P2452 - Dizilo Particulate Filter Pressure Sensor Circuit

Kodi vuto la P2452 limatanthauza chiyani?

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 iwonetsa injini posachedwa pomwe ikutsatiridwa ndi nambala ya P2452, gawo loyendetsa mphamvu ya powertrain (PCM) lazindikira kusayenda bwino kwa magetsi pamagetsi a DPF, omwe amadziwika kuti A. Mwachidziwikire, nambala iyi iyenera kungoperekedwa pagalimoto 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 sikungafanane ndi zomwe wopanga adachita, kapena magetsi ochokera ku DPF A sensor sensor ipitilira malire omwe adakonzedwa, nambala ya P2452 idzasungidwa ndipo nyali ya injini yothandizira iwala posachedwa.
