throttle sensor kulephera

throttle sensor kulephera kumayambitsa ntchito yosakhazikika ya injini yoyaka mkati mwagalimoto. Kuti TPS sikugwira ntchito molondola tingamvetse zizindikiro zotsatirazi: osakhazikika opanda pake, kuchepa mphamvu ya galimoto, kuchuluka mafuta ndi mavuto ena ofanana. chizindikiro chachikulu kuti throttle position sensor ndi yolakwika ndi revving. Ndipo chifukwa chachikulu cha izi ndi kuvala kwa njira zolumikizirana ndi sensor valve throttle. Komabe, pali ena angapo.

Kuyang'ana throttle position sensor ndikosavuta, ndipo ngakhale woyendetsa novice amatha kuchita. Zomwe mukufunikira ndi multimeter yamagetsi yomwe imatha kuyeza voteji ya DC. Ngati sensa ikulephera, nthawi zambiri sizingatheke kuikonza, ndipo chipangizochi chimangosinthidwa ndi chatsopano.

Zizindikiro za Sensor Yosweka ya Throttle Position

Musanayambe kufotokozera zizindikiro za kuwonongeka kwa TPS, ndi bwino kuganizira mwachidule funso la zomwe throttle position sensor imakhudza. muyenera kumvetsetsa kuti ntchito yayikulu ya sensa iyi ndikuzindikira mbali yomwe damper imatembenuzidwira. Nthawi yoyatsira, kugwiritsa ntchito mafuta, mphamvu ya injini yoyaka mkati, ndi mawonekedwe agalimoto amadalira izi. Chidziwitso chochokera ku sensa chimalowa mu gawo lamagetsi la ICE, ndipo pamaziko ake kompyuta imatumiza malamulo okhudza kuchuluka kwamafuta omwe amaperekedwa, nthawi yoyatsira, yomwe imathandizira kupanga kusakaniza koyenera kwamafuta a mpweya.

Chifukwa chake, kuwonongeka kwa throttle position sensor kumawonetsedwa ndi zizindikiro zakunja izi:

• Kusakhazikika, "kuyandama", liwiro lopanda ntchito.
• Injini yoyatsira mkati imayimitsidwa panthawi yosinthira giya, kapena mutasintha kuchokera ku zida zilizonse kupita ku liwiro losalowerera ndale.
• Injini imatha kuyimitsidwa mwachisawawa pamene ikugwira ntchito.
• Poyendetsa galimoto, pali "dips" ndi jerks, mwachitsanzo, panthawi yothamanga.
• Mphamvu ya injini yoyaka mkati imachepetsedwa, mawonekedwe agalimoto akugwa. Zomwe zimawonekera kwambiri potengera mathamangitsidwe, zovuta poyendetsa galimoto kukwera, ndi / kapena ikadzaza kwambiri kapena kukokera ngolo.
• Chenjezo la Check Engine pagawo la chida limabwera (kuyatsa). Mukasanthula zolakwika kuchokera ku kukumbukira kwa ECU, chida chowunikira chikuwonetsa cholakwika p0120 kapena china cholumikizidwa ndi sensa ya throttle position ndikuchiphwanya.
• Nthawi zina, pamakhala kuchuluka kwamafuta m'galimoto.

Ndikoyeneranso kudziwa kuti zizindikiro zomwe zatchulidwa pamwambapa zingasonyezenso mavuto ndi zigawo zina za injini zoyaka mkati, zomwe ndi kulephera kwa valve throttle. Komabe, popanga diagnostics, ndikofunikira kuyang'ana kachipangizo ka TPS.

Zifukwa za kulephera kwa TPS

Pali mitundu iwiri ya masensa throttle position - kukhudzana (filimu-resistive) ndi osalumikizana (magnetoresistive). Nthawi zambiri, masensa olumikizana amalephera. Ntchito yawo imachokera pakuyenda kwa slider yapadera pamayendedwe otsutsa. Pakapita nthawi, amatopa, ndichifukwa chake sensa imayamba kupereka chidziwitso cholakwika pakompyuta. Choncho, Zifukwa za kulephera kwa sensa-resistive sensor atha kukhala:

• Kutaya kukhudza pa slider. Izi zitha kuchitika chifukwa cha kung'ambika kwake, kapena ndi chidutswa cha nsonga. Wosanjikiza wosanjikiza amatha kutha, chifukwa chomwe kulumikizana kwamagetsi kumathanso.
• Mphamvu yamagetsi pamtundu wa sensor sichimawonjezeka. Izi zitha kuchitika chifukwa chakuti zokutira m'munsi zafufutidwa pafupifupi m'munsi pamalo pomwe slider imayamba kusuntha.
• Kuvala zida za slider.
• Kuthyoka kwa mawaya a sensor. Zitha kukhala mawaya amphamvu ndi ma sign.
• Kupezeka kwa kagawo kakang'ono mumagetsi ndi / kapena chizindikiro cha sensor throttle position.

chokhudza magnetoresistive sensors, ndiye kuti alibe deposition kuchokera resistive njanji, kotero zosweka ake amachepetsedwa makamaka kuti kuthyoka kwa mawaya kapena kuchitika kwa dera lalifupi mumayendedwe awo. Ndipo njira zotsimikizira za mtundu umodzi ndi wina wa masensa ndizofanana.

Zikhale momwemo, kukonza sensa yolephera sikungatheke, kotero mutatha kufufuza, muyenera kungosintha ndi yatsopano. Pankhaniyi, ndikofunikira kugwiritsa ntchito sensa yosalumikizana ndi throttle position, popeza msonkhano woterewu umakhala ndi moyo wautali wautumiki, ngakhale ndi wokwera mtengo.

Momwe mungadziwire sensor yosweka

Kuyang'ana TPS palokha ndikosavuta, ndipo zomwe mungafune ndi ma multimeter apakompyuta omwe amatha kuyeza voteji ya DC. Chifukwa chake, kuti muwone kuwonongeka kwa TPS, muyenera kutsatira algorithm ili pansipa:

• Yatsani poyatsira galimoto.
• Lumikizani chip kuchokera pazolumikizana ndi sensor ndikugwiritsa ntchito multimeter kuti muwonetsetse kuti mphamvu ikubwera ku sensa. Ngati pali mphamvu, pitilizani kuyang'ana. Kupanda kutero, muyenera "kutulutsa" mawaya operekera kuti mupeze malo opumira kapena chifukwa china chomwe voteji ku sensa sikuyenera.
• Khazikitsani kafukufuku woyipa wa ma multimeter kuti atsike, ndi kafukufuku wabwino pakukhudzana ndi sensa, komwe chidziwitso chimapita kugawo lamagetsi.
• Pamene damper yatsekedwa (ikufanana ndi chopondapo chotsitsimula kwambiri), mphamvu yamagetsi pamtundu wa sensa sayenera kupitirira 0,7 Volts. Ngati mutsegula chowongolera (finyani kwathunthu chowongolera), ndiye kuti mtengo wofananira uyenera kukhala osachepera 4 volts.
• ndiye muyenera kutsegula pamanja damper (tembenuzani gawo) ndikuwunikanso kuwerengera kwa multimeter. Ayenera kukwera pang'onopang'ono. Ngati mtengo wofananira ukukwera mwadzidzidzi, izi zikuwonetsa kuti pali malo osokonekera mumayendedwe otsutsa, ndipo sensa yotere iyenera kusinthidwa ndi ina.

Eni ake a VAZs zoweta nthawi zambiri amakumana ndi vuto la kusweka kwa TPS chifukwa cha makhalidwe oipa mawaya (ndiko kutchinjiriza awo), amene mulingo okonzeka ndi magalimoto amenewa fakitale. Choncho, tikulimbikitsidwa kuti m'malo mwawo ndi abwino, mwachitsanzo, opangidwa ndi CJSC PES/SKK.

Ndipo, zowona, muyenera kuyang'ana ndi chida chowunikira cha OBDII. Chojambulira chodziwika bwino chomwe chimathandizira magalimoto ambiri ndi Jambulani Chida Pro Black Edition. Zidzakuthandizani kudziwa molondola nambala yolakwika ndikuwona magawo a throttle, komanso kudziwa ngati galimoto ilinso ndi mavuto, mwina mu machitidwe ena.

Zizindikiro zolakwika 2135 ndi 0223

Cholakwika chofala kwambiri chokhudzana ndi sensa ya throttle position ili ndi code P0120 ndipo imayimira "kusweka kwa sensor / switch "A" throttle position / pedal". Cholakwika china chotheka p2135 chimatchedwa "Mismatch mu kuwerenga kwa masensa No. 1 ndi No. 2 of the throttle position." Zizindikiro zotsatirazi zingasonyezenso ntchito yolakwika ya DZ kapena sensa yake: P0120, P0122, P0123, P0220, P0223, P0222. Pambuyo posintha sensayo ndi yatsopano, ndikofunikira kufafaniza zolakwikazo pamakumbukiro apakompyuta.

Scan Tool Pro imagwira ntchito ndi mapulogalamu akuluakulu a matenda a Windows, iOS ndi Android kudzera pa Bluetooth kapena Wi-Fi. Adaputala yotere yaku Korea yokhala ndi 32-bit v 1.5 chip, osati ya China 8-bit, idzalolanso osati kungowerenga ndikukhazikitsanso zolakwika kuchokera pamakumbukidwe apakompyuta, komanso kuyang'anira magwiridwe antchito a TPS ndi masensa ena. mu gearbox, kufala kapena machitidwe othandizira ABS, ESP, etc.

Mu ntchito yowunikira, scanner idzapereka mwayi wowona deta yomwe imachokera ku sensa mu nthawi yeniyeni ya robots. Mukasuntha damper, muyenera kuyang'ana zowerengera mu volts ndi kuchuluka kwa kutsegulidwa kwake. Ngati damper ili bwino, sensa iyenera kupereka zinthu zosalala (popanda kulumpha) kuchokera pa 03 mpaka 4,7V kapena 0 - 100% ndi chotchinga chotsekedwa kapena chotseguka. Ndikosavuta kwambiri kuwona ntchito za TPS muzithunzi. Dips zakuthwa zidzawonetsa kuvala kwa wosanjikiza wosanjikiza pama track a sensor.

Pomaliza

kulephera kwa throttle position sensor - kulephera sikofunikira, koma kumafunika kuzindikiridwa ndikukhazikitsidwa posachedwa. Apo ayi, injini yoyaka mkati idzagwira ntchito pansi pa katundu wochuluka, zomwe zidzachititsa kuti kuchepetsa mphamvu zake zonse. Nthawi zambiri, TPS imalephera chifukwa chakuvala ndikung'ambika ndipo sikungabwezeretsedwe. Choncho, zimangofunika kusinthidwa ndi zatsopano.
