It is time for you to know where is the fuel rail pressure sensor located so you can watch out for its symptoms. This sensor is found in some gasoline and diesel engines that you will have in your car. You can locate the sensor in the middle of the rail in the fuel associated with the ECU or vehicle computer.
You don’t have to confuse the fuel rail pressure sensor with the tank pressure sensor because they are different. This unique sensor for the tank is inside the tank, while the sensor is between the fuel rails. You can tell how much gasoline you have left in the tank by the engine’s control unit with this sensor.
What Is The Function Of The Fuel Rail Pressure Sensor?
The purpose of the fuel rail pressure sensor is to track the pressure generated by the fuel. All this information that the sensor detects will pass to the ECU for you to be attentive. With the engine control unit attached to the sensor, you will know when the engine is prone to failure.
Many possible faults that occur in the sensor, the control unit will try to solve them before sending you an alert. With this automatic synchronization between ECU and sensor, you will have the best performance in your engine. These fuel rail pressure sensors are available on newer vehicles.
The engine unit will keep track of the amount of fuel injected from the tank to the engine. This unit will not let more than the right amount of fuel being injected, saving you money on refills. With this fuel control, the parts that make up the engine will not be easily damaged, and your car will not be so toxic.
The sensors have been implemented in new vehicles so that you have an economic unit. You will not have to invest so much money in fuel because you will have this sensor on your side.
Can The Fuel Rail Pressure Sensor Be Damaged?
Even if you think it is impossible, the fuel rail pressure sensor can easily be damaged. Due to exposure to fuel or having faulty compounds, your sensor can suffer some damage. You may have a false analysis of the vehicle’s fuel timing which changes its performance.
Time can also be bad for this sensor, where you will have to replace it to improve its performance. It may be that the year you buy the vehicle, this sensor fails or perhaps for a longer time.
Main Symptoms Of Fuel Rail Pressure Sensor Failures
Sometimes you can experience fuel rail pressure sensor failures for a variety of reasons. Among the main symptoms that indicate a faulty fuel rail pressure sensor is:
- Engine starts hard
With a bad fuel rail pressure sensor, the control unit will not pass a good amount of fuel to the engine. With little fuel in your engine, the vehicle will not start, or if it does, it will take a long time.
This is a degenerative problem in which your engine will start with difficulty at first, but later, it will not be able to do anything. You have to replace your fuel rail pressure sensor before your car doesn’t run anymore.
- The engine fault light appears
If the fuel rail pressure sensor fails, the “Check Engine” light will appear on the dash. This light will activate almost automatically when the engine has fuel problems. Although the warning signal may mean another fault, you should check it if you have suspicions about the sensor.
You can know that the duct pressure sensor is the culprit of the failure to use scanners. With a good tool to scan your vehicle, you will get rid of doubts regarding sensor failure. Some codes that indicate this type’s faults are P0191, P0194, or P0193 in the control unit.
- The mileage is wrong
If the fuel pressure sensor is damaged, you may notice a drop in fuel economy. Your car will lack control managing the fuel in which it will send too much or too little. Mileage can mark the wrong way, leaving you in endless doubt about how much fuel you have left.
When you have a large vehicle, it is not profitable to drive with a damaged fuel pressure sensor. The amount of fuel you can spend will be considered, making you lose a lot of money.
- You will suffer from traffic jams
Your vehicle’s engine can choke as the fuel rail pressure sensor weakens. You may be driving around town, and the engine will only shut down due to lack of fuel. Driving with this problem will prove to be a challenge, and it can also attract many dangers in your life.
You have to take your vehicle to the mechanic as soon as possible to replace the sensor and forget about the faults. You should prevent vehicle accidents with things that could have been avoided.
- Acceleration will be very low
When you step on the accelerator pedal, and your vehicle does not accelerate what it should, it is due to the fuel pressure sensor. The control unit that dominates your car does not transmit a proper signal, and this affects acceleration. You will notice how the performance of your vehicle declines as the days go by with the failure.
How Much Can It Cost To Change A Fuel Rail Pressure Sensor?
You can detect the symptoms of the fuel rail pressure sensor and find a way to repair it. This device is very complicated to understand, and therefore, it is not convenient for you to change yourself. You will have to ask for professional help to change the part and improve your vehicle’s performance.
For a new fuel rail pressure sensor, you will have to pay roughly $ 100. These sensors are very easy to find depending on the model of your vehicle. You can buy the sensor from the official supplier of your car to have guarantees on its operation.
After having the pressure sensor on hand, you will have to contact a trusted mechanic to install it. The cost of labor can be an extra $ 100 or even $ 200 if things go wrong. Other faults can arise in your engine by injecting too much fuel due to the rail pressure sensor’s problems.
Maybe with the sensor’s change, you will have to replace some spark plugs or do maintenance on the vehicle. It is convenient to install the sensor in your vehicle and test it at the mechanic shop before removing it.
Is The Fuel Rail Pressure Sensor On All Vehicles?
Now that you know where the fuel rail pressure sensor is located? You must think that it is found in all vehicles, but you are wrong. These sensors are built into the vehicles of the last decade integrated into the engine control unit. Many vehicles have the ECU but not the fuel rail pressure sensor.
This system is great for you to save money on fuel, but it also creates many problems. With classic cars, you will not have the sensor, and you will feel that you get the control in the fuel, but with the sensor, that is forgotten. If the sensor is damaged, all the fuel economy advantages work against you, and their replacements can be expensive.
You have to think carefully about buying a vehicle with or without the integrated sensor to monitor your fuel. In large vehicles, many disadvantages of the technology can be noticed when it has some defects.
What Other Option Do I Have Not To Replace The Fuel Sensor?
If you want to save money and not replace the fuel rail sensor, you can try cleaning it a bit. Now that you know that this item is in the fuel tank center, you can locate it. You can use a wire brush or anything else to clean the sensor.
Many mechanics claim that cleaning a faulty sensor won’t make a difference, and you waste your time. You have to save money and replace the sensor because it is the most feasible. These sensors are also not rebuilt, so you don’t try to do it from home.
How Do I Know If The Sensor Is Damaged Without Going To A Mechanic?
You do not waste time or money on the mechanic when checking if the sensor is damaged; analyze it yourself. You can use a scanner to diagnose your vehicle that will confirm the real fault. These scanners have a series of codes that you have to abide by to know the problem.
The scanners are 99% efficient and reliable for you to use from home and save money. The time that you can invest in analyzing your vehicle with the scanner can be 5 minutes.
You have to know how a fuel rail pressure sensor works to know when to replace it. These sensors are a novelty in which you will have better management of your diesel fuel. Sensors tend to be damaged by time or because they are of poor quality, and you must know when to change them.
When you mount a new sensor in your vehicle, you will be able to use it for many more years, saving you gas. A faulty fuel rail pressure sensor can cause serious damage to your car, so it needs to be replaced.
