Fuel Pressure Regulator Control Solenoid Valve

When coolant temperature exceeds 221°F (105°C) or intake air temperature exceeds 176°F (80°C), pressure regulator control (cut-off) solenoid valve shuts off vacuum to fuel pressure regulator. This ensures high fuel pressure to injectors and prevents vapor lock.
