P0639 Throttle Actuator Control Range/Parameter B2

P0639 - OBD-II Mavuto Code Kufotokozera

Throttle Actuator Control Range/Magwiridwe (Banki 2)

Kodi cholakwika chimatanthauza chiyani P0639?

Magalimoto ena amakono ali ndi makina oyendetsa-waya omwe amaphatikizapo sensa mu accelerator pedal, powertrain / injini control module (PCM / ECM), ndi throttle actuator motor. PCM/ECM imagwiritsa ntchito throttle position sensor (TPS) kuti iwunikire komwe kuli throttle. Ngati malowa ali kunja kwa mtengo womwe watchulidwa, PCM/ECM imakhazikitsa DTC P0638.

Dziwani kuti "bank 2" amatanthauza mbali ya injini moyang'anizana ndi silinda nambala wani. Nthawi zambiri pamakhala valavu imodzi pa banki iliyonse ya masilinda. Code P0638 ikuwonetsa vuto mu gawo ili la dongosolo. Ngati zizindikiro zonse za P0638 ndi P0639 zizindikirika, zikhoza kusonyeza vuto la waya, kusowa mphamvu, kapena mavuto ndi PCM/ECM.

Ambiri mwa ma throttle valves sangathe kukonzedwa ndipo amafuna kusinthidwa. Thupi la throttle nthawi zambiri limatsegulidwa pamene injini ikulephera. Ngati valavu ya throttle ili yolakwika kwathunthu, galimotoyo imatha kuyendetsedwa pamtunda wochepa.

Ngati ma code okhudzana ndi throttle position sensor apezeka, ayenera kuwongoleredwa asanayambe kusanthula kachidindo ka P0639. Khodi iyi ikuwonetsa cholakwika mu makina owongolera ma throttle actuator mu banki 2 ya injini, yomwe nthawi zambiri ilibe silinda nambala wani. Ma module ena owongolera amathanso kuzindikira cholakwika ichi ndipo kwa iwo code idzakhala P0639.

Zotheka

Khodi yamavuto P0639 imatha kuchitika chifukwa cha zovuta ndi chowongolera chowongolera, chowongolera chokha, kapena sensa ya throttle position. Komanso, mawaya olakwika a network (CAN), kuyika pansi kosayenera, kapena mavuto okhala ndi mawaya apansi mumagawo owongolera angayambitse uthengawu. Chomwe chingakhale chotheka chingakhalenso cholakwika mu basi ya CAN.

Nthawi zambiri, code P0639 imalumikizidwa ndi:

1. Vuto liri ndi sensa ya poyambira gasi.
2. Vuto ndi sensa throttle position.
3. Kulephera kwa mota ya Throttle.
4. Zonyansa throttle thupi.
5. Mavuto a waya, kuphatikizapo malumikizidwe omwe angakhale akuda kapena otayirira.
6. PCM/ECM (module yowongolera injini) ikusokonekera.

Ngati nambala ya P0639 ichitika, kuwunikira mwatsatanetsatane kuyenera kuchitidwa kuti mudziwe chomwe chayambitsa ndikuchitapo kanthu koyenera.

Kodi zizindikiro za cholakwika ndi chiyani? P0639?

Zizindikiro zotsatirazi zitha kuchitika ndi DTC P0639:

1. Mavuto ndi kuyambitsa injini.
2. Zowopsa, makamaka pazida zopanda ndale.
3. Injini imayima popanda chenjezo.
4. Kutuluka kwa utsi wakuda kuchokera ku dongosolo lotopetsa poyambitsa galimoto.
5. Kuwonongeka kwa liwiro.
6. Kuwala kwa Check Engine kumabwera.
7. Kumva kukayika pamene mukuthamanga.

Momwe mungadziwire cholakwika P0639?

Gesi ngo malo kachipangizo yomwe ili pa pedal palokha ndipo nthawi zambiri imalumikizidwa kudzera pa mawaya atatu: 5 V yolumikizira voteji, pansi ndi chizindikiro. Yang'anani mawaya kuti muwone ngati pali kulumikizana kotetezeka ndipo palibe malo otayirira. Yang'ananinso pansi pogwiritsa ntchito volt-ohmmeter ndi voteji ya 5V yochokera ku PCM.

Mphamvu yamagetsi iyenera kusiyanasiyana kuchokera ku 0,5 V pomwe pedal sichinapanikizidwe mpaka 4,5 V ikatsegulidwa kwathunthu. Zingakhale zofunikira kuyang'ana chizindikiro pa PCM kuti chifanane ndi sensa. Ma graphical multimeter kapena oscilloscope atha kuthandizira kudziwa kusalala kwa kusintha kwamagetsi pamayendedwe onse.

Malo othamanga ilinso ndi mawaya atatu ndipo imafuna kuyang'ana maulumikizi, nthaka, ndi voteji ya 5V. Yang'anirani kusintha kwa magetsi mukasindikiza pedal ya gasi. Yang'anani injini ya throttle kuti ikukane, yomwe iyenera kukhala mkati mwa fakitale. Ngati kukana sikuli kwachilendo, galimotoyo singasunthe monga momwe ikuyembekezeredwa.

Mphamvu yamagetsi imagwira ntchito potengera chizindikiro chochokera pamalo opondaponda komanso magawo ofotokozedwatu omwe amayendetsedwa ndi PCM/ECM. Yang'anani kukana kwamagalimoto podula cholumikizira ndikugwiritsa ntchito volt-ohmmeter kuti muwonetsetse kuti ili mkati mwazomwe zili mufakitole. Onaninso mawaya pogwiritsa ntchito chithunzi cha fakitale kuti mupeze mawaya olondola.

Pa ntchito ya injini, gwiritsani ntchito graphing multimeter kapena oscilloscope kuti muwonetsetse kuti ikugwirizana ndi kuchuluka kwa PCM/ECM. Chida chojambula chapamwamba chingafunike kuti mufufuze molondola.

Onani throttle thupi chifukwa cha kukhalapo kwa zopinga, dothi kapena mafuta omwe angasokoneze kugwira ntchito kwake.

Onani PCM/ECM pogwiritsa ntchito chida chojambulira kuti muwone ngati siginecha yomwe mukufuna, malo enieni, komanso malo omwe injini yomwe mukufuna ikugwirizana. Ngati zikhalidwe sizikugwirizana, pakhoza kukhala vuto lokana mu waya.

Mawaya amatha kufufuzidwa pochotsa zolumikizira za sensa ndi PCM/ECM ndikugwiritsa ntchito volt-ohmmeter kuti muwone kukana kwa mawaya. Kuwonongeka kwa mawaya kumatha kuyambitsa kulumikizana kolakwika ndi PCM/ECM ndikupangitsa ma code olakwika.

Zolakwa za matenda

Mukazindikira nambala yamavuto ya P0639, makina ambiri nthawi zambiri amalakwitsa kuyang'ana pazizindikiro ndi ma code osungidwa. Njira yabwino kwambiri yothanirana ndi vutoli ndikutsitsa deta ya chimango ndikusanthula ma code mu dongosolo lomwe adasungidwa. Izi zikuthandizani kuti muzindikire molondola ndikuchotsa chomwe chimayambitsa cholakwika P0639.

Kodi zolakwika ndizovuta bwanji? P0639?

Khodi yamavuto P0639, ngakhale sikuti nthawi zonse imayambitsa zovuta zamagalimoto, iyenera kupezeka ndikukonzedwa posachedwa. Ngati sichinasinthidwe, code iyi imatha kubweretsa mavuto akulu monga injini yosayamba kapena kuyima molakwika. Choncho, tikulimbikitsidwa kuti tipeze matenda ndi kukonza kuti tipewe zovuta zomwe zingatheke.

Kodi kukonza kungathandize kuthetsa code? P0639?

Kuti muthane ndi vuto ndikukhazikitsanso kachidindo ka P0639, ndikofunika kuti makaniko anu achite izi:

1. Bwezerani zingwe zilizonse zosalongosoka kapena zowonongeka, zolumikizira kapena zigawo zomwe zimagwirizanitsidwa ndi throttle system.
2. Ngati kulephera kwa throttle valve drive motor kwapezeka, iyenera kusinthidwa ndi yogwira ntchito.
3. Ngati ndi kotheka, m'malo lonse throttle thupi, kuphatikizapo throttle udindo sensa, monga analimbikitsa ndi Mlengi.
4. Mukasintha thupi la throttle, makinawo akuyeneranso kuganiziranso kusintha kachipangizo ka pedal, ngati atchulidwa.
5. Sinthani ma module onse owongolera olakwika, ngati alipo.
6. Lumikizani kapena sinthani zolumikizira zamagetsi zotayirira, zowonongeka kapena zowonongeka mudongosolo.
7. Sinthani mawaya aliwonse osokonekera mu hatchi ya basi ya CAN ngati adziwika kuti ndiye gwero la vuto.

Kuzindikira mosamalitsa ndikukhazikitsa njira zomwe zatchulidwazi kumathandizira kuchotsa nambala ya P0639 ndikubwezeretsa galimotoyo kuti igwire bwino ntchito.

P0639 - Zambiri zokhudzana ndi mtundu

Khodi yamavuto P0639 ilibe tanthauzo lenileni lamtundu wagalimoto. Khodi iyi ikuwonetsa zovuta za pedal kapena throttle position sensor ndipo imatha kuchitika pamapangidwe osiyanasiyana ndi mitundu yamagalimoto. Kuzindikira ndi kuthetsa vutoli kumadalira galimoto yeniyeni ndi kayendetsedwe kake. Kuti mudziwe zolondola komanso njira yothetsera vutoli, tikulimbikitsidwa kuti mulumikizane ndi zolemba zautumiki kapena katswiri wokonza magalimoto omwe amadziwika ndi mtundu wina.
