P2120 Throttle Position Sensor / Switch C Kaapuni Hana

P2120 Throttle Position Sensor / Switch C Kaapuni Hana

Papa Kuhikuhi DTC OBD-II

Ka hana kūpono ʻole o ke kaulahao o ke kiʻiona o ke kūlana o ka pahu kupu / pedal / switch "D"

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.

ʻO TPS (Throttle Position Sensor) kahi potentiometer i kau ʻia ma ke kino throttle. Hoʻoholo ia i ke kihi throttle. Ke neʻe nei ka throttle, hoʻouna ka TPS i kahi hōʻailona i ka PCM (Powertrain Control Module). ʻO ka maʻamau he 5-wire sensor: XNUMXV kuhikuhi mai PCM a i TPS, lepo mai PCM a i TPS, a me ka hōʻailona hoʻi mai TPS a i PCM.

Hoʻouna ka TPS i ka ʻike kūlana throttle i ka PCM ma luna o kēia uea hōʻailona. Ke pani ʻia ka throttle, aia ma kahi o 45 volts ka hōʻailona. Me WOT (Wide Open Throttle), hoʻokokoke ke anakahi uila TPS i ka 5 volts piha. Keʻike ka PCM i kahi uila ma waho o ka pae hana maʻamau, hoʻonoho ʻia ʻo P2120. ʻO ka leka "D" e pili ana i kahi kaapuni kikoʻī, mea ʻike, a i ʻole kahi o kahi kaapuni kikoʻī.

MEA KAHAKAHA: Ua ʻike ka PCM i kekahi loli nui i ke kūlana throttle ʻo ia ka hoʻololi kūlike i ka pihi manifold (MAP). Ma kekahi mau hiʻohiʻona, e nānā ʻo PCM iā MAP a me TPS no ka hoʻohālikelike ʻana. ʻO ke kumu kēia inā ʻike ka PCM i kahi pākēneka nui e hoʻololi i ke kūlana throttle, manaʻo ia e ʻike i kahi hoʻololi kūlike i ka pihi manifold a me ka ʻaoʻao ʻē aʻe. Inā ʻaʻole ʻo ia e ʻike i kēia hoʻololi hoʻohālikelike, hiki ke hoʻonohonoho ʻia ʻo P2120. ʻAʻole pili kēia i nā hiʻohiʻona āpau.

nā hōʻailona

Nā hōʻailona kūpono e pili pū me:

• MIL Hoʻomālamalama (Hōʻike Manaʻo)
• Pāleʻa a i ʻole misfire alanui
• ʻOno maikaʻi ʻole
• Mai moloā
• Hoʻomaka a kūlia paha

kumu

Nā kumu kūpono o ke code P2120 me:

• Kūhiʻi hoʻi ka pūpū throttle
• Ka popopo ma ka MAP a i ʻole ka pūnaewele TPS
• ʻO ke kāʻei hoʻohuli kūpono ʻole e hoʻoʻauheʻe ai
• TPS maikaʻi ʻole
• PCM maikaʻi ʻole

Nā hāʻina hiki

Inā hiki iā ʻoe ke komo i kahi mea hana scan, e nānā i ka uila ʻo TPS me KOEO (Kī ʻOihana Off Engine). Me ka throttle pani, ka uila e pili ana i 45 V. E piʻi mālie i kahi o 4.5-5 volts ke kīkiʻi ʻoe i ka throttle. I kekahi manawa, hiki i ka oscilloscope ke hopu i nā kui uila uila o ka hōʻailona TPS. Inā ʻoe e ʻike i kahi kūleʻa ʻole o ka uila kahili TPS, e hoʻololi i ka TPS.

HOOLAHA. Pono kekahi mau mea ʻike TPS e hoʻoponopono maikaʻi. Inā ʻaʻole ʻoluʻolu ʻoe e hoʻohana i ka DVOM (Digital Volt Ohmmeter) e hoʻonohonoho i kāu TPS hou, ʻo kāu koho maikaʻi loa ʻo ka lawe ʻana i kāu kaʻa i kahi hale kūʻai. Inā ʻaʻole 45V (+ a i ʻole -3V a i ʻole) ka volta me ka pani ʻana o ka throttle, a i ʻole paʻa ka heluhelu ʻana, e kāpae i ka mea hoʻohui TPS. Me ka hoʻohana ʻana iā KOEO, e nānā i kahi kuhikuhi 5V ma ka mea hoʻohui a me kahi kahua maikaʻi. Hiki iā ʻoe ke hoʻāʻo i ke kaapuni hōʻailona ma ka neʻe ʻana i kahi uwea fusible ma waena o ke kaapuni honua o ka mea hoʻohui TPS a me ke kaapuni hōʻailona. Inā heluhelu ka TPS ma ka mea hana scan i kēia manawa i ka zero, e hoʻololi i ka TPS. Eia nō naʻe, inā ʻaʻole e hoʻololi kēia i ka heluhelu ʻana i ka zero, e nānā i ka wehe a pōkole paha i ka uea hōʻailona, ​​a inā ʻaʻohe mea i loaʻa, e kānalua i kahi PCM maikaʻi ʻole. Inā hoʻololi ka hana ʻole o ka TPS i ka hana ʻole, a laila manaʻo ʻoe he hewa ka TPS.

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 kāu code p2120?

Inā makemake ʻoe i kōkua me DTC P2120, 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.
