This signifies a lean air fuel mixture in bank one and bank two. The fact that both banks is a sign that the engine has a vacuum leak or perhaps an the component that tells the on board computer on your car how much air is entering the engine so it can then calculate how much fuel to put into the engine. This device is an air flow meter or map sensor.
