Fuel Rail Pressure Sensor - Dual (if equipped)

WARNING: This page is about a different variant/trim than selected.

The dual fuel rail pressure sensor contains fuel pressure regulator 1 and fuel pressure regulator 2 and is located in the rear of the fuel rail assembly. The dual fuel rail pressure sensor provides the 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 to obtain the desired fuel pressure.
