Fuel Pressure Regulator (Fuel Rail Pressure Sensor)
WARNING: This page is about a different variant/trim than selected.
The fuel pressure regulator is located in the rear of the fuel rail assembly. The fuel pressure regulator provides the engine control module (ECM) an indication of the actual fuel rail pressure. The ECM uses this information to regulate the fuel pressure, by commanding the fuel pressure regulator 1 and the fuel pressure service valve to obtain the desired fuel pressure
