P212D Fulumizitsa Udindo SENSOR / Sinthani G Lowetsani Circ High

Mapepala a OBD-II DTC

Mkulu wa chizindikiro cholowera mu unyolo wa sensa ya malo a butterfly valve / switch "G"

Kodi izi zikutanthauzanji?

Izi Diagnostic Trouble Code (DTC) ndi njira yolozera, zomwe zikutanthauza kuti imagwira ntchito pamagalimoto okhala ndi OBD-II. Ngakhale zambiri, njira zina zakukonzanso zimatha kusiyanasiyana kutengera mtundu / mtundu.

Nditapeza kachidindo kosungidwa P212D, ndinapeza kuti zikutanthauza kuti powertrain control module (PCM) yapeza kulowetsa kwamagetsi kuchokera ku Throttle Position Sensor (TPS) dera kapena Pedal Position Sensor (PPS) dera. "G" amatanthauza dera linalake, sensa, kapena dera linalake lozungulira.

Tchulani gwero lodalirika lazidziwitso zamagalimoto (zambiri za DIY zigwira ntchito) kuti mumve zambiri za galimoto yomwe ikufunsidwayo. Code iyi imagwiritsidwa ntchito pamagalimoto okhala ndi ma drive-by-waya (DBW).

PCM imayang'anira dongosolo la DBW pogwiritsa ntchito fulumizitsa actuator mota, imodzi kapena zingapo zamagetsi zamagetsi (nthawi zina amatchedwa accelerator pedal position sensors), ndi masensa angapo opumira. Masensa amakhala ndi voliyumu yamagetsi (makamaka 5 V) ndi nthaka. Masensa ambiri a TPS / PPS ndi amtundu wa potentiometer ndipo amaliza dera loyenera. Kutambasula kwazitsulo kozungulira pazitsulo zamagetsi kapena pa shaft ya fulumizitsa kumathandizira olumikizana ndi sensa. Kukaniza kwamasensa kumasintha pomwe zikhomo zimadutsa pa sensor ya PCB, zomwe zimayambitsa kusintha kwa mayendedwe amagetsi ndikuwonetsera magetsi ku PCM.

Ngati mphamvu yamagetsi yolowera ipitilira malire omwe adakonzedwa, kwa nthawi yayitali komanso munthawi zina, code P212D idzasungidwa ndipo Nyali Yowonongeka Yowonongeka (MIL) ikhoza kuunikira.

Zizindikiro / kuuma kwake

Code iyi ikasungidwa, PCM nthawi zambiri imalowa m'malo opunduka. Munjira iyi, mathamangitsidwe a injini adzakhala ochepa kwambiri (kupatula ngati atalephereka). Zizindikiro za nambala ya P212D zingaphatikizepo:

• Kukhazikika (nthawi zonse)
• Kuthamangira kocheperako kapena kuchepa kwachangu
• Makola a injini mukamachita ulesi
• Kuchotsa mwachangu
• Kuwongolera ngalawa sikugwira ntchito

zifukwa

Zomwe zingayambitse kachidindo kameneka ndi monga:

• Dera lotseguka kapena lalifupi mu unyolo pakati pa TPS, PPS ndi PCM
• Zolakwika TPS kapena PPS
• Zowonongeka zamagetsi
• Opunduka mphamvu ya kutali pagalimoto galimoto

Njira zowunikira ndikukonzanso

Malo oyambira nthawi zonse amayang'ana ma bulletins aukadaulo (TSB) pagalimoto yanu. Vuto lanu limatha kukhala vuto lodziwika bwino lokonzedwa ndi wopanga ndipo limatha kukupulumutsirani nthawi ndi ndalama mukamayesa kusaka.

Nditha kukhala ndi makina ojambulira, digito volt / ohmmeter (DVOM), komanso gwero lazidziwitso zamagalimoto monga All Data (DIY) kuti ndizindikire khodi ya P212D.

Ndikadatenga gawo loyamba lachidziwitso changa poyang'ana mawaya onse ndi zolumikizira zogwirizana ndi dongosolo. Ndimakondanso kuyang'ana thupi la throttle ngati pali zizindikiro za carbon build up kapena kuwonongeka. Kuchuluka kwa mpweya wa carbon komwe kumapangitsa kuti thupi likhale lotseguka poyambitsa kungapangitse kuti code ya P212D isungidwe. Tsukani ma dipoziti aliwonse a kaboni kuchokera m'thupi la throttle molingana ndi malingaliro a wopanga ndikukonza kapena kusintha mawaya olakwika kapena zigawo zina ngati pakufunika, kenako yesaninso dongosolo la DBW.

Kenako ndimalumikiza chojambulira ku doko loyang'anira galimoto ndikubweza ma DTC onse osungidwa. Ndimalemba ngati mungafune dongosolo lomwe ma code adasungidwa. Ndimakondanso kusunga deta iliyonse yokhudzana ndi chimango. Zolemba izi zitha kukhala zothandiza ngati P212D sichita bwino. Tsopano ndikuchotsa ma code ndikuyesa kuyendetsa galimoto. Ngati kachidindo kachotsedwa, ndikupitiriza kufufuza

Kuwonjezeka kwamagetsi ndi zolakwika pakati pa TPS, PPS ndi PCM zitha kupezeka pogwiritsa ntchito pulogalamu yolumikizira. Chepetsani kusuntha kwanu kuti muwonetse zidziwitso zofunikira zokha kuti muyankhe mwachangu. Ngati palibe ma spikes ndi / kapena zosagwirizana zomwe zikupezeka, gwiritsani ntchito DVOM kuti mupeze zenizeni zenizeni kuchokera pa sensa iliyonse payokha. Kuti mupeze zenizeni zenizeni pogwiritsa ntchito DVOM, polumikizani mayesowo amatsogolera kuzizindikiro zoyenerera ndi mabwalo apansi ndikuwona chiwonetsero cha DVOM pomwe DBW ikuyenda. Onani kukwera kwamagetsi mukamayendetsa pang'onopang'ono valavu yampweya kutseka mpaka kutseguka kwathunthu. Mpweyawo umakhala pakati pa 5V potseka mpaka 4.5V yotseguka. Ngati ma surges kapena zovuta zina zapezeka, ganizirani kuti sensa yomwe ikuyesedwa ndiyolakwika. Oscilloscope ndichinthu chothandiza kwambiri kutsimikizira magwiridwe antchito.

Zowonjezera zowonjezera:

• Opanga ena amafunikira thupi lopumira, makina opumira, ndi masensa onse opumira kuti asinthidwe limodzi.

Zokambirana zokhudzana ndi DTC

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

Mukufuna thandizo lina ndi code p212D?

Ngati mukufunabe thandizo lokhudza DTC P212D, 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.
