Hi there, this code is for pressure being higher than the target value.
Now this could be caused by a couple of things including the fuel pressure sensor itself.
The place to start would be by having the actual fuel pressure checked to see if it's within specifications or not, if it is and still throwing the code then the sensor itself is bad. If the pressure is off then it's likely the result of a faulty suction control valve on the pressure pump.
Let me know if you need anything else.
