Mene ne wannan yake nufi?

Wannan sigar lambar rikitarwa ce mai rikitarwa (DTC) kuma galibi ana amfani da ita ga motocin OBD-II. Wannan na iya haɗawa, amma ba'a iyakance shi ba, motoci daga Toyota, Subaru, Mazda, Ford, Chrysler, Dodge, Hyundai, Jeep, Kia, Volvo, da dai sauransu Kodayake gabaɗaya, matakan gyara daidai na iya bambanta da shekara, yin, samfuri da watsawa. . sanyi.

Lambar da aka adana P2109 tana nufin tsarin sarrafa wutar lantarki (PCM) ya gano rashin aiki a cikin firikwensin matsayin "A" (TPS) ko takamaiman firikwensin matsayi (PPS).

Sunan "A" yana nufin takamaiman firikwensin. Tuntuɓi tushen bayanan abin hawa abin dogaro don cikakkun bayanai na musamman ga abin hawa da ake tambaya. Ana amfani da wannan lambar ne kawai a cikin motocin da ke sanye da tsarin tuƙi-ta-waya (DBW) kuma yana nufin mafi ƙarancin tsayawa ko aikin maƙura.

PCM ɗin yana sarrafa tsarin DBW ta amfani da matattarar matattarar matattarar matattarar matattakala, (wani lokacin ana kiranta firikwensin matsayin ƙwallon ƙafa), da firikwensin matsayi mai yawa. Ana ba da na'urori masu auna firikwensin tare da nuni na 5V, ƙasa da aƙalla waya sigina ɗaya.

Gabaɗaya magana, firikwensin TPS / PPS na nau'in potentiometer ne. Haɗin injin na pedal mai haɓakawa ko ƙwanƙwasawa 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 PCM ta gano tasha / kusa matsin lamba matsayin firikwensin ƙaramin siginar ƙarfin lantarki (daga firikwensin da aka yiwa lakabi da A) wanda bai yi daidai da tsarin da aka tsara ba, za a adana lambar P2109 kuma fitilar mai nuna rashin aiki (MIL) na iya haskakawa. Lokacin da aka adana wannan lambar, PCM galibi yana shiga gurgu. A cikin wannan yanayin, haɓaka injin na iya iyakance sosai (sai dai idan an naƙasa gaba ɗaya).

Menene tsananin wannan DTC?

P2109 yakamata a ɗauka da mahimmanci saboda yana iya sa ba zai yiwu a tuƙi ba.

Menene wasu alamomin lambar?

Alamomin lambar matsala P2109 na iya haɗawa da:

• Rashin mayar da martani
• Ƙuntataccen hanzari ko babu hanzari
• Injin yana tsayawa yayin bacci
• Oscillation akan hanzari
• Gudanar da jirgin ruwa ba ya aiki

Mene ne wasu abubuwan da ke haifar da lambar?

Dalilan wannan lambar firikwensin P2109 / pedal matsayi na iya haɗawa da:

• TPS mara kyau ko PPS
• Buɗewa ko gajere kewaye a cikin sarkar tsakanin TPS, PPS da PCM
• Gurbatattun masu haɗin lantarki
• Motocin DBW mara lahani.

Menene wasu matakai don warware matsalar P2109?

Duba tushen bayanan abin hawa don bayanan sabis na fasaha (TSBs) wanda ya dace da ƙira, ƙirar, da girman injin abin hawa. Alamomin da aka adana da lambobin dole su yi daidai. Samun TSB mai dacewa zai taimaka muku ƙwarai a cikin ganewar ku.

Sakamakon ganina na lambar P2109 galibi yana farawa tare da dubawa na gani na duk wayoyi da masu haɗin haɗin da ke da alaƙa da tsarin. Zan kuma duba bawul ɗin maƙera don alamun ƙirar carbon ko lalacewa. Haɗin carbon da ya wuce kima wanda ke sa jikin maƙura ya buɗe a farawa yana iya haifar da adana lambar P2109. Tsaftace duk wani ajiyar carbon daga jikin maƙura bisa ga shawarwarin masana'anta kuma gyara ko maye gurbin wayoyi mara kyau ko aka gyara kamar yadda ya cancanta, sannan sake gwada tsarin DBW.

Kuna buƙatar na'urar sikirin bincike, volt / ohmmeter na dijital (DVOM), da ingantacciyar hanyar bayanan abin hawa don tantance wannan lambar daidai.

Sannan haɗa na'urar daukar hotan takardu zuwa tashar binciken abin hawa kuma dawo da duk DTC da aka adana. Rubuta su idan kuna buƙatar bayani daga baya a binciken ku. Har ila yau adana duk wani bayanan daskarewa da aka haɗa. Waɗannan bayanan na iya zama masu taimako, musamman idan P2109 ba ta daɗewa. Yanzu share lambobin kuma gwada fitar da abin hawa don tabbatar an share lambar.

Idan an share lambar nan da nan, ana iya gano ƙarfin wuta 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 akan kowane siginar siginar firikwensin. Don samun bayanai na ainihi daga DVOM, haɗa madaidaicin gwajin gwaji zuwa gubar siginar da ta dace da gwajin ƙasa zuwa kewayen ƙasa, sannan ku kalli nunin 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. Voltage yawanci yana fitowa daga rufewar 5V mai rufewa zuwa maƙogwaro mai buɗewa na 4.5V, amma bincika tushen bayanan abin hawan ku don ainihin takamaiman bayani. 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.

Gyara ko maye gurbin da'irar tsarin kamar yadda ya cancanta.

Ana iya tuhumar kuskuren shirye -shiryen PCM ko PCM idan an bincika duk na'urori masu auna sigina da da'irar tsarin.

Wasu masana'antun suna buƙatar jujjuyawar motar, matattarar mai kunnawa, da duk firikwensin matsayin maƙura don maye gurbin su gaba ɗaya.
