What is P0087 Fault-Error Code?
P0087 Fault-Error Code is an OBD-II fault code that indicates that there is a problem with the fuel system in vehicles. This code stands for “Fuel Rail/System Pressure – Too Low”. Fuel pressure refers to the pressure of the fuel pressed towards the injectors.
This error is usually related to the following subsystems:
Fuel pump: The fuel pump carries fuel from the fuel tank to the injectors. If the fuel pump is not working properly or cannot maintain pressure, error P0087 may occur.
Fuel filter: A dirty or clogged fuel filter can block fuel flow, causing system pressure to drop.
Fuel pressure sensor: The fuel pressure sensor measures fuel pressure and transmits this information to the engine. If the sensor is faulty or gives incorrect information, error P0087 may occur.
Fuel pressure regulator: The fuel pressure regulator regulates fuel pressure. If the regulator is broken, it can cause a drop in pressure.
What are the symptoms of P0087 Fault/Error Code?
Symptoms of the P0087 malfunction/error code may indicate the following in the vehicle:
Loss of Power: A drop in fuel pressure can prevent the engine from producing enough power. In this case, the vehicle may lose power. It may be especially noticeable during acceleration.
Engine Shudder: Low fuel pressure can cause the engine to run erratically. This can lead to erratic operating problems that may be felt like engine shaking or shuddering.
Engine Operating Problems: Low fuel pressure can affect proper engine operation. Problems such as engine idle fluctuation, difficult starting or occasional stalling may occur.
Low Fuel Efficiency: Low pressure in the fuel system can prevent fuel from being sprayed into the injectors correctly. In this case, the vehicle may consume more fuel.
Check Engine Light: P0087 Trouble/Error Code indicates a problem detected by the vehicle's engine control unit. In this case, the malfunction lamp may come on or a warning message may appear on the vehicle.
What could be the causes of P0087 Fault/Error Code?
The reasons for the P0087 Fault/Error Code may be various. Among them:
Fuel Pump Problems: A malfunction or poor performance of the fuel pump can cause the fuel pressure to drop. This may be due to a mechanical fault in the pump, a problem with the electrical connections or a clogged fuel filter.
Fuel Filter Clogging: A dirty or clogged fuel filter can prevent the proper flow of fuel, causing fuel pressure to drop.
Fuel Pressure Sensor Malfunction: The fuel pressure sensor measures the fuel pressure and transmits this information to the engine control unit. If the sensor is faulty or providing incorrect information, code P0087 may occur.
Fuel Pressure Regulator Problems: The fuel pressure regulator regulates fuel pressure. A faulty regulator can cause fuel pressure to drop or rise.
Fuel Line Leaks: Leaks in the fuel line can lead to loss of pressure and ultimately cause the fuel pressure to drop.
Fuel Injectors Problems: Defective or clogged fuel injectors can prevent fuel from being properly sprayed into the cylinders, resulting in low fuel pressure.
Fuel Tank Problems: A problem in the fuel tank can prevent fuel from being pumped properly, resulting in low fuel pressure.
What Steps Should Be Followed to Resolve the P0087 Fault/Error Code?
The following steps can be followed to solve the P0087 fault/error code:
Checking the Fault Code: First, the accuracy of the P0087 code must be confirmed by scanning the fault code in the vehicle. For this, it is necessary to check the OBD-II scanner or the fault lamp on the vehicle.
Checking Fuel Pressure: Fuel pressure should be checked using a pressure gauge. The pressure should be at a certain level depending on the operating condition of the vehicle. If it is lower than a certain pressure, it can help find the source of the problem.
Fuel Pump Check: It should be checked whether the fuel pump is working correctly. For this purpose, electrical power can be supplied to the pump to check whether it is working or whether the fuel pressure is sufficient.
Fuel Filter Replacement: A dirty or clogged fuel filter can cause low fuel pressure. In this case, the filter must be replaced.
Checking the Fuel Pressure Sensor: The fuel pressure sensor must provide accurate pressure information. If the sensor is faulty or giving incorrect information, it may need to be replaced.
Control of Fuel Pressure Regulator: The fuel pressure regulator regulates fuel pressure. A faulty regulator can cause pressure drop. In this case, the regulator may need to be checked and replaced if necessary.
Inspect the Fuel System: Fuel line leaks, problems with fuel injectors or other parts can also cause low fuel pressure. Therefore, the fuel system should be inspected in general and problematic parts identified.
What are the Long-Term Effects of the P0087 Fault/Error Code?
The long-term effects of a P0087 fault/error code may vary depending on the cause of the fault, how long the vehicle has been used this way, and how the fault is handled. However, in general, the following negative effects may occur:
Decreased Engine Performance: Low fuel pressure can affect engine performance. Symptoms such as loss of power, acceleration problems, irregular operation can negatively affect the performance of the vehicle in the long run.
Increased Fuel Consumption: When there is a problem with the fuel system, fuel efficiency may decrease. This can mean higher fuel consumption and therefore increased operating costs in the long run.
Risk of Damage to Other Parts: Low fuel pressure can damage other parts of the engine. Particularly parts such as fuel injectors and fuel pump may fail or wear out more in the long run.
Increased Exhaust Emissions: Low fuel pressure can cause erratic combustion. This may lead to increased exhaust emissions and further damage the vehicle to the environment.
Engine Damage: Long-term low fuel pressure can cause the engine to operate at constantly low performance. In this case, overheating of the engine may lead to more serious engine damage such as damage to the valves.
Long-Term Costs: Using the vehicle for a long time with low fuel pressure may result in costly repairs and maintenance requirements in the long term due to increased fuel consumption, loss of performance and possible part failures.
It is important that fault codes such as P0087 Fault/Error Code are not ignored and resolved as soon as possible. They may present potential risks that may negatively affect the performance, reliability and costs of the vehicle in the long term.
