za 4. Nthawi yomweyo, nyali yoyang'anira pagulu la zida zomwe zikuwonetsa kuwonongeka ("cheke") imayamba kuyaka pambuyo pa kuwongolera kwa 3 ndikulephera, ndikuzimitsa ngati kusweka kotere sikunadziwike panthawi ya 4 motsatizana. Chifukwa chake, ngati pali kuyatsa kwanthawi ndi nthawi kwa chowongolera, izi zitha kukhala chifukwa chakulumikizana kosadalirika, kuwononga zowonongeka ndi / kapena mawaya osweka.

Zifukwa zolakwika

M'nkhaniyi, ziyenera kukumbukiridwa kuti CKP (crankshaft position) crankshaft sensor ndi mtundu wa jenereta yokhazikika ya maginito, yomwe imatchedwanso variable resistance sensor. Mphamvu ya maginito ya sensa iyi imakhudzidwa ndi gudumu lopatsirana lomwe limayikidwa pa shaft yamoto, yomwe ili ndi mipata 7 (kapena mipata), 6 yomwe ili yofanana kuchokera kwa wina ndi mzake ndi madigiri 60, ndipo yachisanu ndi chiwiri ili ndi mtunda wa madigiri 10 okha. Sensa iyi imapanga ma pulse asanu ndi awiri pa kusintha kwa crankshaft, yomaliza yomwe, yokhudzana ndi gawo la 10-degree slot, imatchedwa sync pulse. Kugunda kumeneku kumagwiritsidwa ntchito kulumikiza kutsatizana kwa coil ndi malo a crankshaft. Sensor ya CKP, nayonso, imalumikizidwa ndi sensor yapakati ya injini (PCM) kudzera pagawo lazizindikiro.

Sensor ya camshaft position (CMP) imayendetsedwa ndi sprocket yomwe imayikidwa mu exhaust camshaft sprocket. Sensa iyi imapanga ma pulses 6 ndi kusintha kulikonse kwa camshaft. Zizindikiro za CMP ndi CKP zimakhala ndi pulse-width coded, zomwe zimalola PCM kuyang'anitsitsa ubale wawo nthawi zonse, zomwe zimapangitsa kuti malo enieni a camshaft actuator adziwike ndikuwunika nthawi yake. Sensa ya CMP imalumikizidwa ndi PCM kudzera pa 12 volt circuit.

Kuti mudziwe chifukwa chake zolakwika za P0016 zidawonekera, muyenera kudalira zifukwa zisanu:

  1. Kuyanjana koipa.
  2. Kuwonongeka kwa mafuta kapena njira zotsekera mafuta.
  3. Zomverera CKPS, CMPS (malo masensa kuti / mu r / mu).
  4. Valve ya OCV (valavu yowongolera mafuta).
  5. CVVT (Variable Valve Timing Clutch).

VVT-i ndondomeko

Mu 90% ya milandu, cholakwika cha shaft mismatch chimawoneka ngati pali zovuta ndi VVT-i system, yomwe ndi:

  • Kulephera kwa Clutch.
  • Kuwonongeka kwa valavu yowongolera vvt-i.
  • Kuphika masamba a mafuta.
  • Fyuluta ya valve yotsekeka.
  • Mavuto omwe abwera ndi kuyendetsa nthawi, monga unyolo wotambasulidwa, chopondereza chotha komanso chonyowa.
Kutulutsa lamba/unyolo ndi dzino limodzi lokha pochotsa nthawi zambiri kumatha kubweretsa nambala ya P1.

Njira zochotsera

Nthawi zambiri, dera lalifupi, lotseguka mu gawo la sensor sensor, kapena kulephera kwake (kuvala, kuphika, kuwonongeka kwamakina) kumachitika. Nthawi zina, vuto la ubale wa malo a shafts likhoza kuchitika chifukwa cha kusweka kwa wowongolera liwiro lopanda ntchito kapena rotor ya holo.

Milandu yayikulu yothetsera vutoli ndi kulumikizana kwa masensa ndikuchotsa cholakwika cha P0016 kumachitika mutatha kulowetsa unyolo wotambasulidwa ndi cholumikizira chake.

M'mikhalidwe yapamwamba, njirayi sikhala yochepa, chifukwa tcheni chotambasula chimadya mano a gear!

Pamene eni galimoto kunyalanyaza nthawi yake m'malo mafuta mu injini kuyaka mkati, ndiye, kuwonjezera pa mavuto ena onse, zikhoza kuchitika ndi ntchito VVT clutch, chifukwa kuipitsidwa kwa ngalande mafuta a geometry. shaft control clutch, imathandizira kugwira ntchito kolakwika, ndipo chifukwa chake, cholakwika cholumikizira chimatuluka. Ndipo ngati mbale yamkati imakhala yovala, ndiye kuti clutch ya CVVT imayamba kugwedezeka.

Njira zopezera zochitika za gawo lolakwa ziyenera kuyamba ndikuyang'ana mawaya a PKV ndi PRV masensa, ndiyeno motsatizana, poganizira zomwe zili pamwambazi zomwe zimakhudza kugwirizanitsa kwazitsulo.

Ngati cholakwikacho chidawonekera pambuyo pa njira zoyambira ndi ma shafts, ndiye kuti chinthu chamunthu nthawi zambiri chimakhala ndi gawo pano (chinachake chinakhazikitsidwa cholakwika, chophonya kapena chosapotozedwa).

Kukonza Malangizo

Kuti muzindikire bwino vuto la P0016, makanika nthawi zambiri amachita izi:

  • Kuyang'ana kowonekera kwa kulumikizana kwa injini, ma waya, masensa a OCV, ma camshaft ndi ma crankshaft.
  • Yang'anani mafuta a injini kuti apeze kuchuluka kokwanira, kusakhalapo kwa zonyansa komanso kukhuthala koyenera.
  • Yatsani ndi kuzimitsa OCV kuti muwone ngati sensa ya camshaft ikulembetsa kusintha kwa nthawi ya banki 1 camshaft.
  • Chitani mayeso opanga ma code P0016 kuti mupeze chomwe chimayambitsa code.

Zina mwazokonza zomwe zimachitika kwambiri kuti DTC ithe izi ndi izi:

  • Bwezeraninso ma code amavuto otsatiridwa ndi test drive.
  • Kusintha sensor ya camshaft pa banki 1.
  • Konzani mawaya ndi kulumikizana ndi camshaft ya OCV.
  • Kusintha camshaft ya OCV.
  • Kusintha unyolo wanthawi.

Musanalowe m'malo kapena kukonzanso mulimonse, tikulimbikitsidwa kuti muyese mayeso onse omwe ali pamwambawa kuti ma code asawonekerenso ngakhale mutasintha gawo lomwe limagwira ntchito m'malo mwake.

DTC P0016, ngakhale imasonyezedwa ndi zizindikiro zambiri, siziyenera kunyalanyazidwa. Ngakhale galimotoyo ingakhale yoyenera kuyenda pamsewu, kugwiritsa ntchito galimotoyo kwa nthawi yaitali ndi DTC kungayambitse kuwonongeka kwa injini, kupangitsa kuti zinthu zikhale zovuta kwambiri. Zitha kuchitikanso kuti mavuto amapezeka m'matensioners, ndipo nthawi zina zimatha kuchitika kuti ma valve omwe akugunda ma pistoni amatha kuwononga zina.

Chifukwa cha zovuta za ntchito zowunikira ndi kukonza, ndikofunikira kuyika galimotoyo kwa makanika wabwino.

N'zovuta kulingalira ndalama zomwe zikubwera, chifukwa zambiri zimadalira zotsatira za matenda omwe amachitidwa ndi makaniko. Nthawi zambiri, mtengo wosinthira masensa mumsonkhanowu ndi pafupifupi ma euro 200.
