P0170 Fuel Trim Malunction (Panakō 1)

Pepa ʻikepili pilikia P0170 OBD-II

Ka Hana Hana Hana Pūnaewele ʻAila ʻAi ʻole (Bank 1)

He aha keʻano o kēia?

ʻO kēia Code Diagnostic Trouble Code (DTC) kahi code transmic generic, ʻo ia hoʻi pili i nā kaʻa lako OBD-II. ʻOiai he laulā i ke ʻano, ʻokoʻa paha nā kaʻina hana kūikawā i ka hilinaʻi ʻana i ka brand / model.

ʻOi aku ka maʻamau o kēia code ma kekahi mau kaʻa kaʻa ma mua o nā mea ʻē aʻe. Ua hoʻohui au i ka ʻike kikoʻī ʻo Mercedes-Benz i ke kākau ʻana i kēia ʻatikala me he mea lā ʻo MB (a me VW) ka mea maʻalahi i ka loaʻa ʻana o kēia wahi P0170 me nā code misfire a i ʻole nā ​​ʻoki ʻoki wahie ʻē aʻe. ʻO ka manaʻo P0170 aia kekahi pilikia me ka lewa o ke kamepiula: ka lakio wahie.

Hōʻike ia i ka hōʻea ʻana o nā wahie wahie i kā lākou wahie hoʻohui palena ʻoiai e hoʻāʻo nei e uku no kahi kūlana waiwai a ʻike ʻia paha. Ke hōʻea nā wahie wahie i ka palena ʻoki piha waiwai, hoʻonohonoho ka PCM (module mana mana powertrain) iā P0170 e hōʻike i kahi pilikia a i ʻole hana hewa ʻole i nā ʻoki wahie. Aia paha he P0173 ke kuhikuhi nei i ka hewa like, akā ma ka lālani ʻelua.

Nā hōʻailona o ka hewa P0170

ʻO nā ʻōuli o kahi pāʻālua pilikia P0170 e hoʻopili pū paha:

• MIL (Kahi Hōʻike Mana Mea Hana) Lamplight
• Hoʻomaka a kū
• ʻO ka hoʻokele waiwai wahie maikaʻi ʻole
• Puhi ʻeleʻele ma ka paipu hoʻopau
• Wobble / misfire ma ka palaualelo a i ʻole ma lalo o ka ukana

kumu

ʻO nā kumu i hiki ke hoʻopili ʻia me ka leki uila, ka leha ea ʻole i ana ʻia. ʻO ka ʻaila ʻaila wahie me ka hoʻopiha ʻana i ka wai i ka hoses uku o ka turbocharger (inā lako ʻia) Paha hemahema O2 sensor (Pono paha ʻo Mercedes me ka hoʻopili ʻana me kahi pono hana scanning M-Benz). Ka hoʻohaumia aila ma ka hoʻopili MAF a i ʻole nā ​​mea hoʻopili ʻo O2. E nānā pū hoʻi i nā uila uila, cam a me nā mea ʻoloke, a me ka mea ʻike aila no nā liu e ʻae ai i ka ʻaila e komo i ka hao uila. Kaha MAF (MAF) mīkini paʻi (ʻoi loa ma Mercedez-Benz a me nā kaʻa ʻē aʻe o ʻEulopa. Nui nā pilikia me nā mea ʻike MAF koho ʻole). Mea hoʻoponopono kaomi uila wahie maikaʻi ʻole Leakage i loko o ka solenoids regulator wanaʻao (Mercedes-Benz).

MEA KAHAKAHA: No kekahi mau hiʻohiʻona Mercedes-Benz, aia kahi lawelawe hoʻomanaʻo no ka hose crankcase breather hose ma lalo o ka nui o ka lawe. E hōʻoia no nā kahe / mau māwae a nānā i ka hana o ka nohona ma ka paipu. E holo wale ka pahu kiwikā i hoʻokahi ala.

Hiki ke hoʻonā i ka P0170

Pono e ʻōlelo ʻia ma waho pono o ka ʻōpeʻapeʻa ʻo ka pilikia maʻamau e pili ana i kēia code ʻo ka mīkini MAF a i ʻole ka mika kahe o ka ea. Heʻoiaʻiʻo loa kēia no Mercedes-Benz, Volkswagen a me nā kaʻa ʻē aʻe o ʻEulopa. I ka manawa o ke kākau ʻana, ʻaʻole ʻike ʻoe i kēia code me nā kaʻa ʻAmelika a ma ka liʻiliʻi o nā kaʻa ʻAsia, a ʻo ka ʻoiaʻiʻo, ʻaʻohe oʻu manaʻo no ke aha. Me he mea lā iaʻu ʻaʻole ka PCM (Powertrain Control Module) i hoʻohana ʻia e kekahi mau mea hana kaʻa ʻEulopa e hoʻonohonoho iā DTC P0170 (a i ʻole P0173) ʻaʻole hoʻohana maʻalahi ʻia e nā mea hana kaʻa ʻAmelika. ʻO nā code maʻamau ʻo P0171, 0174, 0172, 0175, i hoʻonohonoho ʻia e pili ana i nā hewa ʻoki wahie ma nā kaʻa ʻAmelika. Heʻuʻuku loa ka ʻike e pili ana i nā ʻano no ka hoʻopili ʻana no P0170 a i ʻole P0173, akā ʻo ka ʻike i loaʻa e like me ka aneane pohihihi no nā ʻano hoʻoulina P0171,4,2 & 5. Manaʻo wau he kumu kēia no kēia, akā ʻaʻole hiki iaʻu ke kiʻi i kekahi e ʻōlelo iaʻu he aha ia. ʻO ka like ma waena o lākou ke kumu o ka ʻike pinepine ʻole ʻana i kēia pāʻālua ma nā kaʻa home. He pono ʻole wale ia. No laila, e waiho maʻalahi, inā he P0170 kāu, ua ʻike kāu PCM ua hōʻea nā ʻāmi wahie i kā lākou palena ʻoki piha. ʻO ke kumu, ʻo ia ka hoʻohui o ka wahie e hoʻāʻo a uku i ke kūlana maikaʻi ʻole, maoli a ʻike ʻia paha.

Inā loaʻa iā ʻoe kēia code a hiki i kahi mea hana scan, e hoʻomaopopo i ka heluhelu ʻana o ka gram / kekona mai ka mīkini MAF. E loli ka heluhelu ʻana mai kahi kaʻa a kahi kaʻa, no laila loaʻa iā ʻoe kahi hana maikaʻi. E pili wau me ka mea maʻamau ʻo Mercedes (1.8L) ʻoiai ʻo lākou ka pilikia nui. Kuhi e ʻike ma ka hana ʻole 3.5-5 g / s (kūpono loa). Ma 2500 rpm me ka ʻole o ka ukana, aia ma waena o 9 a me 12 g / s. I kahi hōʻike alanui WOT (Wide Open Throttle), 90 g / s a ​​ʻoi aku ke kiʻekiʻe. Inā ʻaʻole ia ma ka kikoʻī, e pani. E akahele me Ebay MAF. ʻAʻole hana pinepine lākou e like me nā kikoʻī OE. Inā nānā ʻia ka MAF a ʻaʻole komo ka ʻaila i ka mea hoʻopili, e nānā i ka kaomi wahie a e ʻike ʻole ʻaʻohe puka i loko a i ʻole ma waho o ka mea hoʻokele. E hōʻoia i nā lekiō hakahaka āpau a e ʻike pono ʻaʻole i haki, hoʻokaʻawale, a nalowale paha. E hōʻoia no ka leki ʻana mai ka gask manifold a me nā haki i ka paukū lako air. Inā turbocharged ka ʻenekini, e nānā inā maikaʻi nā hoses a me ka ʻole o nā kahe. Hiki i ke kahe turbo hoses ke alakaʻi i kahi kūlana waiwai. E hōʻoia i ke ʻano o ka pulina hanu crankcase ma lalo o ka manifold manifold a me ka hana o ka valve non-return i ka hose. (Ma lalo o ke kumu) Hiki i kahi mea ʻikepili O2 maikaʻi ʻole ke kumu i kahi pāʻālua P2 a i ʻole P0170. Hoʻoponopono i ke kumu o ka liʻī o ka aila a hoʻololi i ka aila o O0173 i hoʻohaumia ʻia i ka aila.

Kuhi hewa P0170

Pono i kōkua hou me kāu code p0170?

Inā makemake ʻoe i kōkua me DTC P0170, 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.
