如何检测发动机电子控制系统的故障

摘要

发动机电子控制系统一般由传感器,控制单元、执行器三部分组成,出现故障后,自诊断系统会记录故障的大概范围,但故障部位还得靠维修人员去检测,才能排除故障,那么在查找故障部位时,维修人员怎样才能检测发动机电子控制系统的故障部位.%Electronic engine control systems are generally composed of sensors,control units, actuators,composed of three parts, after the failure,self-diagnostic system will record the range for failure, but failure to maintenance personnel have to rely on site inspection, to troubleshooting, then find the fault parts, the maintenance personnel how to detect electronic engine control system fault location.
