P228D OBD-II: Fuel Pressure Regulator 1 Exceeded Control Limits - Pressure Too
P228D Severity
Should you fix P228D yourself?
Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.
Proper diagnosis will save you time and money on unnecessary repairs.
Urgent codes indicate immediate action is necessary. These are urgent and significant malfunctions that can cause severe damage to the vehicle or harm the driver and passengers.
What causes OBD-II fault code P228D?
Many newer vehicles use a direct injection fuel system, which injects the fuel directly into the cylinder instead of into the intake manifold port going to each cylinder. As a result, higher fuel pressure is required. Direct Injection engines have a high pressure fuel pump, usually mounted to the engine. Some high pressure fuel pumps may be mechanically driven by the engine. The Fuel Pressure Regulator (also referred to as Fuel Pressure Control Valve) regulates the fuel pressure coming out of the high pressure pump on direct injection equipped vehicle's. When the engine control module (PCM) detects the actual fuel pressure is above the commanded fuel pressure, it will set this code.
