Mene ne wannan yake nufi?
Wannan lambar ita ce lambar watsawa gaba ɗaya. Ana ɗaukarsa ta duniya kamar yadda ta shafi duk kera da ƙirar abin hawa (1996 da sabuwa), kodayake takamaiman matakan gyara na iya bambanta kaɗan dangane da ƙirar.
Ana amfani da firikwensin iskar oxygen tare da kayan dumama a cikin injunan zamani. Sensor Oxygen Sensors (HO2S) abubuwan da PCM (Powertrain Control Module) ke amfani dashi don gano adadin iskar oxygen a cikin tsarin shayewa.
PCM tana amfani da bayanan da take karɓa daga bankin 2,2 HO2S da farko don saka idanu da ingancin mai mu'amalar catalytic. Babban ɓangaren wannan firikwensin shine kayan dumama. Ganin cewa motocin kafin OBD II suna da firikwensin oxygen na waya guda ɗaya, yanzu an fi amfani da firikwensin waya huɗu: biyu don firikwensin iskar oxygen da biyu don abubuwan dumama. Na'urar firikwensin iskar oxygen yana rage lokacin da ake ɗauka don isa ga rufaffiyar madauki. PCM tana sarrafa injin dumama akan lokaci. Hakanan PCM yana lura da da'irori masu dumama don ƙarancin ƙarfin lantarki ko, a wasu lokuta, har ma da ƙarancin halin yanzu.
Dangane da abin hawa, ana sarrafa injin firikwensin iskar oxygen ta hanyoyi biyu. (1) PCM kai tsaye tana sarrafa wutar lantarki ga na'ura, ko dai kai tsaye ko ta hanyar iskar oxygen firikwensin (HO2S), kuma ana ba da ƙasa daga wurin gama gari na abin hawa. (2) Akwai fuse baturi mai ƙarfin volt 12 (B+) wanda ke ba da 12 volts ga mahaɗar wuta a duk lokacin da wuta ke kunne kuma direba yana sarrafa injin a cikin PCM wanda ke sarrafa gefen ƙasa na kewayen hita. . Gano wanda kuke da shi yana da mahimmanci saboda PCM zai kunna hita a ƙarƙashin yanayi daban-daban. Idan PCM ya gano babban ƙarfin lantarki a kewayen hita, P0058 na iya saitawa. Wannan lambar tana aiki ne kawai ga rabin da'irar dumama firikwensin iskar oxygen. Bank 2 shine gefen injin da bai ƙunshi silinda #1 ba.
