Is there a reset button to keep the check engine light off on 97 Ford Aerostar van?

There is no reset button to keep the check engine light off on a 1997 Ford Aerostar van, or on any other vehicle. The check engine light is designed to alert the driver to a potential problem with the vehicle's engine or emissions system. It should only be turned off after the problem has been diagnosed and repaired. If you simply turn off the check engine light without addressing the underlying problem, it could lead to more serious damage to your vehicle.
