How does a WiF sensor work?
The WiF sensor uses the difference of electric conductivity of water compared to diesel and gasoline to determine the presence of water. The WiF sensor can consist of two electrodes that reads the level of resistance in the fluid or between the ground and the electrode.
Which sensor is fitted to a diesel fuel filter?
Fuel pressure sensors All common rail diesel injection systems are fitted with pressure sensors whose function it is to monitor the condition of the fuel filter.
Where is the WiF sensor?
The WIF sensor is located at the rear of the vehicle between the fuel tank and the frame rail.
Why does diesel get water in it?
Diesel engines produce water when hot fuel from the injectors is returned to the fuel tank; this produces water from condensation, which settles under the fuel.
What does a fuel filter sensor do?
Inside the fuel filter is a fluid level sensor that keeps track of the amount of water that has been collected. Once the level starts reaching maximum capacity, the fuel filter warning light will illuminate to let you know to empty the filter.
How do you remove water from diesel fuel?
To get water out of your diesel fuel, you need to drain or pump as much water out of your fuel tank as possible. Remember to use a siphon hose long enough to reach the bottom of your tank. Add the proper amount of Diesel 911 (or your preferred diesel additive) to your fuel tank.
How much is a fuel sensor?
The cost of a fuel level sensor replacement can vary depending on different factors. Parts alone can cost anywhere between $20 and $270, according to your vehicle’s year, make, and model.
How often should a diesel fuel filter be changed?
every 10,000 to 15,000 miles
Diesel fuel is by nature, quite dirty, so it makes sense that the fuel filter is one of the most important filters on any diesel application. They usually require a change every 10,000 to 15,000 miles whereas a modern gasoline fuel filter could go 100K+ miles before a change is needed – if at all.
How serious is a fuel pressure sensor?
The fuel pressure sensor is one of these sensors, and if it fails then it can significantly decrease your car’s ability to supply its engine with the right amount of fuel. This can lead to symptoms like weak acceleration, difficulty starting the car, stalling, and poor fuel economy.
