The fuel pressure sensor is a critical component in modern vehicles, responsible for monitoring the fuel pressure within the fuel rail. This sensor provides vital data to the Engine Control Module (ECM), which uses it to adjust fuel injection timing and quantity, ensuring optimal engine performance. However, like any other component, the fuel pressure sensor can malfunction, leading to issues such as poor engine performance, reduced fuel efficiency, and even engine stalling. In this article, we will explore the symptoms of a faulty fuel pressure sensor, how to diagnose and reset it, and provide a comprehensive guide on replacing it if necessary.
