The check engine light on a Chevrolet Colorado can be rest by connecting an OBD II code reader to the vehicle's computer . Each of the codes can then be reset which will turn the associated light off.
The check engine light comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, a check engine light is lit when there is a problem in the emissions or somthing that is affecting the effectiveness of the emissions.
There are many sensors that can trip the check engine light to come on.
