Several factors can lead to the activation of the check engine light in a 2010 Honda CR-V. One of the primary reasons is a loose fuel cap, which is designed to prevent fumes from escaping the tank. If the cap is not secured properly or is damaged, fumes can leak out and cause the light to come on. Typically, tightening or replacing the cap can resolve this problem. Another common issue is a malfunctioning oxygen sensor, which can result in increased fuel consumption and potential damage to the catalytic converter and spark plugs if not addressed promptly. Faulty spark plugs or ignition coils can also trigger the check engine light. Less frequently, problems with the catalytic converter, mass airflow sensor, vacuum system, hoses, aftermarket alarm, or fuel injector may be the cause of the illuminated light.
