What does code P0087 mean on a Dodge and is it safe to drive?
P0087: Fuel Rail/System Pressure – Too Low. Here's what it means on your Dodge, 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 Dodge
- 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 Dodge, 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 Dodge
Dodge HEMI P0087 typically means a failing in-tank fuel pump on high-mileage engines. The 5.7L HEMI's fuel pump module is accessible under the rear seat. Before replacement, check the fuel pressure regulator on the fuel rail—a stuck regulator can also cause low rail pressure.
