Maɓallin Kulawa Mai Aiki / Aiki (Banki 1)
Wannan Lambar Matsalar Bincike (DTC) cikakkiyar lambar watsawa ce ta OBD-II. Ana ɗaukarsa ta duniya kamar yadda ta shafi duk kera da ƙirar motoci (1996 da sabuwa), kodayake takamaiman matakan gyara na iya bambanta dangane da ƙirar.
Menene ma'anar lambar matsala P0638?
Wasu sabbin motocin an sanye su da tsarin tuƙi-ta-waya inda na'urar firikwensin ke sarrafawa ta hanyar firikwensin akan bututun iskar gas, tsarin sarrafa wutar lantarki / tsarin sarrafa injin (PCM / ECM), da motar lantarki a cikin maƙasudin.
PCM / ECM yana amfani da Sensor Matsayin Maɗaukaki (TPS) don saka idanu kan ainihin matsayin maƙasudin, kuma lokacin da ainihin matsayin ya ƙare tare da inda aka nufa, PCM / ECM ya saita DTC P0638. Bankin 1 yana nufin gefen silinda lamba ɗaya na injin, duk da haka yawancin motocin suna amfani da gaɓa ɗaya ga duk silinda. Wannan lambar tana kama da P0639.
Yawancin irin wannan bawul ɗin malam buɗe ido ba za a iya gyara shi ba kuma dole ne a maye gurbinsa. Jikin maƙogwaron yana yin ruwa don a buɗe shi a yayin da injin ya lalace, a wasu lokutan maƙasudin ba zai amsa cikakken gazawa ba kuma abin hawa zai iya tuƙa kawai cikin ƙarancin gudu.
