What does it mean if my “check engine” or “service engine soon” light comes on?


There are many sensors and computerized components that manage your vehicle’s engine performance and emissions. When one of these fails, the “check engine” light is illuminated. Although your car may seem to run fine, it is important to have the issue addressed to prevent long-term problems or failure of emission tests.

The simplest way to handle this situation is to visit Nolan Motors, Balbriggan where our trained mechanics will read the memory to see what fault the computer is reporting. The best thing about the “Check Engine” light is that it often detects little problems before they become big, expensive problems. Not every problem gives you obvious indications like you get with such things as hard starting, rough running, stalling, etc. That’s why it is very important not to ignore this little light. The “Check Engine” light alerts you to problems like poor fuel mileage, reduced performance or excessive exhaust emissions.

It is important to discuss any concerns you may have. Contact Nolan Motors, Balbriggan if you need help diagnosing and repairing a problem that’s turned on your Check Engine light or Service Engine soon light.
