No, the check engine light will not shut itself off. It needs to be turned off by a mechanic. If it is on when u go to inspection, your car will not pass
The light could go off on its own if the problem fixed itself and there is anough time for it to pass it's selftests enough time.
The above answer is incorrect. If the computer in the car does not detect the problem which caused the check engine light to illuminate in the first place after a certain amount of cycles the light will turn off and you will be able to pass emissions. Case in point: My '96 Cougar set the check engine light due to some emissions components failing. Specifically, the purge flow sensor. I replaced the part and did not reset the computer. After about 3 days worth of drive cycles the light turned off by itself.
