What is P0087 : Engine Error code Causes Explained
This Guide covers the P0087 engine trouble code, which indicates low fuel rail pressure. Clogged gasoline filters, fuel pumps, and fuel pressure regulators can cause poor engine performance and damage if not rectified.
How to Identify a DTCs Number
The P0087 error code indicates a low fuel rail pressure, which can occur when the fuel pressure in your engine’s fuel system falls below the necessary threshold. To identify a DTC (Diagnostic Trouble Code) number like P0087, you need to understand the format and function of the code.
Understand that the trouble codes (DTCs) are 5 characters: 1 letter, 4 numbers. P-Powertrain indicates the fault code’s location. Generic or manufacturer-specific codes are indicated by the first digit. The second digit denotes the subsystem (7=transmission). The last two numbers describe the issue.
This diagnostic trouble code (DTC) typically appears when the Engine Control Module (ECM) detects that the pressure sensor is reading below the set value for the fuel system.
Causes of P0087 Code:
- Clogged fuel filter:
A dirty or clogged fuel filter restricts fuel flow, leading to low fuel rail pressure. - Faulty fuel pump:
A failing fuel pump, whether due to wear and tear or internal issues, can’t deliver enough pressure to the fuel rail. - Restricted fuel line:
Damaged or kinked fuel lines can impede fuel flow. - Faulty fuel pressure sensor:
If the sensor is sending incorrect pressure readings to the ECU, it can trigger a P0087 code even if the actual pressure is adequate. - Camshaft timing issues:
In rare cases, worn camshaft lobes that drive the fuel pump can contribute to low pressure.
Risk Level of P0087 Error Code:
The “High Risk Level” associated with this code is due to the potential impact it has on the engine’s performance and overall health.
This code generally indicates a more serious issue that might harm the engine or impair performance.
Common Car Brands Affected by P0087 Code:
The P0087 engine error code is commonly found in following list.
- Volkswagen
- Vauxhall
- Land Rover
- Ford

FAQ’s
What is the P0087 engine error code?
The P0087 code indicates that the fuel pressure is too low in the fuel rail, meaning there’s insufficient fuel being delivered to the engine.
What causes the P0087 engine error code?
Common causes include a failing fuel pump, clogged fuel filter, defective fuel pressure regulator, or a malfunction in the fuel pressure sensor.
What is the risk level associated with the P0087 code?
The risk level is moderate to high. Ignoring this error can lead to poor engine performance, reduced fuel efficiency, and potential engine damage.
Which cars are affected by the P0087 code?
The P0087 code can affect many vehicles with fuel-injection systems, including models from brands like Ford, BMW, Mercedes, and Volkswagen.
