Some of these monitors need several drive cycles to run. A drive cycle starts when the vehicle is cold. If you hopped in the vehicle while it was still warmed and drove hundreds of miles, NOTHING was gained. Let the vehicle sit over night, make sure the fuel level is above 1/4 and below 3/4 (allows the EVAP monitor to run) and drive several miles (around 20) letting it warm up in the process and vary the type of driving (accelerating, long decel, steady cruise, etc...) and also vary your speed (few miles at 25 mph, few miles at 40 mph, again at 60 mph, etc...) You may need to repeat this process over a few days. This type of stuff normally occurs during everyday driving, assuming you live far from work. Also keep in mind that if you have an issue with the battery dying, the monitors reset every time the battery is disconnected or you need a jump start.
