It occasionally requires a moment for the computer to cycle out the error code after the initial issue has been resolved.
Your car’s computer systems run in an ongoing cycle. It could take some time for the computer system to update its “current condition” after you address the issue that was triggering the check engine light. When it does, the diagnostic will realize there is no longer a problem to flag, and the light will turn off.
Try this approach by using your car as usual for up to three days. If the issue still exists, you will need to either try one of the additional methods mentioned below or bring your car to an auto shop like Highland Tire so that a mechanic can identify the problem.
Please remember that if your check engine light is blinking rapidly, you may have a significant problem right away and shouldn’t continue driving.
