You have to repair the cause of the computer turning the light on. Then you can turn the light off with a scan tool, or with a battery disconnect.
To reset the check engine light on a 1991 Toyota Previa, you can disconnect the negative battery terminal for about 10-15 minutes. This will clear the engine codes and reset the light. Alternatively, if you have access to an OBD-I scanner, you can use it to clear the codes directly. Make sure to address any underlying issues that caused the light to activate before resetting.
You will need to go to a repair shop and have them scan for codes. That will tell them the problem and when it is repaired they can reset the light.
