Code pilikia OBD-II - P0121 wehewehe ʻenehana

P0121 - ʻIke Kūlana Throttle / Hoʻololi i kahi Kaapuni Kaapuni / Pilikia hana.

Hana ʻia ʻo DTC P0121 i ka wā e ʻike ai ka module control engine (ECU, ECM a i ʻole PCM) i kahi sensor throttle position hewa (TPS - throttle position sensor), i kapa ʻia he potentiometer, e hoʻouna ana i nā waiwai hewa e like me nā lula.

He aha ke ʻano o ka code pilikia P0121?

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.

ʻO ka mea ʻike kūlana throttle kahi potentiometer e ana i ka nui o ka wehe ʻana o ka throttle. Ke wehe ʻia ka throttle, piʻi ka heluhelu (ana i nā volts).

Hāʻawi ka modula mana powertrain (PCM) i kahi hōʻailona kuhikuhi 5V i ka Throttle Position Sensor (TPS) a maʻa mau i ka honua. Ana lehulehu: moloā = 5V; piha piha = 4.5 volts. Inā ʻike ka PCM ʻoi aku ka nui o ka huina throttle a i ʻole ka liʻiliʻi ma mua o kahi no kekahi RPM, e hoʻonohonoho ia i kēia code.

Nā hōʻailona kūpono paha

ʻO nā ʻōuli o kahi pāʻālua pilikia P0121 e hoʻopili pū paha:

  • Ua hoʻomālamalama ʻia ke kukui hōʻailona malunction (MIL) (E nānā koke i ke kukui a me ka lawelawe ʻenekini)
  • Kūleʻa intermittent i ka wā e hōʻeleu ana a i ʻole decelerating
  • Ke puhi nei i ka uahi ʻeleʻele ke wikiwiki
  • ʻAʻole hoʻomaka
  • E hoʻā i ke kukui hoʻomaʻamaʻa ʻenekini pili.
  • ʻO ka hana ʻino maʻamau, hiki ke alakaʻi i ke ahi.
  • Nā pilikia me ka hoʻokē ʻai ʻana.
  • Nā pilikia me ka hoʻomaka ʻana i ka ʻenekini.
  • Hoʻonui ka hoʻohana wahie.

Eia naʻe, hiki ke ʻike ʻia kēia mau hōʻailona me ka hui pū ʻana me nā code hewa ʻē aʻe.

Nā kumu o ke code P0121

ʻO ka throttle position sensor ka hana o ka nānā ʻana a me ka hoʻoholo ʻana i ke kihi wehe o kēia damper. Hoʻouna ʻia ka ʻike i hoʻopaʻa ʻia i ka ʻāpana hoʻokele engine, nāna e hoʻohana iā ia e helu i ka nui o ka wahie e pono ai ke hoʻokomo ʻia i loko o ke kaapuni no ka loaʻa ʻana o ka puhi ahi. Inā ʻike ka module control engine i kahi kūlana throttle erratic ma muli o kahi ʻenekona kūlana hewa, e hoʻonohonoho ʻokoʻa ʻo DTC P0121.

Kuhi paha ka code P0121 i hoʻokahi a ʻoi paha o nā hanana aʻe i kū aʻe:

  • ʻAʻole hana ʻino ke kūlana throttle.
  • ʻO ka hewa uwea ma muli o ka uwea ʻole a i ʻole ke kaapuni pōkole.
  • Pilikia uwila kūlana throttle position sensor.
  • ʻO ka loaʻa ʻana o ka makū a i ʻole ke komo ʻana o waho e pili ana i ka hana o ka ʻōnaehana uila.
  • Nā mea hoʻohui hewa.
  • ʻO ka hana ʻino o ka module control engine, ka hoʻouna ʻana i nā code hewa.
  • He kaapuni hāmama waena kā ka TPS a i ʻole kahi pōʻai pōkole kūloko.
  • Ke ʻānai nei ka mea kaua, e hoʻomaka ana i kahi kaapuni ākea a pōkole paha i nā uwea.
  • Pili maikaʻi ʻole ma TPS
  • ʻO PCM maikaʻi ʻole (liʻiliʻi paha)
  • Ka wai a i ʻole ka popopo i ka hoʻopili a i ʻole ka mea ʻike

Nā hāʻina hiki

1. Inā hiki iā ʻoe ke komo i kahi mea hana scan, e ʻike i nā heluhelu heluhelu a me ka throttle ākea (WOT) ākea no ka TPS. E ʻike pono kokoke lākou i nā kikoʻī i ʻōlelo ʻia ma luna. Inā ʻaʻole, e puku i ka TPS a nānā hou.

2. E hōʻoia no ka wehe waena a i ʻole ke kaapuni pokole i ka hōʻailona TPS. ʻAʻole hiki iā ʻoe ke hoʻohana i kahi mea nānā scan no kēia. Pono ʻoe i oscillator. ʻO kēia no ka lawe ʻana o nā pono hana i nā laʻana o nā heluhelu like ʻole ma hoʻokahi a i ʻole ʻelua mau laina o ka ʻikepili a haʻo paha e haʻalele i nā hāʻule intermittent. E hoʻohui i ka oscilloscope a nānā i ka hōʻailona. E kū aʻe a hina mālie, me ka haʻalele ʻole a protruding paha.

3. Inā ʻaʻohe pilikia i loaʻa, hana i kahi hoʻokolohua wiggle. Hana i kēia ma ka wiggling ʻana i ka mea hoʻopili a me ka pale ʻana i ka nānā ʻana i ke kumu. Holo i waho? Inā pēlā, e pani i ka TPS a nānā hou.

4. Inā ʻaʻohe ou hōʻailona TPS, e nānā no kahi kuhikuhi 5V ma ka hoʻopili. Inā loaʻa, e hoʻāʻo i ka pōʻai honua no ka pōʻai ākea a pōkole paha.

5. E hōʻoia i ka pōʻaiapuni hōʻailona ʻaʻole 12V. ʻAʻole pono ia e loaʻa i ka uila uila. Inā pēlā, e nānā i ke kaapuni no kahi pōkole i ka uila a hoʻoponopono.

6. E nānā i ka wai i ka hoʻopili a hoʻololi i ka TPS inā pono.

Nā Sensor TPS a me nā DTC Kaapuni hou: P0120, P0122, P0123, P0124

Kōkua hoʻomaikaʻi

Ma hope o ka lawe ʻia ʻana o ke kaʻa i ka hale hana, e hana maʻamau ka mechanic i kēia mau hana e ʻike pono ai i ka pilikia:

  • E ʻimi no nā code hewa me kahi scanner OBC-II kūpono. Ke hana ʻia kēia a ma hope o ka hoʻoponopono hou ʻana i nā code, e hoʻomau mākou i ka hoʻāʻo ʻana ma ke ala e ʻike ai inā ʻike hou ʻia nā code.
  • Ke nānā ʻana i ke kūlana throttle.
  • Nānā i nā ʻāpana ʻōnaehana kelepona.
  • ʻO ka nānā ʻana i ka valve throttle.
  • Ke ana i ke kū'ē o ka mea ʻike me kahi mea hana kūpono.
  • Nānā i nā mea hoʻohui.

ʻAʻole ʻōlelo ʻia ka hoʻololi wikiwiki ʻana i ka sensor throttle, no ka mea, aia paha ke kumu o ka P0121 DTC i kahi mea ʻē aʻe, e like me ke kaapuni pōkole a i ʻole nā ​​​​mea hoʻohui maikaʻi ʻole.

ʻO ka mea maʻamau, ʻo ka hoʻoponopono e hoʻomaʻemaʻe pinepine i kēia code penei:

  • Hoʻoponopono a hoʻololi paha i ka mea ʻike kūlana throttle.
  • Hoʻoponopono a hoʻololi paha i nā mea hoʻohui.
  • Hoʻoponopono a hoʻololi paha i nā mea uea uila hewa.

ʻAʻole ʻōlelo ʻia ka hoʻokele me ka helu kuhi hewa P0121, no ka mea hiki ke hoʻopilikia nui i ke kūpaʻa o ke kaʻa ma ke alanui. No kēia kumu, pono ʻoe e lawe i kāu kaʻa i ka hale hana i ka hikiwawe. Ma muli o ka paʻakikī o ka nānā ʻana, ʻaʻole hiki ke koho DIY i ka hale kaʻa home.

He mea paʻakikī ke koho i nā kumukūʻai e hiki mai ana, no ka mea, hilinaʻi ka nui i nā hopena o nā diagnostics i hana ʻia e ka mīkini. ʻO ka maʻamau, ʻo ke kumukūʻai no ka hoʻoponopono ʻana i kahi kino throttle i kahi hale hana hiki ke ʻoi aku ma mua o 300 euros.
