All about fuel pressure sensor


What is fuel pressure sensor and how it works?

A fuel pressure sensor measures the pressure inside an automobile’s fuel tank. They are a component of the returnless fuel injection system, which is installed in almost all vehicles that are produced today. The fuel pressure sensor is attached to the fuel rail. More specifically, the sensor is connected to a tube called the common rail, which acts as a supply line for pressurized fuel. The pressurized fuel is then sent to the engines by fuel injectors. You can learn also some more about fuel pressure regulators here.

fuel pressure sensorThe fuel pressure sensor is essential for this system to function. The small electronic device serves as the module to gather critical data used by the computer regarding fuel pressure. This computer is called the power control module, also known as PCM.  With the data provided by the fuel pressure sensor, the PCM regulates the quantity of fuel to be released from the engine.

As the fuel pressure sensor allows the engine to draw only the amount of fuel it needs, the main effect is a reduction of evaporative emissions. The PCM and the fuel pressure sensor ensure that there is no retention of fuel in the vehicle’s fuel line. However, the fuel pressure sensor is susceptible to damage, as it is considered to be one of the weakest components of a returnless fuel injection system. Usually, an error code is displayed in the dashboard once your fuel pressure sensor experiences a malfunction. Other signs include a noticeable change in engine performance such as irregular transmission, stalling, and failure to start the engine.


Diesel Fuel Pressure Sensor

In a common rail diesel, injection pressure is regulated and monitored by the electronic diesel control unit. The diesel fuel pressure sensor is more rugged than a regular fuel pressure sensor. The sensor operates on five volts and provides a 0.5 to 0.45 volts analog output proportional to pressure. The sensor provides highly reliable and repeatable measurements.


The sensor is the feedback component in a controlled loop and informs the electronic diesel control unit the pressure in the rail. Also known as the ECM, the ECM can then tell the pump to increase or decrease fuel output accordingly. The ECM controls the pressure limiter to control pump pressure when you press the pedal. The ECM will immediately calculate how much fuel to give the engine based on speed, load, and aninternal calibration table. The sensor gives a continual feedback of rail pressure used by the ECM to make pressure adjustment instantaneously.
