What could be the reason for the check engine light illuminating in my 2015 Honda CRV?

If the check engine light on your Honda CR-V starts flashing, it indicates a serious issue that requires immediate attention and your Honda should be taken to a mechanic promptly. A flashing light signals a significant problem that, if not addressed quickly, could cause major damage to the vehicle. Some common causes for a check engine light include a faulty mass airflow sensor, a damaged head gasket, a malfunctioning emissions control component, issues with the fuel injection system, a malfunctioning oxygen sensor, or faulty spark plugs, among others. The mass airflow sensor, also known as a MAF sensor, is a crucial component in determining the amount of air entering a fuel-injected internal combustion engine. This data is crucial for the engine control unit to accurately balance and deliver the proper amount of fuel to the engine.
