What does it mean when it says fuel rail system pressure too low?
P0087 is a general OBD2 diagnostic trouble code that indicates a fault within the fuel delivery system. Low fuel pressure causes the Check Engine Light to trigger by the ECM and a failsafe mode is enacted to prevent damage until repaired.
How do you fix fuel rail system pressure too low?
Check for any leaks of fuel. Obvious leaks where you can see fuel dripping, or smell raw fuel, won’t allow the proper buildup of fuel pressure, which will lead to low pressure condition. Repair as needed. Inspect the fuel lines for kinks that may obstruct the flow of fuel and prevent the required pressurization.
What is a problem that could occur if fuel pressure is too low?
On the opposite side, if fuel pressure is too low, your vehicle could experience a lack of horsepower, slow staring, an inability to start the engine or stalling. When an engine “runs rich” it means that the air to fuel ratio is not at an optimal level and, instead, there is too much fuel and not enough air.
Can a fuel filter cause low fuel rail pressure?
Your pickup employs a no-return fuel system that is unlike the return-based system used on most vehicles prior to 2000. Typical causes for low fuel pressure include a dirty fuel filter, weak pump, incorrect tank venting, restricted fuel lines, a clogged pump inlet strainer and faulty electrical control.
Will low fuel pressure throw a code?
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.
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’s the code for a bad fuel pump?
Bad Fuel Pump, Fuel Pressure Sensor Can Trigger ‘Check Engine’ Light, P0087 Code. Your car’s “Check Engine” or “Service Engine Soon” light can flash on for more than 1,400 different reasons.
What is the code for the fuel rail?
Note: Code P0087 is a generic code specified by the Society of Automotive Engineers (SAE). Depending on the car manufacturer, the code’s definition may change. The PCM keeps track of the pressure levels within the fuel rail.
What does the sensor on the fuel rail mean?
There is a sensor on the fuel rail that monitors fuel pressure and determines if the vehicle needs more or less fuel. When your vehicle’s Engine Control M (ECM) records a code of P0087, it means the fuel pressure in the system is below specification.
What does the p0087 code on the fuel rail mean?
A sensor on the fuel rail measures fuel pressure. It will warn the PCM if the pressure falls below the level expected of the fuel pump driver module or fuel pump assembly’s current activity. In response, the PCM may log the P0087 code.
