Common error code.
If you follow your air intake pipe from the left hand side of the engine bay where it creeps up to the manifold, this is where the throttle body is.
Just take off the air intake pipe from the throttle body and open the butterfly valve and clean the inside of your throttle body. The error code you get is typically from a build up of carbon that is preventing the valve from either openeing or closing all the way.
You will want to use carb cleaner. Open the butterfly valve and spray away and use a Q-tip or whatever will reach inside. When I cleaned my throttle body, I did not even remove it from the manifold, I just held the valve open and sprayed inside and cleaned. When I fired up the car, the car ran like crap for about 10 seconds while the engine burned up the cleaner that made it inside but after that it ran super smooth.
