Why does my water in fuel light keep coming on?
Water In Fuel light means mostly there is some water in the fuel and the sensor found at the bottom of the fuel filter is telling you this but.. Sometimes this can be a wrong reading too. We do have a thumb screw under the bottom of the filter for draining off some water or fuel.
Can you drive with water in fuel light on?
You have no leg to stand on if your water in Fuel light is on, make sure it is documented. They should replace the WIF sensor and wiring no questions. I would not let them get away without doing something. That is a very important light and needs to function as designed, it’s the last line of defense.
What does water in fuel warning mean?
The Water in Fuel Sensor or WiF sensor indicates the presence of water in the fuel. The WiF is used especially in the Common Rail engines to avoid the Fuel injector damage. The WiF sensor uses the difference of electric conductivity of water compared to diesel and gasoline to determine the presence of water.
How does a fuel water sensor work?
The Water in Fuel Sensors or WIF-1250 liquid level sensors are solid-state devices designed to detect the presence or absence of water in fuel. The presence of water completes the circuit which, in turn, changes the condition of the transistor output.
How do you test water in a fuel sensor?
The WiF sensor uses the difference of electric conductivity of water compared to diesel and gasoline to determine the presence of water. A water sensor can detect the presence of water, often by measuring the electrical conductivity of the water present and completing a circuit to send a signal.
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.
What are water level sensors?
Level sensors are used to detect the level of substances that can flow. Such substances include liquids, slurries, granular material and powders. Such meaurements can be used to determine the amount of materials within a closed container or the flow of water in open channels. …
