Bayanan Bayani na OBD-II

Manifold Absolute Matsi - Turbocharger/Supercharger B Sensor Ratio

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 Land Rover (Range Rover, Discovery), Ford, Chevrolet, Mazda, Dodge, Peugeot, Saab, Toyota, da sauransu.

Kodayake gabaɗaya, madaidaitan matakan gyara na iya bambanta dangane da shekarar ƙirar, ƙirar, ƙirar, da tsarin watsawa.

Idan abin hawa na OBD-II ɗinku ya adana lambar P023E, yana nufin cewa tsarin sarrafa wutar lantarki (PCM) ya gano rashin daidaituwa a cikin siginar da aka haɗa tsakanin firikwensin matsi mai yawa (MAP) da firikwensin haɓaka turbocharger / supercharger, wanda shine alamar "B" ...

Harafin "B" yana nuna takamaiman firikwensin haɓakawa a cikin tsarin wanda zai iya amfani da firikwensin haɓakawa da yawa a wurare daban -daban. Tuntuɓi tushen bayanan abin hawa abin dogara don sanin ainihin abin da firikwensin B ke nufi (don abin hawa da ake tambaya). Wannan lambar ta shafi motocin da ke sanye da ingantattun na'urorin samar da iska. Na'urorin tilasta iska sun haɗa da turbochargers da blowers.

MAP firikwensin yana ba PCM siginar ƙarfin lantarki wanda ke nuna yawa ko matsin lamba na iskar da yawa. Ana karɓar siginar ƙarfin lantarki (PCM) a cikin raka'a kilopascals (kPa) ko inci na mercury (Hg). A wasu motocin, ana maye gurbin matsin lamba barometric, wanda aka auna a cikin irin wannan kari.

Turbocharger / supercharger yana haɓaka firikwensin matsin lamba (wanda aka yiwa lakabi da B) yana iya zama mai ƙira iri ɗaya ga firikwensin MAP. Yana lura da ƙimar iska (haɓaka matsin lamba) a cikin bututun ci na turbocharger / supercharger kuma yana ba PCM siginar wutar lantarki mai dacewa.

Za a adana lambar P023E kuma Lamp Indicator Lamp (MIL) na iya haskakawa idan PCM ta gano siginar wutar lantarki tsakanin firikwensin MAP da turbocharger / supercharger sensor B waɗanda suka bambanta fiye da matakin da aka tsara. MIL na iya buƙatar hawan wuta mai yawa (tare da gazawa) don haskakawa.

Menene tsananin wannan DTC?

Gabaɗaya aikin injiniya da tattalin arzikin mai na iya yin illa ga yanayin da ke ba da gudummawa ga lambar P023E. Ya kamata a kasafta shi da nauyi.

Menene wasu alamomin lambar?

Alamomin lambar matsala P023E na iya haɗawa da:

• Rage ƙarfin injin
• Wadataccen wadatacce ko rashin ƙarfi
• Jinkirta fara injin (musamman sanyi)
• Rage ingancin man fetur

Mene ne wasu abubuwan da ke haifar da lambar?

Dalilin wannan P023E DTC na iya haɗawa da:

• Mabuɗin MAP / Turbocharger / Boost sensor B
• Buɗewa ko gajere kewaye a cikin wayoyi ko mai haɗa firikwensin MAP / turbocharger / supercharger B
• Rashin injin
• Intercooler mai iyaka
• Kuskuren shirye -shiryen PCM ko PCM

Menene wasu matakai don warware matsalar P023E?

Kafin yunƙurin gano lambar P023E, da farko zan fara samun damar yin amfani da na'urar sikirin bincike, volt / ohmmeter na dijital (DVOM), ma'aunin injin na hannu, da ingantacciyar hanyar bayanan abin hawa. Binciken kowane lambar da ke da alaƙa da MAP firikwensin yakamata ya haɗa da tabbatar da cewa injin yana samar da isasshen sarari. Ana iya yin wannan ta amfani da ma'aunin injin.

Binciken gani na duk MAP / turbocharger / supercharger firikwensin wayoyi da masu haɗawa suna da kyau muddin babu cikas a cikin intercooler kuma matatar iskar tana da tsabta. Gyara idan ya cancanta. Sannan na haɗa na'urar daukar hotan takardu zuwa tashar binciken mota kuma na sami duk lambobin da aka adana da daskare bayanan firam. Za a iya kwatanta bayanan firam ɗin daskarewa azaman hoto na ainihin yanayin da ya faru yayin lahani wanda ya haifar da lambar P023E da aka adana. Ina so in rubuta wannan bayanin saboda yana iya taimakawa cikin bincike. Yanzu share lambobin kuma gwada fitar da abin hawa don tabbatar an share lambar.

Idan wannan:

• Duba kowane MAP / turbocharger / supercharger yana haɓaka firikwensin matsa lamba ta amfani da DVOM da tushen bayanan abin hawan ku.
• Sanya DVOM akan saitin Ohm kuma gwada firikwensin yayin da aka cire su.
• Tuntuɓi tushen bayanan abin hawa don ƙayyadaddun gwajin ɓangaren.
• MAP / turbocharger / haɓaka firikwensin da ba su cika ƙayyadaddun masana'anta ba dole ne a maye gurbin su.

Idan duk firikwensin sun hadu da ƙayyadaddun masana'anta:

• Duba ƙarfin ƙarfin tunani (yawanci 5V) da ƙasa a cikin masu haɗin firikwensin.
• Yi amfani da DVOM kuma haɗa madaidaicin gwajin gwaji zuwa fil ɗin ƙarfin wutar lantarki na mai haɗa firikwensin da kuma gwajin gwajin mara kyau zuwa fil ɗin mai haɗawa.

Idan ka sami ƙarfin lantarki da ƙasa:

• Haɗa firikwensin kuma bincika da'irar siginar firikwensin tare da injin yana aiki.
• Bi ma'aunin zafin jiki da ƙarfin wutar lantarki da aka samo a cikin tushen bayanan abin hawa don sanin ko na'urori masu auna sigina suna aiki yadda yakamata.
• Dole ne a maye gurbin firikwensin da ba su nuna takamaiman matakin ƙarfin lantarki na masana'anta (gwargwadon yawan matsin lamba da turbocharger / supercharger haɓaka matsa lamba).

Idan da'irar siginar firikwensin tana nuna daidai matakin ƙarfin lantarki:

• Duba da'irar sigina (don firikwensin da ake tambaya) a mai haɗa PCM. Idan akwai siginar firikwensin a mai haɗa firikwensin amma ba a mai haɗin PCM ba, akwai kewaye mai buɗewa tsakanin ɓangarorin biyu.
• Gwada da'irar tsarin mutum ɗaya tare da DVOM. Cire haɗin PCM (da duk masu sarrafawa masu alaƙa) kuma bi tsarin bincike na bincike ko maɓallin haɗin haɗi don gwada juriya da / ko ci gaba da kewayawar mutum.

Idan duk MAP / turbocharger / supercharger yana haɓaka firikwensin matsa lamba da da'irori suna cikin ƙayyadaddun bayanai, yi zargin gazawar PCM ko kuskuren shirye -shiryen PCM.

• Duba Sabis na Sabis na Fasaha (TSB) don taimako tare da ganewar asali.

• A halin yanzu babu batutuwa masu alaƙa a cikin dandalin mu. Sanya sabon taken akan dandalin yanzu.

Kuna buƙatar ƙarin taimako tare da lambar P023E?

Idan har yanzu kuna buƙatar taimako tare da DTC P023E, 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.
