96 Grand Am - Incomplete Monitor - Catalyst

[slundy]

My mom's 96 recently went to get emission tested and failed. The code was P0440, which means a leak in the gas vapor system. That's easy enough, but the other code was "Incomplete Monitor - Catalyst". I recently replaced the O2 sensor so I had to disconnect the battery, and I'm thinking it hasn't been driven enough to go through all the 'drive cycle' tests, one of which I'm guessing includes testing the catalytic converter?

any help is greatly appreciated.



*EDIT*

Ok that's weird, I was in the grand am section, and it posted this in the cutlass section.

There is a specific drive cycle to reset the emissions monitors, google it or ask an inspection station to print it out for you.
