That code indicates an EGR position sensor high. This means that the voltage the signal is sending is too high.
This could mean that there is a problem with the sensor or something else is wrong and it's sending the sensor bad information.
There is a whole procedure on how to test for this code. You would do best to go to an ASE certified shop or dealership to get a diagnosis of the problem.
