P0454 Evaporator Emission System Pressure Sensor Intermittent
Papa Kuhikuhi DTC OBD-II
ʻO ka hōʻailona intermittent o ka mīkini paʻi kaomi o ka ʻōnaehana kaohi no ka hemo ʻana o ka mahu wahie
He aha keʻano o kēia?
ʻO kēia Code Diagnostic Trouble Code (DTC) kahi code transmic generic, ʻo ia hoʻi e pili ana i nā kaʻa lako OBD-II (Dodge, Ram, Ford, GMC, Chevrolet, VW, Audi, Toyota, a pēlā aku.). ʻOiai he laulā i ke ʻano, ʻokoʻa paha nā kaʻina hana kūikawā i ka hilinaʻi ʻana i ka brand / model.
Ke hōʻike ʻia kāu kaʻa OBD-II i ke code P0454, ke ʻano o ka mana o ka powertrain (PCM)
No ka hei ʻana i nā māhu wahie ma mua o ka pakele ʻana i ke lewa, hoʻohana ka ʻōnaehana EVAP i kahi waihona vented (i kapa ʻia he canister) e mālama i nā mahu mahu a hiki i ka hana ʻana o ka ʻenekini ma lalo o nā kūlana kūpono e puhi pono iā lākou.
Hoʻokuʻu ʻia nā mahu mai ka pahu wahie ma o ka vaʻa palekana (ma ka piko o ka pahu wahie). ʻO ke kaomi i hana ʻia i ka wā e waiho ana o ka wahie e hana ma ke ʻano he propellant a hoʻoikaika i nā mahu e pakele ma o kahi pūnaewele o nā paipu hao a me nā paipu kāpili; i ka hopena hele i ka waihona pahu lanahu. ʻAʻole hiki i ka kini kēpau ke komo wale i nā mahu o ka wahie, akā paʻa pū lākou iā lākou no ka hoʻokuʻu i ka manawa kūpono.
Aia kahi ʻōnaehana EVAP maʻamau o ka pahu kalapona, kahi sensor pressure EVAP, kahi kiwikā purse / solenoid, a valve control / solenoid, a me kahi ʻōnaehana paʻakikī o nā paipu hao a me nā hoses rubber e holo ana mai ka pahu wahie i ka ʻenekini.
ʻO ka kiwikā purge / solenoid, ʻo ia ka hub o ka ʻōnaehana EVAP, kaohi uila ʻia e ka PCM. Hoʻohana ʻia ka kiwikā purge / solenoid i mea e hoʻoponopono ai i ka hakahaka ma ka puka komo i ka pahu wai EVAP i mea e huki ʻia ai nā mahu i loko o ka ʻenekini ke kūpono nā kūlana e puhi iā lākou ma ke ʻano he wahie ma kahi o ka hoʻohaumia ʻana i ka lewa.
Ke nānā ʻia nei ke kaomi EVAP e ka PCM me ka hoʻohana ʻana i ke kiʻina puʻupuʻu EVAP. Hiki i ka mīkini paʻi puʻupuʻu EVAP ke paʻakikī i ke komo ʻana no ka mea maʻa mau ia ma ka piko o ka pahu wahie a hoʻokomo ʻia i loko o ka pauma wahie / wahie e hoʻouna ai i kahi hale. Ināʻike ka PCM i ka manawa pinepine o ka hōʻailona puʻupuʻu EVAP, e mālama ʻia kahi pāʻālua P0454 a e hoʻomālamalama ʻia ka Lam Malama Hōʻailona (MIL).
Hoʻopili nā DTC emission pili pū me P0450, P0451, P0452, P0453, P0455, P0456, P0457, P0458, a me P0459.
Ka nui o nā code a me nā ʻōuli
Pākuʻi ʻia paha nā ʻōuli o kēia pāʻālua:
- I ka hapanui o nā hihia, ʻaʻole e ʻike ʻia nā ʻōuli me kahi pāʻālua P0454.
- Hoʻemi iki i ka pono wahie
- MIL Hoʻomālamalama (Kahi Hōʻike ʻālikelike Malfka)
kumu
Nā kumu kūpono no ka hoʻonohonoho ʻana i kēia code:
- Kaha mīkini uila EVAP hewa
- Pākuʻi ʻia ka pahu pahu pahu pahu wahie.
- Wehe a pōkole paha ke kaapuni i nā uwea a i ʻole nā mea hoʻopili o ka mīkini paʻi puʻupuʻu EVAP
- Pahu a haki paha nā nahu
Nā diagnostics a me nā kaʻina hana hoʻoponopono
Inā ʻike au i kahi hōʻailona kuhi P0454, ʻike wau e pono ana wau i kahi scanner diagnostic, kahi volt / ohmmeter uila, kahi kumu hilinaʻi o ka ʻike kaʻa e like me All Data DIY, a me kahi mīkini uahi paha.
ʻO ka nānā ʻana i nā paipu, nā laina, nā ʻili uila, a me nā mea hoʻohui o ka ʻōnaehana EVAP kahi wahi maikaʻi e hoʻomaka ai e ʻike. E noʻonoʻo pono i nā ʻāpana kokoke i nā kihi ʻoi a i ʻole nā mea ʻōnaehana hoʻopau wela. Mai poina e wehe i ka pāpale pahu wahie, e nānā i ke sila a hoʻopaʻa pono.
A laila makemake wau e hoʻohui i ka scanner i ke awa diagnostic kaʻa a kiʻi i nā code āpau i mālama ʻia a paʻa i ka ʻikepili paʻa manu. He manaʻo maikaʻi e kākau i kēia ʻike ma lalo no ka mea hiki ke lilo ia i mea maikaʻi loa, keu hoʻi inā lilo ia i code intermittent. Ma hope o kēlā, makemake wau e hoʻomaʻemaʻe i nā code a hoʻāʻo e hoʻokele i ke kaʻa a hiki i ke komo ʻana i ka mode mākaukau ʻo OBD-II a i ʻole ua holoi ʻia ke code. Koi pinepine nā code EVAP i mau holo kaʻa he nui (me kēlā me kēia holo ʻole) ma mua o ka hoʻonohonoho hou ʻana.
E nānā i ka hōʻailona mai ka mīkini paʻi puʻupuʻu EVAP e hoʻohana ana i ke kahawai diagnostics o ka scanner. ʻIke wau ua hoʻoponopono wau i ke ʻano (ma ka hoʻopaʻa ʻana a i ʻole ka hoʻololi ʻana i ka pāpale wahie) inā aia ke kaomi o ka ʻōnaehana i loko o nā kikoʻī i manaʻo ʻia e ka mea hana,
E nānā wau i ke kiʻina puʻupuʻu EVAP ma mua o ka hana ʻana i ka hoʻāhu uahi no ka mea he pāʻālua kaiapuni mīkiniʻimi pākīkē. Hiki i ka wahi o ka mīkini paʻi puʻupuʻu EVAP ke hoʻopilikia i ka hoʻāʻo ʻana no ka mea aia ma ka wēlau o ka pahu wahie. Ke komo ʻana i ka mea ʻike, e hāhai i nā kuhikuhi hoʻokolohua a ka mea hana a hoʻololi i ka sensor inā ʻaʻole ia i kikoʻī.
E hoʻokaʻawale i nā mea hoʻokele e pili ana a nānā i kēlā me kēia kaapuni me ka DVOM inā e hālāwai ka mīkini paʻi EVAP me nā kikoʻī o ka mea hana. Hoʻoponopono a hoʻololi paha i nā kaapuni hāmama a pōkole paha e like me ka pono a hōʻike hou i ka ʻōnaehana.
Nā memo diagnostical hou aʻe:
- ʻO ka haʻahaʻa a kiʻekiʻe paha o ka EVAP kaomi e hoʻomau ai i ka P0454 e hoʻomau.
- Hiki ke hoʻokumu ʻia kēia code e nā pilikia uila a mechanical paha.
Nā kūkākūkā DTC e pili ana
- Code Malibu P2010 0454Code no 2010 Malibu 454? Ma hea e hoʻomaka ai: me nā uea a i ʻole ma lalo o ka pāpale? ...
Pono i kōkua hou me kāu code p0454?
Inā makemake ʻoe i kōkua me DTC P0454, kau i kahi nīnau i nā manaʻo ma lalo o kēia ʻatikala.
OLELO HOOLAHA. Hāʻawi ʻia kēia ʻike no ka ʻike wale nō. ʻAʻole ia e manaʻo ʻia e hoʻohana ʻia ma ke ʻano he ʻōlelo hoʻomaikaʻi a ʻaʻole kuleana mākou no kekahi hana āu e hana ai i kekahi kaʻa. Pale ʻia ka ʻike āpau ma kēia pūnaewele e nā kuleana kope.
