Copyright 2023 Mechanic Base. The following P-codes (DTCs) are OBD II failure codes and generic to all OBD II compatible cars and could appear, if your fuel rail pressure sensor is faulty. Here are the facts about the fuel-rail-pressure-sensor.1) The only reason why the Fuel Rail Pressure Sensor was developed was to make the Fuel-Pump last longer.2) Before the Fuel Rail Pressure Sensor was developed, the fuel pump was always woking at 100% load.3) Using the Fuel Rail Pressure Sensor, the fuel pump module regulates the pump's rotational speed, according to engine load.4) The Fuel-Pump module computer sends a Pulse-Width-Modulation signal to the fuel pump.5) At idle, the need for excess fuel is reduced, so the fuel pump's speed is reduced, with input from the Fuel Rail Pressure Sensor.6) The Fuel Rail Pressure Sensor has 3 wires, the sensor ground, 5 volt reference and the signal wire.7) The Fuel Rail Pressure Sensor is used on returnless fuel systems.8) A vacuum hose is used in the Fuel Rail Pressure Sensor to take engine vacuum into consideration when measuring the fuel pressure.
