Product description

The Oil Pressure Sensor is a simple device that activates a warning light on the dashboard when the engine's oil pressure does not meet a set level. This is a very simple device consisting of a spring switch and a diaphragm. The diaphragm receives the oil and is designed to remain open at a set pressure level. Pressure pushes the diaphragm into the switch and keeps the warning light off. If the pressure level is not reached, then the switch will trigger the light on the dashboard. In general, oil pressure sensors are designed to identify low oil pressure, not high oil pressure. Too low oil pressure can cause serious damage to the engine, which can be caused by a blocked oil filter, a malfunctioning oil pump, or other causes. The oil sensor is designed to give you enough warning to shut down your engine before any of these things cause real damage. Most oil pressure sensors are simple switching types that will open the circuit if a minimum oil pressure level is present. Another version is an actual sensor that measures oil pressure. For the switched version, you may see a warning light on the dashboard when the ignition is on, but not when the engine is off. This is because the switch requires oil pressure to open. When the engine starts, the oil pump starts to produce pressure. Once the minimum pressure is reached, the switch turns on and the warning light goes off.
