摘　　要：发动机滑油压力传感器是一种测量供油与回油压差的压力传感器。针对滑油压力传感器输出出现摆动直至无示数的故障现象,建立了故障树对故障原因进行分析定位,并实现了故障现象的复现,验证了故障分析的结论。The engine oil pressure sensor is a pressure sensor that measures the difference between fuel supply and return oil pressure.A fault tree was established to analyze and locate the cause of the malfunction caused by the swing of the output of the oil pressure sensor until there was no indication.The fault phenomenon was reproduced to verify the conclusions of the fault analysis.
