OBD-II Lambar Matsala - P0351 - Takardar Bayanai

Ignition coil Rashin nasarar da'ira na farko/secondary.

P0351 babban lambar OBD2 Diagnostic Trouble Code (DTC) ne na yau da kullun wanda ke nuna matsala tare da kunna wuta A.

Menene ma'anar lambar matsala P0351?

Wannan Lambar Matsalar Bincike (DTC) lambar watsawa ce gaba ɗaya, wanda ke nufin ya shafi motocin OBD-II sanye take. Kodayake gabaɗaya a cikin yanayi, takamaiman matakan gyara na iya bambanta dangane da alama / ƙirar.

Tsarin wuta na COP (coil on plug) shine abin da ake amfani dashi a yawancin injunan zamani. Kowane Silinda yana da keɓaɓɓen coil ɗin da PCM (Module Sarrafa Powertrain) ke sarrafawa.

Wannan yana kawar da buƙatun wayoyi masu toshe tartsatsi ta hanyar sanya coil ɗin kai tsaye sama da filogi. Kowane nada yana da wayoyi biyu. Ɗayan shine ƙarfin baturi, yawanci daga cibiyar rarraba wutar lantarki. Wata waya ita ce kebul ɗin direba daga PCM. PCM ta kafa/katse haɗin wannan da'irar don kunna ko kashe coil. PCM ne ke sa ido akan da'irar direba don kurakurai.

Idan an gano buɗaɗɗiya ko gajarta a cikin lambar da'irar direban coil 1, lambar P0351 na iya faruwa. Bugu da ƙari, dangane da abin hawa, PCM na iya ƙin injector ɗin mai zuwa silinda.
