Any one know how to fix this
I just started getting a cel on my e55 and trying to find out where the problem could be.

The OBD-II gave the P0451 & p0455 codes as noted below.

P0451
Evaporative Emission Control System Pressure Sensor Range/Performance

p0455
Evaporative Emission Control System Leak Detected (gross leak)

I just replaced the gas cap and that was not the problem and from time to time smell gasoline fumes in the car for a minute or so. If anyone has any clue with what this might be so i don't need to make a trip to the stealer.
