What causes fuel rail pressure too high?
Causes of High Fuel Pressure As we discussed, high fuel pressure means that the air to fuel ratio is off-kilter. The causes for this imbalance of fuel pressure typically include either a bad fuel regulator or a clogged return line.
What causes fuel rail pressure too low?
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.

What causes code P0088?
Diagnostic trouble code (DTC) P0088 stands for “Fuel Rail/System Pressure – Too High.” It is set when the powertrain control module (PCM) perceives a fuel rail pressure or fuel pressure sensor voltage input that may be higher than the set specifications.
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.
How much does it cost to replace a fuel rail pressure sensor?
In general, the cost of replacing a fuel rail pressure sensor is about $262. Parts cost an average of $135, while labor costs an average of $126.
What is a fuel regulator?
A fuel pressure regulator (FPR) is a device that controls the pressure of fuel supplied to the fuel injectors on an engine.
