How many drive cycles does it take to clear a code?

As I discussed earlier, most emissions-related DTCs take at least two drive cycles to set, so it stands to reason it will take at least two passes to turn off the MIL. Keep in mind the second drive cycle will not be complete until you turn off the ignition.
