How Long Does a Fuel Rail Sensor Last?

fuel rail sensor

The amount of pressure that is in a car’s fuel system is important and something that is heavily monitored. Without the proper amount of fuel pressure, the gas will not be able to properly circulate. This lack of circulation will usually result in the car stalling out and not be able to run as intended. The fuel rail sensor is among the most important pieces in regards to keeping the right amount of pressure in your fuel system. This sensor runs continuously in order to ensure that there is enough pressure in the fuel system.

Just most of the sensors or switches on your vehicle, the fuel rail sensor is designed to last for the life of the vehicle. The sensor will usually need to be replaced due to wear on the terminals that it has. The heat and moisture that this switch has to deal with will start to corrode and create rust spots on the terminals. Having damage on the terminals of the switch will lead to it not making contact and not getting proper readings regarding the fuel pressure. Noticing the signs that your car is giving when the fuel rail sensor is damaged and getting the proper repairs done is the only way to avoid an unstable fuel system.

In most cases, when a sensor or switch is bad the first thing that you will notice is the illumination of the Check Engine Light. The engine computer is continuously monitoring the sensors and switches of a car and when a problem is detected is will turn on the check engine light to alert the vehicle owner.

The following are some of the other signs that you may notice when it is time to get the fuel rail sensor on your car replaced:

  • The car will not start
  • The car runs inconsistently
  • The car dies out after being ran for a short time

The last thing that you want is to have your car running inconsistently due to an issue with the fuel system. Getting the fuel rail sensor replaced by professionals will help to reduce the time that the car is down for.
