How Long Does an Injector Control Pressure Sensor Last?

A diesel engine is a very sensitive and complicated piece of machinery. Getting a diesel to crank will require a number of parts to work together. Among the most vital systems on a diesel engine is the fuel injection. In order for this system to work properly, there will need to be a certain level of pressure. The pressure will help to disperse the right amount of fuel during the combustion process. The injector control pressure sensor is what tells the engine computer how much pressure there is in the fuel rail. The engine computer will then use this information to ensure that the right amount of fuel is dispersed during the starting and running of the vehicle. Each time that you try to start your diesel engine, the injector control pressure sensor will be a part of the process.

Just like any other sensor or switch on your diesel engine, the injector control pressure sensor is supposed to last as long as the vehicle does. The grueling and unforgiving conditions that this sensor has to operate in can cause it to go bad over time. In most cases, the reason why this sensor will fail is due to wiring issues. The wiring that goes to the injector control pressure sensor will become damaged over time due to the heat that it is exposed to.

Due to the importance that the injector control pressure sensor plays in the overall functionality of a car, it is important to let professionals handle the repairs needed. Trying to do this type of work with no experience may lead to other components of the fuel system becoming damaged. Letting a professional handle this work will ensure it is done the right way and that there will be no further issues with the injector control pressure sensor.

The following are some of the things that you will notice when this sensor is not working properly:

  • The engine is stuttering while trying to accelerate
  • The engine idles very rough and dies out
  • The Check Engine Light is on

Getting the issues with your injector control pressure sensor fixed by a professional will alleviate a lot of the stress that can come with this type of repair.
