OBD-II Trouble Code Technical Description
Low Pressure Fuel System Pressure – Too High
What does that mean?

This generic powertrain diagnostic trouble code (DTC) typically applies to all OBD-II vehicles. That may include but is not limited to vehicles from Hyundai, Ford, Mazda, Dodge, etc.

Low fuel pressure systems are generally used in diesel systems. The fact that the injection pump does the heavy labour as far as providing diesel engines with the high fuel pressures they need in order to atomize the fuel adequately.

That said, the injection pump still needs to be provided with the fuel in the first place. This is where low fuel pressure pumps/systems come into play. It is extremely important for the ECM (Engine Control Module) to monitor these conditions closely.
