P2454 Diesel Particulate Filter Pressure Sensor Yakaderera Signal

OBD-II Dambudziko Code - P2454 - Datasheet

P2454 - Diesel Particulate Sefa A Pressure Sensor Circuit Yakaderera

Ko dambudziko rekodhi P2454 rinorevei?

Iyi Yekuongorora Dambudziko Kodhi (DTC) ndeye yakajairika kodhi yekutumira, zvinoreva kuti inoshanda kune dzese mota kubva 1996 (Ford, Dodge, GMC, Chevrolet, Mercedes, VW, nezvimwewo). Kunyangwe yakajairika, chaiwo matanho ekugadzirisa anogona kusiyana zvichienderana neiyo mhando / modhi.

Ndakaona kuti ndichichengeta kodhi P2454, iyo powertrain control module (PCM) yakaona yakaderera magetsi kuisa kubva kuDPF kumanikidza sensor wedunhu yakasarudzika A. Chete mota dzakashongedzerwa nedhiziri injini dzinofanira kuva nekodhi iyi.

Yakagadzirirwa kubvisa makumi mapfumbamwe muzana ecarbon (soot) zvidimbu kubva kune dhiziri dhizaini, DPF masisitimu ari kukurumidza kuve anoitika mune dhiziri mota. Injini dzedhiziri (kunyanya pakumhanyisa kwepamusoro) dzinoburitsa hutsi hutema hutema kubva kumagasi avo ekudzima. Inogona kuisirwa sosi. Iyo DPF inowanzo fanika senge isina kugadzikana kana inoshandura inoshandura, yakaiswa mudzimba dzesimbi uye iri kumusoro kwerwizi rwekuchinja (uye / kana NOx musungo). Ne dhizaini, yakakora soot particles yakavharirwa mune iyo DPF element, nepo zvidiki zvidiki (uye nezvimwe zvekuzadza macomputer) zvinogona kupfuura napo.

Anoverengeka eakemikari makomputa parizvino anoshandiswa kuteya makuru masosi masosi kubva kune dhiziri kupera magasi. Izvi zvinogona kusanganisira: mapepa emicheka, simbi tambo, ceramic fibers, silicone yemadziro tambo, uye cordierite madziro tambo. Ceramic-based cordierite ndiyo yakajairika fiber mhando inoshandiswa muDPF mafirita. Cordierite ine yakanakisa filtration hunhu uye haina mutengo wekugadzira. Nekudaro, cordierite inozivikanwa kuva nezvinetso nekupisa zvakanyanya pamatembiricha akanyanya, ichiita kuti ive panjodzi yekukanganisa mumotokari dzakashongedzerwa nepassive particulate firita masisitimu.

Pamwoyo we chero DPF chinhu chesefa. Makuru masosi masvosve akasungwa pakati peiyo tambo sezvo injini yekudzimisa gasi ichipfuura. Sezvo coarse soot particles inoungana, iyo yekumanikidza kumanikidza inowedzera. Mushure mekumanikidza gasi kumanikidza kwasvika padanho rakarongwa, chinhu chesefa chinofanira kugadziridzwa. Kuberekwa patsva kunobvumira gasi rekudzimisa kuti rirambe richipfuura neDPF uye nekuchengetedza chaiyo yekumanikidza yekumanikidza nhanho.

Anoshanda DPF masisitimu anozvigadzirisazve otomatiki. Mune iyi mhando yehurongwa, iyo PCM yakarongedzwa kujowa makemikari (kusanganisira asi asingagumiri kudhiziri uye nekuzadza fluid) muDPF panguva dzakarongwa. Iyi jekiseni inodzorwa nemagetsi inokonzeresa kuti tembiricha yemweya wekudzimisa ikwire, ichibvumira sosi yakasungirirwa kuti ipise uye isunungurwe senitrogen neion oxygen.

Passive DPF masisitimu akafanana (mune dzidziso) asi inoda imwe yekuisa kubva kune anoshanda. Kana yatanga, maitiro ekumutsiridza anogona kutora maawa akati wandei. Dzimwe mota dzinoda shopu inokodzera yekugadzirisa yekumutsiridza. Mamwe mamodheru akagadzirwa nenzira yekuti DPF inofanira kubviswa mumotokari uye ishandiswe nemuchina wakasarudzika unopedzisa maitiro uye unobvisa sosi inodzika.

Kana chete masosi masosi abviswa zvakakwana, iyo DPF inoonekwa seyakagadzirwazve. Mushure mekuzvarwa patsva, iyo yekumusoro yekumanikidza kumanikidza inofanira kudzokera kune inogamuchirwa nhanho.

Iyo DPF yekumanikidza sensor inowanzo gadzirirwa muchinjini cheinjini uye kure neDPF. Exhaust back pressure inotariswa neiyo sensor (kana ichipinda muDPF) uchishandisa silicone hoses (yakabatana neDPF uye DPF yekumanikidza sensor).

Iyo P2454 kodhi inochengetwa kana iyo PCM ikaona yekumanikidza yekumanikidza mamiriro ari pazasi pemagadzirirwo emugadziri, kana magetsi anopinza kubva kuDPF A yekumanikidza sensor iri pazasi yakarongedzwa miganho.

Zviratidzo uye kuomarara

Mamiriro ezvinhu anogona kukonzera kuti kodhi iyi irambe ichifanirwa kutorwa seinokurumidza sezvo inogona kukonzera kukuvara kune injini yemukati kana mafuta system. Zviratidzo zveP2454 kodhi inogona kusanganisira:

• Kuwedzera kweinjini tembiricha
• Pamusoro peyakajairika kutapisa tembiricha
• Yakaderedzwa injini kuita
• Pakazara injini kushanda kunogona kutanga kudzikira
• Hutsi hutema huzhinji hunogona kutanga kubuda mupombi yemotokari.
• Tembiricha yeinjini inogona kunge yakawandisa

Zvikonzero zveP2454 kodhi

Zvimwe zvikonzero zvekumisikidza kodhi iyi:

• Pedza kubuda
• DPF yekumanikidza sensor machubhu / hoses akavharwa
• Yakavhurika kana ipfupi dunhu muDPF yekumanikidza sensor Iyo wedunhu
• Yakaremara DPF yekumanikidza sensor
• Diesel exhaust fluid tank inogona kusununguka
• Dhiziri Isiri Yekuneta Urume
• DPF pressure sensor Circuit inogona kunge yakavhurika kana kusakwana
• Kusakwanisa kuvandudza DPF
• DPF regeneration system inogona kutadza

Kuongorora uye kugadzirisa maitiro

Nzvimbo yakanaka yekutanga nguva dzose yekutarisa technical Service Bulletins (TSB) kune yako chaiyo mota. Dambudziko rako rinogona kunge riri nyaya inozivikanwa neyakagadzirwa gadziriso-yakaburitswa gadziriso uye inogona kukusevha nguva nemari panguva yekugadzirisa matambudziko.

Dhijitari volt / ohmmeter, bhuku rebasa rekugadzira, uye yekuongorora scanner inodiwa kuti uongorore P2454 kodhi.

Tanga kuongororwa kwako nekuona nekuona akakodzera mahanesi uye zvinongedzo. Nyatsoongorora wiring iyo inofambiswa padhuze panopisa kupisa zvinhu uye / kana jagged micheto. Iyi nhanho inopera nekutarisa iyo inogadzira jenareta, bhatiri voltage uye bhatiri terminal.

Unogona kuenderera nekubatanidza iyo scanner uye kutora ese akachengetwa makodhi uye kuomesa furemu data. Ive neshuwa yekunyora pasi iyi ruzivo kuitira ramangwana rezita. Zvino bvisa macode ese akachengetedzwa uye bvunzo kutyaira mota. Uchishandisa iyo DVOM, tarisa iyo DPF yekumanikidza sensor. Tarisa bhuku rekugadzira rebasa kuti uwane mirayiridzo. Iyo sensor inofanirwa kutsiviwa kana ikasasangana nemagadzirirwo ekupikisa maratidziro.

DPF yekumanikidza sensor yekupa hoses inofanirwa kuongororwa kuti yakavhara sei uye / kana kutyora kana iyo sensor ichiongorora. Tsiva hoses kana zvichidikanwa (yakanyanya tembiricha silicone hoses inokurudzirwa).

Unogona kutanga kuyedza maseketi ehurongwa kana tambo dzemagetsi dzakanaka uye sensor yakanaka. Dzinga vese vanobatana vanodzora usati waedza kudzvanywa kuramba uye / kana kuenderera (neDVOM). Iyo yakavhurika kana ipfupi dunhu mudunhu rinofanirwa kugadziriswa kana kutsiviwa.

Zvimwe zvekuongorora manotsi:

• Gadzirisa kuburitsa kuneta usati waedza kuongorora iyi kodhi.
• Clogged sensor ports uye clogged sensor tubes zvakajairika
• DPF yekumanikidza sensor hoses iyo yakanyungudutswa kana kutemwa ingangoda kudzokororwa mushure mekutsiva

Tsiva / gadzirisa zvikamu izvi kugadzirisa kodhi P2454

1. Injini yekudzora module . Kwete nguva dzose zvikamu, asi ECM inogona kukanganisa. Izvi zvinogona kutungamira mukududzirwa zvisizvo kweiyo data chaiyo, zvichitungamira kune zvisirizvo sarudzo dzekuita izvo zvinokanganisa kutapurirana uye kuita kwese injini. Saka, tsiva iyo yakashata module uye igadzirise iko zvino!
2. Diesel Exhaust Fluid Pump . Iyo dhiziri inopedza mvura pombi inowanzowanikwa muvhavha yekufambisa. Inodhonza mvura kubva papombi pazasi pekutapurirana uye ichipa iyo kune iyo hydraulic system. Iyo zvakare inopa chikafu chinotonhorera uye torque converter. Saka, tsiva pombi yemvura isina kunaka izvozvi!

4. EGR valve Une matambudziko neinjini? Kana pane zvisizvo muEGR valve, ichavhiringidza chiyero chemhepo-mafuta mumotokari, izvo zvinozopedzisira zvakonzera matambudziko ekushanda kweinjini zvakadai sekuderedzwa kwesimba, kuderedza kushanda kwemafuta, uye matambudziko ane chokuita nekukurumidza. Chitsive nekukurumidza.
5. Exhaust system zvikamu . Yakaremara exhaust system zvikamu zvinogona kutungamira kune ruzha kupera kweinjini. Kudzikiswa kwakakura muhupfumi hwemafuta, simba, uye kukurumidza kunowanzoonekwa kutanga kana zvikamu zve exhaust system zvatadza. Nokudaro, zvakakosha kuvashandura. Saina muZvikamu Avatar izvozvi kuti utore emhando yepamusoro auto zvikamu.
6. Egemagetsi control unit - Iyo ECU inodzora inotonhorera system nekutarisa tembiricha yekushandisa yebhatiri, saka kana kusashanda kwakaonekwa, inofanira kutsiviwa. Naizvozvo, tenga nyowani ECU module uye zvikamu kubva kwatiri!
7. diagnostic tool Shandisa emhando yekuongorora maturusi kugadzirisa chero OBD kukanganisa kodhi.
