Menene ma'anar lambar matsala P2237?

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 shi ba, Mazda, VW, Acura, Kia, Toyota, BMW, Peugeot, Lexus, Audi, da dai sauransu Duk da yanayin gabaɗaya, ainihin matakan gyara na iya bambanta dangane da shekarar ƙira, iri, model da watsawa.

Lambar P2237 da aka adana tana nufin cewa tsarin sarrafa wutar lantarki (PCM) ya gano ingantacciyar rashin daidaituwa a halin yanzu 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 shine babban firikwensin (pre). Ingantacciyar kewayawar sarrafawa ta yanzu ita ce ƙananan ƙarfin lantarki.

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 P2237 kuma Lamp Indicator Lamp (MIL) na iya haskakawa. Yawancin motocin za su buƙaci da'irar ƙonewa da yawa (akan gazawa) don kunna hasken faɗakarwa.
