What causes a P0087 code?

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. Low fuel pressure is actually what causes the PCM to activate the Check Engine light.

What happens when fuel pressure is too low?

Some of these symptoms include your engine running rough, poor fuel economy and black smoke from the exhaust. 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.
