How to Replace an Oil Pressure Sensor on Most Cars

内燃机依靠to function. Pressurized engine oil is used to create a layer between moving parts. This layer of protection keeps moving parts from coming into contact with each other. Without this layer between the moving parts, excess friction and heat are generated.

简而言之,石油旨在提供作为润滑剂和协助冷却的保护。提供此加压,该发动机具有一个油泵,该机油泵拾取了存储在油底壳中的油,累积了压力,并通过发动机组件中的油廊将现已加压的石油运送到发动机内部的几个位置。

The ability of the oil to perform these functions diminishes for several reasons. An engine heats up while running and cools down when shut off. This heat cycle will cause the oil to lose its ability to lubricate and cool the engine over time. As the oil begins to break down, it creates small particles that can clog the oil galleries. This is why the oil filter is tasked with pulling those particles out of the oil and why there are intervals for changing the oil.

在很小的程度上,油压传感器仪表/光可用于将上油系统的健康状况告知驾驶员。随着油开始分解,油压有可能降低。油压传感器检测到这种压降,并在仪表板上传递到仪表或警告灯。旧机械机器对油压万博亚洲客户端的经验法则为每1000 rpms的油压10 psi。

本文将介绍如何更改大多数车辆的油压传感器。不同的车辆制造商和型号之间的差异很小,但是本文的编写方式应该可以适应工作来完成工作。

第1部分:更换油压传感器

需要的材料

油压传感器安装在发动机打击中

步骤1:找到油压传感器。油压传感器最常安装在发动机块或气缸盖中。

该职位没有真正的行业标准,因此传感器可以安装在任何数量的位置。如果您无法找到油压传感器,则可能需要咨询维修手册或咨询专业维修技术人员。

机械拔下油压传感器

步骤2:拔下油压传感器电连接器。Release the retaining tab on the electrical connector and gently pull the connector out of the sensor.

由于油压传感器暴露于引擎盖下的元素,因此随着时间的流逝,碎屑会在插头周围积聚。可能有必要将插头推入并拔出几次插头以释放它,同时脱离固定器。

  • Note:在某些情况下,少量喷雾润滑油可以帮助卸下电连接器。您也可以使用小螺丝刀轻轻撬起连接器。卸下电连接器时,请注意不要损坏电连接器。

用插座卸下油压传感器的机械师

Step 3: Remove the oil pressure sensor。使用适当的扳手或插座,松开油压传感器。

一旦松开,就可以手动将其拧开。

步骤4:将替换油压传感器与已移除的替换油压传感器进行比较。This is all determined by the internal construction, but the physical dimensions should be the same.

Also, be sure the section that threads in is the same diameter and has the same thread pitch.

  • 警告:因为将油压开关安装到将加压油加压的位置,因此通常必须具有某种类型的螺纹密封胶。可以使用几种不同类型的密封胶,并且可以使用许多液体,糊状和磁带。只需确保使用与石油基产品兼容的产品。

Step 5: Install the replacement oil pressure sensor。Thread the replacement into place by hand until you can no longer turn it by hand.

用适当的扳手或插座完成拧紧它。

Step 6: Reinstall the electrical connector。确保连接器座椅完全座椅,并订入“固定”选项卡。

Step 7: Check for proper operation。启动发动机并检查,以确保量规上有油压,或者油压警告灯熄灭。

  • 警告:油压可能需要5-10秒才能恢复。这是因为卸下油压传感器将使需要清除的系统少量空气。如果这段时间未观察到油压,或者未熄灭,请立即关闭发动机。另外,如果在此期间有任何奇怪的声音,请关闭引擎并咨询专业人士。

没有适当的油压,发动机将失效。这不是问题,而是何时的问题,因此请确保立即有效地进行此修复。如果您在任何时候都可以觉得可以用手更换车辆中的油压传感器, contact one of YourMechanic’s certified professional technicians to perform the repair for you.
