You need a scanner capable of resetting the codes, but they will not go away unless they are fixed.
You need to make the repair for it to go away...
Check engine cannot be reset - it requires the offending condition to be fixed. The codes will re-initiate next time the car is run if the condition still exists and the light will come back on. Determine what code is being generated and then find and fix the problem.
