Q: Can a purge solenoid cable cause a EVAP leak code?

asked bySeptember 29, 2016

我有P0455,P0456和P0457代码,但没有破裂的软管,气体的气味来自阀门。

嗨,谢谢您的问题。当发动机关闭时,排气关闭阀和罐清除阀将关闭。燃料无法逃脱到大气中。当发动机启动时,罐上的清除阀打开,以使被困的燃料蒸气通过发动机真空吸收到进气歧管中。同时,通风闭合阀也打开,以使少量空气进入罐子并与燃油蒸气混合以获得更好的混合物。一旦排气,储罐中的压力传感器显示出明显的下降,两个阀门再次关闭系统。当该电磁阀电缆无法提供适当的连续性时,这不允许系统的通风尽可能地发生。这就是导致EVAP泄漏代码的原因。
