Answer 1

P0190 Fuel rail pressure sensor circuit malfucntion

You would need to do a fuel pressure test. If this code was a P0193 (Fuel rail pressure sensor circuit high) , The fix would be to replace the fuel rail pressure sensor, With P0193 you cannot do a fuel pressure test until P0193 is resolved. What you have is a P0190 This does not mean that the problem is with the FRP sensor, fuel pressure has to be tested, The specification for the fuel pressure is 27 psi to 37 psi at idle
