问:检查引擎灯

你好,这段代码与你的蒸发排放系统。你的车有一个小的放气阀称为清洗电磁阀从油箱控制气体的排放这些气体建立内部,尤其是当你加油车。EVAP系统防止油箱的燃油蒸汽泄漏到大气中。EVAP系统收集和临时存储燃油蒸汽活性碳罐。活性碳罐充满了活性炭颗粒能够吸收燃料蒸气。发动机运行时,罐和燃烧的燃料气体清除引擎。排气控制阀(电磁)控制外部空气流的活性碳罐。排气阀由发动机控制电脑(PCM)。通常调压阀是开着的。时关闭发动机电脑测试EVAP系统泄漏。如果检测到泄漏EVAP系统,检查引擎灯将照亮破折号和相关故障代码问题将存储在发动机电脑。 When an air leak is present in the EVAP system, the MAP sensor will not be able to determine the air density, and the MAF sensor will not be able to determine the volume of air, entering the engine correctly. This will lead to an over fueling situation or an under fueling situation depending on the size of the air leak and engine operating speeds and load. This may eventually lead to catalytic converter problems as well as misfiring problems. I would recommend having an expert from Your Mechanic come to your location to diagnose and inspect your vehicle.
