SOURCE: toyota 4 runner fuel pressure
pressuer should actually raise under throttle, but not much. maybe 5psi. 38-44psi is the correct range. if your dropping much I would replace the fuel filter. next I would check the tank for debris or water, finally i would replace the Fuel pressure regulator.

The fuel pressure regulator is on the driver side fuel rail, close to the back of the engine. You need to pull the intake plenum off to access the pressure regulator.
The normal operating fuel pressure is 38 to 44 PSI

You need to reset the light with a scan tool, the same one you used to read the code in the first place.
