What might cause my 2017 Chevy Traverse check engine light to come on?

Common reasons for a check engine light on the 2017 Chevy Traverse are a faulty head gasket, damaged oxygen sensors, faulty emissions control parts, a d***y mass airflow sensor, a malfunction with the fuel injection system, or some defective spark plugs to name a few.But why are spark plugs so important. Well Your spark plugs are what supply the spark that ignites the air/fuel mixture, creating the explosion which makes Your engine produce power. These small but simple plugs create an arc of electricity across two leads which are not touching, but close enough together that electricity can jump the gap between them. If Your spark plugs ever need to be replaced the typical amount You will pay for spark plugs is between $20 to $100.
