Papa Kuhikuhi DTC OBD-II

Exhaust Gas Recirculation Mahana Sensor Circuit Range / Hana

He aha keʻano o kēia?

ʻO kēia kahi Code Diagnostic Trouble Code (DTC) a pili pinepine ʻia i nā kaʻa OBD-II. Hoʻopili paha kēia akā ʻaʻole kau palena ʻia ia Mazda, VW, Audi, Mercedes Benz, Ford, Dodge, Ram, etc.

ʻOiai he laulā, ʻokoʻa paha nā kaʻina hana pololei e pili ana i ka makahiki hoʻohālikelike, hana, hoʻohālikelike, a me ka hoʻonohonoho hoʻonohonoho.

Ma mua o ka hoʻokō pono ʻana o nā ʻōnaehana recirculation kinoea hoʻopau i loko o nā kaʻa i nā makahiki 1970, hoʻopau ikaika nā ʻenekini i ka wahie unburned a hoʻokuʻu ʻia i ka lewa. I kēia mau lā, ma ka ʻaoʻao ʻē aʻe, pono i kahi kaʻa i kahi pae emission e hoʻomau i ka hana.

ʻO ka hoʻohana ʻana o nā ʻōnaehana recirculation kinoea hoʻopau ka hopena i nā hōʻemi emissions nui ma o ka recirculate ʻana i nā kinoea hou mai ka maha a me / a i ʻole nā ​​ʻāpana ʻē aʻe o ka ʻōnaehana hoʻopau a me ka recirculate ʻana a i ʻole ke puhi hou ʻana iā lākou i mea e puhi pono ai mākou i ka wahie a mākou e uku ai. e ka lakou hooikaika paakiki. loaʻa kālā!

ʻO ka hana o ka EGR mahana sensor e hāʻawi i kahi ala no ka ECM (module hoʻokele ʻenekini) e nānā i ka mahana EGR a / a i ʻole e hoʻoponopono i ke kahe e like me ka pahu EGR. Hana maʻalahi ʻia kēia me kahi mea ʻike ʻano resistor ʻano kuʻuna.

Hōʻike paha kāu mea hana scan OBD (On-Board Diagnostic) i ka P040B a me nā code pili e pili ana i ka wā e ʻike ai ka ECM i kahi hana hewa ʻole i ka EGR wela sensor a i ʻole kāna mau kaapuni. E like me kaʻu i ʻōlelo ai ma mua, hoʻokomo ka ʻōnaehana i ka wela wela, ʻaʻole wale ia, akā ke hana nei ʻoe me kekahi o nā wahi wela o ke kaʻa, no laila e akahele i kahi o kou mau lima / manamana lima, ʻoiai me ka ʻenekini no kahi manawa pōkole. . manawa.

Hoʻonohonoho ʻia ka Code P040B Exhaust Gas Recirculation Temperature Sensor Circuit Range / Performance e ka ECM ke ʻike ʻia kahi pilikia ma waho o ka pae a i ʻole i kahi hana i ka EGR "A" circuit sensor sensor. E kūkākūkā i kāu manuale hoʻoponopono kaʻa kikoʻī e hoʻoholo ai i ka ʻāpana o ke kaulahao ʻo "A" no kāu noi kikoʻī.

He aha ke koʻikoʻi o kēia DTC?

Pili ka nui ma luna o kāu pilikia ponoʻī, akā ʻaʻole wau e hoʻohālikelike iā ia ma ke ʻano koʻikoʻi no ka mea ua hoʻokomo ʻia ka ʻōnaehana holoʻokoʻa i loko o nā kaʻa ma ke ʻano he hoʻolālā hoʻemi emission. ʻO ka ʻōlelo ʻia, ʻaʻole maikaʻi nā kahe kahena no kāu kaʻa, ʻaʻole pū kahe a hewahewa paha nā mea ʻike EGR, no laila ke kī ma aneʻi ma mua o ka wā ma hope.

ʻO kahi laʻana o kahi mea hoʻomehana kinoea recirculation wela sensor:

He aha kekahi o nā ʻōuli o ke code?

Nā hōʻailona o kahi P040B pilikia code e hoʻopili pū paha:

• Smog mokuʻāina / panalāʻau i kūleʻa a i ʻole ka hoʻāʻo ʻana
• Halulu ʻenekini (kīkēkē, hoʻokani, kani, a pēlā aku.)
• Pau loa ka luhi
• ʻAʻala ʻaʻano Keu

He aha kekahi o nā kumu maʻamau no ke code?

Nā kumu no kēia code mīkini ʻenekini P040B e hoʻopili pū paha:

• Mea hōʻino a hōʻino ʻia paha i kahi mea ʻike pumehana EGR.
• Hoʻopau kahe recirculation kinoea mīkini ʻikepili gasket
• Pāhaʻi a hoʻokahe paha i ka paipu hoʻopau kahi i hoʻonohonoho ʻia ai ka mea ʻike
• Uwea uea mea kaua a me / a i ʻole mea mīkini paʻi
• Nā uea poino (ke kaʻa hāmama, pōkole i ka mana, pōkole i ka lepo, a pēlā aku.)
• Pākuʻi poino
• ECM (Mīkini Mīkini Mīkini) pilikia
• Pili pili ʻole

He aha kekahi mau kaʻina e troubleshoot i ka P040B?

Ka anu u kumu # 1

ʻO ka mea mua aʻu e makemake ai e hana ma aneʻi e nānā i nā mea āpau a mākou e ʻike ai ma ka nānā wale ʻana i ka mea ʻike a me ka ʻōnaehana EGR e pili ana, e ʻimi kikoʻī ana i nā kahe o ka luhi. E nānā pū me ke kiʻiona a me kāna mea kaua ʻoiai ʻoe ma laila. Hoʻomanaʻo i ka mea aʻu i ʻōlelo ai e pili ana i kēlā mau mahana wela? Hiki iā lākou ke hōʻino i ka uea a me nā uea kāpili, no laila e nānā pono iā lākou.

Manaʻo kōkua: Hiki i nā soot ʻeleʻele ke kuhikuhi i kahi kulu o ka hale i loko.

Ka anu u kumu # 2

Nui nā pilikia EGR aʻu i ʻike ai i ka wā ma mua i hoʻokumu ʻia e ka soot build-up i ka hoʻopau, a hiki i nā kumu he nui (mālama maikaʻi ʻole, maikaʻi maikaʻi ʻole ka wahie, a pēlā aku.). ʻAʻole kēia he ʻokoʻa i kēia hihia, no laila he mea kōkua paha e hoʻomaʻemaʻe i ka ʻōnaehana EGR, a i ʻole ka mea ʻike i ke ana wela. E makaʻala i nā sensor i hoʻonohonoho ʻia i nā ʻōnaehana hoʻopau hiki ke ʻike i ka ʻīlī ʻia ke hoʻāʻo nei e wehe.

Hoʻomanaʻo i kēia mau mea ʻike i nā fluctuations o ka wela nui, no laila kahi wela liʻiliʻi e hoʻohana ana i ka lama OAC (ʻaʻole no ka layman) hiki ke kōkua i ka nāwaliwali o ka sensor. Ma hope o ka hemo ʻana i ka mīkini paʻi, e hoʻohana i kahi mea hoʻomaʻemaʻe carburetor a i ʻole huahana like e hoʻomomona pono ai i ka soot. E hoʻohana i ka palaki uea e lawe aku i ka soot nui mai nā wahi i hōʻiliʻili ʻia. Ke hoʻouka hou ʻana i kahi mea hoʻomaʻemaʻe maʻemaʻe, e hoʻopili pono i ka hoʻopili anti-seize i nā pae e pale ai i ke kani ʻana.

HOOLAHA. ʻO ka mea hope āu e makemake ai e hana ma ʻaneʻi, ʻo ia ke uhaki i ka mea ʻike i loko o ka manifold/exhaust manifold. He kuhi hewa paha kēia, no laila e lawe i kou manawa i ka wā e wāwahi ai i ka sensor.

Ka anu u kumu # 3

Hōʻoia i ka pono o ke kiʻikuhi ma ke ana ʻana i nā waiwai uila maoli me nā waiwai i makemake ʻia o ka mea hana. Hana i kēia me ka multimeter a hāhai i nā kaʻina hana hōʻoia o ka mea hana.

Nā kūkākūkā DTC e pili ana

• ʻAʻohe kumuhana pili i kēia manawa i kā mākou kolamu. Kau i kahi kumuhana hou ma ke kolamu i kēia manawa.

Pono i kōkua hou me kahi code P040B?

Inā makemake ʻoe i kōkua me DTC P040B, 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.
