I-P2454 Udizili Particulate Filter Pressure Sensor Signal Low

Ikhodi Yenkinga ye-OBD-II - P2454 - Ishidi Ledatha

I-P2454 - Isignali ephansi kumjikelezo wenzwa yokucindezela yesihlungi se-particle A

Isho ukuthini ikhodi yenkinga P2454?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza kuzo zonke izimoto kusukela ngo-1996 (Ford, Dodge, GMC, Chevrolet, Mercedes, VW, njll.). Yize kuvamile emvelweni, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli.

Ngithole ukuthi ngenkathi kugcinwa ikhodi engu-P2454, i-powertrain control module (PCM) ithole amandla kagesi aphansi asuka kusifunda se-DPF pressure sensor circuit esiqokelwe A. Izimoto ezinezinjini zikadizili kuphela okufanele zibe nale khodi.

Idizayinelwe ukususa amaphesenti ayisishiyagalolunye ezinhlayiya zekhabhoni (insizi) kusuka ekuqothulweni kukadizili, izinhlelo ze-DPF seziba yinto ejwayelekile ezimotweni zikadizili. Izinjini zikadizili (ikakhulukazi ekusheshiseni okuphezulu) zikhipha intuthu emnyama emnyama kusuka kumagesi abo okukhipha. Ingabhekwa njenge-soot. I-DPF imvamisa ifana nesiguquli esingaguquki noma esiguquguqukayo, esifakwe ezindlini zensimbi futhi sitholakala phezulu komguquli we-catalytic (kanye / noma nox isicupho). Ngokwakheka, izinhlayiya zomsizi ezivalekile zibhajwe entweni ye-DPF, kuyilapho izinhlayiya ezincane (namanye amakhemikhali e-exhaust) angadlula kuyo.

Amakhemikhali amaningana asetshenziswayo njengamanje asetshenziselwa ukubamba izinhlayiya ezinkulu zomsizi ezikhishwa kumagesi aqeda udizili. Lokhu kungafaka: imicu yamaphepha, imicu yensimbi, imicu ye-ceramic, imicu yodonga abicah, kanye nemicu yodonga lwe-cordierite. I-Cordierite esekwe ku-Ceramic iyinhlobo yefayibha ejwayelekile kakhulu esetshenziswa kuzihlungi ze-DPF. I-Cordierite inezici ezinhle kakhulu zokuhlunga futhi ayibizi ukukhiqiza. Kodwa-ke, i-cordierite yaziwa ukuthi inezinkinga ngokushisa ngokweqile emazingeni okushisa aphakeme, okuyenza ibe sengozini yokungasebenzi kahle ezimotweni ezihlome nge-passive particulate filter system.

Enhliziyweni yanoma iyiphi i-DPF kuyinto yokuhlunga. Izinhlayiya ezinkulu zomsizi zibhajwe phakathi kwezintambo njengoba kudlula amagesi okukhipha injini. Njengoba izinhlayiya zomsizi ezihlanganayo ziqongelela, ingcindezi yokukhipha inyuka. Ngemuva kokuthi ingcindezi yegesi yokukhipha ifinyelele ezingeni elihleliwe, into yokuhlunga kufanele ivuselelwe. Ukuvuselelwa kuvumela ukuthi amagesi okukhipha umoya aqhubeke nokudlula kwi-DPF futhi agcine izinga lengcindezi elifanele.

Izinhlelo ezisebenzayo ze-DPF zivuselelwa ngokuzenzakalela. Kulolu hlobo lohlelo, i-PCM ihlelelwe ukufaka amakhemikhali (kufaka phakathi kepha kungagcini kudizili nakukhipha uketshezi) ku-DPF ngezikhathi ezihleliwe. Lo mjovo olawulwa nge-elekthronikhi ubangela ukuba izinga lokushisa kwamagesi okukhipha umoya likhuphuke, okuvumela izinhlayiya zomsizi obhajwe ukuba zishe futhi zikhishwe njenge-nitrogen ne-oxygen ions.

Amasistimu we-Passive DPF ayafana (ngombono) kepha adinga okokufaka okuthile kusuka ku-opharetha. Lapho isiqalile, inqubo yokuvuselela ingathatha amahora ambalwa. Ezinye izimoto zidinga indawo yokulungisa efanelekayo yenqubo yokuvuselela. Amanye amamodeli aklanywe ngendlela yokuthi i-DPF kumele isuswe emotweni futhi ihlinzekwe ngomshini okhethekile oqeda inqubo nokususa izinhlayiya zomsizi.

Lapho izinhlayiya zomsizi sezisuswe ngokwanele, i-DPF ibhekwa njengokuvuselelwa kabusha. Ngemuva kokuvuselelwa, ingcindezi yokubuyisa emuva kufanele ibuyele ezingeni elamukelekayo.

Inzwa yengcindezi ye-DPF imvamisa ifakwa egumbini lenjini futhi kude ne-DPF. Ingcindezi yokubuyisa emuva ibhekwa inzwa (lapho ingena ku-DPF) isebenzisa amapayipi abicah (axhunywe kwi-DPF ne-DPF sensor sensor).

Ikhodi ye-P2454 izogcinwa uma i-PCM ithola isimo sengcindezi yokukhipha engaphansi kwemininingwane yomkhiqizi, noma okokufaka kagesi okuvela ku-DPF Inzwa yokucindezela engaphansi kwemikhawulo ehleliwe.

Izimpawu nobukhali

Izimo ezingadala ukuthi le khodi iqhubeke kufanele zithathwe njengeziphuthumayo ngoba zingadala ukulimala enjini yangaphakathi noma ohlelweni lukaphethiloli. Izimpawu zekhodi ye-P2454 zingafaka:

• Ukushisa kwenjini okwandisiwe
• Ngaphezulu kwamazinga okushisa ajwayelekile okuhambisa
• Ukunciphisa ukusebenza kwenjini
• Sekukonke ukusebenza kwenjini kungase kuqale ukwehla
• Kungase kuqale kuphume intuthu emnyama epayipini lokukhipha umoya wemoto.
• Izinga lokushisa lenjini lingase libe lidlulele

Izimbangela zephutha P2454

Izizathu ezingaba khona zokusetha le khodi:

• Khipha ukuvuza
• Amashubhu we-DPF sensor sensor / hoses avalekile
• Isifunda esivulekile noma esifushane ku-DPF sensor sensor A circuit
• Inzwa yengcindezi eyiphutha ye-DPF
• Ithangi le-diesel exhaust fluid lingaba mahhala
• Uketshezi Lokukhipha Udizili olungalungile
• Inzwa ye-DPF pressure Circuit ingase ivuleke noma inganele
• Ukungakwazi ukukhiqiza kabusha i-DPF
• Isistimu yokuvuselela i-DPF ingase yehluleke

Izinqubo zokuxilonga nokulungisa

Iphuzu elihle lokuqala ngaso sonke isikhathi ukuhlola ama-bulletins ezinsizakalo zobuchwepheshe (i-TSB) yemoto yakho ethile. Inkinga yakho ingaba inkinga eyaziwa ngesilungisi esikhishwe ngumkhiqizi futhi ingakongela isikhathi nemali ngenkathi uxazulula inkinga.

Kudingeka i-digital volt / ohmmeter, ibhukwana lesevisi yomkhiqizi, kanye neskena sokuxilonga ukuxilonga ikhodi ye-P2454.

Qala ukuxilongwa kwakho ngokuhlola ngokubonakalayo ama-harnesses nezixhumi ezifanele. Hlola eduze i-wiring ehanjiswa eduze kwezingxenye zokushisa okushisayo kanye / noma emaphethelweni ajwayelekile. Lesi sinyathelo sigcina ngokubheka ukuphuma kwe-generator, i-voltage yebhethri ne-terminal yebhethri.

Ungaqhubeka ngokuxhuma isithwebuli futhi ubuyise wonke amakhodi agciniwe futhi umise idatha yozimele. Qiniseka ukuthi ubhala phansi lolu lwazi ukuze ulusebenzise ngokuzayo. Manje sula wonke amakhodi agciniwe bese uhlola ukushayela imoto. Usebenzisa i-DVOM, hlola inzwa yengcindezi ye-DPF. Bheka ibhukwana lesevisi yomkhiqizi ukuthola imiyalo. Inzwa kufanele ishintshwe uma ingahlangabezani nezincazelo zomkhiqizi.

Amapayipi okuhlinzekwa kwezinzwa zokucindezelwa kwe-DPF kufanele ahlolwe ukuvalwa kanye / noma ukwephuka uma inzwa ihlola. Faka amanye amapayipi uma kunesidingo (kunconywa amapayipi okushisa abicah aphezulu).

Ungaqala ukuhlola amasekethe wesistimu uma izintambo zikagesi zilungile futhi inzwa ilungile. Nqamula zonke izilawuli ezihambisanayo ngaphambi kokuhlola ukumelana kwesifunda kanye / noma ukuqhubeka (nge-DVOM). Isifunda esivulekile noma esifushane esifundeni kufanele silungiswe noma sishintshwe.

Amanothi wokuxilonga angeziwe:

• Lungisa ukuvuza kokukhipha ngaphambi kokuzama ukuthola le khodi.
• Izimbobo zezinzwa ezivalekile namashubhu enzwa avalekile kuvamile
• Amapayipi we-DPF sensor sensor ancibilikisiwe noma asikiwe angadinga ukuphinde ahanjiswe ngemuva kokufakwa esikhundleni

Miselela/lungisa lezi zingxenye ukuze ulungise ikhodi P2454

1. Imojula yokulawula injini . Akuzona njalo izingxenye, kodwa i-ECM ingaba nephutha. Lokhu kungaholela ekuhunyushweni okuyiphutha kwedatha okuyiyonayona, okuholela ezinqumweni zokusebenza ezingalungile ezizothinta ukudluliswa kanye nokusebenza kwenjini kukonke.

4. I-valve ye-EGR - Ingabe unezinkinga ngenjini? Uma kukhona ukushoda kwe-valve ye-EGR, izophazamisa isilinganiso sikaphethiloli womoya emotweni, okuzogcina kubangele izinkinga zokusebenza kwenjini njengokuncishiswa kwamandla, ukuncipha kokusebenza kahle kukaphethiloli, nezinkinga ezihlobene nokusheshisa. Yishintshe ngokushesha.
5. Izingxenye zesistimu ye-exhaust . Izingxenye zesistimu ye-exhaust engalungile zingaholela ekukhishweni kwenjini enomsindo. Ukuncipha okukhulu komnotho kaphethiloli, amandla kanye nokusheshisa kungenzeka kubonakale kuqala uma izingxenye ze-exhaust system zihluleka. Ngakho-ke, kubalulekile ukuwashintsha. Ngena ngemvume ku-Parts Avatar manje ukuze uthole izingxenye ezizenzakalelayo zekhwalithi ephezulu kakhulu.
6. Iyunithi yokulawula ngogesi - I-ECU ilawula uhlelo lokupholisa ngokuqapha izinga lokushisa lokusebenza kwebhethri, ngakho-ke uma kutholakala ukungasebenzi kahle, kufanele kushintshwe. Ngakho-ke, thenga amamojula amasha we-ECU nezingxenye ezivela kithi!
7. ithuluzi lokuxilonga Sebenzisa amathuluzi okuxilonga ekhwalithi ukuze uxazulule noma iyiphi ikhodi yephutha ye-OBD.
