in Nashville, TN because it wasn't ready. My battery died and a new one was replaced and I didn't drive much after that due to a broken ankle. I need to know how much I need to drive for all "readiness monitors" at be set to ready before I return for another emission test. Thank you.

2000 Ford Escort Question: What is the drive cycle for the above car? I didn't pass the emission testing

The ford drive cycle is fairly lengthly, but the following routine should set all monitors in one - three sessions. Gas tank should be around half full, and do this in the morning before outside temperature gets too warm. avoid quick acceleration, sharp turns, fast braking, etc that would slosh the fuel in tank. plan your route ahead of time. The engine cannot be turned off during test.
start engine and idle for one minute
turn air conditioner on for 1 minute
apply brake and slowly shift through all gears ending in park (20 seconds)
drive at 15 mph for 1/4th mile
accelerate smoothly to posted residential speed for 1/2 mile
access a highway and drive 45 mph for 1 mile
remove your foot from gas pedal and coast to around 5 mph and pull over
put transmission in park and wait one minute
shift back to drive, enter roadway, and accelerate at one third throttle until posted speed is acquired
drive for one mile then slow down to 30 mph below posted speed
accelerate at 3/4 throttle to posted speed and drive at posted speed for a couple miles
drive in city stop and go traffic for ten miles
the engine should by now be at operating temp
go home and park the vehicle overnight
The monitors might set in one drive cycle, but go to an Autozone parts store to have the monitors checked for free to verify they have run and completed

Thank you for your answer. Yes, it is fairly lengthly but as long as it works - I'll be happy. Keeping my fingers crossed....

You are very welcome! The Ford drive cycle is actually longer than the revised one provided, but this one works for many vehicle makes and models including Ford, Lexus, and Dodge. It is better if the engine is cold when starting the drive cycle, so the computer can check the engine warm-up time for proper fuel delivery.
Best of luck.
