P0087 on Jaguar
Fuel Rail/System Pressure - Too Low
P0087 on Jaguar vehicles indicates fuel rail/system pressure - too low. Au7o has documented this code across 1 Jaguar model — most commonly on XJ. 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. Typical repair costs on Jaguar range from $400 to $1,500, depending on the specific model and root cause.
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 Jaguar by Model
Jaguar XJ(1 issue)
- X350 Saddle-Tank Twin Fuel Pump / Jet Pump Failure — Stalling, Hesitation and Erratic Fuel Gauge2004-2009
The 2004-2009 X350/X358 uses a saddle-shaped fuel tank straddling the driveshaft, with a lift pump on one side and a venturi jet pump transferring fuel from the other. When the jet pump or the lift pump module degrades, the engine side of the tank runs dry even though the gauge shows fuel: owners report momentary stutters or stalls at highway speed, hard starts in cold weather, and gauges that drop suddenly or read unreliably because the level senders are built into the non-serviceable pump modules. It affects the V8 and V6 petrol cars and the 2.7 diesel. The pump module is a sealed unit so the sender is replaced with the pump.

What does P0087 mean on Jaguar?▼
P0087 stands for "Fuel Rail/System Pressure - Too Low." 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. On Jaguar specifically, this code is documented across 1 model.
