Fuel Rail Pressure Sensor
The fuel rail sensor, commonly referred to as the fuel pressure sensor, is an engine management component that is commonly found on diesel as put of the Fuel injection system.
It is a part of vehicle’s fuel system and designed to monitor the fuel pressure that is present at the fuel rail. The sensor sends this signal to the ECU, which then uses it to make adjustments to the vehicle’s fuel and timing. When the sensor has an issue it can cause problems with the performance of the vehicle.
Usually a failing fuel rail sensor will produce a few symptoms that can alert the driver to a potential issue.
Common Rail Pressure sensor failure are as follows;
- Hard starting
- Lack of power, acceleration and fuel efficiency
- Engine Management Light on (EML)
Potential problem with the fuel rail sensor is hard starting. A faulty fuel rail sensor may send an inaccurate signal to the ECU which may cause the engine to experience hard starting. The engine may take a few cranks longer than normal to start and in more serious cases may not start at all.
A faulty rail sensor may upset the air fuel ratio and cause the vehicle to experience performance issues such as a decrease in power, acceleration, and fuel efficiency, and in some cases may even experience stalling.
If the ECU detects an issue with the fuel rail sensor signal or circuit, it will set off the EML - Engine Management Light to notify the driver of the issue. The EML can also be activated by a wide variety of other issues, so having the computer scanned for Fault codes is highly recommended.
