Fuel Pressure Regulator 2

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

The engine control module (ECM) controls the fuel rail pressure using two pulse width modulated fuel rail pressure regulators. Fuel pressure regulator 2 is located on the end of the fuel rail and meters the amount of fuel being returned to the fuel tank. The ECM varies the pulse width modulated voltage to the fuel pressure regulator 2 to relieve excessive fuel pressure which returns to the fuel tank. When the ignition is Off, fuel pressure regulator 2 opens to bleed off the pressure in the fuel rail.
