COMMON RAIL PRESSURE SENSOR FAILURE SYMPTOMS
What is the common rail pressure sensor?
Sensor operation and responsibilities
The common rail pressure sensor is responsible for measuring the exact fuel pressure in the system. This information is sent to the engine control unit, which adjusts fuel injection as necessary. In simple terms, we make sure that the engine receives the right amount of fuel at the right time.
Importance in the automotive fuel system
Precision is key in the diesel world. A faulty or inaccurate common rail pressure sensor can lead to performance and efficiency problems. We firmly believe that the health of this sensor is essential to the proper functioning of the automotive fuel system.
Common symptoms of pressure sensor failure
Identifying the symptoms of a faulty common rail pressure sensor is the first step in troubleshooting the problem. Throughout our experience at Herlic.es, we have identified several symptoms that indicate possible problems with this sensor.
Warning light on the dashboard
One of the first signs of a faulty sensor is the appearance of a warning light on the dashboard. If this light comes on, we recommend taking the vehicle to a specialist for a detailed check.

Decrease in acceleration power
If you notice that your vehicle is not accelerating like it used to, it could be an indication of a problem with the pressure sensor. We have observed that a faulty sensor can affect fuel delivery to the engine.
Problems starting the engine
A hard start or an engine that won’t start at all can be the result of a malfunctioning common rail pressure sensor. We know how frustrating this can be, and we’re here to help.
Unexpected vehicle stops
If your vehicle stops unexpectedly while in motion, it could be due to a pressure sensor failure. We have seen how this problem can be dangerous, especially on busy roads.
Reduced fuel efficiency
Finally, a noticeable decrease in fuel efficiency may be a sign of a faulty sensor. We understand the importance of fuel efficiency, and recommend a checkup if you notice excessive consumption.

Common causes of sensor failure
The common rail pressure sensor is a vital part of the diesel fuel injection system. However, like any component, it is subject to failure. At Herlic.es, we have identified some of the most common causes of failure in these sensors over our years of experience.
Sensor wear and aging
Every component has a service life, and the common rail pressure sensor is no exception. With time and continuous use, the sensor can wear and age, leading to inaccurate readings or complete failures. We have found that regular maintenance and timely replacement of the sensor can prevent many wear-related problems.
Electrical or connection problems
Sensors, being electrical components, depend on proper connections to function correctly. A loose cable, corroded connector or any other electrical problem can interrupt the sensor signal. At Herlic.es, we recommend periodic checks of the electrical system to ensure that everything is in order and to avoid unexpected failures.
Contamination or physical damage
The environment in which a diesel engine operates can be hostile. The common rail pressure sensor can become contaminated with dirt, oil or even water. In addition, physical impact or damage can affect its performance. We have seen how even small particles of dirt can cause erroneous readings, so it is essential to keep the area around the sensor clean and protected.
At Herlic.es, our goal is to provide our customers with the best information and solutions to keep their vehicles in optimal conditions. If you suspect you have a problem with your common rail pressure sensor or any other component, we are here to help. Our experience and customer-centric approach make us a leader in the field of diesel repair and maintenance.
Solutions and recommendations
Inspection and cleaning of the sensor
Before considering replacement, it is essential to perform a detailed inspection of the sensor. Often a simple cleaning can solve many problems, especially if contamination is the cause. We recommend regular inspection to ensure that the sensor is functioning properly.
Replacement of defective sensor
If after inspection and cleaning the sensor still does not function properly, it may need to be replaced. At Herlic.es, we offer high quality sensors and guarantee proper installation to ensure optimal system performance.
Preventive maintenance
Prevention is the best solution. Regular maintenance, including inspection and cleaning of the sensor, can prevent failures and prolong the life of the component. We strongly believe in the importance of preventive maintenance to avoid long-term problems.
Sensor location and technical characteristics
The common rail pressure sensor is a technical part with precise specifications that may vary according to the model and make of the vehicle.
Differences according to the model and make of the car
Not all common rail pressure sensors are the same. Depending on the model and make of the car, the sensor may vary in size, shape and technical specifications. At Herlic.es, we have a wide range of sensors to suit the needs of each vehicle.
Electrical connections and signals
The common rail pressure sensor is connected to the vehicle’s electrical system and sends precise signals to the engine control unit. It is essential to understand the electrical connections and signals to ensure proper installation and operation.
