2011 Buick Lacrosse 3.6 code p0087???

code p 0087 refers to fuel system/rail pressure ---too low ===causes --fuel pump---fuel pressure regulator --fuel supply pipe blockage --mechanical fault ---EVAP system not venting the tank

What parts do you recommend for a fault on my Hyundai Tucson which has developed faults?

uh oh, 1186 and 0087 are both related... fuel pump or the filter or both! either case the filter is now located inside the fuel tank

P1186 Hyundai Fuel Pressure Too Low

P0087 Fuel Rail System Pressure Too Low

"Potential causes of a P0087 trouble code may include: Weak fuel pump, clogged filter or screen, restricted fuel supply line Faulty fuel pump driver module Faulty fuel pressure sensor"

How to Change the Fuel Filter on Hyundai Tucson eHow

according to eHow, you can access the filter relatively easily. (although the pic is an illustration of something not really related to this ~ why they showing a fuel petcock that's not even on your car?)

P2112 Throttle Actuator Control System Stuck Closed

"Possible causes:
- Throttle Body Plate Binding
- Faulty Throttle Actuator
- Throttle Actuator harness is open or shorted
- Throttle Actuator circuit poor electrical connection"

older models we had the gas pedal attached to a cable to move the butterfly valve on the throttle body. Now it's this newer drive-by-wire stuff... remove air intake hose and check / clean / move the throttle body valve by hand first to see if it's binding or not

then, go from there on testing the actuator and tps

P0313,p008A,p0087 . I don't understand this codes from my Lr4 2010

code p0313 refers to misfire detected---low fuel level===causes-- fuel system ---mechanical fault ( check fuel pressure, fuel filters and fuel pump)
code p0087 refers to fuel rail /system pressure --too low=== causes --fuel pump,--fuel pressure regulator--fuel supply line blockage--mechanical fault. ( have the fuel system pressure tested.)
The code you have listed as p008A is not in the book and you have not given an make or engine model to refer to in other places. I will refer to the code as p0084 which refers to exhaust valve control solenoid, bank 2--circuit malfunction===causes --wiring--exhaust valve control solenoid---ECM ( this will present as a rough running engine or problem starting/ shutting down

08 Chevy Kodiak c4500 duramax desiel i replaced the MAF sensor because the code reader said P0102 now it says P0087 that is the problem but everytime I'm hauling something the engine always decreases its speed when going uphill then the engine light come on so I reset the system good until the hills and back to square 1 what do you think I should do to fix it and what parts should need

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.

Fuel Pressure Regulator Solenoid Supply Voltage
P0088, P0090
P0087, P0191, P2510
Conditions for Setting the DTC
• The actual FRP is more than 15 MPa (2,176 psi) below the desired FRP.
• 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.
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.
