Your light is on for a reason. DO NOT IGNORE IT! It could lead to major costs. Go to Advance auto parts and ask them to code it out, it's free. Then post the code number.
Your check engine light is likely caused by an evaporative emissions system issue if you are not experiencing any driving problems. Check your fuel cap to make sure it is secure fully first. This will set the light on if it is loose. Yes, you can try a parts store to give you a free code scan, but nothing can replace a quality relationship with a technician that can actually help you.
