ʻO P212D Throttle Position Sensor / Switch G Input Circ High
Papa Kuhikuhi DTC OBD-II
ʻO ke kiʻekiʻe kiʻekiʻe o kahi hōʻailona hoʻokomo i loko o ke kaulahao o ke kiʻikuhi o ke kūlana o ka pahu butterfly / switch "G"
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 ʻike ʻana i kahi pāʻālua mālama P212D, ua ʻike wau ʻo ia ka mana o ka module powertrain control (PCM) i ʻike i kahi hoʻokomo uila kiʻekiʻe mai ke kaapuni ʻo Throttle Position Sensor (TPS) a i ʻole ke kaapuni Pedal Position Sensor (PPS). ʻO "G" e pili ana i kahi kaapuni kikoʻī, mea ʻike, a i ʻole kahi 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 nui o ke anakuhi uila i ka palena o ka papahana, e mālama ʻia ʻo P212D no kahi manawa lōʻihi ma lalo o kekahi mau ʻano a e hoʻomālamalama ʻia kahi Lamp Kuhi Mal mal (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 ka pāʻālua P212D:
- 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 nā kumu ʻike kaʻa e like me All Data (DIY) e kuhikuhi i ka pāʻālua P212D.
E lawe wau i ka hana mua o kaʻu kuhi ma ka nānā ʻana i nā pilina āpau a me nā hoʻopili e pili ana i ka ʻōnaehana. Makemake wau e nānā i ke kino throttle no nā ʻōuli o ke kūkulu ʻana o carbon a i ʻole nā pōʻino. 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 P212D 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 ʻoe i ke kauoha kahi i mālama ʻia ai nā pāʻālua. Makemake pū kekahi wau e mālama i kekahi ʻikepili pili manu paʻa e pili ana. Hiki ke kōkua i kēia mau memo inā ʻaʻole holo pono ka P212D. 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
- 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 ke code p212D?
Inā makemake ʻoe i kōkua e pili ana iā DTC P212D, 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.
