P228D - OBD II Trouble Code

Our automotive experts have put together the following information about the P228D diagnostic trouble code. We've provided the common symptoms that occur when this code is set along with the frequent repairs that address the issues related to the P228D code.

OBD II Fault Code

• OBD II P228D

OBD-II Code Decreased engine performance is defined as a Fuel Pressure Regulator 1 Exceeded Control Limits - Pressure Too

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.

Decreased engine performance Symptoms

• Decreased engine performance
• Engine may stall
• Increased fuel consumption

Common Problems That Trigger the P228D Code

• High pressure fuel pump failure
• Powertrain Control Module (PCM) failure
• Restriction in the fuel system
• Wiring issue
• Worn or damaged camshaft

Common Repairs Needed for the P228D Code

• Fuel Pump Replacement
