Fuel Rail Pressure Sensor – Ford Focus II Kuga I – 2005-2012 – 7M5N9C968AA

Get your Ford Focus II (2005–2012) back to correct fuel rail pressure regulation and reliable starting with this replacement fuel pressure sensor, also referenced in service manuals as the fuel pressure transducer or high pressure fuel sensor. Built to OEM specification, matching 0261230238, 0261230239, 31251447, 31272732 and 7M5N-9C968-AA. Also fits equivalent Land Rover and Volvo 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. Standard 4 pin connector. 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.
