Hi there. Anytime you have a check engine light on the dashboard, it’s because the computer detected an error picked up by one of the sensors on your car. By having a professional mechanic come to your location and complete a check engine light inspection, you can eliminate a lot of the guess work and ensure the root source of your mechanical problems are correctly diagnosed and the right repairs can be completed.
