Dtc Codes

My check engine light came on yesterday. I have an efi live autocal unit and ran the dtc codes on it. It returned the code ECM P0454-"Evaporative Emission Control System Pressure Sensor Intermittent". My truck is an 09 silverado with a 5.3 and has 25,000 miles on it. Any ideas on what to do?
