OBD II Fault Code

  • OBD II P228C

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, 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
