How do I fix code P0087?
How do I 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.
Can clogged fuel filter cause low fuel pressure?
A clogged fuel filter causes low fuel pressure that results in a lean fuel condition and engine misfire. This can result in poor fuel mileage, rough idling and possibly cause the check engine light to come on.
Can low fuel cause P0087?
Trouble Code: P0087 Fuel Rail/System Pressure – Too Low 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.
How do you test a Ford fuel rail pressure sensor?
With the fuel pressure sensor disconnected, plug the multimeter into the diagnostic port of your car’s computer. Plug the lead into the fuel pressure sensor, which should show “DFPT” on the multimeter display. You should also see “123db”, which is a reference to the distance between the sensor and the connector.
Can a weak battery cause low fuel pressure?
The fuel pump can run slower if the battery is low. This causes low fuel pressure and a lean fuel condition. A low battery can prevent one or more injectors from opening, which can cause lean misfire and/or hard starting.
Can you clean a 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.
