P0643 Reference voltage sensor circuit "A" yakakwirira

P0643 - OBD-II Dambudziko Code Unyanzvi Tsananguro

Dambudziko rekodhi P0643 rinoratidza kuti voltage pa sensor referensi voltage wedunhu "A" yakawandisa (ichienzaniswa nekukosha kunotsanangurwa mune zvakatemwa nemugadziri).

Ko fault code inorevei P0643?

Dambudziko rekodhi P0643 rinoratidza kuti sensor referensi voltage wedunhu "A" yakakwira zvakanyanya kana ichienzaniswa neyakagadzirwa nemugadziri. Izvi zvinoreva kuti powertrain control module (PCM), injini yekudzora module (ECM), kana imwe mota yekuwedzera yekudzora module yakaona yakakwira zvisingaite padunhu iri. Iyo Injini Yekudzora Module (ECM) inowanzo ine matatu 5-volt referensi maseketi ayo anodyisa akasiyana masensa. Dunhu rega rega rakagadzirirwa kuti ripe referensi voltage kune chaiwo masensa. Kazhinji, dunhu "A" rine basa rekupa referensi voltage kune accelerator pedal position sensor.

Zvimwe zvinokonzera

Zvimwe zvikonzero zvinogoneka zveiyo P0643 kodhi:

• Waya yakakuvadzwa kana chinongedzo mureferensi voltage wedunhu: Kukuvadza kune waya kana zvibatanidza zvinogona kukonzera kupfupika kana kuvhurika dunhu, izvo zvinogona kukonzera yakakwira voltage.
• Sensor kusashanda zvakanaka: Kana iyo sensor inogamuchira referensi voltage kubva kudunhu "A" yakakuvadzwa kana kusashanda, inogona kukonzera abnormal high voltage mudunhu.
• Engine control module (ECM) kana powertrain control module (PCM) kusashanda: Iyo mota yekudzora module pachayo inogona kukuvara kana kusashanda zvakanaka, zvichiita kuti ibudise zvisizvo masaini emagetsi.
• Matambudziko negrounding system: Kudzika pasi kwakashata kunogonawo kukonzera kukanganisa mumagetsi ereferensi redunhu, izvo zvinogona kuita kuti kodhi P0643 ioneke.
• Jenereta kukanganisa: Kana alternator yemotokari yako ikatadza kana kuburitsa voltage yakawandisa, inogona kukonzera P0643.

Ndezvipi zviratidzo zvekodhi yemhosva? P0643?

Zvimwe zviratidzo zvinogoneka kana dambudziko kodhi P0643 iripo:

• Tarisa Injini Indicator: Kana P0643 iripo, Cheki Engine Chiedza kana MIL (Malfunction Indicator Lamp) inogona kuvhenekera padashboard yako kuratidza dambudziko.
• Kupera Simba: Panogona kuve nekuderera kana kurasikirwa kweinjini simba nekuda kwekushanda kwakashata kweiyo control system.
• Kusagadzikana kusina basa: Mota inogona kunge iine hutsinye kana kuzunguzika isingaiti nekuda kwekutadza kushanda kwemasensa kana sisitimu yekudzora.
• Mafuta emafuta asina kunaka: Kuwedzera kushandiswa kwemafuta kana kuderera kwekushanda kunogona kunge kuri nekuda kwekusashanda zvakanaka kweiyo control system.
• Kumhanya kusina kugadzikana: Matambudziko nekumhanya kweinjini anogona kuitika, sekutinhira kana shanduko mukumhanya pasina chikonzero chakajeka.

Nzira yekuongorora kodhi yemhosva P0643?

Matanho anotevera anokurudzirwa kuongorora nekugadzirisa DTC P0643:

1. Kutarisa kubatanidza uye wiring: Tarisa zvese zvinongedzo zvemagetsi zvine chekuita nesensor referensi voltage "A" sekiti, kusanganisira majoini, mapini, uye waya kune kukuvara, ngura, kana kuputsika.
2. Kuongorora kwemagetsi: Uchishandisa multimeter, kuyera voltage mudunhu "A" ye sensor referensi voltage. Ita shuwa kuti voltage inosangana nezvinodiwa nemugadziri.
3. Kuongorora ma sensors: Tarisa mamiriro uye kushanda kwema sensors anogamuchira referensi voltage kubva kudunhu "A". Ita shuwa kuti masensa haana kukuvara uye akabatana nemazvo.
4. Kuongorora Injini Yekudzora Module (ECM): Tarisa injini yekudzora module yehurema kana kusashanda. Specialized ECM yekuongorora michina inogona kudiwa.
5. Dzokorora kukanganisa: Mushure mekunyatsoongorora nekugadzirisa dambudziko, gadzirisazve kodhi yedambudziko uye tora iyo test drive kuti uone kuti dambudziko ragadziriswa.

Kana dambudziko risingazivikanwe kana kugadziriswa wega, zvinokurudzirwa kuti ubate nyanzvi yemotokari inokwanisa kana chitoro chekugadzirisa mota kuti uwedzere kuongororwa uye kugadzirisa.

Zvikanganiso zvekuongorora

Kana uchiongorora DTC P0643, zvikanganiso zvinotevera zvinogona kuitika:

• Tsanangudzo isiriyo yedata: Imwe yemhosho huru inogona kuve isiriyo dudziro ye data yakawanikwa kana uchitarisa voltage kana mamiriro eiyo wiring. Izvi zvinogona kutungamirira kusarudzo isina kururama yechikonzero chekusashanda zvakanaka.
• Kutsiviwa kwechikamu kusiri iko: Kana kuongororwa kwakakwana kusingaitwe, kune ngozi yekutsiva zvikamu zvisina kufanira. Izvi zvinogona kukonzera imwe nguva uye zviwanikwa zvichishandiswa pasina kugadzirisa dambudziko riripo.
• Kuregeredza mamwe matambudziko anogona kuitika: Nekutarisa pane rimwe dambudziko chairo, unogona kupotsa zvimwe zvinogona kukonzera kukundikana. Izvo zvakakosha kuti titarise zvese zvinogoneka zvinhu zvinokanganisa sensor voltage referensi redunhu.
• Kubatana kwe sensor isina kururama: Paunenge uchitarisa masensa, iwe unofanirwa kuve nechokwadi kuti akabatana nemazvo uye anosangana nezvinodiwa nemugadziri. Kubatana kusiri iko kunogona kutungamira kune zvisizvo zvekuongororwa mhedzisiro.
• Hardware matambudziko: Kusakwana kwakarurama kana kukanganisa maturusi ekuongorora kunogona kutungamirira kune mhedziso dzisina kururama. Izvo zvakakosha kushandisa yakavimbika uye calibrated michina yechokwadi kuongororwa.

Kuti udzivise zvikanganiso izvi, zvinokurudzirwa kuita diagnostics zvakanyatsonaka, uchitevera maitiro emugadziri uye mazano, uye, kana zvichidiwa, tsvaga rubatsiro kubva kune vane ruzivo ruzivo.

Kodhi yemhosva yakakomba zvakadii? P0643?

Dambudziko kodhi P0643 inoratidza kuti sensor referensi voltage wedunhu yakakwira zvakanyanya. Iri rinogona kuve dambudziko rakakomba rinokanganisa kushanda kweakasiyana masisitimu emotokari senge mafuta jekiseni system, ignition system nezvimwe. Kana rikasagadziriswa, dambudziko iri rinogona kukonzera kusashanda zvakanaka kweinjini, kupera simba, kushomeka kwemafuta emafuta, uye kuwedzera kuburitsa kwemhepo.

Uye zvakare, kusakwana voltage mureferensi voltage wedunhu kunogona kukonzera matambudziko neiyo injini manejimendi system uye mamwe masisitimu emotokari, izvo zvinogona kukanganisa kutyaira kuchengetedza uye kuvimbika.

Saka, kunyangwe iyi kodhi yedambudziko ingangove isiri iyo nekukasira kutsoropodza, zvakakosha kuitora zvakakomba uye kuti iongororwe uye igadziriswe nekukurumidza sezvinobvira kudzivirira zvimwe zvakakomba mhedzisiro.

Chii kugadzirisa kuchabatsira kubvisa kodhi? P0643?

Kugadzirisa DTC P0643, tevera matanho aya:

1. Kuedza Reference Voltage Circuit: Chekutanga, tarisa referensi voltage redunhu yekapfupi kana kuvhura. Izvi zvinogona kuitwa uchishandisa multimeter nekuyera voltage pamapini ekubatanidza anoenderana.
2. Kutarisa iyo Accelerator Pedal Sensors uye Sensors: Tarisa ma sensors anofambiswa nereferensi voltage wedunhu, senge accelerator pedal chinzvimbo sensor. Ita shuwa kuti vari kushanda nemazvo uye vane voltage chaiyo.
3. Ongorora Wiring uye Zviunganidzi: Tarisa wiring uye majoini kune kukuvara, ngura, kana kutadza kuonana. Gadzirisa kana kutsiva zvikamu zvakakuvadzwa.
4. Kutsiva iyo PCM/ECM: Kana ese ari pamusoro apa nhanho akasagadzirisa dambudziko, iyo PCM/ECM pachayo inogona kunge isina kukanganisa. Muchiitiko ichi, kutsiva kana kugadzirisazve injini yekudzora module inodiwa.
5. Mamwe matanho ekugadzirisa: Dzimwe nguva dambudziko rinogona kukonzerwa nezvimwe zvinhu, senge pfupi pfupi mune imwe mota system. Muchiitiko ichi, kuwedzera kuongororwa uye kugadzirisa kunodiwa.

Mushure mekupedza matanho aya, unofanirwa kuyedza mota kuti uone kana kukanganisa kwaitika. Kana yakaitwa nemazvo, iyo P0643 kodhi inofanirwa kugadzirisa. Kana dambudziko rikaramba riripo, zvinokurudzirwa kuti utaure nemotokari yekuongorora uye kugadzirisa nyanzvi yekuongorora kwakadzama.
