Mene ne wannan yake nufi?

Wannan sigar Lambar Matsalar Bincike ce (DTC) wacce ta dace da yawancin motocin OBD-II (1996 da sabuwa). Wannan na iya haɗawa amma ba'a iyakance ga VW, Kia, Peugeot, BMW, Cadillac, Holden, Honda, Ford, da dai sauransu Duk da yanayin gabaɗaya, ainihin matakan gyara na iya bambanta dangane da shekarar ƙira, yin, samfuri da watsawa.

Lambar P2231 da aka adana tana nufin tsarin sarrafa wutar lantarki (PCM) ya gano gajeriyar a cikin firikwensin iskar oxygen (O2) don lambar bankin injin lamba ɗaya. Bank one shine rukunin injin da ke ɗauke da silinda lamba ɗaya. Sensor 1 yana gano firikwensin sama (pre-sensor) a cikin tsarin firikwensin uku (saɓanin tsarin firikwensin huɗu).

PCM yana amfani da shigarwar daga firikwensin iskar oxygen (HO2S) don sa ido kan abubuwan oxygen a cikin iskar gas don kowane bankin injin, da kuma ingancin mai jujjuyawar.

An gina na'urori masu auna iskar oxygen ta amfani da wani abin firikwensin zirconia wanda yake a tsakiyar gidan ƙarfe mai iska. Ana siyar da ƙananan wayoyin lantarki na platinum tsakanin abubuwan da ke ji da wayoyi a cikin haɗin haɗin haɗin firikwensin oxygen. Haɗin haɗin haɗin firikwensin O2 yana haɗawa zuwa cibiyar sadarwar mai sarrafawa (CAN), wanda ke haɗa jigon firikwensin oxygen zuwa mai haɗa PCM.

Kowane HO2S yana da zaren (ko studs) a cikin bututu mai ƙarewa ko yawa. An sanya shi don abin da ke ji yana kusa da tsakiyar bututu. Iskar gas mai sharar gida tana barin ɗakin ƙonewa (ta hanyar yawan shaye -shaye) kuma ta bi ta cikin tsarin shaye -shaye (gami da masu jujjuyawa); yana zubowa akan abubuwan firikwensin oxygen. Iskar gas tana shiga firikwensin oxygen ta hanyoyin iska da aka ƙera ta musamman a cikin gidan ƙarfe kuma tana zagayawa a cikin abubuwan da ake ji. Iskar da aka ɗora ta cikin ramukan waya a cikin gidan firikwensin ya cika ƙaramin ɗakin a tsakiyar firikwensin. Iska mai zafi (a cikin ƙaramin ɗakin) yana haifar da ions oxygen don samar da makamashi, wanda PCM ya sani azaman ƙarfin lantarki.

Bambance -bambancen dake tsakanin adadin 2 a cikin iskar yanayi da yawan adadin sinadarin oxygen a cikin shaye -shaye na haifar da ions mai zafi na oxygen a cikin HO2S ya yi tsalle cikin sauri da ɓata lokaci daga wani farantin platinum zuwa na gaba. Yayin da ions iskar oxygen ke motsawa tsakanin yadudduka na platinum, ƙarfin wutar lantarki na HO2S yana canzawa. PCM yana ganin waɗannan canje -canje a cikin ƙarfin fitarwa na HO2S yayin canje -canje a cikin iskar oxygen a cikin iskar gas.

Abubuwan fitarwa na wutar lantarki daga HO2S sun yi ƙasa lokacin da ƙarin iskar oxygen ke cikin shaye -shaye (yanayin durƙushewa) kuma mafi girma lokacin da ƙarancin iskar oxygen ke cikin shaye -shaye (yanayin arziki). Wannan ɓangaren HO2S yana amfani da ƙaramin ƙarfin lantarki (ƙasa da volt ɗaya).

A wani sashe na firikwensin, HO2S yana da zafi ta amfani da ƙarfin batir (12 volts). Lokacin da zafin injin ya yi ƙasa, ƙarfin batirin yana zafi HO2S don ya fara sa ido kan iskar oxygen a cikin iskar gas da sauri.

Idan PCM ya gano matakin ƙarfin lantarki wanda baya cikin sigogi masu karɓa, za a adana P2231 kuma Lamp Indicator Lamp (MIL) na iya haskakawa. Yawancin motocin za su buƙaci da'irar ƙonewa da yawa (akan gazawa) don kunna hasken faɗakarwa.

Menene tsananin wannan DTC?

Taƙaitaccen kewaye a cikin HO2S na iya haifar da ƙarancin aikin injiniya da matsaloli daban -daban na sarrafawa. Lambar P2231 yakamata a rarrabe ta da mahimmanci kuma a gyara ta da wuri -wuri.

Menene wasu alamomin lambar?

Alamomin lambar matsala P2231 na iya haɗawa da:

• Kuskuren shirye -shiryen PCM ko PCM

Menene wasu matakai don warware matsalar P2231?

Cikakken ganewar lambar P2231 yana buƙatar na'urar binciken cuta, volt / ohmmeter na dijital (DVOM), da amintaccen bayanin abin hawa.

Haɗa na'urar daukar hotan takardu zuwa tashar binciken abin hawa kuma sami duk lambobin da aka adana da kuma daskare bayanan firam ɗin daidai. Za ku so ku rubuta wannan bayanin kawai idan lambar ta juya ta kasance mai shiga tsakani. Sannan share lambobin kuma gwada fitar da abin hawa. A wannan lokacin, ɗayan abubuwa biyu za su faru. Ko dai an share P2231 ko PCM ya shiga yanayin shirye.

Idan lambar ba ta wuce -wuri ba kuma PCM ta shiga yanayin shirye, yana iya zama da wahala a gane asali. Sharuɗɗan da suka kai ga adana P2231 na iya buƙatar yin muni kafin a iya yin cikakken bincike. Idan an share lambar, ci gaba da bincike.

Ana iya samun ra'ayoyin fuskokin mai haɗawa, zane -zane mai haɗawa, shimfidar ɓangarori, zane -zanen waya, da zane -zanen bincike (masu alaƙa da lambar haɗin gwiwa da abin hawa) ta amfani da tushen bayanan abin hawan ku.
