• When ambient temperatures are below 0°C (32°F), the fuel tank pickup screen may be iced over from water in the fuel tank.
• When power enhancing devices have been attached to the fuel rail pressure sensor circuits, this DTC may set and adversely effect the fuel system components. (means hack/mods done)
• If the fuel pressure valve is not torqued correctly, the valve will leak fuel into the fuel return system causing this DTC to set. The fuel pressure relief valve uses a bite type seal, and proper torque is essential for valve to rail sealing. Refer to Fastener Tightening Specifications.
• A sticking FRP regulator may cause this DTC to set.
• High fuel injector return flow may cause this DTC to set.
• The addition of fuel system enhancements, such as auxiliary fuel tanks or add on fuel filters may relate to driveability complaints.

P0087 is Fuel Rail/System Pressure - Too Low, indicating a fuel system problem.

What causes the P0087 code?

• The most common cause is a clogged fuel screen or filter
• A failing fuel pump
• A restricted fuel line
• Improperly reading fuel pressure sensor will set P0087 as well

What are the symptoms of the P087 code?

• Check Engine Light illuminated on the dashboard
• Vehicle may run poorly
• Loss of engine power, noticed during acceleration
• Engine misfire
• Vehicle may stop running

How does a mechanic diagnose the P0087 code?

• A mechanic will begin by using a scan tool to read any codes present.
• Once these codes are identified and the freeze frame information looked at for each code they will be cleared.
• Next a road test will be performed under similar conditions as the freeze frame data.
• If the Check Engine Light comes on a visual inspection of the fuel tank, fuel lines, and fuel filter will be performed.
• Manual fuel pressure readings will then be taken at the fuel rail and compared to specifications. A scan tool will then be used to compare manual readings to what the ECM sees.
• Lastly, the fuel pump will be tested.

Common mistakes when diagnosing the P0087 code

• Mistakes are made when steps are skipped or not completed.
• Though the most common cause is a clogged fuel filter this will not fix all vehicles and circumstances.
• It is important to follow the steps so unnecessary repairs are not performed wasting time and money.

How serious is the P0087 code?

P0087 can lead to serious drivability issues. If the vehicle starts running poorly and having misfires it must be diagnosed ASAP to ensure safe driving. If the fuel pump is failing or the fuel filter becomes completely clogged, this may cause the engine to die while driving resulting in serious issues for the driver. A qualified mechanic should be contacted and repairs should be done to get the vehicle safely back onto the road.

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

Additional comments for consideration regarding the P0087 code

A manual fuel pressure tester is needed to diagnose P0087. This allows us to check fuel pressure at the fuel rail and then use the scan tool to check what the fuel pressure sensor is reading. Both of these readings are needed to test the fuel pressure sensor.
An advanced scanner is also needed to monitor fuel pressure sensor data.
Some vehicles may not be equipped with an external fuel filter. These vehicles will only be equipped with the fuel screen that is attached to the fuel pump. These are generally replaced as one unit since the gas tank must be removed from the vehicle in most cases.
Care should be taken when test driving a vehicle with a failing fuel pump. If the fuel pump is failing it may do so when driving causing the vehicle to die while driving or not be able to be restarted.

DTC P0087: Fuel Rail Pressure (FRP) Too Low

Circuit/System Description
The fuel injection pump supplies high pressure fuel to the fuel injection rails, and then to the fuel injectors through high pressure pipes. The fuel rail pressure (FRP) sensor is a three wire sensor mounted in the right fuel injection rail. The FRP sensor uses a 5-volt reference circuit , a signal circuit, and a low reference circuit to monitor fuel rail pressure. This information is sent to the engine control module (ECM) to assist in the fueling of the engine.

Conditions for Setting the DTC
P0087
• The actual FRP is more than 15 MPa (2,176 psi) below the desired FRP.
OR
• The actual FRP is less than 22.5 MPa (3,263 psi).

Action Taken When the DTC Sets
• DTCs P0087 and P0088 are Type A DTCs.
• The ECM commands the engine to operate in the Reduced Engine Power mode.
• The message center displays Reduced Engine Power.

Important: Because of the cleansing properties of the biodiesel, switching from the straight diesel to a biodiesel blend can prematurely restrict the fuel filter with normal deposits in the fuel system. A fuel filter replacement might be required sooner than the recommended interval.
P0087
If DTC P0090, P0168 or P0191 is also set, refer to Diagnostic Trouble Code (DTC) List - Vehicle.
Ignition ON for 90 seconds, verify the scan tool FRP Regulator Command parameter is less than 20 percent.
? If greater than the specified range, replace the ECM.
Attempt to start the engine.
? If the engine does not start, refer to Engine Cranks But Does Not Run.
Install the CH-48027 to the fuel rail service port and slowly increase the engine speed until reaching wide open throttle (WOT). The value should be between 1-4 inches Hg vacuum.
? If more than the specified value, inspect for restricted fuel filter or damaged supply lines.
? If no restriction was found, test for high fuel return flow. Refer to Fuel System Diagnosis - High Pressure Side.
With the engine idling or at an idle, command the fuel pressure control to 180 MPa (26,106 psi) with a scan tool. Observe the Actual Fuel Rail Pressure parameter. The actual fuel pressure should be the same as the commanded pressure.
? If the Actual Fuel Rail Pressure is less than 165 MPa (23,931 psi), refer to Fuel System Diagnosis - High Pressure Side.
Important: If the fuel temperature is near 121°C (250°F) during the duplication of the complaint, or in the Failure Records for this DTC, inspect for a restriction in the fuel cooler air flow or the fuel heater always ON. Refer to Fuel Heater Always On.
Operate the vehicle within the conditions for which the customer complaint occurs while observing the CH-48027 . You may also operate the vehicle within the conditions that you observed in the Freeze Frame/Failure Records.
? If the vacuum was more than 12 inches Hg of vacuum at any time in the operating range, inspect for kinked or restricted fuel supply lines.
Operate the vehicle within the conditions for which the customer complaint occurred. Observe the Actual fuel Rail Pressure and Desired Fuel rail Pressure parameters with a scan tool. Fuel pressures should be the same for both parameters.
? If the Actual Fuel Rail Pressure is less than the Desired Fuel Rail Pressure, refer to Fuel System Diagnosis - High Pressure Side.
? If fuel system tests normal, refer to Diagnostic Aids.

for code p0087 replace the GDI GASOLINE DIRECT INJECTION (HIGH PRESSURE PUMP( the pump is in the top o the engine down the plastic cover- they have two gasoline lines an one electrical connector,and 2 bolts . remove return line, remove the electrical connector, loose the 19mm bolt for the main gasoline line dont move this line, remove bolts of the pump and move it away, when you work with gasoline lines is dangerous (it is at you own risk( THE CODE P0191 IS RELATED FOR FUEL RAIL PRESSURE SENSOR usually appears with p0087. symtoms of bad fuel pump: long cranking time,,erratic idle. not enough power. no start condition= pump is easy to change=

P0087 is a low fuel rail pressure code. One of 2 likely causes. the quick diagnosis is to turn the key into the "on" position and listen for the fuel pump hum. If there is a hum, but the van doesn't start, I would then check the fuel filter. in between 80k and 100k miles, some of the sprinters run into a fuel filter issue where the fuel is too restricted to flow to the injectors properly. If you don't get enough fuel through the injectors, the engine will rotate, but not get enough vapor concentration to start.

What kind of vehicle is it, Give better details

P0087- low pressure fuel system. Fuel pressur valve stock open, Fuel volume control valve stuck close, Leaking fuel injector,P0088- fuel pressure contorl valve stuck close, Fuel rail pressure sensor P2291-all @ at the above, means to say poor fuel quality

I can't remember that year exactly so help me out it's been a while
is that a IDI diesel that has a injector pump sitting in top center front of engine (has all the fuel lines running off it) or is it a Direct inject engine that has the injectors all comming off a central fuel rail

IDI diesel = sensor is on pump front lower under cold throttle kicker coil

direct inject= sensor is on driver side at end of fuel rail toward fire wall
