How to solve the problem of fault code P0090

[carstr50]

my 2008 ford focus car "Fuel Pressure Regulator 1 Control Circuit Error Code" gives warning. whatever I did didn't get better. Can you help urgently? i don't understand anything from what this site says p0090 code

Is the car suffering any issues and if so, what ?

a code on its own with no issues doesn't mean much.
