Crankshaft Position Sensor B Dunhu Kusashanda
Izvi zvinorevei?
Iyi Yekuongorora Dambudziko Kodhi (DTC) ndiyo yakajairika kodhi yekufambisa, zvinoreva kuti inoshanda kune OBD-II mota dzakashongedzwa (Honda, GMC, Chevrolet, Ford, Volvo, Dodge, Toyota, nezvimwewo). Kunyangwe zvakajairika mune zvakasikwa, chaiwo matanho ekugadzirisa anogona kusiyana zvichienderana neiyo mhando / modhi.
Kana mota yako iine kodhi yakachengetwa P0389, zvinoreva kuti powertrain control module (PCM) yaona chiratidzo chemagetsi kana chepakati kubva kune yechipiri crankshaft nzvimbo (CKP) sensor. Kana akawanda maKKP sensors achishandiswa muODB II system, sensor B inowanzozonzi sechipiri CKP sensor.
Injini kumhanya (rpm) uye crankshaft chinzvimbo chinotariswa neCKP sensor. Iyo PCM inoverenga nguva yekuvesa uchishandisa chinzvimbo che crankshaft. Paunofunga kuti macamshafts anotenderera pahafu yemakirabhu emahara, unogona kuona kuti nei zvichikosha zvekuti PCM inogona kusiyanisa pakati pekurohwa kweinjini uye kupera (RPM). Iyo CKP sensor wedunhu inosanganisira imwe kana anopfuura macircuit ekupa chiratidzo chekupinza, chitauro che5V, uye pasi kune PCM.
CKP sensors kazhinji kazhinji electromagnetic Hall effect sensors. Anowanzo kukwidzwa kunze kumota uye anoiswa padhuze (kazhinji chete zviuru zvishoma zvema inch) kune mota yepasi redunhu. Injini yepasi inowanzoita mhete (ine mazino akagadzirwa chaiwo) akasungirirwa kune imwe magumo e crankshaft kana kuvakwa mukati me crankshaft pachayo. Mamwe masisitimu ane akawanda crankshaft chinzvimbo sensors anogona kushandisa reaction ring kune imwe magumo e crankshaft uye imwe iri pakati pe crankshaft. Vamwe vanongoisa masensa munzvimbo dzakawanda dzakatenderedza mhete imwe chete yereactor.
Iyo CKP sensor yakaiswa kuitira kuti iyo reactor ringi inosvika mukati memazana mashoma ezviuru zvemasentimita eayo magineti tip sezvo crankshaft inotenderera. Izvo zvinobuda zvikamu (mazino) zveyakagadziriswa mhete inovhara magetsi emagetsi neiyo sensor, uye pakadzika pakati pezvakakomberedza zvinokanganisa dunhu. Iyo PCM inoona izvi zvinopfuurira zvikabudura uye zvinokanganisa seyveformform pateni inomiririra kuchinja kwemagetsi.
Zviratidzo zvekuisa kubva kuCKP sensors zvinogara zvichiongororwa nePCM. Kana iwo magetsi ekuisa kune iyo CKP sensor yakanyanya kuderera kwenguva yakatarwa, P0389 kodhi inochengetwa uye iyo MIL inogona kuvhenekera.
Mamwe maCKP Sensor B DTCs anosanganisira P0385, P0386, P0387, uye P0388.
Kodhi kuomarara uye zviratidzo
Iyo isina mamiriro ekutanga inowanzo perekedza yakachengetwa P0389 kodhi. Naizvozvo, kodhi iyi inogona kusarudzwa seyakakomba.
Zviratidzo zvekodhi iyi zvinogona kusanganisira:
- Injini haisi kuzotanga
- Iyo tachometer (kana yakashongedzerwa) haina kunyoresa iyo RPM kana injini ichinyura.
- Oscillation pakumhanyisa
- Inotadza injini kuita
- Yakaderedzwa mafuta anoshanda
zvikonzero
Zvimwe zvikonzero zvekumisikidza kodhi iyi:
- Inokanganisa CKP sensor
- Vhura kana pfupi dunhu mune wiring yeiyo CKP sensor
- Yakagadziriswa kana yakasviba-yakanyorovera chinongedzo pane iyo CKP sensor
- Yakakanganisa PCM kana PCM yekukanganisa kukanganisa
Kuongorora uye kugadzirisa maitiro
Ini ndoda scanner yekuongorora ine yakavakirwa-mudhijitari volt / ohmmeter (DVOM) uye oscilloscope usati waongorora iyo P0389 kodhi. Iwe zvakare unozoda yakavimbika sosi yemotokari ruzivo senge All Dhata DIY.
Ongororo yekuona yeese ane hukama-ane tambo mawaya uye zvibatanidza inzvimbo yakanaka yekutanga kuongorora. Masenhu akasvibiswa neoiri yeinjini, inotonhodza, kana kuti magetsi anofambisa magetsi anofanirwa kunyatsoongororwa sezvo mvura ine petroleum inogona kukanganisa kuvharisa waya uye kukonzera zvikabudura kana maseketi akavhurika (uye P0389 yakachengetwa).
Kana kutariswa kwekutarisa kukatadza, batanidza iyo scanner kune chiteshi chekuongorora mota uye udzore ese akachengetedzwa maDTC uye gonesa dhata data. Kunyora ruzivo urwu kunogona kubatsira kana P0389 ikawanikwa isina kugadzikana. Kana zvichibvira, edza kutyaira mota kuti uone kuti kodhi yabviswa.
Kana P0389 yadzoswazve, tsvaga iyo system wiring dhayagiramu kubva kumotokari ruzivo sosi uye tarisa iyo voltage kuCKP sensor. Iyo voltage voltage inowanzo shandiswa kushandisa iyo CKP sensor, asi tarisa izvo zvinogadzirwa nemugadziri wemotokari iri kutaurwa. Imwe kana yakawanda inoburitsa macircuit uye pasi chiratidzo chichave chiripo. Kana mareferenzi emagetsi nemasaini epasi akawanikwa paCKP sensor connector, enda padanho rinotevera.
Uchishandisa iyo DVOM, edza iyo CKP iri mubvunzo maererano nezvakakurudzirwa nemugadziri. Kana iwo ekumira kweiyo CKP sensor isingaenderane nezvakakurudzirwa nemugadziri, fungidzira kuti haina kukwana. Kana kushora kweiyo CKP sensor kunoenderana nezvakatemwa nemugadziri, enderera padanho rinotevera.
Unganidza iyo chaiyo bvunzo yekuyera yeiyo oscilloscope kune chiratidzo chinoburitsa lead uye yakashata inotungamira kune yepasi sedunhu reiyo CKP sensor mushure mekubatanidzazve inoenderana CKP sensor. Sarudza iyo yakakodzera magetsi kuisa pane oscilloscope uye woibatidza. Cherekedza iyo waveform pane oscilloscope neinjini idling, paki kana kwazvakarerekera. Chenjerera masimba emagetsi kana kukanganisa kwemafungu. Kana paine zvisirizvo zvakawanikwa, edza iyo harness uye chinongedzo (cheiyo CKP sensor) kuti uone kana dambudziko iri rakasununguka kubatana kana inokanganisa sensor. Kana paine huwandu hwakawandisa hwesimbi pane iyo magnetic tip yeCKP sensor, kana kana paine yakapwanyika kana yakasakara mhete yekuratidzira, izvi zvinogona kukonzeresa kuve nemagetsi anovharira muiyo waveform pateni. Kana pasina dambudziko richiwanikwa muiyo waveform pateni, pfuurira kunhanho inotevera.
Tsvaga iyo PCM yekubatanidza uye isa iyo oscilloscope bvunzo inotungamira muCKP sensor chiratidzo yekuisa uye yekubatana kwepasi zvakateedzana. Cherekedza iyo waveform. Kana iyo waveform sampuro padhuze nePCM chinobatanidza yakasiyana nezvakaonekwa apo bvunzo inotungamira yakabatana padyo neCKP sensor, fungidzira yakavhurika kana ipfupi dunhu pakati peCKP sensor yekubatanidza uye PCM yekubatanidza. Kana ichokwadi, bvisa vatongi vese vane hukama uye bvunzo maseketi ega neDVOM. Iwe unozofanirwa kugadzirisa kana kutsiva maseketi akavhurika kana akavharwa. Iyo PCM inogona kunge iine chakaremara, kana iwe unogona kunge uine PCM yekukanganisa kukanganisa kana iyo waveform pateni yakafanana nezvakaonekwa apo bvunzo inotungamira yakabatana padyo neCKP sensor.
Zvimwe zvekuongorora manotsi:
- Vamwe vagadziri vanokurudzira kutsiva CKP uye CMP sensors sechikamu chekiti.
- Shandisa mabulletin ebasa kubatsira nehurongwa hwekuongorora
Inoenderana DTC hurukuro
- 2005 Acura yakachinja nguva bhandi, P0389Ndakatsiva bhandi renguva uye pombi yemvura chete kuti injini neVSA mwenje zviuye (zvese "VSA" uye "!"). Iyo kodhi ndeye P0389. Ndakaedza kuseta zvakare marongero, asi pakarepo inobuda. Yakatariswa ese maki enguva uye zvese zvinotaridzika zvakanaka. Ungapawo zano rakanaka ndapota !!!…
Unoda rumwe rubatsiro neiyo p0389 kodhi?
Kana iwe uchiri kuda rubatsiro neDTC P0389, tumira mubvunzo mune zvakataurwa pazasi peichi chinyorwa.
ONA. Ruzivo urwu rwunopihwa ruzivo rwezvinangwa chete. Izvo hazvina kuitirwa kuti ishandiswe sekurudziro yekugadzirisa uye isu hatisi ivo vane basa kune chero chiito iwe chaunotora pane chero mota. Zvese ruzivo pane ino saiti zvinodzivirirwa ne copyright.
