P2271 O2 Sensor Sign Bias / Pākuʻi Rich Bank 1 Sensor 2

P2271 O2 Sensor Sign Bias / Pākuʻi Rich Bank 1 Sensor 2

Papa Kuhikuhi DTC OBD-II

Ua hoʻohuli / paʻa ʻia ka hōʻailona o O2 i kahi hui waiwai, ka panakō 1, ka mīkini paʻi 2

He aha keʻano o kēia?

ʻO kēia kahi code transmic generic e pili ana i nā kaʻa OBD-II āpau mai ka makahiki 1996. Pākuʻi paha nā kaʻa kaʻa akā ʻaʻole kau palena ʻia ia VW, Honda, Dodge, Hyundai, Ford, GMC, Acura, a pēlā aku.

Kuhi kēia Diagnostic Trouble Code (DTC) P2271 i ke kiʻina O2 (oxygen) Postkatalitichesky neutralizer series №1, №2 mīkiniʻimi. Hoʻohana ʻia kēia sensor post-cat e nānā i ka pono o ka hoʻololi catalytic. ʻO ka hana a ka mea hoʻololi i ka hoʻoliʻiliʻi i nā hoʻokuʻu hoʻokuʻu. Keʻike ka PCM i ka hōʻailona mai ka mea ʻike O2 e like me ka offset a i ʻole hang Rich Rich, hoʻonohonoho i kēia DTC.

ʻO DTC P2271 e pili ana i ka mea ʻike i lalo (ma hope o ka mea hoʻololi catalytic), sensor #2 ma ka panakō #1. ʻO ka panakō #1 ka ʻaoʻao o ka ʻenekini i loaʻa ka cylinder #1. Aia paha ke kolu o ka sensor ma ka puka, inā he pilikia kēia, ua hoʻonohonoho ʻia ʻo P2275.

ʻ tellslelo kēia code iā ʻoe i ka hōʻailona i hāʻawi ʻia e kahi sensor oyxgen kikoʻī i paʻa i ka hui momona (ʻo ia hoʻi he ea liʻiliʻi i ka hoʻopau.

ʻO ka sensor oxygen oxygen maʻamau O2:

nā hōʻailona

ʻO nā manawa kūpono, ʻaʻole ʻoe e ʻike i kekahi pilikia e lawelawe ana no ka mea ʻaʻole kēia ka mea ʻike # 1. E ʻike ʻoe i ke kukui mai o ke kukui o ke kaha uila (MIL). Eia nō naʻe, i kekahi mau manawa, holo ʻenekini paha ka ʻenekini.

Nā kumu kumu

Hiki i nā kumu no kēia DTC ke komo pū:

• Kaha a hewahewa paha HO2S2 mīkiniʻimi (sensor 2)
• ʻO ka pilikia HO2S2 Wili / Kaapuni
• Kaomi wahie kūpono ʻole
• Mea hoʻopili kīnā ʻole
• Mea hoʻoheheʻe ʻenekini pū kekahi
• Pāpale solenoid hoʻomaʻemaʻe kīnā ʻole
• PCM ma waho o ke kauoha

Nā diagnostics a me nā kaʻina hana hoʻoponopono

Nānā ʻike maka i nā pilina a me nā mea hoʻopili no ka hoʻowahāwahā, wili / abraded / kinked uea, kūlou / hoʻokuʻu ʻia nā pin uea, puhi ʻia a / a i ʻole nā ​​kaula iʻaʻa. Hoʻoponopono a pani paha e like me ka mea e pono ai.

E hōʻoia no nā kahe kahe a i ʻole nā ​​pilikia ʻē aʻe a hoʻoponopono e like me ka mea e pono ai.

Ke hoʻohana nei i kahi mika volt ohm mika (DVOM) i hoʻonohonoho ʻia i ohm, e hoʻāʻo i nā mea hoʻopili o ka pale pale no ke kūpaʻa. Hoʻohālikelike me nā kikoʻī hana. Hoʻololi a hoʻoponopono hou paha e like me ka mea e pono ai.

Inā hiki iā ʻoe ke kiʻi i ka mea hana scan kiʻekiʻe, e hoʻohana iā ia e nānā i ka heluhelu ʻana o ka sensor e like me ka ʻike a ka PCM (ke holo nei ka ʻenekini i ka mahana hana maʻamau i ke ʻano loop loop). ʻIke ka ʻenekini oxygen hahana hope (HO2S) i nā loli uila ma waena o 0 a me 1 volt, no kēia DTC ʻike paha ʻoe i ka uila i hoʻopaʻa ʻia ma 1 V. ʻO ka hoʻohuli ʻana i ka ʻenekini ka mea e hoʻololi ai ka uila uila (react).

ʻO nā hoʻoponopono maʻamau no kēia DTC kahi leha air exhaust, kahi pilikia me ka uea sensor / uea, a i ʻole ke kiʻikuhi ponoʻī. Inā ʻoe e pani nei i kāu mīkini ʻo O2, e kūʻai i kahi mea ʻike ʻo OEM (inoa inoa) no nā hopena maikaʻi loa.

Inā ʻoe e hoʻoneʻe nei i ka HO2S, e nānā i ka haumia mai ka wahie, aila ʻenekini, a me ka coolant.

Nā manaʻo troubleshooting ʻē aʻe: E hoʻohana i kahi mea hoʻāʻo kaomi wahie, e nānā i ka kaomi wahie ma ka pahu Schrader ma ka hao wahie. Hoʻohālikelike me ka kikoʻī a ka mea hana. Nānā i ka kiwikā solenoid purge. E nānā i nā mea hoʻopili wahie. E nānā i nā paukū coolant no nā kulu.
