yes the pressure sensor in mounted in a rubber grommet on the top of the fuel tank. it could be the sensor but the only way to know for sure is have the dealer do a evaporative emissions fuel tank pressure test, they have the special tools to do this, outside shops do not. Have u tried a new gas cap, they can leak and cause the problem, in fact that is very common.

I also have a 04 with a 1.8L. same problem. I took the fuel regulator off. It is a black box behind the rear tire under car. It only has 2 bolts to take off. After that there is a couple of vent hoses from the tank going to this box. Unplug them and 1 electrical connection. The electrical connection and one vent is connected to a T connection on the box that you can unplug by twisting on the T. Take that T off and look inside where you unplugged the hose on this T. There is a spring and a little plunger inside this tube. The plunger gets stuck. I took a little screw driver and some PB blaster and worked that plunger back and forth a couple dozen times and it unfroze. Put it back together gassed up just fine. I did not look but I was told regulator can be replaced for 200$. But a can of blaster is cheaper.
