HI,Ok, this code is for fuel rail pressure sensor too high. Possible causes are faulty fuel pressure regulator control valve, faulty fuel rail pressure sensor, faulty fuel injector control module or faulty fuel pump. The fuel pressure needs to be tested, as well the fuel rail pressure sensor, and fuel injector control module in order to determine where the fault lies and then repaired as needed.
