Inspect the fuel lines for kinks that may obstruct the flow of fuel and prevent the required pressurization.Obvious leaks where you can see fuel dripping, or smell raw fuel, wonвЂ™t allow the proper buildup of fuel pressure, which will lead to low pressure condition. In some cases, simply adding a fresh tank of fuel will fix the problem. It is important to have the right amount of fuel to pressurize the lines. Start your diagnosis by making sure you didnвЂ™t run out of fuel.If this happens, you will need to diagnose and repair it first before you can turn your attention to the fuel pressure itself. Many times, this error code is accompanied with other error code, such as O2 (oxygen) sensor lean or rich code. Failed high-pressure fuel pump camp which leads to low fuel pressure (for Volkswagen 2005-2007.ДЇuel pressure monitor donвЂ™t usually run unless the fuel pressure sensor monitor runs first and passed.Collapsed or kinked fuel line problems restricting fuel flow to high pressure (for GM vehicles 2001 to 2004.The most common cause of this error code is clogged filter or fuel screen.

When this happens, a failsafe mode is activated to prevent damages until the problem is fixed/repaired.ДЄside from the activation of the Check Engine light, drivers will also experience drivability issues, such as:Дepending on the severity of the problem or the make and model of the vehicle, the engine may experience hard starting or may simply just stop running. Low fuel pressure is actually what causes the PCM to activate the Check Engine light. A problem usually caused by the fuel pump, fuel supply pipe blockage, fuel pressure regulator or mechanical fault.

Error Code P0087 is triggered when the PCM (Powertrain Control Module) has detected low fuel pressure (or below the specification commanded to the fuel pump driver module or fuel pump assembly) in its fuel pressure sensor. The fuel rail comes with a sensor that monitors its fuel pressure and change the pump speed accordingly.

Also, its pump speed can vary to deliver rail at variable rate, rather than constantly running the fuel pump and regulating the pressure through pressure regulator, returning fuel back to the tank. DefinitionДЇor some vehicles that uses return-less fuel supply, this means their fuel pump is pulse width modulated.

This error code is very similar to Error Code P0088. This indicates a fuel system problem, which is usually a fault within the fuel delivery system. Error Code P0087 is defined as Fuel Rail/System Pressure Too Low.
