Turbocharger Boost Sensor B

Menene ma'anar lambar P0239?

Lambar P0239 ita ce ma'auni na OBD-II wanda ke haifar da lokacin da Module Control Engine (ECM) ya gano rashin daidaituwa tsakanin na'urar firikwensin ƙarfin ƙarfin B da manifold matsin lamba (MAP) karanta lokacin da injin ke gudana a mafi ƙarancin iko kuma matsa lamba turbocharger ya kamata. ba zero..

Waɗannan lambobin sun zama gama gari ga duk kera da samfuran motocin, kuma suna nuna matsaloli tare da ƙarfin ƙarfin turbocharger. Koyaya, ainihin matakan bincike na iya bambanta dangane da takamaiman ƙirar abin hawa.

Lambobin OBD ba su nuna takamaiman lahani ba, amma suna taimaka wa ƙwararren sanin yankin da zai nemi dalilin matsalar.

Yadda babban caji (tilastawa shigar) ke inganta aiki

Turbochargers suna isar da iska mai yawa ga injin fiye da injin ɗin da ke iya ɗauka a cikin yanayin al'ada. Ƙara yawan ƙarar iska mai shigowa, haɗe tare da ƙarin man fetur, yana taimakawa wajen karuwa a cikin wutar lantarki.

Yawanci, turbocharger na iya ƙara ƙarfin injin da kashi 35 zuwa 50 cikin ɗari, tare da injin ɗin da aka ƙera musamman don sarrafa turbocharging. Ba a tsara daidaitattun abubuwan injina don jure nauyin da irin wannan nau'in allurar iska ta tilastawa ke haifarwa ba.

Turbochargers suna ba da haɓaka mai mahimmanci a cikin wutar lantarki tare da kusan babu tasiri akan tattalin arzikin man fetur. Suna amfani da kwararar iskar gas don tayar da turbo, don haka za ku iya tunaninsa a matsayin ƙarin iko ba tare da ƙarin farashi ba. Duk da haka, suna iya kasa ba zato ba tsammani saboda dalilai daban-daban, don haka idan akwai matsala tare da turbocharger, ana bada shawara don gyara shi da sauri. Tare da injin turbocharged, gazawar turbocharger na iya cutar da yanayin sosai saboda girman iska mai ƙarfi.

Yana da mahimmanci a tuna cewa daidaitaccen injin turbocharged bai kamata a canza shi ta hanyar haɓaka ƙarfin haɓakawa ba. Isar da man fetur da madaidaicin lokacin bawul na yawancin injuna ba sa ba da izinin aiki a matsananciyar haɓakawa, wanda zai iya haifar da mummunar lalacewar injin.

Lura: Wannan DTC kusan yayi kama da P0235, wanda ke da alaƙa da Turbo A.

Menene alamun lambar matsala P0239?

Hasken Duba Inji yana haskaka lokacin da DTC ta saita. Mai sarrafa injin na iya kashe tsarin turbo, wanda ke haifar da asarar wutar lantarki yayin haɓakawa.

Alamomin lambar P0239 sun haɗa da:

1. Lambar P0239 tana nuna matsala a cikin da'irar haɓaka haɓakawa, mai yiwuwa tare da ƙarin lambobi masu alaƙa da wasu sassan da'irar.
2. Asarar hanzarin injin.
3. Ƙimar ma'aunin matsi na iya zama daga kewayon: ƙasa da fam 9 ko fiye da fam 14, wanda ba shi da kyau.

Za a kunna Injin Dubawa kuma za a rubuta lambar zuwa ECM lokacin da wannan rashin aiki ya faru, yana sa turbocharger ya kashe kuma ya rage ƙarfin injin yayin haɓakawa.

Dalili mai yiwuwa

Abubuwan da ke haifar da lambar matsala na P0239 na iya haɗawa da:

1. Buɗe da'ira na firikwensin matsa lamba na turbocharger tare da riba na ciki.
2. Lalacewar firikwensin matsa lamba na turbocharger Mai haɗawa yana haifar da buɗewar kewayawa.
3. Gajeren kayan aikin wayoyi tsakanin na'urar firikwensin ƙarfin ƙarfi da tsarin sarrafa injin (ECM).

Wadannan abubuwan na iya haifar da rashin sarrafa matsin lamba na haɓakawa, wanda za'a iya danganta shi da matsaloli da yawa masu yuwuwa, waɗanda suka haɗa da ɗigon ruwa, matsalolin tace iska, matsalolin sharar gida, matsalolin samar da mai na turbo, lalacewar injin injin injin, matsalolin hatimin mai, da sauran su. Bugu da kari, ana iya samun matsaloli tare da haɗin lantarki da na'urori masu auna firikwensin.

Yadda ake bincika lambar matsala P0239?

Gano matsalolin turbo yawanci yana farawa da zaɓuɓɓuka na gama gari, kuma yin amfani da kayan aiki masu sauƙi kamar ma'auni mai ƙima da ma'aunin bugun kira na iya yin tasiri sosai. A ƙasa akwai jerin matakan bincike:

1. Tabbatar cewa injin yana aiki akai-akai, babu mummunan tartsatsi, kuma babu lambobin da ke da alaƙa da firikwensin bugun.
2. Tare da sanyin injin, duba maƙunƙun matse a mashin injin turbine, intercooler da jikin magudanar ruwa.
3. Gwada jujjuya injin injin a kan fitilun waje don tabbatar da an haɗe shi amintacce.
4. Bincika nau'in abin sha don ɗigogi, gami da magudanar ruwa.
5. Cire lever actuator daga sharar gida kuma yi aiki da bawul da hannu don gano matsalolin daftarin aiki.
6. Shigar da injin ma'auni a cikin ɓangarorin da ke cikin nau'in abin sha kuma duba injin tare da aikin injin. A wurin aiki, injin ya kamata ya kasance tsakanin inci 16 zuwa 22. Idan bai wuce 16 ba, wannan na iya nuna kuskuren mai canza catalytic.
7. Ƙara saurin injin zuwa 5000 rpm kuma saki ma'aunin yayin lura da ƙarfin haɓakawa akan ma'aunin. Idan matsa lamba ya fi fam 19, matsalar na iya kasancewa tare da bawul ɗin kewayawa. Idan riba ba ta canza tsakanin 14 da 19 lbs, dalilin zai iya zama matsala tare da turbo kanta.
8. A sanyaya injin ɗin kuma duba injin ɗin, cire bututun da ke shayewa sannan a duba yanayin injin turbin ɗin na ciki don lalacewa, lanƙwasa ko ya ɓace, da mai a cikin injin injin.
9. Bincika layukan mai daga toshewar injin zuwa cibiyar injin turbine da layin dawowa don ɗigogi.
10. Shigar da alamar bugun kira akan hancin turbine mai fitarwa kuma duba wasan ƙarshen turbine. Idan wasan ƙarshe ya fi inci 0,003, yana iya nuna matsala tare da ɗaukar tsakiya.

Idan turbo yana aiki akai-akai bayan yin waɗannan gwaje-gwaje, mataki na gaba zai iya zama don duba firikwensin haɓakawa da wayoyi ta amfani da volt/ohmmeter. Bincika sigina tsakanin firikwensin da naúrar sarrafa injin. Yana da mahimmanci a tuna cewa ba duk lambobin OBD2 ke fassara iri ɗaya ta masana'antun daban-daban ba, don haka ya kamata ku tuntuɓi littafin da ya dace don cikakkun bayanai.

Kurakurai na bincike

Don hana rashin ganewar asali, bi waɗannan ƙa'idodi masu sauƙi:

1. Bincika bututun firikwensin ƙara matsa lamba don toshewa da kinks.
2. Tabbatar cewa haɗin wutar lantarki na firikwensin yana amintacce kuma cewa babu ɗigogi ko ƙirƙira a cikin bututun matsa lamba.

Menene gyara zai gyara lambar P0239?

Idan firikwensin haɓakawa baya aika madaidaicin bayanan matsa lamba zuwa ECM:

1. Sauya firikwensin haɓakawa.
2. Bincika hoses na firikwensin turbo da haɗi don kinks ko blockages da gyara ko maye gurbin su idan ya cancanta.
3. Gyara wayoyi zuwa firikwensin ko maye gurbin haɗin don maido da aiki na yau da kullun.

Yaya girman lambar matsala P0239?

Shortarancin wutar lantarki a cikin kewayen firikwensin na iya haifar da zafi na ciki na ECM, musamman idan gajeriyar wutar lantarki ta fi 5 V.

Idan ECM yayi zafi sosai, akwai haɗarin cewa abin hawa ba zai tashi ba kuma yana iya tsayawa.
