P0641 Ukujikeleza okuvulekile kwenzwa I-voltage yesethenjwa

Ikhodi Yenkinga ye-OBD-II - P0641 - Ishidi Ledatha

I-P0641 - I-Sensor A Reference Voltage Circuit Open

Isho ukuthini ikhodi yenkinga P0641?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezihlomele i-OBD-II. Yize kuvamile emvelweni, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli.

Lapho ngithola ikhodi egcinwe i-P0641, kusho ukuthi imodyuli yokulawula i-powertrain (PCM) ithole isekethe evulekile yenzwa ethile; ichazwe kuleli cala njengo- "A". Lapho uthola ikhodi ye-OBD-II, igama elithi "vula" lingashintshwa ngelithi "lilahlekile".

Inzwa okukhulunywa ngayo ivamise ukuhlotshaniswa nokudlulisa okuzenzakalelayo, ikesi lokudlulisa, noma okunye okuhlukile. Le khodi ihlale ilandelwa yikhodi yenzwa ecaciswe kakhulu. I-P0641 yengeza ukuthi isifunda sivuliwe. Bheka umthombo othembekile wolwazi lwemoto (Yonke Idatha i-DIY iyinketho enhle) ukuze unqume indawo (nomsebenzi) wenzwa ehlobene nemoto okukhulunywa ngayo. Uma i-P0641 igcinwe ngokuhlukile, sola ukuthi kwenzeke iphutha lokuhlela le-PCM. Ngokusobala uzodinga ukuxilonga futhi ulungise noma yimaphi amanye amakhodi enzwa ngaphambi kokuxilonga nokulungisa i-P0641, kodwa qaphela isekethe evulekile ethi "A".

Isethenjwa samandla kagesi (imvamisa ama-volts amahlanu) sisetshenziselwa inzwa okukhulunywa ngayo ngesekethe eshintshekayo (enikwe amandla okhiye). Kufanele futhi kube nesiginali yomhlabathi. Inzwa kungenzeka ukuthi ibe nokumelana okuguqukayo noma ukuhlukahluka kwe-electromagnetic futhi ivala isekethe ethile. Ukumelana kwenzwa kuncipha ngokucindezela okwandayo, izinga lokushisa noma isivinini futhi okuphambene nalokho. Njengoba ukumelana kwenzwa kushintsha nezimo, kunikeza i-PCM isiginali yamandla wokufaka. Uma lesi siginali sokufaka samandla kagesi singatholwa yi-PCM, isifunda sithathwa njengesivulekile futhi kuzogcinwa i-P0641.

I-Malfunction Indicator Lamp (MIL) nayo ingakhanyiswa, kepha yazi ukuthi ezinye izimoto zizothatha imijikelezo eminingi yokushayela (ngokungasebenzi kahle) ukuze i-MIL ivule. Ngalesi sizathu, kufanele uvumele i-PCM ukuthi ifake imodi yokulinda ngaphambi kokucabanga ukuthi noma ikuphi ukulungiswa kuphumelele. Vele ususe ikhodi ngemuva kokulungiswa bese ushayela njengokujwayelekile. Uma i-PCM ingena kumodi yokulungela, ukulungiswa kuphumelele. Uma ikhodi isuliwe, i-PCM ngeke ingene kumodi ekulungele futhi uzokwazi ukuthi inkinga isekhona.

Ubunzima nezimpawu

Ubunzima be-P0641 egciniwe buxhomeke ekutheni isifunda senzwa sisesimweni esivulekile. Ngaphambi kokuthola ubunzima, udinga ukubuyekeza amanye amakhodi agciniwe.

Izimpawu zekhodi ye-P0641 zingafaka:

• Ukwehluleka ukushintsha ukudluliswa phakathi kwezinhlobo zezemidlalo nezomnotho
• Ukungasebenzi kahle kwamagiya
• Ukubambezeleka (noma ukuntuleka) kokuvula ukudluliswa
• Ukwehluleka kokudlulisa ukushintsha phakathi kwe-XNUMXWD ne-XNUMXWD
• Ukwehluleka kwecala lokudlulisa ukusuka kokuphansi kuya kugiya eliphezulu
• Ukuntuleka kokufakwa komehluko wangaphambili
• Ukuntuleka kokuzibandakanya kwehabhu langaphambili
• I-speedometer / i-odometer engalungile noma engasebenzi

Izimbangela zephutha P0641

Izimbangela ezingaba khona zale khodi yenjini zifaka:

• Isifunda esivulekile kanye / noma izixhumi
• Amafyuzi anamaphutha noma afuthwe kanye / noma amafusizi
• Ukudluliswa kwamandla wesistimu okungalungile
• Inzwa engalungile
• Imojula yokulawula injini engasebenzi (ECM)
• Ihhashi le-ECM livuliwe noma lifushane
• Isekhethi kagesi engalungile i-ECM
• Inzwa ifushanisiwe ukuze ibe ngu-5 volts Kusho ukuthini lokhu?

Izinqubo zokuxilonga nokulungisa

Ukuthola ikhodi egciniwe ye-P0641, ngizodinga ukufinyelela kuskena sokuxilonga, i-digital volt / ohmmeter (i-DVOM), nomthombo othembekile wolwazi lwemoto (njenge-All Data DIY). I-oscilloscope ephathekayo nayo ingaba wusizo ezimweni ezithile.

Sebenzisa umthombo wolwazi wemoto yakho ukuthola indawo nokusebenza kwenzwa okukhulunywa ngayo njengoba ihlobene nemoto yakho ethize. Hlola amafyuzi wesistimu namafyuzi womthwalo ogcwele. Amafiyuzi angahle abonakale ejwayelekile lapho isifunda silayishwe kancane, imvamisa yehluleka lapho isifunda silayishwe ngokugcwele. Ama-fuse aqhephukile kufanele athathelwe indawo, kukhunjulwe ukuthi isifunda esifushane kungenzeka ukuthi siyimbangela yefuse eqhutshwe.

Hlola ngokubonakalayo amahanisi nezixhumi ezihambisana nohlelo lwenzwa. Lungisa noma buyisela izintambo ezilimele noma ezishisiwe, izixhumi, nezakhi njengoba kudingeka.

Ngibe sengixhuma isithwebuli kusokhethi yokuxilonga imoto ngathola wonke ama-DTC agciniwe. Ngithanda ukuwabhala phansi kanye nanoma iyiphi idatha yozimele efriziwe, njengoba lolu lwazi lungasiza uma ikhodi ivele ibe yinhle. Ngemuva kwalokho, bengizoqhubeka ngicishe ikhodi bese ngivivinya ukushayela imoto ukubona ukuthi isetha kabusha ngokushesha.

Uma onke amafiyuzi wesistimu elungile futhi ikhodi isetha kabusha ngokushesha, sebenzisa i-DVOM ukuhlola amandla wesethenjwa namasiginali womhlaba kunzwa okukhulunywa ngayo. Ngokuvamile, kufanele ulindele ukuba nama-volts amahlanu nendawo ovumelana ngayo kusixhumi senzwa.

Uma ama-voltage namasiginali womhlaba akhona kusixhumi senzwa, qhubeka nokuhlola ukumelana kwenzwa namazinga wobuqotho. Sebenzisa umthombo wolwazi lwemoto yakho ukuthola imininingwane yokuhlolwa bese uqhathanisa imiphumela yakho yangempela nayo. Izinzwa ezingahlangabezani nalezi zibaluli kufanele zishintshwe.

Nqamula bonke abalawuli abahlobene nohlelo ngaphambi kokuhlola ukumelana ne-DVOM. Uma ingekho i-voltage reference signal enzwa, nqamula zonke izilawuli ezihambisanayo bese usebenzisa i-DVOM ukuhlola ukumelana kwesifunda nokuqhubeka phakathi kwenzwa ne-PCM. Shintsha amasekethe avulekile noma afushane lapho kudingeka. Uma usebenzisa inzwa ye-electromagnetic ephindayo, sebenzisa i-oscilloscope ukulandelela idatha ngesikhathi sangempela; ukunaka kakhulu ama-glitches namasekethe avulekile ngokuphelele.

Amanothi wokuxilonga angeziwe:

• Lolu hlobo lwekhodi luvame ukuhlinzekwa njengokusekelwa kwekhodi ethile.
• Ikhodi egciniwe engu-P0641 imvamisa ihlotshaniswa nokudluliswa.
