What does code P0087 mean on a Ford and is it safe to drive?
P0087: Fuel Rail/System Pressure – Too Low. Here's what it means on your Ford, what usually causes it, what repairs typically cost, and how safe it is to keep driving.
What this code means
The actual fuel rail pressure is lower than the PCM commanded. On direct-injection engines the high-pressure fuel pump is the primary suspect; on port injection engines the lift pump or filter is most common.
Common causes for your Ford
- Failing high-pressure fuel pump (direct injection engines)
- Weak low-pressure lift pump
- Clogged or restricted fuel filter
- Leaking fuel pressure regulator
- Restricted fuel supply line
Symptoms
- Check Engine Light
- Hard starting, especially when hot
- Stalling or stumbling under load or acceleration
- Rough idle
Typical fixes
- Replace high-pressure fuel pump (GDI engines)
- Replace low-pressure (in-tank) fuel pump
- Replace fuel filter
- Inspect and replace fuel pressure regulator
Repair cost range
For a Ford, repairs for P0087 often fall between $200 and $1200, depending on the cause and whether you use OEM or aftermarket parts. Labor rates vary by location.
Known issues on Ford
P0087 on Ford EcoBoost is notorious—the high-pressure fuel pump (HPFP) is a known failure point on the 3.5L and 2.0T. Ford issued several TSBs; HPFP replacement is the most common repair on these engines past 80k miles.
