Khodi Yovuta ya OBD-II - P0638 - Kufotokozera Zaukadaulo
Mtundu Wowongolera Wowongolera / Kuchita (Bank 1)
Khodi Yovuta Yodziwitsa (DTC) ndi nambala yotumizira ya OBD-II. Imawerengedwa kuti ndiyaponseponse momwe imagwirira ntchito popanga mitundu yonse yamagalimoto (1996 ndi atsopano), ngakhale njira zowongolera zingasiyane kutengera mtunduwo.
Kodi vuto la P0638 limatanthauza chiyani?
Magalimoto ena atsopano amakhala ndi makina oyendetsa pagalimoto pomwe thupilo limayang'aniridwa ndi kachipangizo kamene kamagwiritsa ntchito gasi, gawo loyendetsa mphamvu yamagetsi / gawo lowongolera ma injini (PCM / ECM), ndi mota wamagetsi m'thupi loyenda.
PCM / ECM imagwiritsa ntchito Throttle Position Sensor (TPS) kuti iwunikire momwe imakhalira, ndipo pomwe malo akewo sakutha ndi chandamale, PCM / ECM imakhazikitsa DTC P0638. Bank 1 imanena za mbali imodzi yamphamvu ya injini, komabe magalimoto ambiri amagwiritsa ntchito thupi limodzi lopindika pazitsulo zonse. Khodi iyi ndiyofanana ndi P0639.
Ambiri a valavu yamagulugufe amtunduwu sangathe kukonzedwa ndipo ayenera kusinthidwa. Thupi lakutambasula limapangidwa ndi kasupe kuti likhale lotseguka ngati injini ikulephera, nthawi zina thupi loyenda silimayankha ndikulephera kwathunthu ndipo galimoto imangoyendetsa pang'onopang'ono.
Zindikirani. Ngati pali ma Throttle Position Sensor DTCs, onetsetsani kuti mukuwongolera musanazindikire nambala ya P0638.
Zizindikiro
Zizindikiro za vuto la P0638 zitha kuphatikiza:
- Check Engine Light (Nyali Yosazindikiritsa Yoyatsa) ndiyomwe ili
- Galimoto imatha kugwedezeka ikamathamanga
Zomwe Zingayambitse Code P0638
Zifukwa za DTC iyi zitha kuphatikiza:
- Ngoal udindo kachipangizo wonongeka
- Fulumizitsa Udindo SENSOR Kulephera
- Makina Ozungulira a Throttle Actuator
- Thupi lonyansa lonyansa
- Zingwe za waya, zotayirira kapena zolumikizana zonyansa
- Kulephera kwa PCM / ECM
Njira zowunikira / kukonza
Pedal position sensor - Sensa ya pedal position ili pa accelerator pedal. Nthawi zambiri, mawaya atatu amagwiritsidwa ntchito kudziwa malo opondaponda: chizindikiro cha 5V choperekedwa ndi PCM/ECM, nthaka, ndi chizindikiro cha sensor. Chifaniziro cha mawaya a fakitale chidzafunika kudziwa waya womwe ukugwiritsidwa ntchito. Onetsetsani kuti kulumikizako ndi kotetezeka ndipo palibe mawaya otayira mu harness. Gwiritsani ntchito digito volt-ohmmeter (DVOM) yokhazikitsidwa ku ohm sikelo kuti muyese kuyika bwino polumikiza waya umodzi pansi pa cholumikizira cha sensa ndi china ku chassis ground - kukana kuyenera kukhala kotsika kwambiri. Yesani 5 volt reference kuchokera ku PCM pogwiritsa ntchito DVOM yoyikidwa ku volts ndi waya wabwino pa cholumikizira cha harness ndi waya woipa pamalo odziwika bwino ndi kiyi pothamanga kapena pa malo.
Yang'anani mphamvu yamagetsi ndi DVOM yoyikidwa ku ma volts, ndi waya wofiyira pamalo owonetsera ndi waya wolakwika pamalo odziwika bwino ndi kiyi yothamanga / pa malo - voteji yamagetsi iyenera kuwonjezeka pamene mukukankhira gasi. Childs, voteji ranges kuchokera 0.5 V pamene pedal si maganizo kwa 4.5 V pamene throttle ndi lotseguka kwathunthu. Zingakhale zofunikira kuyang'ana mphamvu yamagetsi pa PCM kuti mudziwe ngati pali kusiyana kwa magetsi pakati pa sensa ndi zomwe PCM ikuwerenga. Chizindikiro cha encoder chiyenera kufufuzidwanso ndi graphical multimeter kapena oscilloscope kuti muwone ngati magetsi akuwonjezeka bwino popanda kutsika pamayendedwe onse. Ngati chida chojambulira chapamwamba chilipo, sensa yamalo nthawi zambiri imawonetsedwa ngati gawo lazolowera zomwe mukufuna, kutsimikizira kuti mtengo womwe mukufuna ndi wofanana ndi malo enieniwo.
Malo othamanga - Sensa ya throttle position imayang'anira malo enieni a throttle body vane. Sensa ya throttle position ili pa thupi la throttle. Nthawi zambiri, mawaya atatu amagwiritsidwa ntchito kudziwa malo opondaponda: chizindikiro cha 5V choperekedwa ndi PCM/ECM, pansi, ndi chizindikiro cha sensor. Chifaniziro cha mawaya a fakitale chidzafunika kudziwa waya womwe ukugwiritsidwa ntchito. Onetsetsani kuti kulumikizako ndi kotetezeka ndipo palibe mawaya otayira mu harness. Gwiritsani ntchito digito volt-ohmmeter (DVOM) yokhazikitsidwa ku ohm sikelo kuti muyese kuyika bwino polumikiza waya umodzi pansi pa cholumikizira cha sensa ndi china ku chassis ground - kukana kuyenera kukhala kotsika kwambiri. Yesani 5 volt reference kuchokera ku PCM pogwiritsa ntchito DVOM yoyikidwa ku volts ndi waya wabwino pa cholumikizira cha harness ndi waya woipa pamalo odziwika bwino ndi kiyi pothamanga kapena pa malo.
Yang'anani mphamvu yamagetsi ndi DVOM yoyikidwa ku ma volts, ndi waya wofiyira pamalo owonetsera ndi waya wolakwika pamalo odziwika bwino ndi kiyi yothamanga / pa malo - voteji yamagetsi iyenera kuwonjezeka pamene mukukankhira gasi. Childs, voteji ranges kuchokera 0.5 V pamene pedal si maganizo kwa 4.5 V pamene throttle ndi lotseguka kwathunthu. Zingakhale zofunikira kuyang'ana mphamvu yamagetsi pa PCM kuti mudziwe ngati pali kusiyana kwa magetsi pakati pa sensa ndi zomwe PCM ikuwerenga. Chizindikiro cha throttle position sensor chiyeneranso kufufuzidwa ndi graphical multimeter kapena oscilloscope kuti mudziwe ngati magetsi akuwonjezeka bwino popanda kusiya paulendo wonse. Ngati chida chojambulira chapamwamba chilipo, sensa yamalo nthawi zambiri imawonetsedwa ngati gawo la malo enieni a throttle, kutsimikizira kuti mtengo womwe ukufunidwa ndi wofanana ndi malo oyikapo.
Makina oyendetsa makina oyendetsa galimoto - The PCM/ECM idzatumiza chizindikiro ku throttle actuator motor kutengera malo olowera pedal ndi mtengo womwe udakonzedweratu kutengera momwe amagwirira ntchito. Malo opondapo amadziwika ngati kulowetsa komwe amafunidwa chifukwa PCM/ECM imawongolera malo opumira ndipo imatha kuchepetsa magwiridwe ake pazinthu zina. Ma motors ambiri amakhala ndi ntchito yozungulira. Yesani mota ya throttle kuti ikukane koyenera podula cholumikizira cholumikizira ndi DVOM choyikidwa pa sikelo ya ohm yokhala ndi zotsogola zabwino ndi zoyipa kumapeto konse kwa ma terminals a mota. Kukaniza kuyenera kukhala mkati mwazinthu za fakitale, ngati kuli kokwera kwambiri kapena kotsika kwambiri, galimotoyo singasunthe kumalo omwe mukufuna.
Yang'anani mawaya pofufuza mphamvu pogwiritsa ntchito chithunzi cha mawaya a fakitale kuti mupeze mawaya oyenera. Waya wamagetsi ukhoza kuyesedwa ndi DVOM yokhazikitsidwa ku volts, ndi waya wabwino pa waya wamagetsi ndi waya woipa pa nthaka yabwino yodziwika. Mphamvu yamagetsi iyenera kukhala pafupi ndi voteji ya batri yokhala ndi kiyi pothamanga kapena pamalo, ngati mphamvu yatayika kwambiri mawaya atha kukhala okayikitsa ndipo ayenera kufufuzidwa kuti adziwe komwe kutsika kwa voteji kukuchitika. Waya wamakina amakhazikitsidwa kudzera pa PCM ndipo amayatsidwa ndikuzimitsidwa ndi transistor. Kuzungulira kwa ntchito kumatha kufufuzidwa ndi graphical multimeter kapena oscilloscope yokhazikitsidwa ku ntchito yozungulira yomwe ili ndi chiwongolero chabwino cholumikizidwa ndi waya wamakina ndi njira yoyipa kupita kumalo odziwika bwino - voltmeter yokhazikika imangowonetsa voteji yapakati yomwe ingakhale yovuta dziwani ngati pali magetsi otsika pakapita nthawi. Ntchito yozungulira iyenera kufanana ndi kuchuluka kwa PCM/ECM. Zingakhale zofunikira kuyang'ana ntchito yomwe yatchulidwa kuchokera ku PCM/ECM ndi chida chapamwamba chojambula.
Thupi loyenda - Chotsani thupi la throttle ndikuyang'ana zopinga zilizonse kapena kudziunjikira kwa dothi kapena mafuta mozungulira phokoso lomwe lingasokoneze kuyenda kwanthawi zonse. Kuthamanga kodetsa kungapangitse kuti phokosolo lisayankhe bwino pamene likulamulidwa ku malo enaake ndi PCM / ECM.
Ma PCM / ECM - Pambuyo poyang'ana ntchito zina zonse pa masensa ndi injini, PCM / ECM ikhoza kuyesedwa kuti iwonetsere zomwe mukufuna, malo enieni a throttle, ndi malo omwe akuyang'ana injini pogwiritsa ntchito chida chapamwamba chojambula chomwe chidzawonetsa zolowetsa ndi zotsatira monga peresenti. Ngati zikhalidwe sizikufanana ndi manambala enieni omwe alandilidwa kuchokera ku masensa ndi mota, patha kukhala kukana kwakukulu mu waya. Mawaya amatha kufufuzidwa pochotsa chingwe cha sensa ndi PCM / ECM harness pogwiritsa ntchito DVOM yokhazikitsidwa ku ohm scale ndi waya wabwino ndi woipa pa malekezero onse a harness.
Muyenera kugwiritsa ntchito chithunzi cholumikizira fakitale kuti mupeze mawaya olondola pachinthu chilichonse. Ngati zingwe zikulimbana kwambiri, manambala omwe akuwonetsedwa ndi PCM / ECM mwina sangafanane ndi zomwe mukufuna, zotulutsa zomwe mukufuna, ndi zotulutsa zenizeni, ndipo DTC idzakhazikitsa.
