When your Check Engine light comes on, do you react with utter panic or do you just want to ignore it and hope it goes away? Maybe you react both ways. That same Check Engine light could come on for anything from a serious engine or transmission problem all the way down to a loose gas cap.
So how do you determine if it’s an emergency or not? If the light is flashing or red you will need to get your vehicle to a repair shop ASAP to prevent catalytic converter or other damage! If the light is not flashing, you will still want to get your vehicle in to a repair shop to determine why the light is on, but you can still drive until your appointment.
The mechanic will connect a “scan tool” to your vehicle’s on board diagnostic system. The scan will tell the technician the cause of your problem or it may require further testing to pinpoint the exact cause of the problem.
Once the problem is determined, the repairs are made and the Check Engine light is reset. Problem solved!
