What causes code P228D?
The trouble code P228D can be elucidated as Fuel Pressure Regulator 1 Exceeded Control Limits – Pressure Too High. This error code would start appearing when a high voltage signal from the control circuit of the electronic fuel pressure regulator would be detected by the powertrain control module.
What are the symptoms of low fuel pressure?
Low fuel pressure can lead to engine misfires, low acceleration, rough idles, and engine stalls. If your check engine light is on and your car has been stalling out, you may have a fuel pump failure.

What causes low pressure in fuel rail?
Three of the most common causes of heavy equipment low fuel pressure are a faulty regulator, a fuel pump malfunction or problems with the fuel lines.
Where is the fuel rail pressure sensor located?
A fuel rail pressure sensor (commonly known as a fuel pressure sensor) is used in many diesel and some gasoline engines. This sensor is usually located near the middle of the fuel rail and is linked to the engine control unit (ECU), which is the central computer of a vehicle.

What is a fuel pressure sensor?
The fuel tank pressure sensor is part of the fuel pump assembly and is mounted on top of the tank or inside the tank. It’s part of the evaporative emissions system (commonly referred to as “EVAP”) and reads pressure in the fuel system to detect evaporative leaks, such as a loose or faulty gas cap.
