Crankshaft Matsayin Sensor B Circuit Malfunction

Mene ne wannan yake nufi?

Wannan Lambar Matsalar Bincike (DTC) lambar watsawa ce gaba ɗaya, wanda ke nufin ya shafi motocin OBD-II sanye da kayan (Honda, GMC, Chevrolet, Ford, Volvo, Dodge, Toyota, da sauransu). Kodayake gabaɗaya, takamaiman matakan gyara na iya bambanta dangane da alama / ƙirar.

Idan abin hawan ku yana da lambar da aka adana P0389, yana nufin tsarin kula da wutar lantarki (PCM) ya gano siginar wutar lantarki ta tsaka -tsaki ko tsaka -tsaki daga firikwensin crankshaft na biyu (CKP). Lokacin da ake amfani da firikwensin CKP da yawa a cikin tsarin OBD II, yawanci ana kiran firikwensin B azaman firikwensin CKP na biyu.

Ana lura da saurin injin (rpm) da matsayin crankshaft ta firikwensin CKP. PCM yana ƙididdige lokacin ƙonewa ta amfani da matsayin maƙogwaron. Lokacin da kuka yi la’akari da cewa camshaft ɗin yana jujjuyawa a cikin rabin crankshaft gudun, zaku iya ganin dalilin da yasa yake da mahimmanci ga PCM ya sami damar rarrabe tsakanin bugun injin da shaye shaye (RPM). Circuit na firikwensin CKP ya haɗa da ɗaya ko fiye da'irori don samar da siginar shigarwa, nuni na 5V, da ƙasa zuwa PCM.

Na'urori masu auna firikwensin CKP galibi sune firikwensin tasirin Hall na lantarki. Yawancin lokaci ana hawa su waje zuwa motar kuma ana sanya su a kusanci (yawanci ƴan dubunnan inch kawai) zuwa da'irar ƙasan motar. Ƙasar injin yawanci zobe ne na amsawa (tare da madaidaicin hakora) a haɗe zuwa ko dai ƙarshen crankshaft ko an gina shi a cikin crankshaft kanta. Wasu tsarin tare da na'urori masu auna firikwensin matsayi masu yawa na iya amfani da zoben amsawa a ƙarshen crankshaft da ɗayan a tsakiyar crankshaft. Wasu kawai suna shigar da na'urori masu auna firikwensin a wurare da yawa a kusa da zobe ɗaya na reactor.

An ɗora firikwensin CKP don zoben reactor ya faɗaɗa tsakanin fewan dubban inci na faifan maganadisun sa yayin da crankshaft ke juyawa. Sassan da ke fitowa (hakora) na zoben reactor suna rufe da'irar electromagnetic tare da firikwensin, kuma ramukan da ke tsakanin tsinkayen sun katse kewaye. PCM tana gane waɗannan gajerun gajeren wando da katsewa azaman ƙirar ƙirar igiyar ruwa tana wakiltar canjin ƙarfin lantarki.

Alamar shigarwar daga firikwensin CKP ana kula da PCM akai -akai. Idan ƙarfin shigarwar zuwa firikwensin CKP ya yi ƙasa sosai don takamaiman lokacin, za a adana lambar P0389 kuma MIL na iya haskakawa.

Sauran CKP Sensor B DTC sun haɗa da P0385, P0386, P0387, da P0388.

Ƙarfin lamba da alamu

Yanayin farawa ba zai yiwu ya bi lambar P0389 da aka adana ba. Sabili da haka, ana iya rarrabe wannan lambar da mahimmanci.

Alamomin wannan lambar na iya haɗawa da:

• Injin din ya ki ya taso
• Tachometer (idan an sanye shi) baya yin rijistar RPM lokacin da injin ɗin ke murƙushewa.
• Oscillation akan hanzari
• Ayyukan injin mara kyau
• Rage ingancin man fetur

dalilai

Dalilai masu yiwuwa don saita wannan lambar:

• Raunin firikwensin CKP
• Buɗe ko gajeriyar kewaye a cikin wayoyin firikwensin CKP
• Mai haɗawa mai ruɓe ko ruwa mai ɗumi a kan firikwensin CKP
• Kuskuren shirye -shiryen PCM ko PCM

Hanyoyin bincike da gyara

Zan buƙaci na'urar bincike tare da ginanniyar volt / ohmmeter (DVOM) da oscilloscope kafin in bincika lambar P0389. Hakanan kuna buƙatar ingantacciyar hanyar bayanan abin hawa kamar All Data DIY.

Duban gani na duk kayan aikin wayoyi masu alaƙa da tsarin da masu haɗawa wuri ne mai kyau don fara ganowa. Ya kamata a bincika da'irori da aka gurbata da man inji, na'urar sanyaya, ko ruwan tuƙin wutar lantarki a hankali kamar yadda ruwan da ake amfani da shi na man fetur zai iya yin illa ga rufewar waya kuma ya haifar da gajeren wando ko buɗe da'ira (da P0389 da aka adana).

Idan dubawa na gani ya gaza, haɗa na'urar daukar hotan takardu zuwa tashar binciken abin hawa kuma dawo da duk DTC da aka adana da daskare bayanan firam. Yin rikodin wannan bayanin na iya taimakawa idan P0389 aka sami rashin daidaituwa. Idan za ta yiwu, gwada gwajin abin hawa don tabbatar an share lambar.

Idan an sake saita P0389, nemo ƙirar ƙirar tsarin daga tushen bayanan abin hawa kuma duba ƙarfin lantarki a firikwensin CKP. Ana amfani da ƙarfin ƙarfin tunani don sarrafa firikwensin CKP, amma bincika ƙayyadaddun masana'anta don abin hawa da ake tambaya. Oneaya ko fiye da'irar fitarwa da siginar ƙasa ma za su kasance. Idan ana samun ƙarfin ƙarfin tunani da siginar ƙasa a mai haɗa firikwensin CKP, je zuwa mataki na gaba.

Amfani da DVOM, gwada CKP da ake tambaya bisa ga shawarwarin masana'anta. Idan matakan juriya na firikwensin CKP basu dace da shawarwarin masu ƙira ba, yi zargin cewa yana da lahani. Idan juriya na firikwensin CKP yayi daidai da ƙayyadaddun masana'anta, ci gaba zuwa mataki na gaba.

Haɗa madaidaicin gwajin gwaji na oscilloscope zuwa gubar fitowar siginar da madaidaicin jagora zuwa kewayen ƙasa na firikwensin CKP bayan sake haɗa firikwensin CKP mai dacewa. Zaɓi saitin ƙarfin lantarki da ya dace akan oscilloscope kuma kunna shi. Dubi tsarin jujjuyawar a kan oscilloscope tare da injin da ke kwance, shakatawa ko tsaka tsaki. Yi hankali don ƙarar wutar lantarki ko kuskuren motsi. Idan an sami rashin daidaituwa, gwada kayan doki da mai haɗawa (don firikwensin CKP) don sanin idan matsalar ta kasance sako -sako na haɗi ko firikwensin firikwensin. Idan akwai tarkacen ƙarfe da ya wuce kima a kan faifan magnetic na firikwensin CKP, ko kuma idan akwai ɓoyayye ko saƙar zoben mai haskakawa, wannan na iya haifar da babu tubalan wutar lantarki a cikin tsarin motsi. Idan ba a sami matsala ba a tsarin ƙirar igiyar ruwa, ci gaba zuwa mataki na gaba.

Nemo wurin haɗin PCM kuma shigar da gwajin oscilloscope yana shiga cikin shigarwar siginar firikwensin CKP da haɗin ƙasa bi da bi. Dubi tsarin motsi. Idan samfurin raƙuman ruwa kusa da mai haɗin PCM ya bambanta da abin da aka gani lokacin da aka haɗa jagororin gwajin kusa da firikwensin CKP, yi shakkar buɗewa ko gajere kewaye tsakanin mai haɗa firikwensin CKP da mai haɗa PCM. Idan gaskiya ne, cire haɗin duk masu kula da abin da ke da alaƙa da gwada madaidaiciyar madaidaiciya tare da DVOM. Kuna buƙatar gyara ko maye gurbin da'irori masu buɗewa ko rufewa. PCM na iya zama aibi, ko kuma kuna iya samun kuskuren shirye -shiryen PCM idan ƙirar raƙuman ruwa daidai yake da abin da aka gani lokacin da aka haɗa jagororin gwajin kusa da firikwensin CKP.

Ƙarin bayanin kula:

• Wasu masana'antun suna ba da shawarar maye gurbin CKP da CMP firikwensin azaman ɓangaren kit ɗin.
• Yi amfani da sanarwar sabis don taimakawa tare da tsarin bincike

Tattaunawar DTC mai dangantaka

• 2005 Acura ya canza bel ɗin lokaci, P0389Na maye gurbin bel na lokaci da famfon ruwa kawai don in sami injin da fitilun VSA (duka "VSA" da "!"). Lambar kwanan wata ita ce P0389. Na yi ƙoƙarin sake saita saitunan, amma nan da nan ya tashi. An duba duk alamun lokaci kuma komai yayi kyau. Za a iya ba da shawara mai kyau don Allah !!!… 

Kuna buƙatar ƙarin taimako tare da lambar ku ta p0389?

Idan har yanzu kuna buƙatar taimako tare da DTC P0389, aika tambaya a cikin sharhin da ke ƙasa wannan labarin.

NOTE. An ba da wannan bayanin don dalilai na bayanai kawai. Ba a yi nufin amfani da shi azaman shawarar gyara ba kuma ba mu da alhakin duk wani mataki da za ku ɗauka a kan kowane abin hawa. Duk bayanan da ke wannan shafin ana kiyaye su ta haƙƙin mallaka.
