I got a p1143 code a month ago, and drove like that until now when I
can not fill my gas tank - it takes me about 20 min to fill tank; I
replaced the pressure control solenoid valve, but check engine light came on again; I do not now if it is the same code or a different one.
I would appreciate any suggestions on how to try fixing this problem!

P1143 Pressure Sensor Circuit Low Input Possible Causes
* Pressure sensor vacuum line damaged, loose or disconnected * Pressure sensor signal circuit is open or shorted to ground * Pressure sensor reference (5v) circuit is open or shorted to ground * Pressure sensor has failed
Check for a 5 volt reference on the reference wire Check the voltage on the signal signal wire. 4.0-4.2V KOEO (key on engine off), 2.0-2.3V with manifold vacuum applied. And be sure it has a good ground key on engine off and running.
only advice i can give it take the instrument cluster out of the dash and remove the light bulbs for both items. although it's not smart advice but it will solve your problem of not wanting to have it fixed correctly.
your strong smell of fuel was in side the car , under the hood . ? now check to see if here is any gas leak under the hood --- gas line , filter. check under the car for any leak , or by the gas tank . it might be just sweating, make a good check , re ply me what you find
there is an anti-syphoning screen inside the filler tube. The screens can get plugged up. To remove filler neck, there are three screws by the gas cap, and another 3 on the tank. Not hard at all. Just make sure your tank is less than 1/4 full
When your check engine light comes on, the car is telling you there's a problem, but it's still okay to drive to your destination. When the check engine starts blinking at you, that means pull over and turn off the car before you incur more damage. Please keep in mind that you shouldn't be driving it indefinitely without having your code checked (you can rent a code reader from most car parts stores) but that you probably won't kill anything if you drive it for a few more days.
There is a vent hose (rubber) attached to the fill tube, it's much smaller than the fill tube, and it lets the air out as u fill tank. If u have this trouble, the vent hose is probably kinked, or bent which would slow the speed of filling the tank. Follow the tube and check, let me know what u find.
