Where is the Fuel Rail Pressure Sensor on a 2003 Crown Victoria?
The fuel rail pressure sensor (FRPS) on a 2003 Crown Victoria is located on the fuel rail itself. It's a small sensor, often cylindrical, mounted directly to the fuel rail near the intake manifold. You'll likely need to access it from the top of the engine, possibly requiring removal of some components for better visibility and access. A shop manual or online diagrams specific to the 2003 Crown Victoria's 4.6L engine will show the precise location with more clarity.
