Question about Cars & Trucks
Fuel Pressure Regulator Control Solenoid
Since the code came back immediately this indicates that it is a hard fault. The solenoid is an electrical switch controlled by the ECM. In this case it controls vacuum provided to the fuel pressure regulator. On this vehicle locate the fuel injectors and the rail above them. At the end of the rail is the regulator which on it should have a vacuum hose. Check out the hose make sure there is not leaks or it is not coming apart. If it is okay the other end of it plugs into the solenoid. This is the failed component.
