The oil sensor measures the pressure on the oil inside the engine of the car. Oil pressure is essential to a well-running car, to ensure it is clean, cool and well lubricated.Continue Reading
Located on the side of the engine block, the oil sensor taps into the oil circuit in the engine, gauging the oil pressure. When the gauge light on the dash comes on, it means the oil pressure is outside the manufacturer's recommended limits. This could be either because there isn't enough oil inside the engine, or that there isn't enough oil circulating in the circuit to keep everything running smoothly. The light may come on because of ordinary wear and tear on the engine over time as parts come loose, causing shifts in the oil pressure. The oil sensor light may also come on if the gauge is disrupted by dirt.
Motor oil is essential to cooling, lubricating and cleaning the car's engine. For it to perform all these functions, the oil must be kept under pressure. This ensures that the oil isn't swept away with the engine's force and ensures that the oil keeps moving to cool the car. Those who have problems with oil pressure need to get it fixed before continuing to drive the car, as driving it with pressure that is outside the recommended range can be dangerous.Learn more about Engine Oil
