How much time does it take for the check engine light to turn off?
The light remaining on even after the repair is a concern for many automobile owners. Don’t freak out if you’re having this experience. After the repair, you might believe there is still a problem with the car, but it is only because the light needs some time to reset.
The internal computer of the car only resets after a predetermined interval during which it rechecks all of its sensors. After around 10 to 20 cycles, the reset may occur automatically.
A cycle is a phase in which you start the car and then shut it off once more. Other vehicles require you to go between 50 and 100 miles before the reset occurs.

Clearing the check engine light can cause your car to fail smog
Clearing the check engine light won’t help if you’re trying to pass a smog test. Yes, a car with a lit check engine light will unavoidably fail a smog test. Clearing codes won’t make it pass, though. If you turn off the check engine light and then go for a smog check, the car will fail. Monitors are the intermittent tests that the computer runs. Some tests are run while the car is moving down the freeway. Some tests are run when the car is parked. Some tests require the car to sit while idling. And some tests require all of the above.
If there is nothing wrong with the automobile, clearing the check engine light will work; however, if the monitor runs and passes, the check engine light will turn off by itself and no reset is necessary. Most of the time, there is a problem when the check engine light is on.
When you clear codes, you also clear diagnostic data
A fault code and freeze frame information are both kept when the check engine light comes on. We can identify which computer test failed using a problem code. The data from the freeze frame reveals the information the computer viewed at the time of the error. All of this information is erased when the check engine light is reset. It is harder to diagnose without this information.
New data will be recorded when the check engine light returns, but you never know if it will be as accurate as the initial data. Consider it similar to photographing a bunch of friends. You take a lot since both the good and the bad will be present. Data from freeze frames frequently matches. You examine each snapshot before deleting since you are unsure which one will be the greatest.
