“What is the check engine light?” / “What does a check engine light mean?”

The check engine light, or “CEL,” is part of a vehicle’s on-board diagnostic system, or “OBD.” Computers are constantly monitoring and regulating myriad performance variables and sensors throughout the vehicle. When this electronic control system detects a “fault” or malfunction, it stores this information in the form of diagnostic trouble codes, or “DTC’s” within it’s memory and illuminates the check engine light to alert the driver of the problem. The list of problems that could turn on the check engine light is widely varied and ranges dramatically in terms of severity. To determine exactly what the cause of your check engine light is, you should take your vehicle to a qualified service technician to have the codes “read” and a proper diagnostic performed.
