I have 2009 Honda Civic. A 2413 code came up in the ERG system performance. when I drive on the highway doing 100 mph, the Rpm go up to 4500. Is this because of the valve?

Answer

There could be a problem with a sensor. Check the EGR and the MAP sensors in particular. Make sure all vacuum lines are in good condition.
