Check Engine Light

I agree, but you won't pass an emission inspection with the light on or maybe due to the fault. Don't worry about that particular diagnostic code as far a reliability, but I recommend you get it fixed soon. if the light is flashing, it means that there's a condition detected that could cause imminent damage to the catalytic converter.
