I thought the 2002+ had a deleted EGR?
Anyway, I got this code when the tube from the valve to the intake cracked and finally broke. There is a monitor on flow as the computer needs to know how much air is passing for the MAF calculation. It also generated a few "lean" codes before the pipe completely broke in two.
It's hard to see the pipe with the thermal wrap around it. Feel around the pipe while wiggling it to see if you can feel any cracks or breaks.
