P0087 on Genesis
Fuel Rail/System Pressure - Too Low
P0087 on Genesis vehicles indicates fuel rail/system pressure - too low. Au7o has documented this code across 1 Genesis model — most commonly on GV80. This code means the fuel rail or fuel system pressure has dropped below the level the engine's computer expects. The computer monitors a fuel pressure sensor and has seen pressure fall too low, meaning the engine isn't getting enough fuel — especially noticeable under acceleration or load. This is most common on direct-injection and diesel systems that run very high pressures. Symptoms include hard starting, stalling, hesitation, lack of power, and possible limp mode.
Common Causes of P0087
- •Clogged or dirty fuel filter
- •Weak or failing fuel pump (lift pump or high-pressure pump)
- •Faulty fuel pressure regulator or control valve
- •Restricted or leaking fuel lines
- •Faulty fuel pressure sensor
- •Air in the fuel system or running low on fuel
- •Worn high-pressure pump (direct injection/diesel)
P0087 on Genesis by Model
Genesis GV80(1 issue)
- Low-Pressure Fuel Pump Impeller Deformation Causes Stalling (Recall 022G / NHTSA 24V282)2022-2023
The low-pressure fuel pump impeller can deform under high ambient temperatures, causing it to interfere with the pump housing and shut down. Symptoms include rough idle, hesitation/stumbling, MIL illumination, and engine stall while driving. Genesis recalled ~31,440 GV70/GV80/G80/G90 vehicles; GV80 production dates Nov 4 2021 through Sep 13 2022.
