Fuel Level Sensor

Fuel level sensor measures the tank charge level. The exact information about filling is transmitted to the fuel indicator. So the driver always knows how much fuel is there in the tank. In practice this function is very important, because without tank charge fuel measurement the driver would has to estimate exactly fuel consumption or regularly to measure tank charge fuel by him. In many makes of cars there are installed two fuel level sensors - one is on the driver’s side and another is situated on the place near the driver.

If the fuel indicator shows wrong information or constantly shows different numbers, this means that it is broken down. If the mistake appears when the tank is partially filled, in the majority of cases you need to search the mistake on the side near the driver, in other cases – on driver’s side. Before fuel level sensor’s substitution its content must be minimal. In this case the substitution won’t cost a lot. As a new sensor costs a lot, there is no need to substitute it. Sometimes you may install an old sensor with fewer costs.

In many cars it is necessary to have a special wrench to substitute the sensor. If the driver has it, then he can remove the sensor and install it back with little effort. If it is broken, don’t postpone the repair. Because of wrong data, for example, the car can stop as there won’t be fuel in the tank. If you need liquid cooling radiator, ignition runner, ABS system sensor, control block, cylindrical gear, ignition coil, central lock blocking or another part for your car, our online shop is that place where you will find a wide range of spare car parts.

HOW TO DETECT MALFUNCTION OF THE FUEL LEVEL SENSOR

First, inspect the component. In many cases, damage of the moving contacts is caused by oxidation under the action of water and dirt which takes place in course of time.

Resistance of the component should also be checked with the use of an ohmmeter. Note that the level of fuel in the tank will influence the results of measurement; therefore, the tank should be either empty or full to the top. If the tank is empty, resistance of the sensor should be between 230–330 Ohm. If the tank is full, the resistance should be 6 to 7 Ohm.

If the indicator does not react to changing the amount of fuel in the tank, dismantle the dashboard and check the wiring.

The component should be diagnosed together with the fuel system once a year, or after every 60 to 80 thousand kilometers in mileage.
