Hello. And thanks for the donation. Much appreciated.
I would be looking at changeing the fuel filter then adding a good fuel system cleaner before replacing the presssure sensor. The sensor is there regulate pump activity and to pick up faults in fuel pressure. Because the code is saying "circuit" does not mean the sensor is bad. I was an RAC and greenflag tech for 10 years with a garage at our base and cannot recall ever replacing the sensor either. Of course this is not a guarentee they dont fail !
This description is not off your vehicle as I don't have a manual for you vehicle which was not released here in the U.S.A.. But they all do the same thing. When was the last filter change? Try changeing the filter and adding the cleaner. Let me know if this does/does not help. In the meantime I will contact a friend back in the u.K. For some information.
Electronic returnless fuel system does not use a fuel
pressure regulator. Electronic returnless fuel system uses a Fuel Rail Pressure (FRP) sensor to sense fuel pressure. FRP sensor is located in fuel injection supply manifold assembly. FRP sensor input signal is used by the Powertrain Control Module (PCM) to vary the duty cycle output to the Fuel Pump Driver Module (FPDM) to compensate for varying loads. FPDM then modulates voltage to fuel pump to achieve proper fuel pressure. Engine fuel temperature sensor input signal is also used by PCM to vary fuel pressure to avoid fuel system vaporization.
