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 causes fuel rail pressure Code?
Diagnostic Trouble Code (DTC) P0087 stands for “Fuel Rail/System Pressure Too Low.” It may get logged by the PCM when the pressure inside the fuel rail or the fuel system dives below the minimum levels needed to supply the engine with enough fuel to run properly.
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.
Can you clean fuel rail pressure sensor?
Can you clean fuel rail pressure sensor? You can clean the sensor, but it is doubtful that it will make a difference. In some very rare cases, dirt can block the passage to the sensor head, which will make the sensor work again after a clean. However, in most cases, you need to replace the fuel pressure sensor.
