Why not buy a cheap tool to clear the Check Engine/Service Engine Soon indicator or wait for it to go away?
The Check Engine/Service Engine Soon indicator is connected to the engine controller, which constantly determines if a sensor or actuator is faulty. Even if you did reset this indicator, or wait for it to be cleared on its own, this is an indication that something is failing or has failed. It’s unwise to pretend that the indicator didn’t light. You could be causing more system damage and potentially strand yourself on the side of the road and/or cost you a lot more money, because you ignored it or waited until it was too late to service the vehicle. You need the assurance that your vehicle is in good working order. Even if the problem is trivial, it could lead to other problems that could cost you money.
