P046C Utsi Mpweya Recirculation SENSOR osiyanasiyana

Khodi Yovuta ya OBD-II - P046C - Tsamba la Data

P046C - Sensor Exhaust Gas Recirculation Sensor "A" Circuit Range/Performance

Kodi DTC P046C imatanthauza chiyani?

Iyi ndi generic Transmission Diagnostic Trouble Code (DTC), zomwe zikutanthauza kuti imagwira ntchito pakupanga / mitundu yonse kuyambira 1996 kupita mtsogolo. Komabe, njira zina zothetsera mavuto zimatha kusiyanasiyana ndi galimoto.

Khodi yavuto ya on-board (OBD) P046C ndi vuto lanthawi zonse lokhudzana ndi mitundu ingapo kapena vuto lomwe lachitika mu Exhaust Gas Recirculation (EGR) valve circuit "A".

Mpweya wotsekemera wa mpweya umagwiritsidwa ntchito popereka mpweya wochuluka wambiri ku zowonjezera. Cholinga ndikuteteza kutentha kwa mutu wamutu pamunsi pa 2500 Fahrenheit. Oxygen nitrate (Nox) amapangidwa kutentha kukakwera pamwamba pa 2500 degrees Fahrenheit. Nox ndi amene amachititsa utsi komanso kuipitsa mpweya.

Makompyuta olamulira, mwina powertrain control module (PCM), kapena module yamagetsi yamagetsi (ECM) azindikira ma voliyumu otsika modabwitsa, okwera kapena osakhalapo. Onaninso buku lokonzekera la wopanga kuti mudziwe sensa yotani "A" yomwe imayikidwa mgalimoto yanu.

Momwe mpweya wamafuta wamafuta umagwirira ntchito

DTC P046C imatanthawuza vuto lomwelo pamagalimoto onse, komabe pali mitundu yambiri ya EGR, masensa ndi njira zoyeserera. Kufanana kokha ndikuti onse amatulutsa mpweya wotulutsa utsi muzambiri zomwe umadyetsa kuti uziziritsa mutu wamphamvu.

Kutsanulira utsi mu injini nthawi yolakwika kumachepetsa mphamvu yamahatchi ndikupangitsa kuti izichita ulesi kapena khola. Ndili ndi malingaliro, mapulogalamu apakompyuta amangotsegula EGR pa injini rpm pamwamba pa 2000 ndikutseka katundu.

Zizindikiro

Mofanana ndi zizindikiro zina zolakwika, code iyi imayambitsa kuwala kwa Check Engine ndikuyika kachidindo mu galimoto. Zizindikiro zina zimadalira malo a pini ya EGR pa nthawi ya vutolo.

Zizindikiro zimadalira pomwe singano yotulutsa mpweya ikamatuluka panthawi yolakwayo.

• Khodi yachiwiri yokhudzana ndi kulephera kwa sensor ya EGR ikhoza kukhazikitsidwa. Khodi yolakwika P044C imatanthawuza kutsika kwamagetsi a sensor, pomwe code yolakwika P044D imatanthawuza kukwera kwamagetsi.
• Pini ya EGR imakhala yotseguka pang'ono, zomwe zimapangitsa kuti galimotoyo isagwire ntchito bwino kapena kuyimitsidwa
• Kuphulika kwa phokoso pamene galimoto ikulemedwa kapena ikuthamanga kwambiri
• Posachedwa ma injini yamagetsi adzafika ndipo nambala ya OBD P046C iyikidwa. Mwasankha, nambala yachiwiri ikhoza kukhazikitsidwa yokhudzana ndi kulephera kwa sensa ya EGR. P044C amatanthauza mphamvu yamagetsi yotsika kwambiri ndipo P044D imatanthawuza za magetsi.
• Pini ya EGR ikatseguka pang'ono, galimotoyi siyingokhala kapena kuyima.
• Kulira kwa kugogoda kumamveka pakatundu kapena pa rpm yayikulu
• Palibe zizindikiro

Zomwe Zingatheke ndi Code P046C

• Cholakwika utsi recirculation kachipangizo "A"
• Chingwe cholumikizira cholakwika ku sensa
• Pini ya EGR imakanika potsekedwa ndipo kukhazikika kwa kaboni kumatchinga kuti isatsegulidwe
• Kusowa kwa zingalowe m'malo opangira utsi wamagetsi.
• Zolakwika utsi recirculation solenoid
• Utsi mpweya recirculation malo kachipangizo zosalongosoka
• Zowonongeka zamafuta obwezeretsa mpweya masiyanidwe okakamiza pamagetsi.

Momwe mungayang'anire DTC P046C

Mukazindikira kachidindo kameneka, dziwani kuti mawaya amasiyana ndi wopanga wina, ndipo makompyuta sangayankhe bwino ngati waya wolakwika akufufuzidwa. Kulumikizana ndi waya wa crimp kumapangitsa kuti magetsi ochulukirapo adutse kudzera pa cholumikizira cha sensor ya pakompyuta, zomwe zingayambitse kompyuta kuyaka.

Komanso, ngati cholumikizira cholakwika chatsekedwa, kompyuta ikhoza kutaya mapulogalamu ake onse, zomwe zimapangitsa kuti zikhale zosatheka kuyambitsa galimoto. Pankhaniyi, galimoto iyenera kutengedwa kwa wogulitsa kuti kompyutayo ikonzedwenso.

Kuti adziwe matenda, akatswiri nthawi zambiri amayang'ana cholumikizira cha sensa ya EGR ndikuyang'ana zizindikiro za dzimbiri, zopindika kapena zotalikirapo, komanso zolumikizira zotayirira. Kenako amatsuka dzimbiri ndikukhazikitsanso cholumikizira.

Kenako amapitilira kuchotsa cholumikizira chamagetsi ndi EGR. Kenako yang'anani kuchuluka kwa coking ndi exhaust system EGR. Amachotsa ma depositi aliwonse a kaboni kuti pini isunthike mmwamba ndi pansi bwino.

Kenaka amayang'ana mzere wa vacuum kuchokera ku EGR kupita ku solenoid, kuyang'ana zolakwika ndi zowonongeka ndikusintha ngati kuwonongeka kwapezeka.

Amayang'ana cholumikizira chamagetsi cha solenoid ndikuyang'ana zizindikiro za dzimbiri ndi kuwonongeka.

Kwa magalimoto a Ford, akatswiri amayenera kutsatira ma hoses awiri ochotsamo kuchokera ku EGR kupita ku sensa ya DPFE (EGR Differential Pressure Feedback) kumbuyo kwa manifold.

Kenako amawunika mipope iwiri yopondereza ndikuyang'ana zizindikiro za dzimbiri. Mipaipi imeneyi nthawi zambiri imatseka mpweya wotulutsa mpweya. Choncho akatswiri adzagwiritsa ntchito screwdriver yaing'ono ya m'thumba kapena chida chofananira kuti achotse dzimbiri kuchokera pahose ndipo sensa idzayambiranso kugwira ntchito.

Njira zokonzera

Ma valve onse a EGR ali ndi chinthu chimodzi chofanana - amabwezeretsanso mpweya wotulutsa mpweya kuchokera ku utsi kupita kumalo ochulukirapo. Kuonjezera apo, amasiyana ndi njira zoyendetsera kutsegulidwa kwa singano ndikudziwitsa malo ake.

Njira zotsatirazi ndizomwe zimachitika chifukwa cha zovuta zambiri za EGR. Ngati chitsulo kapena cholumikizira chalakwika, buku lothandizira liyenera kudziwa njira zoyenera zodziwira ndikuzindikira mawaya.

Kumbukirani kuti zingwe zimasiyanasiyana kuchokera pakupanga mpaka makina, ndipo makompyuta samayankha bwino ngati waya wolakwika wafufuzidwa. Ngati mungayang'ane waya wolakwika ndikutumiza ma voliyumu ochulukirapo pamakina olowera pakompyuta, kompyutayo iyamba kuwotcha.

Nthawi yomweyo, cholumikizira cholakwika chikadulidwa, kompyuta imatha kutaya mapulogalamu, zomwe zimapangitsa kuti zikhale zovuta kuyambitsa injini mpaka wogulitsa atayambiranso kompyuta.

• P046C imawonetsa vuto pa dera B, chifukwa chake yang'anani cholumikizira cha EGR cha dzimbiri, malo opindika kapena otulutsidwa, kapena kulumikizana kotayirira. Chotsani dzimbiri ndikuyikanso cholumikizacho.
• Chotsani cholumikizira magetsi ndikuchotsa utsi wamagetsi. Chongani utsi recirculation polowera ndi kubwereketsa kwa coke. Ngati ndi kotheka, chotsani coke kuti singano isunthe bwino ndikukwera.
• Chongani chopukutira kuchokera ku utsi wamafuta oyendetsera mpweya kupita ku solenoid ndikusintha ngati zolakwika zilizonse zapezeka.
• Chongani cholumikizira chamagetsi chamagetsi ngati dzimbiri kapena dzimbiri.
• Ngati galimotoyo ndi Ford, tsatirani ma payipi awiriwo kuchokera pamagetsi otulutsa mpweya kupita ku sensa yamagetsi yotulutsa mpweya (DPFE) kumbuyo kwake.
• Onetsetsani ma payipi awiri amadzimadzi. Zomwe zachitika zikuwonetsa kuti ma payipiwa amathira kaboni m'mipope yotulutsa. Gwiritsani ntchito chowotchera thumba laling'ono kapena chofanana kuti muchotse dzimbiri zilizonse m'makina ndipo sensa iyambiranso.

Ngati mayeso ofala kwambiri sathetsa vutoli, buku lautumiki likufunika kuti mupitirize kuyang'ana mabwalo amagetsi. Njira yabwino yothetsera vutoli ndikutenga galimoto kupita kumalo osungirako ntchito ndi zipangizo zoyenera zowunikira. Amatha kuzindikira mwachangu ndikukonza vuto lamtunduwu.

Mukufuna thandizo lina ndi code p046C?

Ngati mukufunabe thandizo ndi DTC P046C, 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.
