What Does P0087 Trouble Code Mean?
The P0087 trouble code means that your car’s Engine Control Module (ECM) has detected that the fuel rail pressure is lower than the specified range.
This code is common in vehicles with direct fuel injection systems.
The fuel rail is a crucial component that distributes fuel to the injectors. When the fuel pressure is too low, it can lead to poor engine performance.
The ECM constantly monitors the fuel pressure to ensure it stays within the optimal range. If the pressure drops below the required level, the ECM triggers the P0087 code.
Low fuel pressure can result from various issues. It could be due to a failing fuel pump, a clogged fuel filter, or a leak in the fuel line.
Additionally, problems with the fuel pressure regulator or the fuel injectors themselves can cause this code to appear.
When this code pops up, you might notice symptoms like engine misfires, reduced power, stalling, or difficulty starting the engine.
The car may also enter “limp mode,” a safety feature that limits engine performance to prevent damage.
Addressing the P0087 code promptly is essential. Ignoring it can lead to more significant engine problems and costly repairs down the line.
Identifying and fixing the underlying issue will restore proper fuel pressure and improve your vehicle’s performance.
In summary, the P0087 trouble code indicates low fuel rail pressure, which can significantly impact your car’s performance.
It requires immediate attention to identify the cause and make necessary repairs to keep your vehicle running smoothly.

How To Fix A P0087 Trouble Code
Fixing the P0087 trouble code involves diagnosing the underlying issue and addressing it. Here’s how you can tackle this problem:
1. Check for Fuel Leaks
Inspect the fuel lines and connections for any signs of leaks. Repair or replace any damaged parts.
2. Inspect the Fuel Pump
Test the fuel pump to ensure it’s working correctly. A failing pump might not provide enough pressure. If it’s faulty, replace it.
3. Examine the Fuel Filter
A clogged fuel filter can restrict fuel flow. Replace the fuel filter if it’s dirty or blocked.
4. Test the Fuel Pressure Regulator
Use a fuel pressure gauge to check if the regulator maintains the correct pressure. Replace it if it’s malfunctioning.
5. Inspect Fuel Injectors
Ensure the injectors are clean and functioning properly. Use a fuel injector cleaner or replace them if necessary.
6. Check Electrical Connections
Verify that all electrical connections to the fuel system components are secure and free of corrosion. Repair any damaged wiring.
7. Scan for Additional Codes
Use an OBD-II scanner to check for other related trouble codes. Address any additional issues that might be contributing to the low fuel pressure.
8. Test Fuel Quality
Ensure the fuel in the tank is clean and not contaminated. Drain and replace the fuel if necessary.
By following these steps, you can identify the cause of the P0087 code and make the necessary repairs. This will restore the proper fuel pressure and improve your vehicle’s performance.
