The “Service Engine” light illuminating on the instrument panel could be the first warning sign of engine problems. Unless your car doesn’t run at all, contact your auto shop as soon as you can to schedule a diagnostic test on your engine. It could be something easy to fix (such as replacing the gas cap), or it could be something more serious. With the use of a specialized computer, your mechanic can pinpoint what is happening under the hood. Potential problems can be diagnosed early before they turn into a major engine repair.

So why does the “service engine” light come on? Here are five of the most common reasons that this light comes on:

  1. Damaged Gas Cap – If the gas cap is loose or cracked, fuel vapors leak out and can throw the whole fuel system off, reducing gas mileage and increasing toxic emissions.
  2. Faulty Oxygen Sensor – The oxygen sensor monitors the unburned oxygen from the exhaust, and how much fuel is burned. A faulty sensor cannot send the right data to the computer. Fuel efficiency is reduced and toxic emissions are increased.
  3. Failing Catalytic Convertor – The catalytic convertor reduces exhaust gases by converting carbon monoxide and other harmful materials into harmless emissions. When it fails, gas mileage decreases and your car has lost the power to accelerate.
  4. Faulty Mass Airflow Sensor – The mass airflow sensor tells the car's computer to add the proper amount of fuel based on the air coming through to the engine. When this sensor fails, possibly form a clogged air filter, three things can happen; toxic emissions increase, your car will start to stall, and gas mileage decreases.
  5. Dirty Spark Plugs and Wires – The spark plug seals the combustion chamber and provides a gap for a spark to jump across and initiates combustion in your engine. Bad spark plugs will misfire, affecting performance. Damage can also occur in the catalytic converter due to incomplete combustion.

Remember: By taking care of recommended vehicle maintenance service items, you are taking care of your car and possibly preventing a major and costly engine repair.
