how long do you have to drive around before a car inspection
However there is more to it than simply turning it off. By the way the easiest way to turn off the check engine light would be to disconnect the battery for 30 seconds. Inorder to pass inspection your car needs to complete a full drive cycle so that all (8) internal monitors have a status of Ready. If any of the (8) monitors have a status of Incomplete that means you have not yet completed a full drive cycle and you need to drive your car around more.
