Our automotive experts have put together the following information about the P228E 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 P228E code.

OBD II Fault Code

  • OBD II P228E

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

    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, 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 below 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 P228E Code

    • Fuel pressure control valve failure
    • High pressure fuel pump failure
    • Leaking fuel lines
    • Leaking fuel injector
    • Powertrain Control Module (PCM) failure
    • Wiring issue
    • Worn or damaged camshaft
