Don’t Ignore It

Did you know that approximately 1 in 10 drivers on the road today are traveling with their vehicle’s “Check Engine” light on?

To help motorists demystify the dreaded “Check Engine” light, Georgia’s Clean Air Force (GCAF) launched the “See the Light” campaign to educate motorists in the 13-county metro Atlanta region on common “Check Engine” light causes and ways to avoid costly vehicle repairs.

Five Most Common Reasons For the “Check Engine” Light to Illuminate

  1. The Fuel Cap is Loose. A loose fuel cap is probably the easiest fix in relation to a “Check Engine” light. Tightening the cap and restarting your car will most often reset the indicator. If the cap is cracked or the rubber gasket is worn, buying a new fuel cap can help remedy the issue.
  2. Spark Plugs Require Replacement. Your vehicle’s ignition coils and spark plugs should be switched out periodically. When the spark plugs misfire, they impact the vehicle’s combustion chamber. Swapping out the spark plugs is an easy fix and will help your vehicles overall performance.
  3. Faulty Oxygen Sensors. A vehicle has anywhere from 2-4 oxygen sensors, which are responsible for monitoring a vehicle’s air-fuel mixture and adjusting the mix when needed. When an air sensor is not working properly, it can decrease gas mileage, and more importantly, increase the amount of dangerous pollutants emitted.
  4. The Dreaded Catalytic Converter. Ignoring your “Check Engine” light can be very costly if the issue is a faulty catalytic converter, which is responsible for reducing the amount of harmful gases that are expelled from a vehicle’s exhaust system. Replacing this vital component can be expensive, especially if the problem is ignored for a prolonged period of time. Repairing the problem that caused the catalytic converter to go bad is essential in preventing the new converter from the same fate.
  5. Mass Air Flow Sensor Needs Replacement. Your vehicle’s mass air flow sensors monitor its fuel injection system and regulates the amount of air that gets into the engine. If this particular sensor is malfunctioning or broken, it can decrease gas mileage, and more vitally, it can often cause your car to stall.
