That code is for a fault with the Fuel Tank Pressure sensor.
The sensor is located on top of the fuel tank.

You will have to drop the fuel tank to access the sensor

did the code come on soon after the last time you filled up on gas or between fill ups? I had the same problem. The check engine light came on the day after I filled up on gas. 250 dollars and two days later, the dealership told me the code came on because the GAS CAP was not on tight!
 Hope this helps you, wish I would have known
