Default 97 aultima obd 2 code p0400

I had a code of 1400, changed the egr purge valve, drove the car 298 miles, and the engine light comes on. New code po400. What exactly is that, what are they referring to?

This is an EGR code for flow. Remove the tube from the valve and clean it out

Thanks that did the trick. I took it back to dirty Jersey DMV, for inspection. They didn't have the emissions computer at the re-inspection lane, the checked the entire car again. Failed me for " you may have an exhaust leak".
