Have you ever been driving down the highway and all the sudden, a faint glow comes from your car's dashboard? You realize that it is your check engine light and you immediately panic. Does this mean you need to go in for a repair on your engine or is it something more minor than that? Many people ask themselves these same questions everyday, so what are some of the main causes for your mysterious check engine light to come on?
CarMD recently collected data on 170,000 vehicles that have been repaired from 1996 to 2010 and examined what are the main reasons for that pesky check engine light to come on. The following is what they found in their analysis:
- Faulty Oxygen Sensor
- A Loose or Non-Existent Gas Cap
- Damaged Catalytic Convertor
- A Mass Air Flow Sensor Malfunction
- Misfiring Spark Plugs
As you can see the reasons for your vehicle's check engine light to go off range from extremely serious issues to minor repairs. The moral of this story is when that check engine light goes off, get your vehicle checked immediately because it is better to be safe than sorry, even if it is a loose gas cap!
