P0458 = Evaporative Emission System Purge Control Valve Circuit High

You have to replace your "Leak Detection Pump". When the solenoid within this pump is not active, it throws this code.

A Leak Detection Pump is a small air pump. It pressurizes the EVAP & Fuel system to make sure there are no leaks. This ensures that no harmful vapors are escaping to the atmosphere. It is used by the PCM. This is actually a pretty small pump and doesn't have a lot of pressure behind it so they do fail pretty easily. And....this is a part of the emissions system, so yes...It can make you fail your state inspection.
