求翻译：电控发动机的故障并非一定出在电子控制系统。如果发现发动机有故障，而故障警告灯并未发亮（未显示故障码），大多数情况下，该故障可能与发动机电控系统无关，此时，就应该像发动机没有装电控系统那样，按照基本诊断程序进行故障检查。否则，可能遇到一个本来与电控系统无关的故障，却检查电控系统的传感器、执行器和电路等，花费了很多时间，而真正的故障反而没有找到。是什么意思？

Electronically controlled engine failure is not necessarily out in the electronic control system. If you find that the engine failure, the failure warning light does not shine (not shown fault code), most cases, the fault may be nothing to do with the engine control system should be like the engine

The electrically controlled engine breakdown is by no means certain in the electronic control system.If discovered the engine has the breakdown, but the breakdown tell-tale light shines by no means (had not demonstrated breakdown code), in the majority situations, this breakdown possibly has nothing

Faults are not necessarily out of electronic control engine electronic control system. If you find that engine failure and fault warning light does not shine (not display fault codes), in most cases, the fault is likely has nothing to do with the engine electronic control system, at this point, shou
