The problem which caused the check engine light to come on must be diagnosed and repaired on your 1999 Toyota Corolla in order to turn the light off and keep it off. Please see the RepairPal article on the check engine light for more information, here is the link - http://repairpal.com/check-engine-light.
You can use scanner,to turn off the light. (OBD-2 ) However,if there is a code,or problem,the light will come back on. Have you had the car scanned for TROUBLE CODES???
