问：零的油压计。没有泄漏，有很多油。没有异常的噪声和温度正常。没有低压警告灯。

当可能发生一些事情时，机油压力表通常会下降。要么电动机实际上在油上很低，因此油泵可能会发生故障或油压发送单元无法正常工作，可能会产生错误的阅读。如果发动机实际上在油上较低，则可能会注意到由于电动机缺乏足够的油，温度规读数高于正常温度。我建议使用量油尺检查电动机中的实际油位。确保油位达到“完整”标记。如果将其注册为“完整”，那么您可能会有一个机油压力发送单元。Many vehicles also have a safety feature built into the vehicle’s computer system which will shut the engine down completely or trigger a “safe mode” of some kind which will drastically limit the vehicle’s engine power to avoid further engine damage until the oil pressure problem is corrected. I would recommend having an expert from YourMechanic come to your location to take a look at your vehicle to determine what may be causing your oil pressure to be so low.
