The computer on your Chevy S10 ultimately controls a variety of vehicle functions from air and fuel delivery to generating and storing fault codes. When the computer generates a fault code, it means that there is something wrong with one of the vehicle’s critical systems—typically a sensor related to the emissions control system. This problem needs to be fixed to prevent major damage to the engine and related components. A free diagnostic test can be done by any auto parts store to determine the cause of the problem. After the problem has been fixed, you need to know how to reset the Chevy’s computer.
