Yanayin zafin mai yayi yawa

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 (Dodge, Ram, Ford, GMC, Chevrolet, VW, Toyota, da sauransu). Kodayake gabaɗaya, takamaiman matakan gyara na iya bambanta dangane da alama / ƙirar.

Na gano cewa lokacin da motar OBD II ta adana lambar P0168, yana nufin cewa tsarin sarrafa wutar lantarki (PCM) ya gano siginar wutar lantarki daga firikwensin zafin mai / firikwensin abun da mai ko kewaye wanda ke nuna yawan zafin mai.
