Bayanan Bayani na OBD-II
Babban siginar siginar a cikin keɓaɓɓen keɓaɓɓen keɓaɓɓen kula da bawul ɗin shaye -shaye (Bank 1)
Mene ne wannan yake nufi?
Wannan lambar ita ce lambar ikon wutar lantarki ta OBD-II, wanda ke nufin ya shafi duk kera da ƙirar abin hawa (1996 da sabuwa), kodayake takamaiman matakan gyara na iya bambanta dangane da ƙirar.
A kan motocin da aka sanye da tsarin canjin lokaci mai canzawa (VVT), tsarin sarrafa injin / tsarin sarrafa wutar lantarki (ECM / PCM) yana lura da matsayin camshaft ta hanyar daidaita matakin mai na injin tare da keɓaɓɓen ikon sarrafa camshaft. Ana sarrafa siginar sarrafawa ta siginar da aka daidaita (PWM) daga ECM / PCM. ECM / PCM yana lura da wannan siginar kuma, idan ƙarfin lantarki ya wuce ƙayyadaddun bayanai, yana saita wannan DTC kuma yana kunna Lamp Indicator Lamp (MIL).
Bank 1 yana nufin gefen # 1 Silinda na injin - tabbatar da duba daidai da ƙayyadaddun masana'anta. Solenoid mai sarrafa bawul ɗin shaye-shaye yawanci yana kan mashigin shaye-shaye na kan Silinda. Wannan lambar tayi kama da lambobin P0078 da P0079. Wannan lambar kuma tana iya kasancewa tare da P0027.
