the fuel pressure sensor (operating principle, symptoms)

The injector control pressure sensor is an engine management component commonly found on diesel engines. As the name suggests, it is an electronic sensor that controls the pressure of the fuel that feeds the injectors. Diesel engines require a particularly well-tuned fuel mixture, because they rely on pressure and temperature to ignite the fuel mixture, instead of a spark. The injector control pressure sensor senses the pressure of the fuel supplying the injectors and sends that signal to the computer so it can make the necessary adjustments to achieve optimal performance and efficiency. When there is a problem with this sensor, the signal can be compromised, which can lead to vehicle performance issues. To go further on the subject, also discover our article on the symptoms of a faulty fuel injector.

1. Booting Problems

One of the first symptoms of a possible problem with the injector control pressure sensor is difficulty starting the engine. Diesel engines do not have a spark ignition system, and therefore require a finely tuned fuel mixture for proper ignition. If the control pressure sensor has problems, the signal from the computer to the injectors may be out of adjustment, which can cause problems when starting the engine. The engine may require more turns than normal, or several turns of the key, before starting.

2. Improper engine operation and decreased power, acceleration and fuel consumption.

Another symptom of a possible problem with the injector control pressure sensor is an engine performance problem. A faulty sensor can disrupt the fuel mixture and cause misfires, loss of power and acceleration, decreased fuel mileage, and in some cases, stalling. Similar symptoms can also be caused by other problems, so a good diagnosis is recommended to be sure of the problem.

3. Check engine light comes on

An illuminated check engine light is another symptom of a potential problem with the vehicle's injector control pressure sensor. If the computer detects a problem with the injector control pressure sensor or circuit, it triggers the check engine light to notify the driver. An illuminated check engine light can also be triggered by a wide variety of other problems, which is why it is highly recommended to have the computer scanned for trouble codes.

Injector control pressure sensors are most commonly found on diesel engines, but they can also be found on vehicles with gasoline engines. If you think you have a problem with the injector control pressure sensor, have the vehicle inspected by a professional technician, such as those listed on bolid.be, to determine if the sensor needs to be replaced.
