P0454 Evaporator Emission System Pressure Sensor Intermittent

P0454 Evaporator Emission System Pressure Sensor Intermittent

Mapepala a OBD-II DTC

Chizindikiro chosasunthika cha mphamvu yamagetsi yothandizira kuti muchotse mafuta

Kodi izi zikutanthauzanji?

Izi Diagnostic Trouble Code (DTC) ndi njira yofalitsira, zomwe zikutanthauza kuti imagwira ntchito pamagalimoto okhala ndi OBD-II (Dodge, Ram, Ford, GMC, Chevrolet, VW, Audi, Toyota, etc.). Ngakhale ndizachilengedwe, njira zowongolera zimatha kusiyanasiyana kutengera mtundu / mtundu.

Galimoto yanu yokhala ndi OBD-II ikawonetsa nambala ya P0454, zikutanthauza kuti gawo loyendetsa mphamvu yamagetsi (PCM) lapeza chizindikiritso chosazungulira kuchokera ku EVAP pressure sensor dera.

Pofuna kutulutsa nthunzi yamafuta asanathawire mumlengalenga, makina a EVAP amagwiritsa ntchito mosungira madzi (omwe amadziwika kuti canister) kuti asungire nthunzi wamafuta ochulukirapo mpaka injini ikamagwira ntchito moyenera kuti iwotche bwino.

Mitambo yochokera mu thanki yamafuta imatulutsidwa kudzera pa valavu yachitetezo (pamwamba pa thankiyo yamafuta). Kupsyinjika komwe kumachitika posungira mafuta kumachita ngati kothamangitsa ndipo kumapangitsa kuti nthunzi zizithawa kudzera pamipanda yachitsulo ndi ma payipi a labala; pamapeto pake pitani ku kabokosi kosungira makala. Canister imangotenga nthunzi zamafuta zokha, komanso imagwira kuti izitulutsidwa munthawi yoyenera.

Makina amtundu wa EVAP amakhala ndi thanki ya kaboni, sensa yamagetsi ya EVAP, valavu yochotsa / solenoid, valavu yothana ndi utsi, ndi makina ovuta azitsulo ndi ma payipi a labala omwe amayenda kuchokera mu thanki yamafuta kupita kumalo opangira injini.

Chotsukira cha valve / solenoid, chomwe chimayendetsa dongosolo la EVAP, chimayendetsedwa pakompyuta ndi PCM. Valavu yoyeretsa / solenoid imagwiritsidwa ntchito kuwongolera zingalowe polowera ku EVAP canister kuti mafuta azitulutsa mu injini pomwe zinthu zili bwino kuwotcha ngati mafuta m'malo moipitsa mpweya.

Kupanikizika kwa EVAP kumayang'aniridwa ndi PCM pogwiritsa ntchito kachipangizo ka EVAP. Zida zamagetsi za EVAP zitha kukhala zovuta kuzipeza chifukwa nthawi zambiri zimakhala pamwamba pa thanki yamafuta ndipo zimamangidwa munyumba yamafuta yamafuta. PCM ikazindikira kuti chizindikiritso cha EVAP ndichapakatikati, nambala ya P0454 idzasungidwa ndipo Nyali Yosagwira Ntchito (MIL) itha kuwunikira.

Ma DTC ophatikizidwa ndi P0450, P0451, P0452, P0453, P0455, P0456, P0457, P0458, ndi P0459.

Kuuma kwa code ndi zizindikilo

Zizindikiro za code iyi zitha kuphatikiza:

• Nthawi zambiri, zizindikiro zokhala ndi nambala ya P0454 sizimawonekera.
• Kuchepetsa pang'ono mafuta
• Kuunikira kwa MIL (Nyali Yazizindikiro Zosagwira)

zifukwa

Zifukwa zomwe zingakhazikitsire nambala iyi:

• Chojambulira cholakwika cha EVAP
• Valavu yothandizira mafuta thanki yadzala.
• Tsegulani kapena zazifupi mu waya kapena zolumikizira zamagetsi a EVAP
• Mng'alu Wosweka Kapena Wosweka

Njira zowunikira ndikukonzanso

Ndikapeza kachilombo ka P0454, ndikudziwa ndikufunika chojambulira, digito volt / ohmmeter, gwero lodalirika lazidziwitso zamagalimoto monga All Data DIY, ndipo mwina ngakhale makina osuta.

Kuyang'ana kowonekera kwa ma hose, mizere, zida zamagetsi, ndi zolumikizira za dongosolo la EVAP ndi malo abwino oyambira kuzindikira. Samalani kwambiri magawo omwe ali pafupi ndi nsonga zakuthwa kapena zigawo zotentha zotulutsa mpweya. Musaiwale kuchotsa kapu ya tanki yamafuta, yang'anani chisindikizo ndikuchimanga bwino.

Kenako ndimakonda kulumikiza sikani ku doko loyang'anira magalimoto ndikutenga ma code onse osungidwa ndikuwumitsa chimango. Ndibwino kulemba izi chifukwa zitha kukhala zothandiza kwambiri, makamaka ngati zingapezeke kuti ndizapakatikati. Pambuyo pake, ndimakonda kuchotsa ma code ndikuyesa kuyendetsa galimotoyo mpaka ilowa mu OBD-II modzidzimutsa kapena codeyo itakonzedwa. Zizindikiro za EVAP zimafunikira mayendedwe angapo oyendetsa (ndikulephera kulikonse) musanakhazikitsenso.

Onetsetsani chizindikirocho kuchokera ku kachipangizo kamene kamagwiritsa ntchito EVAP pogwiritsa ntchito njira yojambulira. Ndikudziwa kuti ndawongolera vutoli (polimbitsa kapena kusintha mafuta) ngati kupanikizika kwa makina kuli mogwirizana ndi zomwe wopanga akufuna,

Ndimayang'ana kachipangizo kameneka ka EVAP ndisanayese utsi chifukwa ndi kachidindo kamene kamakhala ndi kachipangizo kozungulira. Komwe kuli kachipangizo kamagetsi ka EVAP kumatha kupangitsa mayesedwe popeza nthawi zambiri amakhala pamwamba pa thanki yamafuta. Mukamaliza sensa, tsatirani malangizo oyeserera a wopanga ndikusintha sensa ngati sichinafotokozeredwe.

Chotsani maulamuliro onse omwe ali nawo ndikuyang'ana ma circuits aliwonse ndi DVOM ngati EVAP pressure sensor ikwaniritsa zomwe wopanga amapanga. Konzani kapena sinthani ma circuits otseguka kapena afupikitsidwe ngati kuli kofunikira ndikuyesanso makinawo.

Zowonjezera zowonjezera:

• Kutsika kapena kuthamanga kwa EVAP kumatha kuyambitsa P0454 kupitilira.
• Nambala iyi imatha kuyambitsidwa ndi mavuto amagetsi kapena makina.

Zokambirana zokhudzana ndi DTC

• Code Malibu P2010 0454Code ya 2010 Malibu 454? Kuti muyambire pati: ndi waya kapena pansi pa hood? ... 

Mukufuna thandizo lina ndi nambala yanu ya p0454?

Ngati mukufunabe thandizo ndi DTC P0454, 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.
