What might cause my 2015 Honda CRV check engine light to come on?

If the check engine light in Your Honda CR-V starts flashing, that means that the problem needs abrupt attention and Your Honda should be brought in quickly. A flashing light expresses that the problem is genuine and if not taken care of quickly may result in central break to the vehicle. Extra present reasons for a Check Engine Light are d***y mass airflow sensor, faulty head gasket, faulty emissions control part, a malfunction with the fuel injection system, damaged oxygen sensor, or defective spark plugs to name a few.A mass (air) flow sensor (MAF) is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine.
