Bosch Diesel Fuel Rail Pressure Sensor

The Bosch Diesel Fuel Rail Pressure Sensor, also called a fuel rail pressure sensor or common rail pressure sensor, monitors fuel pressure in the common rail of a diesel injection system. It sends a signal to the engine control unit (ECU). The ECU uses that signal to regulate injection pressure, fuel delivery and injection timing.

Key Features:

• Measures fuel pressure in the high-pressure rail and sends a real-time electrical signal to the engine control unit
• Helps the engine run smoothly, respond well, and meet emissions targets by supporting accurate closed-loop pressure control
• Built for the heat, vibration, and high pressures of diesel common rail systems
• Made by Bosch, a leading original equipment supplier of diesel injection technology
• Direct-replacement design that restores factory-style sensing performance

A failing rail pressure sensor can cause hard starting, rough idle, loss of power, stalling, or a check engine light. Replacing it with a quality Bosch sensor helps restore proper fuel pressure regulation and dependable diesel engine performance. Choose the correct item from the product options for your application.
