55PP19-02 Rail Pressure Sensor
2024 05/02
The 55PP19-02 Rail Pressure Sensor is a component used in the fuel injection system of a vehicle. It is responsible for measuring the pressure of the fuel in the fuel rail and sending this information to the engine control unit (ECU). The ECU then uses this data to regulate the fuel injection timing and quantity to ensure optimal engine performance and fuel efficiency. The rail pressure sensor is typically located on or near the fuel rail and is connected to the ECU through a wiring harness.
