P2123 Throttle Position Sensor / Switch D Circuit Hoʻokomo kiʻekiʻe

Papa Kuhikuhi DTC OBD-II

Throttle / Pedal Position Sensor / Switch «D» Kaapuni kiʻekiʻe hoʻokomo

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.

I koʻu hālāwai ʻana me kahi pāʻālua P2123 i mālama ʻia, ua ʻike wau ʻo ia ka mana o ka module powertrain control (PCM) i ʻike i kahi hoʻokomo uila kiʻekiʻe mai ke kaapuni kūlana throttle (TPS) a i ʻole ke kaapuni pākana pedal (PPS) kaapuni. ʻO ka «D» e pili ana i kekahi kaapuni kikoʻī, kekona, a i ʻole ʻāpana o kahi kaapuni kikoʻī.

E nīnau i kahi kumu hilinaʻi o ka ʻike kaʻa (e holo pono nā ʻike DIY āpau) no nā kikoʻī o ke kaʻa e nīnau ʻia ana. Hoʻohana wale ʻia kēia pāʻālua i nā kaʻa i lako me nā ʻōnaehana drive-by-wire (DBW).

Mālama ka PCM i ka ʻōnaehana DBW me ka hoʻohana ʻana i ka moto actuator motor, hoʻokahi a ʻoi paha nā mīkini uila (a i kapa ʻia kekahi mau manawa nā ʻenekini hoʻokele wikiwiki. Loaʻa nā uila i nā uila uila (maʻamau 5 V) a me ka honua. ʻO ka hapa nui o nā sensor TPS / PPS o ka potentiometer ʻano a hoʻopau i ke kaapuni kūpono. Hoʻonui ʻia kahi axle pivoting ma ka pedal wikiwiki a i ʻole ka lāʻau throttle e hoʻoliʻiliʻi i nā pilina o ke aniani. Hoʻololi ke kūʻē Sensor i ka neʻe ʻana o nā mākia ma o ka PCB mīkiniʻimi, e hoʻololi ana i ka pale kaapuni a me ka uila komo i ka PCM.

Inā ʻoi aku ka voltage hōʻailona hoʻokomo i ka palena o ka papahana, no kahi manawa lōʻihi a ma lalo o kekahi mau kūlana, e mālama ʻia ka code P2123 a hoʻomālamalama ʻia ka Lamp Indikator Malfunction (MIL).

Nā ʻōuli / koʻikoʻi

Ke mālama ʻia kēia pāʻālua, komo ka PCM i ka ʻano ʻoʻopa. I kēia ʻano, e kaupalena ʻia ka hoʻoneʻe ʻana o ka ʻenekini (inā ʻaʻohe kīnā). Pākuʻi ʻia paha nā ʻōuli o kahi pāʻālua P2123:

• Paʻa ka throttle (i nā rpm a pau)
• Kaupalena ʻaʻano ʻAʻohe hoʻoholomua
• Kū ka ʻenekini ke noho palaka
• Oscillation ma ka wikiwiki
• ʻAʻole holo ka Cruise control

kumu

ʻO nā kumu kūpono o kēia code engine me:

• E wehe a i ʻole ke kaapuni pokole i kahi kaulahao ma waena o TPS, PPS a me PCM
• TPS hemahema a i ʻole PPS
• Pākuʻi uila uila
• Mīkini hoʻokaʻawale hoʻokele mamao kīnā

Nā diagnostics a me nā kaʻina hana hoʻoponopono

ʻO kahi wahi hoʻomaka maikaʻi ke nānā mau nei i ka Bulletins Service Technical (TSB) no kāu kaʻa ponoʻī. ʻO kou pilikia he pilikia i ʻike ʻia me kahi mea hana i hoʻokuʻu ʻia a hoʻokuʻu ʻia hiki ke mālama iā ʻoe i ka manawa a me ke kālā i ka wā o nā diagnostics.

E kiʻi wau i kahi scanner diagnostics, volt / ohmmeter digital (DVOM), a me kahi ʻike ʻike kaʻa e like me All Data (DIY) e kuhikuhi i ka pāʻālua P2123.

E lawe wau i ka hana mua o kaʻu kuhi ma ka nānā ʻana i nā pilina āpau a me nā pilina e pili ana i ka ʻōnaehana. Makemake pū kekahi wau e nānā i ke kino throttle no nā hōʻailona o ke kūkulu ʻana o carbon a i ʻole nā ​​pohō. ʻO ke kūkulu kalapona nui ʻana e mālama i ka wehe o ke kino throttle i ka hoʻomaka ʻana e hopena paha i kahi pāʻālua P2123 e mālama ʻia. E hoʻomaʻemaʻe i nā waihona kalapona mai ke kino throttle e like me nā ʻōlelo a ka mea hana a hoʻoponopono a hoʻololi paha i nā uea hewa a i ʻole nā ​​ʻāpana e pono ai, a laila ho'āʻo hou i ka ʻōnaehana DBW.

A laila hoʻohui wau i ka scanner i ke awa diagnostic kaʻa a lawe mai i nā DTC i mālama ʻia. Kākau wau i lalo inā pono wau i ke kauoha kahi i mālama ʻia ai nā pāʻālua. Makemake pū kekahi wau e mālama i kekahi ʻikepili pili manu paʻa. Hiki ke kōkua i kēia mau memo inā lilo ʻo P2123 i intermittent. I kēia manawa ke hoʻomaʻemaʻe nei wau i nā code a hoʻāʻo e hoʻokele i ke kaʻa. Inā hoʻomaʻemaʻe ke code, hoʻomau wau i ka diagnose

Hiki ke ʻike ʻia nā piʻi a me nā mismatches ma waena o TPS, PPS a me PCM me ka hoʻohana ʻana i ka kahawai ʻikepili scanner. Hoʻopili i kāu kahawai ʻikepili e hōʻike i nā ʻikepili pili wale no ka pane wikiwiki. Inā ʻaʻole i loaʻa nā kuʻikuʻi a me / a i ʻole inconsistencies, e hoʻohana i ka DVOM e kiʻi i ka ʻikepili manawa maoli mai kēlā me kēia sensor. No ka loaʻa ʻana o ka ʻikepili manawa maoli me ka hoʻohana ʻana i ka DVOM, hoʻohui i nā hoʻokolohua i nā hōʻailona kūpono a me nā kaapuni honua a nānā i ka hōʻike DVOM ʻoiai e holo ana ka DBW. Nānā i nā nalu uila ke neʻe lohi nei i ka valve throttle mai ka paʻa a wehe loa. ʻO ke anakahi uila mai 5V i hoʻopaʻa i ka throttle i ka 4.5V ākea ākea. Inā loaʻa nā piʻi a i ʻole nā ​​mea ʻē aʻe ʻē aʻe, e manaʻo ʻoe he hewa ʻole ka mea ʻike ʻia. ʻO kahi oscilloscope kahi mea hana pono no ka hōʻoia ʻana i ka hana o nā mea ʻike.

Nā memo diagnostical hou aʻe:

• Pono kekahi mau mea hana i ke kino throttle, motor throttle actuator, a me nā sensors kūlana throttle āpau e pani pū ʻia.

Nā kūkākūkā DTC e pili ana

• Nā ʻōkuhi OBD P2123 a me P2128 ma Audi A4 B6 Quattro 1.8TUa pilikia ʻo Audi A4 B6 Quattro 1.8T me ka pā radiator, ua haʻi ʻia wau e hemo i ka uea sensor ma ke kaukini radiator o lalo a lele e ʻike inā hele mai ka peahi, akā ʻaʻole. Ma hope o kēlā, ʻaʻohe throttle ke hoʻomaka nei i ka throttle. inā kāomi wau i ka hehi wāwae, ʻaʻohe mea i loaʻa, e kiʻi i kēia mau code ʻelua P2123 P2123 ... 
• ʻO Mercedes Vito Code p2123Ke hoʻokele nei wau i kaʻu Mercedes vito i nā revs kiʻekiʻe a ʻoki koke ʻia a ʻaʻole hoʻomaka, e huli ʻia naʻe, kau i kahi diagnostic a piʻi mai ka helu hewa p2123. Ke haʻohaʻo wale nei wau inā hiki i kekahi ke hāʻawi mai iaʻu i kekahi ʻōlelo aʻoaʻo e pili ana i ka mea e hiki ai, no ka mea ke hopohopo iki nei wau ʻo ka uila paha ia. Kanaka… 

Pono i kōkua hou me kāu code p2123?

Inā makemake ʻoe i kōkua me DTC P2123, 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.
