P0087

Fuel Rail Pressure Too Low

The engine is not getting enough fuel pressure. This can cause hard starting, poor power, stalling, and misfires. The problem may be in the fuel pump, fuel filter, pressure sensor, wiring, or a fuel leak.

Severity4/5 High
Can I drive?⚠ With caution

You may be able to drive short distances, but the engine can lose power or stall. Avoid heavy acceleration and get it checked soon because low fuel pressure can leave you stranded or damage the engine if misfires occur.

What It Means

P0087 means the engine control module detected fuel rail or fuel system pressure below the target level on bank 1. The pressure drop can be actual, such as from a weak fuel pump or restricted fuel delivery, or it can be a false reading caused by a faulty pressure sensor or wiring issue.

FAQ

Can bad gas cause P0087?

Yes. Contaminated fuel or very low fuel level can cause low fuel pressure and trigger this code.

Is P0087 usually a bad fuel pump?

Often yes, but a clogged filter, bad pressure sensor, wiring problem, or fuel leak can cause the same code.

Will P0087 cause misfires?

Yes. Low fuel pressure can make the engine run lean and cause misfires, hesitation, and stalling.

Can I clear P0087 and keep driving?

You can clear it, but if the underlying problem remains, the code will return and the engine may stall or lose power.

Do I need to replace the fuel pump right away?

Not always. Verify pressure, wiring, filter condition, and sensor readings before replacing major parts.
