P0451 – OBD-II Pilikia Code wehewehe ʻenehana

Evaporative Emission Control Pressure Sensor Range/Hana

He aha ke ʻano o ke code hewa P0451?

Code P0451 - "Evaporative Emission System Pressure Sensor / Hoʻololi"

Hoʻomaka ʻia ke code P0451 i ka wā e ʻike ai ke kaʻa kaʻa mana mana mana (PCM) i kahi hōʻailona uila pololei ʻole a paʻa ʻole paha mai ka ʻōnaehana evaporative emission control pressure sensor.

Hoʻolālā ʻia ka ʻōnaehana hoʻoheheʻe evaporative (EVAP) e hopu a mālama i nā mahu wahie e pale aku iā lākou mai ke komo ʻana i ka lewa. Hōʻike ka Code P0451 i nā pilikia me ka mea ʻike kaomi i kēia ʻōnaehana.

Nā kumu kumu:

1. ʻAʻohe ʻikena puʻe EVAP.
2. Uea pōʻino a i ʻole mea hoʻohui uila e pili ana me ka ʻike kaomi.
3. ʻO nā pilikia me ka ʻōnaehana EVAP, e like me ka leak a i ʻole nā ​​​​paʻa.
4. Hana hewa ʻole ka PCM a i ʻole nā ​​pilikia uila ʻē aʻe.

Manaʻo ʻia ʻoe e kelepona i kahi mechanic kūpono a i ʻole ke kikowaena lawelawe e hoʻoholo pololei a hoʻoponopono i ke kumu.

Nā kumu kumu

Hiki ke hoʻonohonoho ʻia ke code P0451 no kēia mau kumu:

• ʻAʻohe ʻikena puʻe EVAP.
• ʻO ka pāpale wahie wehe a nalowale paha.
• Hoʻopaʻa ʻia ka pahu hoʻomaha kaomi i loko o ka pahu wahie.
• Ua pōʻino, luku a puhi ʻia paha nā paipu EVAP/laina.
• ʻO ka pahu lanahu naha a nahā paha.

ʻO ka mea maʻamau o kēia mau kumu, ʻo ia ka pahu wahie hewa, kahi pahu wahie hoʻoili hewa ʻole, kahi mea ʻike paʻi hāmama a pōkole paha a kaapuni paha i ka mīkini pahu pahu wahie.

He aha nā hōʻailona o kahi code hewa? P0451?

He liʻiliʻi paha nā hōʻailona o kahi code P0451 a loaʻa kēia mau mea:

• ʻO ka hapa nui o nā hihia me ka code P0451 ʻaʻole hōʻike i nā hōʻailona.
• He emi iki paha ka hoʻokele wahie.
• E hele mai ana ka Malfunction Indicator Light (MIL) ma ka papa hana.

Inā ua hoʻokumu kāu kaʻa i kahi code P0451, a laila ʻaʻole pono ʻoe e hana i nā hōʻailona koʻikoʻi. I ka hapanui o nā hihia, ʻo ka hōʻailona ʻike wale ʻia ʻo ke kukui ʻenekini nānā ma kāu dashboard e hele mai ana. Eia naʻe, ma waho aʻe o kēia hōʻailona, ​​ʻike paha ʻoe i kahi ʻala maikaʻi ʻole o ka ʻaila e puka mai ana mai ka ʻenekini, ma muli o ka hoʻokuʻu ʻia ʻana o nā mahu wahie.

Pehea e ʻike ai i kahi code hewa P0451?

Hiki ke paʻakikī ka ʻike pololei ʻana i ke code P0451. ʻO ka hapa nui o nā mea nona nā kaʻa makemake e hāʻawi i kēia hana i ka poʻe loea a waiho i kā lākou kaʻa no ka diagnostics.

Hoʻomaka maʻamau ke kaʻina diagnostic me kahi technician e heluhelu ana i nā code i mālama ʻia i loko o ka PCM o ka kaʻa me ka hoʻohana ʻana i kahi scanner OBD-II. Hoʻopili ʻia kēia mau code a hoʻomaka ka technician e nānā i kēlā me kēia ma ke ʻano o ka mālama ʻana i ka PCM. ʻO ka manawa pinepine, ma hope o ke code P0451, hiki ke hoʻomaka a mālama ʻia nā code OBD-II ʻē aʻe.

Ma hope o ka pau ʻana o ka scan, hana ke ʻenehana i ka nānā ʻana i ke kaʻa a me nā mea ʻike a me nā modules pili.

ʻO ka nānā ʻana a me ka ʻike ʻana i kahi code P0451 he kaʻina hana paʻakikī a manaʻo ʻia e waiho ʻia i kahi ʻoihana. Ma mua o ka ho'āʻo e hōʻoia iā ʻoe iho, ʻoi aku ka maikaʻi o ka huli ʻana i nā loea loea.

Ma hope o ka nānā ʻana a me ka ʻike ʻana i ke code, e hoʻomaka ke technician me kahi nānā ʻike, a ma ia manawa e nānā ʻo ia i nā uwea, nā mea hoʻohui, a me nā kaʻa no ka pōʻino. Ke hoʻoholo ʻia nā hewa i ʻike ʻia, e holoi ʻia ka code P0451 a e nānā hou ʻia ka ʻōnaehana.

Inā manaʻo ka ʻenehana ua pono nā mea a pau, e hoʻomau ʻo ia e nānā i ka pahu lanahu, ka pahu hoʻomaʻemaʻe, ka ʻumeke a me nā ʻili mahu, a me nā mea ʻē aʻe a pau e pili ana i ka ʻōnaehana hoʻoheheʻe evaporative. E nānā ʻia kēlā me kēia ʻāpana a, inā pono, e hoʻoponopono ʻia. E hoʻomaʻemaʻe ʻia nā code a nānā hou ʻia ka mīkini a hiki i ka hoʻoholo ʻana i ka pilikia code.

E ʻoluʻolu e ʻike ʻia kahi papa inoa kikoʻī o nā kikowaena lawelawe kokoke iā ʻoe ma ka KBB Service Center List.

Ke ʻike nei i ka code P0451, pono paha nā mea hana a me nā ʻanuʻu:

• Hoʻopaʻa hoʻomaʻamaʻa.
• Kikohoʻe volt/ohmmika.
• He kumu ʻike hilinaʻi e pili ana i kāu kaʻa, e like me All Data DIY.
• Mīkini puhi (hiki paha).
• E nānā maka aku i nā paipu a me nā laina o ka ʻōnaehana EVAP, a me nā kaula uila a me nā mea hoʻohui.
• E hoʻopaʻa i ka ʻike code a hoʻopaʻa i ka ʻikepili pahu.
• Ke nānā ʻana i ke kaomi ʻōnaehana EVAP me ka hoʻohana ʻana i ke kahe diagnostic (scanner).
• Ke nānā ʻana i ka ʻenekona kaomi EVAP.
• Ke nānā ʻana i nā kaapuni uila me ka hoʻohana ʻana iā DVOM.
• E hoʻololi i nā kaapuni i haki ʻia a pōkole paha inā pono.

E hoʻomanaʻo i hiki i ke kaomi EVAP haʻahaʻa a kiʻekiʻe paha ke kumu o P0451, a hiki ke kumu mai nā pilikia uila a me nā pilikia mechanical.

Nā kuhi hewa

Ke nānā ʻole nei i nā code hewa ʻē aʻe

ʻO kahi hewa maʻamau i ka wā e ʻike ai i kahi code P0451 ʻo ka haʻalele ʻana i nā code pilikia ʻē aʻe. Inā loaʻa nā pilikia me ka ʻōnaehana evaporative emission control (EVAP), hiki ke hoʻoulu ʻia nā code pilikia e pili ana, e like me P0440, P0442, P0452, a pēlā aku. ʻO ka haʻalele ʻana i kēia mau code hou e hopena i ka nalo ʻana i nā hōʻailona koʻikoʻi a paʻakikī i ke kaʻina hana diagnostic.

Nānā ʻike ʻole o ka ʻōnaehana EVAP

ʻO kekahi hewa ʻē aʻe ʻaʻole e nānā pono i ka ʻōnaehana EVAP. I kekahi manawa, hiki ke hoʻopilikia ʻia ka pilikia ma muli o nā hoses i pōʻino, nā mea hoʻohui, a i ʻole nā ​​​​leaks i loko o ka ʻōnaehana. ʻO ka lawe ʻole ʻana i ka manawa e nānā pono i kēia mau ʻāpana hiki ke paʻakikī ke ʻike i ke kumu o ka pilikia.

Mai hana i nā diagnostics piha

Aia ka hewa ma ka ʻoiaʻiʻo ua kaupalena ʻia nā diagnostics i ka heluhelu wale ʻana i nā code hewa a me ka hoʻololi ʻana i ka sensor kaomi EVAP. Hiki ke kumu ʻia kēia code e nā kumu like ʻole, a ʻo ka hoʻololi ʻole ʻia ʻana o ka sensor me ka ʻole o ka diagnostics hohonu hiki ke lilo i mea kūpono ʻole a kumukūʻai.

Pehea ke koʻikoʻi o ke code hewa? P0451?

ʻO Code P0451 kekahi o nā code OBD-II koʻikoʻi loa. ʻO ka maʻamau wale nō ka hōʻailona ʻike ʻia ʻo ke kukui ʻenekini nānā e hele mai ana ma ka dashboard o kāu kaʻa. Eia nō naʻe, ʻoiai ʻaʻohe hōʻailona ʻike ʻia, hiki i kāu kaʻa ke hoʻoheheʻe i nā uahi a me nā mea ʻala maikaʻi ʻole a maikaʻi ʻole. No laila, he mea nui e nānā i kāu kaʻa a hoʻoponopono i ka pilikia no ke olakino a me ka palekana.

He aha ka hoʻoponopono e kōkua i ka hoʻopau ʻana i ke code? P0451?

Pono nā hoʻoponopono hou e hoʻoholo i ke code P0451:

1. Hoʻololi a hoʻoponopono paha i ka ʻenekona kaomi EVAP inā he hewa.
2. E nānā a hoʻololi i ka pāpale pahu wahie inā nalo a poino paha.
3. E hoʻomaʻemaʻe a hoʻololi paha i ka pahu hoʻomaha kaomi pahu wahie inā paʻa a hewa paha.
4. E nānā a hoʻololi i nā paipu a me nā laina EVAP i pohō, luku ʻia, a puhi ʻia paha.
5. Ke hoʻololi nei i kahi pahu kānana kalapona māhā a haki paha inā ua poino.

Manaʻo ʻia e hoʻokō ʻia ka maʻi a me ka hoʻoponopono ʻana e nā ʻenehana loea e like me ka hoʻomaʻamaʻa ʻana iā P0451 e koi i nā lako kūikawā a me ka ʻike.

P0451 - ʻIke pili i ka brand

ʻO ke code pilikia P0451 he code e pili ana i ka ʻōnaehana hoʻoheheʻe mahu. Hiki ke hoʻohana ʻia kēia code i nā ʻano like ʻole o nā kaʻa i lako me ka ʻōnaehana OBD-II. Eia nā wehewehe P0451 no kekahi mau hōʻailona kikoʻī:

1. Chevrolet/GMC: P0451 'o ia ho'i "Evaporative Emission System Pressure Sensor/Switch". He code kēia e pili ana i ka ʻōnaehana hoʻoheheʻe evaporative.
2. Ford: Ua unuhi ʻia ʻo P0451 ma ke ʻano he "Fuel Tank Pressure Sensor". Hōʻike kēia code i nā pilikia me ke kaomi i loko o ka ʻōnaehana pahu wahie.
3. chinatown: P0451 'o ia ho'i "EVAP System Pressure Sensor Error." Pili kēia code i ka ʻōnaehana EVAP a me kona kaomi.
4. Volkswagen/Audi: Hiki ke wehewehe ʻia ʻo P0451 ma ke ʻano he "EVAP System Pressure Sensor". ʻO kēia ma muli o ka ʻōnaehana hoʻokele evaporative emissions.
5. Dodge/Ram: P0451 'o ia ho'i "EVAP System Pressure Sensor Error." Pili kēia code i ka ʻōnaehana EVAP.

E ʻoluʻolu e ʻokoʻa iki ka wehewehe kikoʻī o ke code ma muli o ka hana a me ke ʻano hoʻohālike o kahi kaʻa, no laila e ʻōlelo mau ʻia e nānā i ka lawelawe a me ka manual hoʻoponopono no kāu kaʻa kikoʻī a i ʻole e nīnau i kahi mechanic kūpono no ka ʻike pololei a me ka hoʻoponopono. .
