    That code can be cleared with an appropriate scan tool but if the fault isn't diagnosed and repaired, it will come right back on.
    That code refers to the fuel tank pressure sensor, located on the top of the fuel tank. If the sensor doesn't provide the Engine Control Module (ECM) with the proper information at the proper time, the ECM will turn on the light.
    Your best bet is to have this properly diagnosed and repaired to keep that light from coming on.
