What's the "drive cycle" for my vehicle?

(2002 Ford Escape)
in Palatine, IL on June 30, 2010
Just had the EGR valve replaced. Took vehicle into the Illinois EPA emissions testing facility. They rejected me because I hadn't driven the vehicle for one "drive cycle" They couldn't tell me what that involved and referred me to my owner's manual - no info in there. The shop that did the repair said "drive it for 100 miles - IL EPA said that wouldn't work. A local Ford dealer service representative said, "drive it for a week.

Does anyone actually know what a "drive cycle" is? Or is this some generic term that doesn't have a real-world definition (i.e. - a bunch of B.S.)?

Timing is everything, my plate registration expires tomorrow and I can't get a new sticker without passing the IL EPA test. Yeah , I did take the car in for service as soon as the "check engine light" came on, that was 5 days ago and I just got it back today (that's a whole other story. . .).

I love government regulations?

drive cycle is a very specific way of driving your car to run the monitors. chances of you driving and setting them is about 1 in a hundred. let a shop do it. it will be done in about an hour and move on with your inspection.

So, apparently, this is a deep, dark mystery that mere mortal are incapable of comprehending? In fact, it' so mysterious that the vehicle-specific definition is not published anywhere or available to the common fool?

Just wondering. . .
