Default 2005 Lexus - Check Engine/VSR Light on - Error P0403

My wife has a 2005 R330, 150,000+ miles, and has had very few problems with the car.
Today, the check engine light came on and also a VSR light. I have a Ford F150 SuperCrew Truck and have had a few issues with coils. So, I bought a SeekOne SK860 OBD2 Reader to help me when I had truck issues. Well, today I used it on her Lexus and come up with the code P0403 Exhaust Gas Recirculation Circuit Malfunction.
The car runs good and smooth and this is the first time this code has occurred.
Any idea what this code means and what to look for to correct it?
Thanks!
