P245E Particulate Filter B Kuthamanga kwa Sensor Circuit

Mapepala a OBD-II DTC

Dizilo Particulate Sefani B Anzanu SENSOR Dera

Kodi izi zikutanthauzanji?

Izi Diagnostic Trouble Code (DTC) ndi njira yofalitsira, zomwe zikutanthauza kuti imagwira ntchito pagalimoto zonse kuyambira 1996 (Ford, Dodge, GMC, Chevrolet, Mercedes, VW, etc.). Ngakhale ndizachilengedwe, njira zowongolera zimatha kusiyanasiyana kutengera mtundu / mtundu.

Ngati galimoto yanu ikuwonetsa injini posachedwa ndi chizindikiritso cha P245E, powertrain control module (PCM) yawona kuti magetsi akuyenda pamagetsi a dizilo (DPF), omwe amatchedwa B. Mwachidziwikire, nambala iyi iyenera kuwonetsedwa mumagalimoto okhala ndi injini ya dizilo.

DPF yapangidwa kuti ichotse magawo makumi asanu ndi anayi mphambu anayi a mpweya (mwaye) wa tinthu tating'onoting'ono tomwe timatulutsa mpweya wa dizilo. Soti nthawi zambiri imagwirizanitsidwa ndi utsi wakuda womwe umatuluka mumafuta omwe injini ya dizilo ikamathamanga kwambiri. DPF imakhala mchipinda chazitsulo chomwe chimafanana ndi chosinthira chosintha. Ili kumtunda kwa chosinthira chothandizira ndi / kapena msampha wa NOx. Pomwe tinthu tating'onoting'ono tomwe tagwidwa mu DPF elementi, tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono titha kudutsa. DPF imagwiritsa ntchito mitundu ingapo yazinthu zoyambira kuti ikole msuzi ndikudutsa mpweya wotulutsa injini. Izi zikuphatikiza mapepala, ulusi wachitsulo, ulusi wa ceramic, ulusi wamakona a silicone, ndi ulusi wa wall wa cordierite.

Cordierite ndi mtundu wa zosefera za ceramic komanso mtundu wodziwika bwino wa fiber womwe umagwiritsidwa ntchito muzosefera za DPF. Ndiotsika mtengo komanso ali ndi mawonekedwe abwino kwambiri osefera. Tsoka ilo, cordierite imakhala ndi vuto losungunuka pa kutentha kwambiri, zomwe zimapangitsa kuti ikhale yolephera ikagwiritsidwa ntchito m'masefa ang'onoang'ono.

Mtima wa fyuluta iliyonse ndi chinthu chosefera. Utsi wa injini ukadutsa pa chinthucho, tinthu tambiri ta mwaye timatsekeredwa pakati pa ulusiwo. Mwaye ukachulukirachulukira, mphamvu ya mpweya wotulutsa mpweya imachulukanso. Muye wokwanira ukachuluka (ndipo mphamvu ya utsi yafika pa digiri yokonzedwa), chinthu chosefera chiyenera kusinthidwanso kuti mpweya wotulutsa mpweya upitirire kudutsa mu DPF.

Machitidwe ogwiritsira ntchito DPF amasintha mwadzidzidzi. Mwanjira ina, PCM idakonzedwa kuti ijowine mankhwala (kuphatikiza koma osakwanira dizilo ndi kutulutsa madzi) mumipweya yotulutsa pakadutsa nthawi. Izi zimapangitsa kuti kutentha kwa mpweya kutuluke ndikukwera maotoyi atenthedwa; kuwamasula ngati ma nitrojeni ndi ma ayoni a oxygen.

Njira yomweyi imagwiritsidwanso ntchito m'machitidwe a DPF, koma imafuna kuti eni ake agwire nawo (nthawi zina) wokonzanso woyenerera. Pambuyo pobwezeretsa, zimatha kutenga maola angapo. Makina ena obwezeretsa opanda pake amafuna kuti DPF ichotsedwe mgalimoto ndikuthandizidwa ndi makina apadera omwe amaliza ntchitoyi ndikuchotsa mwaye tinthu tating'onoting'ono. Ma soot atachotsedwa mokwanira, DPF imawerengedwa kuti yasinthidwa ndipo kuthamanga kwa utsi kuyenera kuyankha moyenera.

Nthawi zambiri, makina opanikizira a DPF amaikidwa mchipinda cha injini, kutali ndi DPF. Imayang'anira kuthamanga kwakumbuyo kwa mpweya wotulutsa utsi usanalowe mu fyuluta ya tinthu. Izi zimatheka ndi (imodzi kapena zingapo) zotsekemera za silicone zomwe zimalumikizidwa ndi DPF (pafupi ndi polowera) ndi DPF sensor sensor.

PCM ikazindikira vuto lakukhathamira komwe sikuli malinga ndi zomwe wopanga adachita, kapena kulowetsa kwamagetsi kuchokera ku DPF B sensor sensor kupitilira malire omwe adakonzedweratu, nambala ya P245E idzasungidwa ndipo nyali ya injini yothandizira idzawala posachedwa.

Zizindikiro ndi kuuma kwake

Zomwe zimasungidwa nambala iyi zitha kuwononga makina amkati kapena mafuta ndipo ziyenera kukonzedwa nthawi yomweyo. Zizindikiro za chikhombo cha P245E zitha kuphatikizira izi:

• Utsi wakuda wochuluka kuchokera ku chitoliro cha utsi
• Kuchepetsa ntchito ya injini
• Kuchuluka kwa kutentha kwa injini
• Kutentha kwapamwamba kwambiri

zifukwa

Zifukwa zomwe zingakhazikitsire nambala iyi:

• Makina osungira madzi a dizilo alibe.
• Chinyezi Cholakwika cha Dizilo
• Wopunduka DPF kuthamanga sensor
• Machubu otsekemera a DPF atsekedwa
• Dera lotseguka kapena lalifupi mu dera la DPF lotsekemera la B
• Kukonzanso Kwachisawawa kwa DPF
• Opanda ntchito DPF dongosolo lokonzanso

Njira zowunikira ndikukonzanso

Malo oyambira nthawi zonse amayang'ana ma bulletins aukadaulo (TSB) pagalimoto yanu. Vuto lanu limatha kukhala vuto lodziwika bwino lokonzedwa ndi wopanga ndipo limatha kukupulumutsirani nthawi ndi ndalama mukamayesa kusaka.

Kuti mupeze nambala ya P245E, mufunika chosakira matenda, volt digital / ohmmeter, ndi buku lothandizira kuchokera kwa wopanga. Thermometer ya infrared imatha kukhalanso yothandiza.

Nthawi zambiri ndimayamba kupeza matenda anga poyang'ana ndi zingwe zolumikizira ndi zolumikizira. Ndikadasamala kwambiri pa zingwe zomwe zimayendetsedwa pafupi ndi zida zotentha komanso m'mbali mwake. Onani malo opangira batri ndi batri panthawiyi ndikuwona zomwe jenereta yatulutsa.

Kenako ndidalumikiza sikani ndikupeza ma code onse osungidwa ndikuwumitsa chimango. Ndikulemba izi kuti ndidzagwiritse ntchito mtsogolo. Izi zitha kubwera mosavuta ngati nambala iyi ikhala yosasintha. Tsopano chotsani ma code ndikuyesa kuyendetsa galimotoyo.

Ngati codeyo ikukhazikitsanso nthawi yomweyo, onetsetsani kuti madzi a dizilo amatha kutulutsa madzi (ngati alipo) ndi amtundu woyenera. Chifukwa chofala kwambiri kuti code iyi imasungidwa ndikusowa kwa madzi a dizilo otulutsa madzi. Popanda mtundu woyenera wamafuta a injini ya dizilo, DPF siyingakonzedwenso bwino, zomwe zingayambitse kukakamizidwa kwa utsi.

Onaninso buku lazopanga la wopanga kuti mupeze malangizo amomwe mungayesere kachipangizo kokakamiza ka DPF pogwiritsa ntchito DVOM. Ngati sensa singakwaniritse zomwe wopanga akufuna kukana, ziyenera kusinthidwa. Ngati sensa ili bwino, yang'anani mapiritsi a DPF kuthamanga kwa zotchinga ndi / kapena zopuma. Sambani kapena sinthani ma payipi ngati kuli kofunikira. Makina otentha otentha a silicone ayenera kugwiritsidwa ntchito.

Ngati sensa ndiyabwino ndipo mizere yamagetsi ndiyabwino, yambani kuyesa mabwalo amachitidwe. Chotsani ma module onse oyanjanitsidwa musanayesedwe kukana ndi / kapena kupitiriza ndi DVOM. Konzani kapena sinthani ma circuits otseguka kapena afupikitsa ngati kuli kofunikira.

Zowonjezera zowonjezera:

• Ngati ma hoses a DPF pressure sensor asungunuka kapena kung'ambika, kungakhale koyenera kuyambiranso pambuyo pobwezeretsa.
• Funsani kwa eni ake / buku lothandizira kuti mudziwe ngati galimoto yanu ili ndi makina obwezeretsanso a DPF kapena osachita chilichonse.
• Ma doko otsekeka a sensor ndi machubu otsekeka a sensor ndiofala

Zokambirana zokhudzana ndi DTC

• Pakadali pano palibe mitu yofananira m'mabwalo athu. Tumizani mutu watsopano pamsonkhano tsopano.

Mukufuna thandizo lina ndi code p245E?

Ngati mukufunabe thandizo ndi DTC P245E, lembani funso mu ndemanga pansipa pamutuwu.

ZINDIKIRANI. Izi zimaperekedwa kuti zidziwitse zokha. Sikuti tizigwiritsa ntchito ngati malingaliro okonzanso ndipo sitili ndi udindo pazomwe mungachite pagalimoto iliyonse. Zomwe zili patsamba lino ndizotetezedwa ndi zovomerezeka.
