P0087 means fuel pressure in the fuel rail is below the minimum threshold the ECU expects. The engine is not receiving enough fuel, which can cause power loss, misfires, and stalling. This commonly points to a failing fuel pump or clogged fuel filter.

P0087 is a fuel system-related diagnostic trouble code classified as high severity. When your vehicle's ECU detects this condition, it stores P0087 and illuminates the check engine light.
If your vehicle has triggered P0087, you may notice one or more of these symptoms:
Here are the most common causes of P0087, ranked by how likely they are to be the culprit:
No - address this immediately. Low fuel rail pressure can cause stalling, misfires, and potential engine damage from lean running. Do not drive further than necessary. The vehicle may stall in traffic.
Follow these steps to pinpoint the root cause of P0087:
Repair costs for P0087 vary depending on the root cause and your vehicle. Here are typical estimates:
Prices estimated as of March 2026. Costs vary by region, vehicle, and shop.

These codes are often seen alongside P0087 or indicate related issues:
The most common causes are a clogged fuel filter, a failing high-pressure fuel pump (on direct injection engines), or a weak in-tank fuel pump. Leaking injectors, a faulty pressure regulator, or a defective fuel rail pressure sensor can also cause this code.
It is not recommended. Low fuel pressure can cause the engine to stall without warning, which is dangerous in traffic. It also causes lean running conditions that can damage the catalytic converter. Drive only to the nearest workshop.
A fuel filter replacement costs 45-160 EUR. High-pressure fuel pump replacement is the most common fix and typically costs 250-800 EUR including parts and labour. Fuel pressure sensor replacement is cheaper at 60-200 EUR.
Yes, a clogged fuel filter is one of the most common causes. The filter restricts fuel flow, preventing the pump from maintaining adequate rail pressure, especially under high demand. Replace the filter first if it has not been changed recently.
Under heavy acceleration, the engine demands significantly more fuel. A marginally weak pump or partially clogged filter may deliver enough fuel at idle but cannot keep up under load, causing rail pressure to drop below the threshold only during hard driving.
A failing diesel injector knocks on cold start, smokes, and idles rough. Here are the symptoms, the cylinder-balance test, and how to confirm it with OBD2.
Sputtering at speed, hard starts, stalling, and a whine from the tank point to a failing fuel pump. The symptoms, what OBD2 shows, and the cost to put it right.
A 210,000 km imported diesel that looks too clean hides its faults in the OBD2 data. Here are the red flags a scan catches before you wire the money.
Your car dies at every red light, then restarts fine. Here is what causes a car to shut off when you stop, how to find the fault, and what fixes cost.
