Bayanan Bayani na OBD-II
Ƙananan siginar siginar a cikin keɓaɓɓen keɓaɓɓen keɓaɓɓen kula da bawul ɗin shaye -shaye (Bank 2)
Mene ne wannan yake nufi?
Wannan lambar ita ce lambar ikon wutar lantarki ta OBD-II, wanda ke nufin ya shafi duk kera da ƙirar abin hawa (1996 da sabuwa), kodayake takamaiman matakan gyara na iya bambanta dangane da ƙirar.
A kan motocin da aka sanye da tsarin canjin lokaci mai canzawa (VVT), injin sarrafa injin / tsarin sarrafa wutar lantarki (ECM / PCM) yana lura da matsayin camshaft ta hanyar daidaita matakin mai na injin tare da sarrafa madaidaicin matsayin camshaft. Ana sarrafa madaidaicin iko ta siginar da aka daidaita (PWM) daga ECM / PCM. ECM / PCM yana lura da wannan siginar kuma, idan ƙarfin lantarki yana ƙasa da ƙayyadaddun bayanai, yana saita wannan DTC kuma yana haskaka Lamp Indicator Malfunction (MIL).
Bank 2 yana nufin gefen injin da ba ya ƙunshi silinda #1 - tabbatar da duba daidai da ƙayyadaddun masana'anta. Solenoid mai sarrafa bawul ɗin shaye-shaye yawanci yana kan mashigin shaye-shaye na kan Silinda. Wannan lambar tayi kama da lambobin P0084 da P0086. Wannan lambar kuma tana iya kasancewa tare da P0029.

Kwayar cutar na iya haɗawa da:
- Lambar Alamar Rashin Aiki (MIL) ta haskaka
- Hanzari mara kyau
- Rage tattalin arzikin mai
Dalili mai yiwuwa
Dalili mai yiwuwa na DTC P0085 na iya haɗawa da:
- An gajartar da kayan aikin wayoyi zuwa ƙasa
- Ƙarancin lantarki zuwa ƙasa
- ECM mara lahani
Matakan bincike
Waya Harness - Cire haɗin masu haɗa kayan aiki daga PCM/ECM ta amfani da zane na wayoyi, gano wurin + da - wayoyi zuwa solenoid. Ana iya fitar da solenoid daga gefen ƙasa ko daga gefen wutar lantarki, dangane da aikace-aikacen. Koma zuwa zane-zane na masana'anta don tantance wutar lantarki a cikin kewaye. Yin amfani da na'urar voltmeter na dijital (DVOM) da aka saita zuwa saitin volts, duba ƙarfin lantarki akan ingantacciyar wayar baturin abin hawa da maras kyau waya akan kowace waya zuwa solenoid mai sarrafawa. Dangane da aikace-aikacen, idan solenoid ya kasance ƙasa zuwa chassis, duba wayar wutar lantarki zuwa solenoid mai sarrafawa a cikin kayan aikin wayar PCM/ECM, kada a sami ƙarfin lantarki. Idan ƙarfin lantarki yana nan, duba ɗan gajeren zuwa ƙasa a cikin wayoyi zuwa solenoid mai sarrafawa ta hanyar cire haɗin haɗin haɗin da komawa zuwa solenoid.
Sarrafa Solenoid - Bincika ɗan gajeren ƙasa ta hanyar solenoid mai sarrafawa ta hanyar haɗa jagora ɗaya na DVOM zuwa sanannen ƙasa mai kyau da ɗayan zuwa kowane tasha akan solenoid mai sarrafawa. Idan juriya tayi ƙasa, ana iya gajarta solenoid a ciki.
PCM/ECM - Idan duk wiring da iko solenoid yayi kyau, zai zama dole a saka idanu akan solenoid yayin da injin ke gudana ta hanyar duba wayoyi zuwa PCM/ECM. Yin amfani da kayan aikin bincike na ci gaba wanda ke karanta ayyukan injin, saka idanu da zagayowar aikin da solenoid mai sarrafawa ya saita. Zai zama dole don sarrafa solenoid yayin da injin ke gudana a cikin sauri da lodi daban-daban. Yin amfani da oscilloscope ko multimeter mai hoto da aka saita zuwa zagayowar aiki, haɗa waya mara kyau zuwa sanannen ƙasa mai kyau da ingantaccen waya zuwa kowane tashar waya akan solenoid kanta. Ya kamata karatun multimeter ya dace da ƙayyadadden zagayowar aiki akan kayan aikin dubawa. Idan sun saba, ƙila za a iya juyawa polarity - haɗa ingantaccen waya a ɗayan ƙarshen waya zuwa solenoid kuma maimaita gwajin don dubawa. Idan ba a sami sigina daga PCM ba, PCM kanta na iya yin kuskure.

- A halin yanzu babu batutuwa masu alaƙa a cikin dandalin mu. Sanya sabon taken akan dandalin yanzu.
Kuna buƙatar ƙarin taimako tare da lambar ku ta p0085?
Idan har yanzu kuna buƙatar taimako tare da DTC P0085, 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.
