Fuel Rail Pressure Sensor – Range Rover Sport L320 L494 – 0281006064

Restore correct fuel rail pressure regulation and reliable starting on your Land Rover Sport with this direct-replacement fuel pressure sensor — also known as the fuel rail pressure sensor, FRP sensor or fuel pressure transducer. Built to OEM specification and matching part numbers BC3Q9F838AA, BC3Z9F838A, LR020693, 0281006064 and 9F838. Also fits equivalent Citroën, Jaguar and Peugeot models.

Common signs of failure

A failing fuel pressure sensor commonly logs codes P0190, P0191, P0192, P0193 or P0194 (fuel rail pressure sensor circuit faults). Symptoms include hard starting (hot or cold), prolonged cranking, stalling at idle, hesitation under acceleration, intermittent loss of power, and on common-rail diesels the vehicle dropping into limp mode. A failed sensor can also cause the ECU to default to incorrect injection timing, hurting fuel economy and emissions.

Fitment notes

Direct-fit replacement, no coding required after fitting. Relieve fuel system pressure before removal (depressurise via the dedicated fuse procedure on most cars). Use a new sealing washer or O-ring if supplied, and torque to manufacturer spec — over-tightening can crack the sensor body. Clear codes with any OBD2 scanner after installation. Position: Engine Compartment.

Frequently asked questions

Can I drive with a P0190 code?

Short distances only. A faulty fuel pressure sensor causes incorrect fuelling, which on common-rail diesel engines can damage injectors over time. Replace promptly.

Is this the same as a fuel pump?

No — the pressure sensor measures fuel pressure in the rail and reports it to the ECU. The fuel pump is a separate component that actually moves fuel from the tank. They commonly fail together but are distinct parts.

Do I need to bleed the fuel system after fitting?

Most modern cars self-prime when you cycle the ignition. On older common-rail diesels, follow the service-manual bleed procedure to clear air from the high-pressure circuit.
