When your vehicle’s Engine Control M (ECM) records a code of P0087, it means the fuel pressure in the system is below specification. Symptoms of a P0087 diagnostic trouble code may include a misfire because of a lean fuel condition, and the vehicle might run rough or lack power on acceleration.
How do you fix code P0087?
What repairs can fix the P0087 code?
- Replacing the fuel filter or screen.
- Replacing kinked fuel lines.
- Removing and replacing the fuel pump.
- Replacing a faulty fuel pressure sensor.
What causes a P0087?
The error code P0087 is triggered when the PCM (Powertrain Control Module) detects low fuel pressure in its fuel pressure sensor. This problem is normally caused by the fuel pump, fuel supply pipe blockage, fuel pressure regulator, or a mechanical fault.
What causes low fuel rail pressure?
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 happens if fuel pressure is too low?
Decreased 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.
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.
Can a fuel filter cause low fuel rail pressure?
Clogged Fuel Filter
The fuel filter cleans the fuel entering the engine. The fuel filter should be replaced within special intervals, and if you have not changed it for a long time – it might be a clogged fuel filter causing low fuel pressure.
