P0191 on Land Rover
Fuel Rail Pressure Sensor Circuit Range/Performance
P0191 on Land Rover vehicles indicates fuel rail pressure sensor circuit range/performance. Au7o has documented this code across 1 Land Rover model — most commonly on Range Rover Evoque. This code sets when the fuel rail pressure sensor's signal is out of its expected range or doesn't match what the computer expects for current conditions. On direct-injection and many modern engines, this sensor reports fuel pressure in the rail so the computer can precisely control fueling and the fuel pump. When the reading is implausible — too steady, erratic, or inconsistent with commanded pressure — this code is set, sometimes with hard starting, hesitation, or reduced power. It generally points to the sensor or its wiring, though an actual fuel-pressure problem can also trigger it. Typical repair costs on Land Rover range from $800 to $2,000, depending on the specific model and root cause.
Common Causes of P0191
- •Faulty fuel rail pressure sensor
- •Corroded, loose, or damaged sensor connector
- •Open, shorted, or high-resistance sensor wiring
- •Actual fuel pressure out of range (weak pump or regulator)
- •Restricted fuel filter or supply line
- •Loss of reference voltage or ground from the ECM/PCM
- •Faulty fuel pressure regulator or control valve
P0191 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 P0191 mean on Land Rover?▼
P0191 stands for "Fuel Rail Pressure Sensor Circuit Range/Performance." This code sets when the fuel rail pressure sensor's signal is out of its expected range or doesn't match what the computer expects for current conditions. On direct-injection and many modern engines, this sensor reports fuel pressure in the rail so the computer can precisely control fueling and the fuel pump. When the reading is implausible — too steady, erratic, or inconsistent with commanded pressure — this code is set, sometimes with hard starting, hesitation, or reduced power. It generally points to the sensor or its wiring, though an actual fuel-pressure problem can also trigger it. On Land Rover specifically, this code is documented across 1 model.
