What are the symptoms of a faulty fuel gauge sensor?
The first and most common symptom of a faulty fuel gauge transmitter is that the fuel gauge behaves irregularly and is not related to the actual fuel level. It can go from full to empty and back in a short space of time.
Where is the sensor on the fuel pump?
This sensor is located inside the fuel tank close to the fuel pump. The sensor has a level floating arm which feels the level of the fuel inside the tank. Then the fuel gauge sender is sending the information directly to the instrument cluster and the fuel gauge.
How does a fuel pump work on a gas gauge?
The fuel pump module includes the fuel sending unit, used by the gas gauge to detect and display fuel level. https://www.flickr.com/photos/3ndymion/33556245572. The gas gauge is a relatively simple circuit, but its simplicity means each component is essential to its function.
When do you need to replace the fuel gauge sender?
If your fuel gauge behaves erratically or is stuck on full or empty, you may need to replace the fuel gauge sender. 1. Fuel gauge behaves erratically 2. Fuel gauge stuck on empty 3. Fuel gauge stuck on full The fuel gauge sender is a component that is found in the gas tank of most road going vehicles.

What do I do if my gas gauge is not working?
In most cases, to gain access to the fuel tank sending unit mount / fuel pump mounting hole, you’ll need to drop the gas tank down. Be sure to do this when there is either minimal gas in the vehicle, or it’s been siphoned out.

How can I check the fuel gauge level?
The most correct way to check the fuel gauge sensor is to lift it off the fuel tank and measure the ohmic value with a multimeter and make sure that the ohmic values change as you either raise or lower the float. Again, check your repair manual for the correct ohm value for your particular vehicle.
Where is the fuel level sensor on a gas tank?
Once the lock ring is off, take the transmitting device out of the gas tank. Locate the fuel level sensor, which is often situated on the very bottom part of the transmitting device. Remove the clip from the harness and slide off the sensor.

How to test and replace a fuel level sensor?
How to test and replace a fuel level sensor. Because it’s an in-tank fuel pump, the hardest job is removing the fuel pump from the vehicle. Doing this test can help you pinpoint why the fuel gauge is not working. If this sensor is indeed working on your vehicle, then check the fuel gauge itself. This specific vehicle is a 2010 Subaru Impreza.
