P228F

Fuel Pressure Regulator 1 Exceeded Learning Limits - Too High

DTC P228F, sometimes indicated as P228F00 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing fuel pressure regulator 1 exceeded learning limits - too high.

The fuel pressure regulator is responsible for maintaining a consistent fuel pressure in the fuel system. If the fuel pressure regulator exceeds its learning limits, it may cause the engine to run too rich or too lean.
One possible solution is to replace the fuel pressure regulator. Another solution may be to reprogram the fuel pressure regulator using a scan tool.
