ʻO P004B Turbo / Supercharger Boost Control B Circuit Performance Range

ʻO P004B Turbo / Supercharger Boost Control B Circuit Performance Range

Papa Kuhikuhi DTC OBD-II

ʻO Turbocharger / Supercharger Boost Control Circuit Performance Range "B"

He aha keʻano o kēia?

ʻO kēia Code Diagnostic Trouble Code (DTC) kahi code transmic generic, ʻo ia hoʻi pili i nā kaʻa i hoʻolako ʻia me OBD-II i loaʻa kahi supercharger a i ʻole turbocharger (Ford Powerstroke, Chevrolet GMC Duramax, Toyota, Dodge, Jeep, Chrysler, VW, a pēlā aku.) . D.). ʻOiai he laulā i ke ʻano, ʻokoʻa paha nā kaʻina hana kūikawā i ka hilinaʻi ʻana i ka brand / model.

ʻO nā turbocharger a me nā supercharger he mau ea e hoʻoikaika i ka ea i loko o kahi mīkini e hoʻonui i ka mana. Hoʻokuʻu ʻia nā superchargers mai ka crankshaft engine e ke kāʻei, aʻo nā turbocharger e alakaʻi ʻia e nā kinoea hoʻopau engine.

Hoʻohana ka nui o nā kaʻa turbocharged i kahi turbocharger geometry variable (VGT) i kapa ʻia. ʻO kēia ʻano turbocharger he mau pahi hoʻoliʻiliʻi a puni ka waho o ka turbine i hiki ke wehe a pani ʻia e hoʻololi i ka nui o ka hoʻoulu hoʻoikaika. ʻAe kēia i ka turbo e kāohi kūʻokoʻa i ka wikiwiki o ka ʻenekini. Wehe ʻia nā wana i ka wā ma lalo o ka māmā o ka ʻenekini a hāmama ke piʻi ka nui o ka ukana. Hoʻopili ʻia ke kūlana pahi e ka modula kaohi powertrain (PCM), ma o ka solenoid a me ka motika e hoʻokele uila ai. Hoʻoholo ʻia ke kūlana o ka turbocharger me ka hoʻohana ʻana i kahi sensor kūlana kūikawā.

Ma nā kaʻa e hoʻohana ana i kahi turbocharger hoʻoliʻiliʻi kuʻuna a i ʻole supercharger, kaohi ʻia ka hoʻonui ma o kahi wastegate a i ʻole wastegate. Wehe ʻia kēia kiwikā e hoʻokuʻu i ka pihi hoʻonui. Nānā ka PCM i kēia ʻōnaehana me kahi mea hoʻoulu puʻe hoʻonui.

No kēia DTC, hōʻike ʻo "B" i kahi pilikia i kahi ʻāpana o ka ʻōnaehana pūnaewele ʻaʻole kahi hōʻailona kikoʻī a i ʻole ʻāpana.

Hoʻonohonoho ʻia ʻo Code P004B i ka manawa e ʻike ai ka PCM i kahi pilikia hana me ka solenoid hoʻoikaika hoʻoikaika, inā paha e hoʻohana ana ka ʻenekini turbocharging VGT a i ʻole turbocharger / supercharger kuʻuna.

Kekahi ʻano o ka turbocharger hoʻonui i ka pā solenoid kiwikā:

E pili pū ana me Turbo / Supercharger Pake DTCs:

• P004A Turbocharger / Supercharger Boost Control «B» Kaapuni / wehe
• P004C Turbocharger / Supercharger Boost Control «B» Kaapuni Hakahaka
• P004D Turbocharger / Supercharger Boost Control «B» Kūlana Kiʻekiʻena
• P004F Turbocharger / Supercharger Boost Control «B» Kaapuni waena

Ka nui o nā code a me nā ʻōuli

ʻO ka paʻakikī o kēia mau code he haʻahaʻa a koʻikoʻi. I kekahi mau hihia, hiki i nā pilikia turbocharger/supercharger ke hōʻeha nui i ka ʻenekini. Manaʻo ʻia e hoʻoponopono koke i kēia code.

Pākuʻi ʻia paha nā ʻōuli o ke code P004B:

• ʻAʻole lawa ka hoʻonui ʻana e hopena ai i ka hana ʻana o ka ʻenekini
• ʻO ka hoʻonui nui ʻana e hopena ai i ka pāhū ʻana a me ka hōʻino ʻia ʻana o nā ʻenekini
• E nānā i ke kukui ʻenekini

kumu

Nā kumu kūpono no ka hoʻonohonoho ʻana i kēia code:

• Hoʻonui hoʻonui kaomi / turbocharger kūlana mīkiniʻimi
• Defence turbocharger / supercharger
• Pāleo hano solenoid
• Nā pilikia pili uila
• PCM hemahema
• Holo nā vacuum inā kaohi ka pahu e ka hakahaka

Nā diagnostics a me nā kaʻina hana hoʻoponopono

E hoʻomaka me ka nānā ʻana i ka ʻōnaehana turbocharger a me ka ʻōnaehana hoʻokele turbocharger. E nānā i nā pilina leʻa, nā uea ʻino, nā leakī holo, a pēlā aku. Inā loaʻa ʻole kahi mea, pono ʻoe e hoʻomau i nā diagnostics ʻōnaehana step-by-step.

ʻO ka mea aʻe kahi hana maʻamau e like me ka hoʻāʻo ʻana o kēia pāʻālua ʻokoʻa mai kahi kaʻa a kahi kaʻa. E hōʻoia pono i ka ʻōnaehana, pono ʻoe e nānā i ka flowchart diagnostic diagnostic a ka mea hana.

Hōʻoia i ka hana ʻōnaehana ma ke kauoha ʻana i ka solenoid kaohi e hoʻonohonoho hou me kahi mea hana scanner bidirectional. E hoʻokiʻekiʻe i ka wikiwiki o ka ʻenekini a i kahi o 1,200 rpm a kāpae i ka solenoid a pio hoʻi. Pono kēia e hoʻololi i ka RPM mīkini a pono e loli ke kūlana sensor PID pū kekahi. Inā piʻi ka wikiwiki, akā ʻaʻole e loli ke kūlana PID / kaomi kaomi, e kānalua i kahi pilikia i ka sensor a i ʻole kāna kaapuni. Inā ʻaʻole e loli ka RPM, kānalua ka pilikia me ka solenoid kaohi, turbocharger / supercharger, a i ʻole nā ​​uea.

• E hoʻāʻo i ke kaapuni: e nānā i ka mana a me ka honua ma ka solenoid. Nānā: Ke hana nei i kēia mau hoʻokolohua, pono e kauoha ʻia ka solenoid ON me kahi mea scan. Inā nalowale ka mana a i ʻole ka lepo, pono ʻoe e haki i ke kiʻikuhi uila o ka hale hana e hoʻoholo ai i ke kumu.
• E hōʻoia i ka turbocharger / supercharger: e hoʻoneʻe i ka lawe ʻana o ka ea e nānā i ka turbocharger / supercharger no ka pohō a i ʻole nā ​​ʻōpala. Inā loaʻa ka pohō, hoʻololi i ka anakahi.
• E hōʻoia i ke kūlana / kaomi puʻe a me ke kaapuni: i ka hapanui o nā hihia e hoʻopili ʻia ʻekolu mau kaula i ke kiʻikuhi kūlana: ka mana, ka honua a me ka hōʻailona. E nānā pono aia ʻekolu.
• E hoʻāʻo i ka solenoid kaohi: I kekahi mau hihia, hiki iā ʻoe ke hoʻāʻo i ka solenoid ma ka nānā ʻana i kona kūʻē kūloko me kahi ohmmeter. E ʻike i ka ʻike hana hou no ka hale hana. Hiki iā ʻoe ke hoʻohui i ka solenoid i ka mana a me ka honua e hoʻāʻo inā holo pono ia.

Pono i ke kōkua hou me ke code p004b?

Inā makemake ʻoe i kōkua me DTC P004B, 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.
