2005 Ford Expedition Fuel Rail Sensor

Ford Expedition

On the 2005 Ford Expedition, the P0174 is pointing to a problem with Bank 2 running too lean. The P0193 is pointing to a fault with the Fuel Rail Pressure Sensor. With the FRP Sensor being faulty, there’s a good chance this is the reason Bank 2 is running lean. Inspect the electrical connector to the FRP Sensor and make sure there are no loose, broken or damaged wires. Inspect the vacuum line to the bottom on the FRP Sensor and make sure there are no cracks, holes or loose connections. Make sure there are no fuel leaks on the fuel rail. If the visual inspection checks ok, replace the FRP Sensor. You can find the sensor located on the top, driver’s side of the engine.
