Service Engine Soon/ Check Engine light signifies your vehicle 's computer that sees a problem with the emission control system that may or may not exhibit drivability related problems. A 16 pin diagnostic socket under the dashboard that stores valuable information in diagnosing the problem. The computer in your car stores codes indicating what are the problem lies and live sensor values and information.
