More a number of drive cycles than miles.

+1 on the above and add lots of gear changes while driving.

Just driving in "D" will take for ever. Manually change up and down several times in say a 5 mile drive.

If you don't get P1111 fairly quickly, read the status of the OBD monitors and concentrate on those unset - using the drive cycle.

And find out WHY the computer reset was done because that's going to be a key item.

This document (near the front) talks about the various drive cycles for different tests, might be worth following these directions.
