P0406 is the EGR valve. It sits on the right front of the engine. Just remove the two bolts on the tube and the two bolts on the valve itself and there you go. Reset the lamp with a scan tool or by disconnecting the battery for a couple minutes and retest.

05 ram with hemi code p0406

Most of the times it is the EGR sensor that has gone bad. It is located in the back right side by the throttle body. You will see a hose that runs from the top of your EGR to the sensor. On your Dodge it is VERY eay to replace.
