I just need to know how to fix them. They deal with the EVAP system. I do not know what that is.

I believe the Evap canister is located above/near the gas tank.The pcm commands the vent valve (solenoid) to open or close.I can't tell you how to fix it. May have to use a Tech II like the dealer has to see if it functions properly.
The PO552 code isn't listed in my Helms manual. It is listed in the Autotap manual "Power Steering Pressure Sensor Circuit Low Input".
