Check Engine Light
Master Automotive Centers can diagnose your code.
The check engine light is part of the onboard diagnostic system, or OBD, and is reserved for problems that may have an effect on the vehicle emissions systems. When the electronic-control system finds a problem it cannot adjust, the OBD turns on a yellow warning indicator and stores a trouble code in its memory. These diagnostic trouble codes (DTC) help identify the source of the problem which can be read with a scan tool or diagnostic computer.
