Fuel Pressure Sensor

A fuel rail pressure sensor is a component which has the ability to reduce evaporative emissions. Since these emissions tend to come through the vehicle, the fuel rail sensor allows the engine just enough fuel so that it can run in the correct way. This is an automotive component that limits the fuel�s ability to get left inside of the fuel line, which can then evaporate and migrate elsewhere. The fuel rail pressure sensor operates by reading the internal pressure of the rail itself. This is how it is able to sense the precise amount of fuel still present inside of the fuel rail. When the sensor detects fuel in the rail, there is an electrical signal that is actuated by the system. This serves to indicate the precise amount of fuel which is needed to power the engine at any given throttle level.
