P0343 Camshaft Position Sensor "A" Circuit Low

Khodi Yovuta ya OBD-II - P0343 - Kufotokozera Zaukadaulo

Camshaft position sensor A circuit high input (banki 1).

DTC P0343 imagwirizana ndi nthawi yagalimoto yagalimoto ndi sensa ya camshaft, yomwe imayang'anira kuzungulira kwa camshaft kutumiza deta ku kompyuta ya injiniyo kuti iwerengere kuchuluka kwamafuta ndi kuyatsa koyenera.

Kodi vuto la P0343 limatanthauza chiyani?

Iyi ndi generic Transmission Diagnostic Trouble Code (DTC), zomwe zikutanthauza kuti imakhudza mitundu yonse yazopanga / mitundu kuyambira 2003 mpaka mtsogolo.

Malamulowa akuwoneka kuti akupezeka kwambiri pagalimoto za VW, Kia, Hyundai, Chevrolet, Toyota, ndi Ford, koma zimatha kukhudza magalimoto amtundu uliwonse. Njira zothetsera mavuto zimasiyana pagalimoto ndi galimoto.

Magalimotowa amatha kukhala ndi camshaft imodzi mu block kapena imodzi (SOHC) kapena awiri (DOHC) camshafts, koma code iyi imasamala kuti palibe chothandizira kuchokera ku camshaft position sensor (s) kuchokera ku banki 1, nthawi zambiri kuyambitsa injini. Uku ndikulephera kuzungulira kwamagetsi. Bank #1 ndiye chipika cha injini chomwe chimakhala ndi silinda # 1.

PCM imagwiritsa ntchito camshaft position sensor kuti izidziwe pomwe siginolo ya crankshaft ndiyolondola, pomwe chizindikiro cha crankshaft position sensor chimalumikizidwa ndi silinda # 1 yanthawi yake, ndipo imagwiritsidwanso ntchito kulumikizitsa jekeseni wamafuta / oyambitsa jekeseni.

Ma code P0340 kapena P0341 amathanso kupezeka nthawi imodzimodzi ndi P0343. Kusiyana kokha pakati pa ma code atatuwa ndikuti vuto limatenga nthawi yayitali bwanji komanso mtundu wamavuto amagetsi omwe sensa / woyendetsa / woyendetsa magalimoto akukumana nawo. Njira zothetsera mavuto zimatha kusiyanasiyana kutengera wopanga, mtundu wa camshaft position sensor ndi mitundu yamawaya.

Zizindikiro

Popeza cholakwika cha camshaft position sensor sensor imapangitsa injini kutulutsa mafuta olakwika ndi/kapena spark, nambala ya P0343 ikhoza kuchitika pakayendetsedwe molakwika. Nthawi zambiri, khodi imatsogolera kuzinthu zotseguka, zosakhazikika, zakufa, kapena zosagwirizana.

Zizindikiro za chikhombo cha injini ya P0343 zitha kuphatikizira izi:

• Chongani chizindikiro cha injini ya
• Kugwedeza kapena kuphulika
• Amachoka, koma akhoza kuyambiranso ngati vuto silikugwirizana.
• Mutha kugwira ntchito bwino mpaka kuyambiranso; ndiye osayambiranso

Zomwe zimayambitsa zolakwika З0343

Nthawi zambiri sensa ya camshaft imayipitsidwa ndi mafuta kapena chinyezi, zomwe zimapangitsa kuti nthaka ikhale yosauka kapena voteji mu waya wamawu. Komabe, zifukwa zina zomwe zingakhalepo ndi izi:

• Sensor yolakwika ya camshaft position
• Mawaya apansi olakwika
• Kuwonongeka kwa waya
• Sitata yolakwika
• Batire yofooka kapena yakufa
• Kompyuta yolakwika ya injini
• Tsegulani mozungulira mpaka pa camshaft position sensor
• Tsegulani mu dera lazizindikiro pakati pa camshaft position sensor ndi PCM
• Kufupika kwa 5 V pakazunguliro ka camshaft position sensor
• Nthawi zina sensor ya camshaft imakhala yolakwika - dera lalifupi lamkati mpaka voteji

Njira zowunikira ndikukonzanso

Poyambira bwino nthawi zonse mumapeza Technical Service Bulletin (TSB) pagalimoto yanu. Wopanga magalimoto atha kukhala ndi memory memory / PCM reprogramming kuti athetse vutoli, ndipo ndibwino kuti muziyese musanapite patali / molakwika.

Kenako pezani ma camshaft ndi crankshaft position sensors pagalimoto yanu. Popeza amagawana magetsi ndi ma circuits apansi, ndipo nambala iyi imayang'ana kwambiri pamagetsi ndi maunda apansi a sensa ya CMP, ndizomveka kuwayesa kuti awone ngati pali zowononga zilizonse.

Chitsanzo cha chithunzi cha sensa ya camshaft (CMP):

Mukazindikira, yang'anani zowonera zolumikizira ndi zingwe. Sakani scuffs, scuffs, mawaya owonekera, zopsereza, kapena pulasitiki wosungunuka. Chotsani zolumikizira ndikuyang'anitsitsa malo (zitsulo) mkati mwa zolumikizira. Onani ngati akuwoneka olunda, owotcha, kapena obiriwira poyerekeza ndi mtundu wachitsulo womwe mumakonda kuwawona. Ngati pakufunika kuyeretsa kosachiritsika, mutha kugula zotsukira zamagetsi pamalo aliwonse ogulitsa. Ngati izi sizingatheke, pezani 91% akusisita mowa ndi burashi ya pulasitiki yoyera kuti muyeretsedwe. Kenako awumitseni kuti awume, atenge dielectric silicone pawiri (zomwezi zomwe amagwiritsa ntchito popangira mababu ndi ma waya amagetsi) ndikuyika malo omwe amalumikizirana.

Ngati muli ndi chida chosakira, chotsani ma code azovuta zakumbukiro ndikuwona ngati nambala yanu ibwerera. Ngati sizili choncho, ndiye kuti mwina pali vuto lolumikizana.

Khodi ikabwerera, tifunika kuyesa sensa ndi ma circuits ena. Nthawi zambiri pamakhala mitundu iwiri ya masensa oyimira camshaft: Mphamvu yamaholo kapena maginito. Nthawi zambiri mumatha kudziwa kuti ndi iti yomwe muli nayo ndi nambala ya mawaya ochokera ku sensa. Ngati pali mawaya atatu ochokera ku sensa, iyi ndi sensor ya Hall. Ngati ili ndi mawaya awiri, ikhala chojambula cha maginito.

Khodi iyi imangokhazikitsidwa ngati sensa ndi chojambulira cha Hall effect. Chotsani zingwe kuchokera ku sensa ya CMP. Gwiritsani ntchito digito volt ohmmeter (DVOM) kuti muwone magetsi oyendera 5V akupita ku sensa kuti muwonetsetse kuti ilipo (waya wofiira kupita kudera lamagetsi la 5V / 12V, waya wakuda pamalo abwino). Gwiritsani ntchito chithunzi cha waya kapena tebulo lodziwitsa kuti muwone ngati sensa iyi ili ndi ma volts 5 kapena 12. Ngati sensa ili ndi volts 12 ikafika volts 5, konzani waya kuchokera ku PCM kupita ku sensa kwa ma volts ochepa mpaka 12 kapena mwina PCM yolakwika.

Ngati izi si zachilendo, ndi DVOM, onetsetsani kuti muli ndi 5V pamagetsi a CMP (waya wofiira kupita kumalo ozungulira masensa, waya wakuda kupita kumalo abwino). Ngati palibe ma volts 5 pa sensa, kapena ngati muwona ma volts 12 pa sensa, konzani waya kuchokera ku PCM kupita ku sensa, kapena kachiwiri, mwina PCM yolakwika.

Ngati zonse zili bwino, onetsetsani kuti sensa iliyonse ili pansi. Lumikizani nyali yoyeserera ku batri ya 12 V (malo ofiira ofiira) ndikukhudza kumapeto kwina kwa nyali yoyeserera yoyenda pansi yomwe imatsogolera ku camshaft sensor ground ground. Ngati nyali yoyesera sakuwala, imawonetsa dera lolakwika. Ngati ikuwunika, sinthani zingwe zama waya kupita ku sensa iliyonse kuti muwone ngati nyali yoyeserera ikuwala, kuwonetsa kulumikizana kwapakatikati.

ZOPHUNZITSA ZAMBIRI PAMENE AMADZIWA KODI P0343

Cholakwika chofala kwambiri pochita ndi bwalo la P0343 ndi kuzungulira zolakwika zosinthira. Ndikofunikira kugwiritsa ntchito zida zosinthira zapamwamba ndikupewa zotsika mtengo kapena zogwiritsidwa ntchito. Popeza masensa ena amakhalanso kupanikizana chifukwa cha kutayikira kwamafuta, ndikwabwino kukonza zotuluka zapafupi kuti vutoli lisapitirire.

KODI P0343 NDI YOYAMBA BWANJI?

Popeza camshaft position sensor ndiyofunika kwambiri jekeseni wamafuta m'galimoto yamakono, nambala ya P0343 ingakhudze kwambiri momwe galimoto imayendetsedwera. Ndikoyenera kutchula code iyi mwamsanga.

KODI KUKONZA KODI KUUNGAKONZE KODI P0343)?

Kukonza kofala kwa P0343 kuli motere:

• Kusintha malo a camshaft sensor
• Kusintha zingwe zowonongeka ndi zolumikizira
• Kuyeretsa pansi mawaya
• Konzani kutayikira mafuta pafupi

ZOWONJEZERA ZOWONJEZERA KUDZIWA KODI P0343

Ma Code P0343 amawonekera pamitundu ya Chevrolet, Kia, Volkswagen ndi Hyundai - nthawi zambiri amatsanzira kuyambira 2003 mpaka 2005. Si zachilendonso kuti nambala ya P0343 ipangitse ma code ena ovuta.

Mukufuna thandizo lina ndi nambala yanu ya p0343?

Ngati mukufunabe thandizo ndi DTC P0343, lembani funso mu ndemanga pansipa pamutuwu.

ZINDIKIRANI. Izi zimaperekedwa kuti zidziwitse zokha. Sikuti tizigwiritsa ntchito ngati malingaliro okonzanso ndipo sitili ndi udindo pazomwe mungachite pagalimoto iliyonse. Zomwe zili patsamba lino ndizotetezedwa ndi zovomerezeka.
