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
- 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
Repairs for P0087 often fall between $200 and $1200, depending on the cause and your vehicle.
