Fuel Pressure Sensor

The engine depends on an accurate mixture of air and fuel to run flawlessly. The fuel pressure sensor is key to making sure that the runs perfectly, also it sends information to the powertrain control module (PCM) about the pressure in the fuel rail which gives the PCM control over the pressure.

Fuel pressure sensor

The fuel pressure sensor is in control of keeping track of the fuel pressure inside the fuel rail. Once the sensor detects the information, the data gets sent to the engine control unit which is then analyzed by the computer. That way the computer can make any changes to the timing of the fuel injection and the quantity of the fuel being pushed in.

Aside from being able to measure the pressure inside the fuel tank, it can also recognize a leak. The computer is always attentive to the information it receives by making adjustments to the timing. The fuel rail pressure is an important component, especially with the vehicles being made more environmentally friendly.

Common issues with a faulty fuel pressure sensor

A faulty fuel pressure sensor can lead to the vehicle having trouble starting, poor engine performance, and stalling.
