P2454 Dizilo Particulate Filter Pressure Sensor Low Signal

Khodi Yovuta ya OBD-II - P2454 - Kufotokozera Zaukadaulo

P2454 - Sefa ya Dizilo ya Particulate A Pressure Sensor Circuit Low

Kodi vuto la P2454 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.

Ndinawona kuti posunga nambala ya P2454, gawo loyendetsa mphamvu yamagetsi (PCM) lapeza mphamvu yamagetsi yotsika kuchokera ku DPF pressure sensor dera yosankhidwa A. Magalimoto okhaokha okhala ndi injini za dizilo ndiwo ayenera kukhala ndi code iyi.

Zapangidwe kuti zichotse magawo makumi asanu ndi anayi mphambu makumi anayi a mpweya (mpweya) wa dizilo, makina a DPF akuyamba kukhala chizolowezi mgalimoto za dizilo. Ma injini a dizilo (makamaka akathamanga kwambiri) amatulutsa utsi wakuda wakuda kuchokera mumipweya yawo yotulutsa utsi. Itha kukhala m'gulu la mwaye. DPF nthawi zambiri imafanana ndi chosinthira chosakanikirana kapena chothandizira, chomangidwa mchikuta chachitsulo chomwe chimakhala kumtunda kwa chosinthira chothandizira (ndi / kapena NOx msampha). Mwa kapangidwe kake, ma coarse soot atsekedwa mu DPF element, pomwe tinthu tating'onoting'ono (ndi zinthu zina zotulutsa utsi) zimatha kudutsa.

Mitundu ingapo yama elemental pano imagwiritsidwa ntchito kutchera tinthu tating'onoting'ono totulutsa mpweya tomwe timatulutsa mu dizilo. Izi zingaphatikizepo: ulusi wamapepala, ulusi wachitsulo, ulusi wa ceramic, ulusi wamakona a silicone, ndi ulusi wa wall wa cordierite. Ceramic-based cordierite ndiye mtundu wofala kwambiri wa fiber womwe umagwiritsidwa ntchito pazosefera za DPF. Cordierite ili ndi mawonekedwe abwino osefera ndipo ndiotsika mtengo kupanga. Komabe, cordierite imadziwika kuti ili ndi vuto la kutenthedwa kwambiri pamatenthedwe, kupangitsa kuti izikhala pachiwopsezo cha kusokonekera kwa magalimoto omwe ali ndi zida zosefera zopanda kanthu.

Pamtima pa DPF iliyonse ndizosefera. Tinthu tating'onoting'ono totsekereza tatsekedwa pakati pa ulusiwo pomwe mpweya wamafuta umadutsa. Ma coarse soot particles amadziunjikira, kuthamanga kwa utsi kumawonjezeka. Mpweya wotulutsa utsi ukafika pamlingo woyenera, fyuluta iyenera kukonzedwanso. Kukonzanso kumapangitsa kuti mpweya wotulutsa mpweya upitirire kudutsa mu DPF ndikukhala ndi mpweya wabwino.

Machitidwe ogwiritsira ntchito DPF amasintha mwadzidzidzi. Mumtundu wamtunduwu, PCM idakonzedwa kuti ilowetse mankhwala (kuphatikiza koma osakwanira dizilo ndi kutulutsa madzi) mu DPF pakadutsa nthawi. Jekeseni woyendetsedwa pamagetsiwu umapangitsa kuti kutentha kwa mpweya kutuluke, kulola kuti tinthu tating'onoting'onoting'onoting'onoting'onoting'onoting'ono tokaka tukawotchera ngati ma ayitrogeni ndi ma oxygen.

Machitidwe a DPF osakhazikika ndi ofanana (mwamalingaliro) koma amafuna kuti athandizire ena. Mukayamba, njira yobwezeretsanso imatha kutenga maola angapo. Magalimoto ena amafunika malo ogulitsira oyenera kuti athe kukonzanso. Mitundu ina idapangidwa mwanjira yoti DPF iyenera kuchotsedwa mgalimoto ndikuthandizidwa ndi makina apadera omwe amaliza ntchitoyi ndikuchotsa ma tinthu tambiri.

Ma soot atachotsedwa mokwanira, DPF imadziwika kuti imasinthidwanso. Pambuyo pobadwanso mwatsopano, kuthamanga kwakumbuyo kwakumbuyo kuyenera kubwerera pamlingo wovomerezeka.

DPF sensor sensor nthawi zambiri imayikidwa mu chipinda cha injini komanso kutali ndi DPF. Kutulutsa kwakubwezeretsanso kumayang'aniridwa ndi sensa (ikamalowa mu DPF) pogwiritsa ntchito mapaipi a silicone (olumikizidwa ndi DPF ndi DPF pressure sensor).

Khodi ya P2454 idzasungidwa ngati PCM itazindikira vuto lakukhala lomwe lili pansi pamalingaliro a opanga, kapena kulowetsa kwamagetsi kuchokera ku DPF A sensor sensor yomwe ili pansi pamalire.

Zizindikiro ndi kuuma kwake

Zinthu zomwe zingayambitse kachidindo kameneka ziyenera kuganiziridwa mwachangu chifukwa zitha kuwononga injini yamkati kapena mafuta. Zizindikiro za chikhombo cha P2454 zitha kuphatikizira izi:

• Kuchuluka kwa kutentha kwa injini
• Pamwambapa kutentha kwachizolowezi
• Kuchepetsa ntchito ya injini
• Kugwira ntchito konse kwa injini kungayambe kuchepa
• Utsi wambiri wakuda ungayambe kutuluka m'paipi ya galimoto.
• Kutentha kwa injini kungakhale kochulukirapo

Zifukwa za P2454 kodi

Zifukwa zomwe zingakhazikitsire nambala iyi:

• Utsi kutayikira
• Machubu otsekemera a DPF atsekedwa
• Dera lotseguka kapena lalifupi mu sensa yamagetsi ya DPF
• Wopunduka DPF kuthamanga sensor
• Tanki yotulutsa dizilo imatha kukhala yaulere
• Chinyezi Cholakwika cha Dizilo
• DPF pressure sensor Sensor Circuit ikhoza kukhala yotseguka kapena yosakwanira
• Kulephera kupanganso DPF
• DPF regeneration system ikhoza kulephera

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.

Volt / ohmmeter ya digito, buku lothandizira opanga, ndi makina osakira amafunikira kuti adziwe nambala ya P2454.

Yambitsani kuzindikira kwanu poyang'ana mwanzeru ma harness ndi zolumikizira zoyenera. Yang'anitsaninso zingwe zomwe zimayendetsedwa pafupi ndi zida zotentha komanso / kapena m'mbali. Gawo ili limathera pakuwunika komwe kutulutsa kwa jenereta, ma batri amagetsi ndi ma batire akutha.

Mutha kupitilira polumikiza sikani ndikupeza ma code onse osungidwa ndikuimitsa chimango. Onetsetsani kuti mwalemba izi kuti mudzazigwiritse ntchito mtsogolo. Tsopano chotsani manambala onse osungidwa ndikuyesa kuyendetsa galimotoyo. Pogwiritsa ntchito DVOM, yang'anani kachipangizo kamene kali ndi DPF. Onaninso buku lazopanga kuti mupeze malangizo. Chojambuliracho chiyenera kusinthidwa ngati sichikugwirizana ndi malingaliro a wopanga.

Makina otulutsa ma sensor a DPF amayenera kufufuzidwa ngati atseka ndi / kapena kusweka ngati sensa ifufuza. Sinthanitsani ma payipi ngati kuli kotheka (mapiritsi otentha otsekemera amalimbikitsidwa).

Mutha kuyamba kuyesa mabwalo amachitidwe ngati mizere yamagetsi ndiyabwino ndipo sensa ndiyabwino. Chotsani owongolera onse omwe akuyanjanitsidwa musanayese kukana kwa dera komanso / kapena kupitiriza (ndi DVOM). Dera lotseguka kapena lalifupi m'chigawochi liyenera kukonzedwa kapena kusinthidwa.

Zowonjezera zowonjezera:

• Konzani zotulutsa zotulutsa musanayese kudziwa nambala iyi.
• Ma doko otsekeka a sensor ndi machubu otsekeka a sensor ndiofala
• Makina otsekemera a DPF omwe amasungunuka kapena kudulidwa angafunike kuwabwezeretsanso akadzasinthidwa

Bwezerani / konzani magawowa kuti mukonze khodi P2454

1. Module yowongolera injini . Osati zigawo zonse, koma ECM ikhoza kukhala yolakwika. Izi zingayambitse kutanthauzira molakwika kwa deta yolondola, zomwe zimapangitsa kuti pakhale zisankho zolakwika zomwe zingakhudze kufalitsa ndi ntchito yonse ya injini. Chifukwa chake, sinthani gawo lolakwika ndikulikonzanso tsopano!
2. Dizilo Exhaust Fluid Pump . Pampu yotulutsa dizilo nthawi zambiri imakhala pachivundikiro chotumizira. Imakoka madzimadzi kuchokera ku mpope pansi pa kufalikira ndikupereka ku hydraulic system. Imadyetsanso chosinthira chozizira komanso torque. Chifukwa chake, sinthani pampu yamadzi yolakwika tsopano!
3. Powertrain control module . Powertrain control module ingakhalenso yolakwika nthawi zina ndipo imafunika kufufuza mozama za zolakwika za dongosolo ndi mapulogalamu. Chifukwa chake, yang'anani ndikusintha ngati pakufunika.
4. EGR valve Kodi muli ndi mavuto ndi injini? Ngati pali zofooka zilizonse mu valavu ya EGR, zidzasokoneza chiŵerengero cha mpweya wa mpweya m'galimoto, zomwe pamapeto pake zidzadzetsa mavuto a injini monga kuchepa kwa mphamvu, kuchepa kwa mafuta, ndi mavuto okhudzana ndi kuthamanga. M'malo mwake posachedwapa.
5. Zigawo za dongosolo la utsi . Ziwalo zamakina olakwika zimatha kudzetsa phokoso la injini. Kuchepetsa kwakukulu kwa mafuta, mphamvu, ndi mathamangitsidwe amatha kuwonekera poyamba pamene mbali zina zautsi zalephera. Choncho, ndikofunikira kusintha. Lowani ku Parts Avatar tsopano kuti mupeze zida zapamwamba kwambiri zamagalimoto.
6. Choyang'anira pakompyuta - ECU imayang'anira dongosolo loziziritsa poyang'anira kutentha kwa batire, kotero ngati kuwoneka kolakwika, iyenera kusinthidwa. Chifukwa chake, gulani ma module atsopano a ECU ndi zigawo zake!
7. Chida chodziwira matenda Gwiritsani ntchito zida zowunikira kuti muthetse vuto lililonse la OBD.
