I-Crankshaft Position Sensor B Ukungasebenzi Kwesekethe

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezihlomile ze-OBD-II (iHonda, GMC, Chevrolet, Ford, Volvo, Dodge, Toyota, njll.). Yize kuvamile emvelweni, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli.

Uma imoto yakho inekhodi egciniwe engu-P0389, kusho ukuthi imodyuli yokulawula amandla we-powertrain (PCM) ithole isignali yamandla kagesi aphakathi nendawo noma ngezikhathi ezithile kusuka kunzwa yesibili ye-crankshaft position (CKP). Lapho izinzwa eziningi ze-CKP zisetshenziswa ohlelweni lwe-OBD II, inzwa B ivame ukubizwa ngokuthi inzwa yesibili ye-CKP.

Ijubane le-injini (i-rpm) ne-crankshaft position kubhekwa inzwa ye-CKP. I-PCM ibala isikhathi sokushisa isebenzisa isikhundla se-crankshaft. Uma ucabanga ukuthi ama-camshafts ajikeleza ngesigamu se-crankshaft, ungabona ukuthi kungani kubaluleke kangaka ukuthi i-PCM ikwazi ukuhlukanisa phakathi kokushaywa yizinjini nokukhipha (RPM). Imijikelezo yenzwa ye-CKP ifaka isekethe elilodwa noma amaningi ukuhlinzeka ngesiginali yokufaka, ireferensi ye-5V, kanye nomhlabathi ku-PCM.

Izinzwa ze-CKP ngokuvamile ziyizinzwa ze-electromagnetic Hall effect. Zivamise ukugxunyekwa ngaphandle kwenjini futhi zibekwe eduze (imvamisa kuphela izinkulungwane ezimbalwa zamayintshi) kumjikelezo wemotor ground. Umhlabathi wenjini uvamise ukuba yindandatho yokusabela (ngamazinyo enziwe ngokunemba) enamathiselwe kunoma iyiphi indawo ye-crankshaft noma eyakhelwe ku-crankshaft uqobo. Amanye amasistimu anezinzwa zokuma kwe-crankshaft amaningi angase asebenzise iringi yokusabela ekugcineni kwe-crankshaft kanti enye phakathi nendawo ye-crankshaft. Abanye bavele bafake izinzwa ezindaweni eziningi eduze kweringi eyodwa ye-reactor.

Inzwa ye-CKP ifakwe ukuze iringi yesiphenduli inwebe ngaphakathi kwezinkulungwane ezimbalwa zamasentimitha wethiphu yayo kazibuthe njengoba i-crankshaft ijikeleza. Izingxenye eziphumayo (amazinyo) endandatho yokuphendula zivala isekethe kagesi ngenzwa, futhi ikhefu eliphakathi kwamaprosesa liphazamisa isifunda okwesikhashana. I-PCM iyazibona lezi zimfushane eziqhubekayo nokuphazamiseka njengephethini yamagagasi amelela ukuguquguquka kwamandla kagesi.

Izimpawu zokufaka ezivela ezinzwa ze-CKP zihlale ziqashwe yi-PCM. Uma i-voltage yokufaka enzwa ye-CKP iphansi kakhulu isikhathi esithile, ikhodi ye-P0389 izogcinwa futhi i-MIL ingakhanyisa.

Amanye ama-DKs we-CKP Sensor B afaka i-P0385, P0386, P0387, ne-P0388.

Ukuqina kwekhodi nezimpawu

Akunasimo sokuqala okungenzeka sihambisane nekhodi eligcinwe nge-P0389. Ngakho-ke, le khodi ingahlukaniswa njengebucayi.

Izimpawu zale khodi zingafaka:

Le njini ayifuni ukuduma
I-tachometer (uma ifakwe) ayibhalisi i-RPM lapho injini ishaya.
Ukuxoshwa ekusheshiseni
Ukusebenza kabi kwenjini
Ukunciphisa ukusebenza kwephethiloli

izizathu

Izizathu ezingaba khona zokusetha le khodi:

Inzwa ye-CKP enamaphutha
Isifunda esivulekile noma esifushane ezintanjeni zenzwa ye-CKP
Isixhumi esifakwe uketshezi noma uketshezi kumzwa we-CKP
Iphutha lokuhlela le-PCM noma le-PCM elingalungile

Izinqubo zokuxilonga nokulungisa

Ngizodinga isithwebuli sokuxilonga esakhelwe ngaphakathi i-digital volt / ohmmeter (DVOM) ne-oscilloscope ngaphambi kokuthola ikhodi ye-P0389. Uzodinga futhi nomthombo onokwethenjelwa wolwazi lwemoto njenge-All Data DIY.

Ukuhlolwa okubonakalayo kwawo wonke amahhanisi ezintambo ahlobene nesistimu nezixhumi kuyindawo enhle yokuqala ukuhlonza. Amasekethi angcoliswe uwoyela wenjini, okokupholisa, noma uketshezi lwesiteringi kufanele ahlolwe ngokucophelela njengoba uketshezi olususelwa ku-petroleum lungonakalisa ukufakwa kwezintambo futhi lubangele izikhindi noma amasekhethi avulekile (kanye ne-P0389 egciniwe).

Uma ukuhlolwa okubukwayo kwehluleka, xhuma isithwebuli ethekwini lokuxilonga lemoto bese ubuyisa wonke ama-DTC agciniwe bese uqandisa idatha yozimele. Ukurekhoda lolu lwazi kungasiza uma i-P0389 kutholakala ukuthi ayizinzile. Uma kungenzeka, hlola ukushayela imoto ukuze uqiniseke ukuthi ikhodi isuliwe.

Uma i-P0389 isethwe kabusha, thola umdwebo wiring wesistimu emthonjeni wolwazi lwemoto bese uhlola i-voltage kuzinzwa ze-CKP. I-voltage yesethenjwa ivame ukusetshenziselwa ukusebenzisa inzwa ye-CKP, kepha hlola imininingwane yomkhiqizi wemoto okukhulunywa ngayo. Isekethe elilodwa noma amaningi okukhipha nesiginali yomhlabathi nayo izobe ikhona. Uma izinkomba zamandla ombane nezomhlabathi zitholakala kusixhumi senzwa ye-CKP, iya esinyathelweni esilandelayo.

Usebenzisa i-DVOM, hlola i-CKP okukhulunywa ngayo ngokuya ngezincomo zomkhiqizi. Uma amazinga okumelana nenzwa ye-CKP engahambisani nezincomo zomkhiqizi, sola ukuthi inephutha. Uma ukumelana kwenzwa ye-CKP kufana nokucaciswa komkhiqizi, qhubekela esinyathelweni esilandelayo.

Xhuma ukuhola okuhle kokuhlolwa kwe-oscilloscope kokuhola okukhipha isignali kanye nokuhola okungekuhle kumjikelezo womhlabathi wenzwa ye-CKP ngemuva kokuxhuma kabusha inzwa ye-CKP ehambisanayo. Khetha ukulungiselelwa kwamandla kagesi ku-oscilloscope bese uyivula. Bheka ukwakheka kwe-wave kwi-oscilloscope ngenjini edling, epaki noma engathathi hlangothi. Qaphela ama-power surges noma amaphutha we-waveform. Uma kutholakala okungafani kahle, hlola amahanisi nesixhumi (ngenzwa ye-CKP) ukuthola ukuthi inkinga ukuxhumana okuxekethile noma inzwa engalungile. Uma kunenqwaba yemfucumfucu yensimbi onqenqemeni lukazibuthe lwenzwa ye-CKP, noma uma kunendandatho ekhanyayo noma egqokile, lokhu kungaholela ekutheni kungabi namabhuloki ombane kuphethini yamagagasi. Uma kungekho nkinga etholakala kuphethini lefomu le-waveform, qhubekela esinyathelweni esilandelayo.

Thola isixhumi se-PCM bese ufaka isivivinyo se-oscilloscope esiholela ekufakweni kwesiginali yenzwa ye-CKP nokuxhuma komhlaba ngokulandelana. Bheka isimo se-waveform. Uma isampula yokuguqula amagagasi eduze kwesixhumi se-PCM yehlukile kulokho okwakubonwa lapho izivivinyo zokuhlola zixhunywe eduze kwenzwa ye-CKP, sola isekhethi evulekile noma emfushane phakathi kwesixhumi senzwa se-CKP nesixhumi se-PCM. Uma kuyiqiniso, nqamula bonke abalawuli abahlobene futhi uhlole amasekethe ngamanye nge-DVOM. Uzodinga ukulungisa noma ukufaka amanye amasekethe avulekile noma avaliwe. I-PCM ingahle ibe nephutha, noma ungaba nephutha lohlelo lwe-PCM uma iphethini yefomu ye-wave ifana nalokho okwakubonwa lapho umkhondo wokuhlolwa uxhunywe eduze kwenzwa ye-CKP.

Amanothi wokuxilonga angeziwe:

Abanye abakhiqizi batusa ukufaka izinzwa ze-CKP ne-CMP njengengxenye yekhithi.
Sebenzisa ama-bulletin wensiza ukusiza ngenqubo yokuxilonga

Izingxoxo ezihlobene ze-DTC

2005 I-Acura yashintsha ibhande lesikhathi, P0389Ngishintshe ibhande lesikhathi kanye nepompo yamanzi ukuze ngikhanyise injini nezibani ze-VSA (zombili "VSA" kanye "!"). Inombolo yepholisi: P0389 Ngazama ukusetha kabusha izilungiselelo, kodwa ngokushesha kuvela. Uhlole wonke amamaki esikhathi futhi konke kubukeka kukuhle. Ngicela unginikeze izeluleko ezinhle !!!…

Udinga usizo olwengeziwe ngekhodi le-p0389?

Uma usadinga usizo nge-DTC P0389, thumela umbuzo kumazwana angezansi kwalesi sihloko.

QAPHELA. Lolu lwazi lunikezwa ngenhloso yokwaziswa kuphela. Akuhloselwe ukuthi isetshenziswe njengesincomo sokulungisa futhi asinacala nganoma yisiphi isenzo osithathayo kunoma iyiphi imoto. Yonke imininingwane ekulesi siza ivikelwe yi-copyright.
