P0239 - turbocharger kulimbikitsa kachipangizo B dera kulephera

P0239 - Kufotokozera kwaukadaulo kwa code yolakwika ya OBD-II

Turbocharger Boost Sensor B Kusokonekera kwa Circuit

Kodi code P0239 imatanthauza chiyani?

Code P0239 ndi code yokhazikika ya OBD-II yomwe imayambika pamene Engine Control Module (ECM) iwona kusiyana pakati pa mphamvu yowonjezera mphamvu ya B ndi manifold pressure sensor sensor (MAP) pamene injini ikuyenda ndi mphamvu zochepa komanso mphamvu ya turbocharger iyenera. pa zero..

Zizindikirozi ndizofala pakupanga ndi mitundu yonse yamagalimoto, ndipo zikuwonetsa zovuta ndi kukakamiza kwa turbocharger. Komabe, njira zodziwira zenizeni zimatha kusiyanasiyana malinga ndi mtundu wagalimoto.

Zizindikiro za OBD siziwonetsa vuto linalake, koma thandizani katswiri kudziwa malo omwe angayang'ane chomwe chayambitsa vutoli.

Momwe supercharging (induction induction) imathandizira magwiridwe antchito

Turbocharger amapereka mpweya wochuluka ku injini kuposa momwe injiniyo imatha kulowetsamo nthawi zonse. Kuwonjezeka kwa mpweya wobwera, kuphatikizapo mafuta ochulukirapo, kumathandizira kuwonjezereka kwa mphamvu.

Nthawi zambiri, turbocharger imatha kuonjezera mphamvu ya injini ndi 35 mpaka 50 peresenti, ndi injini yopangidwa kuti igwire turbocharging. Zigawo za injini zokhazikika sizinapangidwe kuti zizitha kupirira katundu wopangidwa ndi mtundu uwu wa jakisoni wokakamizidwa.

Ma Turbocharger amawonjezera mphamvu zamagetsi popanda kukhudza chuma chamafuta. Amagwiritsa ntchito mpweya wotulutsa mpweya kuti ayambitse turbo, kotero mutha kuganiza kuti ndi mphamvu yowonjezera popanda mtengo wowonjezera. Komabe, akhoza kulephera mwadzidzidzi pazifukwa zosiyanasiyana, kotero ngati pali vuto ndi turbocharger, tikulimbikitsidwa kukonza mwamsanga. Ndi injini ya turbocharged, kulephera kwa turbocharger kumatha kukulitsa mkhalidwewo chifukwa cha kuchuluka kwa mpweya wothinikizidwa.

Ndikofunikira kukumbukira kuti injini yokhazikika ya turbocharged sayenera kusinthidwa ndikuwonjezera kuthamanga kwamphamvu. Kutumiza kwamafuta ndi ma valvu amapindika nthawi yama injini ambiri salola kuti agwire ntchito mothamanga kwambiri, zomwe zitha kuwononga injini kwambiri.

Chidziwitso: DTC iyi ndi yofanana ndi P0235, yomwe imalumikizidwa ndi Turbo A.

Kodi zizindikiro za vuto P0239 ndi chiyani?

Kuwala kwa Check Engine kumawunikira DTC ikayika. Ma module a turbo atha kuyimitsidwa ndi wowongolera injini, zomwe zimapangitsa kutaya mphamvu pakuthamanga.

Zizindikiro za nambala ya P0239 ndi:

1. Khodi ya P0239 ikuwonetsa vuto pagawo lowongolera, lomwe mwina limatsagana ndi ma code owonjezera okhudzana ndi magawo ena adera.
2. Kutaya kwa injini mathamangitsidwe.
3. Miyezo yamphamvu yolimbikitsira imatha kukhala yosiyana: zosakwana mapaundi 9 kapena kupitilira mapaundi 14, zomwe ndi zachilendo.
4. Phokoso lachilendo monga kuyimba mluzu kapena kunjenjemera kochokera pa turbocharger kapena mapaipi.
5. Khodi yomveka yogogoda yomwe ikuwonetsa kuphulika chifukwa cha kutentha kwamutu kwa silinda.
6. General kutayika kwa mphamvu ya injini.
7. Utsi kuchokera payipi yotulutsa utsi.
8. Makandulo akuda.
9. Kutentha kwakukulu kwa injini pa liwiro lakuyenda.
10. Kulira kumamveka kuchokera kwa fan.

Injini Yoyang'ana idzatsegulidwa ndipo code idzalembedwa ku ECM pamene izi sizikuyenda bwino, zomwe zimapangitsa kuti turbocharger azimitsa ndikuchepetsa mphamvu ya injini panthawi yothamanga.

Zotheka

Zomwe zimayambitsa vuto la P0239 zitha kuphatikiza:

1. Tsegulani dera la turbocharger pressure sensor yokhala ndi phindu lamkati.
2. Kuwonongeka kwa turbocharger pressure sensor Cholumikizira chomwe chimayambitsa kuzungulira kotseguka.
3. Kufupikitsa kwa ma waya pakati pa sensor ya boost pressure ndi module control injini (ECM).

Zinthu izi zitha kupangitsa kuti kukakamiza kowonjezereka kusayendetsedwe bwino, komwe kumatha kulumikizidwa ndi zovuta zingapo, kuphatikiza kutayikira kwa vacuum, zovuta zosefera mpweya, zovuta zowonongeka, zovuta zoperekera mafuta a turbo, masamba owonongeka a turbine, zovuta zosindikizira mafuta, ndi zina. Kuphatikiza apo, pakhoza kukhala mavuto ndi kulumikizana kwamagetsi ndi masensa.

Momwe mungadziwire vuto la P0239?

Kuzindikira mavuto a turbo nthawi zambiri kumayamba ndi zomwe wamba, ndipo kugwiritsa ntchito zida zosavuta monga vacuum gauge ndi dial gauge kumatha kukhala kothandiza. M'munsimu ndikutsatira njira zodziwira matenda:

1. Onetsetsani kuti injini ikuyenda bwino, palibe ma spark plugs oyipa, ndipo palibe ma code okhudzana ndi sensor yogogoda.
2. Ndi kuzizira kwa injini, yang'anani kulimba kwa zomangira pamalo opangira turbine, intercooler ndi throttle body.
3. Yesani kugwedeza turbine panjanji yotuluka kuti muwonetsetse kuti yalumikizidwa bwino.
4. Yang'anani kuchuluka kwa madzi olowera ngati akutuluka, kuphatikiza mapaipi a vacuum.
5. Chotsani chowotchera chowongolera ku zinyalala ndikugwiritsira ntchito valavu pamanja kuti muzindikire zovuta zomwe zingachitike.
6. Ikani choyezera cha vacuum mu chopanda chomwe mumalowetsamo ndikuyang'ana vacuum ndi injini ikuyenda. Popanda ntchito, vacuum iyenera kukhala pakati pa mainchesi 16 ndi 22. Ngati ili yochepera 16, izi zitha kuwonetsa chosinthira chothandizira cholakwika.
7. Wonjezerani liwiro la injini kufika pa 5000 rpm ndikumasula pompopompo mukuwona kukakamiza kwa geji. Ngati kupanikizika kuli kwakukulu kuposa mapaundi a 19, vuto likhoza kukhala ndi valve yodutsa. Ngati phindu silisintha pakati pa 14 ndi 19 lbs, chifukwa chake chingakhale vuto ndi turbo yokha.
8. Muziziziritsa injini ndikuyang'ana turbine, chotsani chitoliro chotulutsa ndikuyang'ana momwe ma turbine amkati akuwonongeka, masamba opindika kapena osowa, komanso mafuta mu turbine.
9. Yang'anani mizere yamafuta kuchokera pa chipika cha injini kupita ku turbine center bearing ndi mzere wobwerera ngati akutuluka.
10. Ikani chizindikiro choyimba pamphuno ya turbine yotulutsa ndikuwona sewero lomaliza la shaft ya turbine. Ngati sewero lomaliza ndi lalikulu kuposa mainchesi 0,003, zitha kuwonetsa vuto ndi pakati.

Ngati turbo ikugwira ntchito bwino mutatha kuyesa izi, sitepe yotsatira ingakhale kuyang'ana mphamvu yowonjezera ndi waya pogwiritsa ntchito volt / ohmmeter. Yang'anani zizindikiro pakati pa sensa ndi unit control unit. Ndikofunika kukumbukira kuti si ma code onse a OBD2 omwe amatanthauziridwa chimodzimodzi ndi opanga osiyanasiyana, chifukwa chake muyenera kuwona bukhu loyenera kuti mudziwe zambiri.

Zolakwa za matenda

Kuti mupewe matenda olakwika, tsatirani malangizo osavuta awa:

1. Yang'anani payipi ya sensor ya boost pressure for blockages ndi kinks.
2. Onetsetsani kuti kugwirizana kwa magetsi kwa sensa ndi kotetezeka komanso kuti palibe kutayikira kapena kinks muzitsulo zokakamiza.

Ndi kukonza kotani komwe kungakonze P0239?

Ngati sensor yowonjezera situmiza deta yolondola ku ECM:

1. Bwezeraninso sensor yowonjezera.
2. Yang'anani ma turbo sensor hoses ndi zolumikizira za kinks kapena blockages ndikukonza kapena m'malo ngati kuli kofunikira.
3. Konzani mawaya ku sensa kapena sinthani cholumikizira kuti mubwezeretse ntchito yabwinobwino.

Kodi vuto la P0239 ndi lalikulu bwanji?

Kuchepa kwamphamvu mu gawo la sensa kumatha kuyambitsa kutentha kwamkati kwa ECM, makamaka ngati voteji yafupipafupi ndi yayikulu kuposa 5 V.

Ngati ECM ikuwotcha, pali ngozi yoti galimotoyo singayambe ndipo ikhoza kuyimitsa.
