P0191 on Land Rover by model: symptoms, diagnosis and fix
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.
Common Symptoms
- Hard starting especially when warm
- Rough idle and misfires
- Loss of power under acceleration
- Check engine light with fuel rail pressure codes
- Engine stalling at low speeds
How to Fix
Replace the high-pressure fuel pump and cam follower with the updated design. Check the low-pressure fuel pump is delivering adequate supply pressure. Clear adaptation values after replacement.

Owner tips & cautions
- TipIf your Evoque has the original fuel pump, ask the dealer about the updated part during your next service. The updated cam follower is a significant improvement.

Frequently asked questions
What does P0191 mean on a 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 it is documented across 1 model: Range Rover Evoque.
What are the most common causes of P0191?
The most common causes of P0191 are: 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. The specific cause varies by vehicle.
How much does it cost to fix P0191 on a Land Rover?
Published repair estimates on Land Rover range from $800 to $2,000 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
