Mene ne wannan yake nufi?
Wannan Lambar Matsalar Bincike (DTC) lambar watsawa ce gaba ɗaya, wanda ke nufin ya shafi motocin OBD-II sanye take. Kodayake gabaɗaya a cikin yanayi, takamaiman matakan gyara na iya bambanta dangane da alama / ƙirar.
Lokacin da na ci karo da lambar P212D da aka adana, na gano cewa yana nufin cewa na'urar sarrafa wutar lantarki (PCM) ta gano babban shigarwar wutar lantarki daga ma'aunin firikwensin matsayi (TPS) ko takamaiman firikwensin matsayi na pedal (PPS). "G" yana nufin wani da'ira, firikwensin, ko yanki na wani kewaye.
Koma zuwa tushen amintaccen bayanin abin hawa (duk bayanan DIY zasuyi aiki) don cikakkun bayanan abin hawa da ake tambaya. Ana amfani da wannan lambar ne kawai a cikin motocin da aka sanye da tsarin tuƙi-ta waya (DBW).
PCM ɗin yana sarrafa tsarin DBW ta amfani da matattarar matattara, ɗaya ko fiye na firikwensin matsayin kafa (wani lokacin ana kiranta firikwensin matsayin ƙwallon ƙafa), da firikwensin matsayi mai yawa. Na'urorin firikwensin suna da ƙarfin lantarki (yawanci 5 V) da ƙasa. Yawancin firikwensin TPS / PPS na nau'in potentiometer ne kuma suna kammala madaidaicin da ya dace. Extensionaukar ƙaramar gatari mai ɗorewa akan ƙafar hanzari ko akan maƙerin maƙallan yana kunna lambobin firikwensin. Canjin firikwensin yana canzawa yayin da fil ɗin ke motsawa a cikin PCB mai firikwensin, yana haifar da canje -canje a juriya na kewaye da siginar shigar da siginar zuwa PCM.
Idan ƙarfin shigar da siginar ya wuce iyakar da aka tsara, za a adana lambar P212D na wani lokaci mai tsawo da kuma ƙarƙashin wasu yanayi, kuma Fitilar Nuni ta Malfunction (MIL) na iya haskakawa.
Alamun / tsananin
Lokacin da aka adana wannan lambar, PCM za ta fara shiga yanayin tausasawa. A cikin wannan yanayin, saurin injin zai kasance mai iyakancewa sosai (idan ba a kashe shi ba). Alamomin lambar P212D na iya haɗawa da:
- Maƙura maƙil (a kowane rpm)
- Ƙuntataccen hanzari ko babu hanzari
- Injin yana tsayawa yayin bacci
- Oscillation akan hanzari
- Gudanar da jirgin ruwa ba ya aiki

Mai yiwuwa sanadin wannan lambar injin ya haɗa da:
- Buɗewa ko gajere kewaye a cikin sarkar tsakanin TPS, PPS da PCM
- TPS mara kyau ko PPS
- Gurbatattun masu haɗin lantarki
- M mota mai sarrafa madogara
Hanyoyin bincike da gyara
Kyakkyawan farawa shine koyaushe bincika takaddun sabis na fasaha (TSB) don takamaiman abin hawa. Matsalar ku na iya zama sanannen batun tare da sanannen gyaran masana'anta kuma yana iya adana ku lokaci da kuɗi yayin bincike.
Zan iya samun damar na'urar daukar hoto mai gano cutar, na'urar volt/ohmmeter na dijital (DVOM), da tushen bayanan abin hawa kamar Duk Bayanai (DIY) don tantance lambar P212D.
Zan ɗauki matakin farko na ganewar asali na tare da duban gani na duk wayoyi da masu haɗin haɗin da ke da alaƙa da tsarin. Ina kuma so in bincika jikin magudanar don alamun haɓakar carbon ko lalacewa. Wuce kitse na carbon wanda ke riƙe jikin magudanar buɗe yayin farawa na iya haifar da adana lambar P212D. Decarbonate ma'aunin jiki kamar yadda masana'anta suka ba da shawarar kuma gyara ko maye gurbin wayoyi ko abubuwan da ba su da kyau kamar yadda ake buƙata, sannan a sake duba tsarin DBW.
Daga nan sai in haɗa na'urar daukar hotan takardu zuwa tashar binciken abin hawa sannan in dawo da duk lambobin matsala da aka adana. Na rubuta shi kawai idan kuna buƙatar tsarin da aka adana lambobin. Ina kuma son adana duk wani bayanan da ke da alaƙa da firam. Waɗannan bayanan kula na iya taimakawa idan P212D zai yi aiki na ɗan lokaci. Yanzu na share lambobin kuma na gwada motar. Idan an sake saita lambar, Ina ci gaba da gano cutar
Ana iya gano ƙarfin wutar lantarki da rashin daidaituwa tsakanin TPS, PPS da PCM ta amfani da rafin bayanan na'urar daukar hotan takardu. Kunkuntar da bayanan ku don nuna bayanai masu dacewa kawai don amsawa da sauri. Idan ba a sami spikes da / ko rashin daidaituwa ba, yi amfani da DVOM don samun bayanai na ainihi daga kowane firikwensin daban. Don samun bayanai na ainihi ta amfani da DVOM, haɗa gwajin yana kaiwa ga siginar da ta dace da da'irar ƙasa da lura da nuni na DVOM yayin da DBW ke gudana. Lura ƙarfin lantarki yana ƙaruwa yayin sannu a hankali yana motsa bawul ɗin maƙera daga rufe zuwa cikakken buɗewa. Yawan wutar lantarki yawanci yana daga 5V rufe maƙura zuwa 4.5V m bude maƙura. Idan an sami surges ko wasu munanan halaye, yi zargin cewa firikwensin da ake gwadawa yana da lahani. Oscilloscope shima babban kayan aiki ne don tabbatar da aikin firikwensin.
Ƙarin bayanin kula:
- Wasu masana'antun suna buƙatar jujjuyawar motar, matattarar mai kunnawa, da duk firikwensin matsayin maƙura don maye gurbinsu tare.
Tattaunawar DTC mai dangantaka
- A halin yanzu babu batutuwa masu alaƙa a cikin dandalin mu. Sanya sabon taken akan dandalin yanzu.
Kuna buƙatar ƙarin taimako tare da lambar p212D?
Idan har yanzu kuna buƙatar taimako game da DTC P212D, aika tambaya a cikin sharhin da ke ƙasa wannan labarin.
NOTE. An ba da wannan bayanin don dalilai na bayanai kawai. Ba a yi nufin amfani da shi azaman shawarar gyara ba kuma ba mu da alhakin duk wani mataki da za ku ɗauka a kan kowane abin hawa. Duk bayanan da ke wannan shafin ana kiyaye su ta haƙƙin mallaka.
