电控系统各组成零部件、传感器本身及配线出现故障,是造成电控系统故障的主要原因,因此掌握各组成部分及配线故障对发动机及车辆运行的影响,对于诊断故障时迅速找出故障原因,开阔思路极为重要。本人对电喷发动机进行真实模拟试验、理论分析及参考其它资料,总结出电控系统主要部 Components of the electronic control system components, the sensor itself and the wiring failure, is the main cause of the electronic control system failure, so to master the various components and wiring faults on the engine and vehicle operation, to quickly identify the fault diagnosis Failure reasons, broaden your thinking is extremely important. I EFI engine real simulation test, theoretical analysis and reference to other information, concluded that the main electronic control system
