P0087 on Kia
Fuel Rail/System Pressure - Too Low
P0087 on Kia vehicles indicates fuel rail/system pressure - too low. Au7o has documented this code across 1 Kia model — most commonly on Sorento. 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 Kia by Model
Kia Sorento(1 issue)
- High-Pressure Fuel Pipe / Fuel Rail Leak and Fire Risk (2.5L Turbo)2021
Certain 2021 Sorento (and 2021-2022 K5) models with the 2.5L turbocharged engine can leak fuel at the pipe connection between the high-pressure fuel pump and the fuel rail. The pipe was either torqued below specification at assembly or, in a limited number of cases, manufactured out of spec for concentricity, allowing high-pressure fuel to weep at the joint. A fuel leak in the hot engine bay raises the risk of an underhood fire. NHTSA recall 21V519 (Kia SC214) covers the affected vehicles.
