You have electronic power steering? What is year--make--model? I'd look at the wiring diagram and check the basics, voltage and ground. Checking the fuse is good, but, use a test light and check voltage on fuse circuit. Some fuses hot all the time, some go hot with the key on.
Any related trouble codes for power steering?

loose mud flaps
loose air dam plastic plate under front of car
something stuck under car
faulty drive belt on engine

This is what I found.

What make , model an year vehicle ?

Your vehicle has electronic throttle control , the cruise control switches are an input to the PCM - engine computer , there is a DC electric motor on the throttle plate the computer use to control the speed . If you do not have factory service repair info and a professional type scanner , your best would be to take it to the dealer .

This code has nothing to do with the purge valve . Evap vent valve . Has nothing to do with intake manifold.
An intermittent condition could be caused by a damaged EVAP vent housing, a temporary blockage at the EVAP canister vent solenoid valve inlet, or a pinched vent hose. A blockage in the vent system will also cause a poor fuel fill problem.
• An EVAP canister, vent hose or vent solenoid valve that has restricted flow may cause this DTC to set. Using purge solenoid valve command with a scan tool will allow vacuum to be applied to the system instead of pressure. With the EVAP canister vent solenoid valve open and the EVAP canister purge solenoid valve commanded to 100 percent, vacuum should not increase to more than 9 inches H2O.
Your best bet , take it to a qualified repair shop.
