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 masarufi, gami da amma ba'a iyakance su zuwa Nissan, Mitsubishi, Mazda, Subaru, Toyota, VW, da dai sauransu Kodayake na asali, takamaiman matakan gyara na iya bambanta dangane da alama / samfurin.
Ana amfani da firikwensin iskar oxygen tare da kayan dumama a cikin injunan zamani. Zafafan firikwensin iskar oxygen (HO2S) abubuwan da PCM (Module Control Module) ke amfani da su don gano abubuwan da ke cikin iskar oxygen a cikin tsarin shaye-shaye.
PCM yana amfani da bayanai daga Bankin 1, HO3S # 2, da farko don saka idanu kan ingancin mai juyawa mai canzawa. Wani sashi na wannan firikwensin shine sinadarin dumama. Ganin cewa a cikin motoci kafin OBD II, firikwensin oxygen ya kasance firikwensin waya guda ɗaya, yanzu galibi sune firikwensin waya huɗu: biyu an sadaukar da su ga firikwensin oxygen kuma biyu an sadaukar da su ga kayan dumama. Mai hura wutar firikwensin oxygen yana rage lokacin da yake ɗauka don isa madaidaicin madauki. PCM yana lura da lokacin da za a kunna hita. PCM ɗin kuma yana ci gaba da lura da da'irar hita don ƙarancin wutar lantarki ko, a wasu lokuta, har ma da na yau da kullun.
Ana sarrafa mai hura iskar oxygen a ɗayan hanyoyi biyu, dangane da alamar abin hawa. (1) PCM yana sarrafa wutar lantarki kai tsaye zuwa mai hita, ko dai kai tsaye ko ta hanyar relay na firikwensin oxygen (HO2S), kuma ana ba da ƙasa daga motar gama gari. (2) Akwai fuse batirin 12 volt (B +) wanda ke ba da 12 volts zuwa kayan dumama a duk lokacin da aka kunna wuta, kuma direba a cikin PCM wanda ke sarrafa gefen ƙasa na kewaye mai hita. ... Fahimci wanda kuke da shi yana da mahimmanci saboda PCM zai kunna hita a ƙarƙashin yanayi daban -daban.
Idan PCM ya gano babban ƙarfin lantarki mara kyau akan da'irar hita, P0044 na iya saitawa. Wannan lambar tana aiki ne kawai da rabin iskar iskar iskar oxygen.

- Buɗe a cikin Circuit Control Heater (12V PCM Controlled Systems)
- Gajera zuwa B + (ƙarfin baturi) a cikin tsarin sarrafa wutar (tsarin sarrafa PCM 12V)
- Buɗe Circuit Ƙasa (12V PCM Controlled Systems)
- Gajewa zuwa ƙasa a cikin tsarin sarrafa mai hita (akan tsarin tushen PCM)
Matsaloli masu yuwu
Na farko, yi duba na gani na injin HO2S na uku a bankin 1 da kayan aikin wayoyin sa. Idan akwai lalacewar na'urar firikwensin ko wata lahani ga wayoyin, gyara shi yadda ake buƙata. Bincika wayoyin da aka fallasa inda wayoyi ke shiga firikwensin. Wannan yakan haifar da gajiya da gajerun da'ira. Tabbatar cewa an kawar da wayoyin daga bututu mai shaye shaye. Gyara wayoyi ko maye gurbin firikwensin idan ya cancanta.
Idan yayi kyau, cire haɗin bankin 3 # 1 HO2S kuma tabbatar cewa 12 volts B + yana nan tare da injin kashe (ko ƙasa, dangane da tsarin). Tabbatar da'irar sarrafa dumama (ƙasa) ba ta cika. Idan haka ne, cire firikwensin O2 kuma bincika shi don lalacewa. Idan kuna da damar halayen juriya, zaku iya amfani da ohmmeter don gwada juriya na ɓangaren dumama. Juriya mara iyaka yana nuna buɗaɗɗen kewaye a cikin hita. Sauya firikwensin oxygen idan ya cancanta.
Tattaunawar DTC mai dangantaka
- 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 p0044?
Idan har yanzu kuna buƙatar taimako tare da DTC P0044, 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.
