P0088 on Land Rover
Fuel Rail/System Pressure - Too High
P0088 on Land Rover vehicles indicates fuel rail/system pressure - too high. Au7o has documented this code across 1 Land Rover model — most commonly on Range Rover Evoque. P0088 means the engine computer detected that fuel rail (or fuel system) pressure is higher than the maximum allowed. On modern direct-injection and high-pressure systems, the computer regulates rail pressure precisely and watches the fuel pressure sensor; if pressure climbs too high, it sets this code to protect injectors and components. Excessive pressure usually points to a stuck or failed pressure regulator/control valve, a restricted return, or a sensor reading fault. Symptoms can include rough running, hard starting, hesitation, or the engine entering a reduced-power mode. Typical repair costs on Land Rover range from $800 to $2,000, depending on the specific model and root cause.
Common Causes of P0088
- •Faulty fuel pressure regulator or pressure control valve
- •Stuck-closed or restricted fuel return line
- •Failed or inaccurate fuel rail pressure sensor
- •High-pressure fuel pump control fault
- •Wiring/connector issues at the regulator or sensor
- •Clogged fuel return or relief mechanism
- •PCM/ECM control or calibration fault
P0088 on Land Rover by Model
Land Rover Range Rover Evoque(1 issue)
- Ingenium Engine High-Pressure Fuel Pump Failure2020-2025
The Ingenium 2.0L turbo engine used in the second-generation Evoque experiences high-pressure fuel pump failures that cause hard starting, rough running, and loss of power. The pump's cam follower wears prematurely, reducing fuel rail pressure below the threshold needed for direct injection. JLR has updated the pump design but early vehicles may still have the original part.

What does P0088 mean on Land Rover?▼
P0088 stands for "Fuel Rail/System Pressure - Too High." P0088 means the engine computer detected that fuel rail (or fuel system) pressure is higher than the maximum allowed. On modern direct-injection and high-pressure systems, the computer regulates rail pressure precisely and watches the fuel pressure sensor; if pressure climbs too high, it sets this code to protect injectors and components. Excessive pressure usually points to a stuck or failed pressure regulator/control valve, a restricted return, or a sensor reading fault. Symptoms can include rough running, hard starting, hesitation, or the engine entering a reduced-power mode. On Land Rover specifically, this code is documented across 1 model.
What causes P0088 on Land Rover vehicles?▼
Common causes on Land Rover: Faulty fuel pressure regulator or pressure control valve, Stuck-closed or restricted fuel return line, Failed or inaccurate fuel rail pressure sensor, High-pressure fuel pump control fault, Wiring/connector issues at the regulator or sensor. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0088 on a Land Rover?▼
