EGR valves are usually activated by a vacuum line from a thermal sensor. It could be leaks in the vacuum lines, a failure of the sensor, or a failure of the valve itself. Since the valve is exposed to the heat of the exhaust system, it is prone to jamming from carbon buildup and destruction of the vacuum diaphragm from heat.

Yes, if the valve is bad. With the car idling, move the EGR valve diaphragm with your fingers. The engine should quit or want to quit. If it doesn't do this, it could be plugged up. Remove the EGR valve and clean any carbon deposits in the valve and also do the same on the engine side where the EGR valve is connected. If the EGR has never been removed before, it will probably have carbon buildup.
