What's the "drive cycle" for my vehicle? on 2002 Ford Escape

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. . .
