Hi there,

This code refers to the fuel tank pressure sensor. The sensor changes as the pressure in the gas tank changes. This changes based on the ambient temp and the fuel evaporating. This causes the pressure to increase inside the gas tank. Several things can set this code off. If the vent control valve or the purge control valve isn't working properly then the pressure in the tank won't change. This will cause this code. Also, if the pressure sensor itself is bad you would get this code.
