If your check engine light flashes on, you don’t need to jump to the conclusion that your engine is on the cusp of total failure. But it’s still best to get to the shop ASAP for computerized diagnostics. By being proactive, you’ll have the best chance to identify and resolve the issue before it escalates and becomes more expensive to address. At Absolut Autoworks, our local mechanics provide expert check engine light repair in the greater Sterling, VA area. Here are six common check engine light triggers.

Faulty Catalytic Convertor

Your catalytic converter does the important job of turning harmful compounds in your vehicle’s emissions into safer gasses before they’re sent out into the open air. Warning signs of a failing catalytic converter include dark exhaust smoke, decreased acceleration, and a smell like rotten eggs. 

Failing Spark Plugs

For optimal performance and gas mileage, it’s important that your spark plugs are healthy. Signs of faulty spark plugs include poor acceleration, worsening MPGs, and misfiring.

Bad Mass Airflow Sensor

Healthy MAF sensors help to ensure that fuel is properly injected with air. Signs of MAF sensor trouble include decreasing acceleration, hard starts, and rough idling.

Faulty Oxygen Sensor

Properly-functioning O2 sensors monitor the amount of unburned oxygen in the exhaust system. If you have an oxygen sensor problem, then catalytic converter trouble could follow.

Bad Battery/Charging System

If your battery is faulty, then low voltage at the computer could cause your check engine light to come on.

Gas Cap is Loose/Missing

If your gas cap is loose or missing, the fuel could evaporate before it is directed to your engine for use. So it’s important that you always fully tighten your gas cap after you fill up your tank.
