故障现象一辆行驶里程为6万多km的2006款起亚赛拉图轿车,发动机怠速熄火。故障诊断根据故障现象,初步判断是怠速控制阀堵塞或损坏,拆下怠速控制阀并清洗调整后,车辆依旧怠速熄火,更换怠速控制阀后故障有所好转,车辆能够起动怠速运转,但怠速不稳,车辆有明显抖动,这说明该车故障和怠速控制阀关系不大。分别检查该车燃油系统和点火系统,都没有问题;用故障检测仪检测,读到故障代码P0016,显示的故障内容为“凸轮轴/曲轴位置相关性”。
Symptom A mileage of more than 60,000 km 2006 Kia Cerato sedan, the engine idling stop. Troubleshooting According to the fault phenomenon, the initial judgment is that the idle speed control valve is clogged or damaged. After the idle speed control valve is removed and cleaned and adjusted, the vehicle still idles off.
