P0087 on Mitsubishi
Fuel Rail/System Pressure - Too Low
P0087 on Mitsubishi vehicles indicates fuel rail/system pressure - too low. Au7o has documented this code across 1 Mitsubishi model — most commonly on Outlander. 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)

- Fuel Pump Failure Causing Engine Stall (Recall 22V027)2022
NHTSA recall 22V027000 and Mitsubishi campaign SR-22-001 cover certain 2022 Outlander vehicles. The commutator and wires inside the fuel pump may have been fused incorrectly, which can cause the pump to fail; fuel-pump failure can stall the engine and increase crash risk. NHTSA lists 16,616 potentially affected vehicles. This is a VIN-controlled safety recall, not a diagnosis that every 2022 Outlander fuel pump is defective.
